Adaptive illuminating light and shade adjusting method, illuminating lamp and application of illuminating lamp

Abstract

The invention discloses an adaptive illuminating light and shade adjusting method, an illuminating lamp and an application of the illuminating lamp. The illuminating starting processes of the adjusting method are as follows: the light color progressively increases to 1500-2700K according to a CIE1931 spectrogram blackbody radiation track from 0s to 10-40s, progressively increases and is stabilized at a set color temperature value from 10-40s to 120-240s according to the CIE1931 spectrogram blackbody radiation track; and meanwhile, the illuminating brightness progressively increases and is stabilized at a rated value from 0s to 120-240s. The illuminating extinguishing processes are as follows: the light color progressively decreases and is stabilized at 1500-2700K according to the CIE1931 spectrogram blackbody radiation track from 0s to 10-40s; and meanwhile, the illuminating brightness progressively decreases to zero from 0s to 180-360s. An adaptive light and shade illuminating lamp is the lamp employing the adjusting method. Through synchronous integrated control of the brightness and the spectrum, the adverse effects such as stimulation which is suddenly caused at the illuminating light and shade moments can be reduced to the maximal extent; the adaptive light and shade illuminating lamp plays a comfortable protection role in human eyes and is applied to illuminating products for mothers and infants; and normal development of vision systems of the eyes of the infants can be effectively protected.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a lighting self-adaptive light and shade adjustment method, a lighting fixture and an application thereof. Background technique [0002] When the visual environment conditions change, a series of adaptive processes will be produced inside the human eye to match the best visual experience in the environment. The process of light adaptation from dark environment to light environment is relatively fast, and it goes through the process from initial adaptation to complete adaptation. The mechanism is that the rod cells accumulate a large amount of rhodopsin in the dark environment, and when they enter the bright environment, they quickly decompose when encountering strong light, thus producing dazzling light perception. Only after more rhodopsin is rapidly decomposed can the cone pigments, which are less sensitive to light, be able to sense light in a bright environment and restore...

Problems solved by technology

[0003] Newborn babies have a complete eye tissue structure, but the visual system is not fully developed. 0-3 years old is the critical period for the development of the baby's eye visual system. The light that changes in light and dark brings visual adaptation stimulation, visible light with high radiation intensity, and flickering will all affect the baby's vision.
