LED Light Box

A light box earns its keep in dim rooms: backlit, the graphic reads from across the mall where a printed panel would go grey. Jin Yu manufactures SEG fabric light boxes, ultra-slim crystal (acrylic) light boxes, wall-mounted, hanging and pop-up models with even LED backlights.

The SEG system changed the economics of big faces. A printed textile carries a silicone strip on its edge; the strip pushes into a groove in the slim aluminium profile, and the fabric stretches drum-tight with no frame showing. Faces swap in minutes without tools - seasonal campaigns change in minutes, not hours.

Slim matters where space does. Crystal light boxes use an acrylic light-guide panel a few millimetres thick with LEDs along the edges - the poster sits millimetres behind the face, so the whole unit hangs on a wall like a framed picture. Deeper SEG boxes take backlit fabric for large seamless walls.

Every unit ships tested, LED boards and transformers fitted, graphics printed and installed if requested. Production runs under ISO 9001 in Foshan; buyers in 50+ countries order standard sizes or custom dimensions, single or double sided, with free samples of fabric printing for colour checks.
