Problems solved by technology

[0003] Traditional tunnel lights are in the form of direct lighting, and the illuminants are point-shaped or linear strong light sources, which are prone to glare
Limited by space, the installation position of tunnel lights is generally low, mostly below 6 meters, and the lights can easily enter the driver's eyes, so the glare problem is more serious and endangers driving safety
In order to reduce glare, some lamps also use frosted lampshades to make the light soft, but this will inevitably lead to a significant drop in light efficiency, resulting in a waste of energy

Embodiment Construction

[0025] refer to figure 1 , Figure 5 ,in figure 1 It is a schematic diagram of the structure after installation. Figure 5 It is an exploded view, the tunnel lamp of this embodiment includes a lamp body 1 , an LED assembly 4 , a panel 5 and a reflector 10 .

[0026] The lamp body 1 is also used as a heat sink, and is formed by a deformed aluminum alloy with good thermal conductivity through a hot extrusion process. There are a number of heat dissipation fins 1-1 on it. In order to avoid dust accumulation, the heat dissipation fins 1-1 All vertical lamp body 1 is set downward. The position direction of this embodiment is determined by referring to the normal installation position, pointing downward to the bottom of the lamp body.

[0027] The LED assembly 4 includes an aluminum substrate and a number of LED lamp beads arranged on it. In order to reduce side light leakage, polarized lenses are installed on the LED lamps at both ends of the LED assembly. Since the polarized l...

Abstract

The invention provides a diffuse reflection tunnel lamp which comprises a lamp body also serving as a radiator, an LED component, a light-transmitting panel and a reflecting cover. A plurality of radiating fins are arranged on the lamp body, the LED component is mounted on the lamp body, the light-transmitting panel is mounted on the lamp body and located above the LED component, the reflecting cover comprises a cover body and a mounting portion used for connecting the lamp body, the cover body comprises a support portion and an arc-shaped reflecting portion, one end of the support portion is connected to the mounting portion while the other end of the same is connected to the arc-shaped reflecting portion, and the inner surface of the reflecting cover is coated with a high-diffuse-reflection coating. The diffuse reflection tunnel lamp has the advantages that efficiency and energy conservation can be achieved, and glare is eliminated.

Description

technical field [0001] The invention relates to a tunnel light, in particular to a diffuse reflection tunnel light using LED as a light source, and belongs to the technical field of lighting fixtures. Background technique [0002] Tunnels are special sections of high-grade highways, and a series of visual problems will appear when vehicles drive into, pass through and leave the tunnel. In order to adapt to visual changes, tunnel lighting needs to be set up. [0003] Traditional tunnel lights are in the form of direct lighting, and the illuminants are point-shaped or linear strong light sources, which are prone to glare. Limited by space, the installation position of tunnel lights is generally lower, mostly below 6 meters, and the lights can easily enter the driver's eyes, so the glare problem is more serious and endangers driving safety. In order to reduce glare, some lamps also use frosted lampshades to make the light soft, but this will inevitably cause a sharp drop in l...
