Abstract
The utility model discloses a safe tungsten halogen bulb for stage lighting, which comprises bubble, filament, filament foot, support, molybdenum sheet, molybdenum pin, said support includes upper and lower quartz glass rods and a plurality of support hook fixed on quartz glass rod, filament middle is hung on support hook, both ends of two quartz glass rod for support are connected with bubble wall by fusing, both ends of filament are connected with filament foot, and two molybdenum sheets respectively. The utility model has good safety performance.
Description
Technical field
The utility model belongs to lighting technical field, relates in particular to the halogen tungsten bulb that is used for stage illumination, lighting.
Background technology
At present, the known halogen tungsten bulb that is used for stage illumination, lighting is made up of cell-shell, filament, support, two molybdenum sheets, two molybdenum pin etc.Support is made up of upper and lower two quartzy glass rod, two seal wires and several holder hooks of laterally placing, upper and lower quartzy glass rod is fixed on two seal wire tops and relies on seal wire to support, several holder hooks are separately fixed on the upper and lower quartzy glass rod, the filament middle part hangs between the upper and lower holder hooks, filament two ends wire foot is welded in respectively on two seal wires, two seal wires are connected with two molybdenum sheets respectively again, two molybdenum sheets are connected with two molybdenum pin respectively, two molybdenum pin are drawn from the cell-shell lower end, and cell-shell lower end and molybdenum sheet, molybdenum pin press seal are integral.The halogen tungsten bulb of this structure, because of its seal wire will support upper and lower two quartzy glass rods, diameter needs thicker, the electric arc that produces when filament blow can be shifted to the seal wire root rapidly, if this moment, electric arc can not in time extinguish, arc energy can be with the seal wire scorification, even seal wire is burnt till metallic vapour, thereby causes the cell-shell blast.As seen, known stage halogen tungsten bulb security performance is relatively poor.
The utility model content
In order to overcome the existing relatively poor deficiency of stage halogen tungsten bulb security performance, the utility model provides a kind of better safety performance safety halogen tungsten bulb.
The technical scheme that its technical problem that solves the utility model adopts is: the safe halogen tungsten bulb that is used for stage illumination, lighting, comprise cell-shell, filament, wire foot, support, molybdenum sheet, molybdenum pin, described support comprises upper and lower two quartzy glass rods and several holder hooks that are fixed on the quartzy glass rod, the filament middle part hangs on the holder hooks of support, two quartzy glass rod two ends of support are connected with the scorification of cell-shell wall respectively, and the filament two ends are connected with two molybdenum sheets respectively after respectively connecting wire foot.
Described support also comprises two supporting wires that are supported between the upper and lower quartzy glass rod.
The beneficial effects of the utility model are: because the utility model has adopted the supporting structure of no seal wire, the filament two ends connect wire foot and directly draw from molybdenum sheet, molybdenum pin, when filament blow, because of electric field strength between two wire foots is the highest, the electric arc that forms at breakpoint can shift to this place rapidly, because wire foot is very thin, even electric arc is with metallic vapour quantity pettiness that its scorification produced, electric arc can not be kept, and will soon extinguish, and can not cause the cell-shell blast.Therefore, fail safe of the present utility model will obviously be better than known stage halogen tungsten bulb.
Add two supporting wires between two quartzy glass rods, the spacing of fixing them earlier again with the cell-shell welding, can make filament draw more straight and uprightly like this.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of embodiment 1.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structural representation of embodiment 2.
Embodiment
As depicted in figs. 1 and 2, embodiment 1 is made of cell-shell 1, filament 2, wire foot 3, quartzy glass rod 4, holder hooks 5, supporting wire 6, molybdenum sheet 7, molybdenum pin 8.Upper and lower quartzy glass rod by about 2 supporting wires connect into integral body, on the quartzy glass rod that 3 holder hooks are fixed in the above, 2 holder hooks are fixed on the following quartzy glass rod in addition, the support of upper and lower quartzy glass rod, 5 holder hooks and 2 supporting wire formation embodiment 1.Filament 2 middle parts hang between the upper and lower holder hooks, and its two ends respectively connect wire foot 3, and wire foot 3 is connected with two molybdenum sheet 7 spot welding respectively, and molybdenum sheet 7 is connected with 8 spot welding of molybdenum pin again.Upper and lower quartzy glass rod two ends are connected with the glass wall scorification of cell-shell respectively, and the lower port of cell-shell and molybdenum sheet and molybdenum pin press seal are integral.
As shown in Figure 3, embodiment 2 only is that with the difference of embodiment 1 support of embodiment 2 does not have supporting wire.By contrast, embodiment 2 its filament in manufacture process is difficult for stretching, more loose.
The foregoing description is just to explanation of the present utility model; rather than to restriction of the present utility model; any innovation and creation that do not exceed in the utility model connotation scope; as by changing the modes such as quantity of quartzy glass rod, supporting wire and holder hooks, all be interpreted as falling within the protection range of the present utility model.
