24/7 lighting intelligence for enhanced viewing and preservation of priceless artifacts

The National Palace Museum in Taipei, renowned for its collection of ancient Chinese paintings and calligraphy, faced a unique challenge—providing ideal lighting for highly light-sensitive artifacts. In 2023, the museum launched a lighting upgrade project for its calligraphy gallery. Partnering with Delta Electronics, the museum adopted full-spectrum LED luminaires combined with the BIC (Bluetooth Intelligent Control) smart lighting system. This solution not only ensured high-quality illumination and color rendering but also introduced 24/7 monitoring of color temperature, illuminance, and environmental conditions. By integrating smart control and real-time sensing, the museum achieved a groundbreaking balance between preservation and modern display, setting a new global standard in museum lighting.

Precision Lighting Meets Preservation

Ancient scrolls and paintings are extremely vulnerable to excessive light exposure. Previously, the museum used metal halide lamps that offered poor lifespan, uneven lighting, and no environmental monitoring. Scrolls displayed vertically at close viewing distances often suffered from hotspots and shadows, distorting the visual experience and threatening the integrity of the artifacts. The museum required a lighting solution that could deliver high optical performance, maintain uniform brightness, and adapt to complex display conditions—while simultaneously enabling continuous environmental oversight to protect its treasured exhibits.

Full-Spectrum LEDs with BIC Smart Control

Delta delivered a custom solution using full-spectrum linear polarized LED luminaires, designed to provide near-daylight color rendering and even illumination for vertical artworks. The system’s asymmetric optics and dual-direction lighting eliminated shadowing and glare. Integrated with Delta’s BIC smart lighting platform, the solution included Bluetooth-enabled sensors and a cloud-based management dashboard. It enabled 24/7 monitoring of illuminance, color temperature, and ambient temperature/humidity. When light sources age or spectral shifts occur, alerts are triggered to prevent blue light overexposure. The platform also allows scheduling and adaptive control based on exhibit needs—bringing precision, intelligence, and flexibility to museum lighting management.

Pioneering a Smarter Museum Future

The upgraded lighting system delivered dramatically improved visual clarity and artifact protection. Experts praised the enhanced color accuracy and uniformity. With automated real-time monitoring, the curatorial team now operates with greater confidence and reduced manual effort. The National Palace Museum became the first in the world to deploy a fully integrated IoT-based lighting solution, establishing itself as a leader in museum innovation. Delta’s BIC system not only optimized the visitor experience but also laid the foundation for a sustainable, intelligent approach to heritage preservation—blending tradition with cutting-edge technology for future generations.
