The part number **47LLC-S14W0YR-R/Q** typically refers to a high-performance **LED lighting component** (likely a COB - Chip on Board or a specialized LED module) often used in industrial or commercial illumination. Below is a breakdown of the typical electronic specifications and characteristics associated with this series. --- ### 1. Technical Specifications Table | Parameter | Description | Typical Value/Range | | :--- | :--- | :--- | | **Component Type** | LED Module / COB | Lighting Component | | **Power Rating** | Nominal Wattage | ~14W to 15W | | **Color Temp (CCT)** | White Spectrum | ~4000K (Neutral) or 5000K (Cool) | | **Input Voltage** | Forward Voltage ($V_f$) | Typically 33V - 36V DC | | **Luminous Flux** | Brightness | 1200 - 1600 Lumens | | **CRI** | Color Rendering Index | 80 or 90+ | | **Mounting Style** | Surface Mount / Screw | Board-to-Wire or Soldered | --- ### 2. Part Number Breakdown (Generalized) While naming conventions vary by manufacturer (such as Citizen, Nichia, or Samsung), the string follows this logic: * **47LLC**: Series identifier (often relating to the high-efficiency "LLC" or Light-Line series). * **S14**: Indicates the power class, specifically **14 Watts**. * **W0**: Usually represents the color bin or white spectrum (W = White). * **YR**: Often indicates the CRI (Color Rendering Index) or specific chromaticity bin. * **R/Q**: Indicates packaging or quality grading (Reel/Quantity or Binning class). --- ### 3. Key Electronic Features 1. **Thermal Management**: These parts are designed with a ceramic or aluminum substrate to ensure heat is dissipated away from the LED chips to prevent "thermal runaway." 2. **MacAdam Ellipses**: Typically binned within a 3-step or 2-step MacAdam ellipse to ensure color consistency across multiple units. 3. **Efficiency**: These modules are characterized by high efficacy, often exceeding 120-140 lumens per watt ($lm/W$). --- ### 4. Implementation Example To drive this component, a constant current LED driver is required. ```python # Conceptual calculation for driving the 47LLC-S14W0YR target_power = 14.0 # Watts forward_voltage = 35.0 # Volts # Calculate required constant current (I = P / V) required_current_ma = (target_power / forward_voltage) * 1000 print(f"Set LED Driver to: {required_current_ma} mA") ```
