The remote control dimmable LED headlamp can adjust the brightness and color of the light at any time according to user requirements, thereby affecting the brightness of the indoor light, setting off different indoor environment atmosphere. It can save energy and reduce carbon emissions. LED is known for its low energy consumption and high brightness, and its brightness and energy consumption differ by more than 60% from traditional tungsten bulbs.
The LED dimmable system reference scheme is based on MindMotion’s MM32F0010 microcontroller and its system architecture is seen below:
- Remote control function is achieved through infrared/RF/Bluetooth and one or several of them are available
- The light intensity sensor collects the intensity of the ambient light to automatically adjust the brightness
- The color and brightness of LED lights can be adjusted according to PWM
