Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 2 to 15, a light guide film 1 according to an embodiment of the present invention includes a flexible film 11 and a separator 12.

The flexible film 11 has a plurality of light emitting units 110 for guiding light and emitting light, and the light emitting units 110 have at least one light incident portion 111 for providing incident light, at least one light guiding portion 112 having a light guiding surface 1120 for emitting the incident light at an arbitrary angle, and a light emitting portion 113 for dispersing and emitting the light transmitted by the light guiding portion 112.

The partitions 12 serve and form several light emitting units 110. The separator 12 includes a separator 121, an optical fiber 122 embedded in the separator 121, and a light emitting terminal 123 connected to the light incident part 111. One end of the optical fiber line 122 extends to connect to an external light source, and the other end is connected to the light emitting terminal 123, so that light emitted from the external light source is transmitted to the light emitting terminal 123 via the optical fiber line for secondary emission, so as to provide light required by the light emitting unit 110.

In the embodiment of the present invention, the light emitting unit 110 with light guide is formed inside the flexible film 11, the light emitting unit 110 has the light guide portion 112, and the light guide portion 112 has the light guide surface 1120 which enables incident light to be refracted and diffracted at any angle, so that the incident light can be totally reflected and fully diffracted, and the incident light can be uniformly distributed in the light emitting unit 110 through the light guide surface 1120, which is beneficial to forming a uniform surface light source on the light guide film 1, and broadens practical application scenarios thereof.

Specifically, the flexible film 11 has a plurality of identical light emitting units 110, and these light emitting portions 113 can emit identical or substantially identical light for external use or for treatment or maintenance use by a user. This enables the flexible film 11 to have substantially the same light emission effect at each part of the whole.

Specifically, the light incident portion 111 of the light emitting unit 110 is used for connecting an external light source or an optical fiber. The light incident portion 111 is substantially distributed at the edge of the flexible film 11 or at the edges of the same plurality of light emergent units 110 in the flexible film 11. The light incident portion 111 can provide light energy required by the light emergent portion 113 at the edge position of the light emergent portion.

Furthermore, the flexible film 11 provided by the embodiment of the present invention further includes a partition 12 for partitioning and forming a plurality of light emitting units 110, and the partition 12 can partition the light incident portion 111, the light guide portion 112, and the light emitting portion 113 in a group, and can connect external light to transmit light energy to the light incident portion 111, the light guide portion 112, and the light emitting portion 113, so as to uniformly emit light on each light emitting unit 110.

Thus, the separator 12 provided by the embodiment of the present invention can have the function of an optical fiber connector.

Specifically, the spacer 121 can be in any shape, which mainly functions to support the winding of the optical fiber wire 122 and the molding direction in which the optical fiber wire 122 is formed, and the molding direction of the light emitting terminal 123. The spacer 121 can be made of a low refractive index material to maintain full emissive conduction of the fiber optic energy. Such as plastics, polystyrene, polycarbonate, acrylates, silicone rubber, nylon, and the like.

The light emitting terminal 123 may be formed of a light emitting fiber to provide a desired light energy at the light incident portion 111. It is possible for the light-emitting terminal 123 to contain regenerated cellulose and a light-emitting polycyclic compound. "regenerated cellulose" refers to cellulose that has been chemically modified by various conventional methods for conversion to semi-synthetic polymer fibers, commonly referred to as rayon. A "luminescent polycyclic compound" is a compound having at least two identifiable cyclic groups that may or may not share a common bond within the ring structure. The luminescent polycyclic compound comprises a heterocyclic ring having two nitrogen atoms in the heterocyclic ring, i.e., the heterocyclic ring comprises at least two nitrogen atoms as part of a ring structure in the heterocyclic ring. The luminescent polycyclic compounds retain luminescent properties even in the presence of the harsh conditions associated with regenerated cellulose. Without being bound by any particular theory, the heterocyclic ring comprising two nitrogen atoms provides excellent stability to the luminescent polycyclic compound and enables the luminescent polycyclic compound to maintain luminescent properties even when exposed to harsh conditions associated with regenerating cellulose, such as alkaline conditions. Thus, the luminescent polycyclic compound can be combined into the cellulose solution during regeneration of the cellulose prior to spinning, and the luminescent polycyclic compound is present throughout the luminescent fiber after spinning.

