Flexible LED Backlight Sheet 24V 28W for Signage & Countertops

Product Introduction

The USKYLED Flexible LED Backlight Sheet is a DC24V LED backlighting solution designed for signage, advertising lightboxes, countertops, marble surfaces, display panels and other applications requiring broad-area illumination.

The sheet uses SMD2835 LEDs arranged on a flexible substrate, providing a thin and adaptable alternative to conventional rigid LED panels. The standard configuration measures 490 × 245mm and uses 242 LEDs with a rated power of 28W per piece.

With CRI90 performance, 120° beam angle and dimmable operation, this flexible LED backlight sheet can be integrated into commercial displays, illuminated signs, furniture and architectural surfaces where consistent backlighting is required.

The product operates at DC24V and has a rated lifetime of up to 50,000 hours, making it suitable for long-term indoor commercial and decorative lighting applications. The current product information also specifies an IP20 rating, so it should be used in dry indoor environments unless a customized protected configuration is provided.

Design

The flexible sheet construction allows the LED backlight to be integrated into different lighting structures where a conventional rigid panel may not be suitable.

Its compact 490 × 245mm format can be arranged behind translucent materials to create illuminated surfaces for signage, displays, countertops and decorative applications.

The SMD2835 LED layout provides a wide 120° light distribution, helping spread illumination across the target backlighting area.

The product can also be customized for selected OEM and project applications, including dimensions, LED layout, color temperature and wiring configuration.

The original product page lists 242 LEDs, 28W power, 2800 lm luminous flux, 120° beam angle, 22.3 × 22.3mm cuttable length and IP20 protection.

Application

The flexible LED backlight sheet is suitable for indoor applications where a thin and adaptable backlighting source is required.

Typical applications include:

• Advertising lightboxes
• LED signage
• Retail display backlighting
• Display cabinets
• Countertop illumination
• Marble countertop backlighting
• Furniture backlighting
• Decorative panels
• Commercial displays
• Exhibition displays
• Architectural illuminated panels
• Customized lighting structures

For marble and countertop applications, the flexible LED sheet can be positioned behind suitable translucent materials to create an illuminated surface.

For advertising and signage projects, multiple sheets can be arranged to cover a larger illuminated area according to the required panel dimensions.

Size / Options

Standard configuration:

• Size: 490 × 245mm
• Power: 28W/pcs
• LED quantity: 242 LEDs
• LED type: SMD2835
• Voltage: DC24V
• Cutting length: 22.3 × 22.3mm

The current page lists 490 × 245mm as the product size and 242 LEDs as the LED quantity.

For OEM and project orders, USKYLED can discuss customized:

• Sheet dimensions
• LED quantity
• LED density
• LED layout
• Power
• Color temperature
• CRI
• Wiring
• Connectors
• Product labels
• Packaging

For large projects, buyers should provide the required illuminated area, available installation depth and target brightness so the appropriate configuration can be evaluated.

Lighting Options

The current product information lists several color temperature options, including:

• 2700K
• 3000K
• 4000K
• 6000K

The product attributes also indicate additional emitting-color possibilities and a wider listed color-temperature range. For commercial projects, the final available color and CCT should be confirmed with USKYLED before ordering.

CRI options listed on the product page include:

• CRI80
• CRI90
• CRI95

For retail displays, marble surfaces, product showcases and applications where color appearance is important, CRI90 or higher can be considered.

Installation

The flexible LED backlight sheet is designed for installation behind suitable translucent or light-diffusing surfaces.

Typical installation process:

1. Measure the required illuminated area.
2. Determine the required number of LED sheets.
3. Confirm the available installation depth.
4. Arrange the LED sheets evenly behind the illuminated material.
5. Connect the sheets to a suitable DC24V power supply.
6. Check polarity and electrical connections.
7. Test brightness and illumination uniformity.
8. Secure the LED sheets and provide suitable heat dissipation.

For large signage and lightbox installations, the LED sheets should be distributed according to the illuminated surface and power requirements rather than concentrated in a single area.

Because the standard product is IP20, it is primarily intended for dry indoor environments. Outdoor or wet-location projects should be discussed with USKYLED for an appropriate customized solution.
