The **LXK2-PR14-R00** is a specific part number belonging to the **LUXEON K2** series of high-power LEDs, formerly manufactured by Philips Lumileds. This series was known for its robustness and high thermal endurance. --- ### 1. Technical Specifications The part number indicates a specific color, performance grade, and configuration. Below are the primary technical parameters for the LXK2-PR14-R00: | Parameter | Value / Description | | :--- | :--- | | **Manufacturer** | Philips Lumileds (now Lumileds) | | **Color** | Royal Blue | | **Peak Wavelength** | 450 nm – 460 nm | | **Radiometric Power** | Minimum 425 mW @ 700mA | | **Forward Voltage ($V_f$)** | 3.42V (Typical) to 3.85V (Max) | | **Test Current** | 1000 mA (Standard) | | **Max Drive Current** | Up to 1500 mA (with proper heatsinking) | | **Viewing Angle** | 140° (Lambertian radiation pattern) | --- ### 2. Breakdown of the Part Number The alphanumeric code follows a specific naming convention used by Lumileds: * **LXK2**: Identifies the **LUXEON K2** product family. * **PR14**: * **PR**: Represents the color (Royal Blue). * **14**: Represents the flux/radiometric power binning level. * **R00**: Refers to the mechanical configuration and packaging (usually an emitter on a circular base or specific reel format). --- ### 3. Key Electronic Features * **Thermal Management:** The K2 series was designed with a very low thermal resistance (approx. $9^{\circ}C/W$). This allows the LED to operate at higher currents without overheating, provided it is mounted on a metal-core PCB (MCPCB). * **High Current Operation:** Unlike standard 5mm LEDs, this part is designed to be driven at **1 Ampere** or higher. * **ESD Protection:** Built-in protection against electrostatic discharge, making it more durable during the assembly process. * **Material:** Built on InGaN (Indium Gallium Nitride) technology, which is the standard for high-efficiency blue and white LEDs. --- ### 4. Common Applications Due to its high output and specific "Royal Blue" wavelength, this component is commonly used in: 1. **Horticultural Lighting:** The 450nm wavelength is critical for chlorophyll absorption in plants. 2. **Remote Phosphor:** Used as a "pump" source to excite phosphors to create white light. 3. **Architectural Lighting:** Used in color-changing wall washers and stage lights. 4. **Aquarium Lighting:** Specifically for reef tanks to promote coral growth and fluorescence. ---
