The **HLMP-EG30-R2000** is a high-intensity, T-1¾ (5mm) AlInGaP (Aluminum Indium Gallium Phosphide) LED manufactured by Broadcom (formerly Avago). It is specifically designed for high-visibility applications, particularly in outdoor environments. --- ### 1. Key Technical Specifications | Parameter | Specification | | :--- | :--- | | **Color** | Red (626 nm Typical) | | **Luminous Intensity** | 1500 mcd to 3500 mcd (at 20mA) | | **Forward Voltage ($V_F$)** | 1.8V (Typ) to 2.4V (Max) | | **Viewing Angle** | 30° | | **Lens Type** | Tinted, Non-diffused (Clear) | | **Material** | AlInGaP | | **Mounting Type** | Through-Hole | --- ### 2. Functional Characteristics * **High Luminous Output:** The AlInGaP technology provides high light output over a wide range of currents, ensuring visibility even in direct sunlight. * **Narrow Beam Pattern:** With a 30-degree viewing angle, this LED concentrates light into a directed beam, making it ideal for signage and long-distance signaling. * **Reliability:** Designed for high temperature and high humidity resistance, ensuring a long operating life in harsh outdoor conditions. --- ### 3. Application Use-Cases 1. **Variable Message Signs (VMS):** Used in traffic information boards. 2. **Commercial Outdoor Advertising:** High-brightness displays. 3. **Traffic Signals:** Due to its precise wavelength (Red) and longevity. 4. **Automotive:** Interior and exterior secondary lighting. --- ### 4. Typical Circuit Connection To operate this LED safely, a current-limiting resistor is required. Use the following formula: `R = (V_source - V_F) / I_F` ```c // Example Calculation for a 5V Source // V_source = 5V // V_F = 1.8V // I_F = 0.02A (20mA) R = (5 - 1.8) / 0.02 = 160 Ohms ```
