Abstract
An LED assembly for an LED lamp includes a replaceable bracket and a plurality of LED units mounted on the bracket. The bracket includes a frame and a plurality of mutually crossed beams interconnected in the frame to define a plurality of square openings. Each LED unit includes a printed circuit board, a heat sink secured below the printed circuit board and fixed on the bracket, and a plurality of LEDs mounted on the printed circuit board to be exposed in the openings in the bracket. The bracket can have different configuration so that light beams generated by the LEDs are parallel to each other, in a convergent manner or in a divergent manner.

An LED assembly for an LED lamp comprising:
- a bracket adapted for being mounted in a lamp housing of the LED lamp;
- and
- a plurality of LED units attached on the bracket, wherein each of the plurality of LED units comprises a printed circuit board, a plurality of LEDs mounted on the printed circuit board, and a heat sink fixed on the printed circuit board for dissipating heat from the plurality of LEDs;
- wherein the plurality of LEDs and the heat sink of the each of the plurality of LED units are located at two opposite sides of the printed circuit board;
- wherein the heat sink of the each of the plurality of LED units comprises a base in thermal contact with the printed circuit board and a plurality of fins extending from the base in a direction remote from the plurality of LEDs;
- and
- wherein the base of the heat sink is in the form of rectangular shape, the base forming four ears at four lateral sides thereof, respectively.
An LED assembly for an LED lamp comprising:
- a replaceable bracket adapted for being fixed in a lamp housing of the LED lamp, the bracket defining a plurality of openings;
- and
- a plurality of detachable LED units secured on the bracket to expose LEDs thereof in the openings in the bracket, wherein each of the LED units has a printed circuit board having a first face on which corresponding LEDs are mounted and an opposite second face on which an individual heat sink is mounted to absorb heat generated by the corresponding LEDs;
- wherein the individual heat sink has a base engaging with the second face of the printed circuit board and a plurality of fins extending perpendicularly from the base in a direction away from the printed circuit board;
- wherein the base of the individual heat sink is in the form of rectangular shape and has four ears at four lateral sides thereof, respectively.
