The **LINEARCOLORMIX-OS-LM01M-R** is a high-performance linear LED module developed by OSRAM (now part of ams OSRAM). It is specifically designed for architectural lighting, signage, and decorative applications requiring dynamic color mixing. --- ## 1. Core Technical Specifications The module is built on a flexible PCB (Printed Circuit Board) and utilizes multi-chip LED technology to achieve uniform color blending. | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 24V DC | | **Color Control** | RGB (Red, Green, Blue) | | **Power Consumption** | Approx. 14.4W per meter (standard version) | | **LED Pitch** | 16.7 mm between centers | | **Beam Angle** | 120° | | **Mounting** | Self-adhesive 3M tape on the backside | | **Dimmable** | Yes (via Pulse Width Modulation - PWM) | --- ## 2. Key Electronic Components ### A. High-Performance LEDs The module uses SMD (Surface Mount Device) LEDs. These are usually 3-in-1 packages where the Red, Green, and Blue diodes are placed under a single lens. This ensures: * **Near-field color mixing:** Prevents "rainbow shadows." * **High Luminous Efficacy:** High brightness with low thermal output. ### B. Current Regulation (Resistors) To ensure the LEDs operate safely at 24V, the module integrates **Surface Mount Resistors**. * These resistors limit the current flowing through each LED string. * They are calculated to match the specific forward voltage ($V_f$) of the Red, Green, and Blue chips. ### C. Flexible PCB (FPC) The "Electronic Spine" of the module is a double-sided flexible copper laminate. * **Thermal Management:** The copper tracks are designed to act as a heat sink, dissipating heat away from the LED chips to prevent thermal degradation. * **Circuit Design:** It features a parallel circuit of series clusters. This means if one segment is damaged, the rest of the strip continues to function. --- ## 3. Connection and Control Wiring The LM01M-R follows a **Common Anode (+)** configuration. ```mermaid graph LR V(+) --> LED_R V(+) --> LED_G V(+) --> LED_B LED_R --> R_Channel(-) LED_G --> G_Channel(-) LED_B --> B_Channel(-) ``` ### Wiring Interface: 1. **Black/White Wire:** +24V (Common Anode) 2. **Red Wire:** Red Channel Ground 3. **Green Wire:** Green Channel Ground 4. **Blue Wire:** Blue Channel Ground --- ## 4. Usage Requirements To operate this electronic part, the following peripherals are required: * **Power Supply:** A constant voltage 24V DC driver (SELV rated). * **Controller:** A 3-channel PWM dimmer or a DMX/DALI to RGB decoder. * **Heat Dissipation:** While flexible, it is recommended to mount it on an aluminum profile for extended lifespan.
