Medium-lighting-position multi-dimensional road lighting system

Abstract

The invention provides a medium-lighting-position multi-dimensional road lighting system consisting of illumination components in dimensions, wherein the illumination components comprise a low-lighting-position backlighting illumination component, a medium-lighting-position orthodromic illumination component, a medium-lighting-position transverse illumination component, a vertical illumination component and a display illumination component which respectively undertake the multiple tasks of roadway illumination, space lighting, illumination in complex weather conditions, indication / landscape lighting and real-time graphic and text display lighting. Each component is independent and can be adjusted independently in the lighting functions, photochromic ranges, directions of illumination, and illumination spaces. According to the medium-lighting-position multi-dimensional road lighting system disclosed by the invention, the drawback existed in the prior mainstream high-lighting-position road lighting system is overcome, and light sources and light fittings are enabled to perform own functions, so that the problems of glare, invalid lighting, poor longitudinal uniformity, and the like are effectively solved; the medium-lighting-position multi-dimensional road lighting system can adapt to the requirement of the intelligent transportation and the lighting efficiency is enhanced. The medium-lighting-position multi-dimensional road lighting system disclosed by the invention has independent application development on the basis of the characteristics of a low-power high-efficiency light source, fundamentally gets rid of the lighting system of the traditional project lamp, and steps out of the mode of simply replacing HPS (High Pressure Sodium) lamps by LED (High Pressure Sodium) lamps.

Description

technical field [0001] The present invention is the fifth part of the inventor's series of inventions - "multi-dimensional road lighting system", which relates to a new road lighting method, specifically a medium lamp position multi-dimensional road lighting method. Background technique [0002] One of the characteristics of municipal roads is that they are not completely closed, and some sections of the road are mixed with people and vehicles, and there is congestion from time to time. At present, the lighting method commonly used in municipal roads is high-light street lamps, the light source is HPS or MH, the installation height is about 10m, the installation distance is about 30m, and the single lamp power is about 250W, which constitutes the current mainstream lighting method. This lighting method is mature in technology, but due to the high lamp position and the high power of a single lamp, there are the following problems: [0003] 1. Glare problem [0004] The road...

AI Technical Summary

Problems solved by technology

[0009] In addition, the high-level street lamps under the mainstream lighting method will inevitably cause light pollution to nearby houses.

[0010] 2. Ineffective lighting problem

[0016] Therefore, there are a large proportion of ineffective lighting and violation of the basic needs of lighting in high-light lighting methods.

[0017] 3. The problem of low visibility

[0022] Uneven vertical illuminance will also lead to uneven brightness in the space ahead of the driving direction (flickering), and will also reduce the visibility RP value of the target ahead. Figure 5 shown

The unevenness of vertical illuminance, on the one hand, will lead to lower visibility in some dark areas, and also cause a decrease in overall visibility

[0023] 4. Tree occlusion problem

[0039] 2. Low level of visibility

[0040] In this low-light level lighting method, the same light source and lamp are used for the reverse and the same direction lighting components, the chromaticity is the same, and the lighting space is not independent. It is impossible to form a high brightness contrast and chromaticity contrast between the road background and the front object, and the road surface The brightness uniformity of the light is lower, resulting in a lower visibility level of objects in front

[0041] 3. This low light position lighting method concentrates all the light below the height of 1.5m on the road surface, which cannot provide the driver with the space illumination necessary to observe the obstacles ahead, and is completely unsuitable for municipal roads.

[0042] 4. This low-level lighting method cannot really eliminate glare. Within the driver's field of vision, the glare from the "light-emitting surface" of the front side lamps can still be felt (because the installation height is 1.2m)

[0043] 5. This low light level lighting method has the problem of "strobe flickering", which may easily cause driver visual fatigue
