the shortages in the solar led lamp market?
What are the current shortages in the solar led lamp market? Solar lamp manufacturers tell the truth.
When it comes to solar led lamps, we often talk about what advantages it has over traditional lamps. As for the existing problems, few people mention it. The first is to promote the development of the industry for the purpose of positive publicity. Secondly, combining the needs of the development of the times. So, today we will briefly talk about the disadvantages of solar led lights.
Solar led light
As a long-time practitioner in the solar led lighting industry, he has been promoting solar energy lighting manufacturers' energy-saving and environmental protection, no electricity bills, and convenient construction, etc. for the manufacturers of solar led lighting in the industry. However, the introduction was not sufficient and even the rhetoric concealed it. This article briefly summarizes the problems existing in the current development process of the solar lamp industry. Please refer to and correct the solar lamp users and professional practitioners.
As the main light source of solar LED lamps, LED lamps mainly have LED chip quality problems, heat dissipation problems, light distribution problems, packaging problems, power supply driving problems, and life problems of electronic components. Its main effects on solar led lighting systems include:
First of all, once the LED street lamp is damaged, it needs to be replaced as a whole, and on-site maintenance is difficult, but it is not as convenient as traditional light source replacement.
Secondly, the heat dissipation problem of the light source system of the solar led lamp system: the LED chip emits a lot of heat while emitting light, and the light efficiency of the LED decreases with the increase of the junction temperature. To be reduced by about 5%, and the life and light decay of LED chips will also be greatly affected. Therefore, the heat dissipation of the light source is a problem that needs to be considered. At present, the heat dissipation methods of solar led lamps mainly include: natural convection heat dissipation, forced heat dissipation by installing fans, heat pipe and loop heat pipe heat dissipation. The forced heat dissipation method by installing a fan has a complicated system and low reliability. The heat pipe and loop heat pipe heat dissipation methods have high costs. At present, the solar lamp system generally has low power and the solar lamp has outdoor night use, the heat dissipation surface is on the side, and the body size is limited. It is conducive to the advantages of natural convection heat dissipation of air, and the general choice is natural convection heat dissipation. At present, the main problem is that many solar led lamps recommended by many manufacturers are modified solar lamp caps, because the chip is enclosed in the lamp housing, which will have a very adverse effect on the heat dissipation of the light source.
Third, the light distribution problem of solar led lamps, led light is emitted by a few points of LED chips, and there are many light sources. Therefore, a secondary light distribution system needs to be set up. There are still many ways to go for the rationality and scientificity of light distribution .
Fourth, the relationship between the configuration of the solar led lighting system and the price. This is because at present there is no perfect national unified standard for the solar lighting system. Each manufacturer produces its own products according to their own standards. Not only can they not be interchangeable with each other, There is also a concept of unscrupulous companies stealing replacements and substituting good ones to harm the interests of consumers.

Finally, the system life of solar led lamps is confused with the life of led light sources, which confuses consumers. At present, the life of led chips can reach 50,000 hours, and the slightly better life has exceeded 100,000 hours, but the solar lamp system also includes batteries and solar lamps. Controllers, light poles, solar panels and other components, the life of each component is different, the key is the storage battery and solar light controller, currently better can reach more than three years, poor quality will not reach Two years. This will result in increased costs for customers to use the system. Therefore, customers must consider the life span of each component of the solar led lighting system.
In general, the main problems at present include the technical level and market environment. I believe that with the continuous in-depth research of technology and the continuous improvement of market rules and the continuous improvement of the national credit system, the solar led lamp market will be more reasonable and truly do Let our lives be more environmentally friendly and clean.
