BACKGROUND OF THE INVENTION
1. Technical Field
The invention relates to the technical field of infrared sensing, in particular to an integrated infrared sensing device for controlling a light source and a using method thereof.
2. Description of Related Art
The majority of current streetlights use light sensors for on/off control of a light source. These streetlights automatically turn on in the dark, consistently emitting light regardless of whether there are people around or not, leading to a waste of electricity.
In order to conserve electricity, an existing sensor streetlight is equipped with an infrared sensor on a light pole. The infrared sensor controls the on/off of the light source by detecting the presence of human beings or moving objects. The infrared sensor on the light pole has a sensing capability within a specific area or angle and can detect one or multiple persons within the sensing range, allowing for regulation of the lighting of the streetlight. An example of such a technology can be found in the US patent with the publication number US20190215935A1.
However, the patent has the following problems: first, there is only one infrared human body sensing probe on the streetlight, allowing sensing within a limited angle and incapable of achieving 360-degree coverage; second, the sensing distance of the infrared sensing probe on the light pole is fixed and non-adjustable, so the streetlight with this structure cannot adequately serve the needs of users; and third, the brightness of the light source on the existing streetlight is generally fixed, lacking the capability to be adjusted according to user preferences.
Based on the above problems, it is necessary to provide a novel infrared sensing device, which enables 360-degree sensing of humans or objects, and allows adjustable sensing distance of an infrared sensing probe as well as brightness control of a light source, effectively meeting the diverse requirements of users.
