The **HLMP-EG30-R6000** is a high-performance, precision optical performance AlInGaP (Aluminum Indium Gallium Phosphide) LED manufactured by Broadcom (formerly Avago). It is specifically designed for high-brightness applications where sunlight viewability is critical. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and optical characteristics of the HLMP-EG30-R6000: | Parameter | Specification | | :--- | :--- | | **LED Type** | Through-Hole (T-1 ¾, 5mm) | | **Color** | Red | | **Dominant Wavelength** | 626 nm | | **Luminous Intensity** | 4200 mcd (typical) | | **Viewing Angle** | 30° | | **Forward Voltage ($V_F$)** | 1.8V to 2.4V | | **Forward Current ($I_F$)** | 20mA (typical) / 50mA (max) | | **Lens Shape** | Round, Non-diffused (Clear) | --- ### 2. Core Features & Materials * **AlInGaP Technology:** This material provides a very high luminous efficiency and stable light output over a wide range of temperatures and currents. * **Precision Optical Design:** The 30-degree radiation pattern is tightly controlled, making it ideal for message signs and signals where specific viewing zones are required. * **High Temperature Resistance:** Designed to operate reliably in outdoor environments, typically ranging from -40°C to +100°C. * **Moisture Sensitivity:** These LEDs are generally robust but should be handled according to IPC/JEDEC standards to prevent damage during soldering. --- ### 3. Application Use Cases Due to its high intensity and narrow viewing angle, this part is commonly used in: 1. **Variable Message Signs (VMS):** Traffic management and highway displays. 2. **Commercial Outdoor Advertising:** Large-scale LED billboards. 3. **Solar Powered Signs:** Due to high efficiency, it requires less power to achieve high visibility. 4. **Industrial Indicators:** Status lights that must be visible in bright factory environments. --- ### 4. Circuit Integration Example When integrating this LED into a circuit with a 5V power supply, you must use a current-limiting resistor. **Calculation:** `R = (V_source - V_forward) / I_forward` `R = (5V - 2.1V) / 0.02A = 145Ω` (Use a standard **150Ω** resistor). ```cpp // Example: Driving the LED via a PWM Pin (Arduino/Microcontroller) const int ledPin = 9; void setup() { pinMode(ledPin, OUTPUT); } void loop() { // Fade in for (int i = 0; i <= 255; i++) { analogWrite(ledPin, i); delay(10); } } ```
