How to judge the pros and cons of solar street light source?

In our daily life, we often see solar street lights. Solar street lights are called green products because they do not pollute the environment. They use solar energy as electrical energy to provide road lighting at night. As long as there is sufficient sunlight, the lights can be turned on, but customers will first consider solar energy before purchasing solar street lights. The light source of the street light, because the quality of the light source will directly affect the use effect of the solar street light. So how to judge the pros and cons of solar street light sources?

1. Look at the brightness of the lamps

Power determines the brightness. Generally, the brightness of LED lights with higher power will be much brighter than those with lower power, and the price will be relatively higher.

2. Understand the colloid of lamps and lanterns

The colloid of ordinary LED lamps is generally made of epoxy resin, and high-quality LED light sources generally have the functions of anti-ultraviolet and fire-retardant agents. Because lamps with anti-ultraviolet and fire-retardant agents are relatively expensive, high-quality outdoor LED lighting is relatively rare.

3. Understand the wavelength of lamps

The wavelength of the lamp determines the color of the light, and it has a good reputation. Qualified manufacturers generally produce high-quality products. Generally, they use a spectrophotometer to produce LED lights with relatively pure colors, instead of using a spectrophotometer. The LEDs produced by the color meter will have inconsistent wavelengths, and the colors will naturally be inconsistent.

4. Understand the power supply of lamps and lanterns

Generally, the failure of lamps is because the power supply is burned out, so the power supply plays a crucial role in the life of the entire LED lamp. Manufacturers will design different power supplies according to different design requirements, mainly divided into two types: constant current power supply and constant voltage power supply.

5. Look at the antistatic ability of lamps and lanterns

LED light source with a strong anti-static ability and relatively long life. Generally, LED lamps with anti-static greater than 700V can be used as LED lighting.

6. Understand the radiator of lamps and lanterns

The appearance of the lamp can determine the effect of the radiator. If the external or built-in lamp is made of aluminum, it will have a good balance effect on the thermal effect of the lamp, because the temperature determines the service life of the LED lamp beads and solves the thermal effect. It can effectively prolong the service life of LED lamps.

7. Understand the leakage current of lamps and lanterns

LED is a unidirectionally conductive luminous body. If there is a reverse current, it can be judged as leakage. If the leakage is serious, the life of the LED lamp will be reduced, and the price will be relatively cheap. LED lights mainly rely on chips to emit light. Different chips have different prices. If you want to choose better quality chips, you can choose imported products.

8. Look at the lighting angle of the lamps

LEDs with different uses have different light-emitting angles. Now the more common lighting angles on the market are 8°.15°.25°.45°.60°.90°.120°. According to the angle, they can be divided into narrow-angle beams. Medium beams and wide beams, if you want to achieve For better light effect, narrow-angle beams should be used, but according to different needs, choose lamps that suit you.

9. Know the size of the chip

With the side length as the unit of measurement, the quality of large-chip LED lights is better than that of small chips, and the price is naturally more expensive.

The above methods of judging the pros and cons of solar street lights are shared here. In general, the quality of solar street lights directly affects whether solar street lights can work normally. I hope that when choosing solar street lights, Be able to learn to identify the quality of LED light sources, do not be deceived by unscrupulous merchants, and remember to consume rationally.
