  • LED lighting device
    Patent number: 6758582
    Abstract: 9A light emitting diode (LED) lighting device includes a concave mirror and a convex mirror having a diameter less than a diameter of the concave mirror. The convex mirror is positioned to face the concave mirror and is fixed to the concave mirror. An LED array is fixed to the concave mirror between the concave mirror and the convex mirror. The LED array faces the convex mirror such that light emitted by the LED array reflects off of the convex mirror. A power supply is provided for powering the LED array. Light emitted by the LED array is reflected from the convex mirror onto the concave mirror, and then reflected by the concave mirror to exit the lighting device.
