An LED lamp assembly includes a fixing holder adapted for positioning the LED lamp assembly at a desired position and a plurality of LED lamp modules superposed one by one on the fixing holder and spaced from each other. The LED lamp modules gradually increase in dimension along a superposing direction of the LED lamp modules. Each of the LED lamp modules includes a heat sink and an LED module attached to the heat sink. The heat sinks of the LED lamp modules gradually increase in dimension along the superposing direction of the LED lamp modules. The LED lamp modules are connected by a rod between the heat sinks of adjacent ones of the LED lamp modules.

LED lamp assembly

An LED lamp includes a base, a heat sink placed on a top surface of the base and a plurality of LED modules mounted on the heat sink. The base has a base plate, an engaging flange extending upwards from an edge of the base plate and a plurality of projecting vanes formed on a bottom of the base plate. The heat sink surrounded by the engaging flange comprises a core, a plurality of branches extending outwards from an outer circumference of the core and a plurality of fins formed on two opposite sides of each branch. Each branch defines an inclined surface on a top thereof and has a height gradually decreased along a direction outwards from the core. Each LED module has a printed circuit board mounted on the inclined surface of a corresponding branch of the heat sink.

LED lamp

An LED lamp includes an LED module, a heat sink having a base abutting an upside of the LED module, a plurality of posts extending through the LED module and into the base of the heat sink, and a plurality of elastic members engaging the plurality of posts respectively and elastically abutting an underside of the LED module to secure the LED module to the base of the heat sink. The LED module is sandwiched between the base and the elastic members, and is thereby secured to the base of the heat sink.

LED lamp having elastic members for securing LED module to heat sink thereof

An LED lamp includes a base, at least first and second heat sinks, and at least first and second LED modules. The first heat sink includes a first heat absorbing surface and a first mounting surface which is mounted to the base, and defines axially a first through hole. The second heat sink includes a second heat absorbing surface and a second mounting surface which is mounted to the base. The second heat sink is received in the first through hole of the first heat sink. The second heat sink has a height greater than a height of the first heat sink whereby the second heat absorbing surface extends out of the first heat sink. The first and second LED modules are mounted on the first and second heat absorbing surfaces, respectively.

An LED lamp includes a fixing rod, a first heat sink mounted to the fixing rod, a second heat sink mounted on the first heat sink, a plurality of LED modules attached on the second heat sink and a lamp cover engaging the first heat sink to enclose the second heat sink and the LED modules. The second heat sink includes a plurality of heat-conducting faces formed on a bottom end thereof and arranged at different levels. The LED modules are respectively attached on the heat-conducting faces of the second heat sink. The lamp cover includes a panel and a plurality of annular steps extending outwardly from the panel in sequence. Each annular step has a concave lens attached thereon. The annular steps are located corresponding to the LED modules of the second heat sink, respectively.

An LED lamp comprises a heat sink with a plurality of LED modules attached thereon, an envelope receiving the heat sink and the LED modules, and a top cover and a bottom cover mounted at two ends of the heat sink via a plurality of fasteners and shafts with an elastic member coiled therearound. The top cover, the envelope and the bottom cover cooperatively form a sealed space receiving the heat sink and the LED modules. When the fasteners are fastened toward the heat sink, the shafts move upwardly relative to the bottom cover, whereby a distance between the top cover and the heat sink is decreased, so the heat sink makes tight contact with the top cover.
