PURPOSE: A light emitting device capable of being expended a lifespan provides a light emitting device in which maintenance and repair and installation are simple due to a simple structure of enhancing the efficiency for heat dissipation. CONSTITUTION: A base(10) is formed into metal on a flat board and has a support region(S) which is located in order to surround the edge of a light emission region(E). A pad part(14) is formed in the light emission region of the base and is consist of conductive material. A first insulating layer is included in between the base and pad part. A second insulating layer is included between each pad part. The emitting device is respectively excreted to the pad part. A supporting member(21) is formed into a flat type corresponding to a form of the support region and a sidewall expended from a base plane in the perpendicular direction. Light reflex is generated in the inner surface of the supporting member. An opposite member(24) is connected with the exterior of the supporting member and has the area which covers the entire light emission region. |
