    • A lamp (6) includes a housing (5) mounted to a lamp post (4) and a light-emitting diode module (10) mounted in the housing (5). The light-emitting diode module (10) includes a metal substrate (21) and a plurality of light-emitting diode dies (221) mounted on a face (211) of the metal substrate (21). A jacket (11) has a coupling surface (112) engaged with the other face (212) of the metal substrate (21). A heat conduction pipe (12) includes a portion (123) received in a longitudinal hole (111) of the jacket (11). The coupling surface (112) of the jacket (11) has an opening (114) in communication with the longitudinal hole (111). A portion of an outer periphery (124) of the portion (123) of the heat conduction pipe (12) is in direct, thermal contact with the other face (212) of the metal substrate (21) through the opening (114) of the jacket (11) to absorb heat generated by the light-emitting diode dies (221). A finned heat sink (13) is mounted on another portion (121) of the heat conduction pipe (12) outside the jacket (11) to dissipate heat transferred to the heat conduction pipe (12) into the environment.
    • 灯(6)包括安装到灯柱(4)上的壳体(5)和安装在壳体(5)中的发光二极管模块(10)。 发光二极管模块(10)包括金属基板(21)和安装在金属基板(21)的面(211)上的多个发光二极管裸片(221)。 夹套(11)具有与金属基底(21)的另一面(212)接合的联接表面(112)。 导热管(12)包括容纳在护套(11)的纵向孔(111)中的部分(123)。 护套(11)的联接表面(112)具有与纵向孔(111)连通的开口(114)。 导热管(12)的部分(123)的外周边(124)的一部分通过开口(114)与金属基板(21)的另一面(212)直接热接触 所述护套(11)吸收由所述发光二极管管芯(221)产生的热量。 翅片式散热器(13)安装在外壳(11)外部的导热管(12)的另一部分(121)上,以将传导至导热管(12)的热量散发到环境中。
