FIELD: illumination, mechanics. ^ SUBSTANCE: rotary lighting device incorporates a light-emitting module and a rotary mechanism comprising a base and a post attached to the said light-emitting module to turn around the base. The device comprises also an appliance to fix the relative position of the base and post. The base represents a support with an upper support surface and a side surface. The post is made up of two parallel arc-like rods with their end parts fastened with the light-emitting module, while the concave outer surface part interacts with the base support surface. The outer surface of every rod is furnished with crosswise ledges arranged along its length, while the inner surface has a vertical shoulder running along the bar length. The base support surface has a recess representing an arc-like bottom slot with radius of curvature corresponding to that of arc-like bars. The said slot bottom has crosswise recesses with the shale matching that of the bar outer surface ledges, and a through hole receiving a tightening screw. The fixing appliance represents a tightening screw and a box-like plug arranged in the base slot, its upper part furnished with a through hole for tightening screw and its end face parts furnished with slots for bar shoulders. The arc-like bars are arranged in the support surface slot so that their ledges interact with the slot bottom recesses, the bars being passed through the plug so that their shoulders come through the plug end face part slots, while the plug lower edges rest against the bar inner surface. A threaded sleeve abuts on the support surface rear side slot bottom through hole, said the threaded sleeve housing the tightening screw passed through the plug and base slot through holes. ^ EFFECT: inclined light-emitting module in the vertical plane. ^ 3 cl, 6 dwg |
