Non-dimmable LED Bulb
With phase-out policies in place for traditional incandescent bulbs in many countries, energy saving alternatives in particular LED retrofit bulbs, e.g. A-lamps, globes, PAR, GU10, etc. are enjoying great popularity. Currently LED driver designs and system costs are still a challenge to gain major consumer acceptance.
Infineon offers benchmark solutions and represent an outstanding choice to overcome this hurdle. The ICLSx-series for non-dimming LED retrofit bulbs and other LED lighting applications operated from AC mains deploys fixed frequency operation mode with integrated power factor control. Applied innovative primary control techniques result in excellent system efficiencies with significant reduced external component count. The integrated CoolMOS™ simplifies designs and enables compact applications for integration in standard screw-in sockets and LED luminaires.
