Under the guidance of the country's strategic task of promoting the optimization and upgrading of the industrial structure and cultivating new industrial growth points, LED has become the development focus of various local governments, and local governments such as Dongguan, Huizhou, Foshan, Shenzhen, Dalian, Nanchang, Xiamen have formulated Industrial development strategy planning has set off a wave of LED investment in China. Guangdong, which accounts for nearly half of the total domestic LED output value, listed the semiconductor lighting (LED) industry as the three major strategic emerging industries in Guangdong in the "Several Opinions on Accelerating the Transformation of Economic Development Mode" released in May. one. The LED industry has formed a situation of competition among hundreds of people in Guangdong. Shenzhen, Dongguan, and Foshan have all listed the LED industry as a pillar industry development. The LED industry has shown a full-blown trend.

The rapid rise of domestic LED companies and the rapid expansion of production capacity are launching strategies to compete for the LED market. From Sanan Optoelectronics, a leading company in the domestic LED industry, to Silan Microelectronics, which has expanded its production capacity, to the half-way out of Dehao Runda, the LED industry boom has almost swept the entire industry. Because the overall level of domestic LED product technology is not high, domestic companies are generally small in scale. The technical strength is weak, the product grade is relatively low, the LED market is fiercely competitive, and related manufacturers are fighting for price wars. At the same time, there are also phenomena such as disorderly investment and vicious competition in the LED industry. Judging from the current domestic market dynamics and the distribution of the LED industry structure, there has been a serious problem of repeated investment.

In addition, some local governments intend to open the local market to local enterprises in the development of the economy, or to lock the local market by investing in the market, and local protectionism is on the rise. If this local administrative barrier is not broken, it will inevitably bring about the convergence of industrial projects between regions, directly increase the industrial bubble, and hinder the development of regional integration. Different regions must highlight different characteristics and avoid simple and repeated construction for short-term benefits, which will lead to vicious competition in the future.

In addition, China's LED lighting still has a series of other problems. For example, China currently does not have a national standard for LED lamps, only some local standards; my country's local LED lamps and lanterns are obviously insufficient in design and innovation. To solve these problems, the LED industry can develop healthier, and LED products can better meet the needs of the public. Market leadership is the foundation for the long-term and healthy development of the LED lighting industry. The government must guide and support policies, regulations, R&D investment, application demonstrations, and standards. Only with a nationwide game of chess and overall planning can the LED industry guide the sustainable and healthy development of the LED industry.

Indoor lighting faces double market pressure

None

On April 2, the National Standardization Management Committee issued an announcement announcing the postponement of the implementation of 13 national standards including the "Limited Values and Energy Efficiency Ratings of Unitary Air Conditioners".

The meaning of common specifications and models of LED patches

0603, 0805, 1210, 3528, 5050 refer to the size of surface mount SMD LEDs. For example, 0603 refers to a length of 0.06 inches and a width of 0.03 inches. But please note that the 3528 and 5050 units are metric. The following is a detailed introduction of these specifications:

It has proven useful! UV LED can kill 99.9% of coronaviruses in 30 seconds

Seoul Viosys and SETi announced that Vio LEDs UV LED technology successfully killed 99.9% of the new coronavirus (COVID-19) within 30 seconds. According to the news, the research team of Seoul Viosys and Korea University (Korea University) used the Violeds compound semiconductor technology in mass production for testing.

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.
