Embodiment Construction

[0017] Such as Figure 1 to Figure 3 The shown roadway lamp of the present invention comprises an upper shell 10, a lower shell 11 and a transparent member 15, and a light source 12 inside the cavity formed by the upper shell 10, the lower shell 11 and the transparent member 15, reflecting the Reflector 13 and electrical components 14 for light from light source 12 .

[0018] The reflector 13 is composed of two arc-shaped reflective surfaces symmetrically distributed above the axis of the light source 12, and the two reflective surfaces may also be planes. The two reflective surfaces are opposite to each other and inclined to form a V shape. The light source 12 is a metal halide light source, and other linear light sources can also be used. The light source 12 is placed horizontally, and the axis of the light source 12 is parallel to the symmetry axis of the two arc-shaped reflective surfaces of the reflector 13 . Since the light emitted by the light source 12 is perpendicu...

Abstract

A raceway lamp comprises a housing, a transparent member arranged on the housing, a light source arranged in the housing and the transparent member and a reflector for reflecting the light of the light source, wherein the reflector comprises two reflective surfaces which are arranged on two sides of the axis of the light source, opposite and inclined to be V-shaped. The invention has the beneficial effect that the light of the light source, reflecting by the reflector, is not overlapped with the light of the light source, directly illuminates on the two sides of the light source and the ground, thereby improving the utilization of the light, reducing the number of the light source having a certain distance, simultaneously because the light reflected by the reflector does not pass through the light source, the temperature of the light source is reduced, and the service life of the light source is prolonged.

Description

technical field [0001] The invention relates to a lead-in device and a lighting fixture, more specifically, to a roadway light and a mining explosion-proof roadway light. Background technique [0002] Existing roadway lights include housing, transparent parts, light source, reflector and electrical components. The reflector includes two arc-shaped reflective surfaces with the light source as the axis of symmetry and opposite openings. The light emitted by the light source and the reflective surface reflect the light source. The light rays overlap each other, and a large amount of energy is lost, resulting in a limited longitudinal light distribution distance along the roadway. At a certain distance, more roadway lights need to be installed. At the same time, the light reflected by the reflective surface passes through the light source, which increases the heat of the light source. The service life is greatly reduced. In addition, the electrical components of existing lamps...
