It is generally believed that the main reasons why LED street lamps cannot be replaced on a large scale include two aspects. One is the quality of the LED street lamps themselves, and the other is the cost of the LED street lamps. The current quality problems of LED street lamps are mainly reflected in total luminous flux, light efficiency, light decay, heat dissipation, color temperature, light distribution, stability, consistency, drive power and other parts quality life. The cost of LED street lights is a few times to several tens of times different from traditional street lights. The current advantages of LED streetlights are energy saving, long theoretical life, and environmental protection. Today, the promotion of green environmental protection in the world is very dazzling, and has received support from the government and industry.
Bottleneck resolution is only a matter of time
Governments have increased their investment and support for LED industry funds. In the first half of China, the investment in the LED industry amounted to 20 billion yuan. The high investment of government enterprises in research and production will effectively improve the quality of LED products and reduce the cost of LED products. In December 2009, Cree white LED achieved 186lm/W of laboratory light efficiency, and the continuous improvement of LED chip efficiency made the energy saving advantage of LED products more prominent. In the future, LED street lamps will adopt new materials and new technologies. The overall quality of LED street lamps, including light efficiency, light decay, heat dissipation, color temperature, light distribution, consistency, stability, and drive source, will also be well resolved. At the same time, technological advancement and large-scale mass production will effectively reduce the cost of LED street lamps, and the bottlenecks of LED street lamps are gradually solved.
On-demand customization is possible
On-demand customization is to provide the best and most suitable customized products according to different needs. Since the street lamps are suitable for different environments, the requirements for street lamps are different under different conditions of time, place and climate. When the LED street lamp industry matures, LED street lamp companies can provide corresponding LED street lamp products according to different needs. In the end, we can provide the best street lighting solution based on the information provided by the customer. Major countries and regions, including China, the United States, Japan, Taiwan, and South Korea, are setting industry standards for LED street lamps. The implementation of LED street lamp industry standards will also enable enterprises to develop and produce LED street lamps with better basis and guarantee.
Provides new streetlight demand research topics
It is necessary to study the kind of light on the road in different environments. LED street lights Due to the particularity of the light source, it is theoretically possible to make LED street lights of any color. In the different road conditions, what color and brightness are most suitable, there is no authoritative scientific saying. After installing LED street lights in Foshan, some people reported that the road surface was darker than before. The main reason is that LED street lights have good color reproduction, making the black road surface look darker than before. It has also been reported that 99% of owners have better results than high-pressure sodium lamps after installing LED street lights on certain road sections. The effects of different road conditions reflect a great difference. The government or industry can organize experts to systematically study the demand for light in different environmental conditions such as altitude, region, climate, time, and object of use, and obtain an optimal solution. For example, the light demand in different environments, the color can be white, yellow, or even any color such as red, green, blue, etc., including the total luminous flux of light, the need for light distribution, and the like. After these research results form a huge database, LED street light companies can provide corresponding street lights according to specific needs. It is even possible to finally achieve an LED street light through an automatic adjustment system that can emit different colors of light as required.
Another advantage that intelligent control systems cannot match traditional street lights
LED street light sources are different from traditional light sources. From some performance perspectives, LEDs are electronic components that can be intelligently controlled by ICs. At present, there is an intelligent LED street lamp system that intelligently and steplessly controls the brightness of LED lighting. The current intelligent system is mainly capable of controlling the brightness of the LED street lamp according to the road condition, thereby increasing the service life of the LED street lamp and saving energy. For example, the LED street light intelligent control system invented by the Institute of Computing Technology of the Chinese Academy of Sciences can achieve such an effect. The intelligent control device developed includes: a moving image sensor component for detecting whether there is a moving object on the road surface, and detecting the detected object. The information is transmitted to the microprocessor; the microprocessor is configured to generate, according to the detection information, a control instruction indicating that the LED street light is preset for a preset time length, and transmit the control command to the street light switch control interface; the street light switch control interface is configured to The control command lights the LED street light for a preset length of time. The intelligent control device further includes a communication component for transmitting and receiving information, the moving image sensor component is further configured to detect a moving direction of the moving object, and the microprocessor is further configured to generate a status message according to the moving direction to move the LED in the moving direction The street light lights up in advance. In the future, it is possible to automatically adjust the brightness, color, and angle lights according to different environments, and also monitor the use status of the lamps in real time to achieve intelligent control to achieve optimal results.
Will replace traditional street lights
The advantages of LED street lamps are numerous, and their advantages of energy saving and environmental protection are unmatched by traditional street lamps. After the quality of LED street lamps is mature, the advantages of green environmental protection and energy conservation will be more prominent. The LED industry is one of the most promising industries. The current technology has progressed faster than many people imagine, and industry standards are also being actively developed. When the quality of LED street lamps is stable, the long life of LED street lamps can be intelligently controlled and the cost will be greatly reduced to an acceptable level, which will eventually replace traditional street lamps.
