Description
Technical field
The present invention relates to a kind of led lamp, but particularly relate to a kind of photocatalyst led lamp of sterilization.
Background technology
The application commodity of light emitting diode (Light Emitting Diode is called for short LED) are seen everywhere in life, mainly as purposes such as demonstration backlight and illuminations.And along with the light emitting diode industry develops further maturely, developed many except that as the illumination function, also can via optical excitation produce chemical reaction and reach have other secondary belong to usefulness product.Photocatalyst led lamp with sterilization, deodorizing and self-cleaning function promptly is an example wherein.
Consult Fig. 1, existing photocatalyst led lamp with sterilization, deodorizing and self-cleaning function comprises a substrate 11, a plurality of LED light lamp 121 and a case 13.
Each LED light lamp 121 has one and is arranged at lamp socket 124, on this substrate 11 and is arranged in this lamp socket 124 and light emitting diode 122 that can be luminous after power supply, and the transparent encapsulated layer 123 that coats this light emitting diode 122 and can supply light to penetrate.
This case 13 comprises a housing 131 that links and define jointly room that can ccontaining said LED light lamp 121 with this substrate 11, and one deck coats the photocatalyst film 132 of case 13 outer surfaces, and this photocatalyst film 132 is with titanium dioxide (TiO
2) be that main material constitutes, can when irradiation, inspire high-octane electron hole pair and the chemicals of airborne pollutant and stench are decomposed into carbon dioxide (CO
2) and the innocuous substance of water etc., reach sterilization, deodorization, remove mould, decompose effects such as dirt and self-cleaning.
This photocatalyst led lamp said light emitting diode 122 when through 11 pairs of these LED light lamps 121 of substrate electric energy being provided produces light, and the light of generation can be used as light source through this case 13 to the external world; And the light that said LED light lamp 121 produces is when passing the photocatalyst film 132 of this case 13; Photocatalyst film 132 inspires high-octane electron hole pair and can pollutant or chemicals be decomposed into harmless carbon dioxide and water; And then reach sterilization, deodorization, remove mould, decompose dirt, and the clean effect of oneself.
Though such photocatalyst led lamp can be reached as light source really, with effects such as sterilization, sterilization, deodorizing; But because the light that the light emitting diode 122 of LED light lamp 121 sends need pass the air of 13 of this transparent encapsulated layer 123, this LED light lamp 12 and cases; And the housing 131 of this case 13 could get into row photocatalyst reaction in the photocatalyst film 132; And weakened most through the energy that enters into the light of this photocatalyst film 132 behind these many media, cause effects such as sterilization, deodorization and not obvious.
In addition; The assembling manufacturing process of such photocatalyst led lamp is very complicated-must first light emitting diode 122 be packaged into LED light lamp 121; Make simultaneously in addition substrate 11, case 13, again substrate 11, case 13, LED light lamp 121 are assembled into complete photocatalyst led lamp-production, cost of manufacture also thereby higher relatively at last.
