In the short term LED and traditional electric light source will complement each other

All the discussion about the new light source eventually we focus in efficient and energy saving, a survey shows that the current global lighting, efficient lighting can realize the target of energy saving about 40%. Lighting in LED, high pressure sodium lamp, electrodeless lamp, metal halide lamp in energy saving and smooth effect are in progress, a variety of light sources according to its own characteristics, application fields of emphasis, such as high pressure sodium lamp used for road and tunnel lighting, metal halide lamps used for plant (high power) and shops lighting (low power). LED with its own advantages, in the indoor and outdoor lighting have good performance, is the first choice to achieve energy-efficient lighting. A series of consistent light effect, price, color LED and color, cooling technology made no further breakthrough, how LED and complementary development of the traditional lamp; the next few years will be the focus of the industry.

LED for road lighting, and high pressure sodium lamp compared with the development of the industry is still controversial, LED chip technology, LED light effect and color has been significantly improved. When the color temperature of LED is 5000~6700K, the luminous efficiency reaches 60~90lm/W, and the color rendering index is about 60~80., which is much higher than that of the high pressure sodium lamp. However, the efficiency of high pressure sodium lamp also increased, but the magnitude of the increase is far less than the LED lamp, but its visual effect is still higher than the middle of the LED light. High pressure sodium lamp has gone through decades of development, improve the performance of small space, the future LED needs to consider how to performance in road lighting and the price is better than that of high pressure sodium lamp, high pressure sodium lamp has gradually lost its advantages in the field of road lighting.

From the electrodeless lamp industry technology and product application scope to analysis can be seen between the electrodeless lamp 80w-300w the most popular market, especially the application of industrial lighting and road lighting up, the energy saving effect, high price by the market certainly. Electrodeless lamp light source in the field of general lighting than the performance of the LED better. The deficiency is from the long-term development, although you can achieve the 90lm/w luminous efficiency before the electrodeless lamp, but to enhance the space limitation of luminescent material and luminescent principle, failed to show signs of a breakthrough.

Quartz in industrial and commercial lighting metal halide lamp and ceramic halide lamp at present good color has done 80-90, color stability, the luminous efficiency of 80-90Lm/w, the average life of 6000 hours or more, life is very small. Compared with the traditional light source, the high cost is still difficult to promote the application of LED. Such as LED in the replacement of the same amount of 70W halogen lamp light when the total cost is too high, the advantage is not obvious.

LED electrodeless lamp and metal halide lamp in small power lighting and focus lighting is incomparable, it can be very light from the principle and structure of the limitations brought by (power, volume) reflected; in the background lighting, decorative lighting, small power saving effect, electrodeless the lamp is slightly inferior. In general high power lighting gold halogen lamp and electrodeless lamp with low fever, no glare, no flicker, soft light characteristics such as a stroke above this point, has been reflected in the application market. It can be seen that LED and electrodeless lamp and metal halide lamp are complementary in the field of general lighting applications. LED's outstanding characteristics and technological progress will play a more important role in directional lighting. However, no matter in high power or low power, the problem of LED lamp light color inconsistency is still a big problem.

In future in the field of general lighting, LED and application of electrodeless lamp and metal halide lamp is complement each other, they play their important role in different fields. LED related technology is developing rapidly, the government and enterprises are also actively promoting its application, which will accelerate the development of the industry, the future should have a broader application space. LED should be based on the improvement of its main performance, in the field of lighting in the rational application.
