Abstract

The invention discloses a locomotive headlamp. The locomotive headlamp comprises a light source and a radiator. The light source comprises at least one LED lamp. The LED lamps are installed on the element face of a circuit board. The radiator is arranged on the back face of the circuit board so as to cool the light source. The locomotive headlamp further comprises lenses for condensing light emitted by the LED lamps, and the lenses correspond to the LED lamps. The LED lamps are located on the focal planes of the lenses so as to emit parallel or approximately-parallel light beams through the lenses. The locomotive headlamp is simple in structure, the exit direction and illuminance distribution of light can be effectively controlled without an additional auxiliary device, remote illumination can be achieved, the problems that direct illumination is short in distance and low in illuminance are solved, and the energy utilization rate of an optical system is high.

Description

technical field [0001] The invention relates to the field of lighting devices, in particular, to a motorcycle headlamp. Background technique [0002] Existing locomotive headlamp mainly is made up of light source, reflector cup, power supply equipment and cooling device. The light source is usually incandescent lamp and HID lamp (metal halide lamp, xenon lamp). The incandescent light source has defects such as low illumination, high energy consumption, short range, and short life. The HID lamp light source is discharged through the arc in the lamp tube, combined with the inert gas or metal vapor filled in the lamp tube to produce strong light, but because the filling in the lamp is a harmful substance, careless handling will cause environmental pollution and affect the environment. people's health. Moreover, HID lamps have defects such as high-voltage operation, high energy consumption, low light efficiency, large volume, poor shock resistance, long start-up time, and sho...
