Light-emitting module

摘要

A light-emitting module according to the present invention contains a Peltier element driver, and a signal processor for controlling the Peltier element driver. The Peltier element driver is mounted on a first substrate, which directly attaches to the inner bottom surface of the housing, while the signal processor is mounted on the other substrate spaced to the first substrate. The first substrate and the other substrate are vertically integrated within the housing. This arrangement enables to encase the Peltier element driver and the signal processor in the housing with effective thermal dissipation.
