Cleaning type lighting device with heat dissipation function for tunnel

Abstract

The invention relates to a cleaning type lighting device with a heat dissipation function for a tunnel. The cleaning type lighting device with the heat dissipation function for the tunnel comprises atop plate, an LED lamp and a protective shell, and also comprises a cleaning mechanism and a heat dissipation mechanism. The cleaning mechanism comprises a rotating assembly and two cleaning assemblies. The rotating assembly comprises a ring and a plurality of driving units. The cleaning assembly comprises a support plate, a moving unit and a cleaning unit. The cleaning unit comprises a first motor and a cleaning plate, and the heat dissipation mechanism comprises an air extraction assembly, an air injection assembly, a temperature reduction chamber and an air inlet pipe; the air injection assembly comprises a fixing shaft, a cylinder, a connecting rod and a nozzle; and according to the cleaning type lighting device with the heat radiation function for the tunnel, the protective shell canbe cleaned through the cleaning mechanism. The protective shell can be cleaned, the circumstance that dust covers the protective shell and the lighting effect of the LED lamp is affected is avoided, through the heat dissipation mechanism, heat of the inside of the protective shell is dissipated, and the circumstance that operation of internal electronic elements is affected due to over-high temperature of the inside is avoided.

Description

technical field [0001] The invention relates to the field of tunnels, in particular to a clean lighting device with heat dissipation function for tunnels. Background technique [0002] Tunnel lights are special lamps used for tunnel lighting to solve the "black hole effect" or "white hole effect" caused by sudden changes in brightness when vehicles enter or exit the tunnel. [0003] The protective shell of the existing tunnel lighting device has been exposed for a long time and is easily covered by dust, which affects the illumination effect of the tunnel lighting device and reduces the practicability of the tunnel lighting device. Not only that, the internal components of the existing tunnel lighting device will A large amount of heat energy is generated. If the heat is not dissipated in time, the internal temperature will be too high, which will affect the operation of internal components and reduce the safety of the tunnel lighting device.
