Example Embodiment

[0022] The technical solutions of the present invention will be described in detail below in conjunction with embodiments.

[0023] The invention provides a tunnel lamp, comprising a lamp holder and a lamp body, wherein the lamp holder is fixed on the wall close to the tunnel entrance, and the lamp body is arranged on the lamp holder, and the surface of the lamp holder is also provided with a heat dissipation device. The heat dissipation of the lamp body during operation prevents the lamp body from shortening its service life due to excessively high working temperature; in this embodiment, heat dissipation can be achieved by pasting a number of heat sinks on the surface of the lamp holder.

[0024] The lamp body can obtain a working power source by connecting with the city power supply, and provide stable and continuous lighting. In this embodiment, in order to save energy, the present invention adopts dual power supply. In addition to connecting the lamp body to the mains, it is a...

Abstract

The invention discloses a tunnel lamp. The tunnel lamp comprises a lamp holder and a lamp body, wherein the lamp holder is fixed on a wall near to a tunnel entrance, the lamp body is arranged on the lamp holder and is connected with a mains supply, the tunnel lamp also comprises an illuminance transducer and a master controller, the lamp body adopts n groups of LED lamps with different colors, n is more than or equal to 2, the illuminance transducer is arranged at the tunnel entrance and is used for sensing illuminance data outside a tunnel and sending the illuminance data to the master controller, the master controller is used for adjusting a brightness value of each group of LED lamps according to the illuminance data, so that required illuminance is obtained after all LED lamps are mixed. By the tunnel lamp structure, the illuminance of the tunnel lamp can be automatically adjusted according to light brightness outside the tunnel, so that a driver can quickly adapt to brightness change during going through the tunnel, and the occurrence rate of a traffic accident is reduced.

Description

technical field [0001] The invention belongs to the field of lighting, in particular to a structure of a tunnel lamp whose brightness can be adjusted. Background technique [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. [0003] Chinese patent application number 201020216846.6 provides a tunnel light system with adjustable brightness, including two sets of tunnel lights with adjustable brightness for lighting at the entrance and exit of the tunnel, and also includes entrance and exit for collecting light intensity at the entrance and exit The illuminance measurement system, the central con...
