20130056706 | QUANTUM DOT LED LIGHT SYSTEM AND METHOD - The present disclosure provides methods of using quantum dots or Q dots or a similar nanocrystal to transfer, for example, excess LED light energy in the blue band to the red band where such LEDs tend to be deficient. This approach would balance the overall spectrum of the LED without a corresponding loss in brightness as would be the case where the light from the LED was passed through a conventional filter. The Q dots could be applied to the lens portion of the LED after the high temperature processes are completed or coated to a clear filter to be placed in the LED light path. | 03-07-2013 |
20130094193 | LED BASED SEARCHLIGHT/SKY LIGHT - LED based searchlight/sky light including, in a basic embodiment, a housing; an LED array supported in/by the housing, a heat sink in communication with the LED array, and a reflector supported in the housing such that the LED array is supported by the housing a distance sufficient above the reflector to allow the light emitted by the LED array to be reflected by the reflector. The reflector is preferably a parabolic reflector such that the light emitted by the LED array is reflected by the parabolic reflector in an intense collimated beam. The LED array may be supported above the parabolic reflector a distance equal to the focal length of the parabolic reflector. A power supply may also be included to regulate the electrical current applied to the LED array. | 04-18-2013 |
20130100678 | PLUG COMPATIBLE LED REPLACEMENT FOR INCANDESCENT LIGHT - According to an aspect of the instant invention, an LED Engine is provided preferably for use with a Fresnel fixture having a globe socket wherein the LED Engine is plug compatible with the globe socket.
