Demand for high-power LEDs is increasing, and crystal power will strive for LED integration.

Topic: At the 6th China International Semiconductor Lighting Forum "Materials, Devices and Equipment Branch" held in Shenzhen, Xie Mingxun, deputy manager of Jingdian, gave a report titled "Technology Development of High Power LED Chips".

In recent years, due to the advancement of LED technology, its application has become more and more extensive, and the market demand for high-power LEDs is also increasing. Xie Mingxun pointed out that there are many similarities in the design of high-power LEDs and traditional small-size LEDs, such as how to spread the current evenly and how to further improve the light extraction efficiency, but the biggest difference is the heat problem, in order to make the LED High reliability still maintains high reliability. How to solve heat dissipation is one of the most important issues. Xie Mingxun believes that LED itself still has some problems to be solved, including cost, luminous efficiency and heat dissipation. While these problems have been eliminated, Jingdian is also committed to the development of LED integration solutions, making the future use of LEDs simpler and more user-friendly.

DB-S Diode

DBS diode series patch rectifier bridge stack is composed of 4 rectifier diodes connected and packaged in the form of a bridge full-wave rectifier circuit, which belongs to a full bridge. There are four lead-out pins, the connection point of the negative poles of the two diodes is the "positive pole" of the DC output terminal of the full bridge, and the connection point of the positive poles of the other two diodes is the "negative pole" of the DC output terminal of the full bridge. Reverse repetitive peak voltage range: 50V~1000V, average rectified output current 0.8A~1.5A: forward non-repetitive surge current 30A (60Hz sine wave, one cycle, Tj=25°C). For specific parameters, please refer to the specification or consult online customer service.
