The **HLMP-CB15-RSCDD** is a high-intensity, Blue Color LED manufactured by Broadcom (formerly Avago Technologies). It belongs to the **T-1¾ (5mm)** through-hole LED family, specifically designed for applications requiring high brightness and reliable performance in outdoor or high-ambient light conditions. --- ## 1. Technical Specifications The following table summarizes the key electronic and optical characteristics of the HLMP-CB15-RSCDD: | Parameter | Specification | | :--- | :--- | | **LED Color** | Blue | | **Wavelength (Typical)** | 470 nm (Dominant) | | **Luminous Intensity** | 520 mcd to 1500 mcd | | **Forward Voltage ($V_F$)** | 3.2V (Typical) / 3.8V (Max) | | **Forward Current ($I_F$)** | 20 mA (Test Current) | | **Viewing Angle** | 15 Degrees | | **Lens Shape/Size** | T-1¾ (5mm) Round | | **Lens Finish** | Clear, Non-diffused | | **Mounting Type** | Through-Hole | --- ## 2. Key Features * **High Luminous Efficiency:** Utilizes InGaN (Indium Gallium Nitride) technology to provide high light output per watt. * **Narrow Beam Pattern:** The 15-degree viewing angle concentrates the light into a tight beam, making it ideal for signaling and long-distance visibility. * **Environmental Stability:** The epoxy resin used is specifically formulated for resistance to high temperatures and humidity. * **Color Binning:** The "RSCDD" suffix denotes specific intensity and color bins, ensuring uniformity when multiple LEDs are used in a single display. --- ## 3. Pinout and Internal Structure The device follows the standard 5mm LED physical configuration: ```text ___ / \ | | <-- 5mm Clear Epoxy Lens |_______| | | | | Anode Cathode (+) (-) (Long) (Short/Flat side) ``` * **Anode (+):** The longer lead. * **Cathode (-):** The shorter lead, usually aligned with a flat spot on the base of the LED plastic housing. --- ## 4. Typical Applications Due to its high intensity and narrow viewing angle, this part is commonly found in: 1. **Variable Message Signs (VMS):** Highway and traffic information boards. 2. **Commercial Outdoor Advertising:** Large-scale LED billboards. 3. **Industrial Instrumentation:** Status indicators that need to be visible in direct sunlight. 4. **Specialty Lighting:** Decorative or architectural accents.
