Abstract
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.
Claims12
An LED lamp comprising:
- a fixing rod adapted for positioning the LED lamp at a desired position;
- a first heat sink mounted to the fixing rod;
- a second heat sink mounted on the first heat sink, the second heat sink comprising an upper portion near the first heat sink and a bottom end remote from the first heat sink, the second heat sink comprising a plurality of heat-conducting faces on the bottom end thereof distant from the first heat sink and arranged in sequence and at different levels, the heat-conducting faces gradually decreasing in dimension from outside to inside of the second heat sink;
- a plurality of LED modules attached on the heat-conducting faces of the second heat sink, respectively;
- and
- a lamp cover engaging the first heat sink to enclose the second heat sink and the LED modules, the lamp cover comprising a plurality of annular steps corresponding to the LED modules on the levels of the heat-conducting faces of the second heat sink, respectively, each step comprising a concave lens attached thereon;
- wherein light emitted by the LED modules respectively travels through the concave lenses of the annular steps of the lamp cover to generate a wide illumination area.
An LED lamp comprising:
- a fixing rod adapted for positioning the LED lamp at a desired position;
- a first heat sink fixed to the fixing rod, the first heat sink defining a receiving recession in a bottom thereof;
- a second heat sink received in the receiving recession and mounted on the bottom of the first heat sink, the second heat sink comprising a plurality of heat-conducting faces formed on an end portion thereof, the heat-conducting faces located on different levels;
- a plurality of LED modules respectively attached on the heat-conducting faces of the second heat sink;
- and
- a lamp cover engaging the receiving recession of the first heat sink to enclose the second heat sink and the LED modules, the lamp cover comprising a panel and a plurality of annular steps extending outwardly from the panel in sequence corresponding to the LED modules on the levels of the heat-conducting faces of the second heat sink, the annular steps gradually increasing in dimension remote from the panel of the lamp cover and each comprising a concave lens attached thereon;
- wherein light emitted by the LED modules respectively travels through the concave lenses of the annular steps of the lamp cover to generate a wide illumination area.
An LED lamp comprising:
- a first heat sink having a top and a bottom and a plurality of fins formed on the top thereof;
- a second heat sink mounted on the bottom of the first heat sink, the second heat sink comprising a plurality of heat-conducting faces located on a bottom end thereof and arranged in sequence and at different levels, dimensions of the heat-conducting faces and the different levels of the heat-conducting faces gradually decreasing from outside to inside of the second heat sink;
- a plurality of LED modules attached on the heat-conducting faces of the second heat sink, respectively;
- and
- a lamp cover engaging the first heat sink to enclose the second heat sink and the LED modules, the lamp cover comprising a plurality of annular steps corresponding to the LED modules, respectively.
