Irrespective of the specific lighting technology, the ability to effectively control the light source is essential. Beyond a simple on/off switch, advanced lighting control provides the opportunity to provide additional intelligence and increased energy savings.
The ability to dim any light source is the most common requirement of a light controller, but it also is a potential obstacle. Most legacy dimmers are simple triac dimmers that can vary the light output of an incandescent light source from 0–100%. Specialized methods such as varying Pulse-Width Modulation (PWM) frequency or variable current is required to dim LED and fluorescent lighitng. Our solution can provide these capabilities and more.
Functions such as dimming and timers are common, but adding intelligent control to your design enables you to provide improved user interfaces and value. Integrating elements such as energy management/harvesting (e.g. solar), ambient light compensation (reducing light output based on other localized light sources), and occupancy or motion sensing can deliver incremental energy savings.
Our solutions make it easy for you to integrate these capabilities into the luminaire ballast/driver, wall controller or remotes.
