## HLMP-CE26-R0ADD: Electronic Specifications and Overview The **HLMP-CE26-R0ADD** is a high-brightness Cyan (blue-green) LED produced by Broadcom (formerly Avago Technologies). It belongs to the HLMP-Cx2x series of 5mm (T-1 ¾) extra-bright lamps designed for outdoor signs and signals. --- ### 1. Key Technical Specifications Below are the primary electrical and optical characteristics of the device: | Parameter | Specification | | :--- | :--- | | **Color** | Cyan | | **Dominant Wavelength** | 505 nm (Typical) | | **Luminous Intensity** | 930 mcd - 2500 mcd (@ 20mA) | | **Viewing Angle** | 23° | | **Forward Voltage ($V_F$)** | 2.8V (Min) / 3.2V (Typ) / 3.8V (Max) | | **Forward Current ($I_F$)** | 30 mA (Maximum) | | **Power Dissipation** | 114 mW | | **Lens Shape** | Round, 5mm (T-1 ¾) | | **Lens Finish** | Clear, Non-diffused | --- ### 2. Physical Construction * **Package Type:** T-1 ¾ (5mm) through-hole package. * **Material:** InGaN (Indium Gallium Nitride) technology, which allows for high luminous efficiency in the blue and green spectrum. * **Lead Frame:** The leads are typically silver-plated for excellent solderability. * **Encapsulation:** High-temperature epoxy designed for durability and UV resistance, making it suitable for outdoor environments. --- ### 3. Key Electronic Features * **Precise Optical Design:** The 23° viewing angle provides a directed beam, making it ideal for variable message signs (VMS). * **Intensity Binning:** The "R0" in the part number indicates a specific luminous intensity bin, ensuring color and brightness uniformity when multiple LEDs are used in an array. * **Stability:** Designed for consistent performance across a wide temperature range ($ -40^{\circ}C$ to $+85^{\circ}C$). --- ### 4. Typical Applications * **Traffic Signals:** Due to the specific 505nm Cyan wavelength, it is often used in pedestrian "Walk" signals. * **Commercial Signs:** High-visibility outdoor advertising. * **Industrial Indicators:** Status lights requiring high visibility in daylight.
