Smart home lighting system

Abstract

The present invention discloses a smart home lighting system. The system comprises a LED lamp, a coordinator and a monitoring center. The LED lamp is internally provided with a circuit board, the circuit board is provided with a single chip microcomputer and a temperature sensor, an illuminance sensor, an infrared sensor, a relay circuit, a wireless communication module, a LED drive circuit and apower module which are connected with the single chip microcomputer, the wireless communication module is connected with the coordinator, and the coordinator is connected with the monitoring center through a RS422 interface; and the power module comprises a voltage input end, a first resistor, a second resistor, a first voltage stabilizing diode, a second voltage stabilizing diode, a third diode,a third resistor, a first operational amplifier, a direct current power source, a first triode, a second triode, a first capacitor, a first MOS tube and a voltage output tube. The smart home lightingsystem is simple in circuit structure, low in cost, convenient to maintain and high in circuit safety and reliability.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a lighting system for smart home. Background technique [0002] The lighting control system of smart home is actually to control the lighting according to the function of a certain area, different time of day, outdoor brightness or the purpose of the area, which is the basic part of the whole smart home. Smart lighting systems can be preset, that is, have the function of changing the lighting level into a series of settings. These settings, also known as scenes, can be automatically recalled by dimmer systems or central building control systems. For home use, this could take the form of an integrated central controller, possibly with a touchscreen interface. [0003] Generally speaking, as the core part of the entire smart home, the intelligent lighting system is especially suitable for large-area housing, and it will make life more convenient and comfortable. Lighting control system...

AI Technical Summary

Problems solved by technology

The power supply circuit of the traditional intelligent lighting system uses many components, the circuit structure is complex, the hardware cost is high, and it is inconvenient to maintain

In addition, because the power supply circuit of the traditional intelligent lighting system lacks corresponding circuit protection functions, such as: current limiting protection function and anti-interference signal function, the safety and reliability of the circuit are poor
