Abstract: A stator structure for an electric motor unit, includes a main body; an insulated member mounted on the main body; a plastic body disposed on the insulated member; a copper circuit path disposed on the plastic body; a plurality of first and second windings, each being wound on the main body, consisting of a metal wire and a coated sheath enclosing the metal wire and includes first and second leading ends extending through the insulated member so as to be soldered on the copper circuit path; and several power conducting wires, each having a distal section soldered with the corresponding second leading end of a respective one of the second windings.

Abstract: An angle adjusting mechanism for a streetlamp includes a housing connected with a lamp, and an angle positioning board and a lamppost sleeve installed in the housing. The angle positioning board has a first positioning hole and a plurality of second positioning holes. The lamppost sleeve has a first positioning tube and a second positioning tube. Through pre-arranging corresponding angles of the angle positioning board and the lamppost sleeve, the illumination angle of the lamp is capable of being adjusted. Moreover, the lamppost sleeve and the angle positioning board are fastened by screws, so the illumination angle of the lamp and the housing can be rapidly adjusted through loosening or fastening the screws.

Abstract: A light guide illumination device is provided. The light guide illumination device includes a light guide shade configured with a spherical shape. The light guide shade includes a light inputting aperture and a light outputting aperture. The light inputting aperture is adapted for receiving a light emitting unit therein. The light emitting unit is adapted for emitting a light therefrom. The light guide shade has an inner spherical surface serving as a light reflecting surface. The light reflecting surface is adapted for reflecting the light for one or more times and outputting the reflected light out from the light outputting aperture. The outputted light is then projected from the light outputting aperture to the ambient space.

Abstract: A gain structure for improving a luminance of a road lamp is disclosed. The gain structure includes a plurality of lamps and a plurality of reflecting shades. The lamps are secured to an end surface of a body of the road lamp. The lamps arranged at an outer side are arranged with an oblique angle toward the lamp arranged at a middle side of the lamps, so that the illumination range can be enlarged. Each of the reflecting shades is provided for accommodating a plurality of light emitting units therein for improving the efficiency of each of the light emitting units. In such a way, the present invention is adapted for providing a solution for the problems of the conventional technology, and is further adapted for improving the entire light emitting efficiency and lowering the glare.

Abstract: An improved lamp holder for a high intensity discharge (HID) lamp includes a base and a metallic positioning member, in which the metallic positioning member includes a vibration-damping clamping ring having three extension feet extending outwards and downwards from a bottom rim of the clamping ring and inserted into their respective corresponding insertion slots of the base; and the clamping ring clips a lamp tube.
