Title:
DETECTION SYSTEM AND DETECTION METHOD FOR DETECTING LIGHT POWER OF LIGHT EMITTING MODULE
Document Type and Number:
WIPO Patent Application WO/2020/114001
Kind Code:
A1
Abstract:
A detection system (100) for detecting light power of a light emitting module (200), comprising a light transmission film (20), an image capturing device (30), and a light detection module (40). The light transmission film (20) and the image capturing device (30) are sequentially disposed at a light emission path of the light emitting module (200). When the light emitting module (200) emits light toward the light transmission film (20), the image capturing device (30) is used to capture the light transmission film (20) so as to form a captured image. The brightest region in the captured image has a correspondence with a region to undergo detection (210) of the light emitting module (200). The light detection module (40) can be aimed at said region (210) to perform detection with respect to the same, so as to obtain the maximum optical power of the light emitting module (200).
