Patent ID: 6934309

Claim:
A two-dimensional light-emitting device comprising: a plurality of stacked light-emitting units, each of said light-emitting units comprises: a cooling assembly, a laser diode bar arranged on the cooling assembly to be thermally and electrically connected with the laser diode bar, at least a part of said cooling assembly serving as a first electrode of each light-emitting unit, and a tape-automated-bonding sheet including an electrically conductive layer and an insulating layer and arranged between adjacent ones of the cooling assemblies such that said insulating layer confronts a surface of the cooling assembly on which the laser diode bar is arranged, said electrically conductive layer including a webbed extending section to electrically connection with the laser diode bar and serving as a second electrode of each said light-emitting unit, the webbed extending section having slits formed therein to prevent stress on the laser diode bar, wherein said first electrode and said second electrode of each said light-emitting unit are electrically isolated from each other by said insulating layer.
