Abstract:
1. A method for operating a plurality of light emitting diodes (LEDs) residing in a secure LED fixture that is configured to detachably couple to a secure LED fixture mounting, the method comprising: coupling a secure LED fixture to a secure LED fixture mounting, the secure LED fixture comprising the plurality of LEDs, a connector to a power source, and a security sensor; providing power to the plurality of LEDs, the power provided via the connector, and the power provided by a power source external to the secure LED fixture; sensing on the connector the power provided to the plurality of LEDs, wherein the sensing is performed by the security sensor residing in the secure LED fixture, the security sensor comprises a resistor, and wherein sensing the power comprises: sensing a change in a voltage of the resistor; in response to sensing the power on the connector, communicating an authorization signal from the security sensor residing in the secure LED fixture to a LED driver and controller that is external to the secure LED fixture when the sensed voltage change of the resistor corresponds to powering the plurality of LEDs; and maintaining power to the plurality of LEDs only in response to communicating the authorization signal.
