ULTRAVIOLET BACTERICIDE UNIT Russian patent published in 2015 - IPC A61L9/20 

FIELD: medicine.

SUBSTANCE: ultraviolet bactericide unit comprises an ultraviolet lamp, an operational life analyser, a start-control device, ambient temperature and/or humidity and/or supply voltage and/or lamp life analyser unit connected to a control unit setting effective exposure time by formula t_e=k_e×t_exp, wherein t_e is the effective exposure time, t_exp is the exposure time, and k_e=k_u×k_T×k_φ×k_t, wherein k_T is a coefficient of ambient temperature variations, k_φ is a coefficient of ambient humidity variations, k_u is a coefficient of supply voltage fluctuations, k_t is a coefficient of estimated exposure time.

EFFECT: invention provides automatic exposure time management.
