Body automatic sensing LED light

Abstract

The invention discloses a body automatic sensing LED light which is invented for solving the problems of high energy consumption, separation of incandescent bulbs and switches and the like in the prior art. The body automatic sensing LED light comprises a light holder, a shell and at least one LED luminous tube; a circuit board is arranged in the shell; an aluminum base plate is connected to the lower side of the circuit board; a circuit assembly is arranged on the circuit board; a pyroelectricity infrared sensor and a photodetector are arranged on the bottom surface of the aluminum base plate; the LED luminous tubes are all arranged on the bottom surface of the aluminum base plate; and a lens is arranged under the pyroelectricity infrared sensor. With the structure, the body automatic sensing LED light is switched in a commercial power 220V lamp holder, a circuit is rectified and filtered by an effective electronic transformer; a sensing signal is combined with the photodetector after being subjected to coupling signal processing, voltage amplification and shaping so as to realize the breakthrough of 90 percent of the commercial power conversion efficiency, large illumination, long service life and static micropower consumption. When the light is turned off when meeting the environment illumination in the day light, the light cannot turn on even if people moves in a light movement area; when no light is emitted at night, people can automatically trigger and turn on the light and the light is turned off in a delay way when people leaves, and the light works in cycles. The invention has the advantages of economical efficiency, practicability, environmental protection and energy conservation.

Description

technical field [0001] The invention relates to the technical field of semiconductor lighting lamps, in particular to a human body automatic induction LED lamp. Background technique [0002] Lighting is a necessity in people's daily life and work. It is self-evident that it has a wide range of applications, a long time and a high frequency. The power consumption is also a huge number. In order to actively respond to the country's energy conservation and emission With the development of a new economy, the "incandescent lamp" with high energy consumption is gradually banned, and the new form of green lighting and energy-saving products is vigorously promoted. However, there are existing split "human body sensor switches" and "sound and light control switches" to control the replacement of incandescent lamps. The problem of LED lighting lamps solves the problem of energy saving of "long-term lighting". Contents of the invention [0003] In order to overcome the above-mention...
