20150231429 | UNIDIRECTIONAL, SPRINKLER-TYPE, ANTIPERSONNEL-FRAGMENTATION-FREE FIRE-EXTINGUISHING BOMB - The invention discloses a unidirectional spray type fire extinguishing bomb without high explosive fragmentation, includes a housing, a fuse, an igniter, an fire extinguishing agent and a main charge, and further includes a tail braking device, combustor, a plate closure, a piston and a diffuser. The housing, the tail braking device and the piston are made of light metal materials; the housing is cylindrical; the tail braking device is arranged at the bottom of the housing and is fixed with the housing through a screw nail; and the fuse is arranged on the diffuser and is fixed through a screw nail. During working process, when the fuse detects the fire extinguishing bomb to be 5-10 meters far away from a combustion source, the igniter ignites the main charge, the piston is pushed under high pressure to move in the housing, and the fire extinguishing agent is sprayed out from spraying holes to the combustion source for fire extinguishing. The present invention has simple structure, and has no lethality when the fire extinguishing agent is sprayed. | 08-20-2015 |

Wherein the lampshade includes a set of light-reflecting structures, each light-reflecting structure in the set of light-reflecting structures is used for respectively reflecting rays in a middle portion of light emitted from a light source corresponding to the light-reflecting structure towards two sides of the corresponding light source. Correspondingly, a backlight unit including the light-emitting device and a display device including the backlight unit are provided. The light-emitting device according to the present invention can improve a Hotspot phenomenon effectively. | 06-12-2014 |
20140160796 | Light Guide Plate and Fabrication Method Thereof, Extrusion Equipment, Backlight Module and Display Device - The present invention discloses a light guide plate (LGP) capable of bidirectional focusing via a bidirectional micro-transmissive layer, a fabrication method of the LGP, an extrusion equipment, a backlight module and a display device. The LGP comprises a LGP substrate, the LGP substrate comprises at least one incident surface for receiving a light beam and one outgoing surface connected to the at least one incident surface, a bidirectional micro-transmissive layer is provided in the LGP substrate, the bidirectional micro-transmissive layer comprises a plurality of micro-transmissive points having biconvex surfaces. According to the principle that convex lens converges light, the design of micro-transmissive points having biconvex surfaces causes several scattered light beams having different directions that enter the micro-transmissive points to be converged, which effectively improves the brightness of the outgoing surface of the LGP, thereby improving the brightness and definition of images displayed in the liquid crystal panel. | 06-12-2014 |
20150260897 | LIGHT GUIDE PLATE, BACKLIGHT SOURCE ASSEMBLY AND DISPLAY APPARATUS - The present invention discloses a light guide plate, a backlight source assembly and a display apparatus. The light guide plate comprises: a light incident surface formed with a plurality of first microstructures thereon, the plurality of first microstructures being configured to deflect a part of light entering through the light incident surface toward the light incident surface of the light guide plate; and at least one cavity inside the light guide plate, a side wall of each cavity distant from the light incident surface being formed with a plurality of second microstructures thereon, the plurality of second microstructures being configured to further deflect a part of the light striking on the second microstructures through the cavity toward the light incident surface of the light guide plate. The light guide plate of the present invention of the present invention is able to reduce an area of a dark strip zone occurring at a light incident portion of the light guide plate, thus alleviating the phenomenon of alternate bright and dark strip zones occurring at the light incident portion of the light guide plate, thereby improving display performance of the display apparatus. | 09-17-2015 |
20150323836 | LIGHT COMPENSATOR, SHADING TAPE, BACKLIGHT MODULE AND DISPLAY DEVICE - The present invention provides a light compensator, a shading tape, a backlight module and a display device. The light compensator comprises a first surface on which at least one recess is provided, wherein, when the light compensator is arranged above an edge of an optical element, the first surface faces a light-exiting surface of the optical element, and a surface of the recess is capable of converging light irradiating thereon and reflecting the light toward an area with low luminance on the light-exiting surface of the optical element. The above light compensator can perform light compensation on areas with low luminance on the light-exiting surface of the optical element, enhance the luminance of the areas with low luminance on the light-exiting surface of the optical element, and achieve luminance uniformity of respective areas on the light-exiting surface of the optical element. | 11-12-2015 |
