Patterned PMMA light guide panel developed by an LGP manufacturer

Buyer Resource / Manufacturer Selection

How to Choose an LGP & LED Light Guide Panel Manufacturer

A practical framework for importers, integrators, lightbox makers, and OEM buyers comparing optical capability, finished-panel integration, sampling, quality checks, and export supply.

Start with manufacturing scope

A reliable LGP supplier should control the optical path, not only cut a plastic sheet.

A custom light guide panel combines material selection, optical pattern density, LED entry, diffusion, reflection, thermal management, wiring, and mechanical support. Compare suppliers by how these decisions are reviewed together.

FH Lighting is the international brand of Shanghai Fanghao Bright Electronic Technology Co., Ltd. Its primary manufacturing focus is custom LGP and LED light guide panels developed and produced in Shanghai.

Manufacturer Comparison Checklist

Six capabilities to verify before comparing price.

A low unit price is not comparable when the optical pattern, LED system, diffuser, backing, wiring, inspection points, or packing scope is different.

CapabilityQuestions to askEvidence to request
Optical engineeringIs pattern density adjusted for the exact size, shape, and LED-entry direction?Drawing review, proposed entry layout, and an illuminated sample
Material processingWhich PMMA thickness and machining method fit the span, holes, curves, and edge detail?Material specification and dimensioned production drawing
LED integrationAre LED pitch, color, voltage, control, thermal path, and cable exit reviewed together?Electrical layout and agreed component specification
Finished assemblyCan the supplier provide the diffuser, reflector, backing, edge protection, wiring, and mounting detail?Layer structure, sample photographs, and approved bill of scope
Quality confirmationWhich dimensions, appearance, uniformity, color, and electrical functions are checked?Sample approval points and production inspection checklist
Export supplyWho coordinates labeling, modular protection, packing dimensions, documents, and replacement parts?Packing proposal and quotation defining the included supply scope

FH Lighting Reference Capability

Use published reference ranges to start the engineering conversation.

These are starting references, not a universal product promise. Final size, construction, output, power, lead time, and packing are confirmed from the drawing and approved sample.

01

PMMA Light Guide Plate

Optical-grade PMMA with 3-10 mm thickness options reviewed against panel span, structure, machining, and installation depth.

02

Ultra-Thin & Large Format

Finished formats up to 3000 × 2000 mm can be reviewed, subject to material, optical span, transport, and support requirements.

03

Optical Pattern Methods

Laser-dot, engraved-line, and screen-printed patterns are selected by geometry, visible finish, quantity, uniformity target, and budget.

04

LED Light Guide Panel

One-, two-, three-, or four-side LED entry with 2700K-6500K, tunable white, RGB, or RGBW options configured by project.

Four-Step Sourcing Process

Compare manufacturers using the same drawing and the same acceptance points.

01

Define the illuminated surface

Share dimensions, outline, application, installation space, viewing condition, quantity, and environmental exposure.

02

Review the proposed system

Confirm PMMA, optical method, LED entry, diffuser, reflector, voltage, control, cable exit, structure, and packing scope.

03

Approve a representative sample

Check dimensions, luminous uniformity, color, surface appearance, edge treatment, wiring, fit, and required control behavior.

04

Lock the production standard

Record the approved drawing, sample reference, inspection points, labeling, packing, schedule, and change-control process.

Use the LED Light Guide Panel Design Guide to prepare the technical brief before requesting quotations.

Choose the Required Supply Scope

Buy the optical component, the finished panel, or the complete lightbox system.

The correct supplier scope depends on what your own team already designs, sources, assembles, installs, and services.

Review LGP Options
01

Bare LGP Component

Patterned PMMA light guide plate for a buyer that integrates its own LEDs, diffuser, reflector, structure, and wiring.

02

Finished LED Light Guide Panel

Light guide plate, matched LEDs, optical layers, wiring, backing, and agreed edge treatment supplied as one assembly.

03

Complete Lightbox Kit

Lightbox structure, LGP, LED system, power supply, wiring, packing, and project documentation coordinated together.

04

Confidential Upstream Supply

Components or complete systems supplied to integrators, lightbox makers, distributors, importers, OEM, and ODM buyers without claiming their end-client relationship.

LGP Manufacturer FAQ

Questions importers and project buyers often ask first.

What is the difference between an LGP manufacturer and a general lightbox supplier?

An LGP manufacturer develops the optical plate, pattern density, light-entry path, and panel stack around the required luminous surface. A general lightbox supplier may focus mainly on the frame and graphic system or may source the optical component from another factory.

Is FH Lighting mainly an LGP manufacturer?

Yes. FH Lighting is the international brand of Shanghai Fanghao, whose primary category is custom LGP and LED light guide panel manufacturing. Advertising lightboxes and complete export kits are supporting solutions built around that core capability.

Can FH supply only the PMMA light guide plate?

Yes. A patterned PMMA LGP component can be supplied for customer integration, or FH can add matched LEDs, optical layers, wiring, backing, edge treatment, mounting details, and other agreed assembly items.

Can one supplier provide the LGP, LED system, power supply, and lightbox?

Yes. FH can quote a coordinated supply scope covering the lightbox structure, custom light guide panel, LED system, driver or power supply, wiring, packing, and project documentation.

How should buyers compare LGP quotations?

Compare the same drawing, material, thickness, optical method, LED entry, light color, voltage, control, diffuser, reflector, backing, wiring, inspection points, packing, and delivery scope. A unit price without these details is not a like-for-like comparison.

Can confidential chain-brand or commercial-property supply remain unnamed?

Yes. FH commonly works as an upstream manufacturer. Customer, end-client, brand, and project names remain confidential unless publication is authorized, and no direct end-brand relationship should be inferred.

What should an international buyer send for an initial review?

Send the illuminated size, outline drawing, quantity, application, light color, voltage or control preference, installation method, destination, environmental conditions, and any required packing or compliance documents.

How long does a custom LGP sample normally take?

Sample production normally takes 7-15 production days after the drawing and specification are confirmed. Courier or freight transit time is separate.
