The **CLX6F-RKB** is a high-performance, surface-mount (SMD) Light Emitting Diode (LED) manufactured by **Cree LED**. It is specifically designed for high-resolution indoor and outdoor video screens, signage, and decorative lighting. --- ### 1. Technical Specifications The CLX6F-RKB is a **Tri-color (RGB) LED** housed in a PLCC6 package. Below are the primary technical parameters: | Parameter | Specification | | :--- | :--- | | **Package Type** | PLCC6 (Surface Mount) | | **Colors** | Red, Green, Blue (RGB) | | **Wavelength (Red)** | 619 - 624 nm | | **Wavelength (Green)** | 520 - 540 nm | | **Wavelength (Blue)** | 460 - 480 nm | | **Luminous Intensity** | Red: 450-900 mcd / Green: 900-1800 mcd / Blue: 224-560 mcd | | **Viewing Angle** | 120 Degrees | | **Water Resistance** | IPX8 Rated (Water resistant) | --- ### 2. Key Features * **Black Surface/Face:** The "B" in the suffix often denotes a black face or body. This is crucial for video displays because it increases **contrast ratios**, making the colors pop against the dark background. * **High Reliability:** It is designed to work in a wide range of environmental conditions, featuring an IPX8 rating which makes it suitable for outdoor applications when properly encapsulated. * **Common Anode/Cathode:** Typically configured with a common anode to allow for independent control of each color chip (Red, Green, and Blue). * **UV Resistance:** The encapsulation material is designed to minimize degradation from prolonged exposure to sunlight. --- ### 3. Application Use Cases The CLX6F-RKB is primarily used in the following electronic systems: 1. **Full-Color Video Screens:** Large-scale stadium displays or advertising billboards. 2. **Digital Signage:** High-density LED modules for retail or transit information. 3. **Decorative Lighting:** Architectural highlights where RGB color mixing is required. --- ### 4. Typical Circuit Connection To drive this LED, a constant current LED driver (like the MBI5024 or similar) is usually employed. ```cpp // Example of PWM Control Logic (Pseudo-code) void setLEDColor(int R, int G, int B) { analogWrite(RED_PIN, R); // Control Red Intensity analogWrite(GREEN_PIN, G); // Control Green Intensity analogWrite(BLUE_PIN, B); // Control Blue Intensity } ```
