FIELD: physics.
SUBSTANCE: light-emitting diode (LED) illumination device comprises two or more LED modules between which a connection element is placed. The housing of each module is provided with a link of a one-degree-of-freedom sliding pair, the second link of which is located on the connection element. To enable connection of the modules at an angle to each other, the connection element is made such that tangential planes to points on the outer surface of the connection element form a dihedral angle A, the value of which is selected based on an expression given in the description.
EFFECT: unification of the design of the housing of lamp modules, enabling modification of the illumination device during use, improved manufacturability and cheap production.
