''Sparkling lighting'' on
Makkah Royal Clock Tower 
Illumination - Royal Clock Tower - Makkah - Saudi Arabia Year of manufacture: 2011
Architect: SL RASCH
The project by AE&T Lighting The highest we have made!
We have participated in this project "Royal" by the German architect SL Rasch who signed several projects in the Middle East.
Project challenge To visually announce Prayer Time to the whole Makkah city by illuminating the top of the Makkah Clock Tower (601 m high). The flashers should be visible in the daytime as well as at nighttime.
From its 601 meters, the tower offers real estate, commercial and luxury resort. It is especially noted for its clock 40 meters in diameter, visible more than 20 km on 4 sides, and surmounted by a 170 meters spire.
It is precisely for this flickering arrow we need to design a specific flash and system programming. The flickering should sound to indicate the time of daily prayers or the beginning of Ramadan.
Three major constraints are overcome: the extreme heat and constant wind gusts at this height, the combination of two technologies and two colors in a single device without risk of overheating, and prohibited non-Muslim presence on the floor of the Mecca.
AE&T Lighting Solution We designed a special “double technology” flasher, with powerful Xenon and green LEDs. The flashers are designed to operate in ambient temperatures of up to 70°C. The products can be installed and maintained from the inside of the building.
To withstand the hot and heavily exposed to sunlight environment, the choice of material used for making the case has focused on a polycarbonate ultra UV resistant and anti yellowing.
For the electronic part, our Design Office has developed a system that combines proven technology Xenon and LED technology. The Xenon lamp triggers a powerful white flash, while the LEDs produce a beautiful green sheen, color desired by the architect.
With our exclusive programming, combining the two technologies allows a multitude of lighting effects. To approximate atmospheric conditions Mecca, equipment and lighting effects have been tested and validated to Dubai before final installation on the monument.
In order to understand the system without being present on the site, we have dispatched a team of Tunisian engineers previously trained in our systems and our products.
