Abstract
A light source module including a ceramic substrate, copper traces, light emitting units, and heat conductive columns is provided. The first heat conductive column and the second heat conductive column correspond to the first light emitting unit and the second light emitting unit respectively. The negative electrode of the first light emitting unit is connected to the first copper trace, the positive electrode of the second light emitting unit is connected to the second copper trace, and the positive electrode of the first light emitting unit and the negative electrode of the second light emitting unit are connected to the third copper trace. An end of the first heat conductive column is connected to the positive electrode of the first light emitting unit, and an end of the second heat conductive column is connected to the negative electrode of the second light emitting unit.
