In addition, in lamp device 10, lampshade 15 region accounts for more than 55% of lamp total length on lamp axle z direction, is preferably more than 60%.
Then, the effect of present embodiment is described.
When using lamp device 10, power supply 18 is connected to the incandescent lamp bulb lamp socket of the general illumination of lighting device.If alternating electromotive force is supplied to lamp device 10 by lamp socket, then power supply unit 17 converts alternating electromotive force to predetermined direct current power and is supplied to light-emitting component 31.Thus, make light-emitting component 31 luminous, radiate bright dipping from illuminating part 34.
The light radiated from illuminating part 34 incides light-guiding pillar 42 from the plane of incidence 46, and guide-lighting towards light radioactive department 47 in light-guiding pillar 42.The guide-lighting light to light radioactive department 47 is reflected by the reflectance coating 45 of recess 44 and penetrates from the end face of the end side of the cylinder of light-guiding pillar 42 or light-guiding pillar 42, and the end face (i.e. front end face 48) of end side from light-guiding pillar 42 directly penetrates.Therefore, extreme direction before horizontal, the light-guiding pillar 42 that can intersect to the axis with light-guiding pillar 42 from light radioactive department 47, the wider direction radiating light in oblique direction is rolled from light-guiding pillar 42 to framework 11.The light transmission lampshade 15 radiated from light radioactive department 47 is irradiated to lighting space.
Further, lamp device 10, due to light radioactive department 47 radiating light from light-guiding pillar 42, thus can reproduce the sense of glittering as lighted transparent incandescent lamp bulb.
The center of the maximum outside diameter portion D of lampshade 15 is configured at due to light radioactive department 47, thus from light radioactive department 47 to radiation direction, the light of radiation impinges perpendicularly on lampshade 15 thus is easy to through lampshade 15, can suppress to produce unnecessary light reflection at the inner surface of lampshade 15, therefore, it is possible to improve sense of glittering, and can improve towards the light output efficiency outside lampshade 15.
In addition, if lamp device 10 to be arranged to the size approximate with the incandescent lamp bulb of general illumination, then in order to light radioactive department 47 being configured at the center of the maximum outside diameter portion D of lampshade 15 and the length of light-guiding pillar 42 that the needs scope at 35 ~ 45mm.
Further, the diameter d of light-guiding pillar 42 is in the scope of 2 ~ 9mm.If the diameter d of light-guiding pillar 42 is less than 2mm, then the light of illuminating part 34 is difficult to incide light-guiding pillar 42, thus efficiency is declined, and if the diameter d of light-guiding pillar 42 is greater than 9mm, then light radioactive department 47 becomes large, thus makes sense reduction of glittering.
Further, as shown in Figure 4, opening diameter (diameter of the opening the widest part) a of the recess 44 of light-guiding pillar 42 is 80 ~ 95% of the diameter d of light-guiding pillar 42.If be less than 80%, then will reduce towards the transverse direction of light-guiding pillar 42 or the light that rolls oblique direction from light-guiding pillar 42 towards framework 11, and if be greater than 95%, then the area of the front end face 48 of light-guiding pillar 42 reduces, and the light penetrated from front end face 48 will reduce.At this, the diameter d of light-guiding pillar 42 shown in Fig. 5 is 6mm, and the opening diameter a of recess 44 is 4.9mm, and the luminous intensity distribution when ratio of the opening diameter a of the recess 44 of light-guiding pillar 42 and the diameter d of light-guiding pillar 42 is 82% distributes.As shown in Figure 5, light distribution angle is about 300 °, and obtains the wide luminous intensity distribution identical with transparent incandescent lamp bulb.In addition, now, the degree of depth b of recess 44 is 2.1mm, and the ratio of the degree of depth b of recess 44 and the opening diameter a of recess 44 is 43%.
