LED lighting system for smart home

Abstract

The invention relates to an LED lighting system for a smart home. The LED lighting system comprises at least one LED lamp, a microprocessor, a pyroelectric infrared sensor module, a sound sensor module and a brightness sensor module, wherein the microprocessor is connected with the LED lamp, the pyroelectric infrared sensor module, the sound sensor module and the brightness sensor module; the microprocessor has three lighting modes; the pyroelectric infrared sensor module is used for detecting whether an indoor heat source sits up or lies down, thereby feeding back a signal to the microprocessor; and the sound sensor module is used for detecting an indoor sound frequency; and the brightness sensor module is used for detecting the indoor light brightness and controlling the LED lamp to turn on or off according to the detected sound and light brightness. The LED lighting system is high in intelligence and good in reliability; the lamp does not need to be manually turned on or off through intelligent management of the lighting system; the indoor light brightness and the sound frequency are dynamically and accurately detected to control light adjustment and to improve a sleep environment; and the practicability of the LED lighting system is greatly improved.

Description

Technical field [0001] The invention relates to a lighting system, in particular to an LED lighting system for smart homes. Background technique [0002] LED, light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor chip, one end of the chip is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin, and finally the housing is installed, so the LED lamp has good seismic performance . [0003] The semiconductor wafer is composed of two parts, one part is a P-type semiconductor, in which holes dominate, and the other end is an N-type semiconductor, which is mainly electrons. But when these two semiconductors are connected, a P-N junction is formed between them. When the current acts on the chip through the wire, th...

Problems solved by technology

[0005] However, the existing LED light systems are all ordinary on-off light systems. However, with the continuous progress of society, people are often no longer simply satisfied with obtaining sufficient lighting.

In addition, the control methods of lighting fixtures commonly used at present are relatively simple, and most of them require the user to manually operate the light switches all over the wall to realize the simple control of turning on / off the lighting fixtures, which is very inconvenient to use. First, it is still in a bright state after falling asleep, which is not conducive to sleepers entering deep sleep, and second, it is a waste of energy, which does not conform to the concept of energy conservation. Therefore, people automatically control lamps and combine various control methods except switch control. demand is also growing
