1, beware of low-cost traps, LED light source prices vary greatly, the same color with the brightness of the LED, the price can be a difference of several times. This gap is mainly reflected in the LED reliability and light fade, appearance of technology and other performance. Low-cost LEDs have small chip sizes, rough electrodes, poor materials (phosphor powders and glues), poor resistance to current, temperature and humidity changes, fast light decay, and short life spans, so blind pursuit of low prices may outweigh gains. The

2. Recognize relevant standards. From the perspective of safety, products should comply with relevant international and national standards. Since LED is a new product, China's national standards lag behind and only provide product qualification tests. Therefore, the international safety certification (such as GS, CE, UL, etc.) is the standard for measuring the quality of LED lamps. At the same time, there are not many manufacturers that have international safety certification and national product quality certification. When purchasing, it is necessary to carefully identify the authenticity of the certificate. Products with international safety certification are generally higher in price. The

3, the use of constant current power LED lights, LED driver power supply resistance, capacitance, IC and other components prices vary greatly, the entire power supply used by the program and the rationality of the line itself design will directly affect the quality of the product. Some drive power supplies are only constant voltage and do not achieve constant current, while LED lamps must have constant current to better ensure quality and service life. Therefore, this requires extra attention when purchasing, especially for high-power LED lights. Package explanation Simply, the LED package is the process of encapsulating the LED package material into the LED lamp.

The general package of the LED(GU10 LED Spotlight manufacturer china) must go through the process of crystal expansion - solid crystal - bonding wire - gluing - drying - cutting - color separation and other process packaging materials Led's main packaging materials are: chip, gold wire, bracket, glue and other packaging equipment, crystal expansion equipment, solid crystal machine, wire bonding machine, dispenser, baking box, etc., are generally divided into fully automatic packaging equipment manual packaging equipment two Species.
