When the external electric energy is supplied to the epitaxial layer 32 through the two electrodes 34 and the transparent conductive layer 33 through the substrate 2, the transparent conductive layer 33 allows the current to horizontally and uniformly diffuse laterally through the epitaxial layer. 32, which in turn causes the 〇 Μ Μ layer 32 to convert electrical energy into light and emit it upward through the transparent conductive layer; in the first preferred embodiment, 'the wavelength of light emitted by the luminescent diode 3 The range is 1 〇〇 nanometer ~ 76 〇 nanometer in the range of ultraviolet to visible light.

The light from the light-emitting diode die 3 does not deflect and may go to the same - ancient A, in the direction of .+ # a J, in the first preferred embodiment 'the rhythm of the photocatalyst layer 4 Sound helmet. Λ . The effect of encapsulation is achieved by a drought of 20 nm to 5 um. 2 The light is generated by the photocatalytic LED lamp of the present invention. When the photodiode luminaire 3 is supplied with electric energy through the photodiode die 3, the illuminating diode 201222875 is generated. Since the photocatalyst layer 4 is directly formed on the light-emitting diode crystal grains 3, it can directly pass through the photocatalyst layer* and then to the outside without loss. At this time, the photocatalyst layer 4 is directly absorbed from the light-emitting diode. All of the light energy of the bulk crystal 3 excites a pair of high-energy electron holes, and the excited electron hole reacts with the pollutants in the air and releases energy to generate a photocatalytic reaction, which decomposes the pollutant into carbon dioxide (c〇 2) The water-based harmless substance 'has the function of sterilization, deodorization, mold removal and self-cleaning; and the light-emitting diode crystal raises the light that is emitted into the oxidation target. • When the transparent photocatalyst layer 4 is used, the light can be emitted from the point light source originally emitted from the photocatalyst layer 4 to a soft and uniform surface light source through a plurality of internal refractions and reflections, thereby achieving light source Requirements for use. It can be seen from the above description that the present invention achieves the purpose of packaging by directly forming the photocatalyst layer 4 of the light-emitting diode crystal grains 3, thereby simplifying the manufacturing process and reducing the production cost, and at the same time, the lamp itself emits light when it is activated. The light generated by the diode crystal 3 can be directly and completely entered into the photocatalyst layer 4 without loss, and the light energy can be fully utilized by the photocatalyst layer 4 to excite the energy electron hole pair and then the environment. The pollutants in the decomposition are decomposed into harmless substances mainly composed of carbon dioxide and water, which achieve the effects of sterilization, deodorization, mold removal, decomposition of dirt, and self-cleaning. As shown in FIG. 3, a second preferred embodiment of the LED lamp of the present invention is similar to the first preferred embodiment described above, except that the substrate 2 includes a plurality of layers formed on the top. Each of the installation slots 21 has two mounting faces 211 which are inclined at an angle and are fixed for the LED die 3 to be fixed. 7 201222875 曰, so that when the light-emitting diode crystal grains 3 fixed on the installation groove 21 emit light, the light-emitting diode crystal grains 3 can be emitted by the inclined installation surfaces 2u. The light can be dispersed at an angle of __, and the effective power is increased as a light source uniformity, and at the same time, the photocatalytic effect between the light emitted by the light-emitting diodes 3 and the photocatalyst layer 4 is enhanced. Further, the functions of sterilization, deodorization, and self-cleaning of the present invention are enhanced. In summary, the present invention mainly deposits the photocatalyst layer 4 by plasma chemical vapor deposition and completely encapsulates the light-emitting diode die 3 on the substrate 2 to achieve the purpose of packaging to relatively simplify the current photocatalyst. The production and assembly process of the light-emitting diode lamp can simultaneously and directly enter the photocatalyst layer 4 for photocatalytic action without loss, thereby achieving sterilization, deodorization and self-cleaning. The effect is effective to improve the shortcomings of the current photocatalytic LED lamp due to the fact that the light of the photocatalyst film entering the casing is substantially lower, and the effect of sterilization and deodorization is not obvious, and the invention directly uses the photocatalyst. The layer 4 is used as an encapsulation layer body, and the light emitted from the light-emitting diode die 3 can be emitted from the point light source to the surface light source without any additional cover, thereby effectively saving production cost, so the invention can be achieved. The purpose. However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention, All remain within the scope of the invention patent.
