Abstract: A hand-held power tool comprising an output shaft rotatable around a tool axis of rotation, a tool housing portion radially disposed relative to the output shaft, an illuminating element for illuminating a work area of the tool, a lens positioned adjacent the illuminating element, and a cover that secures the lens and the illuminating element to the tool housing portion. At least a portion of the cover is closer to the axis of rotation than the lens is to the axis of rotation.

Abstract: A luminaire including a housing and a multi-purpose mounting feature formed at an interior of the housing, where the mounting feature is configured to receive and retain a mount for mounting of the luminaire on a vertical surface, and where the mounting feature is configured to receive and retain an electrical cord, to direct the electrical cord at least partially along a length of the luminaire, and to conceal the electrical cord from view.

Abstract: The invention relates to a display apparatus, particularly to structure of LED display modules. The invention could be implemented through a LED matrix display module with high luminance area ratio comprising an injection molding unit and a printing board fitted therewith, wherein, LEDs are regularly arranged in a matrix on said printing board, and each pixel dot is correspondingly provided with a reflecting cavity on said molding unit, with the reflecting cavity expanding gradually from the inside section (close to the display surface). The circumference of the inside section of the reflecting cavity forms a closed and smooth circular curve. The invention is characterized in that, the circumference of the outside section of the reflecting cavity forms a closed and smooth curve which is a square with round corners, and the side face of the reflecting cavity is a smooth and cured surface.

Abstract: A retrofit fixture for installation into an existing recessed fluorescent strip fixture in an inverted T-bar grid ceiling. The retrofit fixture length is less than the length of the ceiling opening, except for hangar tabs which extend from a flange along a longitudinal edge. The fixture may be hung from the ceiling grid members by the tabs while wiring connections are made, and then swung into place. Lamps having a combined length greater than the length of the ceiling opening may be used by placing the lamp holders in a staggered arrangement.

Abstract: The present invention provides a display assembly including a display screen, a planar light guide, a light source, a light bar, and a frame. The frame is integrally molded with the planar light guide to form a single component, wherein the top and said bottom of the light guide is not obstructed by the plastic frame. The planar light guide is disposed above the display screen and provides mechanical support of the display. The light bar is disposed between the planar light guide and the light source, and acts to couple light from the light source into the planar light guide.

Abstract: An emergency flashlight includes a handle portion and a rotary portion mounted on the handle portion for rotation about a rotary axis. An elongate swing shaft has one end mounted to the rotary portion to rotate therewith, the other end extending substantially radially away from the rotary portion. A light-producing means is mounted on the swing shaft adjacent the end remote from the rotary portion. Inside the handle portion are located generating means and gear means, allowing electrical energy to be created by swinging the handle in a circular motion, thereby causing the swing shaft and the rotary portion to rotate with respect to the handle portion. Conductive means such as wires are provided to carry the electrical energy to the bulb.
