Abstract

A light emitting device includes a first metal plate, a second metal plate, and light emitting elements between the metal plates. The device further includes a wavelength conversion member excited by a first light from the light emitting elements to emit a second light having a wavelength different from the first light, a bulb including a base, a first lead connected to the first metal plate, and a second lead connected to the second metal plate. The base of the bulb includes terminals connected to respective leads. The conversion member covers the light emitting elements entirely, opposite surfaces of the first metal plate partially, and opposite surfaces of the second metal plate partially. The first lead is connected to a portion of the first metal plate exposed from the conversion member, and the second lead is connected to a portion of the second metal plate exposed from the conversion member.
