Specifications
The LGP is a passive optical component. The dimensions below describe the PMMA plate; electrical values apply only to a separately selected LED system.
- Optical patterns matched to panel dimensions and LED entry edges.
- Custom outlines, openings, slots and fixing holes from approved drawings.
- For light boxes, retail fixtures, shelves, cabinets, signs and wayfinding displays.

Light-entry and control details
LED integration for the light guide plate
Short spans can be evaluated with one-edge input. Longer rectangular panels generally use two opposing edges, while large or near-square panels are reviewed for four-edge input and balanced thermal loading.
Optional lighting uses FH custom LED strips. Specify the required voltage, light color, brightness and control interface.

FAQ
Key details buyers usually confirm first.
What is supplied as an LGP component?
A bare LGP is a patterned PMMA light guide plate. LEDs, diffuser, reflector, wiring and power supply are included only when itemized in the quotation.
How does an LGP differ from a Frameless panel?
The LGP redirects light from an external LED source. A Frameless panel combines that plate with the face, edge lighting, backing and wiring as a finished illuminated assembly.
What limits apply to a custom LGP?
Custom sizes are reviewed against PMMA thickness, optical pattern, LED entry and handling requirements. The stated maximum size is not available for every combination; larger surfaces may need multiple panels.
What information is needed for a quote?
Send the plate dimensions, quantity, application, preferred PMMA thickness, LED entry edges and installation conditions. State whether you need the patterned plate only or a finished illuminated assembly; a drawing helps confirm cutouts and cable routes.
