ABSTRACT:
A combination lamp includes a first light and a second light. The first light includes a discharge lamp and serves to generate light. The second light serves to generate light and also heat, and thereby serves to heat the discharge lamp. Accordingly, the second light can preheat the discharge lamp. This preheating allows the discharge lamp to produce adequate luminous energy immediately when the discharge lamp is turned on.
