Lighting method and lighting device

Abstract

The embodiments of the invention disclose a lighting method and a lighting device. The method is used for adjusting the illumination of light emitted by a lighting source in an irradiation target area, the target area is irradiated by an environmental light source, and the lighting method comprises: acquiring light illumination of an auxiliary area not in the irradiation of the lighting source, under the irradiation of the environmental light source; determining the light illumination of the target area only under the irradiation of the environmental light source as environmental illumination according to the light illumination of the auxiliary area under the irradiation of the environmental light source; judging whether the environmental illumination is changed and the change quantity exceeds a preset environmental change range; if so, adjusting the current supplied to the lighting source, so that the light illumination of the target area is located within a target illumination range. By adopting the method and the device, when the lighting environment of the target area is changed greatly, the light illumination of the target area can still be maintained within a target illumination range, so that a good lighting environment is provided for users, and eye health is effectively protected.

Description

technical field [0001] The invention relates to the technical field of illumination, in particular to an illumination method and an illumination device. Background technique [0002] With the rapid development of lighting technology, lighting has long been no longer limited to making the illuminated objects in the target area illuminated, but has been upgraded to a way to simultaneously achieve Technology that illuminates objects and protects the human eye, this lighting technology is used more and more today. [0003] In the prior art, the following steps are generally taken to make the illuminance of light in the target area meet the requirements of eye protection: [0004] Fix the lighting device at one position, and calculate the straight-line distance between the lighting source in the lighting device and the target area at this time; [0005] Calculate the current value supplied to the lighting source in the lighting device according to the ideal light illuminance of...

AI Technical Summary

Problems solved by technology

[0007] However, there may still be technical defects in this type of existing lighting technology, for example: when the target area is affected by the illumination light of other lighting devices, the illuminance of light in the target area will change, which does not meet the needs of eye protection

At this time, when people work or study in the target area, it will seriously affect people's eye health
