LED Ballasts
The unique, low-power, non-flickering, directional output capabilities of LEDs make them perfect for indoor lighting under counters and in hallways, staircases; concentrated arrays can also be used for room lighting. Rugged and damage-resistant, LEDs are also a cost-effective solution for outdoor applications such as garden walkways and decorative features.
Features and Benefits
- The Atmel® AVR® AT90PWM microcontroller supports the DALI standard to network multiple ballasts to a centralized system for tighter light level control and big energy savings.
- Cost-effective designs require flexibility. Atmel solutions let you build fluorescent lighting solutions based on, for example, a full-featured single-chip AVR especially designed for wireless applications, or a general microcontroller with range of standard-compliant transceiver options.
- To accelerate time-to-market, Atmel provides development packages with evaluation and debug tools, and ballast demo kits with complete, updatable C code to implement advanced control and protection algorithms in the microprocessor memory.
LED Ballasts
- LED ballasts must provide LEDs with a constant source of current. Built-in hardware modulator, a high current LED driver and interrupt options makes the AT90PWM microcontroller well suited for LED applications.
