Lighting accounts for approximately 20% of global building electricity consumption and about 11% of the electricity usage in an average Canadian home. The deployment of high-efficiency alternating current (AC)-based light-emitting diode (LED) lighting in newly constructed homes has recently gained traction, enabling a reduction in residential energy consumption in comparison to homes utilizing traditional AC-based incandescent lighting. However, LED lighting technology is inherently direct current (DC) powered. Existing AC-based LED devices convert the incoming AC power to low-voltage DC power, which incurs electrical losses and also leads to increased complexity and reduced reliability of the overall lighting system.

照明约占全球建筑用电量的20%，约占加拿大普通家庭用电量的11%。最近，在新建住宅中部署基于高效率交流（AC）的发光二极管（LED）照明已经获得了牵引力，与利用传统的基于AC的白炽灯照明的住宅相比，能够减少住宅能耗。然而，LED照明技术本质上是直流（DC）供电的。现有的基于AC的LED设备将输入的AC功率转换为低压DC功率，这引起电损耗并且还导致整个照明系统的复杂性增加和可靠性降低。
