| 20110063858 | Hexadecimal RGB and CMYK Light Reflecting Surfaces and Techniques - A light reflector having decimal and hexadecimal color models directly applied on light reflecting surfaces used in light reflecting equipment such as parabolic light reflectors and bounce boards. The color models on the reflecting surfaces produce desirable light in colors used in photographic and cinematography productions such as for stage, studio, video, motion picture and still photography. | 03-17-2011 |
| 20130063954 | LAMP SHIELD - A lamp shield ( | 03-14-2013 |
| 20130170227 | Lampshade - A lampshade comprises a support seat, a reflector, and a cover. The support seat includes a frame and a clamping unit, the frame defining a central space, the clamping unit having two opposing connection bars attached to the frame and two grasp portions each being provided at one end of a corresponding connection bar. The distance between the two grasp portions is adjustable. The reflector is placed on top of the frame and has a reflective surface that can be fitted through the central space of the frame. The cover is placed on top of the reflector and fastened to the frame from a side opposite to the clamping unit. Accordingly, when a lighting device, such as a flashlight, is clamped by the lampshade, the light emitting from the lighting device can be reflected by the reflector to diffuse into the surrounding environment so as to increase the illuminating range. | 07-04-2013 |
| 20140104855 | APPARATUS AND METHOD FOR FORMING HIGH-RESOLUTION IMAGES FOR LIGHT PATTERN PROJECTION USING ULTRAVIOLET (UV) CURABLE INKS - An apparatus includes a gobo configured to be inserted into a projection gate of a projector. The gobo includes a substantially transparent substrate and a coating on the substrate. The coating includes one or more layers of ultraviolet curable ink material. The gobo may also include an adhesion promoter directly on the substrate, where the coating is directly on the adhesion promoter. The coating may include a stack having multiple layers of ultraviolet curable ink material, where the stack includes ink material of at least two different colors. One layer could have white/reflective ultraviolet curable ink material, where that layer is configured to face a light source of the projector. At least one layer of ultraviolet curable ink material could have a varying thickness, which can control a percentage or a color saturation of light transmitted through the at least one layer of ultraviolet curable ink material. | 04-17-2014 |
| 20140146547 | LIGHT WAVELENGTH CONVERSION UNIT - In a light wavelength conversion unit, a light wavelength conversion member is placed on the emission surface of a semiconductor light-emitting element. The light wavelength conversion member converts the wavelength of blue light, which has emitted from the semiconductor light-emitting element and entered from an incident surface, so as to emit yellow light and then emits the yellow light from an emission surface. A light reflection layer is provided on a lateral face in the surface of the light wavelength conversion member. Here, the lateral face excludes the incident surface and the emission surface. The light wavelength conversion member is roughened such that an average roughness Ra of the lateral face is 0.5 μm or above. | 05-29-2014 |
| 20150009687 | STRUCTURE FOR GUIDING LIGHT INTO GUIDE LIGHT PLATE TO CONDUCT TOTAL INTERNAL REFLECTION - A structure for guiding light into a light guide plate to conduct total internal reflection comprises a guide light plate and a prism; the prism is integrated with the guide light plate or joined to the guide light plate with an optical adhesive layer; the horizontal surface of the prism is parallel to the upper and lower surfaces of the guide light plate; the maximum angle between the horizontal surface and the slant surface of the prism is only 20 degrees to reduce the thickness of the prism greatly to meet requirements of lightness, thinness, shortness, and smallness for the electronic product; due to a special configuration of the prism and a special arrangement between the guide light plate and the prism, the most part of the light shot to the prism by the light source with any projecting angle is guided into the guide light plate to propagate the total internal reflection such that the light has an intensity capable of being sensed. | 01-08-2015 |
| 20150070907 | OPTICAL CONVERTER FOR HIGH LUMINANCES - An optical converter for producing colored or white light from blue excitation light is provided. The converter has good scattering properties to be able to produce nearly white light from the scattered blue light components and the scattered, converted yellow light components. The optical converter includes material including one or more of a YAG ceramic, a LuAG ceramic, and a magnesium-aluminum ceramic exhibiting strong scattering. | 03-12-2015 |
| 20150138782 | HYBRID METALLIZATION ON PLASTIC FOR A LIGHT EMITTING DIODE (LED) LIGHTING SYSTEM - Provided is a multi-layer reflective coating for application to a lighting housing assembly, including a polymer substrate adjacent a polymer base coat layer applied to the lighting housing. Atop the polymer base coat layer is an aluminum adhesion layer, followed by a diffusive barrier layer, and a silver reflective layer. The aluminum adhesion layer promotes adhesion between the polymer base coat layer and the silver reflective layer. The diffusive barrier layer prevents aluminum and silver interaction, which could form a silver and aluminum alloy. A spectrum tunable layer is applied atop the silver reflective layer for spectrum tuning the silver reflective layer for maximum compatibility with a light emitting diode (LED) lighting source. | 05-21-2015 |
| 20150301264 | OPTICAL SHEET MODULE CONSISTING OF OPTICAL SHEETS HAVING DIFFERENT THICKNESSES - An optical sheet module consisting of optical sheets having different thicknesses, includes: a first base film having a predetermined thickness and transmitting light from a lower portion thereof through an upper portion thereof; an upper optical sheet formed on the first base film and having a first structural pattern in which the upper optical sheet protrudes upwardly and the cross-sectional area thereof decreases when progressing toward an upper portion thereof; a second based film laminated beneath the upper optical sheet so as to transmit light from a lower portion thereof to the upper optical sheet; and a lower optical sheet formed on the second base film and having a second structural pattern in which the lower optical sheet protrudes toward the upper optical sheet and the cross-sectional area thereof decreases when progressing toward an upper portion thereof. The first base film is relatively thicker than the second base film. | 10-22-2015 |
| 20160040857 | FLOURESCENCE-EMITTING LIGHT SOURCE UNIT - A fluorescence-emitting light source unit includes: a wavelength conversion member including a front surface as a light receiving surface to receive excitation light, a phosphor, and a rear surface; and a light reflection surface provided on an outer side of the rear surface. The front surface is provided with a front side cyclic structure. The phosphor is configured to convert the excitation light received in the light receiving surface to fluorescence and to emit the fluorescence. The rear surface is provided with a rear side cyclic structure. | 02-11-2016 |
