In this year's Hong Kong International Lighting Fair, NXP showcased its latest UBA2211 drive based on the 13W CFL driven embedded solution, its efficiency can be 90-92% with the current mainstream of the market compared to discrete solutions ratio, based on the driver IC for CFL programs can reduce the number of peripheral components to a dozen, only a very small PCB board can be done and very simple, cost will only increase a few dollars, but also bring a lot of performance .

For example, Chen Rong said, NXP drive power based on UBA2211 the CFL program can solve the following problems: CFL lamp life may be extended 50-150%, switching frequency can be increased 3 times to 30 times, can significantly improve product consistency, photoelectric conversion efficiency can be increased 2-5%, reducing the lamp size, depth of dimming support efficient and shorten the lamp start-up time, reduce product development and labor costs, and constant output power (lower input voltage dependent).

LED driver power supply program and the difference is, CFL drive power scheme does not require the use of specific components to eliminate EMI, which can be used two small ceramic capacitors to achieve this functionality. In addition, the required power input circuit of electrolytic capacitors (mainly used to eliminate the ripple current) drive power will not affect the life of CFL, CFL is because the radiation source, aluminum electrolytic capacitors work environment temperature did not like the LED drive power up to a hundred degrees, so it's working life will not be much impact, most people can reach 6,000 hours of working life.

Chen Rong said: 'currently on the market only about 2% of high-quality-based CFL lamps in the driver IC solutions, we wish to have more use of CFL lamps embedded IC manufacturers drive the program. '

However, for many CFL lamps or drive power developers, the use of IC-driven program also has some practical difficulties. For example, Shenzhen Optoelectronic Technology Co., Ltd Hang Yiu Minister He Qihui said: 'We are now producing both discrete CFL drive power, but also with an IC-style. IC-based program does have many performance advantages, the future development of the mainstream, but for us the realization of some process issues, such as the current drive power of all CFL are the use of wave soldering PCB board (due to cost considerations ), these plants are no placement machine, and therefore require workers to manually mount the IC to the PCB board, which will bring the final result of ESD issues such as drive power reliability problems.

CFL on the market most of the drive can not support a wide dimming depth and therefore can not support all of the TRIAC dimmer. Chen Rong said: 'We all have been developed to support the market the CFL TRIAC dimmer driver chips, it's the depth of up to 1% dimming, but this chip officially released until next year. '
