The **CWCBLPM1.W1** is a high-performance, multi-chip LED module belonging to the **OSRAM OSTAR Stage** family. It is specifically engineered for stage lighting, architectural illumination, and medical lighting applications where high luminance and compact design are required. --- ### 1. Key Technical Specifications The following table summarizes the primary electrical and optical characteristics of the CWCBLPM1.W1: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | ams OSRAM | | **Color Temperature** | Cool White (approx. 5600K - 6500K) | | **Typical Luminous Flux** | 1200 - 1500 lm (@ 1400 mA) | | **Forward Voltage ($V_f$)** | 12.0 V to 15.0 V (typical) | | **Max. Forward Current ($I_f$)** | 2500 mA | | **Max. Junction Temp ($T_j$)** | 150°C | | **Viewing Angle** | 120° (Lambertian emitter) | | **Package Size** | 5.9 mm x 4.8 mm x 1.23 mm | --- ### 2. Core Electronic Components & Architecture #### A. Multi-Chip Configuration Unlike standard single-die LEDs, the CWCBLPM1.W1 utilizes **four high-power chips** arranged in a series-parallel or strict series configuration (depending on the specific sub-binning). This allows for a very high lumen density from a very small emitting surface, which is critical for narrow-beam optics. #### B. Ceramic Substrate The chips are mounted on a **high-thermal-conductivity ceramic substrate**. This component is vital for: * **Heat Dissipation:** Efficiently moving heat from the junction to the heat sink. * **Insulation:** Providing electrical isolation while maintaining thermal pathways. #### C. Phosphor Conversion As a "Cool White" LED, it uses Blue InGaN (Indium Gallium Nitride) dies covered with a specialized yellow/green phosphor layer to convert blue light into a broad-spectrum white light. --- ### 3. Implementation Requirements To operate this part safely and efficiently, the following electronic considerations are necessary: * **Constant Current Driving:** Because LEDs are current-driven devices, a specialized LED driver is required to prevent "thermal runaway." * **Thermal Management:** Due to the high power density (up to ~30W), the module **must** be mounted to a metal-core PCB (MCPCB) and a substantial heat sink. * **Optical Pairing:** The flat glass window surface is designed to be used with secondary optics (TIR lenses or reflectors) to create sharp, concentrated beams. --- ### 4. Typical Applications * **Stage Lighting:** Moving heads, washes, and profile spots. * **Architectural:** High-intensity floodlighting and wall washing. * **Medical:** Surgical overhead lamps requiring high CRI and brightness.
