Patent ID: 7177333

Claim:
A laser LED device comprising: a heat sink, said heat sink having a front side, a back side, and a plurality of pins respectively extended from said back side for bonding; a mount provided at the front side of said heat sink; a submount disposed at said mount; a laser diode chip and a photo diode chip provided at the front side said heat sink; and a metal cap bonded to the front side of said heat sink; wherein an automatic power control circuit is encapsulated in said metal cap and uses said laser diode chip to detect a beam being emitted from a rear end of said laser diode chip and is electrically connected to bonding pins of said heat sink, said laser diode chip, and said photo diode chip by wires, said automatic power circuit is further connected to a first pin and a second pin that are electrically connected to a power+, power− and a third pin for being connected to an external variable resistor; and said laser diode chip is mounted to said submount and said photo diode chip and said automatic power control circuit are mounted in a recessed hole in a front side of said heat sink.
