A light distribution mechanism includes a connecting element, a light distribution element and a fixed cylinder. The connecting element is engaged with a heat sink of an LED downlight. The light distribution element is accommodated in the fixed cylinder, and the fixed cylinder has least two buckles extended outwardly from the top edge and passing through the latch grooves formed on the top and inner surfaces of the connecting element to achieve a latching effect. Since the fixed cylinder and the connecting element can be latched and engaged easily, users may remove the fixed cylinder and the light distribution element by bare hands anytime to change the light distribution element to a different light distribution angle before its reinstallation, to facilitate changing the light distribution element and adjust the light distribution angle of the LED downlight.
