How to distinguish the quality of solar street lights?

As the country pays more and more attention to environmental protection, energy-saving and emission reduction, and green energy, all regions are looking for ways to reduce energy consumption and reduce damage to the environment. As a clean energy, solar energy is more and more favored by governments and people at all levels. So how do users choose solar street lights to identify their quality?

1. Look at the whole

First of all, the first thing we do is to look at the whole of the solar street light, whether the overall light is not smooth, whether there are any flaws, whether the welding is firm, etc. We also need to look at the power factor of the overall lamp. If the power factor is low, it means that the service life of the lamp bead is not long, and the circuit design is not very good, which will greatly reduce the service life of the lamp.

2. Look at the quality of the lamp head

Focus on the shell, lens, etc., look at its luminous frequency, followed by whether the luminous brightness of the lamp is translucent; if it looks a little dirty, then it is likely that the quality of the lamp is faulty. In addition, if it is a solar street light, it is necessary to check the quality of the battery; under normal circumstances, a good battery can continue to supply power for a week after being fully charged. Of course, this time is not fixed, and the power supply time may be relatively short in winter, after all, Sun exposure may not belong.

3. Look at the heat dissipation conditions

The heat dissipation of solar street lamps is very important. If the heat dissipation is good, the service life will be longer. If the heat dissipation is not good, the lamp will be deformed and even the lamp beads will be damaged. Moreover, when the lamp beads work at a high temperature, the light decay will be very large, so the service life of the lamp will be relatively short. So when you go to understand solar street lights, you must understand the heat dissipation conditions of solar street lights and whether they can meet your needs.

4. Look at the quality of lamp beads

The lamp beads in solar street light fixtures are also very important. We all know that the quality of the lamp beads determines the quality of the chips. If the lamp beads are broken, it will affect the entire lamp and even the entire street light. Therefore, when we understand solar street lights, we must also pay attention to the quality of lamp beads.

5. Look at power efficiency and light efficiency

Many people say that the light decay of solar street lights is more serious, in fact, it also depends on the quality. Good solar street light has small decay, high light efficiency and high brightness. The higher the power efficiency, the less power it consumes and the greater the output power. When purchasing solar street lights, you should also pay attention to the efficiency and light efficiency of the power supply, so that you can buy high-quality solar street lights.
