Electric lamp having an envelope with an intermediate zirconium oxide coated layer |
摘要 |
An electric lamp having a glass lamp vessel 1 with a seal 7 coated with an intermediate coating layer of zirconium oxide 8. Lamp vessel 1 is connected at its seal 7 by a sealing cement 9 to a lamp cap 2. Zirconium oxide coating 8 completely separates seal 7 from sealing cement 9 and reduces mutual adherence therebetween. During operation of the lamp, zirconium oxide coating 8 reduces the thermal load and prevents cracking of seal 7 of lamp vessel 1.
