The development of museum lighting technology has gone through an evolution from traditional light sources to modern intelligent lighting, with its core goal always revolving around the dual mission of exhibit protection and artistic presentation. The following are key development milestones and technological features:

1. Historical evolution

From ancient times to the 19th century: Domestic and foreign museums mainly relied on natural light or simple lighting such as torches and oil lamps, such as pottery beans and bronze lamps from the Warring States period in China

After the 18th century, Europe gradually introduced gas lighting

20th century technological innovation: incandescent and fluorescent lamps were widely used, but gradually phased out due to issues such as UV damage to exhibits

LED technology has become mainstream in the 21st century, with advantages such as low ultraviolet infrared radiation and high color rendering

2. Characteristics of Modern Technology

Protective design: using low UV LED lighting fixtures, precise control of illumination and color temperature (such as 2700K-5700K adjustable), reducing the risk of cultural relics fading

Artistic expression: Highlighting the hierarchy of exhibits through key lighting and balanced atmosphere. For example, oil paintings require soft focus, while paper-based works require low light intensity

Intelligent management: supports zone dimming and timing control, automatically dims when no one is visiting to reduce exposure time

Introduction to the comparison between led downlight  and spotlights

1、 Definition and Core Features

led downlight

Embedded ceiling lighting fixtures, projecting light vertically downwards to maintain uniformity in building decoration

The angle of the light source cannot be adjusted, the beam angle is ≥ 50 °, and the light is evenly dispersed

Suitable for basic lighting (such as living rooms, corridors, kitchens)

led Spotlight

Concentrated lighting fixtures with adjustable light direction and optional beam angle of 15 ° -60 °

Directional lighting is achieved through lenses/reflective cups to highlight decorations or create an atmosphere

Suitable for key lighting (such as background walls, art displays)
