Wu Zhaohui: High-end LED brackets look at materials and structures
Before 2010, the core technology of LED brackets was mainly in the hands of Japanese and Taiwanese manufacturers. After 2010, a large number of domestic LED bracket manufacturers quickly emerged, and the technology has improved. However, due to excessive dependence on imports of materials and equipment, the market share of domestic single LED bracket manufacturers has always been within 10%.
"Ceramic brackets will become one of the main directions for the development of LED bracket technology." Wu Zhaohui, director of the technical department of Dongguan Kaixide Electronic Technology Co., Ltd. (hereinafter referred to as "Kay De"), said that with the COB packaging and ceramic preparation technology The pace of marketization has accelerated, and the field of LED stent technology has also expanded. At the same time, this also brings a new round of development opportunities for domestic stent manufacturers.
Low-end "price war"
"The price difference between the high-end LED bracket and the low-end bracket is almost 50%." Wu Zhaohui said. High-end LED brackets have always been the world of foreign manufacturers, but nowadays domestic companies can also produce LED brackets with strong heat dissipation, anti-yellowing, airtightness and outdoor waterproofing through imported materials and equipment. However, the price war on the current support is in full swing, and the market for high-end LED brackets is quite embarrassing.
First of all, from the material of the LED bracket, plastic as a key material, can be roughly divided into nozzle material, domestic material and imported material according to the quality division. Among them, the nozzle material is the secondary use of waste recycling, and no one will associate it with the high-end LED bracket. Domestic plastics are far away from foreign imported materials in terms of purity, performance stability, anti-yellowing, anti-ultraviolet, etc., if used for the production of low-end LED brackets are still applicable. "At present, most of the plastics for producing high-end LED brackets are imported from Japan, and the price is about 2-3 times that of domestic plastics." Wu Zhaohui revealed.
Secondly, high-end LED brackets require enterprises to have high-end manufacturing technology, including excellent product design, precise mold design and high-precision processing capabilities. The most important of these is that the "tools" for making LED brackets are high-end. At present, domestically produced equipment can only produce medium and low-end brackets, and the key technologies of high-end equipment are still in the hands of Taiwan, Japan and other foreign manufacturers. Wu Zhaohui said that taking injection molding equipment as an example, the price of mid-end equipment is about 500,000-600,000 yuan, and the high-end is about 1 million yuan.

Exhaust Fan, driven by the fan to rotate the air flow, so that indoor and outdoor air exchange of a class of air-conditioning appliances. Also known as ventilation fan. The purpose of the exhaust is to remove the indoor dirty air, adjust the temperature, humidity and sensory effects. Exhaust fans are widely used in homes and public places.
Exhaust fan, also known as negative pressure fan, negative pressure fan and so on. Is the use of air convection can make the room has been in a negative pressure state, the formation of a suction, a steady stream of outdoor air, and exhausted indoor hot air, so as to achieve ventilation and ventilation, cooling effect.
