Problems solved by technology

[0009] Obviously, although the last two glare phenomena caused by street lights on the expressway have no clear design specifications and detection indicators, no effective control method has been found so far.
However, under traditional lighting methods (especially on wide roads), the basic road sections do exist, and they also belong to the category of direct glare, which will cause strong interference to drivers driving at night

Abstract

The invention is applicable to the technical field of road illumination and provides a multi-dimensional composite light distribution street lamp which comprises multiple illumination subsystems withdifferent dimensions and an intelligent control system. Optical light distribution and structural light distribution are used, according to the function of optical light distribution, light energy isprojected as far as possible with the minimum loss, and the problem that illumination of the street lamp to the center of a road is insufficient is solved. According to the function of structural light distribution, coordination with the function of optical light distribution is achieved, the light energy is utilized to the greatest extent with the minimum luminous efficiency loss, and the problemof glaring of the street lamp is solved. According to the street lamp, light sources of the illumination subsystems at all low lamp positions and a control element are integrated into one lamp body,the solid street lamp is formed, and solidification and integration of the illumination subsystems are achieved. The street lamp has the beneficial effects of avoiding glaring, being high in illumination efficacy, achieving self-adaptation control and the like. The street lamp has a landscape illumination function, has effects of ensuring traffic safety, improving transportation efficiency and beautifying city environment, and ensures traffic safety.

Description

technical field [0001] The invention belongs to the technical field of road lighting, in particular to a multi-dimensional composite light distribution street lamp. Background technique [0002] In road lighting, glare has always been an important evaluation index. Glare refers to visual disturbances that have an unsuitable range of brightness in the field of view and extreme brightness contrasts in space or time that cause discomfort or reduce visibility. [0003] CJJ45-2015 clearly stipulates that the design and detection index for limiting glare is the threshold increment, and the threshold increment is used as the index to set the upper limit for glare, which is an important factor for evaluating the quality of road lighting. [0004] Studies have shown that there are many ways to reduce glare, but there is a contradiction: all measures to reduce glare have their cost - the loss of light efficiency of the street lighting system. Therefore, the essence of the need for g...
