Abstract
An anti-explosion single end tungsten halogen bulb is provided, which overcomes the defect of poor bulb safety in existing single end tungsten halogen bulb with the help of improved structure for a bracket glass rod. One end of the bracket glass rod supports the middle section of a filament and its another end is sealed into a whole with the end of a bulb shell; the two ends of the filament are connected electrically to two molybdenum pieces and two molybdenum feet in sequence. Because the filament is directly led out via the molybdenum piece and feet and the bracket glass rod separates the filament foot, no continuous arc will be formed in the bulb when the filament is burnt out, so that the bulb will not explode and the safety of bulb is greatly enhanced.
Description
Affiliated technical field
The utility model belongs to lighting technology, is used for indoor and outdoor lighting.
Background technology
At present, known direct all kinds of single end tungsten halogen lamps in civil power work are to be made of cell-shell, filament, bead support, two molybdenum sheets, two molybdenum pin etc., the bead support passes the seal wire of bead and some by a bead, two and is fixed on being configured on the bead, the scaffolding thread of bead support supports the filament mid portion firm, the two ends of filament are connected with two seal wires of bead support respectively, draw from an end of cell-shell through two molybdenum sheets and two molybdenum pin respectively again.Because the filament two ends are apart from expecting nearer and working in the 220V high pressure again, easily cause arcing therebetween, the special electric arc that produces when filament blow can be shifted to the seal wire root rapidly, if this moment, electric arc can not extinguish rapidly, arc energy is the seal wire scorification, even seal wire is burnt till metallic vapour, because seal wire is thicker, more metallic vapour sharply increases the cell-shell internal gas pressure, thereby causes the cell-shell blast.As seen, known single end tungsten halogen lamp security performance is relatively poor.
Summary of the invention
In order to overcome the existing relatively poor deficiency of single end tungsten halogen lamp security performance, the utility model provides a kind of security performance splendid explosion-proof single end tungsten halogen lamp.
The technical scheme that its technical problem that solves the utility model adopts is, a kind of explosion-proof single end tungsten halogen lamp is provided, this bulb comprises cell-shell, filament, support bead (or pipe, two molybdenum sheets and two molybdenum pin down together),, glass frosted pillar one end supports the filament mid portion firm, the other end and cell-shell port press seal are integral, and the two ends of filament are electrically connected in proper order with two molybdenum sheets, two molybdenum pin respectively.
The beneficial effects of the utility model are: because filament is directly drawn by molybdenum sheet, molybdenum pin.When filament blow, because electric field strength is the highest between filament pin, the electric arc that forms at breakpoint can shift between filament pin rapidly, because the wire foot of filament is very thin, its sectional area be the seal wire that is connected with wire foot in the existing single end tungsten halogen lamp 1/tens to one of percentage, even electric arc is with metallic vapour quantity pettiness that its scorification produced, and there is glass frosted pillar to intercept between wire foot, increased arcing distance, electric arc can not be kept, and will soon extinguish.Therefore, security performance of the present utility model is more more reliable than known single end tungsten halogen lamp.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is embodiment 1---the front view of the explosion-proof single end tungsten halogen lamp of the direct filament supports of glass frosted pillar one end.
