Embodiment
In order to illustrate more clearly of the present invention, the present invention is done further with reference to preferred embodiments and drawings
It is bright.Similar part is indicated with identical reference in accompanying drawing.It will be appreciated by those skilled in the art that institute is specific below
The content of description is illustrative and be not restrictive, and should not be limited the scope of the invention with this.
Fig. 1 shows the schematic diagram according to a kind of variable embodiment of visible ray darkroom 1 of background illuminance of the invention, described visible
Brightness room 1 includes the darkroom outer wall of isolation visible ray, the visible light source 13 that is placed in the darkroom outer wall and for showing darkroom
The visible light illumination meter 14 of background illuminance.The darkroom outer wall includes hemisphere face shape dome 11 and supports the support of the dome 11
Wall 12, the hemisphere face shape dome 11 can provide diffusing reflection surface for darkroom illumination.Characterized according to the visible light illumination meter 14
Darkroom background illuminance adjust the input voltage of visible light source 13, it is seen that the visible ray sent of light source 13 is with input voltage
Change and change, can constantly adjust the input voltage of visible light source 13, the darkroom background for characterizing the visible light illumination meter 14
Illumination reaches the background illuminance of needs.
The dome 11 is hemisphere face shape, it may include keel 111 and the curtain plate 112 of hemisphere face shape.The keel 111 can be by
50 longitudinal components and 7 latitudinal components bend to a semi-spherical shape, hemispherical a diameter of 18m.
The component of keel 111 is that 64x32x3 millimeters of materials of size are aluminum rectangular tube.The dome 11 is support with keel 111, in institute
State and curtain plate 112 corresponding with the semi-spherical shape of the formation of keel 111 is set on keel 111.The curtain plate 112 is by 288 pieces, 1mm
Thick aluminum panel is spliced, and using aluminum alloy plate materials integrated design, is stretched and is molded by compound curved surface mould.In the curtain
Gap between 112 adjacent two pieces of panels of plate throws flat after being filled with putty, forms the inner surface of the dome 11.The dome 11
Inner surface spraying visible light wave range reflectivity is more than 90% diffusing reflection white coating, forms matte surface.The knee wall 12
For cylindrical shape, diameter 18m is correspondingly arranged with the dome 11.A windowless door, door closure are opened up on the knee wall 12
