In today’s self-media video and live streaming industry, both professional photographers and video creators have higher demands for portable lighting equipment: lightweight, easy to carry, smart control, long battery life, and rich adjustment functions. The maturity of low-power Bluetooth (BLE) technology provides an ideal solution to meet these needs, especially with the emergence of high-performance, low-cost modules like the RC3526A from ZhiHan IoT, which offers excellent solutions to meet these demands, allowing users to transform into “light enhancers” and “light transformers”.
Solution
The core of the solution uses the RC3526A ultra-low-cost, low-power Bluetooth BLE5.3 module launched by ZhiHan IoT (RF Crazy). This module, with its competitive price of ≤4.8 yuan and industrial-grade performance, has become a good choice to meet the market’s cost sensitivity and stringent performance requirements.
-
Master-slave integration, one master with multiple slaves: The RC3526A supports master-slave integration mode, allowing “one master with five slaves” for multi-device connections. This means users can control up to 5 photography lights simultaneously through one master device (such as a mobile phone), making it ideal for multi-light collaborative lighting scenarios.
-
Bluetooth serial port transparent transmission (UART): The module supports serial port transparent transmission, greatly simplifying the development process. Users only need to develop the MCU and mobile APP logic to quickly achieve stable data communication between the device and the mobile App.
-
Rich AT command set: The RC3526A provides over 80 rich AT commands for configuring Bluetooth names, MAC addresses, broadcast parameters, etc. Its direct drive mode also supports 3 PWM control and IO flip commands, allowing direct driving of LED beads, adjusting brightness or color temperature without additional expansion circuits, simplifying product design.
-
Flexible OTA upgrade: The module supports over-the-air firmware upgrades (OTA), allowing potential issues to be easily fixed or features upgraded after the product leaves the factory, effectively enhancing the product’s lifecycle and user experience.
-
Low power consumption and high reliability: The RC3526A has a sleep current as low as 4.06μA, and supports broadcast and connection cycle modifications, alleviating the battery life anxiety of portable devices.
-
HID proximity unlock: The module supports HID Bluetooth proximity unlock function, allowing adjustment of the signal strength trigger threshold (with a trigger distance accuracy of ±0.5 meters and a false alarm rate of less than 0.1%). This is very useful for achieving smart interactive experiences such as “the light automatically turns on when picked up” or “automatic pairing with the camera when close”.
System Design and Implementation
Hardware Design
The lighting system uses high color rendering index LED beads to ensure true color reproduction. It supports dual color temperature (such as 2700K-6500K) and RGBW mixed color adjustment to meet the needs of different shooting scenarios.
Power management: Built-in high-capacity lithium battery with efficient charge and discharge management circuit.
Integration and control: The RC3526A module serves as the communication and control core, working in conjunction with the MCU. The MCU receives commands sent from the mobile APP via Bluetooth transparent transmission and uses the module’s control commands to drive LED beads, achieving adjustments in brightness, color temperature, and color.
Structural design: Adopts an inflatable soft light cover, portable panel light or tube light stick design. When inflated, it provides a large area of soft light, and when deflated, it can be folded for storage, making it compact and easy to carry.
Smart Control and Functions
Mobile APP: A dedicated APP is developed to connect to the RC3526A module via Bluetooth. Users can remotely adjust the brightness, color temperature, color (supporting RGB), working modes, and all other parameters on the App.
Multi-light networking and synchronization: Utilizing the RC3526A‘s “one master with five slaves” capability, multiple lights can be networked via Bluetooth. This allows for easy control of multiple lights during shooting, ensuring consistent color temperature and brightness, achieving complex lighting setups.
Smart scene modes: Pre-set various lighting effect modes, such as rainbow lighting effects, running lights, flashing, pulsing, and other effects, adding more creative possibilities for video production.
Application Scenarios
TVC commercial shooting, outdoor travel shooting, and Vlog creation: Lightweight and portable, it can easily fit into a backpack, providing high-quality fill light anytime and anywhere, enhancing the quality of the footage.
