Product Description

The 5LED 3V 42.5cm Straight Backlight Strip is a precision illumination component designed for the efficient repair of LED televisions and various custom lighting applications. Measuring 42.5cm in length, this replacement strip is a versatile fit for numerous display panels that utilise a straight horizontal or vertical backlight array. Each strip features 5 high-intensity LED beads, each operating at 3V, providing uniform and flicker-free illumination. To ensure industrial-grade longevity, these strips are constructed on a high-grade aluminium substrate. This aluminium base provides vastly superior heat dissipation compared to standard plastic alternatives, effectively preventing LED burnout and common display issues such as dark spots or "sound but no picture."

Detailed Key Features

  • Universal 42.5cm Fit: The straight profile is specifically engineered to accommodate a variety of LED TV chassis sizes and DIY light box projects.

  • Aluminium Thermal Core: Built on an aluminium base that rapidly draws heat away from the LED chips, ensuring a stable operating temperature and an extended service life.

  • Consistent 3V Power Balance: Each LED is rated at 3V, making the strip fully compatible with standard 15V-range constant-current backlight drivers.

  • Precision Optical Lenses: Equipped with high-clarity diffuser lenses that spread light evenly across the panel, eliminating "bright spots" or "shadowing" effects.

  • Industrial Reliability: Engineered to withstand the high-temperature environment inside an active TV while maintaining original factory brightness and colour temperature.

All Technical Details

  • Total Drive Voltage: Approximately 15V DC per strip.

  • Substrate Type: Rigid aluminium (Al) for thermal stability and straightness.

  • Colour Temperature: Calibrated cool-white spectrum for natural colour rendering and high contrast.

  • Interface: Standard 2-pin interface for reliable electrical bonding or easy soldering.

  • Profile: Slim-line straight design for easy placement within original reflective sheets.

Prototyping & Engineering Tips (Robogears Exclusive)

  • Diagnosis Tip: If your TV has sound but the screen remains dark (or flashes briefly before going black), use an LED tester to check the strip. A 5-LED 3V strip should show a total forward voltage drop of roughly 15V.

  • The "Full Set" Rule: For any professional repair, we strongly recommend replacing the entire array (all strips) at once. Mixing new strips with old, aged ones can cause current imbalances that lead to the remaining older strips failing shortly after the repair.

  • Thermal Bonding: Ensure the metal chassis of the TV is perfectly clean of old adhesive residue before installation. Use high-quality thermal double-sided tape or thermal glue to ensure the aluminum strip makes maximum contact with the chassis for heat dissipation.

  • Project Idea: Due to the 42.5cm length and uniform light, these strips are also excellent for creating high-brightness workbenches, laboratory inspection lights, or specialized photographic light boxes.

Package Includes

  • 1 x 5LED 3V (42.5cm) Straight Backlight Strip
