LIGHT SOURCE MODULE

摘要

PURPOSE: A light source module is provided to improve heat dissipation by filling a thermal conduction material between a circuit board and a ceramic substrate. CONSTITUTION: A groove(112) is formed in a circuit board(110). A ceramic substrate(120) is inserted into the groove. At least one light emitting device is arranged on the ceramic substrate. A thermal conduction material(130) is filled in the inner part of the groove. The thermal conduction material is filled between the outer parts of the ceramic substrate.
