A light emitting module (10) includes a metal circuit board (11), a number
of light emitting units (12) arranged on a first surface of the metal
circuit board, and a cooling system (13) mounted on an opposite second
surface of the metal circuit board. A light source device (1) using the
light emitting module further includes a housing (30) and a transparent
light cover (20). The housing has a base with the light emitting module
being mounted thereon. The transparent light cover covers the housing.
The present light emitting module and light source device can improve the
brightness of the light, and increase the utilization efficiency of
light.