Further, as shown in Figure 4, the degree of depth b of the recess 44 of light-guiding pillar 42 is 30 ~ 70% of the opening diameter a of recess 44.Degree of depth b due to recess 44 is opening diameter a30 ~ 70% of recess 44, therefore the light radiated from light radioactive department 47 to the transverse direction of light-guiding pillar 42 and can roll oblique direction reflection from light-guiding pillar 42 towards framework 11, thus can obtain the light distribution characteristic of the coordination as transparent incandescent lamp bulb.Namely, if the degree of depth b of recess 44 is less than 30% of the opening diameter a of recess 44, then the light reflected to the transverse direction of light-guiding pillar 42 can reduce, and, if the degree of depth b of recess 44 is greater than 70% of the opening diameter a of recess 44, then can reduce to the light rolling oblique direction reflection from light-guiding pillar 42 towards framework 11.If the light reflected towards the transverse direction of light-guiding pillar 42 reduces, or reduce to the light rolling oblique direction reflection from light-guiding pillar 42 towards framework 11, then luminous intensity distribution distribution becomes uneven, is difficult to reproduce the sense of glittering as transparent incandescent lamp bulb.
Further, as shown in Figure 6, the size of the end face (i.e. the plane of incidence 46) of another side of light-guiding pillar 42 is greater than the size of illuminating part 34.Therefore, it is possible to make the major part of the light radiated from illuminating part 34 incide light-guiding pillar 42, can light leak be reduced, increase the light radiated from light radioactive department 47 thus, improve sense of glittering.
Air layer 72 is formed between the plane of incidence 46 and illuminating part 34 of light-guiding pillar 42.If do not have air layer 72, that is, when the plane of incidence 46 and illuminating part 34 are close to, the part inciding the light of light-guiding pillar 42 from illuminating part 34 is not easy to penetrate from the cylinder of light-guiding pillar 42 to the end side of light-guiding pillar 42 leaded light.If have air layer 72, then the light radiated from illuminating part 34 produces refraction when incident to light-guiding pillar 42 by air layer 72, and the light after refraction is guide-lighting towards light radioactive department 47 in light-guiding pillar 42.
The gap of the air layer 72 between the plane of incidence 46 of light-guiding pillar 42 and illuminating part 34 brings greater impact to efficiency.As shown in Figure 7, if the gap of air layer 72 is comparatively large, then become large from illuminating part 34 towards the incidence loss of the plane of incidence 46, efficiency can decline.In addition, as the comparative example of loss, give the loss of the fixed part 43 at light conductor 13, the loss at reflectance coating 45, unknown losses, can see and show that the gap of air layer 72 brings greater impact to efficiency.Therefore, preferably make light-guiding pillar 42 and illuminating part 34 close as much as possible, reduce as much as possible to make the gap of air layer 72.But when making light-guiding pillar 42 close to illuminating part 34, light-guiding pillar 42 can contact with illuminating part 34, bring impact likely to illuminating part 34.In the present embodiment, illuminating part 34 (i.e. the surface of luminescent coating 33) caves in relative to frame portion 32, even if thus light-guiding pillar 42 is connected to frame portion 32, light-guiding pillar 42 also can not contact with luminescent coating 33.Therefore, it is possible to make light-guiding pillar 42 and illuminating part 34 close as much as possible, and can prevent from bringing impact to illuminating part 34.
Further, the fixed part 43 of light conductor 13 is given prominence to from 2 positions of the cylinder of another side of light-guiding pillar 42.The part inciding the light of light-guiding pillar 42 from the plane of incidence 46, towards fixed part 43 light leak being connected to light-guiding pillar 42, can make efficiency decline.Such as, with standing part from compared with the outstanding situation of the whole cylinder of another side of light-guiding pillar 42, give prominence to from 2 positions of the cylinder of another side of light-guiding pillar 42 by making the fixed part 43 of light conductor 13, light leak can be reduced, therefore, the light radiated from light radioactive department 47 can be increased, thus improve sense of glittering.
And, although fixed part 43 possesses the protuberance 50 of the connecting portion 49 being connected to light-guiding pillar 42 and the front end being arranged at connecting portion 49, but the thickness due to connecting portion 49 is set to the thickness being thinner than protuberance 50, and the width of connecting portion 49 is set to the diameter being less than light-guiding pillar 42, thus can guarantee the intensity of the fixed part 43 for light conductor 13 being fixed on framework 11, and also can reduce towards the light leak of fixed part 43.
