  • Publication number: 20100219441
    Abstract: An LED package structure and an LED packaging method are disclosed. The LED package structure includes a substrate, an LED unit and a transparent holding wall. The LED unit is electrically connected and located on the surface of the substrate. The transparent holding wall that corresponds to the LED unit is formed on the surface of the substrate, and has a receiving space. The LED unit is received in the receiving space. By utilizing the transparent holding wall, the colloid is controllably received in the receiving space and uniformly spread on the surface of the LED unit and around the LED unit. Thereby, the quantity of the colloid is easily controlled, and the LED package structure has a wide lighting angle due to the light emitted from the LED unit can pass through the transparent holding wall.
