Problems solved by technology

[0002] Tunnel lights are used to provide lighting in urban tunnels. Tunnel lights usually have a fixed illuminance when lighting. In this way, when the brightness difference between the inside and outside of the tunnel is large, it is difficult for the driver's eyes to see instantly when he goes from the tunnel to the outside or enters the tunnel from the outside. Adapting to this poor brightness can easily lead to traffic accidents

Abstract

The invention discloses an adjustable-brightness tunnel lamp. The adjustable-brightness tunnel lamp comprises a lampholder and a lamp body. The lampholder is fixed to the wall near a tunnel portal, and the lamp body is arranged on the lampholder. An LED lamp is adopted for the lamp body and is connected with city power. The adjustable-brightness tunnel lamp further comprises a photoresistor connected between the LED lamp and the city power. The tunnel lamp structure can automatically adjust the illuminance of the tunnel lamp according to the difference of the brightness inside a tunnel and the brightness outside the tunnel, thus a driver can fast adapt to the change of the brightness, and the traffic accident rate is decreased.

Description

technical field [0001] The invention belongs to the field of lighting, and particularly relates to a tunnel lamp structure with adjustable brightness. Background technique [0002] Tunnel lights are used to provide lighting in urban tunnels. Tunnel lights usually have a fixed illuminance during lighting, so when the difference in brightness between inside and outside of the tunnel is large, it is difficult for the eyes of drivers to go from the tunnel to the outside or enter the tunnel from the outside. Adapt to this brightness difference, it is easy to cause traffic accidents. [0003] Chinese Patent Application No. 201020216846.6 provides a tunnel light system with adjustable brightness, including two sets of tunnel lights with adjustable brightness for lighting arranged at the entrance and exit of the tunnel, and also includes an entrance and an exit for collecting light intensity at the entrance and exit. The illuminance measurement system, the central control unit conn...
