    • A lamp (10) has a housing (12) with a base (14) with an internal circumferential wall (16) arranged about a longitudinal axis (18). A hollow body (20) projects from the housing (12) and is symmetrically arrayed about the longitudinal axis (18). A light guide (21) is positioned in the hollow body (20) and as a single output end (22) arrayed along the longitudinal axis (18) and has a plurality of radially extending arms (23), each of the arms having an input end (24). The light guide (21) is preferably constructed from a molded acrylic or a suitable glass having wave-guide characteristics.

    • An LED lamp (10) having a substantially concave heat sink (12) having a raised, frusto-conical center (14) surrounded by an outer rim (16). The heat sink (12) is preferably aluminum or other metal and at least the frusto-conical center preferably has a reflective coating. To further aid in heat removal the outer rim (16) can be provided with a plurality of apertures (16a). A side-emitting LED (18) is mounted on the frusto-conical center (14). A cover (26) is fixed to the outer surface (22) and defines a volume (28) between the frusto-conical center (14) and the cover (26). A circuit (30) is located within the volume (28) and an electrical connection (32) provides connection to the LED (18). In another embodiment a cover (26a) is provided with studs (54) and a reflector (42a) is provided with studs (56) that engage barbs (50) formed in a heat sink (12a).
    • 一种具有大致凹入的散热器(12)的LED灯(10),其具有由外缘(16)包围的凸起的截头圆锥形中心(14)。 散热器(12)优选为铝或其它金属,并且至少截头圆锥形中心优选具有反射涂层。 为了进一步帮助除热,外缘(16)可以设置有多个孔(16a)。 侧面发光LED(18)安装在截头圆锥形中心(14)上。 盖(26)固定在外表面(22)上并限定了截头圆锥形中心(14)和盖(26)之间的一个体积(28)。 电路(30)位于容积(28)内,电连接(32)提供与LED(18)的连接。 在另一个实施例中,盖(26a)设置有螺柱(54),并且反射器(42a)设置有接合形成在散热器(12a)中的倒钩(50)的螺柱(56)。
