Problems solved by technology

The infrared sensor generates an identifiable voltage signal after the infrared emitted signal touches the human body. Its defect is that the infrared sensor signal propagates along a straight line, and the emission angle is small, so it cannot generate an induction field in the sensing module area.
The microwave sensor can form a sensing area field around the sensor, but its production cost is high and the sensing area is limited.

Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing:

[0011] The LED induction lamp includes an induction part 1 and a lamp part 2. The induction part is composed of a light sensing module 3, a microwave induction module 4, and a data acquisition and processing unit 5. The lamp part is composed of an LED light source 6 and a power supply.

[0012] In the LED sensor lamp, the light sensor module 3 includes a photoresistor, which displays a high-resistance state under strong light conditions and a low-resistance state under weak light conditions. The power supplies are respectively the LED light source 6, the microwave sensing module 4 and the light sensing module 3 supplying power at the same time. Its working principle is to use photoresistors and microwave sensors to collect brightness and presence or absence signals, and use single-chip microcomputers to control the lighting and duration of lamps. When the surrounding envir...

Abstract

The invention discloses a light emitting diode (LED) induction lamp. The LED induction lamp comprises an induction part and a lamp part, wherein the induction part consists of a light induction module, a microwave induction module and a data acquisition and processing unit which are connected with one another; the lamp part consists of an LED light source and a power source which are connected with each other; the light induction module comprises a photosensitive resistor which displays a high-resistance state under the condition of strong light irradiation and displays a low-resistance state under the environment of weak light; a brightness signal and an attendance signal are acquired by using the photosensitive resistor and a microwave sensor; lighting and duration of the lamp are controlled by using a singlechip; when the surrounding environment is brighter, the power supply of the LED lamp is cut off; and when the surrounding environment is darker, whether a person exists around the lamp is judged, and the LED lamp is lighted if the person exists and is turned off if no person exists. The intelligent induction device is suitable for various occasions, and has the characteristics of high flexibility, anti-interference, silence, high response speed, long induction distance and the like.

Description

technical field [0001] The invention relates to the field of energy-saving lighting, in particular to an LED induction lamp which intelligently senses external light to realize automatic control. Background technique [0002] Energy saving and emission reduction are the primary considerations in the design and production of lamps. At present, many intelligent control lights have appeared in lighting and decoration, mainly using infrared sensors and microwave sensors. Infrared sensor generates an identifiable voltage signal after the infrared emitted signal hits the human body. Its defect is that the infrared sensor signal propagates along a straight line, and the angle of emission is small, so it cannot generate an induction field in the sensing module area. The microwave sensor can form a sensing area field around the sensor, but its production cost is high and the sensing area is limited. A new type of LED induction lamp is provided here to realize the intelligent contro...
