For quality issues, friends often ask friends how to distinguish, how to buy, how to buy. Whether there are guarantees such as quality, Tianhui Optoelectronics has produced light -emitting diodes for 20 years, and quality is guaranteed in quality. 1. The quality of the lamp beads: the quality of the lamp bead determines the quality of the chip. The quality of LED lamp beads light-emitting chips determines that the brightness of LED lamp beads is not high, and those chips are inferior products with 1-2 cents. After a period of use The characteristics of the product are high brightness and stable performance. 2. Color temperature: The color temperature grading is as small as possible, so that when a large number of LEDs are lit together, it will not be too yellow because of the color temperature difference, which is a bit yellow. 3. Heating: If the heat dissipation conditions are not good, the lamp beads work at high temperature for a long time, the light decay will be very large, and the service life will be reduced. 4. Salaring: The brightness of the lamp beads is divided, and there is a luminous distribution or the intensity of the light. It is recommended to purchase LEDs, or based on light efficiency, highlighting products can save energy and long life. 5. Glossoms: The fluorescent powder should be stirred with glue and then on the chip. The quality of the glue affects light decay and color drift. The poor glue time will be yellow, and the light decay will increase. Good glue is jelly. glue. 6. fluorescent powder: white light beads are made of blue -light chip and yellow fluorescent powder. The fluorescent powder is mainly divided into aluminum acid and silicate. The performance of aluminate is better than silicate. Aluminum acid is YAG. YAG has stable performance, low light decay, and poor chemical stability of silicate itself, but the brightness is higher than YAG. Don't be fooled by the so -called high brightness, this is a big problem. The editor explains that the lamp beads are good or bad.
