Detailed Description

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

The first embodiment is as follows:

in order to solve the problem that all wall washing lamps in the prior art cannot be bent, the embodiment provides a wall washing lamp strip, please refer to fig. 1 and 2, wherein the wall washing lamp strip comprises a flexible lamp strip 1 and a flexible lamp housing 2 coated outside the flexible lamp strip 1; the flexible lamp strip 1 comprises a linear LED luminous element, at least the part corresponding to the LED luminous element in the flexible lamp shell 2 is a light-transmitting structure 21, and the flexible lamp shell 2 can be bent in the width direction and/or the height direction of the flexible lamp shell 2 along the length direction of the flexible lamp shell 2.

In this embodiment, the wall washing light bar includes the flexible light bar 1 that sends the light source to and the cladding is outside flexible light bar 1, protects flexible light bar 1, and carries out the flexible lamp body 2 that adjusts to the light-emitting effect. The flexible light bar 1 and the flexible lamp housing 2 respectively indicate that the light bar and the lamp housing are soft, and can be bent within an allowable range, and for a wall washing light bar, after the wall washing light bar is assembled, the bending directions of the flexible light bar 1 and the flexible lamp housing 2 are consistent, and when the wall washing light bar is bent, the flexible light bar 1 and the flexible lamp housing 2 are not bent in the same direction and are not damaged. The bending directions of the flexible light bar 1 and the flexible lamp housing 2 are bending along the length direction of the flexible lamp housing 2 and towards the width direction and/or the height direction of the flexible lamp housing 2, and the bending directions can be understood as three modes of horizontal bending, vertical bending or torsional bending.

In order to normally emit light, the light-transmitting structure 21 is arranged at the position, corresponding to the light-emitting member of the flexible lamp strip 1, on the flexible lamp housing 2, that is, the light emitted by the flexible lamp strip 1 can be emitted to the outside through the light-transmitting structure 21 on the flexible lamp housing 2. Light-transmitting structure 21 on flexible lamp body 2 can only set up the position that corresponds at the illuminating part of flexible lamp strip 1, also can set up more positions of flexible lamp body 2 into light-transmitting structure 21, can set up whole flexible lamp body 2 into light-transmitting structure 21 even. It should be noted that the light-transmitting structure 21 is a structure that can transmit light through a corresponding portion of the flexible lamp housing 2, and the corresponding portion of the light-transmitting structure is not limited to be transparent as long as the light can transmit. The light that flexible lamp strip 1 was emergent can also adjust light via the light-transmitting structure 21 on the flexible lamp body 2, can adjust parameters such as direction, intensity, colour gamut of light.

In some embodiments, the light-transmissive structure 21 and the non-light-transmissive structure 21 portions of the flexible lamp envelope 2 are formed by extrusion or overmolding. The light-transmitting part and the non-light-transmitting part of the flexible lamp housing 2 can be integrated, and the flexible lamp housing 2 can be formed by extrusion or injection molding. The connection between the light-transmitting structure 21 and the non-light-transmitting structure 21 of the flexible lamp envelope 2 is an intimate contact, which may be directly formed by extrusion or two-shot injection.

In some embodiments, the flexible lamp housing 2 has embedded therein connection wires for electrical connection of the flexible light bar 1. The light source on the flexible light bar 1 is an LED chip, and the LED chips are electrically connected with each other and can be realized through a packaging structure of the flexible light bar 1, namely a circuit board; if there are other connecting wires, for example, the connecting wires between the wall washing lamp strips, or the power lines of the flexible lamp strips 1, etc. in consideration of the length of the product, the connecting wires can be embedded in the flexible lamp housing 2.

In some embodiments, the flexible lamp housing 2 comprises an outer lamp housing and an inner lamp housing nested therein, and the connection line is embedded between the inner lamp housing and the outer lamp housing. The flexible lamp shell 2 can be of an inner-outer double-layer structure, and can be formed by extrusion or double-material injection molding between the inner layer and the outer layer. And the connecting wire can be embedded between the inner layer and the outer layer.

The flexible lamp strip 1 is wrapped in the flexible lamp shell 2, and the connection relation between the flexible lamp strip 1 and the flexible lamp shell 2 is fixed after the wall washing lamp strip is formed. Of course, the fixing manner between the two can be changed, i.e. the fixing connection can be detachable, and also can be directly solidified.

Because of the strip-shaped characteristic of the wall washing light bar, the flexible light bar 1 used as the light source is specifically a linear light emitting element, wherein the linear setting represents the light emitted by the flexible light bar 1 and is a line along the extending direction of the light bar, of course, the line is determined according to the current actual shape of the light bar, and if the light bar is straight at this time, the line formed by the light emitting element is a straight line; if the current actual form of the light bar is bent, the line formed by the light-emitting piece can be a curve or a broken line according to different bending conditions.

The illuminating element included in the flexible light bar 1 is an energized LED chip, and the light source for illuminating itself is an energized LED chip. Specifically, an optional flexible light bar 1 has a structure that an LED light emitting element in the flexible light bar 1 includes a flexible circuit board 111, LED chips and a packaging layer 112, the LED chips are arranged in a linear manner and are inversely mounted on the flexible circuit board 111, the packaging layer 112 covers the LED chips along the extending direction of the LED chips, and the packaging layer 112 above each LED chip is continuous. Referring to fig. 3, the light emitted from the flexible light bar 1 is linear and continuous, has good integrity, and can be bent within an allowable range.

The LED bead 122 may be formed by only an LED chip, or may be a package of the LED chip, which includes the LED chip itself, and fluorescent glue packaged on the LED chip.

In order to realize the bendable characteristic of the flexible light bar 1, the PCB boards 121 are connected by flexible wires 124. The flexible wire 124 can be bent at will within an allowable range, and the bending direction of the flexible wire can be bent along the length direction of the flexible light bar 1 to the width direction and/or the height direction of the flexible light bar.
