摘要:
A high pressure discharge lamp includes a luminous bulb enclosing a luminous substance therein; and a sealing portion for retaining airtightness of the luminous bulb. The sealing portion has a first glass portion extending from the luminous bulb and a second glass portion provided at least in a portion inside the first glass portion, and the sealing portion has a portion to which a compressive stress is applied.

A high pressure mercury lamp (200) includes a luminous bulb (1) in which at least mercury (6) is enclosed inside the bulb, and a pair of sealing portions (2) that retain airtightness of the luminous bulb. The amount of the enclosed mercury (6) is 230 mg/cm 3 or more based on a volume of the luminous bulb, and heating means (10) for heating the luminous bulb is provided at least at part of the luminous bulb and the pair of sealing portions.

摘要:
A discharge lamp includes a luminous bulb in which a luminous material is enclosed and a pair of electrodes are opposed to each other in the luminous bulb; and a pair of sealing portions for sealing a pair of metal foils electrically connected to the pair of electrodes, respectively. The pair of metal foils have a pair of external leads on the side opposite to the side electrically connected to the pair of electrodes, respectively. At least one of the pair of external leads is joined to a lead wire for external connection that is to be electrically connected to an external circuit by the plastic flow of a caulking member.
摘要:
A short arc mercury lamp (100) includes a luminous bulb (10) enclosing at least mercury as a luminous material (18) and a pair of electrodes (12,12') opposed to each other; and a pair of sealing portions (20,20') for sealing a pair of metal foils (24,24') electrically connected to the pair of electrodes (12,12'), respectively. The electrode central axis (19) of one of the pair of electrodes (12) is dislocated from the electrode central axis (19') of the other electrode (12'). The shortest distance d (cm) between the head (112) of one of the electrodes (12) and the head (11b) of the other electrode (12') is larger than the value of (6M/13.6π) 1/3 when the total mass of the enclosed mercury is M(g).
摘要:
A high-pressure discharge lamp includes a glass housing (1) made of a high-melting vitreous material, a pair of sealing components (2) made of the same high-melting vitreous material and extended from the glass housing. A rare gas and a material (5) that is solid or liquid at room temperature is sealed inside the glass housing. Electrically conductive bars (3, 50) are embedded in the sealing components. The air-tight seals around the electrically conductive bars are formed such that at least one metal material selected from metals and oxides of said metals is provided near the regions lying between the high-melting vitreous material and the electrically conductive bar.
摘要:
A high pressure discharge lamp 100 comprises a luminous bulb 1 enclosing a luminous substance 6 inside and a sealing portion 2 for retaining the airtightness of the luminous bulb 1 . The sealing portion 2 has a first glass portion 8 extending from the luminous bulb 1 and a second glass portion 7 provided at least in a portion of the inside of the first glass portion 8 , and further has a portion ( 20 ) to which a compressive stress is applied. In the luminous bulb 1 , mercuric bromide (HgBr 2 ) is enclosed.
