LED DEVICE FOR DRAWING WITH LIGHT IN AIR (OPTIONS) Russian patent published in 2021 - IPC A63B43/00 A63B43/02 A63B43/06 A63B67/08 

FIELD: lighting.

SUBSTANCE: group of inventions relates to LED device for drawing with light in the air. LED device for drawing with light in the air contains a case in the form of a ball of hollow spherical thin-wall shell made of transparent plastic connected to a cord, having at the other end a handle pivotally connected to a cord or a loop for user’s hand, which is pivotally connected to a ball, as well as LEDs, a processor board and a power source connected to the processor located inside the shell. The ball shell is made of transparent polyurethane. A tubular channel for placing the power source is formed inside the shell cavity along its diameter. The first recess for placing a rolling bearing, to which the cord end is attached, is made from one side of the shell in zones of connection of the channel to the shell. On the inner wall of the shell, along the tubular channel, thin-wall tubular channels are formed connected to the shell with jumpers or partitions for placing LED line inside each of them. Between these channels, on the inner wall of the shell, along the tubular channel, other thin-wall tubular channels are formed for placing weighting devices inside them. The second recess is made from the other side of the shell with holes in the sidewall of this recess, which are placed opposite to the specified channels for LED lines and weighting devices. Inside the second recess covered with a lid, the processor board is located. All the channels and means of their connection to the shell surface, as well as lids for recesses, are made of the same material – transparent polyurethane.

EFFECT: increased operational strength of the ball-shaped case and shape restoration when placing LED lines on the wall surface of the ball sphere.
