摘要: The invention is directed to a lighting device, particularly a high-pressure metal halide lamp wherein a material combination of the body, frit and base materials is selected such that
a. the Coefficient of Thermal Expansion of the material of the frit material (CTE frit ) matches with the Coefficients of Thermal Expansion of the material of the lamp base (CTE base ) and the material of the body (CTE body ), respectively,
or
b. the material of the frit (CTE frit ) bridges with the Coefflcients of Thermal Expansion of the material of the lamp base (CTE bass ) and the material of the body (CTE body ), respectively,
at least at the joining surfaces of the body, frit and base materials, to sustain a hermetic bonding and withstand pressure and temperature conditions.摘要翻译: 本发明涉及照明装置,特别是高压金属卤化物灯,其中选择主体,玻璃料和基材的材料组合,使得a。 玻璃料材料的热膨胀系数(CTEfrit)分别与灯头材料(CTEbase)和本体材料(CTEbody)的热膨胀系数相匹配,或者b。 玻璃料(CTEfrit)的材料至少在本体,玻璃料和基体的接合表面处分别桥接灯基体材料(CTEbass)和本体材料(CTEbody)的热膨胀系数 材料,以维持气密性粘合并承受压力和温度条件。
