the characteristics of high power LED and the comparison with other light source
high power LED as light source for lighting has the following advantages: 1)
Less power consumption, is 75 lm/w LED lighting is the same brightness of incandescent lamp power consumption reduced by 80%;
2) Long life: product life 50000 hours, 24 hours of continuous light available 7 years
3) Nanosecond response speed, the dynamic control of the brightness and color easy: it can realize dynamic change color and digital control
4) Design space is large, which can realize the fusion, and architecture to achieve the effect of didn't see the lights for the light.
5) Environmental protection: no harmful metallic mercury, no infrared and ultraviolet radiation.
6) Color: different wavelengths produce different colored light, bright saturated, no filter, red, green and blue color available control after form a variety of different colors, which can realize full color gradient and so on all sorts of color changing effect.
incandescent lamp, 5 mm LED compared with the life of Luxeon 1 w high power LED, high power LED on life has great advantages, and incandescent lamp and some other traditional light source in many technology promotion space is very small.

2, the application of high power LED underwater light
the quickening pace of urban construction, leisure square and green space has become a bright spot of the city park, represents a city people eager to return to nature. Water represents the spiritual, water features and fountains is an integral part of leisure square and green park, the demand for underwater lamp is quite large. The current color underwater lights are generally traditional PAR lights, produce all sorts of color require additional filter, greatly reduces the luminous efficiency. Product can photoelectric through study, under the red, green, blue light, the lamps and lanterns of traditional total luminous flux LED underwater light is 1 ~ 2 times, LED packaging technology determines the direction of light source is very strong, coupled with the LED light source volume is very small, and the ability to cooperate with all kinds of Angle of optical lens, these characteristics determine the traditional underwater lamp consumed power more than 13 times that of LED underwater light, thus LED underwater lamp, energy saving effect is very significant. In addition, the LED spectral distribution determines the color purity and saturation is unmatched by traditional PAR lamp, thus has a strong competitive advantage.
the LED packaging technology determines its light source sex is very strong, the following figure 1:

building glass in modern buildings are more and more big, more and more varieties, function is more and more complete. Construction on the building of glass are, types and the functions of application can be used as evaluation of modern buildings. Especially construction glass decorative performance, can say is protean, no construction glass, there would be no modern buildings. But because the glass can not only through the light and reflect light and absorb light of optical properties, and building the landscape lighting design of form a complete set into a pattern. How can through lights represent glass is the simple sense of beauty in the day? This is a question of common concern to landscape lighting designers. Product can photoelectric thinks, for large glass processing of modern architecture lighting, using 'architectural lighting' light-emitting devices, The light source) And construction, not only make the connotation deepening and expansion of lighting lamps and lanterns, and varied in form, let a person find everything new and fresh.
high power LED single high photosynthetic efficiency, unit volume small, the design is flexible, cooperate with the structure characteristics of light carrier, to a great extent and easy installation. For such construction provides a new lighting solution.

the semiconductor lighting industry is a vigorous future industry, packaging technology, cooling technology, optical technology, application technology and control technology unceasing enhancement, is to promote the industry to accelerate the development of a belongs to the future of LED lighting with the successful application of high power LED has come.
