Method for manufacturing light emitting device
First Claim
1. A method for manufacturing light emitting devices comprising the steps of:
- providing a substrate;
providing and arranging a light emitting module on the substrate, said light emitting module having a light emitting unit and a sub-mount;
forming a first electrode and a second electrode, both of which are electrically connected to the light emitting unit by the sub-mount;
forming a first protective layer and a second protective layer with the first protective layer located over the first electrode and the second protective layer located over at the second electrode;
disposing a phosphor layer on the light emitting module with the phosphor layer covering both the light emitting module and the first and second protective layers;
removing part of the phosphor layer over the first and second protective layers; and
removing the first and second protective layers.

Abstract
A method for manufacturing light emitting device is provided. Firstly, provide a substrate. Then arrange a light emitting unit on the substrate. Next form at least one electrode and arrange at least one protective layer on the electrode. The protective layer is to prevent a phosphor layer following formed on the light emitting unit from covering the electrode. After forming the phosphor layer, flatten the phosphor layer and the protective layer. A part of the phosphor layer over the protective layer is removed. Thus the electrode is not affected by the phosphor layer and conductivity of the electrode is improved to resolve phosphor thickness and uniformity problems of the light emitting device. Therefore, the thickness of the light emitting device with LED is effectively reduced and stability of white color temperature control is significantly improved.
