LIGHTING SYSTEM TO BE USED IN STEREOLITHOGRAPHY DEVICE Russian patent published in 2015 - IPC B29C67/00 

FIELD: electricity.

SUBSTANCE: invention is related to the sphere of stereolithography, and namely to the lighting system to be used in stereolithography device. Technical result is attained by the lighting system comprising a variety of light-emitting diodes (LEDs). At that each LED has the first light-emitting surface and the second surface, at that one of the above surfaces is flat. A variety of current leads are connected selectively to the respective LEDs so that each LED may be controlled on individual basis. The levelling flat surface is in the levelling contact with the above flat surface of each LED so that in the plane parallel to the levelling surface there is a two-dimensional matrix of LEDs. At that the levelling surface is equipped with a rigid lifting body. At that the lifting body surface is equipped with grooves limited by intermediate fins with current leads laid in them; LEDs are placed at the intermediate fins, which provide the levelling surface.

EFFECT: development of LED-based lighting system with potential joint use with optical system having a large numbered aperture.
