Fiber Optic Showcases

Glass and acrylic cases trap heat. Even efficient LED boards generate thermal loads that warp documents and degrade humidity control. Fiber optic systems place the LED illuminator in a remote, ventilated cabinet. Glass or plastic fibers carry only the visible light spectrum into the sealed display case.

System Architecture

The system comprises three components: the illuminator, the harness, and the fittings.

• Illuminator: Houses the LED engine, heat sink, driver, and optics. Usually mounted under the floor or behind a wall.
• Harness: Bundled PMMA (plastic) or glass fibers. Glass transmits better over long distances (10m+). PMMA bends tighter.
• Fittings: Miniature lenses attached to fiber ends inside the case. Diameters range from 5mm to 12mm.

Micro-Articulation

Displaying jewelry or coins requires multiple angles. Fiber ends attach to articulated magnetic wands or miniature gimbals. They focus sharp micro-beams onto facets. The light contains absolutely zero IR or UV. The case interior remains thermally stable.

Pros and Cons

Pros: Zero heat in the display. Zero electrical hazard in the case. Absolute UV/IR block. Miniature footprint. Maintenance (driver replacement) happens outside the secure vitrine.

Cons: Extremely high cost. Complex routing during case fabrication. Harness length limits output (light attenuates over distance). Fixed color temperature dictated by the central illuminator.

Integration happens in the factory. Case manufacturers route fibers through structural channels before glass goes on. Retrofitting fiber optics into existing cases is messy and rarely successful.
