IOT desk lamp design

 With the rise of IOT, more and more home devices are connected to the cloud through gateways or routers. Users can control and monitor home devices thousands of miles away. Lamps naturally have IOT genes, are used frequently, and are powered 7X24. They do not require By laying network cables or wires alone, as long as there is a router or gateway, you can easily access the cloud and achieve remote control. Because it has the IOT function, the desk lamp can be given more new functions. The desk lamp is no longer just a lighting device but also a family companion that can be played with at will. Through the APP, various cool lighting effects and functions can be realized, such as scheduled power on and off, and the whole family. When traveling, the lighting conditions of a home are simulated, and criminals use the lights to think that there is someone in the home and become frightened. Cool lighting effects and simulate the sun's rhythm in nature. All these functions can be controlled and function converted through the mobile APP and the BLE connection of rs10.

RSL10 QFN EVB is used as the main control of IOT lamps. Because the GPIO of RSL10 is limited, the data protocol adopts single-line return-to-zero code communication method. The system only needs one GPIO1 as the LED RGBW driver. GPIO is used to drive WS2812. WS2812 is a control circuit and An intelligent externally controlled LED light source with integrated light-emitting circuit. Its appearance is the same as a 5050LED lamp bead, and each component is a pixel. The pixel contains an intelligent digital interface data latch signal shaping amplification drive circuit, a high-precision internal oscillator and a 12V high-voltage programmable constant current control section, which effectively ensures that the color of the pixel light is highly consistent. , the other ADC port is used to collect the temperature of the lamp, and when the temperature exceeds the limit standard, it automatically reduces the luminous efficiency of the lamp to avoid burning out the LED due to excessive temperature.
