White light emitting device and manufacturing method thereof

A white LED comprising:

• a lead frame having a pair of external lead terminals, each spaced a predetermined distance apart, and one tip end of the external lead terminal being formed with a cup-shaped reflector plate;
• a LED bonded to the reflector plate of the lead frame;
• a wire electrically connecting the LED to a pair of external lead terminals of the lead frame;
• polymeric resin encompassing the LED and coated with the reflector plate and in which organic phosphors are solved and inorganic phosphors are dispersed;
• and
• a molding part so molded as to encompass the polymeric resin, the entire length of the wire and part of the lead frame.

A manufacturing method of a white LED comprises the steps of:

• bonding an LED to a reflector plate of a lead frame formed with a pair of external lead terminals, each spaced a predetermined distance apart, and with the cup-shaped reflector plate at one tip end of an external lead terminal;
• bonding the LED to the lead frame with a wire;
• coating to the reflector plate of the lead frame a polymeric resin in which organic phosphors are solved and inorganic phosphors are dispersed to encompass the LED;
• and
• implementing a molding process of encompassing a part of the lead frame with a transparent material for protecting the LED from the outside environment.

A method of manufacturing a white LED comprises the steps of:

• solving organic phosphors and organosillicates in polymeric resin;
• dispersing inorganic phosphors in the polymeric resin solved therein with the organic phosphors and the organosillicates;
• and
• encompassing an LED with the polymeric resin solved therein with the organic phosphors and the organosillicates and dispersed therein with inorganic phosphors and coating the LED with the polymeric resin.
