迪拜第6大桥SRBS Crossing (6th Crossing)照明设计

This bridge connects Bur Dubai to Deira. At 201 meter height, it is the largest single arch span bridge in the world. This bridge is being built at the cost of 4 billion dirhams, and will be a significant feat of engineering internationally. The concept for the lighting of the Dubai Sixth Crossing Bridge is derived from the significance that Islam places on the tradition of the sighting of the crescent moon as a basis for measuring time, and on the Lunar Cycle. The alternate accumulation and waning of the intensity of light reflected from the bridge arch surface are synchronized with the levels of light reflected by the moon at each phase, and so the intensity of light on the bridge arch serves as the measurement of the portion of the moon that is reflecting light at any given phase of the lunar cycle. Reflections of the illuminated arch in the water beneath the bridge “complete the circle” of the full moon’s profile.

       The bridge is 200m tall, 1.235km long & 86m wide.It has 6 lanes of traffic in each direction & 2 track lines.The design goal is to create the biggest “Moon-Dial” in the world. Our challenge was to establish a system for controlling the change of light levels throughout the 29.5-day lunar cycle. Gradations of light would have to be achieved by way of a complex switching system involving multiple layers of light. In mirroring the lunar cycle, we developed a separate lighting scene for each phase of the moon’s illumination, including the full, gibbous, half, crescent, and new moons. In our scheme, the new phase is not represented by complete darkness, but instead emits a subtle glow suggestive of the dim light that is reflected by the moon during a total lunar eclipse. For two days observers will see this glow, which results from gentle reflection of the light used to illuminate the bridge cables. The lighting of the bridge arch returns with the appearance of the crescent moon, significant to the identification of the waxing crescent, which is the most significant phase of the moon for Islam. After this point, the arch light alternately accumulates and dissipates in sync with the rest of the moon’s phases.
