Description
[technical field]
The utility model relates to a kind of white light LED lighting device, or rather, relates to a kind of white light LED lighting device with self-cleaning function.
[background technology]
Development and maturation along with the LED technology, the performance index of LED increase substantially day by day, the light efficiency of white light LEDs has has met or exceeded the light efficiency level of ordinary incandescent lamp at present, and luminous flux is also increasing considerably, and makes LED obtain using widely at lighting field.LED compare with the energy-saving lighting lamp of general photo-voltaic power supply adapted have the life-span long, heating is low, not fragile, power consumption is little and more energy-conservation outstanding advantage, people it be described as 21 century replace fluorescent lamps and incandescent lamp the 4th generation lighting source.
Having occurred in the market with the white light LEDs is the lighting device of illuminating source, such as street lamp, Tunnel Lamp, flood light or floodlight etc.These are the use of the lighting device of illuminating source with LED, reduce the consumption to electric energy to a great extent.But, because these lighting devices are mainly used out of doors, pollutions such as oil gas, organic steam, dust are arranged, make the light of lighting device export the decline that has to a certain degree.Therefore, need regular illumination apparatus to clean, yet, clean lighting device in public places, not only to expend a large amount of manpower and materials and financial resources, live normally but also may influence people, extremely inconvenient.
[utility model content]
Technical problem to be solved in the utility model is to overcome above-mentioned defective, and a kind of white light LED lighting device with self-cleaning function is provided.
The utility model is achieved through the following technical solutions: a kind of white light LED lighting device, comprise shell, white LED light source and light-emitting plate, described light-emitting plate is enclosed described white light LEDs in the receiving space of described shell, it is characterized in that: also be provided with at least one ultraviolet source in the described white light LED lighting device, the side that described light-emitting plate is exposed to the lighting device outside is provided with one deck photocatalyst material, described ultraviolet source is provided with towards described light-emitting plate direction, the described photocatalyst material of the UV-irradiation that this ultraviolet source sends.
Described photocatalyst is Nano titanium dioxide, titanium nitride or their mixture.
The thickness of described photocatalyst layer is the 0.3-0.7 micron.
