| Title: |
Lighting Device With Beam Altering Mechanism Incorporating a Plurality of Light Sources |
| Abstract: |
An apparatus is disclosed incorporating a plurality of light sources, such
as a plurality of lighting emitting diodes, and a beam altering mechanism
for altering the light projected by the plurality of light sources.
Several mechanisms for altering the beam produced by the plurality of
light emitting diodes are disclosed. The present invention can be used in
for example hand held flashlights and theatrical lighting. The present
invention in one embodiment discloses a hand held flashlight
incorporating a plurality of light sources and a beam altering mechanism
capable of changing the color of the emitted light beam produced by the
flashlight. The beam altering mechanism may be comprised of an aperture
device, which may be an aperture plate, provided with a plurality of
apertures that are strategically aligned with the individual light beams
emitted from each of the plurality of light sources. In one embodiment
additional apertures containing color modifying filters may also be
strategically placed in the aperture device and these modifying filters
can be aligned over each of the light sources by rotation of the aperture
device. The aperture device may be round and may be mounted centrally to
a substrate on which the plurality of light sources are mounted. The
plurality of light sources can be arranged symmetrically to provide
uniform illumination. The aperture device can be arranged with a
plurality of apertures that contain light refractive optics that are
strategically placed in the aperture device and provide a means for
changing the focus of the overall beam produced by for example a
flashlight. The plurality of light sources and the aperture device may be
incorporated into a remote controlled lighting device.
