[0004] (2) Affect mood: long-term lack of melatonin will lead to mood disorders and other phenomena;
[0009] It is worth noting that although the device for measuring the degree of melatonin suppression disclosed in U.S. Patent No. US 8,812,242 can quantify the degree of melatonin suppression caused by short-wavelength (<460nm) color light in the human body, its accuracy is not Being questioned
The main reason is that the action spectrum (Action spectrum for melatonin suppression) created by the internal processor of the device based on the actually received short-wavelength (<460nm) colored light may not be able to accurately describe the effects of short-wavelength colored light on human melatonin suppression. degree of inhibition

Abstract

The present invention provides a device for quantifying the degree of inhibition of melatonin secretion by a light source, comprising: a light receiving unit, a preprocessor, a main processor, and a display unit. Particularly, the main processor has a first action spectrum generation unit, a second action spectrum generation unit, and a spectrum integration unit; wherein, the first action spectrum generation unit is used for wavelengths greater than 460 nm included in the spectral data The data is converted into a first action spectrum, and the second action spectrum generating unit is used for converting data with a wavelength shorter than 460 nm included in the spectral data into a second action spectrum; and the spectrum integration unit is used for the first action spectrum. An action spectrum is integrated with the second action spectrum into a total action spectrum. At the same time, experimental data show that the device for quantifying the degree of inhibition of melatonin secretion by a light source proposed in the present invention can improve the accuracy of the existing measuring device in quantifying the degree of melatonin inhibition caused by short wavelength (<460nm) color light. .

Description

technical field [0001] The present invention relates to the related technical field of physiological quantification devices, in particular to a quantification device for the degree of inhibition of melatonin secretion by a light source. Background technique [0002] Melatonin is secreted by a gland in the human brain called the pineal body. Its effects on human physiological functions can be classified into the following categories: [0003] (1) Promote sleep: Melatonin has a hypnotic effect and helps sleep; [0004] (2) Affecting mood: Long-term lack of melatonin will lead to mood disorders and other phenomena; [0005] (3) Sexual maturation and reproduction: Melatonin can affect the secretion of gonadotropin by the hypothalamus, and at the same time, it can also affect the effect of gonadotropin on the pituitary gland; and [0006] (4) Effects on immune function: Melatonin can induce T lymphocytes to synthesize and release interleukin-2 (interlukin-2, IL-2) and interleuk...
