<P>PROBLEM TO BE SOLVED: To obtain an LED emitting a white color or pastel tone light easily and suitable for mass production, and its producing method. <P>SOLUTION: In the surface mounting LED 10, one wiring pattern, i.e, an electrode pattern 52, leading from an upper surface electrode through a side surface electrode to a lower surface electrode and the other wiring pattern, i.e, an electrode pattern 53, are formed on the opposite sides of a printed wiring board 51. The other electrode of an LED element 54 is connected with the upper surface electrode by means of a wire 55. At least the circumferential surface of the LED element 54 on the printed wiring board 51 is coated uniformly with a predetermined quantity of fluorescent substance 57 by ink jet system, or the like. Finally, it is sealed with a sealing resin 56, e.g. transparent epoxy resin, in order to protect the joints and wires 55 of the LED element 54 and to ensure effective emission of the LED element 54. <P>COPYRIGHT: (C)2003,JPO |
