LED lighting sources, appeared on the market in the 60s of the last century, are the most effective option and it is the fastest developing lighting technology for now. The problem of efficient heat removal from the LED becomes to be one of the basic ones. Due to high heat flux on the individual diodes surface, problems related to the light source cooling become to be one of the most. Modeling and thermal calculations are the solution to the problem of heat sink and maintenance of optimal thermal mode of operation of LEDs. One of the biggest drawbacks of LED lighting is the excessive price, so it is important to take into account the cost-effectiveness in selecting the components of the luminaire, and use the resour­ces correctly. In the conducted research the model of the LED light in the software complex has been designed and analyzed. And a real sample was made. As a rule, the corresponding photometric characteristics are determined depending on the field of application of the light device. In addition, the conditions of this coil are taken into account in the overload mode. Photometric characteristics and thermographic calculations for 75 W and 90 W have been measured. This proves the cost-effectiveness of a projected luminaire, using a power supply of Mean Well. The paper presents the results of light enginee­ring calculations and thermographic analysis of a sample LED device. Experimental and computational data have been compared and discussed.
