| 20100110722 | LIGHTING DEVICE AND DISPLAY DEVICE INCLUDING THE SAME - A lightening device and a display apparatus are disclosed. A lightening device includes at least one light source installed on a substrate, spaced apart a predetermined distance with each other, and a filter member provided over the light source with a variable thickness, the filter member where light emitted from the light source transmits. A display apparatus includes a panel displaying an image, a front cover supporting a front edge portion of the panel, and a lightening device mounted in an opening portion formed at the front cover, the lightening device being exposed outside. The lightening device includes at least one light source installed on a substrate, spaced apart a predetermined distance with each other, and a filter member provided over the light source with a variable thickness, the filter member where light emitted from the light source transmits. | 05-06-2010 |
| 20120099340 | BROADBAND HIGH POWER LIGHT SOURCE - The present invention relates to a super continuum light source comprising a pump source arranged to emit light having a center wavelength λ | 04-26-2012 |
| 20100080018 | COMPENSATING LIGHT GUIDE - The invention relates to a compensating light guide ( | 04-01-2010 |
| 20110170313 | LIGHT SOURCE ASSEMBLIES - A light source assembly comprises a light pipe, a first color light source at a first tapered light collector, a second light source at a second tapered light collector, and at least a first dichroic filter operative to pass first color light and to reflect second color light toward a light output port. A light valve may be positioned to receive light from the light pipe. One or more light entrances to the light pipe may have a filter, e.g., a short wave pass filter, oriented in a plane generally parallel to the axial optical pathway. | 07-14-2011 |
| 20110205753 | OPTICAL WAVEGUIDE SYSTEM USING ELECTRODELESS PLASMA SOURCE LAMPS - An optical waveguide system with an electrodeless plasma lamp as the electromagnetic radiation source. The system includes an optic source coupling element that receives the electromagnetic radiation that is emitted from at least one electrodeless plasma lamp. The optic source coupling element is coupled to at least one optical waveguide element. The optical waveguide element includes at least one fiber optic cable that is capable of transmitting the emitted electromagnetic radiation. The fiber optic cable can be positioned such that the electromagnetic radiation is transmitted at a desired position away from the electrodeless plasma lamp source. | 08-25-2011 |
| 20110141763 | LIGHTING APPARATUS - In a lighting apparatus which emits light of a desired wavelength by irradiating excitation light from a light source to a wavelength converting member, a structure is such that a part of wavelength-converted light which is launched from the wavelength converting member is made to launch from an irradiated-light emerging area without making the light incidence again to the wavelength converting member. | 06-16-2011 |
| 20110228555 | LIGHTING DEVICE - A lighting device ( | 09-22-2011 |
| 20110002139 | LIGHT PIPE - Disclosed is a light pipe including a body having a hollow therein, and plural prism sections on an outer surface of the body. Each prism section includes a reflection section, a cross section of which is an isosceles right triangle, and an angle adjusting section. The angle adjusting section has a cross section in the shape of a right-angled triangle, a base side of which is an oblique side of the isosceles right triangle. A vertical angle of the right-angled triangle varies with the position of a light source. Installation of the light source at the center of the cross section of the light pipe is not required, thereby increasing the manufacturing efficiency of the light pipe. The light pipe has an internal surface in various shapes including a cylindrical shape to be applicable to various application fields. Power is saved, and light is transmitted to a remote place. | 01-06-2011 |
