Abstract

The invention relates to a steering lamp and belongs to the technical field of illumination. The steering lamp comprises a rear shell, a front cover and a light-emitting assembly. The light-emitting assembly comprises a light guide bar, a point light source and LED lamps. Light reflecting bases are fastened to the rear shell. A mounting base is formed on the light reflecting bases in a protruding mode. The light guide bar is mounted on the mounting base. A bent part is arranged at one end of the light guide bar and inserted into the mounting base. A chamfer is arranged outside the joint of the light guide bar and the bent part. The point light source is mounted in the mounting base and directly faces the end of the light guide bar. Multiple concave mirrors are distributed on the light reflecting bases on the two sides of the mounting base, and the mirror surfaces face the light guide bar. Multiple light holes are formed in the two sides of the mounting base. An LED board is mounted in the mounting base, the multiple LED lamps are mounted on the LED board, the LED lamps are located in the light holes and arranged corresponding to the concave mirrors, and the light guide bar is made of composite with reasonable prescription. The steering lamp is simple in structure, convenient to mount and good in light effect, comprehensive performance of the light guide bar is good, and the service life of the steering lamp is long.

Description

technical field [0001] The invention belongs to the technical field of lighting, and relates to a lamp, in particular to a turning lamp. Background technique [0002] Patent CN102147090A discloses a lamp for a vehicle, in which a plurality of LED light sources are arranged on a single substrate, and a structure with a small number of components and a low price is used to brightly illuminate a wide area around the vehicle. In turn indicators, multiple LED light sources are arranged on a common substrate. A light guide lens is formed elongately in the arrangement direction of the light sources, the mounting piece is installed on the lamp body by screws, and the substrate is erected and locked on the erection locking pin and the erection locking claw of the light guide lens. The same number of incident parts and reflective surfaces as the light source are formed on the light guide lens, and the vertical incident light is horizontally reflected and emitted from the light-transm...
