Embodiment Construction

[0012] see figure 1 , the present invention includes: the present invention includes a power supply part, an Ethernet access part, a Bluetooth receiving part, a microcontroller part, a memory part, and an LED driving part. The microcontroller uses a single-chip microcomputer, which can send out multiple PWM signals (such as ATmega48 or a higher-end single-chip microcomputer of the same series), and plays the role of the control core. The single-chip microcomputer receives the interrupt control signal from the Ethernet module and the Bluetooth module, triggers the single-chip microcomputer to execute the corresponding interrupt, and converts it into a corresponding PWM output signal and outputs it to the LED driver chip.

[0013] see figure 2 , the Ethernet access part in the present invention is made up of NAT (network address port translation equipment), RJ45 interface, isolation filter 20F001N and network converter RTL8019AS. RJ45 is the network interface, which is connec...

Abstract

The invention relates an LED (Light Emitting Diode) indoor lighting dimming control system based on a mobile phone, which comprises a microcontroller, a memory, an Ethernet module, a Bluetooth module, an LED driver and a power source part. The microcontroller takes charge of controlling and coordinating the work of the all modules; the memory is used for memorizing network data and user configuration information; the Ethernet module is connected with an internet and used for receiving transmitted signals; the Bluetooth module is used for receiving the control information transmitted by the Bluetooth of the mobile phone and is in communication with the microcontroller by a serial interface; and the three-path LED driver is used for receiving PWM (Pulse-Width Modulation) dimming signals so as to regulate the brightness of a three-color LED. According to the LED indoor lighting dimming control system, the mobile phone is taken as a terminal and can control an indoor LED lamp. When a user is in a room, the mobile phone is in communication with the system through the Bluetooth function so as to regulate the brightness of various paths of indoor LED lamps and further achieve the purpose of making the eyes of people comfortable. When a user is far away from the system, the user can login the WEB of the system to configure the system through the GPRS function of the mobile phone, so that the same effect can be achieved.

Description

technical field [0001] The invention relates to an indoor LED lighting control system, in particular to an indoor LED lighting system controlled by a mobile phone. technical background [0002] With the continuous advancement of science and technology, indoor lighting has more and more humanized functions, especially represented by the function of changing color temperature in modern lighting systems. Color temperature is the human eye's perception of illuminants or white reflectors. This is a feeling of complex factors in physics, physiology and psychology. Adjusting the color temperature of the lighting can give people a comfortable feeling, which can make the office more comfortable. The staff in the living room can feel comfortable and improve work efficiency; the staff in the living room can get a full rest and eliminate fatigue; at the same time, in indoor public places such as KTV and exhibition halls, the color of the lighting fixtures can also match the theme, Impr...
