How can we judge whether the 0603 lamp is good or bad? LED lamp beads, Dongguan Hongjin Electronics Co., Ltd., 3528 SMD lamp beads, 3535UVC violet lamp beads

  0603 lamp beads belong to small power lamp beads, widely used in various home appliances, electronic watches, electronic desk calendars, electronic gifts, digital, communications, automotive electronics, lighting, electronic toys, traffic instructions, urban lighting engineering and other related production enterprises. Patch 0603 LED lamp beads have a total of red, yellow, white, blue, green, yellow, red and blue colors, and its brightness is 120 degrees. Here, Hongjin Electronics Xiaobian says how to judge whether the led lights are good or bad:

  1, the quality of the lamp: the quality of the lamp determines the quality of the chip. If you choose a small manufacturer to produce a poor lamp bead, the brightness of the lamp strip is relatively low, because the quality of the LED lamp bead light chip determines that the brightness of the LED lamp bead is not high, and those chips are 1-2 points. The inferior goods of money, the use of a problem comes to the leakage (dead lights), the characteristics of the products made by the genuine chip, is high brightness, stable performance. Expanding optoelectronics, all imported chips, such as Taiwan's Jingyuan. Fundamentally, the quality of the LED patch lamp is ensured.

2, heat dissipation: led patch lamp beads are also very important, if the heat dissipation conditions are not good, the lamp beads work at high temperatures for a long time, the light decay will be great, the lamp life will also be reduced.

  3, led patch lamp bead color temperature: the color temperature classification is as small as possible, so that a large number of led together when lighting will not be because the color temperature difference is too large, resulting in a greenish, some yellowish, some white.
