When we buy LED street lights, how to choose a manufacturer? Many customers choose to trust middlemen, who not only give up high profits but also cannot find manufacturers to deal with after-sales problems. The LED street lamp is a kind of high-efficiency solid-state light source formed by semiconductor PN junction that can emit light with weak electric energy. Under a certain forward bias voltage and injection current, the holes injected into the P area and the electrons injected into the N area are in After being diffused into the active area, photons are emitted through radiation recombination, which directly converts electrical energy into light energy. LED street lamp manufacturers are a kind of solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Therefore, LED street lamps will become the best choice of the energy-saving transformation of road lighting. Some customers are cheated by wallet companies or small workshops at low prices, resulting in cutting corners. LED street lamp manufacturers are a kind of solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency, and long life. Therefore, LED street lamps will become the choice for energy-saving road lighting. However, some customers had to bear the losses themselves because they could not find a reliable supplier, and the delivery time was delayed repeatedly. Therefore, how to find a trustworthy Led Street Light Factory has become a concern of buyers.
You need to make sure that the company you provide is not a fully qualified led street light factory. Secondly, the led street light factory’s own products are not the core components of led street lights, and how many core components of solar lights are produced by the manufacturer. We need to confirm the above information. The direct and effective method is to inspect the factory personally. Personal experience is more effective than anything. Directly.
Manufacturers are also layered, with small family workshops, smaller processing plants, and small factories producing individual components and other components to assemble outside. And a trustworthy manufacturer must be a professional manufacturer with in-depth research on the overall led street light system. Therefore, it is necessary to judge whether the manufacturer is professional and trustworthy, which depends on whether the manufacturer has deep technical deposits for the entire solar system. The professional level of the manufacturer can be reflected in the following aspects:
1. Whether the experience of leading the street lighting business is more than three years;
2. Whether there is a professional technical team (the team size is guaranteed to be more than 3 people);
3. Whether the research on the configuration of the solar energy system is in-depth enough, whether the calculation process of the configuration can be demonstrated, how to obtain the constant of the configuration, and whether it has been verified by experiments;
Can we develop new products ourselves?
If you can do this, it can be regarded as a relatively professional manufacturer. In short, a manufacturer who can provide reasonable prices, good quality, and excellent after-sales service is a reliable manufacturer.
