The screen brightness of solar LED street lamps is unstable, which is mainly related to the lamp bead chip, drive power supply and radiator. Because the previous LED technology is not perfect and the manufacturer's manufacturing level cannot keep up, the product quality of the above parts cannot be guaranteed. However, with the development in recent years, LED technology has been very mature, and the screen brightness is rarely unstable. However, in order to ensure the reliability of the brightness of the street lamp screen you purchased, you should still pay more attention to the product quality of these three components:

1. LED lamp bead chip

Solar LED street lamp bead chip is a component that can directly reflect the actual effect of screen brightness. If the LED lamp bead chip product quality is not good, it will not only cause the actual effect of screen brightness is not good, but also interfere with the reliability of LED street lamp screen brightness. Therefore, street lamp manufacturers should choose LED lamp bead chips produced by brand manufacturers, and do not need to choose LED lamp beads labeled by small workshops as much as possible. Since brand manufacturers attach importance to word of mouth and service, and the production process is relatively mature, the product quality and quality must be guaranteed.

2. Drive power

The power of the solar LED street lamp should be matched with the power of the LED light source scientifically and reasonably. If their power is not matched reasonably, the lighting will be unstable naturally. In addition, we should also ensure the quality of the street lamp power supply, and choose the power supply produced by the brand manufacturers as far as possible.

3. Radiator

Because the LED chip has a large heat output, the LED street lamp head must be equipped with a radiator for use. Street lamp radiator is an important factor that interferes with the reliability of screen brightness. We also need to choose radiators produced by brand manufacturers. We have to admit that their radiators have higher heat dissipation efficiency and emit more heat at the same time, so the reliability of street lamp screen brightness is higher.

As long as users pay more attention to the above three parts of LED street lights when purchasing, they don't have to worry about the unstable screen brightness and poor lighting effect. Although some products are lower in price, price shrinkage means product quality shrinkage. Such products are very prone to uneven lighting, insufficient screen brightness and other problems, so we should not take advantage of small gains and suffer big losses.
