Light emitting diode unit

摘要

A light emitting diode unit including a base (100) made of anodized aluminum and a printed board (101) attached to the base (100) and the printed board (101) including a predetermined conductive pattern (102) and an opening (101a) having an area for die-bonding at least one LED chip (113) to the base (100) through a transparent paste, an upper electrode of the at least one LED chip being wire-bonded to a conductive pattern (102) provided on the printed board (101) through a gold line (110), and a lens member (105) including at least two sealing resin-injection holes (106c) and being attached to the printed board (101) to form a space surrounding the at least one LED chip on the base, and the space being filled with the sealing resin by way of the resin-injection holes (106c) to seal the at least one LED chip.
