The **LUW F8BN-P2P3-R** is a high-performance, white Light Emitting Diode (LED) manufactured by **ams OSRAM**, specifically belonging to the **OSLON Black Flat** series. This component is engineered primarily for automotive lighting applications, such as high-beam and low-beam headlights. --- ### 1. Key Technical Specifications The part number indicates specific bins for luminous flux and forward voltage. Below is a breakdown of the core parameters: | Parameter | Value / Range | | :--- | :--- | | **Manufacturer** | ams OSRAM | | **Series** | OSLON Black Flat | | **Color** | Ultra White (InGaN Technology) | | **Luminous Flux (P2-P3)** | Approximately 210 lm to 280 lm (@ 1A) | | **Forward Current (Nominal)** | 1000 mA (1A) | | **Forward Voltage ($V_f$)** | 2.75 V to 3.50 V | | **Operating Temperature** | -40°C to +125°C | | **Package Size** | 3.75 mm x 3.75 mm x 0.5 mm | --- ### 2. Physical and Design Features The "Black Flat" series is named for its unique construction, which offers several mechanical advantages: * **SMT Package:** Surface Mount Technology with a ceramic substrate and a high-stability silicone resin lens. * **Black Package Body:** The black surface helps improve contrast and reduces stray light, which is critical for precision beam shaping in headlights. * **Thermal Management:** Features a very low thermal resistance (typ. 4 K/W), allowing it to dissipate heat efficiently even at high current densities. * **Leadless Design:** Utilizes a bottom-pad design for improved electrical contact and heat transfer to the PCB. --- ### 3. Part Number Decoding The suffix **"P2P3-R"** refers to the specific binning for this production run: 1. **LUW:** LED, Ultra White. 2. **F8BN:** The specific internal chip design and generation (OSLON Black Flat). 3. **P2P3:** The Luminous Flux bin (defines the brightness range). 4. **R:** Typically refers to the wavelength/chromaticity coordinate grouping (Color temperature). --- ### 4. Implementation Example (Basic Circuit) When driving this LED, a constant current source is required to prevent thermal runaway. ```python # Pseudo-code logic for a PWM LED Driver (Automotive MCU) def adjust_headlight_brightness(duty_cycle): # Standard OSLON Black Flat needs constant 1000mA # PWM frequency should be > 200Hz to avoid flicker set_pwm_signal(pin_A1, duty_cycle) if read_temp_sensor() > 110: # Degrees Celsius reduce_current() # Thermal protection ``` --- ### 5. Common Applications * **Automotive Exterior:** Main headlights (High/Low beam), Fog lights, and Daytime Running Lights (DRL). * **Industrial Lighting:** High-intensity flashlights or searchlights. * **Vision Systems:** High-speed camera illumination where high contrast and brightness are necessary.
