PURPOSE: A light emitting device is provided to improve heat radiation compared with a conventional device by including at least one uneven dissipation pattern on at least one side of a substrate. CONSTITUTION: A light emitting device includes a substrate(10), a light emitting device, a heat uneven dissipation pattern(35), and an electrode. The light emitting device is mounted in one side of the substrate. The heat uneven dissipation pattern is formed at least one side of the substrate. The electrode covers the at least part of the uneven dissipation pattern and is connected to the light emitting device.
