Abstract
A light emitting device including a light emitting unit and a phosphor resin layer is provided. The light emitting unit has a top surface and a bottom surface opposite to each other. Each of the light emitting units includes two electrodes. The two electrodes are disposed on the bottom surface. The phosphor resin layer is disposed on the top surface of the light emitting unit. One side of the phosphor resin layer has a mark. One of the two electrodes is closer to the mark with respect to the other one of the two electrodes.
Claims17
A light emitting device, comprising:
- a light emitting unit, having a top surface and a bottom surface opposite to each other, and each of the light emitting units comprising two electrodes, wherein the two electrodes are disposed on the bottom surface;
- and
- a phosphor resin layer, disposed on the top surface of the light emitting unit, wherein a mark is formed on one side of the phosphor resin layer,
- wherein one of the two electrodes is closer to the mark with respect to the other one of the two electrodes.
The light emitting device as claimed in claim I, wherein the phosphor resin layer comprises a low-concentration phosphor resin layer and a high-concentration phosphor resin layer stacked with each other, and the high-concentration phosphor resin layer is located between the light emitting unit and the low-concentration phosphor resin layer.
A manufacturing method of a light emitting device, comprising:
- forming a phosphor resin layer;
- performing a first cutting procedure to the phosphor resin layer to form a plurality of first grooves in the phosphor resin layer, so as to separate the phosphor resin layer into a plurality of portions, wherein each of the portions serves as a bonding area;
- providing a plurality of light emitting units, wherein each of the light emitting units comprises two electrodes;
- respectively forming a plurality of marks at a side of each of the portions of the phosphor resin layer;
- respectively bonding the light emitting units to the bonding areas, wherein each of the marks is closer to one of the two electrodes of the corresponding light emitting unit and is farther away from the other one of the two electrodes;
- and
- performing a final cutting procedure along the first grooves to form a plurality of the light emitting devices.
