Description

Technical Field

[0001] The utility model relates to the technical field of lamp lighting, in particular to a tunnel lamp. Background Art

[0002] Since there is usually insufficient light in the tunnel, tunnel lights need to be installed on the top of the tunnel for lighting. Tunnel lights can prevent vehicles from encountering the "black hole effect" or "white hole effect" caused by sudden changes in brightness during driving. In addition to tunnels, tunnel lights are also commonly used in workshops, large warehouses, gas stations, stadiums, metallurgy and various factory areas, engineering construction and other places.

[0003] Existing tunnel lights on the market generally have a reflective film (also known as reflective paper or reflective film) installed in the lamp housing. The reflective film is located between the lamp bead and the light outlet of the lamp housing to reflect the light of the tunnel light and form a light source convergence, thereby improving the lighting brightness.

[0004] For example, a Chinese invention patent application, with application publication number CN111059505A, discloses a ceiling tunnel lamp with uniform light spot and a structure-based assembly method, which at least includes a lamp body, a light source board, reflective paper, a diffusion plate, glass and a die-cast end cap. The light source board is fixed inside the lamp body, and reflective paper and a diffusion plate are also inserted inside the lamp body. Glass is fixed on the top of the lamp body, and die-cast end caps are fixed at both ends of the lamp body. The reflective paper and the diffusion plate are arranged in a triangular position corresponding to the light source board, which effectively realizes the light source of the lamp reflecting light. On the basis of retaining the lighting function of the traditional ceiling tunnel lamp, reflective paper and a diffusion plate are added inside the lamp body in a different way, so that the lighting spot of the present invention is uniform, thereby enhancing the use effect of the present invention. The slot structure setting of the lamp body can realize the simple assembly of the whole. The overall assembly and installation are simple, convenient and practical.

[0005] For another example, a Chinese utility model patent, with authorization announcement number CN213983314U, discloses a new type of LED tunnel light, including glass, end covers, reflective paper, a lamp body radiator, an LED light source module, a driving power supply and a lamp bracket. The end cover is fixed to the end of the lamp body radiator in the long axis direction. The lamp body radiator includes a bottom wall and two inclined side walls extending from two opposite long sides of the bottom wall. The glass is fixed to the open end of the lamp body radiator, the reflective paper is fixed to the inner surface of the side wall, the LED light source module is fixed to the inner surface of the bottom wall, the lamp bracket is fixed to the end cover, and the driving power supply is fixed to the lamp bracket. The structure is simple, the installation is convenient, and the subsequent maintenance is quick; both the illumination angle and the height in the vertical direction can be adjusted.

[0006] The above two existing technical solutions specifically adopt the method of laying (laying in an eight-shaped pattern) reflective film on both sides of the interior of the lamp housing, which only considers the reflection problem of the light beam after emission in the two sides of the interior of the lamp housing, but ignores the reflection problem of the light beam after emission on the side where the light source is located, so that the convergence effect of the light after reflection does not reach the expected value, and the lighting brightness needs to be improved.
