The invention provides a self-adaptive high-low-beam integrated LED multi-module headlamp. The headlamp comprises a high-low-beam following self-adaptive light type control system, a light compensation system and a color temperature control system; the high-low-beam follow-up self-adaptive light type control system comprises an LED light source module array which comprises a plurality of LED light source modules, more than two parallel LED light source modules of which the optical axes are parallel to the center of an automobile body form a straight driving light source, and more than one LED light source module arranged outside the straight driving light source forms a steering light source, wherein the included angle formed between the optical axis of each LED light source module and the center of the automobile body is an acute angle; the included angles formed between the optical axes of the LED light source modules of the steering light source and the center of the automobile body are sequentially increased from inside to outside. According to the self-adaptive high-low-beam integrated LED multi-module headlamp, due to the fact that multiple independent LED light source modules are arranged to serve as the headlamp, when an automobile straight drives or turns, high-low-beam light spots during straight driving and light type following during turning are achieved by controlling the different LED light source modules to be lighted to obtain the better illumination angle.

A LED lighting fixture includes a cavity receiving a light guide board, and a plurality of LEDs mounted within two reinforcing parallel grooves formed in the light guide board along the length of corresponding opposite lateral sides. The light guide board further includes a clear base portion made of a light transmissive material, and a continuous reflective layer disposed over a surface of the clear base portion, the reflective layer having a portion protruding into the clear base portion. Light from the LEDs is injected transversely into the inside of the light guide board for reflection by the reflective layer to be ejected from the lighting fixture through a surface of the light guide board.

A structure of overhead lamp and mounting bracket for constructional vehicle has developed to tilt the illuminating angle by controlling the position of slits at the lateral sides of bracket. The lamp is securely fixing at the controlled position at one of 4 positions and the position controlling slits. The main case is securely fixed to the bracket by installing a connection screw and a hinge bolt for restricting unwanted rotation of the hinge bolt. Accordingly, since a position controlling rib having a position controlling slit is extended rearward from side supporters, the illumination angle can be controlled within a greater range. The main case can be supported at 4 points through the plurality of position controlling slits. Furthermore, by fitting the connection screw with an outer circumferential recess of a hinge bolt fastening lever, rotational separation of the hinge bolt and change of the illumination angle of the main case can be prevented.

A lighting unit is provided and includes a cup body, a substrate, a first conductive wire connector and a second conductive wire connector. The cup body has a light emitting surface, a first end portion, and a second end portion. The substrate is located in the concave accommodating cavity of the cup body. A lighting element is located on the substrate, and has a light emitting direction toward the light emitting surface. The first and second conductive wire connectors are respectively located at two sides of the substrate in the accommodating cavity. A portion of the first conductive wire connector protrudes from the surface of the first end portion to form a first male connection terminal. The second conductive wire connector is recessed in the surface of the second end portion to form a first female connection terminal.
