The improvement of the technical equipment of television studios provides for the creation of such technological lighting systems that would improve the quality of the transmitted image. This work is carried out in two directions: 1) the efficiency of using the light emitted by widely used halogen incandescent lamps (GLN) using various optical systems is increased; 2) new powerful sources with high luminous efficiency - metal halide (MHL) - are being developed and introduced.
Technological lighting systems used in television studios are sources of optical (electromagnetic) radiation with wavelengths located in the visible spectrum, which creates the necessary illumination, as well as in the infrared (IR) and ultraviolet (UV) spectra. These types of electromagnetic energy in the optical range, depending on the intensity and duration of action, can cause various biological effects. In combination with other factors, optical radiation can have a very significant effect on the health of television studio personnel.
The labor process with a pronounced neuro-emotional load in conditions of intense lighting affects the mental performance of the speakers, which is expressed in a change in the duration of their performance of tasks of the same content before and after the TV show.
Thus, the studies carried out by us at a number of television studios in the country have shown that television workers and studio staff (announcers, illuminators, director's assistants) work under conditions of intense optical radiation, in the spectrum of which, in addition to the visible, IR- (when using GLN types KG, KGM) and UV spectral regions (when using MHL types DRI and DRISH). Radiation acts against the background of optimum air temperatures. The work of the announcers is characterized by significant neuro-emotional stress. The listed complex of factors significantly affects the functions of the body of television workers and studio staff. Consideration of the energy characteristics of the visible and infrared portion of the radiation spectrum used in television studios is of great importance for determining the thermal state of this professional contingent.
