Package process of light emitting element

Abstract

The invention relates to a package process of a light emitting element, comprising: an electrode setting step, an illuminant setting step, a contact step and a combining step. In the electrode setting step, a anode and a cathode are defined; in the illuminant setting step, a light emitting diode wafer having an anode and a cathode is used as an illuminant ; in the contact step, the defined anode and the cathode as well as the anode and the cathode on the light emitting diode wafer are communicated and combined into a whole; and in the combining step, the defined anode and the cathode and the light emitting diode wafer are tightly combined into a whole. In the package process of the light emitting element, the electrode of the light emitting diode wafer can be communicated with an outside electrode in advance, thereby work for assembling posterior-segment products can be simplified, the productivity can be increased, and the production cost can be reduced.

Description

Technical field [0001] The present invention relates to a packaging process for a light-emitting element, in particular to a process for manufacturing a light-emitting element with a light-emitting diode chip. The method can increase productivity and reduce manufacturing costs, and can make the manufactured light-emitting element The luminous efficiency is improved. Background technique [0002] In the prior art production of light-emitting elements with light-emitting diode chips, the light-emitting diode chips are first manufactured, and then the light-emitting diode chips are fixed in a base with a recessed portion by a bonding material, and the When the recess is filled, the manufacture of the light-emitting element is completed. However, the light-emitting diode chip must be electrically connected to an external circuit through its electrodes to be able to emit light. Therefore, in the manufacturing process of the aforementioned light-emitting element, a contact point that c...

Problems solved by technology

However, the light-emitting diode chip must be electrically connected to the external circuit through the electrodes on it to be able to emit light. Therefore, in the manufacturing process of the aforementioned light-emitting element, a contact point that can be electrically connected must be reserved at the electrode. Leaving steps not only creates a bottleneck in the process, but also causes secondary processing operations that are necessary when connecting external circuits

[0003] Furthermore, in the structure of the existing light-emitting element, the light-emitting diode chip is bonded by the bonding material, so the heat conduction will be limited between the layers Factors such as the contact interface of each layer and the different thermal conductivity coefficients of each layer directly affect the luminous performance and working life of the light-emitting element, and the light emitted by the light-emitting element can only directly pass through the filling material to the outside, and a small part passes through the side of the concave part. Reflection passes through the filler material to the outside world, therefore, the luminous efficiency is not as expected
