In addition because the heat emission rate of aluminium is low, below 0.1, so that also be suppressed lowlyer to the heat emission of circuit substrate 13 sides by spatial portion 12c from the back side of spacer body 12.
By this, constitute a kind of thermal impact of lamp circuit that suppresses to control that luminous tube 11 is lit a lamp, improve the reliability of circuit member 13a, small-sized and realize the bulb type fluorescence lamp 10 of high outputization.
Here, said small-sized high outputization is 0.06W/ square centimeter (W/cm in the full value that consumes electric power/(globe holder surface area+case surface area)
2) remarkable especially under the above situation, and in fact as more than the 0.1W/ square centimeter, be the effective range of the small-sized high outputization of this example.The case surface area is the total of the spacer body 12 and the area of the part of the outside that is exposed to cover element 14.Here, the area that is exposed to the outside of the blade of a sword shape 12d of portion of spacer body 12 is preferably in 7～25 square centimeters the scope.As not enough 7cm
2, then can't expect radiating effect, as surpassing 25W/cm to the luminous tube more than the electric power 20W
2Then radiating effect is saturated, so can't obtain the effect that the material cost with spacer body 12 matches.
Below, to the bulb type fluorescence lamp of the above-mentioned the sort of formation structure as the ligthing paraphernalia of light source is described.
As shown in Figure 6,20 is the lighting tool of set following lamp formula on ceiling face X such as shop, is made of the main body case 21 that forms metal box-shaped that has peristome 21a below, the metal reflector 22 that is embedded among the peristome 21a.
At the central portion of the top panel of reflector 22, be provided with the lamp socket 23 of the lamp holder that is used to be screwed into bulb type fluorescence lamp.
On this lamp socket 23, be screwed into the lamp holder 15 of above-mentioned bulb type fluorescence lamp 10.By this, constitute the following lamp formula ligthing paraphernalia that is provided with bulb type fluorescence lamp 10, wherein this bulb type fluorescence lamp 10 has the spiral helicine luminous tube 11 of formation.
The ligthing paraphernalia of such formation, because the luminous intensity distribution of the bulb type fluorescence lamp of formation light source is approximate with the luminous intensity distribution of general incandescent lamp bulb, so can fully guarantee exposure, can access the utensil characteristic of the optical design that meets reflector near the light of the reflector the lamp socket that is disposed in the ligthing paraphernalia.
In this example, the blade of a sword shape 12d of portion of spacer body 12 is with the continuous annular of full Zhou Jinhang of the peripheral part that is formed on the plate-like face and be provided with, but also can be as shown in Figure 7, on the part of annular, form notch part 12h, and the 14b of sheet portion that notch part 12h is formed by an end opening portion that prolongs cover element 14 is stopped up.
And, also can be with the notch part 12h ' that on the part of annular, forms, the outstanding 16a of protrusion tab portion that forms stops up by one in the edge of opening portion of globe holder 16.
In addition, spacer body 12 can be made of the module of aluminium, but also can carry out pressure processing and constitute aluminium sheet.
The heat emission rate of aluminium is low, below 0.1, so can make the blade of a sword shape portion 12 of spacer body be exposed to the part of outside, forms for example concavo-convex or pears ginned cotton line, perhaps imposes white coating and the processing of white alumite and surface area is increased, and improves heat emission.
Particularly under the situation that imposes white coating and the processing of white alumite, as bulb type fluorescence lamp is lit a lamp by ligthing paraphernalia, then the reflectivity of the blade of a sword shape 12d of portion that is exposed to the outside of bulb strengthens, and can improve utensil efficient, and outward appearance, design also become well, also can improve commodity.
Also can adopt in by spacer body 12 and the formed spatial portion 12c of slider 13b, storage has the heat-barrier material that is made of for example mineral wool and vacuum magnetic bead etc., and partition makes heat can further not be transmitted to the structure of circuit substrate 13 and circuit member 13a from the heat of luminous tube 11.
In addition, also can adopt and globe holder 16 be formed slightly be cone shape and constitute, and on the pairing globe holder inwall in the side of luminous tube 11, form reflectance coating, and make formation transparent, promptly form the structure of the bulb type fluorescence lamp of reflection-type from the circular cone bottom surface of the radioactive department of the light of luminous tube 11.
