Litelsolar Pengyao's trick: LED light source looks good

Whether it is solar street light or city circuit lights, LED lamp heads are used today, so how to judge the quality of LED light source? litelsolar tip: LED light source looks good or not. 1. Look at the brightness of the lamps. Generally, those with high power will be much brighter than those with low power, and the natural price is relatively expensive. 2. Look at the anti-static ability of lamps and lanterns. Those with strong anti-static ability and long service life can usually be used for LED lighting if the anti-static ability is greater than 700V. 3. Understand the colloid of lamps The ordinary colloid is epoxy resin, and the LED with anti-ultraviolet and fire retardant is of high quality. Fourth, understand the lamp power supply According to the different requirements of the manufacturer, it can be divided into two types: constant current power supply and constant voltage power supply. No matter which one is, the power supply plays a central role in the service life of the entire lamp. If the lamp is broken, it is usually the power supply that has burned out. 5. Understand the lamp radiator The radiator can see the appearance of the lamp. If the built-in or external lamp is made of aluminum, it may solve the thermal effect of the lamp and prolong the service life of the lamp. 6. Understand the leakage current of lamps LED is a one-way conductive luminous body. If there is a reaction current, it will become leakage, and the life of large leakage will be short. Seven, look at the light-emitting angle of lamps and lanterns The light-emitting angles of different uses are different, and you should choose the one that suits you according to the actual situation.
