Glare-free road illuminating lamp

Abstract

The invention discloses a glare-free road illuminating lamp and belongs to the technical field of road illumination. A lamp cup skeleton of the glare-free road illuminating lamp is an arc-shaped surface of which radius is R; a plurality of lines and rows of LED light sources with reflector lamp cups are arranged behind the arc-shaped surface; the LED light sources form an arc-shaped illuminator surface; the arc-shaped illuminator surface forms an illumination angle A capable of covering the road length L1 in the length direction of a lamp assembly; a transparent lamp shade in an illuminating part also is an arc-shaped surface of which the radius is R; a plurality of concave-convex prisms are arranged behind the arc-shaped surface along the length direction; the concave-convex prisms are used for refracting and transmitting the light of the arc-shaped illuminator surface in the width direction into the light with an angle B and then shooting the light to the road length L2; and when the lamp assembly is combined with a street lamp pole, an included angle D between the width surface of the lamp assembly and a vertical pole of a street lamp is 50-80 DEG. The glare-free road illuminating lamp has the main advantages of no glare, no light pollution and good color rendering property and is green and environment-friendly product with the remarkable energy conservation and emission reduction effects.

Description

technical field [0001] The invention belongs to the technical field of road lighting, and in particular relates to a glare-free road lighting lamp. Background technique [0002] At present, the light sources of street lamps used in the world are high-pressure mercury lamps, high-pressure sodium lamps and LED lamps to be promoted. These lamps will produce glare during use, which greatly reduces the actual lighting effect of street lamps. The so-called glare refers to the visual condition in which there is extreme brightness contrast in space or time due to inappropriate brightness distribution in the field of vision, which causes visual discomfort and reduces the visibility of objects. It is one of the important causes of traffic accidents caused by visual fatigue. When the driver is driving on the road at night, if there is no car on the opposite side, he can get good sensory vision no matter whether he turns on the low beam or the high beam, and can drive easily; When the...

Problems solved by technology

[0005] 2. Since the light is directed at 90° to the length of the road and the light spot is circular, the light will be directed to places that do not need lighting, resulting in light waste and light pollution, and the light utilization rate is low

[0006] 3. The light is illuminated in the form of diffused hemispherical volume. At the same time, the installation height of the lights is 6-14 meters. Whether it is a driver or a pedestrian driving a vehicle, as long as the eyes can see the lamp head of the street lamp, there will be a glare effect, which will make people feel uncomfortable. Closing part of the rod cell nerves will impair people's visual recognition ability at night. Under such lighting conditions, people's ability to visually reflect and judge objects on the road will be reduced, and people's walking and driving safety will also be reduced.
