Based on the model number **IRS080-R55VF12**, this typically refers to a specialized **Industrial PoE (Power over Ethernet) Infrared Illuminator** often used in CCTV and security surveillance systems. Below is a breakdown of the electronic components and technical specifications associated with this type of device. ### 1. Technical Specifications The following table highlights the core parameters usually found in the IRS080 series: | Parameter | Specification | Description | | :--- | :--- | :--- | | **Input Voltage** | DC 12V / PoE (802.3af/at) | Dual power input capability. | | **LED Type** | High-Power SMT LEDs | Surface-mount technology for heat dissipation. | | **Wavelength** | 850nm (standard) | Near-infrared light (faint red glow visible). | | **Beam Angle** | 12° to 15° | Narrow beam for long-distance illumination. | | **Distance** | Up to 80 Meters | Effective range for nighttime visibility. | | **Power Consumption** | ~12W to 15W | Energy-efficient LED driver design. | --- ### 2. Key Electronic Components The device is composed of several critical internal sub-systems: #### A. The LED Array (Emitter) * **High-Intensity IR Diodes:** These are the heart of the unit. Unlike standard 5mm LEDs, these use high-power chips (typically 1W or 3W each) to push light over long distances. * **Collimating Lenses:** Each LED is paired with a specialized optical lens to focus the light into a specific beam angle (in this case, a narrow 12° spread). #### B. Power Management & PoE Module * **PoE Splitter Circuit:** Internal circuitry that extracts power from an Ethernet cable (48V) and steps it down to the operating voltage (usually 12V). * **Constant Current Driver:** LEDs are sensitive to voltage fluctuations. The internal driver ensures a steady current flows through the LEDs to prevent overheating and premature failure. #### C. Sensing and Control * **CDS Photocell:** A light-dependent resistor (LDR) that detects ambient light levels. It automatically triggers the IR LEDs to turn on at dusk and off at dawn. * **Thermal Management:** The housing (usually aluminum) acts as a large heatsink. Some high-end models include a thermal fuse or NTC thermistor to throttle power if the unit gets too hot. --- ### 3. Connection Interface | Port/Part | Function | | :--- | :--- | | **RJ45 Jack** | For PoE power and integrated network control (if supported). | | **DC Jack** | Alternative 12V power input for non-PoE setups. | | **Aluminum Housing** | IP66/67 rated protection against water and dust. | ---
