Heat and reliability is LED street light popularity impact

Discovery
There are two practices LED light source, one kind is to use traditional small power LED for combination, general as much as hundreds of single or even hundreds of star power source design, complex. Another kind is to use power tube as the light source, price is more expensive. Two methods is inevitably will design and operation reliability heat as the main design considerations, many domestic application demonstration project in the government, really the market operation of engineering, the little abroad application example is more, but the biggest drawback is still reliability, the number and price, light lumens many engineering due to poor quality, LED not better showing the advantages of life. Also, from the point of view of costs, market, LED lighting source, its whether as a combined with solar energy, design on the need to take different routes, and not alone as a source for development will be able to complete the.

The LED device products applied to the street lamps, technology at the special requirements is mainly to combination LED light intensity and light Angle, in addition to design the star, a combination of LED light design should take the illuminate lamps and lanterns to face domain, consider mainly the effectiveness of the heat.

The LED street light and ordinary street light contrast advantage: the energy conservation, the environmental protection, easy and low voltage adapter, also can and solar system directly supporting, without additional inverter, and conversion process, can achieve maximum energy efficiency.

Inadequate: lighting Angle, not even smaller color, the colour developing index is low, optical, thermal design complex.

The lack of technology: the current technology of flux is not enough, and low efficiency, quality to guarantee.

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

The LED used in street lamps have congenital advantage also have disadvantages. The advantage is that: first, LED light source, if as point, reasonable design, to a great extent can directly solve traditional ball light source must rely on light emitting to solve the second take light and light loss problem; Second, the evenness controllable light irradiation, theoretically can do in target area even, this also can completely avoid traditional light source "the light bright" phenomenon the light in the waste; Third, color, such WenKeXuan in different situation in the application of increase efficiency and reduce cost is also one of the important ways; Fourth, there is a large space technology progress.

Disadvantages (influence factors of popularization and application street) : the current price is too high, low, the current equal flux intensity of illumination design LED light source of price equivalent to about 4 times of traditional light source (but in street lamp of product, total cost of light source is not high, so in engineering in the installation of the scale also raised the cost is too high, the application will not space or larger), in the civil to bear. The current design and manufacturing standards chaos, the damage ratio is high, the influence of the LED advantage. Life

Suggestion: uniform standard, improve quality stability LED, set up the market competition coordination organization and avoid vicious competition, the publicity of the quality idea, avoid LED by the influence of the bad example, want to let people from the thought LED is actually can accept achieve its long life, improve the advantages of the selection and use of the LED level.
