Title:
METHOD AND SENSOR FOR DETECTING AMBIENT ILLUMINATION IN LAMP
Document Type and Number:
WIPO Patent Application WO/2018/064834
Kind Code:
A1
Abstract:
A method and sensor for detecting the ambient illumination in a lamp, comprising the following steps: acquiring a visible light waveband ambient illumination value by means of a visible light detection module (14) and acquiring a non-visible light waveband ambient illumination value by means of a non-visible light detection module (15); when the ambient illumination value of the visible light is less than a preset illumination value, switching on the lamp; acquiring a lamp light and natural light visible light waveband mixed illumination value and a lamp light and natural light non-visible light waveband mixed illumination value; and, on the basis of the ambient illumination values and the mixed illumination values, calculating a shutdown threshold for switching off the lamp. The sensor comprises the visible light detection module (14), the non-visible light detection module (15), a sensing and detection module (12), a functional interface settings module (13), an MCU program control module (16), and a drive circuit control module (17). Accurate detection of natural light spectrum illumination is implemented without interference from the synthetic light spectrum illumination of the lamp, enabling accurate and stable control of the lamp.
