Safety lighting lamp box device used in tunnel

Abstract

The invention discloses a safety lighting lamp box device used in a tunnel, and belongs to the technical field of tunnel lighting. The safety lighting lamp box device comprises a lamp holder, a tunnel lamp panel is fixed to the middle of an inner cavity of the lamp holder, at least four sets of rotating rollers are movably connected to the wall of the inner cavity of the lamp holder, and the outer sides of the rotating rollers are sleeved with light-transmitting films; the light-transmitting films are located on the outer side of the tunnel lamp panel, one set of rotating rollers are fixedly connected with a servo motor, the servo motor is fixed to the inner side wall of the lamp holder, one side of the bottom of the lamp holder is fixedly connected with a transverse connecting plate, and the upper surface of the transverse connecting plate is movably connected with a scraping plate through a spring. The upper surface of the scraping plate contacts with the outer side surface of the light-transmitting film. According to the invention, the tunnel lamp panel is wrapped with the light-transmitting film, the outer side surface of the light-transmitting film is cleaned in a rotary scraping mode, it can be conveniently guaranteed that the outer surface of the light-transmitting film is clean, and therefore the illumination light intensity is conveniently improved, and convenience is brought to tunnel illumination.

Description

technical field [0001] The invention relates to the technical field of tunnel lighting, in particular to a safety lighting light box device used in tunnels. Background technique [0002] The light box (Sharkarstain) is a viewing light box (illuminator) for X-ray pictures (negative films). Light boxes generally use light sheets, preferably PC boards. This material can withstand high temperatures up to 145 degrees and low temperatures up to -55 degrees. According to the material, there are ultra-thin light boxes, blister light boxes, rolling light boxes, crystal light boxes, cloth light boxes, electronic light boxes, EL light boxes, LED light boxes, acrylic light boxes, aluminum light boxes, glass fiber reinforced plastic light boxes, stainless steel light boxes, etc. Tunnels can facilitate the rapid progress of transportation, etc., but when transportation is carried out in the tunnel, because the tunnel is relatively dark, light boxes will be installed in the tunnel along t...

Problems solved by technology

[0007] In order to solve the problem that the current lighting devices used in tunnels often use lighting fixtures placed on the top of the tunnel. The lamps used in the tunnel are easy to be contaminated with dust, and the height of the top of the tunnel is not convenient for manual cleaning, which often results in a large amount of dust covering the lighting fixtures. , leading to poor light transmission of the lamp housing, which in turn affects the normal lighting work of the lamps in the tunnel and the lighting light boxes in the tunnel. When the lamps are used, the light color is usually relatively single, and it is not convenient to adjust the lighting color of the lighting light according to the needs of the light color. Problem, the purpose of this invention is to provide a kind of safety lighting light box device used in the tunnel
