Abstract
The present disclosure provides a light emitting diode package which includes a plurality of electrodes, an LED die, a reflecting cup, and a phosphor layer. The LED die are electrically connected with the electrodes. The LED die includes a top light emitting surface and a plurality of lateral sides extending downward from the top light emitting surface. The reflecting cup is formed on the electrodes and surrounds the LED die. The reflecting cup includes an inner surface. The inner surface contacts with bottom portion of the LED die. A cavity is defined between the inner surface and other portion except the bottom portion of the LED die. The phosphor layer covers and seals the LED die.
