BLE Connected Dimmable Tunable White LED Light Circadian Lighting Design Guide (Rev. A) (PDF 6657 KB)

Description

The TIDA-01096 TI design is a tested DC-DC LED driver sub system for tunable white LED luminaires. It is built-on a wireless SoC platform which can enable intensity adjustment (dimming) and co-related color temperature (CCT) control using any BLE smart device. Tunable white light luminaires simulate daylight conditions. With a separate warm-white and cold-white LED string, it allows CCT tuning and thereby helps achieving proper circadian stimulation. TI design TIDA-01096 provides high efficiency DC-DC conversion and allows dimming and color temperature control over more than 1:50 and 1:500 range using analog and PWM methods.
