LIGHT EMITTING DEVICE

A light emitting device made in accordance with principles of the disclosed subject matter can provide countermeasures against static electricity and can be configured in a relatively small size. The lighting emitting device can include both a first conductor pattern and a second conductor pattern on an insulating board. In one example, a first LED chip having a high electrostatic breakdown voltage is electrically connected to the first conductor pattern and a second LED chip having a low electrostatic breakdown voltage is electrically connected to the second conductor pattern. The LED chips can be encapsulated with an encapsulating resin on the insulating board. At least part of the first conductor pattern is exposed at a farther position than a furthest portion of the second conductor pattern from a mounting surface so as to act as a lightning rod. Thus, the second LED chip having a low electrostatic breakdown voltage can be protected from static electricity by the first conductor pattern that is connected to the first LED chip.
