Interval tunnel light for rail transit

Abstract

The invention discloses a section tunnel lamp for rail transit, comprising a casing. Said casing bottom is fixedly connected with a lampshade, an LED lamp panel is embedded in the top of the lampshade, and a heat dissipation is arranged on a top of the LED lamp panel. A fan is embedded in the center of the top of the casing, and the air outlet of the fan faces the heat sink. The two sides of the casing are provided with heat dissipation holes. The number of the heat dissipation holes is several, and the heat dissipation is performed. The holes are divided into two rows. The invention can effectively dissipate heat of the LED lamp board through the arrangement of the casing, the fan, the heat sink and the heat dissipation hole, prolonging the service life of the tunnel lamp. The invention includes the semicircular adjustment seat, the fixing plate, the adjustment hole, the first installation hole, the second installation hole and the connecting hole, which can facilitate the adjustmentof the illumination direction of the LED light board when the tunnel light is installed, so that the illumination angle of the tunnel light meets the actual needs.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an interval tunnel light for rail transit. Background technique [0002] With the laying of my country's three-horizontal and six-vertical railway lines and the rapid development of high-speed railways, when laying railways in rugged mountains, tunnels are usually opened to shorten the distance, and tunnel lights are often used in the tunnels. Maintenance personnel maintain the tunnel. Traditional tunnel lights will generate a lot of heat when used for a long time, which will accelerate the aging of tunnel lights and reduce their service life. However, the traditional tunnel lights have poor heat dissipation effect. In addition, it is inconvenient to install tunnel lights It is inconvenient to adjust the angle. Contents of the invention [0003] The purpose of the present invention is to provide a section tunnel light for rail transit, which has the advantages of adjustable...
