The intelligent desk lamp designed in this project is based on STM32F103C8T6 microprocessor as the core control unit, with several sensor modules to achieve various functions. The Working Principle and System Structure Diagram of Intelligent Desk Lamp The task of this project is to use the STM32 microcontroller as the control core, combined with the sensor module, design a lamp to achieve automatic lighting, intelligent dimming, remind to change the sitting posture, night light and other functions, through the wireless sensor transmission data and cell phone APP for real-time control of the lamp, with the collection of environmental parameters around the function of intelligent desk lamp, to achieve energy saving and convenience purposes.Ģ.1. Nowadays, the mainstream light sources are using LED lights for lighting. And in the process of bonding, light will be generated, the light-emitting phenomenon is caused by the release of photons. Fluorescent lamps, also known as fluorescent lamps, rely on phosphors on the inside of the lamp to adjust the color of light, and changing the type of phosphor can change the color of light emitted. Because the light emitted is very close to the spectrum of the sun, it can faithfully restore the original color of the displayed object. Īs the first electric lamp, the incandescent lamp is heated by energizing the filament, and when it becomes incandescent, the visible light is emitted by the thermal radiation generated by the filament. As a smart desk lamp, although most of them have integrated multiple functions that allow the lamp to be used in different situations, the core function of the lamp is still the ability to provide a comfortable lighting environment for the user. Smart desk lamps with pyroelectric detection can detect biological activity around them, and when there is no activity around, the lamp will turn off the lighting after a time delay. Those intelligent desk lamps with sitting sensing function can provide more scientific and intelligent lighting conditions. Traditional desk lamps only have simple lighting functions and require manual control of the lamp, which is a single function. As a household lighting device, the desk lamp is used very frequently and is essential in people’s daily study and work. In modern society, myopia caused by poor sitting posture such as hunchback is very common among adolescents, which causes a lot of inconvenience in daily life. While desk lamps are created for similar activities such as reading and writing, it is a movable lamp that provides localized lighting. Lighting affects the efficiency of work and study, and when people are in poor lighting conditions, they will be less efficient in work and study due to visual fatigue and other problems. Compared with traditional home appliances, smart appliances can not only be set and controlled according to the user’s needs, but can also perform personalized operations according to the user’s home environment and habits. Compared with the general traditional desk lamp, it solves the problems of traditional desk lamp control not simple enough, high energy consumption and being easy to cause visual fatigue or myopia therefore, it has high application value and market value.Īlong with the continuous development of technology and people’s rising standard of living and quality of life, people have begun to put forward more and more demands for home appliances, and the demand has gradually changed from the initial single function to the intelligent and simple operation design of home appliances. Desk lamp has the advantages of simple operation, energy saving, sitting posture reminder, automatic dimming and wireless control, etc. Finally, the automatic adjustment of lighting intensity, posture reminder, human infrared sensing and wireless control of the intelligent lamp are realized through a combination of hardware and software. The program design of each function by drawing program flowchart is completed. Then the interface circuit design of each functional module is completed by drawing schematic diagram through Altium Designer. Bluetooth module HC-05 is the wireless control module of the lamp. HC-SR04 ultrasonic distance measures sensor for distance measurement. The paper firstly analyzes the system scheme of the intelligent desk lamp and completes the hardware selection, using STM32F103C8T6 as the main control, HR-SR501 module as the pyroelectric module of the intelligent desk lamp. Compared with the general traditional desk lamp, intelligent desk lamps provide a more comfortable lighting environment for people to read, work and study. Table lamps provide the right amount of light for people to work and study in their daily lives. Table lamps have long been one of the necessities of people’s life and work, as they appear and are used very frequently in household lighting equipment.
