Abstract
An LED lamp includes a heat sink, an LED module received in the heat sink, a lamp holder disposed on a top end of the heat sink and covering the LED module, and a clip coupled to the lamp holder for securing the lamp holder to the heat sink. An annular fixing portion extends from a bottom of the lamp holder and surrounds a periphery of the top end of the heat sink. The clip hoops the fixing portion of the lamp holder and has a plurality of engaging portions extending through the fixing portion and inserted into the engaging slots of the heat sink correspondingly.
Claims16
An LED lamp comprising:
- a heat sink defining a receiving room in an end thereof, a plurality of elongated engaging slots are defined in an outer circumference of the heat sink;
- an LED module fixed on a bottom of the receiving room and thermally connecting with the heat sink;
- a lamp holder fixed on the end of the heat sink, having an annular fixing portion extending from a bottom of the lamp holder and surrounding the outer circumference of the heat sink near the end of the heat sink, wherein a plurality of elongated through holes are defined in the fixing portion and along a circumference of the fixing portion, the elongated through holes located corresponding to the engaging slots of the heat sink;
- and
- a clip coupled to the fixing portion of the lamp holder and having a plurality of engaging portions extending through the elongated through holes in the fixing portion and being correspondingly inserted into the engaging slots of the heat sink.
An LED lamp comprising:
- a heat sink comprising a central body and a plurality of fins extending outwardly from an outer circumference of the central body, a receiving room recessed in a top end of the central body, a plurality of engaging slots defined in an outer circumference of the fins at intervals;
- an LED module received in the receiving room and thermally connecting with the heat sink;
- a lamp holder disposed on a top end of the heat sink and comprising an annular frame and a lens positioned above the LED module, an annular fixing portion extending downwardly from a bottom of the annular frame and abutting against the outer circumference of the fins near the top end of the heat sink, wherein the fixing portion has a radius smaller than that of the frame;
- and
- a ring-shaped wire clip hooping the fixing portion of the lamp holder and having a plurality of engaging portions protruding inwardly, the engaging portions extending through the fixing portion of the lamp holder and inserted into the engaging slots of the fins of the heat sink, respectively, to thereby secure the heat sink to the lamp holder.
