The **LPB-R0112051S-ARW** is a specific technical part number, typically associated with an **LED Backlight Bar** or a **lighting strip assembly**, often used in industrial displays, medical monitors, or specialized signage. Below is a breakdown of its electronic characteristics and construction. --- ### 1. General Specifications While specific data can vary by manufacturer (often associated with brands like *Lumberg* or specialized LED vendors), the alphanumeric code typically follows this logic: | Feature | Specification (Typical) | | :--- | :--- | | **Component Type** | LED Rigid Strip / Backlight Assembly | | **Input Voltage** | Typically 12V or 24V DC | | **Color Temperature** | Usually Cool White (approx. 5000K - 6500K) | | **Mounting** | SMD (Surface Mount Device) on PCB | | **Connector Type** | Wire-to-Board or Solder Pads | --- ### 2. Key Electronic Components #### A. LED Die (The Light Source) The strip utilizes high-efficiency Surface Mount LEDs. These are semiconductors that convert electrical energy into light. * **Phosphor Coating:** To achieve the "S-ARW" (often denoting a specific White binning), the blue LED die is covered with a yellow phosphor layer. * **Thermal Management:** The LEDs are mounted on an **MCPCB** (Metal Core Printed Circuit Board), usually aluminum, to dissipate heat away from the diodes. #### B. Current Limiting Resistors To prevent the LEDs from burning out due to thermal runaway, the board contains SMD resistors. These components regulate the current flowing through each series of LEDs. #### C. Protective Diodes (Optional) Some versions include a **TVS (Transient Voltage Suppressor)** diode to protect the strip from voltage spikes or ESD (Electrostatic Discharge) during installation. --- ### 3. Pinout and Connectivity The "1205" in the part number often refers to the physical dimensions or the LED density. Connection is usually handled via: 1. **Anode (+):** Positive DC input. 2. **Cathode (-):** Ground/Return path. --- ### 4. Technical Summary Table | Category | Details | | :--- | :--- | | **Substrate Material** | Aluminum (for heat dissipation) | | **Circuitry** | Series-Parallel combination | | **Application** | LCD Backlighting, Edge-lit displays | | **Compliance** | RoHS Compliant (Lead-free) | ---
