Abstract
Disclosed herein are exterior architectural fixtures employing LED-based light sources that are capable of projecting light over long distances and providing a wide variety of lighting effects with high lumen output. These lighting fixtures have improved heat dissipation properties and are particularly suitable for large-scale façade washing and for illuminating large architectural structures, such as skyscrapers, casinos, and retail establishments, integrating efficient and compact power supply and control components for driving high-intensity LEDs to achieve a vast variety of lighting effects on a large scale.
