    • A solid-state lamp comprises a body having a first chamber with inlet apertures and a second chamber with outlet apertures. The chambers are interconnected in fluid communication by one or more passages. The lamp further comprises a thermally conductive substrate having a heat radiating surface located within at least one chamber and one or more solid-state light emitters, typically LEDs, mounted in thermal communication with the thermally conductive substrate. The lamp is configured such that in operation heat generated by the LEDs is radiated by the substrate into one or both chambers causing a difference in air pressure between the chambers that results in surrounding air being drawn into the inlet apertures, flowing through the chambers via the interconnecting passages in the substrate and exiting through the outlet apertures thereby cooling the substrate and LEDs.
    • 固态灯包括具有带有入口孔的第一室的主体和具有出口孔的第二室。 腔室通过一个或多个通道流体连通地相互连接。 该灯还包括导热基底,其具有位于至少一个腔室内的散热表面和一个或多个固体发光体,通常为LED,其安装成与导热基底热连通。 灯被配置为使得在操作中,由LED产生的热量被衬底辐射到一个或两个室中,导致室之间的空气压力差,导致周围的空气被吸入到入口孔中,经由腔 在衬底中连接通道并通过出口孔离开,从而冷却衬底和LED。
