Abstract
An LED lamp includes a post (10), a heat sink (20) enclosing the post, an LED module (30) mounted in the post, a holder (40) secured on the LED module, and a lens (50) covering the holder. The heat sink is formed by a plurality of fins (22), each having an annular and planar configuration to contact and surround the post. The fins are parallel to each other and mounted on the post along a length direction of the post. An LED (32) of the LED module is received in the holder, whereby light generated by the LED is reflected by the holder.
Claims17
An LED lamp comprising:
- a cylindrical post defining an opening therein;
- an LED module received in the opening;
- a holder mounted on the LED module and partly received in the opening, wherein at least an LED of the LED module is received in the holder whereby a light generated by the at least an LED is reflected by the holder;
- a lens accommodated in the holder and covering the at least an LED of the LED module;
- and
- a heat sink consisting of a plurality of parallel fins each having an annular configuration surrounding the post, whereby heat generated by the at least an LED is dissipated by the fins via the post.
An LED lamp comprising:
- a cylindrical support having a pair of arced strips thereon;
- an LED module mounted on the cylindrical support and surrounded by the pair of arced strips;
- and
- a plurality of fins stacked around the cylindrical support along a height direction thereof, wherein each of the plurality of fins has an annular and planar configuration mounted around the cylindrical support.
An LED lamp comprising:
- a cylindrical post having a recessed top end and a mounting portion below the recessed top end;
- an LED module received in the recessed top end and secured to the mounting portion;
- a holder received in the recessed top end, wherein least an LED of the LED module is received in the holder so that a light generated by the at least an LED is reflected by the holder, the holder having a tapered upper portion located over the recessed top end;
- and
- a plurality of parallel fins soldered to a circumferential periphery of the post along a length direction thereof.
