Abstract
The utility model provides an illuminating lamp which can continuously work through a spare filament after the original filament is burnt out. Two groups of filaments are arranged in the existing glass shell and are connected with a lamp head through lead wires to form three electrodes. The work of the spare filament can be controlled by a hand. The illuminating lamp has simple structure without changing the structure of the original lamp holder when in use, and is widely applied to various light sources. Because the utility model is added with the spare filament, the utilization ratio of materials can be raised, the service life of the illuminating lamp is extended, and the utility model has the significance of environmental protection and the function of two kinds of electric power for one illuminating lamp, and is the great innovation of the illuminating lamp.
Description
The utility model relates to a kind of filament energising and the light-emitting device of generation light, especially can be under the situation behind the filament blow, and the illuminating lamp of the stand-by lamp wire connection work of.
At present, known illuminating lamp structure is that two electrodes and one group of filament are formed, and filament adds after the appropriate voltage by thermal radiation or gas discharge and luminous.But, once behind the filament blow, whole illuminating lamp just can not re-use again, becomes rubbish, has both caused waste of material, causes environmental pollution again.
The purpose of this utility model provides a kind of illuminating lamp, and it can not only electrified light emitting, and behind first group of filament blow, the stand-by lamp wire connection can continue luminous.
The purpose of this utility model is achieved in that at the glass shell internal fixation two groups of filaments, one end of two groups of filaments is connected together and draw outside the glass shell by glass supporter with three lead-in wires respectively at other two ends, form three electrodes outside, and a simple and easy switch is set, control the work of standby filament.When giving by lamp socket after wherein one group of filament adds voltage, the illuminating lamp that has standby filament is luminous, behind the filament blow, control switch is connected for a certain reason, and standby filament work just can reach and follow luminous purpose.
Owing to adopt such scheme; can behind first group of filament blow, connect backup electrode easily with hand; the stand-by lamp wire connection to continue luminous; so just improved raw-material utilance; prolonged the useful life of the illuminating lamp that has standby filament; and the meaning of environmental protection is arranged, and also two groups of filaments can be worked simultaneously, make the illuminating lamp that has standby filament that the function of two kinds of electrical power be arranged.When using the utility model, need not change original lamp socket, easy to use.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is the vertical section structural map of first embodiment of the utility model (fluorescent tube).
Fig. 3 is that the A of Fig. 2 is to the filament plane graph.

Among the figure: 1. public electrode 1A. public electrode 2. primary electrode 2A. primary electrodes, 3. backup electrode 3A. backup electrodes, 4. insulating spacers 5. wire rack mount 6. insulation fixing glue 7. sealing device head 8. exhaust outlets 9. glass supporters 10. standby filament 11. former filament 12. glass shells 13. quartz tube 14. insulation stators 15. glass shells 16. tube lamp holder caps 17. mercury vapour 18. fluorescent material of bleeding that go between that go between that go between
In Fig. 1, public electrode (1) connects together by the end of public electrode lead-in wire (1A) with standby filament (10), former filament (11).The other end of former filament (11) is connected on the primary electrode (2) by primary electrode lead-in wire (2A), the other end of standby filament (10) is connected on by backup electrode lead-in wire (3A) that standby insulating spacer (4) separates between the backup electrode (3), insulating spacer (4) must guarantee fine insulation between primary electrode (2) and the backup electrode (3), and unfixing dead, need the time spent to take away easily primary electrode (2) and backup electrode (3) are connected with hand.
In Fig. 2, fluorescent tube two header structures are symmetry fully, and wherein the structure of an end is: in tube lamp holder cap (16), be fixed with insulation stator (14), fixing public electrode (1), primary electrode (2) and backup electrode (3) on the insulation stator (14).Wherein public electrode (1) and primary electrode (2) are gone up outstanding certain altitude at insulation stator (14), and they can well be contacted with lamp socket.Do not separate with fixing dead insulating spacer (4) between primary electrode (2) and backup electrode (3), can take away easily with hand when needing, primary electrode (2) and backup electrode (3) are connected.Backup electrode (3) is outstanding a small amount of, is positioned at the center.Public electrode (1) is introduced in the glass shell (15) from glass supporter (9) by public electrode lead-in wire (1A), links together with an end of former filament (11), standby filament (10).One end of former filament (11) is drawn from glass supporter (9) by primary electrode lead-in wire (2A), and the other end that is connected on the last standby filament (10) of primary electrode (2) draws silk (3A) by backup electrode draws from glass supporter (9), is connected on the backup electrode (3).Former filament (11) and standby filament (10) form " one " line style respectively, and it is orthogonal to constitute antarafacial " straight line ", and suitable distance is arranged between them, and standby filament (10) is last, and former filament (11) is following.Quartz tube (13) is a tubular, and two open ends, slightly larger in diameter are in filament, and each contact conductor penetrates quartz tube (13) wall half-turn, play the fixedly effect of quartz tube (13), the length of quartz tube (13) is slightly larger than primary electrode lead-in wire (2A) length in glass lamp.Tube lamp holder cap (16) and glass shell (15) insulation fixing glue (6) link together, and the air in the glass shell (15) can be taken away from exhaust outlet during fabrication, charges into mercury vapour (17) then, seals in the sealing device head of bleeding (7) again.
In another embodiment shown in Figure 5, the insulation fixing glue (6) of fixed electrode is fixed together public electrode (1), primary electrode (2), backup electrode (3), form lamp holder, mutually insulated between them, wherein, isolate with fixing dead insulating spacer (4) between primary electrode (2) and the backup electrode (3), can insulating spacer (4) be taken away easily with hand when needing and make primary electrode (2) and backup electrode (3) connection.Public electrode (1) is introduced in the glass shell (15) from glass supporter (9) by public electrode lead-in wire (1A), links together with an end of former filament (11), standby filament (10).The other end of former filament (11) is drawn from glass supporter (9) by primary electrode lead-in wire (2A), is connected on the primary electrode (2).The other end of standby filament (10) is drawn from glass supporter (9) by backup electrode lead-in wire (3A), is connected on the backup electrode (3).The plane that plane that former filament (11) constitutes and stand-by lamp (10) constitute is parallel to each other, and suitable distance is arranged, insulation fixing glue (6) links together glass shell (12) and lamp holder, and the interior air of glass shell (12) can be taken away from exhaust outlet during fabrication, seals (7) and seals bleeding.
