The increasing popularity of LED light bulbs

In led lighting applications, dimming technology face large challenges, due to the LED lighting use more current drive mode, while dimmer mainly use multi-voltage dimming, so the compatibility challenges is considerable, however, this is also a weapon to distinguish the program merits, in the past LED dimming solution, the common problem is the dimming range is small, it will suddenly lights when dimming, flashing, which is seriously affect the user using experience, but With the PI and other company-specific programs launched, LED dimming problem is expected to solve. the latest PI LYTSwitch IC can be achieved excellent dimming performance, even in low conduction angle it also can easily reach NEMA startup speed of SSL6 standards, besides, the drive is very fast, usually less than 500 milliseconds, even if 10% of the amount of light output is turned on its startup speed is also fast. In the actual program, the use of the bulb LYTSwitch IC design is able to off almost the same as when dimming the angle of conduction, which virtually eliminates led light suddenly become brighter. Furthermore, the dead zone in the SCR light is eliminated; this is because the LYTSwitch controller can ensure immediately dimming when the dimmer start working. In this facet, the PI-called proprietary circuit technology from dimming curve, advantages of PI program are obvious.

Compatibility issues of dimming technology is another challenge, there is not a program can be 100% compatible with dimmer, if could achieve 80% /90% is not bad, it seems that PI dimming has really done a lot of works. With the increasing popularity of LED light bulbs, dimming technology upgrade can bring more and better experience, which will become a new selling point, when choose the scheme, company can look at this function. In support dimming mode, the manufacturers generally supported SCR dimming and PWM dimming.
