What are the shortcomings in the application of high-power LED street lights?

In the past few years, the street lamps used in outdoor road lighting were almost all traditional street lamps with high-pressure sodium lamps as the base. Nowadays, most of these traditional street lamps have been replaced by LED street lamps with many advantages. At present, more high-power LED street lights are used on urban roads. High-power LED street light refers to a street light with a single power greater than watts and using new semiconductors. Generally applicable to street lamp poles with heights of meters and above. Although it also has many advantages, there are still many shortcomings in application. Today, a small editor of LED street lamp manufacturers will tell you what are the deficiencies in the application of high-power LED street lamps.

1. High-power LED street lights have high color temperature. Generally, its color temperature is between K and K, and the light color is white light. Under the condition of its color temperature, people's vision will feel too cold, and at the same time, people's observation ability will be reduced when people are farsighted, and people will feel fatigue under the light for a long time.

2. The production cost of high-power LED street lights is too high. At present, the price of a high-power LED street lamp is about twice that of the same power high-pressure sodium lamp.

3. The service life of high-power LED street lights is not long. Because of its relatively high power, the LED chip generates more heat, and even if it uses a heat sink, its heat dissipation performance is not ideal, which affects its service life.

Fourth, the light decay is relatively large. The same is because of its poor heat dissipation conditions and more heat emitted by itself.

5. The light distribution problem of high-power LED street lamps. At present, the light distribution technology of high-power LED street lamps has been greatly developed. Some LED street lamp manufacturers have developed secondary light distribution systems instead of relying solely on chips. Arrangement to distribute light, but comprehensively, the light distribution cannot be completely reasonable.

VI. High-power LED street lamps lack a unified technical standard in terms of product specifications. There is currently no unified technical standard for the production of high-power LED street lamps. Each LED street lamp wholesale manufacturer produces its own products according to its own standards. It is difficult to be universal. In addition, the characteristics of the multi-chip assembly of high-power LED street lights make the chips and LED lamps bundled together, which is difficult to maintain, and the original products must be used for maintenance.

The above are the shortcomings in the application of high-power LED street lights summarized by the editor in practical applications. But the editor believes that with the advancement of human technology, these problems will definitely be solved by LED technology researchers in the future. At that time, high-power LED street lights may be truly popular, let us wait and see.
