Key Features of Flexible LED Light Sheet with Lens
1. Integrated Optical Lens for Wider and More Uniform Light Distribution
Each SMD2835 LED is paired with a precision optical lens, expanding the beam angle to 175° for exceptionally wide light distribution. Compared with standard LED light sheets, the lens design significantly reduces hotspots and improves illumination uniformity, making it ideal for slim light boxes, translucent panels and premium commercial displays where smooth backlighting is essential.
2. Flexible Double-Sided FPC for Curved and Irregular Surfaces
Manufactured with a double-sided flexible FPC PCB, the light sheet offers excellent conductivity and high current capacity while maintaining outstanding flexibility. It easily conforms to round, curved and uniquely shaped light boxes, making it an ideal lighting solution where rigid LED boards cannot be used.
3. High Brightness with Excellent Energy Efficiency
Equipped with 105 high-quality SMD2835 LEDs, this model delivers up to 3200–3500 lumens while maintaining an efficiency of 100–110 lm/W. The combination of high output and wide beam angle allows greater LED spacing, reducing the number of lighting modules required in many backlighting applications.
4. Convenient Installation with Multiple Wiring Points
Each module is designed with multiple soldering pads and connection points, making electrical wiring faster, cleaner and more reliable. The integrated 3M adhesive backing also simplifies installation while allowing additional fixing methods when required for commercial projects.

Flexible LED Light Sheet with Lens Wiring Diagram & Installation Guide
1. Main cable T-type connector is 2*2.5mm², which can over-current MAX 20A. (means that 240W single-ended connection at DC12V, 480W single-ended connection at DC24V)
2. The maximum current of connection terminal on FPC is 4-5A (60W (DC12V)). If the power is large, you should connect several power cable and jumper cable as required.
3. It is recommended to use a qualified switching power supply. (with short-circuit overvoltage, overload protection, and safety certification)
4. Please connect according to the positive and negative poles marked on the shell, the gray wire is connected to the positive pole of the power supply, and the white wire is connected to the negative pole of the power supply.
5. Switching power supply and controllers must work in a ventilated, dry environment, and switching power supplies generally only use 80% of the power.
Connection Methods and Installation Guide for Flexible LED Light Sheet with Lens
Our LED light sheets support two standard wiring configurations to fit projects of all sizes, with additional scalable solutions available for large-area installations. Both core setups are quick to install using the matching accessories below.
Method 1: Cascade connection Connection (Figure 1)
Ideal for compact layouts with a small number of LED light sheets.
1. Plug one end of the sheet-to-power connection wires into the terminal of an LED light sheet, and connect the opposite end to your power supply.
2. For multi-sheet setups: Use sheet-to-sheet connection wires to link the adjacent terminals of two LED light sheets. Repeat this step to cascade connection additional sheets in sequence.
Important Notice: The maximum cascade connection quantity per single circuit varies by product model. For DC 12V or 24V systems, always verify the exact limit in the product’s technical specifications. Exceeding this rating will cause noticeable voltage drop, uneven brightness along the run, and risk of power supply overload. For larger installations, upgrade to a higher-wattage power supply, use the branch wiring method below, or deploy multiple power supplies for zoned independent power delivery.
Method 2: Main Cable Branch Connection (Figure 2)
Recommended for large-area installations with a high volume of LED light sheets, to ensure stable performance and consistent light output across the full space.
1. Connect the main trunk line of the main cable connector to your power supply.
2. The main cable connector features multiple tap outputs to form independent branch circuits.
3. On each individual branch, follow the cascade connection steps from Method 1 to connect your LED light sheets separately.
This distributed wiring design minimizes long-run voltage drop and avoids overloading a single circuit. Note that this is not the only high-capacity solution — using multiple power supplies for zoned independent power is also a standard, reliable approach for extra-large or multi-zone projects.
Flexible LED Light Sheet with Lens for Cutting Matters and Suggestions
Our FPC LED light sheets can be trimmed to custom dimensions to fit your installation layout. Follow the guidelines below to avoid damaging the internal circuit and ensure normal operation.
✅ Valid cutting (left panel): Both straight cuts (horizontal / vertical along grid lines) and diagonal cuts are allowed, as long as you trim along designated unit boundaries to retain complete LED circuit groups. The diagram demonstrates correct diagonal cutting examples; straight perpendicular cuts along the grid also follow this valid cutting rule.
❌ Invalid cutting (right panel): Cutting through incomplete circuit units, or trimming a diagonal strip with only 1 LED group, will break the internal circuit and cause partial LEDs to malfunction.
Important Precautions
1. Cutting Unit Rules
• For straight cuts (horizontal or vertical along the grid lines, i.e. positive-direction cutting), the minimum valid cutting unit is 1 complete LED group.
• For diagonal cuts, the trimmed section must contain at least 2 complete LED groups. Cutting a single diagonal LED strip will break the internal circuit and cause LED failure.
• Always cut slightly beyond the marked cutting line for a clean full cut. Avoid cutting through connector positions whenever possible.
2. Cutting Operation
• Use sharp scissors and cut firmly through the full thickness of the FPC sheet. Trim away any burrs on cut edges before installation.
3. Installation Requirement
• Leave a 1–2 mm gap between adjacent cut FPC sheets during assembly. The sheets must not come into direct contact with metal surfaces.
3. Edge Insulation
• Seal and insulate all cut edges and exposed solder pads with insulating tape or adhesive to prevent short circuits.
