Embodiment

In order that technical solutions of the utility model are clearer, now the present invention is done further in detail with accompanying drawing in conjunction with the embodiments Describe in detail bright：

With reference to Fig. 1-4, a kind of Double-tube lamp, including light source board 3, two periosteums 1 and two fluorescent tubes 2；

Two periosteums 1 are alongst placed in parallel, and tangent company is realized in its opposite side by hot melt Connect；The periosteum 1 alongst has the cavity 11 for housing the fluorescent tube 2, and the fluorescent tube 2, which is inserted after the cavity 11, to be led to Pyrocondensation is crossed so that the periosteum 1 is coated on the sidewall surfaces of the fluorescent tube 2.This makes it possible to cause two fluorescent tubes closely to connect, Production process is extremely simple, and cost is also very low.

The two ends of the cavity 11 and fluorescent tube 2 are openend；The side wall of described two periosteums 1 is connected along radial direction, So that length direction of described two periosteums 1 along periosteum 1 is symmetrical；The light source board 3 includes flexible base board 31 and set The LED/light source 32 and drive circuit 33 being placed on flexible base board 31, the flexible base board 31 being partially disposed in equipped with LED/light source 32 In one of fluorescent tube 2, the openend of the fluorescent tube 2 is stretched out and by curved in part of the flexible base board 31 equipped with drive circuit 33 Inserted after folding in another fluorescent tube 2.So it is achieved that the discrete setting of drive circuit 33 and LED/light source 32, drive circuit 33 The heat that the heat and LED/light source 32 sent is sent just can respectively be radiated by two fluorescent tubes 2, and radiating effect compares It is good, it is covered with LED/light source 32 on the flexible base board 31 in a fluorescent tube 2 while can also realize, outgoing light homogeneity and brightness are all compared Preferably.

The part of drive circuit 33 includes drive terminal 331, when the drive circuit 33 is placed in the fluorescent tube 2, The part of drive terminal 331 is exposed to outside the fluorescent tube 2 by the openend, so as to realize the electrical connection with extraneous power supply.

In the present embodiment, in addition to two plugs 4, it, which is installed in the openend of the fluorescent tube 2, the plug 4, has Shell fragment 41, the drive terminal 331 is inserted forms electrical connection therewith in the shell fragment 41.

Further, the plug 4 includes a housing 42, and the housing 42 has two towards the side of the openend There is the shell fragment 41 respectively in the individual accommodating chamber 43 with the openend grafting, each accommodating chamber 43, so no matter plug with Which kind of direction and the grafting of fluorescent tube 2, can cause plug 4 to be electrically connected with drive terminal 331.

The one end of the housing 42 away from the accommodating chamber 43, with the corresponding position of one of accommodating chamber 43 be provided with along Convex boss 421, the groove 422 axially concaved is provided with another corresponding position of accommodating chamber 43 axially outward.Institute The bottom for stating groove 422 is axially outwardly formed two contact pins 423, and the end face of the boss 421 is axially inwardly formed Two jacks 424；When the boss 421 is inserted in the groove 422, shape in the correspondence of contact pin 423 insertion jack 424 Into electrical connection.After so setting, as long as two plugs 4 is in opposite direction, it becomes possible to so that the boss of groove 422 of two plugs 421 correspond to grafting respectively, and utilize contact pin 423 and the formation electrical connection of jack 424.Therefore, more piece Double-tube lamp just can be by stifled First 4 formation is connected in series, as long as after one of Double-tube lamp is electrically connected with city, remaining Double-tube lamp also can be lighted normally.

Two accommodating chambers 43 are connected described in the present embodiment, the flexibility that its connectivity part is formed between accommodating two fluorescent tubes 2 Substrate 31 allows bit space.So that the flexible base board after bending also has independent space to be laid in fluorescent tube 2.

Finally, in the present embodiment in order to realize the installation of Double-tube lamp, in addition to buckle 5；The buckle 5 includes an elasticity and embraced Folder 51, its armful is sandwiched in the periphery of one of fluorescent tube 2；The buckle 5 also has a peace away from one end that the elasticity embraces folder 51 Hole 52 is filled, by fixture, such as nail or bolt, inserts after the mounting hole 52 and the Double-tube lamp is fixed with fixture Install.

It is described above, only the utility model preferably embodiment, but design concept of the present utility model is not This is confined to, any one skilled in the art utilizes this design in the technical scope that the utility model is disclosed The change of unsubstantiality is carried out to the utility model, belongs to invade the behavior of the utility model protection domain.
