Lampshade 7 is：There is translucency by acrylic resin etc. and be creamy white and have diffusible material, and formed
It is substantially circular.
Also, lampshade 7 and is releasably pacified in a manner of covering the front-surface side of ontology 1 including light source portion 2
Mounted in the outer peripheral edge portion of ontology 1.Specifically, by rotating lampshade 7, the cover installation part card (not shown) of what lampshade 7 will be set
It is installed by fastener 75 together in lampshade, the lampshade is disposed in the recess portion 14 of the outer peripheral edge portion of ontology 1 by fastener 75.
In the inner face of lampshade 7, it is formed with light transmission control unit 71.The light transmission control unit 71 is relatively small with the transmitance of light
Region 71a, formed with mode that the relatively large region 71b of transmitance of light is mixed.
Specifically, light transmission control unit 71 be lampshade 7 inner face side implement silk-screen (silk print) and formed, in light
The relatively small region 71a of transmitance, be formed with the relatively large region 71b of transmitance of multiple light.The transmitance phase of light
It is, for example, the part for being coated with white ink (ink) to smaller region 71a, the relatively large region 71b of transmitance of light is
It is not coated with the part for being furnished with white ink, which is to spread multiple (numerous) roundlets in the region for being coated with white ink
The mode of shape and formed.
That is, in the inner face side of lampshade 7, the ink of coating and printing white is carried out in the part for remaining multiple roundlet shapes.
Therefore, it is suppressed to the transmission of the relatively small region 71a of the transmitance of the light light irradiated, to the transmitance of light
Relatively large region 71b, it can carry out well to the transmission of the light of the partial illumination of multiple roundlet shapes.
Herein, the transmitance of light is relatively small, relatively large refers to：With the relativeness of region 71a, 71b, for example, light
The relatively small region 71a of transmitance be the situation that there is defined transmitance and formed mostly, to the photograph from light source portion 2
It penetrates light to be diffused, and irradiates shadow surface downwards, but penetrate, formed with being substantially not through sometimes or hardly
Situation.
That is, the region other than the relatively large region 71b of the transmitance of the light of lampshade is：With translucency, it is creamy white
And it is formed with having diffusivity.
It is the sheet material (sheet) in acrylic resin as its material etc. in addition, in the molding of such lampshade 7
Back side implements silk-screen printing, then, pressure in a manner of the part (part of uncoated ink) for forming multiple roundlet shapes
Forming (press forming) makes for roughly circular regulation shape.
In turn, the relatively small region 71a of the transmitance of the light and relatively large region 71b of transmitance of light can also phase
Anti- relationship and formed.That is, the relatively small region of transmitance as light, can also form the part of multiple roundlet shapes.This
When, as long as suitably setting the diameter dimension of roundlet shape according to design.
In turn, also can be by the aperture inside and outside lampshade 7, the relatively large region 71b of transmitance to form light.This
When, also can in a manner of so that the relatively small region of the transmitance of light, the region big with the transmitance of light is mixed shape
At.
In this way, being mixed with the relatively small region 71a of the transmitance of light, with the relatively large region 71b of the transmitance of light
Existing mode and the structure formed can use various structures, not be limited to specific structure distinctly.
In addition, the distance between pervasion component 3 and lampshade 7 are set to 20mm~60mm, be preferably set to 30mm~
50mm.The uniformity of irradiation light becomes good as a result, and being conducted from the installation surface side of substrate 21 to the heat of pervasion component 3 is：Via
Lampshade 7 and heat dissipation is effectively performed.
In turn, lampshade 7 is high in transparent base of the surface comprising minute surface, the permeability such as in transparent acrylic resin
Base material inner face, be formed with the light-transmissive film for including resin film-making material with multiple opening portion 71b.In addition, for transparent
Acrylic resin, it may be desirable to, the inside transmitance of the acrylic resin and outside including surface (interface) are saturating
Cross the high component of rate or including surface (interface) includes optical mirror plane and gloss, material that permeability is high.That is, transparent
As long as acrylic resin diffusivity is low, and can have an X-rayed the base material for the article being located in front of it via lampshade 7, then table is alternatively
Face be formed as bumps through prism processor.
The light-transmissive film 71a for being formed in 7 inner face of lampshade is, for example, shape bys silk-screen printing (silk screen print) etc.
