Method and illuminometer of measuring illuminance of human body biological clock effect

Abstract

The invention relates to a method and an illuminometer of measuring illuminance of human body biological clock effect. The method and the illuminometer of measuring illuminance of the human body biological clock effect are characterized by utilizing the visual effect relevant with working and sleeping of a human body. The method and the illuminometer of measuring the illuminance of the human body biological clock effect comprise a photometry probe (1), a photoelectricity amplifying module (2), a data processing module (3), a data locking module (4) and a number-reading displayer (5). The photometry probe (1) is composed of a cosine reviser (11), a corrector (12) matched with a visual spectral response curve of the human body biological clock effect and a silicon photocell, and therefore the measuring result is enabled to be identical to the vision sensitization of the human body biological clock effect.

Description

technical field [0001] The invention relates to a method and an illuminance meter for measuring light acted by a biological clock effect of a human body, and belongs to the field of photometric radiation measurement. Background technique [0002] In addition to the two photoreceptor cells of cones and rods, there are also ganglion photoreceptor cells in the human retina. The photoreceptor of ganglion cells is related to the biological clock in the human brain, which is caused by the secretion of melatonin by the pineal gland of the brain. The biological rhythm of normal people coincides with the 24 hours of day and night alternation. With the alternation of day and night, melatonin is secreted and suppressed in large quantities, so that people work during the day and sleep at night. When melatonin in the human body reaches a certain amount, people will feel tired and drowsy. The light received by the human eye will inhibit the secretion of melatonin by the pineal gland, so...

However, it cannot measure the illuminance related to the light acting on the body's circadian clock effect

When they measure the illuminance of the action light of the visual effect of the human biological clock, there is a large deviation between the spectrum matching selected by the photometer probe and the visual spectrum of the biological clock, resulting in large errors in the measurement results, which are used to evaluate the visual illuminance of the human biological clock.
