The **FLM-166-R** is a specific electronic component typically categorized as a **Linear LED Module** or a **Constant Current LED Strip**, often used in commercial lighting fixtures, signage, or architectural accents. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The FLM-166-R is designed for high-efficiency illumination. It integrates multiple Light Emitting Diodes (LEDs) onto a rigid or semi-rigid PCB (Printed Circuit Board). | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | Linear LED Module / Light Engine | | **Input Type** | Constant Current (CC) | | **Configuration** | Series/Parallel LED Array | | **CRI (Color Rendering Index)** | Typically 80+ or 90+ | | **Thermal Management** | Aluminum-clad PCB (MCPCB) for heat dissipation | --- ### 2. Key Electronic Characteristics #### A. Driving Method (Constant Current) Unlike standard 12V/24V strips that use resistors, the FLM-166-R usually requires a **Constant Current LED Driver**. * **Precision:** Ensures uniform brightness across the entire length. * **Protection:** Prevents "thermal runaway" by limiting the current even as the LEDs heat up. #### B. Circuit Layout The "166" in the part number often refers to the physical length (e.g., 166mm) or the number of diodes in a specific configuration. * **On-board Connectors:** Most versions feature poke-in wire connectors (like WAGO or Molex) for tool-less assembly. * **Voltage Drop:** Designed with low-resistance traces to minimize voltage drop over the module. #### C. Photometric Properties * **Luminous Flux:** High lumen output per watt (lm/W), making it an energy-efficient alternative to fluorescent tubes. * **Binning:** Usually follows MacAdam Ellipse (3-step or 5-step) to ensure color consistency between different modules. --- ### 3. Application and Installation The "R" suffix often denotes **RoHS compliance** or a specific **Rectangular** form factor. 1. **Heat Sinking:** Because these modules operate at high power densities, they must be mounted to a metal surface (heat sink) to ensure longevity. 2. **Wiring:** Usually wired in series. If connecting multiple modules, the driver's output voltage must be the sum of the modules' forward voltages ($V_f$). 3. **Dimming:** Compatible with PWM (Pulse Width Modulation) or 0-10V dimming through the external constant current driver. --- ### 4. Technical Comparison | Part Component | Purpose | | :--- | :--- | | **Substrate** | Aluminum or FR4 (provides structural integrity). | | **SMD LEDs** | The light source (usually Mid-Power LEDs). | | **ESD Protection** | Some variants include Zener diodes to protect against static. | | **Connectors** | Facilitate daisy-chaining modules. |
