Problems solved by technology

However, when the user connects the light-emitting diode to an external electronic device, the polarity of the electrodes in the light-emitting diode is often unclear, and the electrode is connected to the external electronic device (or power supply) in reverse, resulting in damage to the light-emitting diode.

Embodiment Construction

[0057] Figure 1 to Figure 11 It is a schematic diagram for illustrating the manufacturing process of the light emitting device according to the first embodiment of the present invention. Figure 12 is a schematic top view of the light emitting device of the first embodiment. Figure 13 yes Figure 12 A schematic cross-sectional view along the section line A-A' in .

[0058] Please refer to figure 1 , a release film 30 is provided, and the release film 30 is, for example, a double-sided adhesive film. Next, fluorescent colloid PC is formed on the release film 30 . The fluorescent colloid PC can be formed by mixing phosphor powder and colloid (such as silica gel).

[0059] Please refer to figure 2, let the fluorescent colloid PC stand for a period of time, such as 24 hours later, due to gravity, most of the phosphor powder in the fluorescent colloid PC will settle below, while a small amount of phosphor powder will still remain on the top, and the above-mentioned standin...

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 lightemitting 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.

Description

technical field [0001] The present invention relates to a light-emitting device and a manufacturing method thereof, and in particular to a light-emitting device using a light-emitting diode as a light source and a manufacturing method thereof. Background technique [0002] Light Emitting Diodes (LEDs) are widely used in lighting fields due to their advantages of high energy conversion efficiency, short response time, and long life. However, when the user connects the light-emitting diode to an external electronic device, the polarity of the electrodes in the light-emitting diode is often unclear, and the electrodes are connected to the external electronic device (or power supply) in reverse, resulting in damage to the light-emitting diode. Contents of the invention [0003] The invention provides a light-emitting device, which can greatly reduce the probability of the user connecting the electrodes in reverse. [0004] The invention provides a method for manufacturing a l...
