摘要： A linear lifting device including a lifting column, a synchronous adjusting mechanism, a first motion element and a second motion element is provided. The lifting column has a fixed end and a movable end. The synchronous adjusting mechanism, disposed on the movable end, has a first force-bearing end and a second force-bearing end, which are respectively separated from the center of the synchronous adjusting mechanism by a rotating radius and remain at a synchronous state. The first and second elements respectively connect the first and second force-bearing ends for generating a first force to push the first force-bearing end to move in a first force direction and generating a second force to push the second force-bearing end to move in a second force direction, such that the movable end can move with respect to the fixed end in a resultant force direction of the first and second force directions.

摘要： A planar surgical lamp includes a plurality of planar light source modules connected to form the planar surgical lamp. Each planar light source module includes a plurality of planar light source unit and each planar light source unit includes a light guide plate, which has a light incidence face and a light exit face; a light source, which generates light that enters the light guide plate via the light incidence face and projects out through the light exit face; a diffusion board, which is arranged at one side of the light exit face of the light guide plate; a surface panel, through which the light transmits; and a light guide sheet, which is arranged between the diffusion board and the surface panel. The disclosure divides a light source into a plurality of unit planar light sources so as to overcome the problems of the conventional surgical lamp of being bulky in size, great in weight, and subjected to constraints caused by laminar flows induced by the outer configuration of reflector.
