  • Publication number: 20120262946
    Abstract: The present invention provides a backlight module and a housing unit structure thereof. The backlight module includes a back plate having a first edge, a second edge, a third edge and a fourth edge. The edges of the back plate are provided with a housing including a plurality of housing unit structures. The housing unit structures have a strip shape or an L-shape, respectively, and are disposed on the back plate by connecting or spacing a distance to each others to assemble into a housing. The backlight module uses an adjustable modular design to adjust the number of the housing unit structures for being suitably applied to various backlight modules with different sizes. Except for reducing the use of material, the development cost and time of the backlight module can be saved.

  • Publication number: 20110155511
    Abstract: In a safety device for an elevator, on one car door among a pair of car doors, a light-emitting/light-receiving unit is disposed facing downward at an upper end position of a vertical line separated by a predetermined distance from an end face in a closing direction, which is to abut the other car door, toward the side of the other car door, and a first reflecting member is disposed facing upward at a lower end position of the vertical line. A housing space that houses the light-emitting/light-receiving unit in a state where both car doors are closed is formed on the other car door, and a second reflecting member is disposed facing upward at a bottom portion of the housing space and extends from the same position as an end face in a closing direction of the other car door toward the back of the housing space.
