[0093] The light-emitting devices of several embodiments of the present invention are explained below with reference to the accompanying drawings, in which the same reference characters in all several views indicate the same or corresponding parts.
[0094] figure 2 The light emitting device 200 of the embodiment of the present invention is shown. In the light emitting device 200, the bottom 11 of the base 100 for the LED is in thermal contact with the metal plate 30 of the circuit board 300. The base 100 has a mounting base 10 and a light emitting diode (LED) chip 5 mounted on the mounting base 10, and the mounting base has wires 12-14 and 13-17. The LED chip 5 is shown along perpendicular to it figure 2 The direction of the paper is issued by the harness. The circuit board 300 has a metal plate 30 and a metal pattern 41 for electrical conductors formed on the electrical insulating layer 40. The LED chip 5 has a gallium nitride semiconductor. In this embodiment and the followi...
