Abstract

PURPOSE:To improve the mechanical strength of a compact type fluorescent lamp by airtightly bonding a glass cover along an opening section that seals both the outer and inner bodies of an enclosure device and reducing the pressure of its spacial area under vacuum or atmospheric pressure. CONSTITUTION:A meandering groove 6 is formed as a discharge path by overlapping both the outer and inner bodies 2 and 3 of an enclosure device made of a glass material with a curved surface and electrodes 7 and 8 are retained at the end of the groove 6. Simultaneously a compact type fluorescent lamp is formed by coating the inner surface of the groove 6 with a phosphor and sealing rare gas and mercury. Besides, both the outer and inner bodies 2 and 3 are airtightly bonded at an opening section 4 using glass frit 5 and a disk-shaped glass cover 15 is also airtightly bonded along the opening section 4 and then the pressure of an enclosed spacial area 16 is reduced up to the pressure of one of several fractions of vacuum or atmospheric pressure. As a result, the strength of the inner body 3 can be improved and its damage can be prevented and its quality can be improved.

As the next step, the inventors began manufacturing the above-mentioned compact fluorescent lamp. However, various unexpected problems were found in the manufacturing process, and the patent application
As pointed out in No. 5-64511 (see JP-A-56-160764), the biggest problem was that the container inner body 3 was easily damaged during the lamp evacuation process and after completion. This is because the provision of the groove 6 in the container inner body 3 reduced its mechanical strength;
This is because the inner body 3 of the container 3 is subjected to so-called tensile stress in the outward direction due to the difference between the atmospheric pressure and the rare gas filling pressure of several Torr inside the luminescent container 1. The reason why the outer bulbs of ordinary vacuum light bulbs and high-pressure sodium lamps are not damaged is thought to be because they are subjected to so-called compressive stress inward. The susceptibility of the tab 9 and the enclosure inner body 3 to damage is a problem inherent in new compact fluorescent lamps.