At the film for having white.It is in multiple opening portion 71b that light-transmissive film 71a is formed：Be formed as the big of diameter 0.5mm~5mm or so
It is small.If opening portion 71b is less than 0.5mm, in the state that lampshade 7 is installed on apparatus body, the light of opening portion 71b is passed through
Line will die down, and will tail off in the ratio of light-emitting component 22 present on the straight line of connection viewpoint and opening portion 71b.Accordingly, it is difficult to
The light that light-emitting component 22 dazzlingly glitters is obtained via opening portion 71b.On the other hand, if opening portion 71b is 5mm or more,
There are the doubts that a plurality of light-emitting elements 22 are irradiated from 1 opening portion 71b, therefore feel compared to glittering, and people but will be allowed to feel to dazzle the eyes
Sense.Therefore, it may be desirable to, the opening portion 71b that silk-screen printing is preferably not carried out is less than light-emitting component 22, opening portion 71b's
Opening diameter most preferably 0.7mm~2mm or so.
Moreover, in the present embodiment, the forming region of opening portion 71b is：It is formed at least covering and along annulus
The circumferential direction of the substrate of shape and the range in the opposite region of light-emitting component 22 installed.That is, being surrounded by light-emitting component 22
The middle section of middle section, i.e. lampshade 7, does not form opening portion 71b.Moreover, covering and the opposite area of light-emitting component 22 extensively
Domain, along the opening portion 71b of all size that is formed of circumferential direction of lampshade 7 be random (random) and densely formed.
It is formed in the region of opening portion 71b, opening portion 71b is preferably 0.3%~0.6% relative to the ratio of light-transmissive film.If opening
Portion 71b is less than 0.3%, then there is no the ratios of light-emitting component 22 to get higher on the straight line of connection viewpoint and opening portion 71b, therefore
It can not feel that the opening portion 71b of light becomes more, glaringly the quantity of luminous opening tails off.On the other hand, if opening portion 71b is super
0.6% is crossed, then feels that the opening portion 71b of light can be very more, and the opening portion 71b of imperceptible light tails off.Therefore, compared to
The glittering sense that the flicker that independent multiple opening portion 71b are irregularly estimated caused by moving view point by is felt is dodged
Bright number tails off and feels and dazzle the eyes sense, feels that uncomfortable doubt improves.Therefore, it can be said that：The forming region of opening portion 71b
It is preferably 0.3%~0.6% relative to light-transmissive film.Moreover, the ratio of the opening portion 71b in 7 entirety of lampshade in present embodiment
Example is about 0.5%, and in the case where middle section does not form opening portion 71b, the opening portion 71b in 7 entirety of lampshade is preferably
0.4% or so.
In addition, the formation of lampshade 7 has the transmitance of the light-transmissive film of silk-screen printing, it may be desirable to 40%~80% with
Under.In present embodiment, the transmitance of wavelength 380nm~780nm is formed as 60% or so.If transmitance be 40% hereinafter,
Illumination is low immediately below then, and luminous flux will be too low, to be difficult to use as luminaire.On the contrary, if transmitance is 80%
More than, then underface illumination is high, and light beam is also abundant, and the light for carrying out self-emission device 22 irradiates efficiency well to shadow surface.But
It is luminance difference, the illumination of opening portion 71b (light-emitting surface brightness) and silk-screen printing region, that is, regions photic zone 71a (background luminance)
Difference becomes smaller, therefore, it is impossible to meet the surcharge effect dazzlingly glittered caused by the light leaked out from multiple openings.
In this way, to provide following luminaires, it is necessary to meet these conditions, the luminaire ensures as general lighting
Illumination needed for utensil, and have glittering sense, which is by the opening portion without silk-screen printing via Transparent lamp shade 7
71b and see, come caused by the irradiation light of self-emission device 22.
Such lampshade 7 and is releasably pacified in a manner of covering the front-surface side of ontology 1 including light source portion 2
Outer peripheral edge portion loaded on ontology 1.Specifically, by rotating lampshade 7, the cover installation part card (not shown) of lampshade 7 will be set to
It is installed by fastener 75 together in lampshade, the lampshade is disposed in the recess portion 14 of the outer peripheral edge portion of ontology 1 by fastener 75.
In addition, the structure formed in such a way that the opening portion 71b of lampshade 7 and photic zone 71a are mixed, can use each
Kind structure, is not defined in specific structure distinctly.For example, can also use the configuration for being arranged with systematicness of opening portion 71b.
