In the modern world, effective and convenient lighting is very important. Especially in a hazardous environment where the situation changes very quickly. In particular, this applies to roads, workplaces with moving parts, in places where equipment can be contaminated with chemical or biological material by transfer. In particular, the field of medicine. Ideally, the luminaire should change its parameters with the help of control without touching. Now these lamps are used in the entertainment industry. The aim of the project is to create a controllable luminaire to illuminate the surgical table. To improve the efficiency of the luminaire, it is built on the basis of LED. To ensure a change in the illumination spot, the luminaire changes its geometry, for the intensity it is dimmed by the driver. Mossy ICEs emit an enormous amount of heat, which must be removed from the room. In this work, the calculation of the heat removal system for the luminaire is shown.