Further, because cover 14 covers another side of illuminating part 34 and light-guiding pillar 42, thus can prevent light from radiating near framework 11, light only be radiated from light radioactive department 47, thus sense of glittering can be improved.
Then, sense of glittering is described.
The implication felt of glittering is " seeming bonnily luminescence ".
At this, the light source with sense of glittering is defined as that " mean flow rate is 5000cd/m
2(be preferably 45000cd/m above
2) and be the light source of below 0.000001sr from apparent size when observing apart from light source (light radioactive department 47) 10m " or " mean flow rate is 5000cd/m
2(be preferably 45000cd/m above
2) and size is 64mm
2(be preferably 17mm below
2) light source ".In addition, if be set to preferred numerical value, then the possibility obtaining the sense of glittering of more than transparent incandescent lamp bulb is higher.Its reason is as shown in following (1), (2).
(1) transparent incandescent lamp bulb is used in when the environment of atmosphere is paid attention in market etc. and has sense of glittering, but then very dazzling when being used in the environment of the attention work such as office.Therefore, the brightness conditions of light source is set as: the brightness that the brightness of can obtain glittering sense=feel is dazzling.
The result that the formula 1 that dazzling degree under direct-view quantizes calculates is by use: feel that dazzling mean flow rate is 5000cd/m
2(nUGR
dwhen=13, with reference to Fig. 8), really feel that dazzling mean flow rate is 45000cd/m
2(nUGR
dwhen=31, with reference to Fig. 8).Therefore, the condition of mean flow rate is set to 5000cd/m
2above, preferably 45000cd/m is set to
2.
In addition, these mean flow rates can be defined according to the measurement result of carrying out in the scope of the effective light distribution angle (present embodiment is 300 shown in Fig. 5 °) of lamp device 10.

As shown in Figure 9, be 5000cd/m in the mean flow rate of light source
2above region A1 can obtain sense of glittering, and is 45000cd/m in the mean flow rate of light source
2above region A2 can obtain the sense of glittering of more than transparent incandescent lamp bulb.
(2) radiance (light of radial diffusion) can be seen when looking at light source straight, and the light of radiance is thinner, then think to have more the light source glittering and feel.
For radiance, the light of the less radial diffusion of light source is thinner, is less than predetermined size as long as be thus set to by light source, just can realize having the light source glittering and feel.Therefore, at this, determine this predetermined size as follows.
Usually, by from observe apart from light source 10m so-called there is the light source of the transparent incandescent lamp bulb of the light source of sense of glittering time apparent size be set to the apparent size of the light source felt that can obtain glittering.This size is " below 0.000001sr ".Below, this size is called standard apparent size.
Further, the actual size of light source is set as, becomes standard apparent size from when light source 10m observes light source.The actual size of this light source is 64mm
2.In addition, if light source is circular or spherical, then 64mm
2the diameter of light source be 9mm, if light source is square or cube, then the length on 1 limit is 8mm.In addition, the size described at this is the size (with reference to Figure 12) on the face vertical with direction of visual lines.
Further, preferably the actual size of light source is set as becoming below 0.000001sr from apparent size when observing light source apart from light source 5m.Now, the actual size of light source is 17mm
2.In addition, if light source is circular or spherical, then size is 17mm
2the diameter of light source be 4.6mm, if light source is square or cube, then the length on 1 limit is 4.1mm.
In addition, when the apparent size of light source changes because of visual angle, can maximum according to size time angle define.In the present embodiment, as shown in Figure 5, when 0 °, outward appearance area is maximum, and illumination (light beam) is also maximum, but, also can be set to these areas and illumination becomes maximum when level (± 90 °).
As shown in Figure 10, be 64mm in the size of light source
2following region A3 can obtain sense of glittering, and is 17mm in the size of light source
2following region A4 can obtain the sense of glittering of more than transparent incandescent lamp bulb.
Further, the light radioactive department 47 of the lamp device 10 of present embodiment meets that " mean flow rate is 5000cd/m
2(preferred 45000cd/m above
2) and apparent size is the light source of below 0.000001sr " or " mean flow rate is 5000cd/m
2(preferred 45000cd/m above
2) and size is 64mm
2(preferred 17mm below
