Abstract: This invention relates to the improved support rod and the fixing sheath for the lampshade. The basic structure of the lampshade is composed of several upper and lower fixing sheaths, several support rods, a set of upper and lower trays and a shade body. The main characteristics of the design are that the support rods and the upper and lower fixing sheaths are clamped separately and the curved hooks of the upper and lower sheaths can be pre-hooked to the upper and lower trays and integrated with the outer shade, which is easy for assembling and disassembling without removing the outer shade. It is much easier and faster to pre-enclose the upper and lower fixing sheaths, the outer shade of the upper and lower trays, the separate clamping of the support rods leading to great saving in production cost in the fabrication and assembly of support rods and fixing sheaths.

Abstract: A lighting unit includes a reflector, a plurality of light-emitting elements and a controller. The light-emitting elements are respectively provided on the reflector for a plurality of light-emitting regions. The controller supplies a periodic drive signal to each of the light-emitting elements, thereby defining a state of the light-emitting element. The lighting unit illuminates a display panel including a light modulating layer with light that has been emitted from the light-emitting elements. The controller supplies drive signals of substantially different types to at least two of the light-emitting elements.

Abstract: In a liquid crystal display device according to the present invention, an upper end portion of a lamp housing is fixed on a main supporter so that the lamp housing can be made to face a side edge of a light guide. Light that can cause bright lines is eliminated or minimized through absorption or scattering by a main supporter. The main supporter is also thermally insulating and is placed between the lamp housing and a liquid crystal panel. Further, a thermally conducting bottom cover is placed under the backlight. Therefore, heat generated from the lamp is effectively channeled away from the light guide to prevent liquid crystal panel deterioration. Still further, although the upper and lower surfaces of the light guide is tightly fit between the lamp housing and the main supporter, wrinkles on a sheet reflector are prevented because the sheet reflector is not stacked between the lamp housing and a lower surface of the light guide.

Abstract: A lamp crystal has a transparent body formed with an outwardly open bore and having an outer surface having a region with a matte finish, and a light-emitting diode fixed in the bore. The outer surface is substantially smooth and polished except at the region with the matte finish. The matte-finish region extends peripherally around the body.

Abstract: Disclosed are a backlight assembly and a liquid crystal display device using the same. A ratio of a pitch, which is an interval between the lamps for supplying light to an LCD panel, to a gap, which is a distance between the center of the lamps and an optical plate, is adjusted to thereby minimize the bright line that badly influences the image display quality, so as to display a high quality image.

Abstract: An adjustable element is part of an apparatus such as an automotive headlight which includes a support, and a security cap prevents undetected interference with the adjustment of that element, guaranteeing its inviolability. The adjustment is effected with a control member rotatable about a geometrical axis transverse to the axis of the support. The control member has an adjusting head accessible from outside the support. The security cap is mounted for movement in translation with respect to the support, parallel to the geometric support axis, and includes snap-fitting means co-operating with a zone of the support, to be engaged in response to this movement. The cap is put into a final snap-fitted position, in which it conceals the adjusting head, by a simple push.

Abstract: A lighting apparatus includes a plurality of light-emitting diodes emitting red, blue, and green light. The plurality of light-emitting diodes emit light beams and are arranged so as to emit the light beams toward a focusing point. A control circuit is provided for controlling the intensity of light emission of each of the light-emitting diodes emitting red, blue, and green light. A concave reflector is provided for reflecting and radiating the light focused from the light-emitting diodes to the focusing point so that the light is further focused or scattered. The apparatus also has a position-changing mechanism for changing a relative position of the concave reflector relative to the focusing point of the light-emitting diodes.

Abstract: A projection exposure apparatus includes a diaphragm controlling unit controlling one or more of an diaphragm, an iris diaphragm, and a relay lens system. In addition, the projection exposure apparatus also includes a line width calculator which calculates a bias, which is a difference between a line width in a dense part and a line width in an isolated part, based on information regarding a mask pattern, the wavefront aberration of a lens, the effective light source of an illumination optical system, the half-width of a laser, the temperature change in a projection optical system due to exposure, etc. When the bias is out of a tolerance range, the line width calculator calculates a correction value for the diaphragm of the projection optical system or a correction value for the effective light source of the illumination optical system in accordance with the bias which is to be corrected. Then, the diaphragm controlling unit is driven in accordance with the calculation results.

Abstract: A light projector includes a polarized light splitter 3 that splits unpolarized light irradiated from a light source 1 into p-polarized light and s-polarized light, and the p-polarized light and/or the s-polarized light are irradiated as vertical polarized light and/or horizontal polarized light, providing a driver with considerably improved forward visibility in comparison with a conventional headlight.

Abstract: Light is input into an incident surface portion from a fluorescent lamp, and most of the light propagates in repetition directions. Since a length of an emission portion of the fluorescent lamp is shorter than that of the incident surface portion, there are areas to which no light propagates and dark portions generate in the repetition directions of a string of prisms. Since these dark portion generate out of the display area, a display quality is improved.
