Development opportunities and status quo of LED street lights

Development opportunities and status quo of LED street lights According to forecasts, this year will be a period of global LED outdoor lighting replacement tide, and the number of global LED street lights installations will double in the coming years. Nowadays, governments around the world have advocated energy-saving renovation projects that replace traditional street lamps with LED street lamps, and have advanced to second- and third-tier cities. The intervention of 'smart lighting' has strengthened the advantages of LED street lamps and enabled them to use the original LED energy-saving technology. More energy-saving -%, coupled with the help of EMC mode, has accelerated the process of popularization of LED street lights. Even so, its popularity has not been as expected, especially since this year's LED street lamp advancing speed is significantly lower than expected, and the growth rate has slowed down. Is it affected by objective factors such as the change of government and anti-corruption, or is it subject to subjective factors such as LED street lamp technology and market prices. Non-standard LED street lights * the biggest bottleneck. At present, road lighting is still dominated by high-pressure sodium lamps, and LED street lights have not really replaced it. From a technical point of view, compared to high-pressure sodium lamps, LEDs are even better. For example, the luminous efficiency of the whole lamp, LED street lamps can reach more than lm/W, and high-pressure sodium lamps, even with lamps and ballasts, *more It can only reach -lm/W. The luminous efficiency of LEDs has significantly exceeded that of high-pressure sodium lamps, and from the perspective of price and cost, LEDs are not much higher than high-pressure sodium lamps. Although from a technical perspective and market price point of view, LED street lamps are not inferior to high-pressure sodium lamps, but its popularization still needs a process. Specifically, it can be described from the following three aspects: 1. The luminous efficiency of LED street lamps is higher than that of high-pressure sodium lamps, which is only for technical reasons. In the market, the LED industry is currently in the early stages of development, and there are more poor companies than good companies. This part of the 'poor students' will cause the market to misunderstand LED street lights: 'LED street lights are not good.' Therefore, how to make people recognize and accept the quality of LED street lights still needs a process; second, as the LED era continues to accelerate development, companies gradually realize the importance of product quality, and continue to develop toward high quality. The quality of the overall market circulation products will be Improve; Third, the issue of standardization. The traditional high-pressure sodium lamp, in simple terms, is composed of three parts: a bulb, a ballast and a lamp housing. The bulb is the most easily broken part, and its life span is about one year. Even if it is broken, it is very convenient to replace. Because it is a standardized product, it can be replaced by any manufacturer's bulb. On the other hand, LED street lights have different product specifications from different manufacturers. The same manufacturer needs to be returned for later replacement or maintenance of products. Indirectly, LED street lights have become a monopoly-bound product by enterprises. The irregularity of products is the biggest bottleneck in the way of LED street lights, and the establishment of standardized standards has become an urgent need for industrial development. If LED street lights solve the above problems, then high-pressure sodium street lights can fade out of the market. In theory, the promotion of LED on roads should be faster than indoor lighting, but due to the inertia of road lighting in the market, and the above standardization problems, its popularization effect has not been as expected. 'But I believe that there is a **, street lights will be the spring of LED.' Liu Muqing expressed his hope for LED street lights to the reporter of 'New Century LED'.
