More Information
Summary:A light emitting device includes a first patterned electrode 12 and a second patterned electrode 13 both of which are formed on a wiring board 11, an LED chip 19 mounted on the second patterned electrode 13, a metal wire 20 electrically connecting the LED chip 19 and the first patterned electrode 12 to each other, and a lens member 21 made of a transparent synthetic resin for packaging the LED chip 19 and the metal wire 20. The first patterned electrode 12 is circular and formed with a cutout 14 at the center thereof. The second patterned electrode 13 is arranged in the cutout 14. With this arrangement, the lens member 21 can be formed into a predetermined configuration, while the reflection of light by the patterned electrodes can be ensured.
