  • Publication number: 20040141322
    Abstract: A backlight module for liquid crystal display includes a casing having a bottom wall and a circumferential side wall extending from the bottom wall to define an open top. A light guide plate is attached to the side wall and spaced from the bottom to define an interior space therebetween. A light diffusion plate and a protection plate are respectively mounted to the top opening of the casing. A plurality of lamps are arranged in the interior space and spaced from each other. First vent holes are defined in the side wall of the casing to allow air to flow in and out of the interior space for removing heat generated by the lamps. Second vent holes are defined in the side wall and are paired of which the second vent holes are opposite to each other. A triangular channel is formed between the second vent holes of each pair by two inclined side walls. Air is allowed to flow into the channel via one of the second vent holes, through the channel and eventually leaving the channel via another second vent hole.

  • Patent number: 5764493
    Abstract: A back lighting device for use with a palm top image scanner includes a body inside which a light generating member is arranged to project light through a window on which a film to be scanned is placed so as to project the image on the film to the image scanner. The window has a frosted surface to support the film thereon so as to eliminate the interference ring occurring therebetween. The window is provided with a circumferential step so as to define a recessed window area for receiving therein a film holding plate, made of a light transmitting material, for firmly holding the film on the window. The film holding plate may also be provided with a frosted surface to avoid the occurrence of the interference ring between the film holding plate and the window.

  • Patent number: 5676444
    Abstract: A neon light box which uses a C.C.F.L. and a light guide to provide a more uniform and brighter light source than in prior art devices. The neon light box has ferro-metallic bars on the window and the top cover, to which a transparent cover with magnetic bars fixed thereon is attached to provide a space for displaying an advertisement slide. The light box uses metal bars mounted to a top cover and window to compensate for the height difference between the top cover and the window, so as to create a smooth surface when used in conjunction with a transparent cover.

  • Patent number: 5467172
    Abstract: A transparency adaptor for use in a flat bed type image scanner. The transparency adaptor which is to be displaced on the image window of the image scanner to project uniform "planar" light through a light-transmittable medium on which image to be scanned is printed so as to eliminate the need of complicated and sophisticated line light source upon the scanning window includes a shallow panel like casing inside which a pair of cold cathode fluorescent lamps (CCFLs) are disposed in a spaced and opposite manner to project light toward each other. A plate-like lighting guide is disposed between the CCFLs to uniformly distribute the light through a given planar area. A reflection sheet is provide to direct the light generated by the CCFLs toward a desired orientation. Light diffusers may be disposed along the out-going path of the light to more uniformly distribute the light through the given area.
