Description

Shadowless street lamp

Technical Field

The utility model relates to a LED lighting technology specifically is a shadowless street lamp.

Background

With the rapid development of modern science and technology, street lamps have been deeply inserted into various streets or intersections of cities. However, the existing widely-used street lamps basically belong to shadowy lamps, and the phenomenon of the shadowy lamps is obvious after the street lamps are lighted at night. The shadow is formed by irradiating an object with light, and the shadow is different from place to place on the earth. Carefully observing the shadow under the light, finding that the middle part of the shadow is particularly dark, the periphery is slightly shallow, the particularly dark part in the middle part of the shadow is called a home shadow, and the gray part at the periphery is called a penumbra, the generation of the phenomena is closely related to the linear propagation of the light, an object can generate the shadow consisting of the home shadow and the penumbra under the light, the shadow consisting of the home shadow and the penumbra is a shadow effect, and the reason is that the larger the area of a luminous object is, the smaller the home shadow is. When the night screen falls, the black shadow effect among the street lamps in line is often seen on the whole road after the street lamps are lighted, and the visual attractiveness is extremely influenced. In addition, the shadow street lamp on the market at present has other defects and deficiencies to be specifically explained as follows:

(1) in the driving process at night, traffic accidents are easily caused by the blind areas of the vision of drivers caused by the shadow effect among the street lamps.

(2) In the process of monitoring and extracting vehicles by road monitoring, required monitoring data cannot be normally extracted due to monitoring blind areas caused by the shadow effect among street lamps.

(3) Pedestrians walk on the road at night, and visual errors are easily caused by the shadow effect between the street lamps, so that accidental injuries are caused.

(4) When the street lamps are used for searching for objects at night, lost objects cannot be accurately found due to vision blind areas caused by the shadow effect among the street lamps.

Therefore, in summary, the shadow street lamps in the market at present cause inconvenience to people in daily life. Therefore, a shadowless street lamp needs to be developed to overcome the defects and shortcomings.
