The **W2PV-C3SB1-R2** is a specific part number typically associated with professional-grade LED modules or lighting components, often found in signage, architectural lighting, or display backlighting systems. Below is an explanation of its electronic components and technical characteristics. --- ## 1. Component Overview This part is a high-efficiency **LED Module**. It is designed to be integrated into larger systems that require uniform illumination and long-term durability. ### Key Specifications | Feature | Description | | :--- | :--- | | **Component Type** | Constant Voltage LED Module | | **Input Voltage** | Typically 12V or 24V DC (Model dependent) | | **Light Source** | Surface Mount Device (SMD) LEDs | | **Color Temperature** | Usually Cool White or Neutral White | | **Ingress Protection** | IP66/IP67 (Weatherproof for outdoor use) | --- ## 2. Internal Electronic Parts The module consists of several critical electronic sub-components: ### A. SMD LED Chips The "C3" in the part number often refers to the number of LEDs (3 chips per module). These are high-performance semiconductors that convert electricity into light. They are binned for color consistency (MacAdam Ellipse steps). ### B. Current Limiting Resistors / ICs To protect the LEDs from overcurrent, the PCB includes: * **SMD Resistors:** Regulate the flow of current to each LED string. * **Constant Current Drivers (Optional):** Some variants use an onboard IC to ensure brightness remains consistent even if the input voltage fluctuates slightly. ### C. PCB (Printed Circuit Board) The circuitry is mounted on a **Metal Core PCB (MCPCB)**. Unlike standard fiberglass (FR4), the metal core acts as a heat sink to pull thermal energy away from the LEDs, extending their lifespan. ### D. Enclosure and Lens * **Polycarbonate Body:** Protects the electronics from moisture and physical impact. * **Optical Lens:** Most "W2PV" series modules feature a wide-angle lens (e.g., 160°) to spread light evenly and prevent "hotspots" in signs. --- ## 3. Electrical Connections The module is typically part of a "daisy chain" configuration. ```json { "wiring_type": "Parallel", "max_modules_per_string": 50, "polarity_marking": "Red (+), White (-)" } ``` ### Application Usage 1. **Channel Letters:** Illuminating the interior of 3D signage. 2. **Light Boxes:** Providing backlighting for translucent graphics. 3. **Architectural Accents:** Under-cabinet or cove lighting. ---
