Abstract
A two-dimensional LD (laser diode) array light-emitting device constituted by stacking light-emitting units each having a LD bar and a cooling assembly for cooling the LD bar with a simplified electrical connection structure to reduce manufacturing cost. The cooling assembly is electrically connected with one electrode of the LD bar through the die spacer so that a part of the cooling assembly serves as one electrode of the light-emitting unit. The other electrode of the LD bar is electrically connected with a webbed extending section of a conductive layer of a TAB (tape-automated bonding) sheet so that the conductive layer serves as the other electrode of the light-emitting unit. A space between the adjacent cooling assemblies for arranging the LD bar is adjusted by the spacer sheet intervened between the TAB sheet and the cooling assembly.
