Step 1:Form single lamp spot light according to showpiece size or with single lighting unit, or by micro USB public affairs mouth,
Several lighting units are connected into lamp bar by micro USB female seats, and the lamp bar after connection passes through upper circular rotary wheel and lower circular rotary wheel
Between rotate the position for adjusting adjacent illumination unit in the horizontal plane, the light curtain array of planar is formed by 2-8 lighting unit;
Step 2:The horizontal plane and vertical plane being in using subject in an imagination at center are positioned as benchmark,
Showpiece front, the back side and other dark side frame upper brackets, cost light fixture and by way of adding lampshade and sheen cloth come hidden
Main light source point is hidden, key light, fill-in light, backlight, the point light and top light etc. formed around showpiece.
2. for outdoor shooting light filling
Step 1:, as desired will be several by micro USB public affairs mouth, micro USB female seats in the relatively shade of outdoor shooting
Individual lighting unit connects into lamp bar, and the lamp bar after connection is by the rotation between upper circular rotary wheel and lower circular rotary wheel in horizontal plane
The position of interior regulation adjacent illumination unit, the light curtain array of planar is formed by 3-10 lighting unit;
Step 2:Light fixture freely is erected to nearby dark scene, generally faces polishing and 45 degree of inclination lighting directly, not by force
Property addition lampshade and soft light processed, form key light, ambient light, optically focused, the carry out light filling to scene.
The content not being described in detail in this specification, belong to prior art known to those skilled in the art.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
