LIGHT SOURCE UNIT FOR PROVIDING LIGHT EMITTING ARRAY WITHOUT INCREASING COSTS BY USING LIGHT EMITTING ELEMENT

摘要

PURPOSE: A light source unit is provided to give a light emitting array having improved heat radiation property by using at least one light emitting element. CONSTITUTION: A light source unit includes at least one light emitting element, a printed circuit board(21), and an attachment stand(22). The light emitting array has a plurality of light emitting elements arranged in line. The printed circuit board(21) is separately provided from the light emitting element array. The printed circuit board(21) has a printed circuit pattern to be bonded with the light emitting element array by wires. The attachment stand(22) has the light-emitting element array and the printed circuit board fixed thereto. The attachment stand(22) is formed with a V-shaped groove for placing the light emitting element array. The groove has a side wall disposed as a reflection plane in a longitudinal direction of the light emitting element array.
