Disclosure of Invention

The invention provides a photocatalyst optical fiber lamp, which realizes efficient and safe indoor illumination capable of purifying air, wherein one part of emitted light enters an indoor environment to play a role in illumination, and the other part of the emitted light is absorbed by a photocatalyst coated on a lampshade to be used for catalytically decomposing indoor harmful gas, and is particularly suitable for a deflagration risk scene.

The technical scheme of the invention is as follows:

a photocatalyst optical fiber lamp comprises a light source, a coupling device, a transmission optical fiber and an illumination module, wherein the coupling device couples light emitted by the light source to the transmission optical fiber and then emits the light into the illumination module;

the lamp shade is of an inner-outer double-layer structure, a staggered gas channel is arranged between the inner-layer lamp shade and the outer-layer lamp shade, and photocatalyst materials are coated on the inner surfaces of the inner-layer lamp shade and the outer-layer lamp shade.

The invention uses short wavelength laser light source or LED light source, the coupling device is a device for coupling the light emitted by the light source into the transmission optical fiber, the transmission optical fiber is used for transmitting the light in a total reflection mode inside along the path of the optical fiber, and the energy is transmitted to the lighting module, thereby realizing flexible transmission. The lighting module is a device integrating lighting and air purification; the light from the optical fiber is converted into white light through the fluorescent sheet module for illumination; the photocatalyst is a semiconductor material with a photocatalytic function coated on the lampshade, and can generate a strong catalytic degradation function under the action of ultraviolet light and visible light to effectively degrade toxic and harmful gases in the air and effectively kill various bacteria. The staggered gas channel on the lampshade is used for circulating indoor air and fully purifying the air.

The lampshade can be in various shapes, such as a round table shape with a large front end and a small back end. The output end of the transmission optical fiber is connected with the rear end of the lampshade, light with a certain solid angle emitted by the transmission optical fiber is converted into white light through the fluorescent sheet module for illumination, and the light with the rest solid angle reacts with photocatalyst on the lampshade to purify air.

In the invention, the inner and outer double-layer structure of the lampshade can have various forms, and the first form is as follows: the inner layer lampshade and the outer layer lampshade are composed of a plurality of lampshade sheets, the inner layer lampshade sheets and the outer layer lampshade sheets are arranged at intervals, edge parts of the inner layer lampshade sheets and the outer layer lampshade sheets are overlapped, and gaps between the inner layer lampshade sheets and gaps between the outer layer lampshade sheets form staggered gas channels.

The second form is: the inner layer lampshade and the outer layer lampshade are of an integral structure, through holes which are mutually staggered are uniformly formed in the inner layer lampshade and the outer layer lampshade, and the through holes in the inner layer lampshade and the outer layer lampshade form staggered gas channels.

The lamp shade of above-mentioned two kinds of forms all can reach ventilative but light-tight effect, and the gas is carried out the circulation exchange through the gas passage of dislocation on the lamp shade and the air of external environment.

Preferably, the first fluorescent sheet is of a circular ring-shaped structure, and the area of the second fluorescent sheet is larger than that of the circular structure of the circular hole in the middle of the first fluorescent sheet. The reason that the second fluorescent sheet is slightly larger than the middle vacant part of the first fluorescent sheet is to prevent the blue light from leaking.

The connecting shell be cylindrical, the one end of connecting shell can be dismantled fixedly with the lamp shade front end, and connecting shell front end and rear end install second fluorescence piece and first fluorescence piece respectively, the connecting shell lateral wall between two fluorescence pieces has the bleeder vent.

Because the air holes are additionally arranged on the fluorescent sheet module and matched with the gas channel on the lampshade, the gas circulation efficiency is increased. When the lighting module works, air enters the lampshade from the air holes of the connecting shell or the staggered gas channels on the lampshade, the air in the lampshade is heated to rise temperature, slowly escapes to the outside through the air holes of the connecting shell or the gas channels of the lampshade, and indoor air with lower relative temperature flows in from the air holes of the connecting shell for supplement, so that the indoor air forms microcirculation.