In the above embodiments, due to the compound used for regenerating cellulose, the cellulose is regenerated under harsh conditions that destroy the light emitting properties of various conventional organic light emitting compounds. In particular, the cellulose is usually regenerated under alkaline conditions and at alkaline pH. However, the luminescent polycyclic compounds described herein are able to withstand such harsh regeneration conditions while maintaining luminescent properties, thereby enabling the luminescent polycyclic compounds to be combined with a cellulose solution prior to spinning.

In embodiments, the luminescent fiber is formed by combining the cellulose solution and the luminescent polycyclic compound to produce a fiber-forming composition, followed by spinning the fiber-forming composition. The luminescent polycyclic compound can be combined with the cellulose at any time prior to spinning the fiber-forming composition to form a luminescent fiber. In this regard, prior to spinning, the cellulose may be regenerated in a cellulose solution in the presence of a luminescent polycyclic compound to form a fiber-forming composition, i.e., the luminescent polycyclic compound may be present in the cellulose solution simultaneously with other compounds used to regenerate the cellulose. After spinning, the luminescent fibers are cut to the desired size. The size of the resulting luminescent fiber is not particularly limited. However, in this embodiment, the luminescent fibers have an average nominal diameter of about 3.3 to 28dtex, and may have a length of about 2-6 mm.

The luminescent polycyclic compound comprises at least two identifiable cyclic groups that may or may not share a common bond within the ring structure. At least one of the cyclic groups is a heterocycle that includes two nitrogen atoms as part of a ring structure. As described above, it is believed that the heterocyclic ring comprising two nitrogen atoms provides excellent stability to the luminescent polycyclic compound and enables the luminescent polycyclic compound to maintain luminescent properties even when exposed to harsh conditions associated with regenerated cellulose, such as alkaline conditions. Examples of suitable heterocyclic rings that may be included in the luminescent polycyclic compound include unsaturated six-membered nitrogen heterocycles, such as pyrazine, pyridine and pyridazine, each of which exhibit excellent stability and have stable aromatic rings. All rings in the luminescent polycyclic compound may be heterocyclic, or the luminescent polycyclic compound may have a combination of carbocyclic and heterocyclic rings.

Specifically, as shown in fig. 2, the flexible film 11 is divided by the partition 12 to form a plurality of divided spaces, each of the divided spaces correspondingly forms a light emitting unit 110, and the light emitting units 110 are parts capable of generating uniform light to be sequentially repeated and spliced, so as to generate a uniform light emitting effect on the whole flexible film 11.

(light emitting unit 110)

The light-emitting unit 110 in the above embodiment is disposed along the plane of the flexible film 11, and a light-emitting space 1100 is formed on the surface of the flexible film 11, the light-emitting space 1100 has a backlight surface 1101 and a light-emitting surface 1130 which are disposed in parallel, and a partition 12 surrounding the backlight surface 1101 and the light-emitting surface 1130. The light guide portion 112 is disposed between the backlight surface 1101 and the light emitting surface 1130. That is, the light emitting space 1100 has a substantially plate shape, and the light guide portion 112 is located inside. The light incident portion 111 has a light incident surface 1110, the light emitting portion 113 has a light emitting surface 1130, and the light guide surface 1120 has a light emitting rate varying from the light incident surface 1110 to the light emitting surface 1130.

The shape of the light emitting unit 110 projected on the flexible film 11 may be a circle, a triangle, a square, a regular polygon, or the like, and is not particularly limited. The following description is provided with reference to specific embodiments for the internal structure of each of the spacers 12 and the light-emitting unit 110.

