Light is directed laterally into a plastic plate from the edge by LEDs. The structuring of the plate results in the targeted refraction of light. It achieves a homogeneous surface appearance and at the same time an efficient conversion into light, which is emitted across the entire surface. This concept enables wide-area lighting solutions with low energy usage in extremely flat construction. As a result, it can be applied in areas with limited space, where new design aspects are being promoted or where there is a requirement for absolutely homogeneous surfaces in combination with high efficiency.
The areas of application are varied:
- General lighting, e.g. for flat pendant luminaires, recessed ceiling lights or wall lamps
- Emergency lighting
- Automotive interior lighting
- Backlighting of components/switches/displays, e.g. in building communication equipment
- Display backlighting
Polyscale has mastered the balancing act between surface homogeneity, high system efficiency and extremely low substrate thickness. Standard applications have a substrate thickness of 3 - 4 total mm. Thicknesses of 0.5 mm can be achieved for special applications. Because each workpiece is individually processed by laser, it is possible to produce prototypes and small quantities, as well as small and large production runs. Polyscale develops the appropriate structure for each application. This creates the economic conditions and the technical lighting properties for an optimum solution. Current developments should allow even thinner substrates in the form of foil or curved or freely shaped shining surfaces.
