| LED lamp driver scheme based on GreenChip technology to achieve first class dimming compatibility in the industry |
| Time： 2018-06-20 |
NXP Semiconductors N.V. (NASDAQ N.V.) (NASDAQ Code: NXPI) today released SSL2129A - an efficient GreenChip? Controller IC for 4 to 25 W compact deep tunable LED lights. SSL2129A provides per watt of first-class compatible dimming performance measurement based on the single stage LED driver for mainstream applications. This method also allows convenient application to maintain a compact (GU10/PAR16) and high cost, high power factor (PF) greater than 0.9. The device is designed to be used with the external MOSFET, which can be configured as a step-down (non segregated) or a flyback (isolation) topology for 100 to 120V and 230V power supply voltages. NXP in Hongkong International Lighting Fair (booth 5B-C12) unveiled the latest SSL driver chip Green Chip series.

"Our latest GreenChip LED controller IC has set new benchmarks for the compatibility of the dimmer," said Mr. Richard Langezaal, a global product marketing manager at nyesp semiconductor lighting solutions department. In testing and measuring "per watt compatibility", we consider the importance of adjustable LED performance and many other factors at low input power levels. SSL2129A provides excellent dimming performance, high efficiency, and manufacturing convenience in a very compact size, so it will help to substantially reduce the cost of a modified light modified LED lamp.
To evaluate each tile compatible degree
The whole world has sold more than 600 dimmers, and almost all of the products are for the original incandescent lamp design. The lighting products manufacturers, using a variety of dimmer design is reliable and stable light adjustable LED lamp is still a very big challenge. At the same time, as the LED efficiency (every watt lumen number) steadily increases and the input power needed to improve the LED lamp is decreasing, this brings an additional problem: at present, the LED lamps for commercial use need to replace the 40 W incandescent lamp with 7 W, and 8.7 W instead of the 60 W incandescent lamp. But is below 10 W and maintain the dimmer compatibility degree will become extremely difficult.
In order to solve this problem, ngpu developed a "per watt compatibility" scoring method to absorb the power of the market that is absorbed and the controllability (the ability to avoid the visual interference such as flicker, light flicker and flash). (the user can control and reduce the range of light output, including the range of lighting level. The control room and other steps) compatibility composition measures into consideration. Based on the SSL2129A parameters showed a dimming of the excellent compatibility. The assessment will be published later provide NXP dimmer compatibility per watt white paper.
