Abstract

PURPOSE:To perform the condensing operation of a multi-lamp type lighting for operation on both sides of the lighting by revolving the light source lamps connected to a rotary plate by connection levers when the revolving power due to a revolving power applying part is transmitted to the rotary plate to tilt them in a condensing direction. CONSTITUTION:For example, when one condensing knob 8a is revolved, a shaft 9a is rotated around its axis and, by this rotation, the rotary plate 12 engaged by an engaging piece 13a with the leading end part of the lever 22a fixed to the shaft 9a is revolved centering around a support shaft 12a. Light source lamps 14-17 are attached to respective attaching frames 14c-17c in a freely revolvable manner by revolving shafts 14d-17d and the revolving shafts 14d-17d are positioned on a concentric circle centering around the shaft 12a of the revolving plate 12. Therefore, the light source lamps 14-17 are revolved by the revolving shafts 14d-17d and together tilted in a condensing direction. Since the respective light source lamps 14-17 are connected to the rotary plate 12 by connection links 18-21, they are together tilted in the condensing direction by the revolution of the rotary plate 12.

3a and 13b are provided. Therefore, for example, when one of the condensing knobs 8a is rotated, the shaft 9a rotates about its axis, but the tip of the lever 22a fixed to the shaft 9 is rotated by the rotating plate 12. Since the locking piece 13a is locked, the rotation plate 12 rotates about the support shaft 12a by the rotation of the shaft 9a.

Further, centering on the arrangement position of the base portion 11, four light source lamps 14, 15,
Although 16 and 17 are provided, the number of lights is not limited to four. Each of these light source lamps 14, 15, 16, 17 is shown in FIG.

Rotate counterclockwise. By this rotation, the tip of the lever 22a fixed to the shaft 9a rotates counterclockwise with the locking piece 13a of the rotating plate 12 locked, so that the rotating plate 12 Is the spindle 12a
It rotates clockwise about the rotation center as shown by the solid line.

When the rotating plate 12 is rotated clockwise, the connecting links 18, 19, 20, 21 are connected to the light source lamps 14, 1 respectively.
Since the upper parts of 5, 16, 17 are pressed toward the outer peripheral direction, the light source lamps 14, 15, 16, 17 are rotated by their respective rotation shafts 14d, 15d, 16d, 17d. Due to the movement, the light source lamps 14, 15, 16 and 17 are all tilted in the direction of collecting light.
