Collaborative dynamic lighting method and dimmable direct-current incandescent lamp thereof

Abstract

The invention provides a collaborative dynamic lighting method and a dimmable direct-current incandescent lamp thereof, relates to the field of vision and lighting, and aims to ensure that light is uniform and dynamic in a visual field. The color temperature can strictly imitate candlelight. The core is the direct-current dimming incandescent lamp technology. However, according to existing night desktop lighting, light in the visual field is mostly uneven and static, and the light quality is permanently lower than that of a direct-current incandescent lamp. Therefore, the eyes are easy to adjust and slack, and axial myopia is induced. The direct-current incandescent lamp table lamp is mainly composed of two direct-current incandescent lamp table lamp bodies, one table lamp irradiates books, and the other one irradiates the white wall in front of eyes, the light intensity of the table lamps can be adjusted to guarantee the uniformity of light in the visual field, and optic vertebral cells located in the foveal center of the retina and optic rod cells around the foveal center are stimulated at the same time. Synchronous adjustment of illuminance of the two lamps can be realized according to a program, so that eyes are guided to dynamically focus, and dynamic illumination is realized. The dynamic state is also shown in low-color-temperature lactation lighting imitating candlelightaccording to a biological clock and senile dementia prevention lighting with 40Hz depth stroboflash.

Description

technical field [0001] The invention relates to the field of vision and light health lighting, in particular to a collaborative dynamic lighting method and a dimmable DC incandescent lamp. Background technique [0002] Dynamic lighting usually refers to automatically changing the color temperature of lamps and lanterns according to the biological clock of the human body. In this application, although this meaning is also included, it more refers to the automatic change of reading and writing illuminance, causing the eyes to refocus accurately, thereby forcing the eyes to exit the state of slack adjustment, and achieve the purpose of inhibiting the abnormal growth of the eye axis. [0003] The cone cells located in the fovea of ​​the human eye are responsible for precise imaging and color resolution; the rod cells located around the retina can only image the visual field in black and white. Although the resolution is low, they are very sensitive to dynamic scenes. In additio...

Problems solved by technology

But doing so usually brings two other problems: one is that the illuminance exceeds the standard, and its harm has been mentioned in the previous paragraph. Excessive illuminance is easy to indulge the growth of the eye axis and cause myopia; the other is that the light quality and light health of ordinary desk lamps They are better than ceiling lamps, that is, the light of ceiling lamps will pollute the light of table lamps, resulting in unnecessary blue light hazards

Although the existing AC incandescent lamp dimming technology is cheap, it will introduce strobe, and it is difficult to realize the simultaneous and precise control of the two light sources, and it is also impossible to make the incandescent lamp work at over-rated power for a short time

[0013] In short, the existing lighting technology and standards not only generally reverse the direction of reading and writing illuminance, but also generally lack in the spectrum, and are generally unaware of the non-visual effects of light that light will ripen children; there is an urgent need for a synergistic Dynamic lighting method and its dimmable DC incandescent lamp to solve many of the above problems
