Abstract
The utility model relates to a two position screw socket bulb, which still fundamentally maintain the shape and the structure of the existing incandescent screw socket bulbs. On the basis of the existing incandescent screw socket bulb, the utility model is formed by adding a branch line and a tungsten filament which is arranged on the two different planes of the bulb. The utility model has the outstanding advantages that the service life of the bulb is prolonged; the structure is simple; the fabrication is easy.
Description
The utility model is to belong to a kind of illumination screw-socket bulb.
Generally popular in the market screw-socket bulb is for a tungsten filament, and after this tungsten filament blew, this bulb just can not re-use, so useful life is short, the manufactured materials waste is bigger, and use value is low, not too is subjected to liking of people.
The purpose of this utility model is for a kind of dibit screw-socket bulb that can prolong bulb service life is provided, and simple in structure, makes easily.
Technical solution of the present utility model is: it has still kept the shape and structure of existing incandescent screw-socket bulb substantially, and design increases a tungsten filament on the basis of existing incandescent screw-socket bulb, places two Different Plane in the lamp, and design increases a branch line.And form this new incandescent screw-socket bulb, and reached a bulb can support two purposes that bulb is used, make prolong one times the useful life of bulb.
Accompanying drawing has been described an embodiment of the present utility model.
Accompanying drawing is to be three-dimensional shape structural representation of the present utility model
1-crown top of burner 2-contact 1 3-contact 2
4-main contact 5-left side branch line 6-main line
The right branch line 8-of 7-stem stem 9-goes up tungsten filament
10.-tungsten filament 12-lampshade under the filament 11-
Below in conjunction with accompanying drawing the utility model is described in detail.It has still kept the shape of existing screw-socket bulb substantially the incandescent screw-socket bulb that is proposed, promptly form by the crown top of burner, wick and lampshade three parts, itself and existing crown top of burner difference are, design has contact 1 (2) and the contact 2 (3) that contacts with power supply on the limit of the crown top of burner (1) top end face, design one main contact (4) on the arc lower limit, and the position of contact 1 (2) and contact 2 (3).Be to become an angle of 90 degrees with the crown top of burner (1) center.Wick is made up of stem stem (8), left branch line (5), main line (6), right branch line (7), last tungsten filament (9), filament (10) and following tungsten filament (11), at itself and existing difference be, be designed to three lines in the stem stem (8), be left branch line (5), main line (6) and right branch line (7), the lower end design is equipped with tungsten filament (9) and following tungsten filament (11).
Left branch line described in the utility model (5), main line (6) and right branch line (7), its left branch line (5) upper end links to each other with contact 1 (2), the lower end links to each other with last tungsten filament (9), link to each other with contact 2 (3) in its right branch line (7) upper end, the lower end links to each other with following tungsten filament (11), again in its main line (6) upper end with outside main contact (4) links to each other, the lower end links to each other with upper and lower tungsten filament (9) (11) other end that does not connect.
The tungsten filament (9) of going up described in the utility model is to be inclined in an interior plane of lamp by filament (10), and tungsten filament (11) still is flat on another interior plane of lamp by filament (10) under it.
During use bulb is screwed in the lamp holder, allow contact 2 (3) switch on, make down tungsten filament (11) luminous.If this root tungsten filament blows, as long as bulb is continued the rotation an angle of 90 degrees, can allow contact 1 (2) switch on, make tungsten filament (9) electrified light emitting.
The maximum characteristics of the utility model are the service life of having improved bulb, and simple in structure, easy to manufacture, and result of use is good, remarkable in economical benefits.
