How to decide the pros and cons of street light with solar panel and battery?

               Over the years, with the increasing popularity and promotion of street light with solar panel and battery, the use of LED lamps has become more widespread. The quality of street light with solar panel and battery will directly affect the use of solar street lamps.Judging the pros and cons of street light with solar panel and battery mainly depends on the following aspects: 

          Firstly,Look at the brightness of the street light with solar panel and battery. The power determines the brightness. Generally, the brightness of the street light with solar panel and battery with higher power will be much brighter than the power, and the price will be relatively higher.     

       Secondly,Look at the antistatic ability of the lamps.The street light with solar panel and battery with strong antistatic ability has a relatively long life. LED lights with an antistatic greater than 700V are usually used as LED lighting.

       Thirdly, understand the colloid of the street light with solar panel and battery. The colloid of ordinary LED lamps generally uses epoxy resin, and the high-quality LED light source generally has the functions of anti-ultraviolet and fireproofing agents. Because the lighting with anti-ultraviolet and fire retardant is relatively expensive, the high-quality street light with solar panel and battery is relatively less.

        Fourthly, understand the power supply of street light with solar panel and battery. Generally, the lamp is broken because the power supply is burnt out, so the power supply plays a vital role in the life of the entire LED lamp. Manufacturers will design different power supplies according to different design requirements, mainly divided into constant current power supply and constant voltage power supply.

        Fifthly, understand the radiator of the street light with solar panel and battery. The appearance of the luminaire can determine the effect of the radiator. If the exterior or interior of the luminaire is made of aluminum, the thermal effect of the luminaire will have a good balance check, because the temperature determines the service life of the street light with solar panel and battery,and the thermal effect can be effectively solved,extend the life of street light with solar panel and battery.     

       Sixthly,understand the leakage current of the street light with solar panel and battery. The LED is a unidirectional conductive illuminator. When a reverse current occurs, it can be judged as leakage. If the leakage is serious, the life of the LED lamp will decrease and the price will be relatively cheaper. LED lights mainly rely on chip lighting, and the price of different chips is not the same. If you want to choose a better quality chip, you can choose foreign imported products.

       Seventhly,Look at the illuminating angle of the street light with solar panel and battery. LEDs with different uses have different illumination angles. Nowadays, the common illumination angles on the market are 8°, 15°, 25°, 45°, 60°, 90°, 120°. According to the angle, it can be divided into narrow angle beam, medium beam and wide beam. For better light efficiency, a narrow-angle beam should be used, but depending on the needs, choose the lamp that suits you.

       Eightly, understand the wavelength of the street light with solar panel and battery.The wavelength of the luminaire determines the color of the light. The quality of the products produced by the well-known and qualified manufacturers is relatively high.

         Generally, the LED lamps with relatively pure color are produced by using the spectrophotometer, and the spectrophotometer is not produced. The LEDs will appear inconsistent wavelengths, and the colors will naturally be inconsistent.

         Ninthly,understand the size of the chip. With the side length as the unit of measurement, the quality of the large chip LED lamp is better than that of the small chip, and the price is naturally more expensive. The quality of the street light with solar panel and battery directly affects whether the solar street light can work normally. We hope that when you choose LED lamps, you can learn to identify the quality of the LED light source.
