Device for cooling the pinch seal of an electric lamp, and an electric lamp and an irradiation apparatus provided with this cooling device |
摘要 |
The pinch seal (12) of an electric lamp (11) is kept during operation at a lower temperature by a metal envelope (10), space between this metal envelope (10) and faces of the pinch seal (12) being filled with a heat-conducting mass comprising metal fibers. A considerable temperature decrease is obtained when the spaces between the oppositely arranged major surfaces (13) of the pinch seal (12) and the metal envelope (10) are filled with metal fibers.
