Abstract
An LED package includes a light transmissive encapsulation, an LED die, a fluorescent layer, a baffle wall, a positive electrode and a negative electrode. The encapsulation includes a light emitting surface and a bottom surface opposite to the light emitting surface. The LED die, the fluorescent layer and the baffle wall are embedded in the encapsulation from the bottom surface side. The LED die includes a front surface for outputting light outward and a back surface opposite to the front surface. The front surface faces the light emitting surface of the encapsulation, and the back surface is exposed outside. The fluorescent layer is formed on the front surface of the LED die. The baffle wall surrounds the LED die and the fluorescent layer. The positive electrode and negative electrode are electrically connected to the LED die.
