The concrete structure of the bulb type fluorophor lamp 1 of Gou Chenging is as described below like this.Promptly, the maximum outside diameter φ 1 of bulb 6 is 55mm, the luminous tube maximum outside diameter of luminous tube 4 (spiral external diameter) φ 2 is 30.5mm, the external diameter φ 3 of the opening mounting end 3b of cover 3 is 39mm, the external diameter φ 4 of the glass tube 2a of luminous tube 4 is 8.65mm, height from the top outer surface of bulb 6 to the aperture 2c outer surface of lamp holder 2 (axial length: lamp is long) h1 is 109mm, the height of spiral luminous tube 4 (axial length) h2 is 77mm, height (axial length) h3 of cover 3 is 14mm, pair of electrodes 4b, discharge Lu Changwei 300～500mm between the 4c, in addition, the external diameter φ 5 of lamp holder 2 is 26mm, is about 1.17 times of luminous tube maximum outside diameter φ 2 (30.5mm).
So, according to this bulb type fluorescence lamp 1, the general lighting outward appearance of bulb that can obtain 60W (rated power of the lamp) type of the long 110mm of lamp.
In addition, because luminous tube 4 is that spirality and discharge road are longer, thereby luminous efficiency height, because height (axial length) h3 of non-luminous cover 3 is 14mm, be 12.8% of the long h1 of lamp (109mm), very short, luminous efficiency is improved, and can obtain with general lighting with the approximate outward appearance of lighting a lamp of bulb.
And, because electron tube external diameter φ 4 is the thin footpath of 8.65mm, thus can increase the spiral number of turns, and the road length of will discharging do longer, thereby can further improve luminous efficiency.
Fig. 4 is the longitudinal section of the bulb type fluorescence lamp 1A of the 2nd execution mode of the present invention.This bulb type fluorescence lamp 1A has following feature with respect to Fig. 1～related bulb type fluorescence lamp 1 of the 1st execution mode shown in Figure 3: luminous tube maximum outside diameter φ 2a is that the external diameter φ 3a of 35.5mm, cover 3 openend installation portion 3b is that the height h3a of 43mm, cover 3 is 25mm.In addition, cover 3 is formed by the translucent resin moulding.Thus, can make luminous near the position of the luminous tube 4 of electrode 4b, 4c by outwards radiation of cover 3.Structure in addition is identical with the bulb type fluorescence lamp 1 that size and the 1st execution mode relate to.
Because the apparent size of this bulb type fluorescence lamp 1A is also approximate with the apparent size of bulb with general lighting, thus can obtain with general lighting with the approximate outward appearance of the outward appearance of bulb with light a lamp outward appearance.
In addition, owing to be luminous tube maximum outside diameter φ 2a bigger than the maximum outside diameter of above-mentioned bulb type fluorescence lamp 1, so the mould molding of luminous tube 4 becomes easily, the discharge road is long also elongated, thereby can improve luminous efficiency.
Fig. 5 is the longitudinal section of the bulb type fluorescence lamp 1B of the 3rd execution mode of the present invention.This bulb type fluorescence lamp 1B has following feature with respect to bulb type fluorescence lamp 1A shown in Figure 4: make the Lower Half 4e Fig. 5 of lamp holder 2 sides from roughly five equilibrium (1/2) position of the height h2 direction of luminous tube 4, with the undergauge of bottom among the figure of bulb 6 and cover 3 accordingly to lamp holder 2 sides undergauge gradually, make the pair of electrodes hermetic terminal horizontal and become terminal.Other structure in addition is identical with the related bulb type fluorescence lamp 1A of size and the 2nd execution mode.
Therefore and since the apparent size of this bulb type fluorescence lamp 1B also with above-mentioned bulb type fluorescence lamp 1A in the same manner, approximate with general lighting with the apparent size of bulb, thus can obtain with general lighting with the bulb approximate outward appearance and the outward appearance of lighting a lamp.
In addition, because the Lower Half 4e that contains the pair of electrodes hermetic terminal of luminous tube 4 is to lamp holder 2 one sides undergauge gradually, so the undergauge end that can in the cover 3 of the transparent resin of making by polycarbonate resin etc., deeper insert this luminous tube 4, and make near its bottom that extends to lamp holder 2.
Thus, the discharge road that can increase luminous tube 4 is long, thereby can improve luminous efficiency.In addition because to can be luminous near the bottom of lamp holder 2, so can be further near the outward appearance of lighting a lamp of electric consumption on lighting bulb.
And, also can make accordingly and cover 3 lamp holder 2 side end undergauges with the undergauge Lower Half 4e of luminous tube 4.In this case, the receiving space that is housed in the ignition device 7 of cover in 3 becomes narrow, like this, also can use a plurality of main switch elements of the phase inverter that for example will be used for lamp circuit to be housed in the box and the Small electronic component that forms etc.
