Abstract: A lamp brightness remote controlling device is provided for regulating a brightness level of a lamp correspondingly provided with a wireless receiver unit, and includes a first central processor, to which an ambient brightness detector, a setting key, and a wireless transmitter module are electrically connected. The first central processor compares a user-set brightness level set by a user via the setting key with an ambient brightness detected by the ambient brightness detector, computes, and then outputs a comparison signal to the wireless transmitter module for transmitting to the wireless receiver unit on the lamp, so that a luminance of the lamp is automatically regulated to always keep a working environment at the user-set brightness level.

Abstract: A shielding-type rack upright post includes a first upright plate and a second upright plate which are spaced at an angle, each of the first upright plate and the second upright plate having a plurality of combination holes arranged at intervals vertically, wherein a first shielding plate is spaced at an interval from an external surface of the first upright plate and is parallel to the first upright plate, and a second shielding plate is spaced at an interval from an external surface of the second upright plate and is parallel to the second upright plate. The first and second shielding plates are used for shielding the combination holes of the first and second upright plates, and an end portion of a transverse beam engaged with the combination holes; and also for reinforcing the rack upright post structure.

Abstract: A bulb structure of assembling-type car lamp includes a lamp housing and a bulb unit. The bulb unit includes a mounting base, a bulb holder, and a bulb. The mounting base includes electric pins, a forward raised seat, and a rearward protruded annular ring portion. The annular ring portion is externally provided with anti-slip ribs to facilitate easy turning and assembling of the bulb unit to the lamp housing. The bulb holder includes a holding seat and an adjusting seat connected to the mounting base and the bulb, respectively; and the bulb is electrically connected to the electric pins. By adjusting the adjusting seat relative to the holding seat, the bulb can be adjusted in position and focal length. A cover plate is closed to a rear open end of the annular ring portion to isolate joints of the bulb and the electric pins from external air, dust and water.

Abstract: An assembling-type car lamp includes a lamp housing and a bulb unit. The lamp housing is provided with an assembling hole, and the assembling hole is provided on an inner wall surface thereof with a plurality of circumferentially spaced ribs to thereby define a notch between any two adjacent ribs. The bulb unit includes a base and a bulb mounted to the base. The base includes an end plate and a forward raised seat. The raised seat is provided on an outer wall surface thereof with a plurality of circumferentially spaced guide blocks located corresponding to the notches, such that an annular space is defined between the end plate and the guide blocks. The bulb unit can be removably assembled to the lamp housing by moving the guide blocks through the notches into the assembling hole and turning the bulb unit for the ribs to locate in the annular space.

Abstract: A lighting fixture includes a bottom frame having an inner bottom face and a first opening corresponding to the inner bottom face; a planar reflecting plate laid on the inner bottom face of the bottom frame; a plurality of lighting units mounted on the inner bottom face within the bottom frame to locate on the planar reflecting plate; a light diffusion sheet laid atop the bottom frame to cover the first opening; and a top frame configured corresponding to the bottom frame and defining a second opening corresponding to the first opening. The top frame is assembled to the bottom frame with the light diffusion sheet clamped therebetween to thereby close the second opening of the top frame. The planar reflecting plate allows the lighting fixture to be low-profile, and the light diffusion sheet uniformly distributes the light produced by the lighting units while eliminates glares and blocks off dust.

Abstract: A room temperature raising apparatus includes a housing defining a receiving space divided into an air intake chamber and a convection chamber communicable with each other via a through hole; a heating unit mounted on a bottom of the convection chamber to heat cold air into hot air; an airflow guiding device located over the convection chamber and including a plurality of spaced manifolds communicating the convection chamber with an air outlet; and a forced convection unit mounted in the air intake chamber for forcing external cold air into the air intake chamber via an air inlet and then into the convection chamber via the through hole. The hot air produced in the convection chamber flows upward due to a convection effect and is driven by the forced convection unit to flow through the manifolds and be discharged via the air outlet.

Abstract: A lighting tube adapting device includes an insulating base having two through holes for receiving two tube pins of a lighting tube, and an adapting unit including two adapting seats, two adapting members, and two bridge members. The adapting seats are spaced in the insulating base and define two hollow spaces separately communicating with the through holes on the insulating base. The adapting members are electrically conducting and mounted in the hollow spaces of the adapting seats, and respectively include a first sleeve portion for receiving one tube pin and a second sleeve portion sidewardly communicating with the first sleeve portion. The bridge members are electrically conducting, and respectively have a first adapting pin for inserting into the second sleeve portions and a second adapting pin for inserting into two pin insertion holes on a socket. Therefore, the lighting tube is electrically connected to the socket via the adapting device.
