Examples
1 example 1
[0026] 1. Fix a plurality of light-emitting diodes 1 on the same surface of the fixing film 2 in an array with equal row and column spacing. Such as figure 1 Shown.
[0027] 2. Position the fixed film 2 tightly on the carrier 4 through the clamp 3, and make each light-emitting diode 1 face upwards, such as figure 2 Shown.
[0028] 3. Fix the steel mesh 5 on the fixing film 2, and use optical positioning components to make the light-emitting diodes 1 in the middle of each mesh of the steel mesh 5 one by one. Note: The mesh depth of the steel mesh 5 is slightly larger than the thickness of the light emitting diode 1. Such as image 3 Shown.
[0029] Use a spatula to fill the reflective glue 6 in each mesh of the steel mesh 5, such as Figure 4 Shown. After the reflective adhesive 6 is dried, it is separated from the steel mesh 5, and the reflective adhesive on the light-emitting surface of the light-emitting diode 1 is removed by grinding to obtain a semi-product such as Figure 5...

[0037] Others are similar, except that when designing the steel mesh 5, the mesh is designed into a bell mouth shape with an upper surface area larger than a lower surface area.
[0038] As a result, products such as Picture 8 Shown:
[0039] Two electrodes 8 are arranged on the bottom surface of the light-emitting diode 1, a phosphor glue layer 7 is arranged on the front surface of the light-emitting diode 1, and a reflective glue layer 6 is arranged on all four sides of the light-emitting diode 1.
[0040] The thickness of the reflective adhesive layer 6 close to the bottom surface is thinner than that close to the front surface.
[0041] The phosphor glue layer 7 may also be formed by multiple phosphor glue layers with different refractive indexes.
