Description
Technical field
The utility model is about a kind of lighting engineering, particularly about a kind of light-emitting device of using cooling base.
Background technology
Traditional lighting adopts fluorescent tube (Fluorescent Lamp) (or claim fluorescent lamp) as light source more, and fluorescent tube utilizes electric power discharge excitation mercury in argon gas or neon to produce ultraviolet ray, and makes phosphorus matter send visible fluorescence to throw light on.Change because the light source that this lighting engineering provides can present light and shade with AC power, the light source of this flicker can directly influence user's eyesight.And the fluorescent tube with mercury composition not only damages human body, and the fluorescent tube of putting aside as useless also can pollute environment.Simultaneously, use this lighting engineering and need install electronic type rectifier or high frequency points modulator, except toggle speed is slow, also have the high and high shortcoming of caloric value of power consumption.
Based on above-mentioned factor, industry begins research and development application light emitting diode (Light EmittingDiode, lighting engineering LED).Compare with the lighting engineering of fluorescent tube, light emitting diode has that volume is little, caloric value is low (heat radiation is few), power consumption low (low-voltage, low current starting), life-span long (more than 100,000 hours), reaction speed fast (but high-frequency operation), environmental protection (shatter-proof, shock-resistant be difficult for broken, discarded object is recyclable, pollution-free) but planar package becomes compact advantages such as product with easy exploiting.Therefore, new trend is to replace fluorescent tube as light source with LED at present.Relevant patented technology has TaiWan, China utility model patent certificate M286898 number, M285658 number and M284176 case etc.
TaiWan, China utility model patent certificate is for M286898 number a kind of LED sheet lighting, utilize the LED illumination tiles of single module sheet or, replace traditional power consumption is big, illuminance weak and illumination can decay tubular type light fixture or projection light fixture in conjunction with the LED illumination tiles more than a slice.
TaiWan, China utility model patent certificate is for M285658 number a kind of lighting that increases illumination, the optics lampshade that group is located at the lamp housing opening part is the transparent optical eyeglass, this inside and outside surface of optics lampshade all constitutes the spherical arc of depression or projection, and be provided with containing hole at inner face, be provided with the spherical arc of depression or projection at the bottom of this containing hole, LED inserts in this containing hole and makes this LED towards the lamp housing opening, promotes illumination and brightness.
TaiWan, China utility model patent certificate is for M284176 number a kind of intelligent LED light fixture, be provided with control module at circuit board, and provide the configuration switch of multiple setting pattern, the luminance signal that this control module receives the setting pattern and cooperates this optical sensor to receive, provide corresponding electric current to LED, can cooperate the light illumination mode of setting to adjust the brightness of light fixture according to the original illumination of surrounding environment whereby.
