Abstract

See full text

A multi-layer array type LED device is provided, which includes a substrate, an encapsulation body, two lead frames, a plurality of LED dices, and a set of optical lens. The outer circumferential edge and the upper and lower periphery of the substrate are completely encapsulated by the encapsulation body so that the multi-layer array type LED device can be tightly packaged. In the present invention, a fluorescent layer is disposed between an optical grease layer and a silica gel protection layer, and thereby the fluorescent layer is protected, and is capable of preventing moisture from permeating therein. On the other hand, in the present invention, the reflection coefficient of the optical grease layer is at least larger than a certain value so that the probability of the light emitted out of the optical chamber can be increased.
