Abstract:
1. An illuminating device, adapted to a projecting apparatus, including: a lamp module, including: a lamp; an igniting module, capable of generating a high voltage signal to drive the lamp; and a plate, disposed between the lamp and the igniting module; and a lamp module holder, including: a power module, capable of generating a low voltage signal transmitted to the igniting module through a low voltage power line, and the igniting module capable of transforming the low voltage signal into the high voltage signal; a fan, disposed at a first side of the lamp and capable of cooling the lamp; and a connector, disposed on the low voltage power line, and making the lamp module separately assembled on the lamp module holder; wherein the plate is arranged to shield the igniting module from heat generated by the lamp, and to separate an airflow generated by the fan into a first part for cooling the lamp and a second part for cooling the igniting module.
