In the LED element that light-emitting component 22 is RGB type, so can come by adjusting the brightness of blue light, green light and red light
Project the light of various colors.Light-emitting component 22 can project the simulation such as imitating blue sky, cloudy day, sunset clouds as a result,
Outdoor optical.
As shown in figure 3, light-reflecting components 30 are configured in a manner of surrounding a plurality of light-emitting elements 22, to from light-emitting component
22 light projected have reflexive optical component.That is, light-reflecting components 30 will be projected from light-emitting component 22 and to be incident on light anti-
Penetrate the light reflection of component 30.Specifically, light-reflecting components 30 will be incident on the interior table of light-reflecting components 30 from light-emitting component 22
The light in face (in other words, the face of 22 side of light-emitting component of light-reflecting components 30) is to 40 lateral reflection of light diffusing member.
In the present embodiment, light-reflecting components 30 are made of the wall portion 31 for surrounding a plurality of light-emitting elements 22.That is, light
Reflection component 30 is the component for the frame-shaped for surrounding a plurality of light-emitting elements 22.In addition, the shape of light-reflecting components 30 does not limit
In frame-shaped.As long as light-reflecting components 30 have the wall portion 31 for surrounding a plurality of light-emitting elements 22, shape is not specially limited.
User from light-emitting component 22 it can be seen that by projecting and not being incident on via wall portion 31 the light of light diffusing member 40
The display picture (hereinafter, being also denoted as real image) of formation and by being projected from light-emitting component 22 and being reflected by wall portion 31 and be incident on light
The display picture that the display picture (hereinafter, being also denoted as reflection image) that the light of proliferation part 40 is formed is formed.In other words, by real image and reflection
As forming 1 display picture.In the case where not forming light-reflecting components 30, display by real image as only being formed, the display of formation
Size degree as being substrate 21.On the other hand, in the case where forming display picture by real image and reflection image, it can reproduce and compare base
The big display picture of the size of plate 21.For example, the such display of infinite expanding can be reproduced as (for example, blue infinite expanding
It).In turn, by the way that light-reflecting components 30 are arranged, the display picture of bigger range can be reproduced, so substrate 21 can be made to become
It is small.That is, lighting device 1 can be made to minimize.Furthermore it is possible to reduce the quantity for being installed on the light-emitting component 22 of light emitting module 20.
Light-reflecting components 30 pass through the reflecting plate implementation expansion to having the mirror surface formed such as the metal material as aluminium (Al)
It dissipates processing and is formed.The delustring processing of DIFFUSION TREATMENT e.g. anodized (Alumite) processing etc..As long as in addition, will diffusion
Processing is at least implemented the inner surface of light-reflecting components 30 (wall portion 31).In the case where wall portion 31 is mirror surface, by quilt
The reflection image that the light that wall portion 31 reflects is formed becomes mirror image.It is mirror image that user, which easily identifies out the reflection image, simulates the effect of sky
Fruit decline.On the other hand, as noted above, by carrying out delustring processing, reflection image becomes picture fuzzy slightly.User as a result,
Being not easy perception reflex seems mirror image, for display as being not easy to feel awkward sense.
In addition, not including white processing in the DIFFUSION TREATMENT implemented to light-reflecting components 30.If light-reflecting components 30 are
White color system reflecting plate is then issued by the wide cause of white color system baffle reflection in heterogeneity, so for example losing the sky of reflection image
With the exploring sense of cloud, the effect decline of sky is simulated.In addition, the inner surface (face of 22 side of light-emitting component) of light-reflecting components 30
It can be mirror surface.In the case where the inner surface of light-reflecting components 30 is mirror surface, as among the above also explanation like that, real image and instead
The brightness of image has continuity, can reproduce the few display of awkward sense compared with light-reflecting components 30 are the situations of white
Picture.Further, since the light for being incident on light-reflecting components 30 from light emitting module 20 can be totally reflected to 40 side of light diffusing member, institute
The loss of the light from light emitting module 20 can be reduced.
Here, the height of light-reflecting components 30 (wall portion 31) (length of Z-direction) is illustrated.For example, if light
The height of reflection component 30 is low, then light-emitting component 22 looks like granular, and user is easy to display as feeling awkward sense.Another party
Face is able to suppress light-emitting component 22 and looks like granular situation, but lighting device if the height of light-reflecting components 30 is high
1 enlargement.In addition, whether light-emitting component 22 looks like spacing and light diffusing unit granular, also by installation light-emitting component 22
The influence of mist degree (Haze) value of part 40.In other words, by the height of light-reflecting components 30, the spacing and light of installation light-emitting component 22
The haze value of proliferation part 40 is set as, so that light-emitting component 22 appears not to be granular.
In addition, if the height of light-reflecting components 30 low (in other words, light emitting module 20 is at a distance from light diffusing member 40
It is small), then picture of the display being reproduced as becoming flatness.Therefore, from the viewpoint of the display picture that reproduction has depth sense, preferably
Be that the height of light-reflecting components 30 is set to height.
