ULTRAVIOLET LIGHT MEASURING DEVICE

摘要

PURPOSE: An ultraviolet light measuring device is provided to measure an exposure dose of ultraviolet light by using a sensor having light receiving characteristics appropriate to erythema/blackening reaction characteristics of skin. CONSTITUTION: An ultraviolet light measuring device comprises an ultraviolet light sensing unit for measuring an ultraviolet-B index which serves as erythema reaction sensitivity characteristics of the incident light; an arithmetic operation unit(50) for determining a safety exposure time by performing an arithmetic operation based on the ultraviolet-B index measured by the ultraviolet light sensing unit, and the skin type index and SPF index which are input through an input unit(90); and a display unit(60) for displaying the safety exposure time determined by the arithmetic operation unit.
