Changsha Jingtian Plaza Twin-Tower Facade Lighting Project
At Changsha Jingtian Plaza, vertical LED pixel lines follow the curtain-wall fins of two super high-rise towers. Graphics near the crowns and linear lighting along the podium give the development two distinct lighting scales, from the skyline to the street.
Jingtian Plaza rises above Changsha’s commercial district as two slender towers joined by a lower podium. From nearby intersections, long light lines express the towers’ height, while larger imagery near the crowns creates a distinct focal area. The glass elevations remain largely dark, so the illuminated elements are easy to read against the night sky.
CRANE supplied and customized luminaires for the project. Its original case record places LED pixel lights on curtain-wall fins and linear lights along the podium. Those locations have different engineering requirements: the tower system must remain legible at long range, while the podium is experienced at pedestrian distance, where source visibility and mounting details matter more.

Integrate Vertical LED Pixels with Curtain-Wall Fins
The pixel runs extend across many floors. Even small spacing or alignment errors become noticeable when viewed from the street. On a comparable tower, fixture positions should follow the actual fin layout, with transitions across facade joints and setback levels planned in advance. Power and signal routing, weatherproof connections and safe replacement access belong in the curtain-wall detail.
Make Crown Graphics Legible at a Distance
The photographs show larger images and color fields near the tower crowns, set above finer vertical lighting. These are different visual tasks. Content for a high-rise crown should be tested against the physical pixel grid, expected viewing distance and oblique street views. The number of pixels alone does not guarantee a readable image; content scale and contrast are equally important.
Separate Podium Lighting from Daily and Festival Scenes
The archived specification lists two 12 W linear-light options: RGBW with DMX512 control, and 3000 K with switch control. The same case describes warm-white and cool-blue lighting for regular evenings, with DMX512 pixel animation for festivals. This distinction matters when specifying a similar development: the podium’s close-range lighting should be planned independently of media scenes high above the street.

Jingtian Plaza Twin-Tower Lighting Photos & Film
The night photographs record several crown images above the same vertical light lines. The 42-second portrait project film provides a closer look at the tower surfaces from street level.

Vertical Lines Beneath Changing Crown Imagery
At nearby intersections the two towers are perceived as one composition. Crown brightness, vertical-line continuity and the surrounding street lighting all influence visual balance. These are useful reference views for testing media content before a similar project is commissioned.

Vertical pixel lines on curtain-wall fins
YY Round pixel lights are a current catalogue option for repeated point-source lines on tower facades. For a similar installation, set the spacing to suit the curtain-wall grid and principal viewing distances, then confirm the required light color, control mode and weatherproof connections. Crown graphics still need a separate content-mapping study.
The 24 W XC Curtain-Wall profile is a catalogue option for continuous straight lighting along podium or facade details. Review the available fixing channel, line joints, cable access and source visibility from the sidewalk. Its 24 W catalogue specification should not be confused with the 12 W linear-light configurations recorded for the original project.
Practical questions on pixel spacing, tower-crown graphics, control modes and high-rise installation.
How are LED pixel lights integrated into a high-rise curtain wall?
Mounting positions are coordinated with curtain-wall fins or mullions rather than laid out independently of the facade. Check the physical fixing detail, weatherproof wiring, facade movement and maintenance access. A representative test bay can verify the spacing and appearance before a full-tower installation.
What makes tower-crown graphics readable from the street?
Pixel pitch, viewing distance, image contrast and the tower’s physical geometry all affect legibility. Content that looks clear on a computer screen may lose detail when distributed across widely spaced facade pixels. Test representative graphics from the actual public viewpoints before confirming resolution.
Which lighting and control modes are documented at Jingtian Plaza?
CRANE’s case record describes warm-white and cool-blue lighting for regular evenings and DMX512-controlled pixel animation for festival scenes. Its linear-light table separately lists a 12 W RGBW/DMX512 configuration and a 12 W, 3000 K switch-controlled configuration. The published data does not define the entire controller network.
Why should podium lighting be specified separately from tower lighting?
Tower pixels are viewed across long distances and need consistent patterns. Podium fixtures are much closer to pedestrians, so glare, shielding, uniformity and maintenance access become more important. Their operating schedules and control requirements may also differ from the media facade above.
What details are needed to quote a twin-tower facade lighting system?
Provide tower elevations, curtain-wall fin spacing, crown display areas and podium sections. Add the main viewing distances, power and signal routes, access for facade maintenance and the expected daily and event lighting scenes. These details allow fixture quantities, addressing and custom mounting requirements to be assessed.
