[Text / high-tech LED reporter Gao Jinyu] On November 26, 2013, Gaogong LED Lighting Exhibition was grandly opened at the Poly World Trade Expo Center in Guangzhou. The ceramic expert Planck was present with a variety of products.
With the rise of LED lighting power, ceramic materials are used by more and more manufacturers in the LED field for their superior performance. For example, sapphire, silicon carbide, and zinc oxide are ceramic materials, and phosphors are ceramic materials. There is also a ceramic substrate for heat dissipation.
The heat dissipation of power LEDs has always been a bottleneck. Because most of the LED electrical energy conversion is converted to thermal energy, the device lifetime is drastically attenuated. The high-power LEDs and LED lamps currently used basically solder the LED light source on the aluminum substrate, and the aluminum substrate is bonded to the aluminum heat sink through the thermal conductive adhesive. Because the thermal resistance of the aluminum substrate and the thermal conductive adhesive is large, the light effect and the life of the LED are affected; and the ceramic film forming technology does not need the aluminum substrate and the thermal conductive adhesive, which completely solves the problems of large thermal resistance and poor heat dissipation. The luminaire thus produced has a small thermal resistance and a small temperature rise, which greatly extends the life of the LED luminaire and saves costs.
Planck is an incubator of the National University Science Park of Zhejiang University. The ceramic film-forming technology, ceramic film-forming production line and ceramic film-forming LED lamps are leading domestically. There are more than ten related patents, including three invention patents. .
Ceramic film forming technology has the characteristics of working under high voltage, high temperature, high frequency and high power. It is widely used in the heat dissipation of LED and other power devices, high pressure resistance requirements and microwave environment.
The person in charge of the Planck exhibition said that the ceramic lamp has the characteristics of high temperature resistance and high pressure resistance, and the ceramic-free aluminum substrate, the factory price of 7W is 15 yuan.
