Abstract: An illuminating device is mounted on top of or below a light steel frame and includes at least one one-piece elongated shade in which a bowl-shaped mirror reflector is mounted. A fluorescent tube is mounted in the shade and longer than one of a plurality of sections of the light steel frame. A wing extends horizontally from each of two lateral sides of the shade. An extrusion ridge is formed on a top side of the shade. Two shield boards are mounted in each section of the light steel frame extended across by the shade. An edge of each shield board rests on one of the wings. First and second snap fasteners are selectively engaged with the extrusion ridge. The first snap fastener can fix an electronic stabilizer on the extrusion ridge. The second snap fastener can fix the illuminating device to a longitudinal beam of the light steel frame.

Abstract: A heat sink attached externally on a bottom portion of a portable computer has the heat sink placed at a rear lower aspect of the portable computer; the present invention is characterized that the heat sink is a flat casing; at least one fan is installed inside the heat sink; an air inlet is disposed at the upper aspect of the fan; an air outlet is disposed at the front aspect of a bearing plate on the front aspect of the fan; a current guide board is disposed at the lower aspect of the fan; according to the abovementioned structure, when being used, the air current enters from the air inlet and discharges outwardly from the air outlet thereby allowing the cooling air current to enter from the bottom portion of the portable computer for heat dissipation.
