Embodiment Construction

[0024] Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

[0025] Here, reference numeral 1 denotes a bulb envelope of a halogen lamp, and 2 denotes a glass envelope, which is sealed in such a manner that one end thereof is closed by a press-seal portion 3 and the other end thereof is closed by an exhaust portion 4 . The lead wires 5 are inserted into the pinch sealing parts 3 while the middle parts of the lead wires 5 are clamped in the pinch sealing parts 3 respectively.

[0026] Also, the thickness of the portion near the bottom end of the pinch portion 3 of the pinch portion side end portion 6 of the glass envelope 2 is thicker than other portions, thereby constituting the thick portion 7 .

[0027] The thick portion 7 is formed in such a way that it protrudes outward (downward) from the glass envelope 2, and the lower surface of the thick portion 7 is almost at right angles to the press-seal portion ...

Abstract

An electric lamp with a base, in which a bulb envelope comprising a pinched portion 3 at one end of the glass envelope is connected to a support plate in such a way that the pinched portion is supported by support pieces respectively arranged in the support plate, and supported Between the support pieces, the thickness of the portion of the glass envelope side end portion engaging the glass envelope side support piece of the support tray is greater than the thickness of the rest of the pressure seal portion side end portion.

Description

technical field [0001] The invention relates to an electric lamp with a base, as well as a bulb envelope and a support plate for supporting the bulb envelope, in which the bulb envelope includes a pinch portion formed by one end of a glass envelope arranged in the bulb envelope, supporting The plate comprises two or more support plates, the pinch portion of the bulb envelope can be connected to and supported by the support plate in such a way that the pinch portion of the glass envelope of the bulb envelope is supported by the support plates of the support plate, and supported between the support plates, the invention relates in particular to a technique for preventing damage to the glass envelope of the bulb envelope during and after supporting the bulb envelope with the support discs. Background technique [0002] Image 6 with 7 An example of a common electric lamp with a base is shown. [0003] In these figures, reference symbol a denotes a bul...
