The movable element is operable to move the colored pieces along a moving direction to align a selected one of the colored pieces with the lighting module. | 10-04-2012 |
| 20130208481 | ADJUSTABLE FOCUS LIGHT - A light fixture comprises a lens frame, a lens on the lens frame and a light source. The lens and light source are movable relative to each other between a first position in which the lens and the light source are nearer each other and a second position in which the lens and light source are further away from each other, wherein light produced by the light fixture is more focused or more diffuse according to the relative positions of the lens and the light source. | 08-15-2013 |
| 20150062906 | PORTABLE FRAMING PROJECTOR - An apparatus includes a framing projector with a light source and one or more focusing elements that focus light from the light source on a desired area of an object. The one or more focusing elements are to prevent light from the light source from lighting areas outside the desired area. The apparatus includes a projector housing. The framing projector is mounted inside the projector housing. The apparatus includes an electrical cord terminating at a plug configured to plug into an electrical outlet. The electrical cord provides power to the framing projector. The apparatus includes a stand coupled to the projector housing and/or the framing projector. The stand maintains the projector housing and framing projector in an upright position above a substantially horizontal surface when the stand is positioned on the substantially horizontal surface. The stand supports the projector housing and framing projector against gravity loading of the apparatus. | 03-05-2015 |
| 20160018081 | ILLUMINATION DEVICE - An illumination device has plural LED light sources, a reflection plate that has plural openings facing the respective LED light sources, and plural lenses that faces the respective openings and that guides light emitted from the plural openings in a direction vertical to the openings. The reflection plate is placed between the plural LED light sources and the plural lenses, and converges the light emitted from the plural LED light sources. | 01-21-2016 |

| 20100135023 | LIGHTING DEVICE - A lighting device having a light source and devices for changing the illumination area, comprising two arrangements made of transparent flat components with oblong imaging elements disposed next to each other in a parallel fashion, having a surface deviating from a plane on at least one side, the imaging properties of the component arrangements can be changeable and the longitudinal axes of the one component arrangement being perpendicular to those of the other, characterized in that the light source is a matrix-shaped arrangement of light emitting diodes. | 06-03-2010 |
| 20100246183 | AUTOMATED LUMINAIRE IRIS - Described are an improved automated luminaire | 09-30-2010 |
| 20110038161 | Lighting Device - A lighting device includes a light source, first and second beam-directing prism elements, and a transmission device. The light source emits a light beam. The first beam-directing prism element is arranged in a first direction. The second beam-directing prism element is arranged in a second direction and partially overlapped with the first beam-directing prism element. When the light beam passes through different regions of the first and second beam-directing prism elements, different bending angles are resulted. The transmission device is connected to the first and second beam-directing prism elements for driving movement of the first beam-directing prism element in the first direction and movement of the second beam-directing prism element in the second direction. Accordingly, the light beam emitted by the light source simultaneously passes through one of the regions of the first beam-directing prism element and one of the regions of the second beam-directing prism element. | 02-17-2011 |