Lamp holder is not limited to the E26 type, also can be Edison's lamp holders such as E17 type.
As utilize this example, owing to the metal of the spacer body 12 that will support luminous tube 11 by aluminium constitutes, and the blade of a sword shape 12d of portion that will be exposed to the outside is integrally formed, so the heat of luminous tube 11 is discharged to the outside effectively, and inhibition is to the thermal impact of lamp circuit, the reliability of circuit member 13a is improved, and be roughly the identical appearance size as the overall dimension of lamp and general incandescent lamp bulb, and the bulb type fluorescence lamp of small-sized and high outputization and constituting can provide a kind of bulb type fluorescence lamp that can replace with various incandescent lamp bulbs.
And, luminous tube 11, circuit substrate 13, cover element 14 and globe holder 16 as the main composition member of bulb type fluorescence lamp, on the spacer body 12 that all constitutes, be supported by metal, and spacer body 12 can not also have ultraviolet ray etc. to produce deterioration because of the heat from luminous tube, can support above-mentioned each member securely for a long time, long bulb type fluorescence lamp of a kind of life-span can be provided.
And, because spacer body 12 is integrally formed with the blade of a sword shape 12d of portion, thus conduction loss do not had from the heat of luminous tube, and be transmitted to the blade of a sword shape 12d of portion effectively as radiating part, and utilize outside air to cool off.
And spacer body 12 is made of the module of aluminium, so need not resemble the known example engineering of aluminium coat film on synthetic resin, makes to simplify the structure, and can not become the essential factor that cost rises.
So spacer body 12 constitutes light weight by aluminium, can not make the weight of bulb type fluorescence lamp become heavy.
In addition, the heat emission rate of aluminium is low, below 0.1, so can make from the back side of spacer body 12 heat emission to circuit substrate 13 sides by spatial portion 12c also be suppressed lowlyer.
In addition, the top formation aluminium of the formation plate-like face of spacer body 12 so this face forms the reflection of light face, reflects the light quilt on aluminium that radiates from luminous tube 11 downwards upward, can not produce optical loss.
Can't help aluminium making spacer body 12, and under the situation by known employed polybutylene terepthatlate (PBT) formation, cause is hot and ultraviolet from luminous tube, the top variable color of spacer body is a dark brown, the reflection of light rate is descended, but as utilize this example, so, the reflection of light rate is descended owing to be that aluminium constitutes nondiscolouring.
In addition, at spacer body is under the situation of synthetic resin, in long-term use, can occur forming gas because of the resin with variable color decomposes the deterioration thing that is produced, and be discharged in the globe holder and attached on the glass inner face, and the problem that the transmitance that makes light descends, but as utilize this example, so, the light transmission rate of globe holder is descended owing to be to constitute by aluminium not produce the deterioration thing.
As utilize this example, because circuit substrate 13 is by being supported on spacer body by the formed spacer body 13b of electric insulation member, so be to support under by slider 13b by the state of electric insulation at the spacer body 12 of metal and circuit substrate 13, circuit substrate 13 is also supported under by heat-insulating state with spacer body 12 simultaneously, and the temperature that can suppress circuit substrate more rises.
And, because the chase 14a that cover element 14 adopts annular, on the convex shaped part 12g of the blade of a sword shape 12d of portion of spacer body, just utilize the elasticity of synthetic resin and forcibly embed the structure of supporting, utilize the fixing together of screw so there is no need to resemble the known example, make assembling operation become simple.
In addition, blade of a sword shape portion outside and form the roughly continuous face of inclination upward above the cover cap can form the roughly continuous face with the contour approximation of general incandescent lamp bulb.
As utilize this example, owing to only utilize edge of opening portion and recess 12e to carry out chimeric simple structure with globe holder 16, and globe holder 16 is supported on spacer body 12, utilize the fixing together of screw so there is no need to resemble the known example, make assembling operation become simple.
More than preferable example of the present invention is illustrated, but the present invention is not limited to above-mentioned example, can carry out various design alterations in the scope that does not break away from main idea of the present invention.
