Human body infrared microwave sensing night lamp

Abstract

The invention discloses a human body infrared microwave sensing night lamp. The human body infrared microwave sensing night lamp comprises an LED lighting circuit and is characterized by further comprising an AC-DC conversion power circuit, an ambient light detection circuit, a human body microwave sensing circuit, a PIR (Pyroelectric Infrared Sensor) circuit and a signal analysis control chip, wherein the AC voltage input end of the AC-DC conversion power circuit is connected with commercial power; the ambient light detection circuit, the human body microwave sensing circuit, the PIR circuit and the LED lighting circuit are connected with the signal analysis control chip respectively. The human body infrared microwave sensing night lamp has the benefits that 1, when a person has a rest at night, the lamp is in an extinguished state, and the vision development, the sleep quality and the growth development of a child are not affected; 2, when the person carries out activities in an insufficient light environment or at night, the night lamp is in a lightened state, and an auxiliary lighting function is not affected; 3, in a general mode, the sensing range is free from a dead corner, the problem that the night lamp cannot perform normal auxiliary lighting due to signal blockage is solved, and the night lamp is more convenient to use.

Description

technical field [0001] The invention relates to a night light, in particular to a small human body infrared microwave induction night light, which belongs to the technical field of lighting. Background technique [0002] Sleeping with the lights on at night will cause a kind of "light pressure" in the human body, which will affect the normal metabolic functions of the human body, including normal physiological and biochemical reactions in the body, and even make the heartbeat, pulse, and blood pressure of the human body abnormal, leading to diseases. For infants and young children, it is especially bad to sleep with the lights on. Any artificial light source will produce a very subtle light pressure. The long-term existence of this light pressure will make people, especially infants and young children, appear restless and restless, making it difficult to fall asleep and sleep quality is not good. At the same time, letting infants and young children sleep under the light for...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the harm caused by the long-time opening of the existing night light, overcome the problems that the sensing range of the existing night light has a blind area, and the sensing signal will be blocked by objects, etc., and provide a device that can not only serve as The use of auxiliary lighting can supplement people when the light is insufficient, and can guide nighttime activities. It can also ensure that people are in a state of turning off the lights when they rest at night without affecting the rest of the human body, and the induction signal will not be blocked by materials other than metal. Infrared microwave induction night light for human body, at the same time it has the characteristics of power saving, energy saving, stable and reliable
