Precautions when purchasing led street lights

With the continuous advancement and development of science and technology, various street lamps have appeared on the market now, and led street lamps are one example of them. Following this, a large number of manufacturers have appeared in the market economy. Faced with a variety of lamps, what should we do when buying? Let's take a look at it.　　1. Luminous efficiency　　Luminous efficiency is a key factor affecting the energy-saving effect of led street lamps. Everyone knows that the higher the efficiency, the better the energy-saving and emission-reduction effects. Therefore, pay special attention to this point when purchasing. First look at the explanation of the luminous efficiency in the manual. At present, the luminous efficiency of the most advanced LED lamps in my country is 80LM/W. If there is no explanation in this regard, find the manufacturer and let them give themselves a detailed explanation.　　Second, weight　　 This type of street lamp will be heavier than ordinary street lamps, and the manufacturer is studying the weight, hoping to improve this heavy situation. I believe that in the future development, related manufacturers will do better and better. At present, the manufacturer has reduced from more than 30 kilograms to more than 10 kilograms now. It can be seen that they are doubling down on their efforts. 3. The quality of the heat dissipation function has a direct impact on the service life of the lamp. According to the current technology, the best is the needle-shaped heat dissipation technology, and it has been used by many manufacturers. In the future, there will be more manufacturers. Joined the industry. According to investigations, this street lamp has a service life of 10 years with good heat dissipation and proper maintenance. Therefore, heat dissipation is necessary, and you must pay attention to it when purchasing.　　Four. Light decay 　　 High-power lamps will have better light decay. If the luminous decay rate is as high as 80%, the lamp will almost be scrapped and has no usable value. Its service life is only a few months. Therefore, when purchasing, pay attention to light decay.　　 These are the precautions when purchasing led street lights. Only when you choose a good product can you benefit. If the solar street lamp is unqualified, it will not only be troublesome to replace, but also increase the cost.
At the same time, as the recent research of SRS shows, the benefits of improved productivity and firm performance can make implementing basic management practices worth it.
