The supporting seat is for supporting the light source. The first lens array has a plurality of first lens units, and each of the first lens units has a first focal distance. The second lens array has a plurality of second lens units. The distance between the second lens array and the first lens array is 0.5 to 1.5 times the first focal distance. A suitable distance exists between the projection plane and the luminescent set, so that the light beams passing through each of the second lens units cover the entire projection plane. Therefore, the projection plane has excellent illumination uniformity. | 02-25-2010 |
| 20120212963 | APPARATUS AND METHOD FOR OPERATING A PORTABLE XENON ARC SEARCHLIGHT - An apparatus for producing a high intensity beam of light with high efficiency of conversion of electrical power into light intensity includes an arc lamp, a reflector, a screw drive mechanism coupled between the arc lamp and reflector for positioning the arc lamp relative to the reflector to provide zoom control of the beam of light, and a spring for biasing the screw drive mechanism into a stable configuration to eliminate backlash and instability of the positioning the arc lamp relative to the reflector to provide zoom control of the beam of light. A handheld light includes an IR filter selectively disposable over the aperture of the light so that only infrared light and a circumferential light curtain is interposed between the IR filter and the body so that no there are no light leaks even the IR filter and the body are prevented from fitting closely due to interposed debris. | 08-23-2012 |
| 20130170215 | RETROFIT REFLECTOR FOR A FIXTURE - A retrofit reflector for a fixture that may be utilizing an induction lamp, mounts the lamp at a point of zero bending moment on the reflector. The reflector bends widthwise in the fixture to fit within various widths of fixtures while maintaining the lamp along the zero bending moment on the reflector. | 07-04-2013 |
| 20130223076 | SEARCHLIGHT - A projector comprises an arc lamp ( | 08-29-2013 |
| 20140104841 | DISPLAY LIGHT SOURCE - A display light source includes a light source, a color wheel, an optical module, and an actuator. The light source provides a light beam. The color wheel includes a first path segment and a second path segment. Each of the first path segment and the second path segment includes a reflective segment and at least one filtering segment. When the light beam impinges on the filtering segment of the first path segment, the light beam passes through the filtering segment of the first path segment and is filtered to form a first primary-color light beam. When the light beam impinges on the reflective segment of the first path segment, the light beam is reflected to the optical module. The optical module guides the reflected light beam to the filtering segment of the second path segment, such that the reflected light beam is filtered to form a second primary-color light beam. | 04-17-2014 |
