The LED lights have two kinds of methods, one kind is to use traditional small power LED for combination, general up to hundreds of single or even hundreds of single, power design complex. Another kind is made using high-powered tube illuminant, price is more expensive. Two methods are inevitably will design and operation reliability heat as the main design considerations, the domestic many applied in government demonstrative project, real market operation of engineering rarely, foreign this application example is more, but the biggest drawback is still reliability, the number and price, light lumen due to many engineering poor quality, not very LED long life better showing advantages. Also, from the cost, market Angle consideration, LED lighting source, whether its as used in combination with solar energy in design, need take different routes, and are not alone as a source for development will be able to complete the.

LED device products applied to the LED street lamps, technology at the special requirements is mainly to combination LED light intensity and luminous Angle to design, another star, because a combination ...
... of LED light design, to give consideration to illuminate surface domain need key consideration heat lamps and lanterns of effectiveness. Street lamps and ordinary LED the comparative advantage: energy-saving, environmental protection, easy and low voltage adapter, also can and solar system directly supporting, no extra inverter, and conversion process, can achieve maximum energy efficiency(energy efficient lighting). Inadequate: lighting Angle slants small, uneven, color colour developing index is low, optics, thermal design complex.

Technical deficiency: the current technology isn't enough, the flux too hard to ensure efficiency, quality.

Solutions: LED products used in street lamps need special design, also need special standard (with traditional light test data to evaluate LED light-source often not objective).

LED applied to have congenital advantage street has disadvantages. Advantage: first, LED as a point source, if the design is reasonable, largely can directly solve traditional spherical source must rely on light emitting the second take to solve problem, light and light loss Second, the evenness controllable light irradiation, theoretically can do exactly homogeneous in target area, this also can avoid traditional light "under the lamp light" phenomenon of light waste, Third, the color WenKeXuan, so the application in different situations, but also improve efficiency and reduce cost a important way, Fourth, there is a large space technology progress. Disadvantages (influence factors of lamps application) : current price also is too high, low, the same illuminance luminaire designed LED light-source price equivalent to about 4 times of traditional light lamps products (except in total cost, light part is not high, so the cost in engineering installation percentage improvement also won't too high, application space or larger), in the civilian to bear. The current design and manufacturing standards is chaotic, the damage ratio is high, influence LED life advantage. Suggestion: unified LED standard, improve quality stability, coordinated organization founded the market competition, avoid vicious competition, the publicity of quality concept, avoid LED by the influence of bad example, should let people from the thought LED is actually can accept the advantages of realizing its long life, improve the level of choice and use leds.from: cheap led lights
