    • A lamp (40) includes a linearly extending heat sink (12), blue-light-emitting LEDs (14) mounted on the heat sink (12), and a light emitting cover mounted on the heat sink (12) in line with the LEDs (14), a first portion (44) of the cover opposite the LEDs (14) including a phosphor (20) that is excited by the LEDs (14) to emit white light. The cover may be a tube (49) with the LEDs (14) outside the tube, a portion of the tube (41) nearest the LEDs (14) being transparent and receiving light from the LEDs (14). The tube (42) may include reflectors (48) that are attached to an exterior surface of the tube (42) to hold the tube on the heat sink (42). Alternatively, the cover may enclose the LEDs (14) on the heat sink (12), where a portion of the cover has an interior surface that reflects light from the LEDs (14) to the first portion. The lamp (40) may include electrical connections that allow for multiple lamps to be connected in series.
    • 灯(40)包括线性延伸的散热器(12),安装在散热器(12)上的蓝光发射LED(14)以及安装在散热器(12)上的发光盖,与 LED(14),与LED(14)相对的盖的第一部分(44),其包括由LED(14)激发以发射白光的磷光体(20)。 盖可以是具有LED(14)在管外部的管(49),最靠近LED(14)的管(41)的一部分是透明的并且接收来自LED(14)的光。 管(42)可以包括附接到管(42)的外表面以将管保持在散热器(42)上的反射器(48)。 或者,盖可将LED(14)封装在散热器(12)上,其中盖的一部分具有将来自LED(14)的光反射到第一部分的内表面。 灯(40)可以包括允许多个灯串联连接的电连接。
