Points of concern of led light

Points of concern of LED light

1. Beware of low-price traps. The price of LED light sources varies greatly. LEDs of the same color and brightness can vary several times in price. This gap is mainly reflected in the reliability and light attenuation of the LED, appearance process and other performance. Low-priced LEDs have smaller chip sizes, rough electrodes, poor materials (phosphor and glue), poor current resistance, poor temperature and humidity changes, fast light decay, and short life. Therefore, blindly pursuing low prices may not be worth the loss.

  2. Recognize relevant standards. From a safety perspective, products should comply with relevant international and national standards. As LED is a new product, China's national standards are lagging behind and only product qualification tests are provided. Therefore, international safety certification (such as GS, CE, UL, etc.) is the standard to measure the quality of LED lights. At the same time, there are not many manufacturers that have international safety certification and national product quality certification, so you need to carefully identify the authenticity of the certificate when purchasing. The prices of products with international safety certification are generally higher.

  3. Use constant current power supply for LED lights. The price of the resistance, capacitance, IC and other components of the LED drive power supply varies greatly. The design of the entire power supply and the rationality of the circuit itself will directly affect the quality of the product. Some driving power supplies are only constant voltage, not constant current, and LED lights must be constant current to better ensure quality and service life. Therefore, this point needs extra attention when purchasing, especially for high-power LED lights.
