Product Features :
Precision
This LED TV backlight strip (models: 2015 SVS39.5 FCOM FHD、LM41-00121X, etc.) features 8 high-quality LED chips arranged with ±0.1mm accuracy. The 775mm precise length matches the original structure of UE40J series TVs (UE40J5200AU, UE40J5000AU, etc.) perfectly, ensuring no modifications are required during installation. The 3V operating voltage provides stable output, with current fluctuations under ±2%, ensuring long-term stability.
Brightness
The 8 LED chips adopt high-efficiency technology, each providing 12 lumens, with the total brightness of the strip exceeding 96 lumens. The color temperature is stable at 6500K ±200K, meeting the D65 standard for white light. The 120° light angle, combined with professional optical design, achieves over 90% brightness uniformity, fully satisfying the display needs of 40-inch TVs.
Durability
The strip uses a widened and thickened aluminum substrate (1.2mm thickness) with excellent heat dissipation, featuring a thermal conductivity of 180W/m·K. The LED chips have a lifespan of over 50,000 hours, with light decay controlled to within 5%. The aluminum substrate is treated to be oxidation-resistant, with an operating temperature range of -20°C to 80°C, suitable for various home or commercial environments.
Energy Efficiency
The operating voltage is only 3V, with each LED consuming less than 1.2W, and the total power of the strip is under 9.6W. This results in more than 40% energy savings compared to traditional CCFL backlights, while providing superior brightness and color performance—balancing power efficiency and display quality for daily use.
Compatibility
Designed specifically for Samsung UE40J series TVs, it is fully compatible with models such as UE40J5200AU, UE40J5200AF, UE40J5000AU, UE40J5000AW, and UE40J5000AK. The electrical interface follows the original standard, supporting plug-and-play installation without the need for circuit modifications or additional adapters.
Stability
The voltage range of 2.8V-3.2V allows stable lighting even during slight voltage fluctuations in the power supply. The constant current drive design ensures consistent brightness for all 8 LEDs, with brightness variations of less than 3%. Performance remains stable after 2000 hours of high-temperature (80°C) and high-humidity (90% RH) testing, avoiding issues like flicker or brightness decay.
Quality
Each LED TV backlight strip undergoes 72-hour continuous aging tests, with a pass rate of 99.9% to eliminate defective products. It adopts lead-free soldering technology and meets RoHS environmental protection standards, complying with global eco-friendly requirements. The 3 pieces/set configuration provides backup parts for future maintenance, reducing the hassle of re-purchasing.
