FIELD: electricity.
SUBSTANCE: invention refers to the sphere of electrical engineering. The device of light source is described in two versions, the first of which includes a movable platform, a body fixed on it, multiple light diodes installed on the body, multiple radiators, which are accordingly thermally connected and attached to light diodes and arranged in series with an interval between each other, a cooling mechanism, which sends a flow of cooling air into specified radiators in direction of their location, and a chamber covering radiators and the cooling mechanism. One of radiators scattering heat of a light diode generating highest amount of heat from multiple light diodes is arranged downstream in a flow of cooling air relative to the other ones from the specified multitude of radiators. The cooling mechanism comprises a fan arranged upstream, position of which is fixed relative to specified radiators, and a fan arranged downstream, which is fixed on the specified chamber.
EFFECT: reduced temperature of device heating with light diodes.
