Abstract:
1. A method for packaging a light emitting device, comprising: a step of providing a carrier formed with electrodes including an anode electrode and a cathode electrode, said anode electrode and said cathode electrode being in direct contact with said carrier; a step of providing a light emitting diode (LED) chip served as a light emitting object, the light emitting diode chip having a positive electrode and a negative electrode; a step of directly contacting the anode electrode and the cathode electrode of the carrier with the positive electrode and the negative electrode of the light emitting diode chip to establish electrical communication, said positive electrode and negative electrode of said light emitting diode chip directly overlaying said anode electrode and cathode electrode of said carrier; a step of firmly bonding the carrier with the light emitting diode chip wherein the step of firmly bonding the carrier with the light emitting diode chip is through a way of being continuously compressed and heated or through an adhesive to join the anode electrode and the cathode electrode of the carrier with the positive electrode and the negative electrode of the light emitting diode chip; a step of reflection defined by coating a first metal layer of high reflection coefficient after the carrier and the LED chip are contacted to each other, the first metal layer being rolled and compressed or stamped onto the carrier and the LED chip; a step of heat dissipation defined by coating a second metal layer of high thermal conductivity coefficient on the first metal layer, the second metal layer being rolled and compressed or stamped onto the first metal layer, and distinct from said first metal layer.
