### Analysis of CWCBLPM4.EN-MZNX-R The **CWCBLPM4.EN-MZNX-R** is a high-performance, multi-chip LED module from the **OSRAM OSTAR Stage** family, specifically designed for architectural, stage, and entertainment lighting applications. --- ### 1. Technical Specifications This component is an **RGBW (Red, Green, Blue, White)** LED module that allows for high-intensity color mixing from a compact point source. | Parameter | Specification Details | | :--- | :--- | | **Manufacturer** | ams OSRAM | | **Series** | OSRAM OSTAR Stage | | **Colors** | 4-in-1 (Red, True Green, Blue, White) | | **White CCT** | Cold White (approx. 5700K - 6500K) | | **Forward Current** | Max 1000 mA per chip | | **ESD Withstand Voltage** | Up to 2 kV per JESD22-A114-F | | **Package Size** | 5.9 mm x 4.8 mm x 1.23 mm | | **Viewing Angle** | 120° (Lambertian emitter) | --- ### 2. Key Electronic Features #### A. Multi-Die Configuration The module contains four separate LED chips (Red, Green, Blue, and White) integrated into a single high-reflective ceramic package. This allows for: * **Small Optical Footprint:** Ideal for use with secondary optics (lenses) to create narrow beams. * **Homogeneous Color Mixing:** Minimizes color shadows compared to discrete single-color LEDs. #### B. Thermal Management The device is built on a ceramic substrate with a low thermal resistance ($R_{thJS}$ approx. 2.8 K/W). This ensures that heat generated at the junction is efficiently transferred to the PCB, allowing the LEDs to be driven at high currents (up to 1A) without rapid degradation. #### C. Electrical Connections Each chip has its own anode and cathode connection, providing the designer with total control over each color channel via Pulse Width Modulation (PWM) for dimming and color tuning. --- ### 3. Part Number Breakdown (Nomenclature) The suffix **MZNX-R** refers to the specific binning for brightness and wavelength: * **MZ:** Luminous Flux / Intensity binning. * **NX:** Color/Wavelength binning for the specific colors. * **R:** Packaging/Reel information. --- ### 4. Typical Applications Due to its high power density, this part is commonly found in: 1. **Stage Lighting:** Moving heads, wash lights, and spots. 2. **Architectural Lighting:** Wall washing and decorative accent lighting. 3. **Mood Lighting:** High-end interior lighting systems. --- ### 5. Wiring Diagram Concept To drive this component, a 4-channel constant current LED driver is required. ```cpp // Logic representation for a 4-channel PWM Driver void setColor(int r, int g, int b, int w) { analogWrite(RED_PIN, r); // 0-255 analogWrite(GREEN_PIN, g); // 0-255 analogWrite(BLUE_PIN, b); // 0-255 analogWrite(WHITE_PIN, w); // 0-255 } ```
