Abstract

Disclosed is a kit for converting an existing high discharge light unit to an LED based light unit, with the option of including a networked capability among a group of LED light units. The kit includes a drop-in component mounting plate on which are mounted an LED light source, sensors including a thermal sensor, a control unit, a DC power supply, a heat sink, and a dimmer unit. A wireless transceiver allows the LED light units to operate as a network, with two way flow of information from the LED light units to a control unit.

Claims

1. A kit for retrofitting an existing high intensity discharge lamp in a fixture for conversion to an LED light output unit, comprising:

a mounting plate with heat sink characteristics and configure for thermal contact with said fixture, said mounting plate serving as a platform for placement of kit components, with said mounting plate shaped for engagement and attachment with a selected fixture;

a driver for supplying power to one or more LED light sources;

one or more LED light sources;

a heat sink separate from said mounting plate;

a dimmer unit, for adjusting the power to said one or more LED replacement;

a sensor linked to said dimmer unit, to adjust the power to said one or more LED light sources based on a sensed input; and

a thermal sensor connected to said dimmer unit, for detecting heat overloads and reducing power to said one or more LED light sources to keep said replacement LED light sources within thermal limits.

2. The kit for retrofitting an existing high intensity discharge lamp of claim 1, in which said sensor is a motion detector, configured to signal for brighter light when motion is detected and for less light or no light when motion is not detected.
