Annotation: The article describes the installation of an improved reflect meter, complete with six infrared LED lights. As a result of theoretical research developed experimental setup for physical modeling of thermal stress in the workplace with an intense heat. Based on the physical modeling of the regularities of changes thermoradiation intensity depending on the spatial arrangement of heat sources.

Key words: heat flow, sensor, excessive heat radiation, heating temperature, measurement range.

A fluidizer light design, consisting of light chamber, is resulted in the article; semilucent screen; matrices of ultra of bright light-emitting diodes. As a result of theoretical researches an experimental fluidizer is developed physical design of thermal tension on workplaces with intensive teplovydeleniem. On the basis of physical design conformities to law of change thermo of radiation tension are set depending on the spatial location of sources of caloradiance.

Keywords: heat flow, sensor, excessive heat radiation, heating temperature, measurement range.
