White light dimming is perhaps the most keenly sought after solution in the SSL general illumination market today. Light-Based Technologies (LBT) has developed and markets a white light dimming solution with a host of unique and valuable features.
Light-Based’s LB4 linear current control IC delivers dimming efficiencies far superior to those achieved with typical digital control topologies. The LB4 cost-effectively provides unsurpassed flexibility in control inputs, while still maintaining a high level of dimming performance.
The LB4 accepts input from a variety of single channel input controls:
Trailing Edge Dimmers
Leading Edge Dimmers
0 – 10 volt Dimmers
The LB4 also offers the ability to accept feedback from the LED light engine. Feedback characteristics include temperature for heat management, color temperature for quality of light, and voltage and current for efficiency management.
The programmable nature of the output curve enables flexibility in terms of performance, as well as future proofing electronics designs to accommodate the regular upgrades and changes in LEDs and other components.
