W-DMX on Bangkok’s Rama VIII Bridge

W-DMX on Bangkok’s Rama VIII Bridge

W-DMX by Wireless Solution recently played a starring role for one of Thailand’s most visual celebrations – the King’s Birthday. To celebrate, Bangkok created a month-long display of decorative lighting along the banks of the Chao Phraya River and along the Rama VIII Bridge. Time Code Light Sound of Bangkok worked with Wireless Solution to achieve the lighting on one of the most prominent displays.

Thai people and tourists flocked to Bangkok to admire the beautiful light show this year, focused on seven parts along Chao Phraya River entitled “The Spectacular Light Show: The Royal Kingdom” with different and unique lighting displays.  The Rama VIII Bridge was named “The Capital of Light”.

For the bridge, which was the grandest of the seven displays, this beautiful landmark was awash with light. The Rama VIII Bridge is a cable-stayed bridge crossing the Chao Phraya River in Bangkok, Thailand. The bridge has an asymmetrical design, with a single pylon in an inverted Y shape located on the western bank of the river. The bridge has a main span of 300 metres (980 ft), and was one of the world's largest asymmetrical cable-stayed bridges at the time of its completion.

The final system was designed with four DMX universes of wireless lighting control including fixtures, light 5W Laser, 21 searchlight beams, moving heads and 18 wall washer fixtures including many ACL Par 64 fixtures. 

W-DMX equipment consisted of twos W-DMX WhiteBox F-2 (2048-Channels), 16 W-DMX WhiteBox R-512, 19 W-DMX 8 dBi directional antennas, one W-DMX 8dBi omnidirectional antenna and 20 3m antenna cables. A detailed diagram was supplied, showing all equipment and fixture locations clearly marked.

Time Code Light Sound explained: “For our part, we were to support the lighting design for three of these places, the Rama VII, bridge, Sarnti Chaiprakarn, and Wat Arun (Arunratchwararam temple). The proudest being the Rama VIII bridge. It’s kind a big project for lighting on bridge. We used W-DMX system in this show and this absolutely worked and was very useful for us because we don't need to use long DMX signal cable and our controller wasn't on the bridge, but our board controller was located near area. We received support from Wireless Solution Sweden AB. They gave us the best suggestion for this event. I'm very appreciative for this service.

“We spent about five days for set up and rehearsal. We never met any problem with the DMX signal. The WhiteBox DMX units were set to this place for 33 days. They were in the heavy rain and hot weather in Thailand. They're still durable even now.”
