Abstract
An LED lamp includes a heat sink, a plurality of vapor chambers mounted on the heat sink and an LED module mounted on the vapor chambers. The heat sink includes a base, a plurality of fins extending from a first surface of the base and a triangular ridge formed on a second surface opposite to the first surface of the base. The vapor chambers are mounted on the ridge of the base. The LEDs over two slopes of the ridge are oriented slantwise outwardly, thereby increasing an irradiation angle and area of the LED lamp.
Claims18
An LED lamp, comprising:
- a heat sink comprising:
- a base having a first surface and a second surface opposite to the first surface thereof;
- a plurality of fins extending from the first surface of the base with a plurality of channels defined between the fins;
- and
- a triangular ridge formed on the second surface of the base;
- a plurality of vapor chambers mounted on the ridge of the base;
- and
- an LED module mounted on the vapor chambers;
- wherein a plurality of steps is formed on two lateral sides of the ridge, and the steps on two lateral sides are symmetric respect to a top end of the ridge.
A heat dissipation device for dissipating heat from LED modules, comprising:
- a heat sink comprising a base having a plurality of fins on one side and a triangular ridge at an opposite side thereof adapted for mounting the LED modules thereon;
- and
- a plurality of vapor chambers mounted on the ridge, adapted for contacting the LED modules directly and transferring heat generated by the LED modules to the heat sink;
- wherein a plurality of slits are defined through two opposite side edges of the base and the fins at the two opposite side edges of the base.
An LED lamp comprising:
- a heat sink having a base with opposite first and second faces, a plurality of fins extending from the first face and a ridge formed on the second face;
- a plurality of vapor chambers mounted on the ridge;
- a plurality of printed circuit boards mounted on the vapor chambers;
- and
- a plurality of LEDs mounted on the printed circuit boards;
- wherein the ridge has a top end and two slopes beside the top end and the LEDs over the slopes are oriented slantwise outwardly away from the top end.
