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

A method and device for simulating sunlight changes. The device includes a lamp and a controller of more than three white light sources, one of which is at one end of the lighting area corresponding to the chromaticity diagram, and the other white light source is at the corresponding lighting area of ​​the chromaticity diagram. At the other end of , other white light sources are between the two ends of the illumination area corresponding to the chromaticity diagram. The method is to set the time period, the time point and the color temperature coordinate corresponding to the time point, compare and obtain the color temperature temperature coordinate of the current time, determine the mixed light source and the ratio, and control the light output of the light source through the controller. The invention can simplify the method for simulating sunlight and accurately simulate sunlight.

Description

technical field [0001] The invention relates to a method and a device for simulating sunlight changes by utilizing 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 needed for supplementary lighting and lighting. The color temperature of artificial lighting fixtures currently used is fixed, while the color temperature of sunlight changes throughout the day, that is, the color temperature is low in the morning and evening, and high in the noon. It is this natural change process that maintains the normal circadian 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 simulate sunlight using lamps. For example, in the patent document with the publication number 103090...
