Claims

[Scope of utility model registration request]

(1) A support body, a projector supported on the support body through a support shaft so as to be freely upward and downward, a scale plate having an angle scale, and a pointer that relatively rotates along the scale to indicate the angle of elevation. are attached to the support shaft in combination, the angle reference line formed by the scale and the pointer is maintained in a predetermined elevation direction by the action of gravity, and the elevation angle of the projector is indicated by the reading of the scale corresponding to the pointer. A lighting device characterized by comprising a scale device and the following.

(2) The pointer is rotatably attached to the support shaft with its center of gravity biased,
The scale plate is fixed to the projector so that the reading of the scale in the direction in which the pointer is directed by the action of gravity corresponds to the actual elevation angle of the projector, as claimed in claim 1 of the utility model registration. floodlight device.

(3) The scale plate is rotatably pivoted to the support shaft with its center of gravity biased, and the pointer reads the scale corresponding to the pointer when the reference scale points in a predetermined direction due to the action of gravity. The light projector according to claim 1 of the utility model registration claim, wherein the light projector is fixed to the projector so that the angle of elevation matches the actual elevation angle.

(4) The light projection device according to claim 2 or 3 of the utility model registration, wherein the pointer or the scale plate has a center of gravity biased by attaching a weight at any time.
