LED Bulb (Triac Dimmable)

Overview

Coloured LEDs are commonly used as indicator lamps in many devices, however white LEDs are now being increasingly used for general lighting. LEDs present many advantages over incandescent light sources including lower energy consumption, longer lifetime, higher brightness, improved robustness, smaller size, faster switching and greater reliability.

LEDs need to be able to replace traditional lighting (incandescent and fluorescent-tube) in the locations they are used as is (retrofit). In some cases, traditional lighting with a dimming function achieved by a triac dimmer is used, so the LEDs that replace these also need to be triac-dimmable. Renesas' R2A20134SP LED driver IC and RJKxxxx Series driver MOSFETs can be used to configure a triac dimmer circuit. These product series meet the demands for low cost, low power, and small size for LEDs.
