The utility model discloses an explosion-proof type
airplane passenger cabin lighting device, which relates to the technical field of
airplane passenger cabin lighting, and comprises a fixing ring, the outer side of the fixing ring is fixedly connected with an
assembly flange, the fixing ring is arranged in a passenger cabin through the
assembly flange, and the fixing ring is flush with the inner wall of the passenger cabin; a mounting ring is in threaded connection with the interior of the fixing ring, two symmetrically-distributed clamping blocks are connected with the interior of the mounting ring in a clamped mode, the two clamping blocks are spliced to form a ball seat structure, a
ball joint is rotationally connected with the interior of the ball seat structure, and a lighting structure is mounted in the
ball joint. According to the anti-explosion type
airplane passenger cabin lighting device, the lighting
assembly is allowed to rotate freely in any direction through a ball seat structure formed by a
ball joint and a clamping block, precise angle fixing is achieved through cooperation with damping, and the
irradiation range of
LED lamp beads can be adjusted through the linkage design of a movable sleeve and a lens; the requirement for multi-dimensional adjustment of the lighting direction and range in a passenger cabin scene is met, and meanwhile safety is ensured through an anti-explosion material and a sealing structure.
