Abstract

The utility model provides a lucky picture illuminating lamp for the field of illuminating technology. The lucky picture illuminating lamp is characterized in that the root of a lamp bulb is provided with two sets of contacts, and the two sets of contacts are respectively connected with two sets of lamp filaments inside the lamp bulb through connecting lines; two sets of contacts are also arranged inside a lamp socket and are respectively matched with the two sets of contacts on the lamp bulb. Compared with an existing illuminating lamp, the lucky picture illuminating lamp is provided with two sets of contacts and two sets of lamp filaments; as a consequence, the service life of a lamp is extended, and waste is reduced.

Description

Two longevity illuminating lamps

The utility model belongs to lighting technical field, is a kind of pair of longevity illuminating lamp.

Existing illuminating lamp is divided into rib collar, bayonet socket and three kinds of forms of mouth hanging, and their filament all is one pair, in use, if tungsten filament is blown, just is provided with any reparation and recovery value, causes waste, and main is to bring inconvenience to live and work.

The purpose of this utility model provides a kind of illuminating lamp with two contacts and filament, thereby prolongs the useful life of lamp greatly, cuts the waste, and provides amenities for the people.

Technical solution adopted in the utility model is improved on the basis of original illuminating lamp, at the root of bulb two cover contacts is set, and two cover contacts are connected with two groups of filaments in the bulb by line respectively; In lamp socket, be provided with equally two the cover contacts, two the cover contacts respectively with bulb on two the cover the supporting uses in contact.

Because the utility model has been taked technique scheme, compares with existing illuminating lamp, has two contacts and filament, thereby prolongs the useful life of lamp greatly, cuts the waste, and provides amenities for the people.

Below in conjunction with accompanying drawing and example specific structural features of the present utility model is described further.

Fig. 1 represents the structural representation of the utility model screw-socket bulb.

Fig. 2 represents the root contact structure schematic diagram of the utility model screw-socket bulb.

Fig. 3 represents the root contact structure schematic diagram of mouth hanging bulb of the present utility model.

Fig. 4 represents the holder structure schematic diagram of mouth hanging bulb of the present utility model.

Fig. 5 represents bayonet cap structural representation of the present utility model.

As shown in Figure 1 and Figure 2, screw-socket bulb of the present utility model has outer screw socket 1 and vacuum glass cover 2, is provided with two

cover filaments

3 and 4 in cloche 2, and

filament

3 and 4 respectively lines 5 links to each other with 8 with two cover contacts 7 on the bulb root 6.As Fig. 2, contact 7 and 8 one are existing point-like main contacts, and one is the contact of paying of ring-type, and main contacts is higher than auxiliary contact, are provided with a bit equally in screw lamp holder, ring two cover contacts, and wherein bottom, center point-like contact is provided with the preloading spring seat.In use, the filament that at first uses main contacts to connect can continue precession with bulb if main filament blows, and auxiliary contact is inconsistent, auxiliary filament work.

As shown in Figure 3, Figure 4, relatively be provided with two

cover contacts

9 and 10 in the lamp socket of the utility model mouth hanging lamp, its four contacts are arranged in a crossed manner, and two cover contacts 11 and 12 with mouth hanging lamp end are complementary respectively.

As shown in Figure 5, the contact in the bayonet cap is identical with the mouth hanging lamp, offers a bayonet socket at original L shaped bayonet socket, becomes T shape bayonet socket.

Claims

1, a kind of pair of longevity illuminating lamp has bulb and lamp socket, it is characterized in that the root at bulb is provided with two cover contacts, and two cover contacts are connected with two groups of filaments in the bulb by line respectively; In lamp socket, be provided with equally two the cover contacts, two the cover contacts respectively with bulb on two the cover the supporting uses in contact.

2, a kind of pair of longevity illuminating lamp as claimed in claim 1, one is the ring-type auxiliary contact in order to decorate main contacts to it is characterized in that overlapping one of contact by two in the screw socket lamp lamp socket, wherein bottom, center point-like contact is provided with the preloading spring seat.
