20160377267 | LED LAMP STRUCTURE AND ILLUMINATING MODULE THEREOF - In a LED lamp structure and an illuminating module thereof, the illuminating module includes a circuit board, a flat plate LED, an electrical pin and a packaging colloid. The circuit board has a length, a first and a second side formed at two sides of the length. The flat plate LED is fixed and electrically connected with the circuit board, bulges at the first side, and includes a substrate and at least one LED grain assembled on the substrate. The flat plate LED can emit omnidirectional light because the substrate is made of transparent material. The electrical pin is fixed and electrically connected with the circuit board and bulges at the second side. The packaging colloid covers the circuit board and the flat plate LED and has a rectangular plastic block. Thereby, the LED lamp structure can remain traditional appearance of a halogen lamp, for collecting and focusing light. | 12-29-2016 |

20090231855 | UNIFORM WASH LIGHTING FIXTURE AND LENS - A parabolic aluminized reflector (PAR) lighting fixture is provided with a faceted lens having many distinct lens elements. A plurality of first lens elements use light refraction to direct light from the collimated beam supplied from the fixture reflector to uniformly illuminate segments of a region of an adjacent wall surface. A plurality of second lens elements use internal reflection to direct light from the collimated beam to uniformly illuminate other, off-axis segments of the region. The resulting highly asymmetric beam distribution pattern provides wall wash or cyc capability with a widely available PAR fixture and eliminates the need for dedicated cyc or wall wash fixtures. | 09-17-2009 |
20100039823 | LIGHT SOURCE DEVICE AND PROJECTION DEVICE UTILIZING THE SAME - A light source device for a projection device includes a lamp and a reflector. The lamp includes a light emitter and two electrode arms. The light emitter emits light, and the two electrode arms include reflective coatings, and are integrally formed with the light emitter. The reflector retains the lamp and includes a curved reflective inner surface in a parabolic shape. | 02-18-2010 |
20100315819 | FRONT SHEET AND DISPLAY DEVICE USING THE SAME - A technique for a display device using a display panel with Lambert light distribution, such as a plasma display panel, which displays a bright image with less contrast deterioration. This device has a front sheet which is integrally or separately located in front of the display panel. The front sheet includes light guides which extend in the horizontal direction and have a virtually convex cross section in the vertical direction with their apexes on the light exit side. A light reflection layer and a light-absorbing layer are sequentially stacked on the lateral sides of the light guides. | 12-16-2010 |
20110090700 | LIGHT SOURCE MODULE - A light source module includes a light source and housing. The housing includes a reflecting part, an installed part, and a stop. The reflecting part includes a paraboloidal surface configured for reflecting light beams from the light source. The light source is set in a focal point of the paraboloidal surface. The installed part is configured for installing the light source. The opening is configured for transmitting light beams reflected from the paraboloidal surface. The stop is perpendicularly connected with the installed part, and configured for preventing light beams from the light source from directly passing through the opening. | 04-21-2011 |
20110249445 | PARABOLIC REFLECTOR AND RELATIVE LED LIGHTING DEVICE - Axial symmetric parabolic reflector comprising an opening and which is positionable in a position in which it surround the at least a led lighting source for reflect and distribute in homogeneous way a light flux toward the opening. The axial symmetric parabolic reflector comprises a mask which is made integral with the same, besides the mask being positionable in proximity of the at least a led lighting source in a way to results substantially orthogonal to a longitudinal direction in order to avoid the direct eyesight of the at least a led lighting source through the opening. | 10-13-2011 |
20120014111 | LED LAMP COMPRISING LIGHT GUIDE INCLUDING FIRST AND SECOND DIFFUSING SURFACES - An LED lamp is described, the LED lamp comprising an LED unit, e.g. provided on a base, in an embodiment, a fitting for contacting a power supply, and a light guide arranged to receive a light beam from the LED unit and guide the light beam towards a first light diffusing surface thereby providing a diffused light beam and whereby the light guide further comprises a second light diffusing surface facing the first light diffusing surface for diffusing at least part of the diffused light beam. The LED lamp as described enables to provide an omnidirectional light distribution, comparable to the light distribution of a conventional filament based light bulb. | 01-19-2012 |
20120275167 | Lighting system for Video conferencing - A lighting system for video conferencing includes a reflector structure positioned in an enclosure and having one or more light sources positioned therein to reflect light in a selected direction. A diffuser lens plate overlies the reflector structure to diffuse light emanating from the reflector structure. The reflector structure may include a plurality of parabolic reflectors having the shape of circular paraboloids. The light sources may include LED's positioned at the parabolic foci of the reflectors. The diffuser lens plate is translucent and may be colored yellow to filter light from the LED's. The diffuser has a surface texture which diffuses light from the LED's. | 11-01-2012 |
