Light source module and lamp

Abstract

A light source module comprises a white light generating part and a red light generating part emitting red light, the white light generating part emits first white light, the red light generating partemits red light, and the maximum value of the spectral intensity of light emitted by the red light generating part is larger than the maximum value of the spectral intensity of light emitted by the white light generating part. Light emitted by the red light generating part and light emitted by the white light generating part are mixed to form second white light, and the proportion of spectral radiation energy of the light emitted by the red light generating part within the range from 600 nm to 780 nm in the total radiation energy of the second white light within a visible light interval from380 nm to 780 nm is 30.0-50.0%. According to the light source module, spectral distribution is optimized, energy of a red light area is increased, the specific energy proportion is limited to be below50%, the balance requirement of night work efficiency and rhythm stimulation of workers can be met, and the light source module is particularly suitable for being used by the workers at night.

Description

technical field [0001] The invention relates to a light source module and a lamp for lighting. Background technique [0002] According to the research report of scientists, there are the third type of human photoreceptor cells ipRGCs in the retina of the human eye. Through these cells, the external light sensed by the human eye is transmitted to the human brain nervous system, which in turn affects the secretion of cortisol, melatonin, etc. , thereby affecting people's health, happiness, alertness, sleep quality, the body's biological clock, etc. [0003] In order to improve or maintain people's concentration, alertness, and work efficiency during daytime work, lighting conditions with higher CS values ​​(higher illuminance, high color temperature, and higher spectral intensity of blue-green light) are generally used to inhibit melatonin. Secretion; when resting and relaxing at night, use lighting conditions with lower CS value (lower illumination, lower color temperature, ...

AI Technical Summary

Problems solved by technology

[0004] In real life, many people have to work at night (such as overtime workers or shift workers). It turns out that high-illuminance, high-color-temperature light used at night will affect people's rhythm, sleep quality and health; Illumination and low color temperature light are used to work at night, which will affect work efficiency
