Abstract
An automated dimming load controller automatically measures the relationship between the current draw and the dimmer setting for each light or group of lights connected to the load controller. Once measured, the relationship between the current draw and the dimmer setting can be used to enable the dimmer controller to adjust the lights between their minimum and maximum effective illumination. This automatic setting of the dimmer controller may be performed regularly to accommodate changes in performance or replacement of any of the connected lights, drivers or ballasts.
Claims4
A lighting system, comprising:
- a lighting controller comprising:
- a dimmer controller having a dimmer setting;
- a current measurement module for measuring current applied to dimmable lights;
- a microprocessor operably connected between the dimmer controller and the current measurement module;
- a memory operably connected to the microprocessor;
- and
- an algorithm stored in the memory to enable the microprocessor to calibrate the dimmer controller;
- one or more dimmable lights operably connected to the dimmer controller;
- and
- a lighting driver interposed between each of the one or more dimmable lights and the dimmer controller.
