Dynamic lighting method

Abstract

The present invention relates to a dynamic lighting method. At least one electrical parameter changing time period is set in a lighting period. The method comprises the following steps that: step 1, in each electrical parameter changing time period, a power source portion output initial electrical parameter and a power source portion output termination electrical parameter are provided, power source portion output electrical parameters change according to the same trend from the initial electrical parameter to the termination electrical parameter, wherein the initial electrical parameter is equal to an electrical parameter in a non-electrical parameter changing time period before the electrical parameter changing time period, and the termination electrical parameter is equal to an electrical parameter in a non-electrical parameter changing time period after the electrical parameter changing time period; and step 2, dynamic lighting portions are made to change lighting parameters in the electrical parameter changing time period according to the step 1, and the change of the lighting parameters makes the eye structure of a user change dynamically. The dynamic lighting method of thepresent invention actively trains the physiological structure of the eyes of the user without affecting the eye use habit, sitting posture and working pace of the user, thereby effectively maintaining the eyesight of the user.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a dynamic lighting method, which is especially suitable for occasions where vision care and / or vision training are desired, such as reading and writing work environments and home lighting environments. Background technique [0002] Visual health has also become an important issue of common concern. According to the research of "National Health Vision Report" by Peking University China Health Development Research Center in June 2015, among the total population over 5 years old in my country in 2012, most of myopia and hyperopia patients are students and office workers. The number of patients with myopia and hyperopia is about 500 million, of which the total number of patients with myopia is about 450 million. Students are under a lot of study pressure and have a lot of homework. They have to read and do homework under the light for a long time at night, and eye hygiene is very ...

Problems solved by technology

However, these methods only cultivate users from external eye habits, and cannot restore and improve vision.

If the user cannot change the reading and working habits according to the original intention of the design, for example, he must intermittently check other positions or images, or read and write postures in the middle of the reading and writing process, it will probably not be achieved due to interference with the normal use habits of the user. The expected effect of curbing vision further and further, cannot effectively protect the user's vision

[0005] Therefore, the problems in the prior art include: in a long-time reading and writing operation environment or in an environment with unscientific lighting parameters, the user's eyes cannot recover, and the ciliary muscle, pupil and / or lens are in a tense state for a long time, which Structures such as shape and size are fixed, even causing the lens and pupil to be compressed many times over a long period of time
