Title:
ENVIRONMENTAL LIGHT INTENSITY DETECTOR AND CONSTANT LIGHT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/186564
Kind Code:
A1
Abstract:
An environmental light intensity detector (100, 100A) and a constant light system. The environmental light intensity detector (100, 100A) comprises a light homogenizing portion (10, 10A), a light convergence portion (20, 20A) and a sensing chip (30, 30A), wherein a light convergence light path (40, 40A) is formed on the light convergence portion (20, 20A); the light homogenizing portion (10, 10A) and a sensing face (31, 31A) of the sensing chip (30, 30A) are respectively kept on the light convergence light path (40, 40A); the light homogenizing portion (10, 10A) is configured to be subjected to light homogenizing processing when reflected light of an object passes through the light homogenizing portion so as to form light to be detected; the light convergence portion (20, 20A) is configured to be capable of converging the light to be detected to the light convergence light path (40, 40A); the sensing face (31, 31A) of the sensing chip (30, 30A) receives the light to be detected that is converged to the light convergence light path (40, 40A) by the light convergence portion (20, 20A); and the sensing chip (30, 30A) detects, by means of detecting the light to be detected, the light intensity of a usage environment.
