Problems solved by technology

In this way, the coordinates of the two monochromatic chips participating in light mixing need to be located at both ends of the standard lighting area, so that no matter how the white light is adjusted, the mixed white light is basically on the straight line connecting the two white lights, but the blackbody locus It is an arc, therefore, it is difficult for the mixed light to approximate the black body locus, so that part of the mixed light does not belong to the standard lighting light
[0008] Therefore, the above three methods of mixing light are difficult to achieve the purpose of standard lighting, and there is great difficulty in simulating daylight.

Abstract

The invention discloses a method and a device for simulating daylight changing. The device comprises a lamp with over three white light sources, and a controller, wherein one of the white light sources is positioned at one end of an illuminating area corresponding to a chromaticity diagram; another white light source is positioned at the other end of the illuminating area corresponding to the chromaticity diagram; and the other white light sources are positioned between the two ends of the illuminating area corresponding to the chromaticity diagram. The method comprises the following steps: setting a time interval, a time point, and a color temperature and a coordinate corresponding to the time point; making a comparison to obtain the color temperature and coordinate of current time; determining mixed light sources and a proportion; and controlling the light-emitting amounts of the light sources through the controller. Through adoption of the method and the device, a daylight simulation method can be simplified, and daylight can be simulated accurately.

Description

technical field [0001] The present invention relates to a method and apparatus for simulating changes in sunlight using LED lamps. Background technique [0002] In recent years, the development of cities has brought many limitations to indoor natural lighting, and many people work at night. Therefore, artificial lighting is required for supplementary lighting and lighting. At present, the color temperature of artificial lighting fixtures is fixed, and the color temperature of sunlight varies throughout the day, that is, the color temperature of morning and evening is low, and the color temperature of noon is high. It is this natural change process that maintains the normal physiological rhythm of the human body. . [0003] Based on the fact that it is difficult for lighting fixtures to imitate sunlight, in order to improve the health index of people's lives, some people have been studying how to use lamps to simulate sunlight. For example, in the patent document with the a...
