LIGHT-EMITTING ELEMENT ARRAY

摘要

PURPOSE: A light emitting element array is provided to increase heat dissipation by forming a heat radiation hole corresponding to a hole formed in a connection pattern and a heat radiation pattern on the lower side of the heat radiation hole. CONSTITUTION: A printed circuit board(120) includes a base substrate, a copper foil pattern and an insulating member. The copper foil pattern includes an electrode pattern and a connection pattern connecting a space between electrode patterns. First to sixth light emitting element packages(111-116) are mounted on the printed circuit board. The electrode pattern and the connection pattern connect the first to sixth light emitting element packages. A heat radiation hole is formed on a base substrate to correspond to a hole.
