(Summary description)With the increasing popularity and promotion of solar street lights, the quality of solar street light sources will directly affect the use of solar street lights. Let me introduce to you how to judge the quality of the solar street light source. Judging the pros and cons of solar street light sources mainly depends on the following aspects: One: Look at the brightness of the lamps. The power determines the brightness. Generally, the brightness of the higher power LED lamp will be much brighter than the lower power LED lamp, and the price will be relatively higher. Two: Look at the antistatic ability of the lamps. The LED light source with strong antistatic ability has a relatively long life. Generally, LED lights with antistatic power greater than 700V can be used as LED lighting. Three: Understand the colloid of lamps and lanterns. The colloid of ordinary LED lights generally uses epoxy resin, and high-quality LED light sources generally have anti-ultraviolet and fire-retardant functions. Because the lighting with anti-ultraviolet and fire-retardant is relatively expensive, high-quality outdoor LED lighting is relatively expensive. less. Four: Understand the power supply of lamps and lanterns. Generally, the lamp is broken because the power supply is burned 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, which are mainly divided into constant current power supplies and constant voltage power supplies. Five: Understand the radiator of the lamp. The appearance of the luminaire can determine the effect of the radiator. If the external or internal of the luminaire is made of aluminum, it will have a good check and balance effect on the thermal effect of the luminaire, because the temperature determines the service life of the LED lamp bead, and solving the thermal effect can effectively Extend the service life of LED lamps. Six: Understand the leakage current of the lamps. The LED is a unidirectional conductive light-emitting body, and a reverse current 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 cheaper. LED lights mainly rely on chips to emit light, and different chips have different prices. If you want to choose better quality chips, you can choose imported products. Seven: Look at the light-emitting angle of the lamps. LEDs with different purposes have different light-emitting angles. The common light-emitting angles on the market are 8°, 15°, 25°, 45°, 60°, 90°, 120°. According to the angle, it can be divided into narrow beam, medium beam and wide beam. If you want to achieve For better luminous efficiency, narrow-angle beams should be used, but according to different needs, you should choose a lamp that suits you. Eighth: Know the wavelength of the lamps. The wavelength of the lamp determines the color of the light. The quality of the products produced by the well-known and qualified manufacturers are generally higher. Generally, they use the spectrophotometer to produce the LED lights with relatively pure colors, but do not use the spectrophotometer for production. The output LEDs will have inconsistent wavelengths, and the colors will naturally be inconsistent. Nine: Know the size of the chip. Taking 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 solar street light source directly affects whether the solar street light can work normally. I hope that when choosing solar street lights, you can learn to distinguish the quality of the solar street light source, don't be deceived by black-hearted businesses, and remember to consume rationally.
