    • An LED lamp includes a heat dissipation device and a plurality of LED modules. The heat dissipation device includes a heat conductive member and a fin unit. The LED modules are attached to a top surface of a first plate of the heat conductive member. The heat conductive member comprises a plurality of posts embedded in the top surface of the first plate. Peripheries of the first and second plates are in a hermetical conjunction with each other to form a chamber containing phase-changeable working fluid therein. The first plate has a plurality of receiving recessions which are depressed downwardly from the top surface thereof and respectively receive the posts. Screws are used to extend through the LED modules to threadedly engage in the posts thereby to intimately mount the LED modules on the top surface of the first plate of the heat conductive member.
    • LED灯包括散热装置和多个LED模块。 散热装置包括导热构件和翅片单元。 LED模块附接到导热构件的第一板的顶表面。 导热构件包括嵌入在第一板的顶表面中的多个柱。 第一和第二板的周边彼此密封结合以形成其中包含相变工作流体的室。 第一板具有从其顶表面向下压下并分别接收柱的多个接收凹部。 螺丝用于延伸通过LED模块以螺纹地接合在柱中,从而将LED模块紧密地安装在导热构件的第一板的顶表面上。
