Abstract

A light emitting device has a plurality of conductive members with good heat conductivity provided in a base member, the conductive members are isolated by insulating members provided between the conductive members. A light emitting element device is mounted on the base member. An light emitting diode is provided in the light emitting device and mounted on conductive member. A projection is outwardly projected from the heat conductive member for cooling the LED.

Description

Background of the invention [0001] The present invention relates to light emitting devices using light emitting diodes. [0002] Fig. 16 is a perspective view of a conventional light emitting device disclosed in Japanese Patent No. 3,302,203. The light emitting device 1 comprises a substrate 2 made of resin such as epoxy resin, a pair of electrodes 2a and 2b fixed on the upper and lower sides of the substrate 2, an LED 3 mounted on the electrode 2a and connected to the electrode 2b via a wire 4, and The sealing member 5 made of transparent resin is used to seal the LED3. [0003] The light emitting device 1 is mounted on a printed substrate 6, and the electrodes 2a, ab are connected by a pair of conductive patterns 6a, 6b. [0004] The LED 3 emits light 7 when current is supplied to the LED 3 from the patterns 6a, 6b through the electrodes 2a, 2b. [0005] Since the light emitting device is mounted on the printed substrate 6 through the thin electrodes 2a, 2b, the thickness...