Light diffusing member 40 be will from the light of 20 side of light emitting module incidence spread and to the ground side project optical component.Tool
For body, light diffusing member 40 be will from the light of the light incident surface 41 of light diffusing member 40 (face of Z axis positive side) incidence spread,
The diffusion panel projected from light emergence face 42.
Light diffusing member 40 has translucency and makes the light diffusing of light diffusion for the light projected from light emitting module 20.
For example, by the resin material or glass by transparent acrylic acid or PET (Poly Ethylene Terephthalate) etc.
The transparent panel that glass is constituted implements diffusion processing to make light diffusing member 40.Since light diffusing member 40 is by transparent material structure
At the light diffusing member 40 has high transmissivity.For example, the full light transmittance of light diffusing member 40 is 80% or more, more
Preferably 90% or more.Thereby, it is possible to reduce the loss of the light as caused by light diffusing member 40, bright display picture is reproduced.
Also, light diffusing member 40 is made and implementing diffusion processing to transparent panel.By diffusion processing to light diffusing unit
The light incident surface 41 of part 40 and at least one face of light emergence face 42 are implemented.For example, being processed as diffusion, to be formed by fine
Prism processing for the prism that dotted hole (recess portion) is constituted etc..Fine hole is the hole of the size for the degree that user cannot recognize,
Such as fine hole is cone or pyramid etc..For example, fine hole in the case where being cone by top and bottom surface

Show picture).It is being difficult to obtain in the arranging of natural daylighting or undergrond street etc. in addition, lighting device 1 for example also can be set.
[2. effects etc.]
Then, the effect of the lighting device 1 in relation to present embodiment is illustrated.
Lighting device 1 in relation to present embodiment is the illumination dress for being embedded to the baried type of ceiling 70 (an examples of building materials)
Set 1, have: light emitting module 20 has substrate 21 and is configured at a plurality of light-emitting elements 22 of substrate 21；Light diffusing member 40, tool
There is translucency, light emitting module 20 is covered；And specular layer 23 (an example of mirror-reflection component), it configures in light emitting module
Between 20 and light diffusing member 40.Light emitting module 20 projects light towards light diffusing member 40, and specular layer 23 will expand from light
The light of separate component 40 reflects.
As a result, from light-emitting component 22 project and by the face of 20 side of the light emitting module of light diffusing member 40 reflect light (such as
Reflected light R1) layer 23 (an examples of light-reflecting components) is specularly reflected to 40 lateral reflection of light diffusing member.That is, user it can be seen that
By the 1st display picture that the light of light diffusing member 40 is formed is projected and transmitted from light emitting module 20 and by being penetrated from light emitting module 20
The 2nd display picture that the light of light diffusing member 40 is formed has been transmitted after being reflected out and by light diffusing member 40 and specular layer 23.
In other words, user is it can be seen that the 1 display picture formed by the 1st display picture and the 2nd display picture.Form the light quilt of the 2nd display picture
Light diffusing member 40 and specular layer 23 reflect, correspondingly, compared with the light for forming the 1st display picture, in light emitting module 20 and
The distance transmitted between light diffusing member 40 is longer.Therefore, seem the 2nd display as being formed in than the 1st display as leaning on from user
It is inboard.That is, can not make lighting device enlargement by forming the 2nd display picture and reproduce the display picture for more having depth sense.Cause

40 lateral reflections.That is, only passing through the surface configuration specular layer 23 in 40 side of light diffusing member of substrate 21, it will be able to not make to shine
Bright device is enlarged and reproduces the display picture for having depth sense.
In addition, the face of 20 side of light emitting module of light diffusing member 40 is smooth face.
Thereby, it is possible to increase from light emitting module 20 project, by light diffusing member 40 20 side of light emitting module face reflect
The ratio of light.That is, the light for having transmitted light diffusing member 40 in reflected light R2 can be made to be formed by the 2nd display as becoming more
Bright picture.Therefore, compared with the case where face of 20 side of light emitting module of light diffusing member 40 is not smooth face, can be made
1 display becomes smaller as the difference of the brightness with the 2nd display picture, so the display picture that awkward sense further decreases can be reproduced.
In addition, there is anti-reflection layer 44 in light diffusing member 40 and the face of light emitting module 20 opposite side.
As a result, the outer light reflected by rising portions 12b be incident on light diffusing member 40 with 20 opposite side of light emitting module
In the case where face (face of ground side), the light of the incidence is able to suppress by the lateral reflection to the ground of light diffusing member 40.That is, can press down
Rising portions 12b processed mirrors light diffusing member 40.It is being illuminated from outer smooth bring rising portions 12b to mirroring for light diffusing member 40
Occur when device 1 is lighted and when extinguishing in both sides.Therefore, anti-reflection layer is configured by the face of the ground side in light diffusing member 40
44, it can reduce the awkward sense of display picture when lighting device 1 is lighted, and can be improved illumination when lighting device 1 extinguishes
The beauty of device 1.In addition, lighting device 1 may not possess rising portions 12b, rising portions 12b can also be formed by building materials.
