In recent years, most of the departments and local governments are promoting outdoor LED street lights, and the good news of the LED lighting industry continues, especially the large domestic demand market in China, which provides convenience for the development of LED lighting.When large sums of money are invested to promote outdoor LED street lights, are certain areas of technology mature and worth promoting? Is the use of outdoor LED street lights exposed to problems good or not? What problems need to be solved to promote LED lighting?In the field of general lighting, certain types of LED lamp technology have developed multiple mature? Led lighting is developed from low power. Compared with high-power lighting such as outdoor LED street lights, household and commercial indoor LED lights, the technology is relatively more mature and suitable for promotion. However, qualified products for indoor LED lighting are at least 40 yuan per lamp, which is higher than fluorescent energy-saving lamps.Not mastering high-end technology and expensive prices; lack of testing standards and uneven qualityRegarding outdoor LED street lights, the situation is not optimistic. The use of LED high-power integrated technology is not very mature and affects the lighting effect. Unlike other light sources, LEDs are “very afraid of heat”. If the heat dissipation system is not perfect, it will cause light decay and poor lighting effects. Generally, the lumens of the chip are the key factors that affect the luminous effect of the LED street lamp, but the high-end technology of the LED street lamp chip is abroad, and the cost of use is higher. At present, about 80% of domestic LED lamp chips are imported; the localization rate of indoor LED lamp chips is slightly higher.Although the one-time purchase cost of LED street lamps is high, it is worth promoting to save energy, but it should meet the quality requirements. Sodium lamp. "If we want to develop outdoor LED street lights, we need to continue to improve in certain areas?"The biggest problem is to accelerate the breakthrough of core technology. Wait, investment attraction in some places has broken the market rules." Resulting in low levels of expenditure. "In addition, there is currently no standard for product quality, power saving and other performance aspects. It is understood that for road lighting, the national guiding standard "Technical Specifications for Energy Saving of Road Tunnel Lighting Products" has been gradually introduced, but there is still a lack of uniform specifications in the quality inspection and evaluation of LED lights. "Without hard and unified standards, consumers lack judgment indicators when purchasing; instead, manufacturers' product quality is difficult to standardize, and it is easy to form a mess when bidding." some said.Experts believe that the specifications of chips and the specifications of mechanical parts should also be standardized, and quality control of LED lamps from the parts should be forced to force manufacturers who are aligned with the existing technology to improve product quality. The interface standards that are unified and cannot be unified should be improved by technology development. "Some experts also said that LED street lights are mainly used for municipal roads, and the legal regulatory department must strictly monitor the circulation system and bidding system to prevent "gray marketing" and "public relations marketing" to regulate the development of the LED industry.
The development of solar LED street lights has attracted high attention from all walks of life. With the development of solar led street lights getting hotter and hotter, people from all walks of life have paid more or less attention to it. According to statistics, 222,000 solar LED street lights were installed nationwide in 2009. In 2010, solar led street lamps developed at a high speed. Local governments in cities across the country actively promoted solar led street lamps, and solar led street lamps blossomed everywhere. However, with the vigorous promotion of solar led street lights, there are also many hidden dangers behind the huge economic benefits. Solar led street lights have been over-hyped and over-invested by some people, and unwittingly become a high-risk industry.This is firstly caused by blindly following the trend.Secondly, due to the high cost of street lights, the quality of the products varies, and the rate of extinction after installation , Follow-up maintenance costs make the company no profit or even loss.In order to change this situation, many solar led street light companies adopt the contract energy management mode, but the contract energy management mode requires solar led street light manufacturers to pay for the entire project cost themselves. The project payment is paid with the later electricity savings, and the payment cycle length It varies from shorter to 3 years and longer to more than 10 years. This directly tests the company's working capital and brings great risks. Solar LED street lights are a new lighting industry with huge potential. The government plays a leading role in the development of solar led street lights, gradually exploring the pros and cons of the new model, so that private capital has the opportunity to obtain profits; secondly, adopting a new model can break through the demonstration of solar LED street lamps. The capital bottleneck of large project investment and high risk guarantees the maximum interests and minimum risks of the three parties of production, consumption and finance. Only in this way can the solar LED market continue to be hot, and the promotion of energy-saving products will be marketized. The imperfections and deficiencies in the standards and application standards of solar LED street lamps and the problems in the current application can not be ignored. The most important solar energy is the quality and reliability of LED street lamp products directly determine the success or failure.
The future development trend of LED street lightsThe LED street lamp is a complex system composed of optics, heat and electronics. Although the life of the LED street lamp itself is long, if the drive circuit of the LED street lamp is not designed properly, it is said that the source device of poor quality is replaced, resulting in the overall drive circuit The life of the LED street lamp cannot be matched with the LED street lamp itself, which will affect the quality and life of the LED street lamp.Furthermore, the heat dissipation device of the LED street lamp is also very important. Once the operating temperature exceeds 100 ° C, if the heat dissipation system of the LED street lamp is not good enough, its own reliability will be affected. Of course, the early failure of LED lamp beads, local defects in assembly and transient phenomena will also cause the failure of LED street lamps. If proper and proper shunt protection measures are not taken, the failure of LED lamp beads will cause the entire string of LEDs to not light. , Which affects the overall lighting effect of led street lamps.LED street light is a complex system, involving various fields such as light, electricity, heat, machinery and so on. As far as drive power is concerned, it is mainly a matter of efficiency and reliability. First, the operating temperature of the driving power supply is very high. In this way, secondly, the traditional driving topology is complex and complex, including PFC, PWM isolation and constant current DC / DC three-level circuit. Reach a certain height, reduce the temperature of the drive power, and improve reliability. Low reliability, especially for sensitive devices such as electrolytic capacitors and optical coupling.Therefore, in the design process of LED street lights, the heat dissipation of LED street lights must be well taken into consideration. It is generally recommended that the operating temperature of LEDs should be below 100 ° C to avoid the reliability of LEDs being affected. Therefore, the designer of the LED drive circuit must carefully select the active or passive components in the circuit to ensure that it matches the life of the LED. For example, designers should ensure that electrolytic capacitors can be avoided, because such capacitors may produce leakage under long-term use conditions, resulting in shortened working life.
