Abstract: An LED projector for emitting light spherically in 180° includes a driving power supply; a projector body; a lamp seat, with three slanted protruding surfaces, being placed inside the projector body, the three slanted protruding surfaces being distributed circularly with a first angle of 120° between any two slanted protruding surfaces; three LED lamps connected to the lamp seat, one LED lamp on each slanted protruding surface; a reflector plate, with a protrusion element for receiving the lamp seat, attached to the projector body, the protrusion element having three projection holes for receiving the LED lamps; a spherical transparent lampshade for covering projector body; and a lampshade frame. The LED projector has a simple and rational configuration with easy assembly, and has large range of irradiation, good light condensation effect and balanced light.

Abstract: An LED projector capable of emitting light in 180°, which includes a projector body; a power supply; a reflector cup; a lampshade; and a lampshade frame; a lamp seat having a pair of symmetrical inclined planes, an angle between the vertical center lines of the two inclined planes is between 30° and 90°; and two integrated LED lamps, each LED lamp being fixed on an inclined plane of the lamp seat, wherein the reflector cup has a bulge, and the bulge has two light projection holes for receiving the integrated LED lamps. The LED projector has a simple and rational configuration with easy assembly, and has large range of irradiation, good light condensation effect and balanced light.

Abstract: It is one kind of hand-held electric power tool with safety shift device, including housing assembly, motor, end cap of gear box, gear box, output shaft, final-stage rack wheel, final-stage pinion, gear pin roll, safety shift pin roll, gear knockout plate, gear synchronous spring, safety shift spring, safety push rod, stop pin, variable-speed pinion axis, variable-speed rack wheel, big bevel pinion, bevel pinion and grinding wheel shield. Among which, the gear pin roll and safety shift pin roll are installed within the gear box in parallel, the gear knockout plate is connected with final-stage rack wheel and final-stage pinion, the gear synchronous spring is installed on the gear pin roll while the safety shift spring is installed on the safety shift pin roll. This new practical hand-held electric power tool with safety shift device is characterized by low-speed gear automatic recovery function and the dangers of disoperation will be avoided, being safe and convenient.
