METHOD OF EVALUATING LUMINANCE OF LIGHT SOURCE AND LIGHTING APPARATUS |
| 摘要 |
Embodiments provide a method of evaluating luminance of a light source, including acquiring first data including a plurality of luminance values by measuring luminance of the light source, converting the first data into second data corresponding to a plurality of unit cells, acquiring a moving average of the second data, and acquiring a ripple factor. The ripple factor is represented by (Draw-Ma)/Ma, where Draw is the second data and Ma is the moving average. |

1. A method of evaluating luminance of a light source, the method comprising:
acquiring first data including a plurality of luminance values by measuring luminance of the light source; converting the first data into second data corresponding to a plurality of unit cells; acquiring a moving average of the second data; and acquiring a ripple factor, wherein the ripple factor is represented by (Draw−Ma)/Ma, where Draw is the second data and Ma is the moving average. |
