3. Built-in Functional Circuit Modules

3.1 Isolated AC-DC Power Conversion Circuit

Adopts isolated transformer structure to convert mains AC into steady 24V DC power supply. Multi-stage capacitor and inductor filter components are equipped to restrain current ripple, realizing flicker-free lighting and stable fan rotation.

3.2 Dual Independent Relay Control for Fan & Light

Independent relay drive circuits are arranged for fan and LED light loads separately. The two functions work without mutual interference, supporting separate switch control of ventilation and lighting, as well as combined mode operation.

3.3 LED Light Dimming & Color Tuning Circuit

Dedicated constant current light adjustment circuit is reserved on the PCB, which supports brightness adjustment and color temperature switching of the matching annular LED light source to meet different indoor lighting demands.

3.4 DC Fan Multi-Speed Drive Circuit

Optimized drive logic matches the power demand of thin horizontal fan DC motors, realizing multiple adjustable wind speed modes to satisfy different air circulation requirements.

3.5 Buzzer Operation Prompt Module

Onboard buzzer component sends mild sound feedback after each function switching operation, realizing simple human-machine interaction for end users.

3.6 Comprehensive Multi-Layer Safety Protection Layout

The circuit embeds over-current, over-voltage, overload, short-circuit and abnormal temperature protection logic. It will automatically cut off power output when abnormal electrical signals are detected, lowering potential safety hazards during fan-light operation.

3.7 External Standard Wiring Terminals

Preset red, white and other external lead terminals for power input, fan motor and LED light connection, simplifying wiring procedures and adapting to automated assembly lines of home appliance factories.

4. Core Advantages of This Solution

4.1 Horizontal PCB Layout for Thin Fan-Light Housing

The long strip horizontal PCB outline is tailor-made to fit the ultra-thin internal installation cavity of mainstream flat horizontal fan-light fixtures. No large-scale mold modification is needed for most existing thin fan-light product lines.

4.2 All-in-One Integrated Multi-Function Design

Single PCB integrates power supply, fan drive and light control modules, eliminating the need for separate independent power boards and light drive boards. It reduces the quantity of spare parts required for finished product assembly, cutting raw material procurement and manual assembly costs.

4.3 Independent Dual-Relay Separate Control

Separate relay drive for fan and light avoids load interference during simultaneous operation, improving the running stability of finished fan-light products and reducing failure probability.

4.4 Mature Mass-Production Verified Circuit Scheme

All electronic components adopt standardized matching combinations validated by batch manufacturing. The circuit maintains consistent stable performance under long-hour continuous working conditions, assisting finished fan-light products to pass routine household electrical safety certification tests smoothly.

4.5 Universal 36W Power Matching Compatibility

The 24VDC 1.5A, 36W rated load capacity fits most mainstream thin horizontal fan-light motor and LED panel power configurations. Manufacturers can directly assemble this board without secondary circuit parameter adjustment.

4.6 Flexible Bulk Supply & OEM Customization Support

The ready-made HSH-DF20-002 model supports stable mass order delivery. Customized adjustments on fan speed gears, light color modes and control logic can be carried out according to product development demands from fan-light manufacturers.

5. Application Scope

This control board is exclusive matching electronic spare parts for DC horizontal integrated light fans. Applicable scenarios include core drive hardware for new thin fan-light product R&D, replacement maintenance circuit boards for finished ceiling fan-light fixtures, and supporting PCB accessories for lighting & ventilation appliance OEM & ODM manufacturers. It suits flat horizontal fan-light combos installed in living rooms, bedrooms, balconies and study rooms for integrated indoor lighting and air circulation.

6. Commercial Value for Fan-Light Manufacturers

  1. Mature finished integrated circuit board saves independent circuit R&D investment and shortens the development & market launch cycle of new horizontal fan-light products.
  2. Integrated power, fan and light control structure reduces assembly part types, improving factory assembly efficiency and lowering overall production expenses.
  3. Complete built-in filtering and multi-layer protection circuits simplify electrical safety certification procedures for finished products sold to different regions.
  4. Fixed horizontal PCB size and external lead terminal layout match most existing ultra-thin fan-light housing structures, avoiding costly large-scale mold revisions of original production lines.
