Low-position light-emitting diode (LED) lighting device of tunnel

Abstract

The invention discloses a low-position light-emitting diode (LED) lighting device of a tunnel. The device comprises a lamp body sectional material, a glass plate, a light-diffusion type light transmission plate, two end covers, a male plug, a female plug and two buckling covers, wherein the glass plate and the light-diffusion type light transmission plate are positioned in the lamp body sectional material; the two end covers are packaged on two sides of the lamp body sectional material; the male plug and the female plug are connected with the two end covers respectively; the two buckling covers are positioned on the outermost side and connected with two ends of the lamp body sectional material respectively; an LED chip, a reflecting plate, a diffusion plate and a lamp bar plate are arranged in one buckling cover; the lamp bar plate is a printed circuit board (PCB) and arranged on the side part of the LED chip; and the diffusion plate is arranged on the other side, opposite to the lamp bar plate, in the buckling cover. The LED chip is modularized to facilitate adjustment of brightness and an irradiation distance; and the glass plate and the light-diffusion type light transmission plate realize secondary light-changing performance and make a light source diffused. The low-position LED lighting device of the tunnel has the advantages that: the structure is smart; light emitting brightness is high by using the technologies of light emitting of an LED chip module and secondary light changing; glare is avoided; and visual comfortability is improved.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a tunnel low-position LED lighting device. Background technique [0002] In the existing tunnel lighting, using the lighting method of overhead light source, installation, use, maintenance, high cost and high risk, the above work can only be carried out after the traffic is interrupted. Tunnel lighting is a worldwide problem, especially in underground tunnels , the installation and maintenance are more difficult and dangerous. The lamps and lanterns work in the harsh environment of humidity, vibration and wind pressure, and the damage rate is relatively high. It will be more troublesome to replace or repair each time. The reflector will be irradiated by side direct light, which will make the driver's vision very uncomfortable and easily cause traffic accidents. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the present inventio...

[0002] In the existing tunnel lighting, using the lighting method of overhead light source, installation, use, maintenance, high cost and high risk, the above work can only be carried out after the traffic is interrupted. Tunnel lighting is a worldwide problem, especially in underground tunnels , the installation and maintenance are more difficult and dangerous. The lamps and lanterns work in the harsh environment of humidity, vibration and wind pressure, and the damage rate is relatively high. It will be more troublesome to replace or repair each time. The reflector will be irradiated by direct light from the side, and the driver's vision will be very uncomfortable, which will easily cause traffic accidents