Fig. 6 is the longitudinal section of the bulb type fluorescence lamp 1C of the 4th execution mode of the present invention.This bulb type fluorescence lamp 1C has following feature with respect to bulb type fluorescence lamp 1B shown in Figure 5: make the first half 4f than top among the more close figure of the 4g of maximum outside diameter portion of luminous tube 4, with the undergauge of the inner surface of the top ends 6B1 of bulb 6B undergauge gradually accordingly, and with first half 4f and Lower Half 4e undergauge simultaneously, and bulb 6B is divided into for example two parts 6B2,6B3.Other structure in addition is identical with bulb type fluorescence lamp 1B shown in Figure 5 with size.
According to this bulb type fluorescence lamp 1C, owing to make the spiral external diameter of first half 4f top Ca, among Fig. 5 of the return portion 4d that contains luminous tube 4 ground that matches with the undergauge inner peripheral surface of the top ends 6B1 of bulb 6B, from the luminous tube maximum outside diameter 4g of portion to return portion 4d undergauge gradually, so the top Ca outer surface that can make return portion 4d is as much as possible near the inner surface of the top ends 6B1 of bulb 6B, thereby can further improve luminous tube height h2.Thus, the discharge road that can increase luminous tube 4 is long, thereby can improve luminous efficiency.
In addition, owing to increase the external diameter of the 4g of maximum outside diameter portion of luminous tube 4, can further increase the long and raising luminous efficiency in discharge road with the maximum outside diameter φ 1 of bulb 6B with matching.
And, bulb 6B, with the central shaft of the coaxial bulb 6B of the central shaft O of luminous tube 4 on, vertically be divided into left side 6B2 and right-hand part 6B3 among Fig. 6.
That is, this bulb 6B image pattern 1, Fig. 4, when bulb 6 shown in Figure 5 is formed by the non-integral body of cutting apart like that, the external diameter of the 4g of maximum outside diameter portion of luminous tube 4 is bigger than the open end 6a of bulb 6, so can not be from this open end 6a insertion luminous tube 4.
But, because this bulb 6B is divided into left and right half 6B2 of, 6B3 on the axle therein, so after uprightly being arranged on luminous tube 4 on the support 5 respectively, the outside of this luminous tube 4 is covered by left and right half 6B2 of, the 6B3 of bulb 6B respectively from its side, and should left and right half 6B2 of, 6B3 be installed on the cover 3 with the state of outstanding combination integratedly.
Afterwards, omit the illustrated bag of reservation shape shape heat shrink films,, can make left and right half 6B2 of, the 6B3 combination integratedly of bulb 6B by making this heat shrink films thermal contraction in the outer surface covering of bulb 6B.
In addition, according to this bulb type fluorescence lamp 1C, owing to top Ca, carry out undergauge, can make the 4g of maximum outside diameter portion of luminous tube 4 cooperate the maximum outside diameter portion inner surface of bulb 6B to carry out hole enlargement with the undergauge inner surface of bulb 6B from the 4g of maximum outside diameter portion of luminous tube 4 with matching.Thus, can improve the luminous efficiency of luminous tube 4.
And bulb 6B can be divided into two parts along transverse direction (horizontal direction).In this case, shown in the dotted line among Fig. 6, can be with the center line of the maximum outside diameter portion of luminous tube 4 as cut-off rule d and above-below direction in the drawings is divided into two parts 6B2,6B3.Thus, cut-off rule d is the center line of the maximum outside diameter portion of luminous tube 4, so can use down the integral body that a pair of bulb 6B2,6B3 cover luminous tube 4.
Fig. 7 is the general configuration figure of the lighting device 11 of the 5th execution mode of the present invention.This lighting device 11 is the lighting device of the small spotlight of irradiation etc. downwards in the ceiling for example, and has ligthing paraphernalia main body 12.Lamp socket 13 and reflector 14 are installed in this ligthing paraphernalia main body 12, and the lamp holder 2 of any one among above-mentioned bulb type fluorescence lamp 1, the 1A～1C is installed on the lamp socket 13 by being threaded.
And, the present invention is not limited to the size of above-mentioned each bulb type fluorescence lamp 1,1A～1C, for example luminous tube maximum outside diameter φ 2 25～36mm, its electron tube external diameter φ 4 at 7～9mm, luminous tube height h2 in 65～85mm, discharge road length each scope at 400～600mm, also can reach and these bulb type fluorescence lamps 1, the roughly the same action effect of 1A～1C.In addition, cover 3 also can be formed by transparent resin.Thus, can make luminous this translucent cover that sees through carry out luminous from luminous tube 4.So can the nearly all part of other except that lamp holder can be luminous with bulb as general lighting.Thus, can obtain general lighting with the outward appearance of bulb and the outward appearance of lighting a lamp.
