Local governments only focus on price, not quality, causing confusion in the LED street light market

When the car is coming, the street light is a little brighter, and the street light is dimmed when the car leaves. Some foreign cities have begun to adopt this technology. At present, mainland enterprises may have reached such technical requirements, but it requires sensor control and large capital investment, so there is no example application. LED street light-9 At this stage, compared with previous years, LED street lights are technically nothing new. In addition, there are also many controversies in LED street lights in terms of light efficiency, cost performance, evaluation and other key indicators. . LED is a point light source, if the application is not good, it is prone to glare problems. Moreover, from the perspective of the entire industry chain, LED street lights involve radiators and drivers, and the cost of replacing all high-pressure sodium lamps may not be more economical. LED street lights have high technical requirements, and large-scale replacement still needs to be studied. In addition, the current indicators for evaluating road lighting use illuminance instead of brightness. Only when the light distribution reaches the bat-type light distribution, the illuminance can replace the brightness. The actual situation is because the brightness measurement instrument is expensive and the penetration rate is not high. Therefore, for convenience, illuminance is generally used instead of brightness. There are loopholes in the evaluation system, and the quality of LED street lights is difficult to guarantee. Enterprises also have their own views on the government's strong promotion of LED lighting renovation projects. The government's promotion and subsidies can solve the urgent needs of enterprises, but whether they can fundamentally save enterprises is another matter. Whether the products won in the government project are qualified can only be tested by time. The government can solve the symptoms but not the root cause, and excessive administrative intervention may make the LED industry become the second photovoltaic industry. At the same time, he also pointed out that in the face of such an impetuous market, companies need to clarify their own development direction, rather than being swayed by government support projects. Of course, government support is helpful to the LED industry and promotes the development of the industry from a macro perspective. But the current situation is that the local government only pays attention to price, not quality, and does not start from the perspective of whether it is affordable. The market is already cloudy, and government intervention without guidance will only add to the confusion.
