The invention discloses a section tunnel light for rail transit, which comprises a casing, the bottom of the casing is fixedly connected with a lampshade, the top of the lampshade is embedded with an LED lamp board, and the top of the LED lamp board is provided with a heat dissipation A fan is embedded in the center of the top of the housing, and the air outlet of the fan faces the heat sink. Both sides of the housing are provided with heat dissipation holes. The number of the heat dissipation holes is several, and the heat dissipation The holes are divided into upper and lower rows. The present invention can effectively dissipate heat from the LED lamp board through the arrangement of the housing, the fan, the heat sink and the heat dissipation holes, and prolong the service life of the tunnel light. The setting of the second installation hole and the connection hole can facilitate the adjustment of the irradiation direction of the LED lamp board when the tunnel light is installed, so that the irradiation angle of the tunnel light can meet the actual needs. |
