ABSTRACT:
A semiconductor light-emitting device according to an embodiment of the present invention includes chip LEDs formed on a silicon submount, in which a wiring pattern having a chip connecting terminal portion connecting the chip LEDs, an external connecting terminal portion connecting an external unit, and a plurality of lead portions connecting a corresponding chip connecting terminal portion and a corresponding external connecting terminal portion is formed on the silicon submount, and an area of the chip connecting terminal portions is made larger than an area of a region where the chip connecting terminal portion overlaps with the chip LEDs. Accordingly, a semiconductor light-emitting device of high heat radiation property and heat resistance can be provided.
