    • An engine and associated methods are disclosed. An engine in accordance with the present invention comprises a housing defining a cavity and a slidable member disposed in the cavity. The slidable member is preferably configured to form one or more combustion chambers, and the slidable member adapted to slide back and fourth relative to the housing in a cycle. One or more intake ports are provided for selectively providing fuel to the one or more combustion chambers during selected timed during the cycle. One or more exhaust ports are provided for selectively venting exhaust from the one or more combustion chambers during selected times during the cycle. The intake and exhaust ports are preferably disposed so that intake and exhaust flows are in the same direction (e.g. uniflow).

    • A more efficient solid-state light emitting device in which phosphors excited by radiation produce visible light. The efficiency is increased by, for example, providing a reflector adjacent to the phosphor layer for reflecting at least some of the radiation that passes through the phosphor, back into the phosphor. The reflector may also reflect at least some of the visible light that is emitted by the phosphor toward a designated light output. Alternatively, or in addition to, the lateral edges of the active region of the radiation source can be at least partially surrounded by a visible light emitting phosphor and a reflector. This allows more of the radiation to interact, and thus excite, the phosphor material, making the device more efficient. The reflector also may reduce optical and radiation cross talk between adjacent light emitting devices.
    • 一种更有效的固态发光器件,其中通过辐射激发的荧光体产生可见光。 通过例如提供与荧光体层相邻的反射器来提高效率,用于将穿过荧光体的至少一些辐射反射回磷光体。 反射器还可以将由磷光体发射的至少一些可见光反射到指定的光输出。 或者,或除了辐射源的有源区域的横向边缘可以至少部分地被可见光发射磷光体和反射器包围。 这允许更多的辐射相互作用并因此激发磷光体材料,使得器件更有效率。 反射器还可以减少相邻发光器件之间的光学和辐射串扰。
