The Symphony of Light is the largest permanent Light & Sound Show in the world, and was awarded an entry into the Guinness Book of World Records in 2005. It is an ever-improving system using the latest technologies and covers almost the entire skyline of the famous Victoria Harbour of Hong Kong.

The Hong Kong Coliseum is part of the Hong Kong Light Show, and is to be lit with the latest LED Technology. The proposed system, should not only be completely programmable using DMX controllers but also bright enough to be viewed from across the harbor and the Peak in Hong Kong. The limited installation space available was a particular challenge, to achieve the desired effects.

The lighting solution was to be created so as to provide a uniform luminance level of 20 cd/m² (uniformity specified) and at the same time, ensure that the system is completely programmable using DMX 512 controller systems.

Hence, a special LED Strip Light solution, incorporating stringent material specifications, in terms of the LED luminaires and LEDs by themselves was developed and used.

The installation of this system was also a concern. The Luminaires were located at the base of the inverted pyramid shaped façade, with a maximum distance of 500mm from the façade.

The entire system used specially developed narrow beam collimating lens, which provided the necessary narrow beam to light up the 18 meter height façade. A set of four luminaires (each with 16 red, blue & green LEDs) were used to light up the façade. Continuous rows of luminaires were located all along the façade and gaps in the installation were filled up with shorter versions of the luminaire.

The top part of the façade was also lit up using a single row of LED Strip Light Luminaires, to ensure even and uniform lighting effect. The corners of the façade posed a specific challenge, of being able to light up the façade evenly. For this purpose a combination of Narrow and Wide beam Luminaires were used. Also the Luminaires were provided with a specially designed secondary optics covers, which ensured that the light distribution on the façade was as even as the rest of the façade.

The Luminaires were located on the parapet wall, so as to ensure better light distribution.

The entire system proposed was DMX 512 compatible, which allowed for programming of the Strip Light Luminaires and synchronization with the Symphony of Light show System.

Apart from allowing for a possibility to create 16.7 million colours using these luminaires, each luminaire was provided with 2 separate addresses for 2 sections, so as increase the clarity of lighting installation and provide for greater flexibility during programming. The Luminaires and control systems provided by Philips, ensured that the system has a capability, that the Light installation, can be synchronized with music, if desired.

The installation was programmed to be part of the Symphony of Light Show (which operates every day) in Hong Kong.
