Implement the good form of amount of the present invention
Below, utilize accompanying drawing that example of the present invention is described.
(example 1)
The structural map of in Fig. 1, having represented the invention process form 1.
In Fig. 1, two tube ends 5 of the glass tube 2 of inner coating fluorophor 1 (Fig. 1 only represents of left side) have to make to be gone up to the side-prominent hermetic unit 50 in inside.Disposing electrode cable 4, it extends in the pipe through hermetic unit 50 and from the outside.And, install sparking electrode 3 in the interior extremity of this electrode cable 4.This electrode cable 4 is when supporting sparking electrode 3, also from managing outside transmission power to the inner electrode 3 of pipe.
On the electrode cable 4 between hermetic unit 50 and the sparking electrode 3, be provided with diffuse reflector 6 again.Enclose metallic vapour and rare gas in this inside and constitute fluorescent lamp.
This diffuse reflector 6 do not have conductivity, when making on the material of high temperature as glass or ceramic wafer and ability fluorescent lamp, coating BaSo
4And TiO
3Constitute Deng material from visible wavelength to the ultraviolet wavelength zone, that have high reflectance.
The radiation that generates owing to the discharge that in glass tube 2, takes place and because this radiation, the light that fluorophor 1 sends is in the pipe internal reflection, and wherein pass through this diffuse reflector 6 towards the radiation of tube end and the part of light, be reflected on glass tube 2 private sides, luminous flux or irradiation luminous flux are increased.
(example 2)
Fig. 2 is the structure of expression the invention process form 2.
Among Fig. 2, two tube ends 5 (Fig. 2 only represents of left side) that apply the glass tube 2 of fluorophor 1 in inside have to make to be gone up to the side-prominent hermetic unit 50 in inside.Disposing electrode cable 4, it extends in the pipe through hermetic unit 50 and from the outside.And, install sparking electrode 3 in the interior extremity of this electrode cable 4.This electrode cable 4 also send electricity to the inner electrode 3 of pipe from managing the outside when supporting sparking electrode 3.
On the electrode cable 4 between hermetic unit 50 and the sparking electrode 3, be provided with fluorescent plate 7 again.Enclose metallic vapour and rare gas in this inside and constitute fluorescent lamp.
Utilization from the discharge of sparking electrode 3 to the wavelength of the direction radiation of tube end 5 for ultra-violet radiation 254nm and 185nm etc., the activating fluorescent body, make this fluorescent plate 6 luminous.Again, the discharge that utilization takes place in the glass tube 2 and radiation that produces makes the light-emitting phosphor that is coated on glass tube 2 tube walls, and during light-emitting phosphor, fluorescent plate 7 will increase luminous flux or radiant flux towards the described glass tube of being reflected to of tube end 5 inside thus.
In fact, on the electrode cable 4 of FL20SSEXD fluorescent lamp, made a lamp that has installed the fluorescent plate 7 that applies same EXD usefulness fluorophor.This moment, fluorescent plate 7 was fixed on from the position of sparking electrode 3 10～15mm on tube end 5 directions.
Side by side make the lamp (existing lamp) be provided with the lamp of fluorescent plate 7 and do not have fluorescent plate, their characteristic is compared during for 18W in the electrical power of lamp, then the tube voltage of lamp and tube current are almost equal, obtain luminous flux and increase 2.3% such result approximately.
(example 3)
To describing of example 3 of the present invention.The structure of example 3 be with example 2 structure at the intentional different structure of the fluorophor of the fluorophor 1 of coating and coating on fluorescent plate 7 on 2 on the glass tube.
FL20SSEXD fluorescent lamp shown in the example 2 is the fluorescent lamp of three-wavelength district light emitting-type, mixes being coated with the fluorophor of apposition more than 3 kinds in this lamp.Therefore, for the fluorescent lamp of same mixture ratio,, then can easily adjust all colors of lamp by repeatedly changing the fluorophor of fluorescent plate 7.
(example 4)
Fig. 4 is an example 4 of the present invention.Pipe end enclosure portion 50 its part 50b towards sparking electrode 3 of tube end 5 are for discoid in this example.This discoid part 50b is bigger than the body of hermetic unit 50a.
(example 3)
Again, in the example of Fig. 4, the size of this discoid part 50b almost is identical with the size of glass tube 2 internal cross section.
Moreover, on the surface of this discoid part 50b, make to have formed the material of diffuse reflector illustrated in the example 1,2 and the material of fluorescent plate.Utilize this part 50b, as implement form 1,2 described, can Enhanced Radiation Reduced Blast flux and luminous flux.
Secondly, describe for the method that forms so discoid part 50b.
Among Fig. 5, at first, make the parts that form tube end 5.That is, prepare the glass tube 20 (a) of a both ends open.The two ends of this glass tube 20 are expanded into taper shape (b).In this glass tube 20, insert thin glass tube 21 and electrode cable material 22 (c).Like this, these glass tube 20 1 side sides connect flat model 23, and (central authorities exist the hole of perforation, among this, be inserted with the termination of electrode cable material 22), and the middle body at glass tube 20 is compressed by the model 24 of other shape, the central authorities of glass tube 20 are dwindled and fuses on thin glass tube 21.Simultaneously from the other end send into air with the end sealer of thin glass tube 21 this moment, thereby form aperture 25 in the centre.Its result is to have formed discoid 26 in the part that contacts with model 23.After this, at the end device sparking electrode of electrode cable 22.
At the portion's material that makes like this and form tube end 5 is end by the glass tube of the fluorescent lamp of other making, makes sparking electrode 3 inboard and embed, weld.Like this, the fluorescent lamp of cost of manufacture example 4.
Moreover because the shape of above-mentioned model 23 can be various kinds, the shape that therefore can access discoid part 26 also is a various kinds.
Moreover, reflecting plate of the present invention, fluorescent lamp, towards the shape of sparking electrode side part, be not limited in the example illustrated, it also can be different shape shown in Figure 6, main is, if prevent with towards the radiation of tube end 5 and light component intactly towards tube end 5 and be absorbed and just can.
(a) of Fig. 6 is the type that forms a plurality of projectioies from the teeth outwards, (b) is to form a plurality of concavo-convex types, and figure (c) is the type of concave.
Industrial applicability
According to above invention, by the characteristic of electricity same, can improve fluorescent lamp luminous flux, Can realize the improvement of lamp efficient.