In some embodiments, as shown in fig. 3-7, the projected shape of the light exit unit 110 as a whole along the plane of the flexible membrane 11 is substantially circular. The light emitting unit 110 has a light incident portion 111 formed at its periphery, and the light guide portion 112 and the peripheral space of the light guide portion 112 are located inside the light emitting unit 110.

Optionally, as shown in fig. 3 and 5, the light incident portion 111 may have a circular ring surface uniformly distributed around the light emitting unit 110, where the circular ring surface is a light incident surface 1110, which may be formed by the light emitting terminal 123. The light guide part 112 can be located at the center of the light incident surface 1110 to guide the light transmitted by the light incident part 111 at the edge to the light emitting surface 1130 of the light emitting space 1100 through refraction and diffraction, so as to form a uniform outgoing light on the light emitting surface 1130, thereby achieving the purpose of uniform emission.

Further, as shown in fig. 6 and 7, the light incident surface 1110 has a convex direction protruding toward the outer periphery of the light emitting space 1100. The light guide part 112 can be a convex shape at the center of the light emitting space 1100, the convex shape has a light guide surface 1120 with a shape substantially the same as that of the light incident surface 1110, and the light guide surface 1120 and the light incident surface 1110 are substantially symmetrical along the midpoint of the distance from the center to the edge of the light emitting space 1100. Thus, when leaving the surface, the light rays generated by the light incident surface 1110 can rapidly reach the light guide surface 1120, and are uniformly scattered by the light guide surface 1120 for being emitted.

Specifically, the light incident surface 1110 and the light guide surface 1120 are both located or mostly located on the backlight surface 1101, the light emitting surface 1130 is parallel to the backlight surface 1101, and the light emitting surface 1130 may be an opening without being blocked by a component, or may be a transparent light emitting film with an extremely small refractive index and high light transmittance. For example, the light emitting film is about 100 to 300 μm. For example, low crystallinity, fine-grained articles formed from crystalline polymers such as PE, PP, etc. by rapid cooling; these crystal particles become finer by, for example, stretching, and the transparency of the resulting optical film can be significantly improved.

In the preferred embodiment, as shown in fig. 7, the light incident surface 1110 is connected with the light guide surface 1120 to make the light rays quickly refract and scatter along the light incident surface 1110 to reach the light guide surface 1120, thereby reducing the energy loss of the light rays. Specifically, the light guide surface 1120 has a first variable curvature, and the light incident surface 1110 has a second variable curvature; the first variable curvature has a substantially small variation trend of curvature along the direction from the center to the periphery of the light-emitting space 1100, and the second variable curvature has a variation trend of curvature along the direction from the center to the periphery of the light-emitting space 1100 from small to large. Specifically, the first varying curvature has a first initial curvature K1 and a first end curvature K2, and the second varying curvature has a second initial curvature K3 and a second end curvature K4; wherein, K1> K2, K4> K3, K1> K4.

In some embodiments, the projection shape of the light exit unit 110 as a whole along the plane of the flexible film 11 is substantially a regular polygon, and the partition 12 surrounds the periphery thereof. The light emitting unit 110 has a light incident portion 111 formed at its periphery, and a light guide portion 112 and its peripheral space are located inside the light emitting unit 110.

As shown in fig. 4, the light incident surface 1110 can be a side edge surface of a regular polygonal prism formed by the light emergent space 1100, and the light emitted therefrom is emitted to the center of the light emergent space 1100 from the side edge surface approximately, and is uniformly emitted through the light emergent surface 1130 after being transmitted by the light guide surface 1120 formed by the light guide part 112.

Thus, the light guide part 112 can have a light guide surface 1120 corresponding to the side edge surface. For example, when the side edge surface is a plane, the light guide surface 1120 can be a plane and form an angle of 45 degrees with the side edge surface, so as to uniformly guide the substantially parallel light rays emitted from the side edge surface and emit the light rays from the light emitting surface 1130. When the side facets are concave, the light guide surface 1120 is also concave, so that more concentrated emergent light can be emitted from the side facets, and more scattered and uniform light can be formed by conduction and emitted from the light emitting surface 1130. Alternatively, the light guide surface 1120 also has a plurality of planes to uniformly disperse the incident light from the light incident surface 1110.

