布拉格天文馆以独特LED技术迈入新时代
Prague Planetarium enters a new era with unique LED technology  

布拉格天文馆近期完成了一项重大现代化改造，这不仅仅是更换投影设备那么简单。由建筑师雅罗斯拉夫·弗拉格纳（Jaroslav Frágner）在20世纪50年代设计的受保护建筑，在此次翻新过程中需移除近几十年来的多次改造痕迹，以便安装革命性的LED投影技术。

The Prague Planetarium has undergone a major modernization that goes far beyond just replacing its projection equipment. The renovation of the protected building, designed by architect Jaroslav Frágner in the 1950s, was complex. It required removing layers of interventions from recent decades to make way for the installation of revolutionary LED projection technology.

全球最大LED穹幕
The largest LED screen of its kind in the world

此次项目的核心是一块由美国公司COSM提供的新型半球形屏幕，直径达22米，拥有令人惊叹的4500万像素。这种尺寸与品质兼具的屏幕在全球范围内独一无二。得益于此，观众可以沉浸于极具色彩深度与真实感的空间幻象之中，获得前所未有的沉浸式体验。

At the heart of the project is a new hemispherical screen from the American company COSM, 22 meters in diameter, with an incredible 45 million pixels. Such a screen of this size and quality does not exist anywhere else in the world. Thanks to it, visitors can experience an immersive spatial illusion with extraordinary color depth and realism.

全新观众厅与定制座椅
New auditorium and custom seats 

经文物保护机构同意，原位于主厅中央的蔡司耶拿投影仪被迁出，为全新的观众厅设计腾出了空间。collcoll建筑事务所的建筑师设计出阶梯式几何布局，视觉上让观众仿佛升至地平线之上。座位总数增加了20%，达到277个，同时空间布局确保了观众可舒适、安全地流动。

The central Zeiss Jena projector was moved outside the main hall by agreement with heritage conservators, freeing space for a new auditorium design. Architects from the collcoll studio designed a stepped geometric layout that visually lifts the audience above the horizon. Capacity increased by 20% to 277 seats, with spatial arrangement supporting comfortable and safe movement.

座椅由捷克制造商专门定制设计——可调节、符合人体工学，兼具舒适性，确保观众保持专注。投影穹顶后方隐藏的声学处理装置进一步增强了无限空间的幻觉感。

The seats were custom-designed with a Czech manufacturer—they are adjustable, ergonomic, and comfortable enough to keep visitors attentive. Acoustic treatment hidden behind the projection dome further enhances the illusion of infinite space.

面向未来的能源解决方案，融合历史建筑结构
Future-oriented energy solutions integrated into the historic framework  

新技术的安装需要配备新的能源与技术设施，这些系统在最大程度尊重受保护建筑结构的前提下被整合入内。制冷与热回收系统的设计充分考虑了天文馆位于斯特罗莫夫卡公园核心区域的地理位置——夏季屏幕散发的热量通过六口200米深的地热井储存，冬季再用于加热建筑。穹顶本身的热功率相当于三栋家庭住宅，而这些热量也被有效循环利用。

The installation of new technology required new energy and technical facilities, integrated into the building with maximum respect for its protected structures. Cooling and heat recovery were designed considering the planetarium’s location in the heart of Stromovka park—heat from the screen is stored in six deep wells (each 200 m deep) in summer and used to heat the building in winter. The dome itself has a thermal output comparable to three family houses, so the heat is reused within the building.

其他空间焕新升级
A new look for other spaces as well  

本次改造还涉及前厅与配套设施。入口处原有的展览被一块圆形LED屏幕所替代，为展示内容提供了更多可能。新设计的衣帽间实现了来客与离场人流的分隔，提升整体舒适度。地下层将于夏季开放全新的模拟体验展区；户外景观完成后，出口处还将设立商店。同时，毗邻的玫瑰园中一处位置不当的坡道也将被拆除，便于经由商店实现更顺畅的无障碍通行。

The renovation also affected the foyer and facilities. The original exhibition at the entrance was replaced by a circular LED screen serving as an additional presentation surface. A newly designed cloakroom separates incoming and outgoing visitor flows, increasing comfort. Over the summer, a new simulator exhibition in the basement will open, and after completing outdoor landscaping, a shop will be established at the new exit. An inappropriately placed ramp will be removed from the adjacent rosarium, simplifying barrier-free access through the shop.

此次现代化升级，使布拉格天文馆凭借独一无二的LED穹幕技术，跃升为全球沉浸式教育与文化领域的引领者，为观众呈现前所未有的宇宙视觉体验。

This modernization positions the Prague Planetarium as a world leader in immersive education and culture with its unique LED dome technology, offering visitors an unprecedented visual experience of the cosmos.
