Product Description

The 81LED 12V 49CM Edge LED Strip is a precision-engineered illumination component designed specifically for edge-lit (side-lit) LED televisions and high-density industrial lighting applications. Measuring 49cm in length, this strip packs 81 high-intensity LED beads into an ultra-slim profile, providing a seamless and powerful light source. Unlike direct-lit backlights, this edge-lit strip is designed to sit along the inner bezel of the TV chassis. At Robogears, we ensure these strips are built on a high-grade aluminium substrate to manage the intense heat generated by such a high concentration of LEDs. This superior thermal dissipation protects the LEDs from premature dimming or burnout, maintaining the sharp contrast and consistent brightness required for modern display panels.

Detailed Key Features

High-Density LED Array: Features 81 LEDs in just 49cm, delivering an extremely concentrated and uniform light output without "dark spots."
Edge-Lit Specialised Design: Optimised for televisions where the backlight source is located at the edges, reflecting light through a light guide plate (LGP).
12V DC Operation: Designed for stable performance at 12V, making it compatible with various TV power boards and standard 12V DC power supplies.
Aluminium Thermal Substrate: The metal base acts as an integrated heat sink, rapidly conducting heat away from the LEDs to ensure industrial-grade longevity.
Slim-Profile Integration: Ultra-thin width allows for precise fitment within the tight side-channels of modern slim-frame TV chassis.

All Technical Details

LED Bead Type: High-lumen SMD LEDs optimised for optical clarity.
Substrate Type: Rigid aluminium (Al) for thermal stability and structural straightness.
Colour Temperature: Calibrated cool-white spectrum for vivid colour reproduction.
Input Interface: Solderable pads or standard connector pins for secure electrical bonding.
Luminous Uniformity: Precision-spaced LEDs ensure consistent light intensity across the entire 49cm length.

Prototyping & Engineering Tips (Robogears Exclusive)

Diagnosis Protocol: If your edge-lit TV has sound but one side of the screen is darker than the rest, or if the whole screen is dark, check the voltage at the strip connector. An 81-LED 12V strip should be tested with a dedicated backlight tester or a regulated 12V source.
The "Side Replacement" Rule: For any repair at your Pimpri facility, always verify if the TV uses a single strip or a pair. For balanced brightness, replacing both strips (if applicable) is recommended to avoid uneven illumination due to ageing.
Thermal Bonding Requirement: Because edge-lit strips generate significant heat in a small area, it is critical to use high-quality thermal double-sided tape or thermal adhesive. Ensure the strip is pressed firmly against the TV's metal frame to maximise heat transfer.
Optical Alignment: When installing, ensure the LEDs are perfectly aligned with the edge of the Light Guide Plate (LGP). Any misalignment can cause significant shadows or uneven brightness across the screen surface.