In some embodiments, as shown in fig. 8-15, each light emitting unit 110 has a light incident portion 111 that can be in a dot shape or a column shape. For example, the light incident portion 111 can uniformly disperse the light emitted from the light emitting terminal 123 to the periphery thereof. The light guide part 112 may surround the light incident part 111, and refract and scatter light emitted from the light incident part 111 to form the light exit part 113.

Specifically, as shown in fig. 9, a partition 121 is formed on one surface of the flexible sheet 11, the optical fiber 122 embedded in the partition 121 extends inside thereof, and the light emitting terminal 123 passes through the flexible sheet 11 on the one surface on which the partition 121 is formed to the other surface thereof to form a point-like or column-like light incident portion 111. Similarly, the partition body 121 forms a light guide portion 112 having a light guide surface 1120 around the light incident portion 111 on the other surface of the flexible film 11.

In this embodiment, more specifically, as shown in fig. 10, the light incident portion 111 has a narrowing section 1111 and an expanding section 1112, and the narrowing section 1111 extends from the center of the bottom surface of the light emitting unit to the direction away from the center, and is then integrally connected to the expanding section 1112. The light incident surface 111 has a surface curvature of the light incident surface 1110 at the narrowing section 1111 larger than a surface curvature of the light incident surface 1110 at the expanding section 1112, and the light incident surface 1110 is bent around in the bending directions of the narrowing section 1111 and the expanding section 1112.

Further, the light guide surface 1120 of the light guide portion 112 associated therewith may have a light extraction rate closer to the light incident portion 111 greater than a light extraction rate farther from the light incident portion 111, specifically, the light extraction rate closer to the light incident portion 111 of the light guide surface 1120 may be set greater than the light extraction rate farther from the light incident portion 111, and/or the light extraction rate closer to the light incident portion 111 of the light guide surface 1120 may be set smaller than the light extraction rate farther from the light incident portion 111.

In this embodiment, the light emitting unit further includes a light emitting film provided in the light emitting portion 113, and the light transmitted through the light guide portion 112 and/or the light incident through the light incident portion 111 is refracted and then sufficiently diffused and scattered, so that uniform light emission is generated.

The light guide surface 1120 in such an embodiment will be described in detail below.

From the light guide surface 1120 to the light far-entering portion 111 from the light near-entering portion 111, the surface light-emitting rate is gradually increased, specifically, the scattering rate and the light reflection rate are both gradually increased. When light enters from the light-entering part 111, a part of the light ray a enters the near light-entering part 111, and can directly exit from the light-exiting surface 1130 because the total reflection condition of the light guide part 112 is not satisfied; the other part of the light B enters the far-light part 111, and is reflected to the light exit film by satisfying the total reflection condition of the light guide tube, and is emitted from the light exit surface 1130 after being diffusely reflected by the light exit film. Since the light guide surface 1120 of the light guide part 112 has gradually higher scattering and reflection rates from the light incoming part 111 to the light outgoing part 111, the light outgoing surface 1130 scatters and reflects less light near the light incoming part 111 and more light near the light incoming part 111, so that the light flux of the light emitted from the light outgoing part 113 at the light incoming part 111 is less than that at the light incoming part 111 (near the end surface 24) after the light B is diffusely reflected by the light outgoing film, and the difference in the light flux of the light B can exactly compensate the light flux of the light emitted from the light outgoing part 113. Therefore, the light emitted from the light emitting surface 1130 has a good uniformity in the range from the light incident portion 111 to the edge of the light guiding surface 1120 at the outer circumference thereof after the overall measurement.

