LIGHT EMITTING DIODE AND ITS MANUFACTURING PROCESS

摘要

PROBLEM TO BE SOLVED: To realize a high luminance light emitting diode in which efficiency for taking out light subjected to wavelength conversion by a phosphor can be enhanced and the volume and surface area of the phosphor can be increased.

SOLUTION: The light emitting diode 10 comprises a substrate 12, and a pair of external electrodes 14a and 14b extending from the surface of the substrate 12 to the rear surface thereof through the side face wherein an LED chip 16 is secured onto one external electrode 14a arranged on the surface of the substrate 12 and one electrode on the bottom face of the LED chip 16 is connected with one external electrode 14a. The other electrode on the upper surface of the LED chip 16 is connected with the other external electrode 14b through a bonding wire 18. Furthermore, the bonding wire 18 is inserted into a cut 23 formed in a nonwoven fabric 22 carrying a phosphor 20 so that the nonwoven fabric 22 is mounted on the upper surface of the LED chip 16, and the side face of the LED chip 16 is coated and sealed with a translucent coating material 27 mixed with the phosphor 20.
