The LED illumination namely is led lighting, LED is a kind of semiconductor solid luminescence device, it is to utilize the solid semiconductor chip as luminescent material, by carrier compound energy of emitting surplus occuring and cause photo emissions, directly sends red, yellow, blue, green, blue or green, orange, purple, white light in semiconductor.The LED illuminating product utilizes LED as the produced ligthing paraphernalia of light source exactly.
The LED luminous product has following advantage:
High energy-conservation: the energy-conservation energy is pollution-free to be environmental protection.Direct drive, the electric light power transfer is near 100% for super low-power consumption (single tube 0.03-0.06 watt), and the equal illumination effect is more energy-conservation more than 80% than conventional light source.
Life-span is long: led light source has person, and it is long-life lamp, means the lamp that never extinguishes.The solid cold light source, epoxy encapsulation does not have loosening part yet in the lamp body, do not have the easily shortcomings such as burning, heat deposition, light decay of filament light-emitting, can reach 60,000 to 100,000 hours service life, and is longer more than 10 times than the conventional light source life-span.
Changeable: led light source can utilize the red, green, blue principle of three primary colours, under computer technology control, make three kinds of colors have 256 grades of gray scales and arbitrarily mixing, can produce 256 * 256 * 256=16777216 kind color, form different photochromic combinations changeful, realize colourful dynamic change effect and various image.
Sharp environmental protection: environmental benefit is better, does not have ultraviolet ray and infrared ray in the spectrum, has not both had heat, does not also have radiation, and dazzle is little, and discarded object is recyclable, does not pollute not contain mercury element, and cold light source can safe touch, belongs to typical green illumination light source.
High-new point: compare with the illumination effect of conventional light source dullness, led light source is the low pressure microelectronic product, computer technology, the network communications technology, image processing techniques, embedded Control technology etc. have successfully been merged, so also be the digital information product, it is semiconductor photoelectric device " high-new point " technology, has online programming, infinite update, flexible and changeable characteristics.
At present, Chinese semiconductor lighting industry development is become better, and the development of extension chip enterprise is especially rapid, the encapsulation scope of the enterprise continues to continue to increase rapidly, the application of throwing light on obtains greater advance.The Chinese LED application product output value surpassed 30,000,000,000 yuan in 2007, had become application product production and the exported countrys the biggest in the world such as LED full color display, solar LED, Landscape Lighting, and emerging semiconductor lighting industry forms.Domesticly formed certain characteristic at lighting field, wherein outdoor lighting is with fastest developing speed, and existing upper hundred LED street lamp enterprises have also built tens model paths, but aspect the indoor universal illumination market aobvious backwardness the still.China semiconductor industry industry is strong greatly and not, and core competitiveness still awaits further lifting.
For the development of present stage LED lighting engineering, the heat conduction of LED and radiating treatment become the restriction point that the LED Lighting Industry burns the wind.In the existing LED lighting apparatus, because the design of heat conduction, radiator structure is unreasonable, can not loose the removing of heat very fast, that well the LED lamp is produced when working.
