    • The invention provides systems and methods for providing illumination. A lighting unit may have a support structure, and one or more light emitting elements supported by a circuit board contacting the support structure. A first optical element and a second optical element may be provided. A remote luminescent material may be provided on one or more optical elements. Light emitting elements configured to excite the luminescent material such as highly efficient light emitting diodes may be directed towards the luminescent material. The support structure may be a heat dissipating element, which may conduct heat from a heat source to a surface of the support structure. The heat dissipating element may have a passageway permitting the formation of a convection path to dissipate heat from the support structure. Such lighting units may be used to replace conventional fluorescent light tubes or other lighting devices, or may be provided as standalone lighting units.
    • 本发明提供了用于提供照明的系统和方法。 照明单元可以具有支撑结构,并且一个或多个由电路板支撑的发光元件与支撑结构接触。 可以提供第一光学元件和第二光学元件。 远程发光材料可以设置在一个或多个光学元件上。 配置成激发发光材料(例如高效发光二极管)的发光元件可以被引向发光材料。 支撑结构可以是散热元件,其可以将热量从热源传导到支撑结构的表面。 散热元件可以具有允许形成对流路径以从支撑结构散发热量的通道。 这种照明单元可以用于替代常规的荧光灯管或其他照明装置,或者可以被提供为独立照明装置。
