The **LXK2-PL12-R00** is a specific part number belonging to the **LUXEON K2** series of high-power LEDs, originally manufactured by Lumileds. While this series is largely considered legacy (replaced by the LUXEON TX, M, or V series), it remains a significant component in the history of high-brightness LED development. --- ### Technical Specifications Below are the primary electrical and optical characteristics for the LXK2-PL12-R00: | Parameter | Specification | | :--- | :--- | | **Color** | Amber (Red-Orange range) | | **Dominant Wavelength** | ~590 nm | | **Luminous Flux** | Typically 35 - 55 Lumens @ 350mA | | **Forward Voltage ($V_f$)** | 2.19V (Min) to 3.51V (Max) | | **Test Current** | 350 mA | | **Max Drive Current** | Up to 700 mA (with adequate heat sinking) | | **Viewing Angle** | 140° (Lambertian) | | **Package Type** | Surface Mount (SMD) with integrated slug | --- ### Core Features 1. **Thermal Management:** The K2 series was known for its "Cold Start" capability and its robust thermal design. It features an electrically isolated thermal pad (slug) which allows for easier heat dissipation without short-circuiting the electrical traces. 2. **High Drive Current:** Unlike standard 5mm LEDs, these were designed to be driven at very high currents to produce intense illumination. 3. **Durability:** Built to withstand high junction temperatures (up to 150°C), making them suitable for automotive and industrial environments. ### Pinout and Mechanical Structure The LXK2-PL12-R00 has a unique physical footprint compared to modern compact LEDs: * **Anode/Cathode Leads:** Large "wing" style leads for soldering. * **Heat Sink Slug:** A large circular metal base on the bottom that **must** be soldered or thermally bonded to a Metal Core PCB (MCPCB) or heat sink to prevent the part from burning out within seconds. --- ### Common Applications * **Automotive:** Signal lights, rear combination lamps (RCL), and emergency vehicle lighting. * **Signage:** High-visibility amber beacons and traffic signals. * **Architectural:** Decorative facade lighting where high-intensity amber color is required. ---
