An LED unit includes a plurality of LEDs, each of which includes a base, an LED die mounted on the base, a pair of leads penetrating the base to electrically connect with the LED die, a plurality of legs extending radially from a periphery of the base, a plurality of cutouts defined in the base and an encapsulant enveloping the LED die. The pair of leads of each LED are joined to corresponding leads of adjacent LEDs to realize electrical connections of the LEDs, while the legs of each LED are fitted into corresponding cutouts of the bases of adjacent LEDs to realize mechanical connections of the LEDs.