Specifically, the light guide surface 1120 may be divided into N annular zones from the center to the periphery of the light emitting space 1100, and the light emitting rate of the xth zone from the near light incident portion 111 is 1/(N-X + l), where N is a natural number and is greater than or equal to 2, and X is a natural number and is less than or equal to N. For example, in the present embodiment, a schematic structural diagram of the light guide surface 1120 is shown in fig. 13, the light guide surface 1120 is divided into 4 large regions, and the light extraction rates from the center to the outer edge of the light extraction space 1100 are 1/4, 1/3, 1/2 and 1 in sequence. The sizes of the large regions may be the same or different, as long as the above-described light extraction rate is achieved.

In a more specific embodiment, the light guide part 112 has a light guide film 1 forming the light guide surface 1120, the light guide film 1 forms regions with different light extraction rates, and the different light extraction rates can be realized by controlling parameters such as the size, i.e., the area, of each region. For example, in fig. 11 and 12, each large area may be equally divided into at least two small areas, the scattering film 1121 may be covered on a part of the small areas in each large area, and the number of the small areas covered with the scattering film may be gradually increased from the near light entrance portion 111 to the far light entrance portion 111, so that the light emission rate may be realized by controlling the number of the small areas having the scattering film in each large area.

In order to realize anti-glare, the distance between the covered cells of the light guide film 1 can be smaller than the rayleigh criterion, that is, smaller than the resolution distance of human eyes, so that the light emitting surface 1130 does not need to be subjected to secondary treatment, and the light emitting efficiency of the light guide pipe is prevented from being reduced.

Preferably, the scattering film 1121 covers the light guide portion 112 as a whole, and is configured to be divided into different regions according to the thickness or the internal medium. For example, the scattering film 1121 has a small thickness at the near light-entering portion 111 and a large thickness at the far light-entering portion 111, so that a light-emitting effect in which the light-emitting efficiency is uniformly changed is obtained.

For another embodiment of forming the light guide surface 1120, the light guide surface 1120 is also divided into N partitions from the center to the outer edge of the light-emitting space 1100, each partition has a different light-emitting rate, and the light-emitting rate increases from the center to the outer edge of the light-emitting space 1100.

Alternatively, in other embodiments, as shown in fig. 13 and 14, the light guide part 112 has partition grooves 1122 forming the N partitions, and a light fluid 1123 filled in the partition grooves 1122. And the optical fluid 1123 in the N zones has an increasing light output rate from the center to the outer edge of the light-emitting space 1100.

Among them, the optofluid 1123 may function as an optical waveguide, refract and reflect incident light emitted from the light incident portion 111, and uniformly emit light. The photo-fluid 1123 adopted by the embodiment of the invention is an ionic liquid which is composed of specific organic cations and inorganic anions, and the anions and the cations are mainly interacted through coulomb force. The common ionic compound has relatively small volume and symmetrical structure of positive and negative ions, and the bond energy between the positive and negative ions is relatively large, so that the melting point of the common ionic compound is very high (sodium chloride, the melting point is 801 ℃), and the common ionic compound is solid at room temperature. Different from common ionic compounds, the volume of anions and cations of the room-temperature ionic liquid is generally larger, the volume of cations is far larger than that of anions, and the ionic liquid has asymmetry and loose structure. This results in a low interaction force between the cations and anions, so that the ions are difficult to form a stable stacked crystal structure, and thus have a low melting point and will be in a liquid state at room temperature. The melting point of the ionic liquid is directly related to the size of coulomb force interaction between anions and cations of the ionic liquid, and the lower the coulomb force is, the lower the melting point is. However, not only the coulomb force exists in the liquid ionic liquid, but also the complex interaction between the anion and the cation of the ionic liquid makes the existence mode of the internal structure and the ion pair very complicated. The anions and cations in the ionic liquid coexist in a plurality of different ways, including single free ions, anion and cation pairs, charged ion clusters, non-uniform structures of about several nanometers, separated supramolecular clusters consisting of polar regions of ion networks formed by association of anions and cations, and non-polar regions generated by clustering of side chains (alkyl chains) of cations.