In turn, in the position that the formation with lampshade 7 has the region of opening portion 71b opposite, the rib that surface is processed into minute surface can also be implemented
Mirror is processed.

The light of surface side mainly penetrates multiple roundlet shape, light transmitances relatively towards the light of the light transmission control unit 72 of lampshade 7
Big region 71b, to be irradiated through lampshade 7.At this point, the light irradiated from light-emitting component 22 is：It is inclined by pervasion component 3
It is irradiated outward via lampshade 7 to (deflection), dispersion, reflection, and towards respective direction of travel.
It, will be by being arranged on straight line with light-emitting component 22 when looking up such irradiation light below lighting device
, the relatively large region 71b of transmitance of light and look at light-emitting component 22 straight, to feel strong light.On the other hand,
Even if can if in the case where light source is not present on linking the straight line of the relatively large region 71b of transmitance and fulcrum of light
The light of light-emitting component 22 is set to spread by pervasion component, so as to feel faint light.By the way that pervasion component is set as
Lens can look at the light for carrying out self-emission device 22 straight from various angles, therefore the frequency or intensity of its glittering can be improved.
According to such structure, opening portion 71b as described below is constituted, i.e.,：If viewpoint, light-emitting component 22 are opposite with transmitance
Higher region 71b is located on straight line, then feel strong light, if carrying out self-emission device 22 after pervasion component is spread
Diffusion light, viewpoint and the relatively large region 71b of transmitance are located on straight line, then feel that weak light is felt in glittering, if linking
There is no light-emitting component 22 and carry out the diffusion light of self-emission device on the relatively large region 71b of transmitance and the straight line of viewpoint,
The then light of imperceptible glittering.
In this way, either in the case where looking up lighting device, or in the case of from the side from lighting device,
Be mixed see light-emitting component 22 for dotted light and with strong light come dazzlingly glitter part, see the member that shines
Therefore part 22 can be caused with faint light come the part of the part and imperceptible glittering dazzlingly glittered in light-emitting component 22
Dazzle be suppressed in the state of estimated.In addition, by moving view point, feel that the region of glittering makes the strong of light respectively
Degree changes or flickers repeatedly, to by the position for changing observation, can get each position and dazzlingly, irregularly show
Go out the decorative effect of intensity that glitters.In turn, by the light of the relatively small region 71a of transmitance by light, photograph can be realized
Penetrate the raising of the uniformity of light.In turn, in present embodiment, by using double-colored different light-emitting components 22, it can be seen that
Multiple opening portion 71b make the white light of daytime white and the light of light bulb color be mixed and dazzlingly flicker.As a result, in design side
Face can obtain more excellent effect.
On the other hand, since the back side of substrate 21 is contacted with 1 face of ontology, the heat generated from light-emitting component 22
It will effectively conduct to ontology 1, and be radiated with large area.Moreover, near the peripheral side of substrate 21, along substrate 21
Periphery and be formed with order difference part 13, therefore can be by the order difference part 13 come increasing heat radiation area, so as to improve ontology 1
The heat dissipation effect of peripheral part.In addition to this, which can play the stiffening effect of ontology 1.
Moreover, ignition device 4 is disposed between mounting portion 6 and substrate 21, therefore, mitigate ignition device 4 by from
The influence of the heat of substrate 21.This is because the heat of substrate 21 is：In the presence of the peripheral direction towards ontology 1 conducts and radiates
It is inclined to and causes.
In addition to this, the flat part 33 of pervasion component 3 is contacted with the installation surface side forming face of substrate 21, therefore, also can
It is enough to radiate from the installation surface side of substrate 21 from front-surface side via pervasion component 3.Moreover, at this point, pervasion component 3 covers
The entire surface of substrate 21, therefore charging part is protected.
As described above, according to the present embodiment, when looking up lighting device, it can be seen that light is designed and the light of point light source
It dazzlingly glitters, decorative effect is can get, to improve performing effect.In turn, it is possible to provide a kind of luminaire is connected by being arranged
The pervasion component 3 of continuous ground covering luminous element 22, so as to realize irradiation light the uniformity raising.
In addition, the present invention is not limited to the structures of the respective embodiments described above, without departing from the spirit of the invention
It can carry out various modifications.For example, the shape of light transmission control unit 71, the light relatively large region 71b of transmitance is not limited to
Circle, in turn, it is also applicable that the hole to being formed in the light transmission control unit on entire lampshade carries out patterned way.
