In the popular application of SMD LED products, SMD LED lamp beads are widely used in all walks of life, whether it is home appliances electronic watches, electronic calendars, electronic gifts, digital, communications, automotive electronics, lighting, electronic toys, traffic instructions LED lighting beads are indispensable for related production enterprises such as urban lighting engineering. With the variety of products of 5050 LED lamp beads, many people always do not know how to judge LED lamp beads when purchasing 5050 lamp beads. Bad, the following LED lamp bead manufacturer Dongguan Hongjin Electronics for everyone to briefly introduce the three tricks to determine the quality of the patch LED lamp beads.

　　1, the quality of the lamp: the quality of the lamp determines the quality of the chip. If you choose a small brand manufacturer, the poor lamp bead, the brightness of the lamp strip is relatively low, because the quality of the LED lamp bead chip determines the brightness of the LED lamp bead is not high, those chips are 1-2 The inferior goods that divide the money, the leakage of electricity (dead light) is used when a problem is used. The characteristics of the products made by the genuine chip are high brightness and stable performance. The company selects high-quality high-quality chips, which fundamentally ensures the quality of the SMD LED lamp beads.

  2, heat dissipation: 2835 lamp beads are also very important, if the heat dissipation conditions are not good, the lamp beads work under high temperature for a long time, the light decay will be great, and the lamp life will be reduced.

  3, 3528 SMD lamp bead color temperature: the smaller the color temperature grading, the better, so that a large number of LEDs will not light up when the color temperature difference is too large, resulting in a yellowish, some yellowish, and some white.
