Abstract
Official abstract text for this publication.
A system and method for operating one or more light emitting devices is disclosed. In one example, the light emitting devices may be deactivated in response to a rate of temperature rise of the light emitting devices. The system and method further include a way of reducing false positive indications of light emitting device.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for operating a plurality of light emitting devices, comprising: supplying an electrical current to the plurality of light emitting devices; and stopping flow of the electrical current in response to a rate of temperature increase of the plurality of light emitting devices exceeding a threshold rate of temperature increase. 2. The method of claim 1 , where the flow of the electrical current is stopped via an electrical…
