<P>PROBLEM TO BE SOLVED: To provide an LED lighting device which reduces the size of an optical source comprising an LED chip and color transformation component. <P>SOLUTION: The LED lighting device comprises: an LED chip 10; a circuit substrate 40 which is a base material with mounted LED chip 10; and a molded component molding, together with a transparent material, a fluorescent material which is excited by a light radiated from the LED chip 10 and radiates a light with a color different from that of a light emitted from the LED chip 10. A domy color transformation component 20 surrounding the LED chip 10 is provided, while an optical source comprises the LED chip 10 and color transformation component 20. The color transformation component 20 consists of a pair of halved materials 20a and 20b, wherein two notches 21, through which a bonding wires 14 connected to the LED chip 10 passes, are formed on one butting side between a pair of halved materials 20a and 20b. <P>COPYRIGHT: (C)2007,JPO&INPIT |
