When it comes to the grievances and hatreds of white LEDs, we cannot fail to mention RGB and white LEDs. The two have the same goal in different ways. They all hope to achieve the effect of white light, but one is directly presented in white light, and the other is in red, green and blue. Mixed light; one said that the other party's purity was not enough and the price was too expensive, the other retorted that he was beautiful in color, and criticized the other party for being old and declining. I am afraid that such a war will not stop in the short term. However
How to distinguish the positive and negative poles of SMD LED lamp beads
2020-09-17
Many packages, like some 0603, 0805 and other SMD LEDs, will have a green "T" symbol on the bottom. One horizontal side of the "T" is the positive pole, and the other side is the negative pole. Some SMD LEDs will be marked with a silk screen similar to a triangle symbol, so the bottom side of the triangle is close to the positive pole, and the top corner is close to the negative pole. The lead of the light-emitting diode is generally longer at the anode and shorter at the cathode.

Light-emitting diodes are commonly used light-emitting devices that emit energy through the recombination of electrons and holes to emit light. They are widely used in the field of lighting. Light-emitting diodes can efficiently convert electrical energy into light energy. LED lamps and lanterns generally have the characteristics of long life, good lighting effect, and energy saving. Because of so many characteristics that are superior to other traditional lamps, they have a wide range of uses in modern society, such as lighting, flat panel displays, and medical devices.
The impact of the new coronavirus pneumonia epidemic on the LED industry chain
2020-04-14
The new coronavirus epidemic spread rapidly before the lunar new year. To control the epidemic, the government first announced the implementation of "closure" measures on several Hubei cities led by Wuhan, and then successively removed Beijing, Shanghai, Shenzhen and other provinces, counties and cities. Incorporated into closed management, and extended the Lunar New Year holiday, and did not officially resume work until February 10.
