Lighting device utilizing an LED light source for projection of a light pattern onto a surface

Abstract

A lighting device utilizing a light emitting diode (LED) light source for projection of a light pattern onto a surface with an LED lamp socket, an adjustable LED lens attachment, and a mechanism for varying the focal length by adjusting the distance from the LED lamp socket relative to the lens attachment. The device preferably utilizes a replaceable, multiple LED lamp as a light source and a lighting fixture allowing for imaging of the LED light source onto a surface at varying distances from the light source. The device illuminates a surface with an image of the LED element array present in the replaceable lamp. Through adjustment of the LED lamp light source with respect to the imaging lens, the image of the LED array may be focused and distorted for a desired visual effect.
