Product Description

The 8LED (4+4) 80CM Backlight Strip is a professional-grade replacement solution designed for large-format LED televisions and custom architectural lighting. Measuring a total of 80cm, this strip utilises a convenient "4+4" segmented design, allowing for easier shipping and more flexible installation within various TV chassis models. Operating within a stable 21-26V range, it delivers high-brightness, flicker-free illumination across the display. To ensure maximum longevity, these strips are constructed on a premium aluminium substrate, which provides superior heat dissipation compared to standard fibreglass strips. This industrial-grade thermal management prevents the LEDs from overheating, preserving picture clarity and avoiding dark patches.

Detailed Key Features

Universal 80cm Profile: Specifically sized to fit a variety of LED TV models, typically ranging from 39-inch to 43-inch displays, depending on the layout.
Segmented 4+4 Design: The strip is divided into two 4-LED segments that join together, making it easier to handle during installation and more resistant to shipping damage.
Wide Voltage Compatibility: Designed to operate efficiently between 21V and 26V DC, making it compatible with most standard backlight driver boards.
Aluminium Thermal Substrate: Features an aluminium backing that rapidly draws heat away from the LED beads, significantly extending the component’s service life.
Optical Diffusion Lenses: Each LED is fitted with a precision lens that ensures light is distributed evenly, eliminating "bright spots" or "halo effects" on the screen.

All Technical Details

Joiner Style: Standard interlocking interface for a secure electrical and mechanical bond between segments.
Substrate Type: Rigid aluminium (Al) base for structural stability and heat dissipation.
Colour Temperature: Calibrated cool-white for natural display reproduction and high contrast.
LED Specification: High-lumen efficiency beads optimised for TV panel backlighting.
Installation: Slim-line design that fits easily under original reflective sheets and light guides.

Prototyping & Engineering Tips (Robogears Exclusive)

Diagnosis Protocol: If your TV has sound but no picture, or if the screen flashes briefly before going dark, use an LED tester to check the strip. A full 8-LED assembly should show a forward voltage drop within the 21V-26V range.
The "Full Set" Recommendation: For any repair at your Pimpri facility, we strongly recommend replacing all strips in the TV simultaneously. Mixing old and new strips can cause current imbalances, leading to the remaining old strips failing shortly after the repair.
Heat Management: Before securing the new strips, ensure the TV chassis is clean of old adhesive residue. For maximum cooling, use high-quality thermal double-sided tape or a thin layer of thermal adhesive to bond the aluminium strip to the metal backplate.
Soldering Tip: If you need to bypass the original connector, solder your wires to the designated pads on the aluminium strip quickly with a high-wattage iron to prevent heat from damaging the nearby LED lenses.

Package Includes

1 x 8LED (4+4) 80CM Backlight Strip (Two joined segments)
