A narrower LED package structure with sideways output of light suitable for a light guide plate includes two first electrodes, a package body, a cover layer, and two second electrodes. The LED chip is mounted on the first electrodes. The package body encapsulates the first electrodes, and surrounds the LED chip to define a light emitting region. The cover layer infills the light emitting region and covers the LED chip. The second electrodes are positioned outside the package body. Along a plane parallel to the first electrodes, a surface area of the two second electrodes is greater than a surface area of the portion of the two first electrodes positioned in the light emitting region.

Side-view light emitting diode package structure

A light emitting diode package includes a light emitting diode chip, a light conversion layer covering the light emitting diode chip, a reflecting layer surrounding the light emitting diode chip. The light emitting chip has a light output top surface, a first electrode and a second electrode. The first electrode and the second electrode are opposite to the light output top surface. The light emitting diode package further includes a supporting layer made of metal material. The supporting layer is mounted on a bottom surface of the reflecting layer facing away from the light output top surface and surrounds the light emitting chip and the light conversion layer.

Light emitting diode package

A vertically shallow LED package structure includes at least one LED chip, a package layer, and a first cover layer. Each LED chip includes a first bottom surface. The package layer covers and wraps around each LED chip, and can absorb light emitted by each LED chip and emit light with a different preset wavelength. The package layer includes a second bottom surface facing the first bottom surface, a first side surface perpendicular to the second bottom surface, and a convex surface interconnecting the second bottom surface and the first side surface. The convex surface protrudes away from the LED chip. The convex surface can reflect the light with the preset wavelength towards the first side surface. The first cover layer covers the package layer and exposes the first side surface.
