Most of the impact of LED companies on the Sino-US trade war can calmly deal with

On May 10, the US raised tariffs on US$200 billion of Chinese goods exported to the US from 10% to 25%. In this regard, China has also made a counterattack. Among them, the Ministry of Commerce of China announced that China will establish a list of unreliable entities. The Tariff Commission of the State Council also announced that starting from June 1st, it will impose additional levies on some of the goods originating in the United States in the list of approximately US$60 billion in imported goods. %, 20%, 10% tariffs.



According to the US taxation project, many LED lighting products are involved. After experiencing the trade turmoil and various uncertain market factors in 2018, LED companies have more or less increased risk prevention measures for their strategic plans for 2019 and beyond.
As of now, China and the United States have not reached an equal and mutually beneficial negotiation result, and there are still various uncertain factors in the future. How much impact the Sino-US trade war will have on LED companies depends on the degree to which companies rely on the United States. The market has sorted out some export companies and found that most companies can calmly respond to the impact of the Sino-US trade war and have formulated proactive countermeasures. In the future, they will pay more attention to the domestic market or markets that are less affected by the US tariffs.

RGB and white LED

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

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.

LED light emitting diode

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.