For example, the anion in the photopluid 1123 may be a tetrafluoroborate ion and the cation may be a quaternary ammonium ion. It is colorless and transparent, and has high light transmittance in visible light band. However, the refractive index is a traditional Chinese medicine parameter for researching the optical characteristics of the optical waveguide, and plays an important role in establishing the function of the optical waveguide of full emission. Specifically, the refractive index of the ionic liquid is influenced by the types of anions and cations. Specifically, the fixed anion is tetrafluoroborate ion, and the cations are all quaternary ammonium ions and have the structural formula shown in the specificationWherein the alkyl chain lengths of "R1, R2 and R3" are closely related to the refractive index.

In particular embodiments, the refractive index of the entire ionic liquid may be increased by increasing the length of the alkyl chains, thereby achieving a different refractive index for the optical fluid 1123. Specifically, the alkyl chain length of the cations "R1, R2, and R3" in the optical fluid 1123 near the light incident portion 111 may be smaller than that of the optical fluid 1123 near the outer edge of the light guide surface 1120, or the alkyl chain length may be gradually increased. In addition, the change in refractive index can also be achieved by increasing the concentration of the ionic liquid.

In other embodiments, as shown in fig. 15, the light-emitting unit 110 includes the light-emitting film 114 formed by a total reflection material and disposed on the light guide surface 1120, and the light-emitting space 1100 formed by the light-emitting space 110 is filled with the above-mentioned optical fluid 1123, where the optical fluid 1123 is an ionic liquid with a constant concentration and a uniform structure. The thickness of the light-emitting space 1100 is limited by the distance between the light-guiding surface 1120 and the light-emitting surface 1130, so that the light guide body with the thickness varying from the center to the outer edge of the light-emitting space 1100 is formed in the light-emitting space 1100 by the light 1123, and the purpose of uniformly emitting the light incident from the light-incident portion 111 by continuously transmitting the light is achieved. Wherein, the light-emitting film 114 can be coated with a Teflon coating layer, and the thickness of the coating layer can be 1-20 μm.

The shape of the light-emitting unit will be specifically described in detail.

In some embodiments of the light emitting unit, the light incident portion 111 is located at the periphery, the light guide portion 112 is located at the center inside the light incident portion 111, the bottom surface of the light emitting space 1100 is a light guide surface 1120, a separation film is disposed on the opposite surface, i.e., the light emitting surface 1130, the light guide portion 112 is connected between the light guide surface 1120 and the separation film, and the light emitting space 1100 is filled with a light fluid 1123. Wherein, the thickness of the light-emitting space 1100 from the center to the periphery is continuously reduced; the variation tendency makes the light guiding surface 1120 and the light emitting surface 1130 connected into a whole, the light guiding surface 1120 has a first variation curvature, and the light emitting surface 1130 has a second variation curvature. The first changing curvature has a tendency of changing from a small curvature, and the second changing material taking has a tendency of changing from a small curvature to a large curvature. Specifically, the first varying curvature has a first initial curvature K1 and a first end curvature K2, and the second varying curvature has a second initial curvature K3 and a second end curvature K4; wherein, K1> K2, K4> K3, K1> K4.

In some embodiments of the light emitting unit, the light guiding portion 112 is located at the periphery, the light incident portion 111 is located at the center inside the light guiding portion 112, the bottom surface of the light emitting space 1100 is a light guiding surface 1120, a separation film is disposed on a surface opposite to the light guiding surface 1120, the light guiding portion 112 is connected between the light guiding surface 1120 and the separation film, and the light emitting space 1100 is filled with a light fluid 1123. The thickness of the light-emitting space 1100 is continuously reduced from the center to the periphery, and the reduction trend is linear, that is, the bottom surface of the light-emitting space 1100, that is, the light guide surface 1120 is a plane.

In some embodiments of the light-emitting unit, the light-emitting space 1100 is formed by the light-guiding surface 1120, the light-emitting surface 1130 and the partition film in a closed manner, and the light-emitting space is vacuum during the formation, so that light loss can be reduced to the greatest extent.
