The **HLMP-EL10-R2000** is a high-intensity AlInGaP (Aluminum Indium Gallium Phosphide) LED manufactured by Broadcom (formerly Avago/Agilent). It is specifically designed for high-visibility applications, such as outdoor signage and traffic signals. --- ### 1. Key Technical Specifications | Parameter | Specification | |:---|:---| | **LED Color** | Amber (Orange-Yellow) | | **Wavelength** | 590 nm (Dominant) | | **Luminous Intensity** | 930 mcd to 2500 mcd | | **Viewing Angle** | 15° | | **Forward Voltage ($V_f$)** | 2.02V (Typ) to 2.4V (Max) | | **Forward Current ($I_f$)** | 20 mA (Test Current) | | **Package Type** | T-1 3/4 (5mm) Through-Hole | | **Lens Shape** | Round, Untinted, Non-diffused (Clear) | --- ### 2. Electronic Characteristics & Features * **AlInGaP Technology:** This material technology provides high luminous efficiency and stable light output over a wide temperature range. It is significantly brighter than older GaAsP technologies. * **Narrow Beam Pattern:** With a 15-degree viewing angle, this LED acts as a "spotlight." This makes it ideal for long-distance visibility but requires precise alignment. * **Thermal Stability:** The part is designed to handle elevated temperatures, which is critical for outdoor electronic displays exposed to sunlight. * **ESD Protection:** While robust, AlInGaP devices are sensitive to static; proper ESD handling during PCB assembly is recommended. --- ### 3. Application Use Cases Because of its specific optical and electronic profile, the HLMP-EL10-R2000 is commonly used in: 1. **Traffic Management:** Variable message signs (VMS) and pedestrian crosswalk signals. 2. **Commercial Signage:** Outdoor advertising boards where high brightness is required to compete with daylight. 3. **Industrial Indicators:** Status lights that need to be visible from a long distance or in bright factory environments. --- ### 4. Circuit Implementation Example When driving this LED with a standard 5V microcontroller or power supply, a current-limiting resistor is required. ```cpp // Calculation for Resistor (R): // R = (V_supply - V_f) / I_f // R = (5V - 2.02V) / 0.02A // R = 149 Ohms (Use 150 Ohm standard resistor) ```
