<p>Disclosed is a novel lighting device comprising a power source capable of supplying to a krypton lamp a voltage exceeding its rating, and a krypton lamp connected with an output terminal of said power source. Krypton 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 2,900K or higher which is very close to that of early morning sunlight. Thus, the lighting device is advantageously used in luminares in general.</p> |
