Detailed Description

Various embodiments of the present disclosure will be described more fully hereinafter. The present disclosure is capable of various embodiments and of modifications and variations therein. However, it should be understood that: there is no intention to limit the scope of the disclosure to the specific embodiments disclosed herein, but rather, the disclosure is to cover all modifications, equivalents, and/or alternatives falling within the spirit and scope of the various embodiments of the disclosure.

Hereinafter, the term "includes" or "may include" used in various embodiments of the present disclosure indicates the presence of the disclosed functions, operations, or elements, and does not limit the addition of one or more functions, operations, or elements. Furthermore, as used in various embodiments of the present disclosure, the terms "comprising," "having," and their derivatives, are intended to be only representative of the particular features, integers, steps, operations, elements, components, or combinations of the foregoing, and should not be construed as first excluding the existence of, or adding to one or more other features, integers, steps, operations, elements, components, or combinations of the foregoing.

Please refer to fig. 1 to 4, the utility model provides a human infrared detection's of existence formula intelligent control ware, it is used in the illumination lamps and lanterns, and this intelligent control ware not only can detect the human body that gets into the detection zone, can also detect the human quiescent condition at the detection zone, and sensitivity is higher. The intelligent controller 100 comprises a fresnel lens 10 arranged at the front end of the intelligent controller, a circuit board 80 fixedly embedded in a space formed by a shell 20 and a bottom shell 22, and an input end 24 and an output end 26 arranged below the bottom shell 22. The circuit board 80 is provided with a human infrared sensor 30, a bluetooth module 40, an ambient light sensor 50, a microprocessor 60(MCU, or processing module) and a power module 70 for supplying power to the electronic components, in a direction toward the fresnel lens 10.

The Fresnel lens 10(Fresnel lenses) may be a general curved Fresnel lens or a flat Fresnel lens. The Fresnel lens utilizes the special optical principle of the lens to generate a blind area and a high-sensitivity area which are alternately changed in front of the detector so as to improve the detection receiving sensitivity of the Fresnel lens. When someone passes through the lens, the infrared rays emitted by the human body continuously and alternately enter a high-sensitivity region from a blind region, so that the received infrared signals are input in a pulse mode of being suddenly strong and weak, and the energy amplitude of the infrared signals is strengthened. The fresnel lens acts two ways: the first is focusing, i.e. refracting (reflecting) the infrared signal of human body on the infrared sensor 30, the second is dividing the detecting area into a plurality of bright areas and dark areas, so that the moving object entering the detecting area can generate the infrared signal of change on the infrared sensor 30 in the form of temperature change.

The number of the human body infrared sensors 30 may be one or more, for example, a plurality may be selected as needed. The human body infrared sensor 30 is manufactured and sold by hamman of germany.

The ambient light sensor 50 may be configured such that during the day or in the presence of a person, the ambient light sensor 50 sends a signal to the microprocessor 60, the microprocessor 60 sending a signal to turn off the LED light; at night or when the light is dark, the ambient light sensor 50 sends a signal to the microprocessor 60, and the microprocessor 60 sends a signal to turn on the LED lamp.

The input end 24 is two wires, the output end 26 is another two wires, and the output end is connected with an LED lamp (or referred to as an LED lighting lamp).

The power module 70 provides power support for the entire system. The utility model discloses in, the infrared ray gathers in human infrared sensor 30's probe through this fresnel lens 10, and the probe turns into the signal of telecommunication to infrared signal, amplifies through signal amplification circuit, does temperature compensation through temperature compensation circuit simultaneously, then sends microprocessor 60 to and handles.

It is understood that the vertical distance is adjustable, and is not limited to 3 meters, but may be 2 meters, 4 meters, 5 meters, and the like. Whether a human body stays or not is automatically judged according to the detected human body infrared ray intensity ratio, if the human body enters a detection area, the intelligent controller drives the LED illuminating lamp to work, when the human body stays in the detection area continuously and no matter the human body moves or is static, the intelligent controller continuously drives the LED illuminating lamp to keep normal work until the human body leaves the detection area, the intelligent controller drives the LED illuminating lamp to slowly enter an energy-saving mode and keep for a period of time, and finally the intelligent controller automatically drives the LED illuminating lamp to be turned off.

The utility model discloses an intelligent control ware, intelligent control that can the self-adaptation illumination lamps and lanterns, when someone gets into LED light detection area, the LED light slowly by dark bright, when the people continue to stop in the detection area and be in when removing or quiescent condition, the LED light keeps bright totally, leaves detection area completely until the human body, the LED light will slowly become to shine by bright totally and keep a period, then extinguishes. Through the ambient light sensor, the controller sends out a signal for turning off the LED lamp in the daytime or under the condition of people, and sends out a signal for turning on the LED lamp at night or in the dark.

The utility model discloses this kind of intelligent control ware wide application that existence formula human infrared detected is in various places such as school, library, office building, office, hotel, wisdom square.

The sequence numbers of the present invention are only for description, and do not represent the advantages and disadvantages of the implementation scenario.
