Light emitting diode package with light reflecting cup internally slanted

A light emitting diode (LED) package comprising:

• a base;
• a plurality of electrodes formed on the base;
• an LED chip electrically connecting the electrodes;
• and
• a reflecting cup mounted on the base and surrounding the LED chip therein, the reflecting cup comprising a bottom surface, a top surface substantially parallel to the bottom surface, an outer surface interconnecting outer edges of the bottom surface and the top surface, and an inner surface interconnecting inner edges of the top surface and the bottom surface;
• wherein the inner surface comprises a reflecting portion and a transition portion, the reflecting portion extends slantwise downwardly from the top surface, the transition portion extends slantwise downwardly from the reflecting portion, the transition portion surrounds and defines a through hole of the reflecting cup, the LED is received in the through hole, the reflecting portion is positioned to reflect light emitting from the LED chip, an angle α is defined between a transverse cross-section of the reflecting portion and an imaginary surface parallel to the bottom surface, an angle β is defined between a transverse cross-section of the transition portion and the bottom surface, and the angle β is larger than the angle α.
