Changguang Semiconductor: The commercial value of COB in the field of downlights and spotlights has been highlighted
A Aluminum Stranded Conductor(AAC)is a bare conductor
(non-insulated conductor) applicable
for electrical power transmission in modern overhead power line with various voltage levels. It has cost and
weight advantages while comparing to copper wires and cables. And it is as
simple as installing copper wires. We have common aluminum conductor, rare earth aluminum stranded conductor with both single layer or multi layer
construction.

Unlike ordinary SMD packaged devices, the COB surface light source bracket is non-standard, and the design of the bracket is directly related to the heat dissipation and light efficiency of the product. In the field of COB device design, the design of the bracket directly affects the life and technology of the product. index. The traditional COB product, the chip and the heat-dissipating aluminum plate have a layer of thermal conductive adhesive, which is not conducive to the heat dissipation of the chip, and the light effect is not ideal. The COB surface light source product directly places the chip on the aluminum plate, and the heat dissipation structure design is more reasonable. The light distribution design is more reasonable and the light extraction efficiency is higher.
Compared with high-power and medium- and small-power LED light source devices, COB surface light sources have been highly competitive in terms of heat dissipation and light efficiency. At present, the most important factor limiting the development of COB surface light sources is that product prices are still relatively high.
Long Wei believes that the current price of COB surface light source and medium and small power LED light source devices is relatively close in the application of LED downlights and LED spotlights. It has already had great commercial value, and this part of the market will be launched first.
It is understood that Changguang has invested a total of 800 million yuan in lighting production base construction projects in Wuhan, and has already completed a phase of investment of 200 million yuan. According to Changguang's calculation, after the project is put into production, the output value can reach 2 billion yuan.
Profile of Changguang Semiconductor: Shenzhen Changguang Semiconductor Lighting Technology Co., Ltd. was established by Wuhan Changjiang Communication Industry Group Co., Ltd. and Wuhan Economic Development Investment (Group) Co., Ltd. to develop high-end COB surface light source and LED lighting products. , production and sales of semiconductor light source suppliers.
Changguang has been engaged in the research and development of COB surface light sources since 2008 and started mass production in 2011. In the first half of 2012, the monthly output of Changguang COB surface light source was between 30,000 and 40,000 pieces, and the mass production efficiency was between 120-130 lm/W. The highest luminous efficiency in the laboratory exceeded 150 lm/W.
