Description
The utility model relates to a kind of high frequency electrodeless discharge lamp.
In CN1189241A, disclosed a kind of cell-shell that is coated with phosphor powder layer with air tight manner sealing inwall, amalgam and ionogenic blanketing gas are housed in the cell-shell, by bobbin coil is centered around on the magnetic core in the cavity, coil is connected with cable, and the electrodeless low voltage discharge lamp of band base heat conductive rod is housed in the magnetic core.This electrodeless low voltage discharge lamp is compared with the lamp described in the EP-A-162504 document, though simplified the fixing means of coil, also exists the high deficiency of complex structure and cost.
The purpose of this utility model is to provide a kind of coil fixing structure simple, the high frequency electrodeless discharge lamp that cost is low.
The utility model is achieved in that cell-shell is coated with the discharge cavity of phosphor powder layer with inwall of air tight manner sealing, be filled with ionogenic gas in the discharge cavity, discharge cavity comprise blast pipe, amalgam deposit the pipe and the inner chamber glass-tube, Auxiliary amalgam and main amalgam are housed in the discharge cavity, in the cavity that the inner chamber glass-tube is formed, with heat-resisting glue-line the varnished cloth bar in coil and the coil is wrapped on the magnetic core, coil is connected with cable, the heat conductive rod of band base is housed in the magnetic core, cell-shell is connected with lamp holder by weldering mud, and lamp holder is connected with securing member with the base of band heat conductive rod.Thereby realization the purpose of this utility model.
The utility model also can be realized like this: on the basis of above scheme, heat conductive rod is connected with magnetic core by thermal conductive insulation glue.
The utility model can also be realized like this: respectively on the basis of above two schemes, the other end of cable is connected with the Q9 joint.
Figure of description has been described this and has been used a novel embodiment surely.
Below describe embodiment of the present utility model in detail by accompanying drawing:
Cell-shell 1 is coated with the discharge cavity 3 of phosphor powder layer 2 with inwall of air tight manner sealing, fill argon gas in the discharge cavity 3, discharge cavity 3 comprises blast pipe 19, and amalgam is deposited pipe 20 and inner chamber glass-tube 21, on the broken pipe 21 of inner chamber Auxiliary amalgam 18 is housed, in amalgam is deposited pipe 20, main amalgam 15 is housed, and in the cavity 4 that inner chamber glass-tube 21 is formed, coil 7 is closely around magnetic core 5 surfaces of being with varnished cloth bar 6, and, make between its each circle all very close to each other with 6 tensions of varnished cloth bar.With heat-resisting glue-line 8 the varnished cloth bar in coil 7 and the coil 76 is wrapped up and is fixed on the magnetic core 5 then, coil 7 is connected with the cable 12 of band Q9 joint 13, cable 12 is fixed on the base by securing member 11, fixedly connected with magnetic core 5 by thermal conductive insulation glue 10 with the heat conductive rod 9 that red copper bar is made, cell-shell 1 is connected with lamp holder 16 by weldering mud 14, lamp holder 16 and the base 17 of being with heat conductive rod 9 connect with screw 22.Heat conductive rod 9 adopts interference fit to link together with base 17, to reduce contact heat resistance, guarantees the needs of heat radiation.
Use high frequency electrodeless discharge lamp described in the utility model, compared with prior art, have simple in structure, easy to process, thermal conductivity is strong, cost is low, cable is easy to connect and advantage such as solid and reliable.
