Lighting device used for tunnel traffic and being convenient to adjust

Abstract

The invention relates to a lighting device used for tunnel traffic and being convenient to adjust. The lighting device comprises a top plate, a processor, a lamp shell, two heat dissipating mechanismsand two hanging rods, wherein a lighting mechanism is arranged in the lamp shell, the lighting mechanism comprises a base plate, a power supply, a triggering assembly and a plurality of lighting assemblies, each lighting assembly comprises a welding plate, a triggering block, a plurality of springs, a plurality of lamp beads and two connecting units, and each heat dissipating mechanism comprisesa heat dissipating hole, a heat dissipating pipe, a filtering ring, a fan and a cleaning assembly. For the lighting device used for tunnel traffic and being convenient to adjust, through the lightingmechanism, the number of the lamp beads turned on to emit light in the lamp shell can be adjusted, thus the illuminating brightness of the device is controlled, the inside and outside brightness differences of the tunnel are weakened, then the traffic safety of the tunnel is facilitated, moreover, through the heat dissipating mechanisms, the air circulation inside and outside the lamp shade is facilitated, a filter screen is utilized for filtering dust and impurities, in addition, through the cleaning assemblies, the dredging of the filter screen can be maintained, then the heat dissipation and cooling inside the lamp shell are facilitated, the service life of the device is prolonged, and therefore, the practicability of the device is improved.

Description

technical field [0001] The invention relates to the field of intelligent lighting, in particular to an easily adjustable lighting device for tunnel traffic. Background technique [0002] LED tunnel light is a kind of tunnel light. It is suitable for flood lighting of large areas such as tunnels, smart pipe galleries, workshops, engineering construction sites, etc. It is to solve the "black hole" caused by sudden changes in vision when vehicles enter or exit the tunnel Effect" and "White Hole Effect", special luminaires for tunnel lighting. [0003] The irradiation power of the existing LED tunnel lights is constant, so the irradiation brightness also remains unchanged, but outside the tunnel, due to the influence of time, weather, light and other factors, the brightness outside the tunnel is in a changing process, while the tunnel Internally, due to the constant illumination brightness of LED lights, the brightness difference inside and outside the tunnel is also in a chang...

AI Technical Summary

Problems solved by technology

[0003] The irradiation power of the existing LED tunnel lights is constant, so the irradiation brightness also remains unchanged, but outside the tunnel, due to the influence of time, weather, light and other factors, the brightness outside the tunnel is in a changing process, while the tunnel Internally, due to the constant illumination brightness of LED lights, the brightness difference inside and outside the tunnel is also in a changing process. LED tunnel lights cannot flexibly adjust their own illumination brightness according to the external brightness conditions, resulting in the inability to eliminate or weaken the "black hole effect" and The impact of the "white hole effect" is not only that, the existing LED tunnel lights are running devices, and the lamp beads are inside the closed lamp housing, the heat generated cannot be dissipated, causing the temperature inside the lamp housing to gradually rise. Shorten the service life of LED tunnel lights and reduce the practicability of existing LED tunnel lights
