Abstract: The invention is an illumination system comprising a semiconductor light source module. The illumination system comprises a reflector comprising a curved reflective surface, a holder coupled to the reflector, and a semiconductor light source module comprising a first light-emitting unit and a second light-emitting unit. The holder comprises a second holding section and a first holding section disposed between the reflector and the second holding section. The semiconductor light-source module is disposed on the second holding section to face the curved reflective surface. An angle between at least a light-emitting unit and at least a part of the first holding section is formed and ranges from 145 to 175 degrees.

Abstract: A LED vehicle lamp structure installed in a vehicle lamp assembly comprising a housing, a lens, and a reflector is disclosed to include standing boards each having a top edge, a bottom edge, a height defined between the top edge and the bottom edge, and LEDs. By means of the arrangement of the LEDs on the standing boards to match with the heights of the standing boards between the respective top edges and the respective bottom edges, the light-emitting heads of the LEDs constitute an array that fits the variation of the curvature of the reflector and lens of the vehicle lamp assembly, thereby greatly lowering the cost and the manufacturing difficulty of the vehicle lamp assembly.

Abstract: A LED lamp having a housing with two locating members on the inside, a circuit board mounted on the locating members and kept spaced above the bottom wall of the housing at a distance, LEDs installed in the circuit board, and a lens, which is covered on the housing over the circuit board and the LEDs and has accommodation holes in the inside wall thereof for accommodating the LEDs respectively such that the lens and the housing keep the circuit board from sight and, the lens allows the light of the LEDs to pass to the outside through the thin wall thickness area of the inside wall corresponding to the accommodation holes.

Abstract: An electronic ballast, The ballast use voltage controlling the energy storage capacitor, Furthermore, the electronic ballast continuously detects the current value and the voltage value of the HID lamp, change the pulse-width signal according to the detection result to control the HID lamp within a stable working current.

Abstract: A lamp structure is constructed to include a transparent opencell housing with a predetermined wall thickness, the housing comprising an inner mirror layer and an outer mirror layer respectively coated on the inner and outer surfaces thereof, a light admitting face in the outside peripheral rim thereof neighboring the mirror layers, and a light source installed in a lamp socket formed integral with the housing and controlled to emit light into the predetermined wall thickness, for enabling light rays to be mutually reflected between the mirror layers and guided toward the light admitting face in the outside peripheral rim of the housing to form a light ring.
