Wide Angle LED Backlight Sheet with Lens 480x240mm (#6105)
24V · 50 LEDs
Model: 6105
Description
The #6105 wide angle LED backlight sheet pairs 2835 LEDs with a wide-beam lens on a 3oz copper FPCB: 480x240mm, 24V DC, 50 LEDs, 12-60W, cut on a 48x48mm grid, 160 degree beam. The lens does the same job as on the 12V version - it widens each emitter so a shallow lightbox can be lit evenly with very few LEDs - while 24V halves the current for the same power, which means less voltage drop and more sheets on a single feed across a large sign. The heavy 3oz copper adds thermal headroom and keeps brightness consistent from the first sheet to the last in a run. Colour temperature is selectable from 1800K to 6500K, so the backlight can be matched to the printed fabric or film rather than shifting its colours. Typical applications are advertising lightboxes, SEG fabric frames, menu boards, poster frames and retail signage. IP20 standard, dimmable, up to 4 sheets per single-end feed and 8 with dual-end input.

Wide Angle Lens LED Backlight Sheet — Buyer Questions
How does a lens LED sheet light a shallow lightbox evenly?
The integrated lens spreads each LED across 160–170°, so neighbouring beams overlap only a short distance above the board. Fifty lensed LEDs cover the same 480×240 mm as hundreds of bare emitters, which keeps an SEG fabric frame or slim poster box even from roughly 40–60 mm of depth at a much lower load.

Should I use a 12 V or 24 V lightbox LED sheet?
12 V (#6710) suits vehicle interiors, display cases and sites with an existing 12 V supply. 24 V (#6105) is the default for large signs: half the current means less voltage drop, more sheets per feed and thinner conductors across a wide cabinet.
How many LED sheets cover one square metre of lightbox?
Each sheet lights 480 × 240 mm, so roughly nine sheets tile one square metre. Cut on the 48 × 48 mm grid to square the last row to the frame, and plan feed points so no chain exceeds four sheets from one end.

Which colour temperature suits printed fabric graphics?
4000–6500 K keeps printed colour neutral; 1800–3000 K warms the whole image. The #6105 is selectable across 1800–6500 K, so the backlight can be matched to the print instead of shifting it, and 3 oz copper keeps brightness consistent from the first sheet to the last.
Tested lightbox depth, cutting precision and efficacy — all 10 LED sheets compared
Three numbers decide whether an LED sheet works in your cabinet: the diffuser depth it needs before the dots disappear, the smallest piece you can cut without losing a channel, and the load it puts on the driver. The table below lists all ten DENO FlexLite sheets against those three measured figures so a shallow stone lightbox, an irregular logo or a low-load SEG frame can be specified in one pass.

- Diffuser depth is the air gap measured between the LED sheet and opal acrylic in our lightbox rig; a translucent stone slab counts its own thickness towards that gap.
- Cutting precision is the smallest complete unit that keeps every colour channel intact — always cut on the printed line so the reconnection pads survive.
- Plan four sheets from a single-end feed and eight with dual-end input, then size the driver at the sheet's maximum wattage plus 30 % headroom.
