Abstract

A low-voltage alternating current-based LED light with built-in cooling and automatic or manual dimming. As it is self-cooled with fan failure protection, the light can be safely run in conditions that are near-hostile to its operation, with little possibility of damage. The light is movable along the XY axes of a grid system and can be either fixed in position in the Z axis or can be movable up and down the Z axis. The light can be equipped with either manual dimming using a standard potentiometer, or with automatic dimming via sensors and local network connectivity. The device prevents line-voltage electric shocks as the input voltage is low-voltage AC; in embodiments, about the same voltage as a doorbell, and the input current is 3 A. The device is also self-cooled, and will shut down if its fan is not running so as to prevent thermal overloads.
