Abstract
The utility model relates to a lamp tube, in particular to a double helical lamp tube, which is formed by spiral glass lamp tubes. The utility model is characterized in that two helical outlets are perpendicular to the central axis of the whole lamp tube. Applied to cylinder lamps and wall lamps, the utility model has the advantages of solving the problem of low light-emission efficiency of the ordinary double helical lamp tube, improving light-emission efficiency, and further saving energy resources.
Description
Technical field
The utility model relates to a kind of fluorescent tube, especially relates to a kind of double helix fluorescent tube.
Background technology
Nowadays, Down lamp on the market and wall lamp use the double helix fluorescent tube usually, and described double helix fluorescent tube is meant long glass lamp spiral surrounding as being similar to two screw threads is formed.As everyone knows: for Down lamp light fixture and wall lamp light fixture, the light-emitting area at built-in fluorescent tube top is big more, and the brightness of lamp is also just bright more; That is to say that in the lampshade of same volume size, the light-emitting area at fluorescent tube top is big more, lamp is just bright more.Double helix fluorescent tube in the market is owing to the restriction of fitting structure generally can only be provided with as among Fig. 2 and Fig. 4, its result just makes that the luminous of double helix fluorescent tube mainly is the fluorescent tube that relies on its that circle spiral bottom, other parts are little to luminous role, also just can not effectively utilize light fixture, thereby cause the waste of the energy.
The utility model content
Goal of the invention of the present utility model is to provide a kind of double helix fluorescent tube that is different from said structure, thereby can solve the technical problem that exists in the above-mentioned double helix fluorescent tube effectively.
Double helix fluorescent tube of the present utility model is formed by the glass tube spiral, it is characterized in that, two spiral outlet directions of described fluorescent tube are to be provided with like this: two spiral outlet directions of fluorescent tube are all vertical with the axis of whole fluorescent tube.
Double helix fluorescent tube of the present utility model, because two spiral outlet directions of described fluorescent tube are settings as described above, can be so that in the lampshade of same volume, the actual efficient lighting area on double helix fluorescent tube top obviously is greater than general double helix fluorescent tube, so the luminous efficiency of fluorescent tube is high more, so brightness is also just bright more.
Description of drawings
Fig. 1 is the front view of double helix fluorescent tube of the present utility model.
Fig. 2 is the front view of general double helix fluorescent tube.
Fig. 3 is that double helix fluorescent tube of the present utility model is arranged at the upward view within the lampshade.
Fig. 4 is that general double helix fluorescent tube is arranged at the upward view within the lampshade.
Embodiment
Nowadays, Down lamp on the market and wall lamp use the double helix fluorescent tube usually, and described double helix fluorescent tube is meant long glass lamp spiral surrounding as being similar to two screw threads is formed.As everyone knows: for Down lamp light fixture and wall lamp light fixture, the light-emitting area at built-in fluorescent tube top is big more, and the brightness of lamp is also just bright more; That is to say that in the lampshade of same volume size, the light-emitting area at fluorescent tube top is big more, lamp is just bright more.Double helix fluorescent tube in the market is owing to the restriction of fitting structure generally can only be provided with as among Fig. 2 and Fig. 4, its result just makes that the luminous of double helix fluorescent tube mainly is the fluorescent tube that relies on its that circle spiral bottom, other parts are little to luminous role, also just can not effectively utilize light fixture, thereby cause the waste of the energy.
As shown in figures 1 and 3, in Down lamp, described double helix fluorescent tube 2 is arranged among the lampshade 1, and described double helix fluorescent tube 23 is connected with the rectifier (not shown) that is positioned at double helix fluorescent tube top by going between.Identical with general in the market double helix fluorescent tube, double helix fluorescent tube in the present embodiment, be to form by the glass lamp helically coiling, different is, when producing described double helix fluorescent tube, two spiral outlet directions of described double helix fluorescent tube are to be provided with like this: two spiral outlet directions of fluorescent tube are all vertical with the axis of whole fluorescent tube.
In the present embodiment, because two spiral outlet directions of fluorescent tube are all vertical with the axis of whole fluorescent tube, with respect to double helix fluorescent tube general on the market, since in the present embodiment two outlets of double helix fluorescent tube unlike two fluorescent tubes outlets of double helix fluorescent tube like that parallel with the axis of fluorescent tube, thereby so can avoid the efficient lighting area on fluorescent tube top only too little by the fluorescent tube that encloses spiral, so in the lampshade of equal volume size, double helix fluorescent tube of the present utility model top just can have bigger efficient lighting area, so with respect to general double helix fluorescent tube, double helix fluorescent tube of the present utility model is because the actual effectively luminous area in fluorescent tube top is big, luminous efficiency is also just high, so brightness is also just bright more.
