LED packaging structure and manufacturing method thereof

[0041]Example 1

[0042]This embodiment provides an LED package structure, referenceFigure 1-2 Including substrate 1, LED chip, transparent glue layer 2, white rubber layer 3, black rubber layer 4; LED chip is RGB chip.

[0043]The LED chip (not shown) is disposed on the substrate 1; the transparent glue layer 2 is laid on the substrate 1, and is coated on the LED chip; the transparent collapsed layer 2 is used to diverge with the LED chip emitted, and the light color of the LED is uniform. Sex; the white gelatin layer 3 is disposed outside the transparent glue layer 2 for reflecting the light on the white glue layer 3, avoiding a large amount of light absorbed by the black gum layer 4, improves the brightness of the LED; black rubber layer 4 Around the white glue layer 3, the contrast can be improved, and the light emitted by other LED chips is used to prevent the LEDs from appearing in a string light. The transparent collant layer 2, the surface of the white gelatin layer 3 and the black g

[0047]This embodiment provides a method of fabricating the LED package structure as described in Example 1. The following steps:

[0048]referenceFigure 4-6In step S10, the first wall 5 is enabled at the outer edge of the substrate 1, and the first wall 5 forms a groove 6 with the substrate 1, and the liquid-state transparent glue is added to the groove 6, and the liquid transparent glue is solidified. Layer 2;

[0049]Specifically, there are a plurality of LED chips (not shown) on the substrate 1; after the first wall 5 is provided on the substrate 1, the first wall 5 forms a groove 6 with the substrate 1, and the liquid transparent glue is added to form a transparent glue layer. 2.
