Bridge road lamp enabling low-height illumination

Abstract

The invention provides a bridge road lamp enabling low-height illumination. The lamp comprises a light distribution system, a heat dissipation device, a drive circuit, a lamp shell and a mounting bracket, wherein the light distribution system comprises a parabolic reflector and a luminous unit; the heat dissipation device and the lamp shell are fixed and connected with the light distribution system and the drive circuit in the lamp shell; the drive circuit makes the luminous unit emit light; the parabolic reflector comprises three parabolic plates which are connected in turn to form a plane; an angle alpha is formed between two adjacent parabolic plates; a luminous unit is arranged on the focus of each parabolic plate; and the reflecting surface of the parabolic plate faces to the road surface. Through the invention, the road surface is effectively illuminated by a low lamp, and uniform light distribution is achieved; meanwhile, the mounting height of the lamp is low, the work is reliable, the maintenance is easy, a beautifying effect is realized, the materials are saved, and the riding comfort is guaranteed due to the relatively low glare; and on the condition of meeting the requirements on illumination level and uniformity of road illumination, overall power consumption of the lamp is reduced.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a bridge road lighting fixture capable of lighting at low heights. Background technique [0002] With the deepening of China's urbanization and infrastructure construction, bridges have developed from simple pedestrian bridges and overpasses to more complex river-crossing and even sea-crossing bridges, with increasingly diverse forms and functions. Most bridges in cities have the functions of motor vehicle lanes, non-motor vehicle lanes, pedestrian passages and even railway passages. The lighting design of such bridges usually follows the road lighting design specifications, extending street lights from the street to the bridge body and running through the entire bridge body. Although this approach meets the requirements of functional lighting, it also has a huge impact on the overall lighting effect of the bridge. [0003] At present, the traffic density of urban viaducts, overpasses and h...

Although this approach meets the requirements of functional lighting, it also has a huge impact on the overall lighting effect of the bridge

[0003] At present, the traffic density of urban viaducts, overpasses and highway entrance and exit ramps is high. The installation and maintenance of traditional high-pole lighting fixtures requires high-altitude operations, which is risky; the height of the

At the same time, excessively high street lights will consume more building materials and have lower lighting efficiency, and the glare it brings will destroy the overall lighting effect of the bridge

Also during the day, too high street light poles will also affect the overall landscape effect of the bridge
