Abstract: The instant disclosure relates to a lighting device, which includes a lighting module, a reflector, a light-guiding member, a main body, and a cover. The lighting module includes a base plate and a plurality of light-emitting units mounted on the base plate. The reflector has at least one reflective surface proximate to the base plate. The cross-section of the reflector gradually decreases in a direction toward the base. The light-guiding member is disposed between the lighting module and the reflector. The light-guiding member has a polarizing portion for reflecting light emitted from the light-emitting units. The base plate is disposed on one end of the main body. The cover is selectively disposed on the main body. Thus, an omni-directional lighting device is presented.

Abstract: The instant disclosure relates to a light bulb, which includes a base, a conducting cap arranged on one end of the base, a heat-dissipating member disposed on the opposite end of the base, and a lamp cover. The heat-dissipating member has a wedged structure, and a plurality of inclined surfaces are formed adjacently thereon. A plurality of LEDs is disposed on the inclined surfaces, and the lamp cover is arranged over the wedged structure and the LEDs. The instant disclosure uses the LEDs to replace tungsten filament as the light sources, and arranging the LEDs on the wedged structure of the heat-dissipating member. Thereby, the light bulb can have higher heat-dissipating rate.

Abstract: A frame module includes a frame strip, a light emitting diode (LED) bar, and a fastener. The frame strip has a heat-dissipating portion, two elastic arms extended in one direction from the two edges of the heat-dissipating portion, and two pressing portions inwardly protruded form the two elastic arms. The heat-dissipating portion, the two elastic arms, and the two pressing portions define an accommodating trough. The LED bar has a printed circuit board (PCB) and a plurality of LEDs mounted on the PCB. The PCB is arranged in the accommodating trough of the frame strip and clamped between the heat-dissipating portion and the two pressing portions. The fastener is fixed on the two elastic arms. Thus, the heat generated form the LED bar is conducted by the LED bar directly contacting the frame strip. Besides, the instant disclosure also provides a lamp.

Abstract: A disk drive mounting structure includes a casing, the casing having positioning units disposed in two opposite sidewalls thereof at different elevations, a plurality of carrier plates respectively hooked in the positioning units and adapted for holding disk drives in the casing at different elevations, a plurality of holding down frames respectively pivoted to the positioning units at one side wall of the casing and adapted for holding down the corresponding disk drives on the carrier plates, and a plurality of locking handles respectively pivoted to the positioning units at one side wall of the casing and adapted for locking the holding down frames and the disk drives.

Abstract: A CD-ROM rack includes a rack body adapted to support computer readable disk drivers/players on the inside at different elevations, the rack body having transverse sliding tracks at two opposite side panels thereof, a plurality of retaining spring plates respectively riveted to the side panels of the rack body and adapted for locking loaded computer readable disk drivers/players, and a plurality of elongated holding down plates respectively inserted into the transverse sliding tracks to hold down the retaining spring plates in the locking position.

Abstract: A PC board support is disclosed to include a hollow support shell adapted to support a PC board above a frame, a spring mounted inside the support shell, the support shell having a top opening, a top neck, and a retainer head at the top of the top neck, and a slide supported on the spring inside the support shell and moved along a vertical sliding groove at the retainer head and top neck of the support shell in and out of the top opening to unlock/lock the PC board.
