Road LED lighting lamp light distributing method

Abstract

The present invention relates to a light distribution method for road LED lighting lamp, which is characterized in that: step 1, measuring the width (w) of a channel, the number of lane and lighting height (h); step 2, selecting transverse light distribution mode to determine transverse beam angle (theta) and manufacture the lighting lamp to be needed at the basic section of the channel; step 3, adopting the light distribution mode of symmetrical double sides and middle light distribution to determine the transverse beam angle theta 3 and manufacturing the lighting lamp to be needed according to the transverse beam angle; step 4, determining the longitudinal beam angle (psi) of the lighting lamp and the longitudinal light distribution spacing (s) of the channel. The present invention has the advantages by reasonably selecting lighting lamp according to the condition of the channel, reasonably distributing the transverse and longitudinal light distribution modes of the lighting lamp, effectively utilizing light resource, meeting the lighting requirement, ensuring safety of pedestrian and vehicle, and saving cost.

Description

technical field [0001] The invention relates to a light distribution method for lighting lamps, in particular to a method for determining the arrangement of LED lighting lamps for roads in tunnels. Background technique [0002] The lighting arrangement of street lights has a good visual guidance for drivers and plays a certain role in beautifying the city lighting. The lighting arrangement of roads and tunnels includes middle lighting, single-side lighting, and single-sided mid-side lighting. , Double-sided staggered lighting, bilateral symmetrical lighting and bilateral symmetrical plus middle lighting. At present, there are a considerable number of roads and tunnels in my country that have unreasonable road lighting designs, and cannot select suitable lighting lamps according to the specific conditions of each tunnel, and arrange lighting lamps according to appropriate spacing; some beam angles θ are too large, and the lighting lamps The lighting range is too wide, resulti...

AI Technical Summary

Problems solved by technology

At present, there are a considerable number of roads and tunnels in my country that have unreasonable road lighting designs, and cannot select suitable lighting lamps according to the specific conditions of each tunnel, and arrange lighting lamps according to appropriate spacing; some beam angles θ are too large, and the lighting lamps The lighting range is too wide, resulting in a waste of light resources. Some beam angles θ are too small, and the lighting range of the lighting is too narrow, which cannot illuminate the entire road surface and cannot meet the lighting requirements.

At present, it is not possible to determine a reasonable beam angle of the lighting according to the tunnel conditions, and the lighting should be reasonably configured according to the beam angle

[0003] The main problem of the existing technology: it is still impossible to choose the lighting reasonably according to the tunnel conditions, and the horizontal and vertical arrangement of the lighting is unreasonable, or it causes energy waste, or cannot meet the lighting requirements
