Lamp

Abstract

The invention discloses a lamp which is mounted on a road, the road comprises lanes opposite in advancing direction, and the lanes are separated by a central line. The lamp is arranged at an elevated position of the central line, and light emitted by a lighting component in the lamp and used for lighting the preset lane of the road is evidently controlled in the advancing direction of the preset lane. An optical component is arranged on the outer side of the lighting component of the lamp and used for reflecting the light to the preset lane to form a first emergence area and a second emergence area. The lamp mounted at the central line deflects toward one of the lanes by a deflection distance and the lighting component inclines towards the other lane by a correction angle to enable the first and second emergence areas to be different in light shape. Therefore, the lamp can be applied to lighting demands of different light shapes and especially applied to lighting in tunnels.

Description

technical field [0001] The invention relates to a lamp, in particular to a lamp that can be applied to lighting requirements of different light shapes. Background technique [0002] A light-emitting diode (Light-Emitting Diode, LED) is a semiconductor electronic component that can emit light, and it emits light by converting electrical energy into light energy. Lamps that use light-emitting diodes to emit light have the advantages of high luminous efficiency, long life, unbreakable, and fast response, so they are gradually replacing traditional lamps. [0003] At present, the lighting light shape produced by street lamps using LED light sources is usually a long ellipse or a light shape close to a long rectangle, and the distribution of these two light shapes is symmetrical in the X direction or the Y direction. For example, Taiwan Patent Publication No. I312398 "Street Lamp with Oval Light-Emitting Diode" discloses that the ratio of the light shape scattered by the long ax...

[0004] However, if the street lamp using the above-mentioned LED light source is installed in the tunnel, because the installation position is offset from the center of the road surface, and because the LED light source street lamp has a symmetrical light shape in the X direction or the Y direction, it will illuminate the lanes on both sides of the road. The light on the
