Patent ID: 7178937

Claim:
A lighting device having at least one light-emitting diode as a light source, the lighting device comprising: a housing; a reflector, which has a central axis, mounted at least partially in the housing; said at least one light-emitting diode mounted in the housing on a front side of the reflector, arranged so that at least a substantial majority of light output from the light-emitting diode is reflected off the surface of the reflector and past the light-emitting diode; a supporting element arranged in-front of the reflector for supporting the light-emitting diode; a protective filter or lens attached to the housing, protecting the light-emitting diode and reflector, and preventing soiling of the reflector; and a focusing portion enabled to adjust a relative position between the light-emitting diode and the reflector in a direction substantially parallel to the central axis, the relative position of the light-emitting diode and the reflector determining the beam spread projecting from the lighting device.
