In addition, below so-called external diameter of pipe Dao be meant the diameter of curved glass pipe 2, ring outer diameter D a is meant from the bearing of trend that curls up axle and observes luminous tube 1 diameter when whole.
＜2. checking 〉
Here, the inventor replaces the lamp 20 of usefulness for above-mentioned general bulb 60W, explore, studied face shaping is remained with general bulb 60W roughly equal in, can realize the means of the further improvement of lamp efficiency eta.
Particularly, more than 1% target lamp efficient is compared improvement with the value in the past (67.5lm/W) of above-mentioned lamp in the past 120 (Fig. 5).
Here, being made as more than 1%, is because consider the inhomogeneous error of bringing that the characteristic of each product is arranged when luminous tube 1 reality is made as product.
As a result, as the feature of the configuration aspects of the lamp 20 of present embodiment, find that following two conditions are effective means for the increase of lamp efficiency eta.
That is, at first, condition (1) is that (the clearance G d each other of 2a～2e) is set in respect to the ratio Gd/Dao of this outer diameter D ao in 0.2～0.6 the scope for pipe curved glass pipe 2, that produce along external diameter of pipe Dao direction that will form the double-layer spiral shape of luminous tube 1.
Condition (2) be further in the luminous tube 1 of condition (1), the bore Dai of the curved glass pipe of double-layer spiral shape is set in the scope of 4.0～7.0mm respectively and the tube wall we (amassing the value defined that π DaiLe removes by the pipe internal surface corresponding to interelectrode distance Le with manage input) that loads is set in 0.10W/cm
2In the following scope.
Below, describe successively setting the above-mentioned condition (1) in the lamp 20 and the reason of (2) and the effect that obtains thus.

The lamp efficient of the ratio Gd/Dao of above-mentioned lamp 120 in the past being brought up to 0.4 structure is 70.5lm/W.
Found that, as shown in Figure 4, by being set in 0.10W/cm in the scope that respectively the bore Dai of curved glass pipe 2 is set in 4.0～7.0mm and with the tube wall we that loads
2In the following scope, bringing up to ratio Gd/Dao with above-mentioned lamp 120 in the past that 0.4 o'clock lamp efficient (70.5lm/W) compares can be with lamp improved efficiency 7～25%.
As a result, bore Dai and tube wall load we is with respect to 7.4mm and 0.12W/cm in the above-mentioned lamp in the past 120
2Be set in 4.0～7.0mm and 0.10W/cm
2In the above small range.Thus, be to compare in 0.11 o'clock to realize about 8～31% improvement as the efficiency eta of the lamp 20 of present embodiment and ratio Gd/Dao in the above-mentioned lamp in the past 120.
＜3. preproduction 〉
At last,, manufactured experimently the lamp 20 of structure, measured its each characteristic with above-mentioned present embodiment in order to reaffirm effect of the present invention.In the case, at first, the lamp input is set at 10W, here, the circuit efficiency of electronic stabilizer 23 is 90%, thereby is set to 9W to the pipe input of luminous tube 1.
Then, the geomery of luminous tube 1 is set at 7.5mm with the external diameter of pipe Dao of main portion respectively, and Dai is set at 6.5mm with bore, and interelectrode distance Le is set at 480mm, and thus, the tube wall of luminous tube 10 load we is set to about 0.09W/cm
2In addition, respectively the clearance G d of the curved glass pipe 2 of double-layer spiral shape is set at 3.0mm, ratio Gd/Dao is set at 0.4, will manages volume number of plies N and be set at about 5.3 weeks, will encircle outer diameter D a and be set at 36.5mm also will manage total length La is set at 60～75mm (for example about 66mm).And the lamp face shaping is set at 55mm with the outer diameter D o of outer tube bulb 122, and Lo is set at 110mm with the lamp total length.
