Abstract

Disclosed herein is an LED-based light for replacing a fluorescent bulb in a conventional fluorescent light fixture. The LED-based light includes a housing having a first end opposing a second end, a circuit board disposed within the housing and extending along a longitudinal axis of the housing, at least one LED mounted to the circuit board, at least one end cap disposed on one of the first and second ends of the housing, the end cap including a switch and at least one electrically conductive pin configured for physical and electrical connection to the light fixture; and circuitry configured to provide a current path between the at least one LED and the at least one electrically conductive pin, wherein the switch is configured to selectively disconnect the current path.

Dependent claims

An LED-based light for replacing a fluorescent bulb in a conventional fluorescent light fixture comprising:

at least one LED;
an elongate housing for the at least one LED;
an end cap disposed at a first end of the housing, the end cap including at least one electrically conductive pin configured for physical and electrical connection to the light fixture;
a pin cover extending from the end cap, the pin cover substantially enclosing the at least one pin in a protracted position, and supported for retraction into the end cap from the protracted position to at least partially expose the at least one pin;
circuitry configured to provide a current path between the at least one LED and the at least one electrically conductive pin;
and
a system for retracting the pin cover from the protracted position and selectively disconnecting the current path, the system including a movable projection coupled to the pin cover, wherein manual movement of the projection actuates retraction of the pin cover from the protracted position and engages a switch to create an open circuit condition in the current path.
