    • Disclosed is an LED lighting system with improved airflow and heat dissipation qualities. In one embodiment, the system comprises a heatsink mounted to an LED chip, and a fan assembly blowing air into the heatsink. The fan assembly includes a plurality of fans, the wind tunnels of the plurality of fans providing greater airflow in the center of the heatsink than a conventional one-fan configuration. In a further aspect, the disclosed system comprises a light head assembly in which cool air enters the light head assembly via the bottom and rear, and hot air is drawn out of the top of the light head assembly. An airflow path is created by selectively placing fans, baffles, walls, and openings in the lighting assembly.
    • 公开了具有改善的气流和散热特性的LED照明系统。 在一个实施例中,系统包括安装到LED芯片的散热器和将空气吹入散热器的风扇组件。 风扇组件包括多个风扇,多个风扇的风洞在散热器的中心提供比常规单风扇配置更大的气流。 在另一方面,所公开的系统包括光头组件,其中冷空气经由底部和后部进入光头组件,并且热空气从光头组件的顶部被拉出。 通过选择性地将风扇,挡板,墙壁和开口放置在照明组件中来创建气流路径。
