How To Identify Solar Power Street Lamp Quality?

The application of solar energy not only solves the energy problem for mankind, but also protects nature. Solar power street lamps use solar energy as the energy source, clean and pollution-free, alleviating the electrical pressure in urban and rural areas. At the same time, it also avoids the unstable illumination and power failure caused by the unstable AC power. With the popularity of solar street lamps in countries around the world, the issue of how to purchase high-quality solar powered street lamps has become very important. Some unscrupulous merchants reduce product configuration and product quality for immediate benefit. Therefore, it is necessary for us to learn some knowledge to distinguish the quality of solar power street lamps.

First of all, what we need to understand is that the lamp holder of the solar power street lamp which is the LED light source. However, for the dazzling array of light sources on the market, many friends do not know how to distinguish its quality. Many illegal businesses use fake and inferior LED light sources to impersonate high-quality imported LED light sources, which greatly harms the interests of customers. So, how should we judge the light sources quality of solar powered street lamps? We can observe whether the LED light source has glare. If the street lamp produces glare, it will make people's eyes feel uncomfortable and reduce visibility, which is very dangerous. Second, consider the color temperature of the LED light source. Outdoor lighting is best to choose neutral light close to natural light, and the color temperature should not be too low or too high. The quality of LED chips is also very important. Low-quality LED chips will have very large light decay and a short service life.

The second is whether the battery is a special battery for energy storage. Many small companies now use the starting power source as an energy storage battery, which greatly damages the service life of road solar lights.To balance the relationship between the power of the load and the capacity of the battery, it is best that the depth of discharge per day is only 30% of the battery capacity, so that the battery can achieve the best service life. Lithium batteries are recommended for solar power street lamps. The energy and density of lithium batteries are relatively high compared to other batteries, several times that of lead-acid batteries. It has a long service life, is green and environmentally friendly, and is light in weight.

It is also necessary to check whether the pole of the solar powered street lamp is hot-dip galvanized spray or cold galvanized spray. The hot-dip galvanized pole still has coating in the cut, and the cold-dip galvanized pole has no coating in the cut. Hot-dip galvanized light poles generally have a lifespan of more than 20 years, while cold-galvanized light poles generally have a life span of about 1 year. After all, solar street lights are outdoor lamps, so it is best to choose hot-dip galvanized poles, which have a long service life and basically no maintenance in the later period.

When choosing the solar powered street lamp controller, you need to consider the following three points. First, the controller needs to have complete protection functions, such as overcharge and overdischarge protection. The second is to have light control, time control, intelligent sensing and other functions. The third is to choose a controller with low power consumption and high charging efficiency.

When purchasing solar powered street lights, look for a professional manufacturer, and you should also understand the specific configuration of the street lights. The accessories of solar power street lamps mainly include solar panels, solar batteries, controllers, light sources, light poles and other corresponding components. In addition to some of the accessories we mentioned above, we also need to identify the quality of other accessories.
