ABSTRACT:
Disclosed is a novel lighting device comprising a power source capable of supplying to an argon lamp a voltage exceeding its rating, and an argon lamp connected with an output terminal of said power source. Argon lamp emits a natural light when lighted by energizing a voltage exceeding the rating. Such a light has superior color rendering properties, as well as a color temperature of about 2,900.degree. K. or higher which is very close to that of that of early morning sunlight. Thus, the lighting device is advantageously used in luminares in general.
