As a lighting tool in our daily life, desk lamp not only provides great convenience to our life, but also enriches our world. With the rapid development of electronic products, household appliances are gradually becoming more intelligent, and table lamps are also becoming more intelligent. The smart desk lamp uses a 2.4g packaged chip as the main control chip to realize the function of the remote control console light.
Yufanwei brought you an infrared remote control bedroom bedside atmosphere lamp development plan design today. The following is a detailed introduction to the plan.
1. The development principle of the 2.4g infrared remote control bedroom bedside ambient light solution
The light control touch panel of the infrared remote control bedroom bedside ambient light solution uses the SSOP20 packaged Yufan micro 2.4g package chip as the main control chip.
Hardware system composition: external USB-TYPE-C input DC5V, 3.7V lithium battery, charging management, a middle touch button, a slider (composed of 8 touch buttons), two 2.4g sealed chips, 4 PWM port output Control white light, R, G, B LEDs respectively.
2. Infrared remote control bedroom bedside ambient light solution function
The infrared remote control bedroom bedside ambient light solution designed by Yufan Micro adopts 2.4g packaged chip chip. Engineers design the circuit and build functional modules to realize the function of infrared remote control bedroom bedside ambient light.
The function introduction is as follows:
(1) Power-on default shutdown state;
(2) Button function:
1. Middle touch button: long press to switch the light;
Short press to switch color temperature, warm white 100%→RGB colorful breathing→RGB colorful gradient, and so on;
2. Slider: adjust the brightness down in the warm white state (sliding is only effective, clockwise to brighten, counterclockwise to darken);
Color temperature in RGB mode;
(3) Products with batteries need to be low power consumption;
(4) Color temperature and brightness with non-power-off memory;
(5) The product has a low-voltage 3V shutdown function;
(6) The brightness of the color temperature switch remains unchanged;
(7) Lithium battery with charging management, using AP5056, the red indicator light is on during charging, and the green indicator light is on when fully charged;
(8) Multi-mode control of infrared remote control switch.
The above is the case of the development and design of the 2.4g remote control bedroom bedside ambient lamp MCU solution shared by Shenzhen Yufan Microelectronics. If you need a development plan or a 2.4G packaged chip, please contact Yufan customer service.
