Patent number: 6540360Abstract: A projector is provided which can project a high quality image unaffected by dust, or the like, scattered in the projector by preventing the temperature of light-modulating elements from rising. Light transmissive plates are adhered to the light emitting surface of a liquid crystal panel for red light and the light emitting surface of a liquid crystal panel for green light. The amount of heat transmitted from the polarizing plates, which generate the heat, to the liquid crystal panels is reduced by the light transmissive plates. In addition, dust, scattered in the projector, does not stick onto the light emitting surfaces of the liquid crystal panels. In contrast, a light transmissive plate is not provided at the light emitting surface of liquid crystal panel for blue light having a high energy value per unit quantity of light. Thus, the problem of a light transmissive plate preventing heat dissipation at the liquid crystal panel is eliminated, so that efficient cooling can be achieved.Type: GrantFiled: September 23, 1999Date of Patent: April 1, 2003Assignee: Seiko Epson CorporationInventors: Mutsuya Furuhata, Akitaka Yajima, Shinji Haba

Patent number: 6540364Abstract: The invention provides a projector capable of reducing costs and promoting miniaturization while also being dust-proof. A second sirocco fan with an air-inlet opposing a projection lens is used, and an air-inlet of an outer case is formed on a side face thereof. Thereby, it is difficult for dust to be sucked therein compared with an air-inlet formed on the bottom or top face of the outer case, enabling the projector to be dust-proof without any filter. Since the filter is not required, the number of parts is reduced, thereby reducing costs. Furthermore, the second sirocco fan is placed by utilizing a space under the projection lens, which is liable to be a dead space, enabling the arrangement space to be efficiently used thereby promoting miniaturization of a projector.Type: GrantFiled: June 12, 2001Date of Patent: April 1, 2003Assignee: Seiko Epson CorporationInventors: Takeshi Takizawa, Shinsuke Ito

Patent number: 6540382Abstract: A lighting assembly which includes light source means and collimating means for substantially collimating the light from the source. There are transmission means for transmitting the substantially collimated light to a point remote from the collimating means, and, in one arrangement, having an upper section which allows transmission of light therethrough and a lower section which reflects light. Light direction modifying means such as a lens or a reflector is located in the transmission means and remote from the collimating means for receiving light from the collimating means and modifying the direction of the light to pass outside of the transmission means through the light-transmitting section. The light direction modifying means includes a large plurality of prisms on the outer surface thereof. The prisms may be arranged so that the radii of several adjacent ones substantially meet at a point, thereby to form a “wave” lens.Type: GrantFiled: November 30, 1999Date of Patent: April 1, 2003Inventor: Jerome H. Simon

Patent number: 6540383Abstract: A disassembly-type lamp shade structure of simple assembly and reduced physical dimensions includes a top ring, a bottom ring of larger circumference than the top ring, and frame members propped between the top ring and the bottom ring. The top ring has support rods extending outwardly from the center having at their extremities upward bends forming insertion hooks. The bottom ring has sleeve mounts for the insertion of the frame members, after which the upper horizontal curved rods of the frame members are situated against the insertion hooks at the extremities of the support rods and lower horizontal curved rods are situated against the bottom ring, thereby positioning and limiting the movement of the frame members. At the area of confluence between the frame member upper horizontal curved rods and the support rods, the upper horizontal curved rods have downward indentations serving as a catch hook that secures the insertion hook.Type: GrantFiled: January 3, 2001Date of Patent: April 1, 2003Inventor: Wen-Chang Wu

Patent number: 6540386Abstract: A vehicular headlamp wherein aiming adjustment of two reflectors can be conducted accurately regardless of the positional relation between aiming screws operating in conjunction with each other. The headlamp includes first and second reflectors mounted in a lamp chamber defined by a lamp body opening at its front and a lens covering the front opening of the lamp body, the reflectors each being tiltable by turning of an aiming screw of a corresponding aiming mechanism that supports the corresponding reflector in a tiltable manner relative to the lamp body. A belt mechanism rotationally couples the two aiming screws for allowing the first aiming screw for tilting the first reflector and the second aiming screw for tilting the second reflector to be turned in conjunction with each other.Type: GrantFiled: October 24, 2001Date of Patent: April 1, 2003Assignee: Koito Manufacturing Co., Ltd.Inventors: Yuji Fujino, Takasumi Aoki
