The **LEDRO50M** is a high-performance, ring-shaped LED lighting unit typically used in machine vision, microscopy, and industrial inspection. It is designed to provide uniform, shadowless illumination for cameras. --- ### Technical Specifications Below are the primary electronic and optical characteristics for the LEDRO50M: | Parameter | Specification | | :--- | :--- | | **Input Voltage** | 24V DC (Standard for industrial controllers) | | **Power Consumption** | Approx. 2.4W - 3.0W (depending on color/model) | | **Outer Diameter** | 50 mm | | **Inner Diameter** | 22 mm - 25 mm (Clearance for lens) | | **LED Color Options** | White (W), Red (R), Blue (B), Green (G), or Infrared (IR) | | **Connector Type** | M8 3-pin or 4-pin connector / Open leads | --- ### Key Electronic Components #### 1. Light Emitting Diodes (LEDs) The unit consists of high-density Surface Mount Device (SMD) LEDs arranged in a circular array. * **Wavelengths:** Red (approx. 630nm) is common for high-contrast inspection, while White is used for general color reproduction. * **Longevity:** Rated for approximately 50,000 hours of continuous operation. #### 2. PCB Architecture The LEDs are mounted on a circular **Metal Core PCB (MCPCB)**. This design is crucial for thermal management, as it conducts heat away from the LEDs toward the aluminum housing, preventing thermal degradation and ensuring light intensity stability. #### 3. Current Limiting and Regulation * **Resistor Networks:** Basic models use precision resistors to balance current across LED strings. * **Strobe Compatibility:** The electronics are designed to handle "overdriving" (applying higher voltage for short pulses) when connected to a specialized strobe controller to increase brightness for high-speed shutters. #### 4. Housing and Protection * **Material:** Anodized aluminum body. * **Polarity Protection:** Usually includes diode protection to prevent damage if the 24V DC input is wired backward. --- ### Wiring Configuration While colors vary by manufacturer, a standard 24V DC setup for these industrial ring lights usually follows this logic: ```yaml Pin 1 (Brown): +24V DC Pin 3 (Blue): 0V (GND) Pin 4 (Black): Control/Trigger (If 4-pin configuration) ``` ### Integration Tips 1. **Heat Sinking:** Ensure the ring light is mounted to a metal bracket if running at 100% duty cycle to extend component life. 2. **Controller:** Use a constant current driver rather than a constant voltage source for the most stable illumination levels. ---
