Abstract
The utility model relates to a lighting source halogen bulb, specifically relates to an explosion proof high voltage single end halogen bulb. Comprises bubble (1), filament (3) in bubble (1), quartz glass bead (2) for supporting the filament, molybdenum foil (4) is connected with lamp foot (5), the utility model is characterized in that: quartz glass bead (2) is a cylinder, both ends are mounted with bubble (1), filament (3) is splay, hanging on the quartz glass bead (2), both ends of filament (3) is welded with molybdenum foil (4). The utility model has the advantages of: will not generate arc discharge, heavy current firstly blows out tungsten filament, bulb will not explode, so bulb may be used more safely and reliably; at the same time, the utility model features simple structure, low cost.
Description
Technical field
The utility model relates to the lighting source based on halogen bulb, is specifically related to a kind of explosion-proof high-pressure single end halogen bulb.
Background technology
Traditional high pressure single end halogen bulb in prior art, its filament and the molybdenum filament end that goes between is connected, and the molybdenum filament lead-in wire other end directly is connected with molybdenum foil, molybdenum foil is connected with lamp base again, the defective that such structure exists is if vacuum degree does not reach requirement in the bulb manufacture process, perhaps there are parts unclean, just are easy to cause bulb in use to blast, personal property is worked the mischief.Its reason is under high temperature and high effect of electric field, thin unclean gas in cell-shell or the parts can produce arc discharge between two molybdenum filament lead-in wires of bulb, the unconfined increase of electric current of molybdenum filament causes flowing through, the fusing point of molybdenum is 2620 β, the molybdenum filament overload produces high heat and burns under the effect of instantaneous large-current, makes the bulb blast.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned defective, a kind of explosion-proof high-pressure single end halogen bulb being provided.
The technical scheme that realizes the utility model purpose is: a kind of explosion-proof high-pressure single end halogen bulb, include cell-shell, be loaded on the filament in the cell-shell, the quartzy bead of filament supports, molybdenum foil is connected with lamp base, it is characterized in that: quartzy bead is cylinder, and two ends and cell-shell are inlayed, filament is splayed and hangs on the quartzy bead, and the two ends and the molybdenum foil of filament are welding.
Described cell-shell is concavity in the position of embedding mutually with quartzy bead.
Described quartzy bead is Z-direction and cell-shell embedding mutually.
Described quartzy bead is X-direction and cell-shell embedding mutually.
The utility model has the advantages that: can not produce arc discharge, big electric current at first with tungsten filament fusing, can not blast by bulb, makes bulb use safety and reliability; Simultaneously simple in structure, cost is low.
