Be easy to understand.The utility model can be emerged from by many various forms of embodiments, the protection of the utility model
Range is not limited only to the embodiment mentioned in text.
In the accompanying drawings, the size and number etc. of each component shown in the drawings are to be arbitrarily shown, and are not constituted practical to this
Novel restriction.Apparent in order to make to illustrate, some places suitably exaggerate the thickness of component in attached drawing.
The film studio annular facade that the lighting device of the present embodiment is adapted to uses 12 side shape schemes, the facade of lighting device
Lighting part, including 12 face barn doors, light bar plate and equal tabula rasa 4, wherein barn door and equal tabula rasa 4 are rectangle.Such as Fig. 2 institute
Show, light bar plate is made of the bracket 2 of multiple light bar 1 horizontally disposed from top to bottom and the installation light bar, and bracket 2 is generally selected
" door " font bracket can also select other such as T-shaped etc., or even for 1 convenience of fixed light band, whole face can be selected saturating
Isotropic disk works as bracket, and light bar 1 is directly anchored on transparent panel." door " font bracket is selected in the present embodiment, it is assumed that integral illumination dress
Setting polygon diameter is 4.6 meters or so, and every elevation is 2.7 meters, and width is 1.2 meters, and in the environment of this parameter, every face is needed
Will 2 groups of horizontal lowering from the bracket 2 of light bar plate from top to bottom respectively have the lamps of 18 3030 diffusing reflection light bar as shown in Figure 1
Band 1 reaches the illuminating effect of sufficient intensity with this, and it is on one side 518.4w, every group of light bar claims respectively that every light bar, which is 14.4w,
For the first light bar and the second light bar, it is connected between light bar and light bar by connecting cable 3.Light bar plate is connected two-by-two, around film studio
As soon as parallel arrangement, constitutes the light bar layer of lighting device inside inside week.In each light bar plate face side phase into film studio
The equal tabula rasa 4 of acrylic frosted of the position of same distance vertically-arranged one side 1mm thickness parallel with light bar plate, all 4 liang of two-phases of equal tabula rasa
Company forms equal photosphere；In the position of each light bar plate face to film studio outside same distance, vertically-arranged one side parallel with light bar plate is black
The barn door of color, all barn doors are connected to form light shield layer two-by-two.As shown in figure 3, the light shield layer being sequentially arranged from outside to inside, lamp
Belt and equal photosphere and the film studio facade are concentric, parallel, and the light shield layer in outside is not drawn in Fig. 3.Light bar plate and light
Plate 4, barn door distance cannot be too close, too recent photo rings heat dissipation, can not be too far, entire lighting device thickness is too if too far
Thickness, influence arrangement and it is practical, generally according to the size Control in specific film studio in 4~8mm, the present embodiment preferred 6mm.In order to
The disengaging for facilitating shooting object or person, has one side light bar plate and inside and outside corresponding equal tabula rasa, barn door that can individually dismantle.
The present embodiment is the lighting device to match with the film studio of 12 face polygonized structures, if film studio cross section is
Other polygonized structures, the equal tabula rasa of matched lighting device, light bar plate, the quantity of barn door and connection angle carry out it is corresponding
Adaptation.
The overhead illumination part of lighting device is to install size identical as film studio plane in high 2.7 meters of the position in top
The 12 equal tabula rasas of side shape acrylic polished top, then similar shape is installed with the top barn door of size, top above the equal tabula rasa in top
Portion's light bar 11 is directly anchored on barn door.Top barn door at a distance from the equal tabula rasa in top general control in 4~8mm, this reality
Apply preferred 6mm in example.Top light bar 11 can be using top barn door center as the center of circle, and top is uniformly fixed in concentric circles
It, can also be using barn door center as the center of circle, in the arrangement of homogeneous radiation shape on barn door.In order to guarantee that brightness is consistent, list is avoided
Light bar is too long at the top of root, in the lighting device in the biggish film studio in space, the general arrangement for selecting homogeneous radiation shape, and top
The quantity of portion's light bar is determined according to overhead illumination brightness requirement and film studio height.As shown in figure 4, the present embodiment is exactly by 90
Top light bar 11 is in a manner of 4 ° of interval homogeneous radiation shape arrangement two-by-two, and lamp bead is mounted on downward on the barn door of top, circular groups
At a circle, overhead illumination light bar 11 is completed with this and is installed.The light bar 11 of overhead illumination can equally be divided into two groups, every group of lamp
Band is referred to as the first light bar and the second light bar, connects control circuit by top connecting cable 31.
All light bar are connected with control circuit, can control the brightness of light bar by control circuit.Lighting device is each stood
The first light bar and the second light bar of face light bar plate and overhead illumination can be connected with multiple control circuits respectively, can also all
One light bar connects a control circuit, and all second light bar connect a control circuit, it might even be possible to all first light bar and the
Two light bar are connected in the same control circuit.In this lighting device, to obtain uniform, brightness, the illumination of adjustable color effect
Fruit, general first light bar and the second light bar at the top of the bracket 2 carry out interlaced arrangement down, arrangement spacing is uniform.Each
One light bar individually connects to the control circuit, and each second light bar also individually connects to the control circuit, and can be distinguished by control circuit
The brightness of independent control the first light bar and the second light bar.In this way, the first light bar and the second light bar are selected different-colour respectively
Diffusing reflection light bar, adjust separately the brightness of the first light bar and the second light bar, the tune to entire lighting device colour temperature may be implemented
It is whole, to match demand of the different subjects in three-dimensional modeling information collection to light luminance, colour temperature.For example, the first light bar
White light (colour temperature is 7000K or so) diffusing reflection light bar is selected, second light bar selects the unrestrained of warm light (colour temperature is 3000K or so)
Reflectoscope band, then by adjusting 40% that the first light bar brightness is all light, the brightness of the second light bar is the 10% of all light, in light bar
In the case where comparatively dense is arranged, the first light bar and the mixing of the second light bar show whole colour temperature in 5000K or so, i.e., for taking the photograph
The colour temperature of the entire lighting device of studio's illumination is in 5000K or so.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that this field ordinary skill without
It needs creative work according to the present utility model can conceive and makes many modifications and variations.Therefore, it is all in the art
Technical staff passes through logical analysis, reasoning, or a limited experiment according to the design of the utility model on the basis of existing technology can
It, all should be within the scope of protection determined by the claims with obtained technical solution.
