When night falls, we don't feel the infinite darkness, but we will feel the beautiful city under the light. This is actually the function of various street lights and neon lights. They bring different colors of night to the city, and also make many people feel the deep warmth. The development of cities will inevitably lead to this situation. When the city develops to a certain stage, the road lighting will be greatly affected. At present, the price of street lights in China is not very high, in part because the city planning does not need so many street lights.
Although this is the case, the price of street lamps is not high, and it is not entirely because the development of urban road lighting no longer requires a large number of street lamps. The main reason is that the production technology of street lamps has been very mature, and manufacturers can produce street lamps on a large scale, so the price naturally drops. This is best explained by the law of commodity value. The total value of commodities has not changed, but after more production, the price of a single product must be reduced. In fact, manufacturers now produce a lot of products, but not all street lamps are low in price. LED street lamps are the best counterexample, but this is also because its production technology is not fully mature.
Different from conventional LED lamp, it uses low-voltage DC power supply, with high-efficiency white GaN based power blue LED and yellow synthesis, high efficiency, safety, energy saving, environmental protection, long service life, fast response led light source, and unique advantages of high color rendering index, which can be widely used in the road. The shell can be produced at a high temperature of 135 degrees and a low temperature of - 45 degrees.
In the final analysis, the price of street lamp is mainly due to the increase or decrease of production level, which can be seen from the situation of the industry. Now the whole industry can produce many kinds of street lights, such as LED street lights, high pole lights and so on. In addition, the improvement of the production process has greatly improved the production capacity, and the low price is also a reason.
Here, Xiaobian reminds us not to be greedy for low prices, but to have high-quality LED street lights, so as not to cause trouble for our future use.
