Preferably, the arc angle of the ogee track of described key light lamp track and/or auxiliary light modulation track is 90 degree.
Preferably, each track xsect described is I-shaped.
Advantage of the present invention is as follows:
1. can install six light fixtures, have unexistent shadow lamp and the ceiling light of disappearing of conventional well font smallpox rail, photographic effects is better, and ceiling light rail is circular arc, ceiling light runs thereon, can the running orbit of simulated solar in one day, the better effect of construction simulation of natural light.
2. each lamp track is independent, interacts, cause the problem being difficult to control light ratio when there is not conventional well font smallpox rail adjustment lamp position.
3. key light lamp track, auxiliary light modulation track set up track body by inverse-arc shape track and straight shape track groups, and lamp installation is on straight shape track, when straight shape track is along inverse-arc shape orbital motion, light fixture can run on the arbitrfary point of arcuate sectors, carries out independent lighting accurately.
4. three-dimensional track and compound orbit angle are arranged rationally, do not waste track.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
As shown in Figure 1, the present invention comprises six tracks: disappear shadow lamp track 1, ceiling light track 2, key light lamp track 3, auxiliary light modulation track 4, profile light modulation track 5, No. two profile light modulation tracks 6.
The described shadow lamp track 1 that disappears is positioned at ground, in circular arc.Key light lamp track 3, auxiliary light modulation track 4, profile light modulation track 5, No. two profile light modulation tracks 6,2, ceiling light track are suspended from ceiling.Disappear shadow lamp track 1 in key light lamp track 3, auxiliary light modulation track 4 vertical projection dead ahead, and namely before photographer, the center of circle inwardly.
Below each track is described in detail.
Described ceiling light track 2 is circular, is positioned at the center of ceiling track.Preferably, be provided with breach, facilitate lamp installation.
A profile light modulation track 5, No. two profile light modulation tracks 6 are symmetrical at ceiling light track 2 rear the right and left, construct identical, be the compound track that arc track and straight shape track form: namely arc track both sides respectively arrange a straight shape track, the center of circle of described arc track inwardly, arc angle is 28 degree, and the radian of whole profile light modulation track is 93 degree.The benefit that a profile light modulation track 5, No. two profile light modulation tracks 6 are designed to above-mentioned compound track is had:
1, clearance light mainly modifies clothes, hair light, performance surround lighting, its strong and weak light ratio effect directly affecting key light and fill-in light, and flashlamp is the same with other light sources character, also by the restriction of inverse square law, if track is not arc angle, be difficult to calculate light intensity.2, have at straight shape interorbital the arc track seamlessly transitted, be conducive to railcar even running, find through test, what radian was that the arc track of 28 degree can be optimum meets this requirement.3, the whole radian of compound track is 93 degree, and angle is large, can realize multiple cloth light effect, as wide light, narrow light, lines light etc., and not waste track.
Further, the straight shape track of a profile light modulation track 5, No. two profile light modulation tracks 6 vicinities can link together, and become a track, but clearance light, No. two clearance lights does not change its direction of motion and range of movement.
Key light lamp track 3, auxiliary light modulation track 4 are symmetrical at ceiling light track 2 front the right and left, construct identical, the three-dimensional track be all made up of an ogee track and a straight shape track.Outwardly, radian is 90 degree in the center of circle of described ogee track.Described straight shape track is arranged from the ogee track center of circle along arc edge direction, and described straight shape track can move along arc limit centered by the ogee track center of circle.Lamp installation is on straight shape track, and when straight shape track runs along arc limit, light fixture can run on the arbitrfary point of arcuate sectors, carries out independent lighting accurately.
The shadow lamp track 1 that disappears is positioned at ground, in circular arc, arc angle is preferably 115 degree, because in the present invention, subject is positioned at vertical projection position, the ceiling light center of circle, experimentally finds, arc angle is preferably 115 degree, ensure that the shadow lamp that disappears aims at subject all the time in operational process, shadow lamp of guaranteeing to disappear can keep the accurate luminance of needs anywhere.During use, the shadow lamp that disappears can to facing upward 30 degree, crosses dark shading with what ensure to eliminate clothes and face.
Preferably, each track xsect described is " work " font, runs to facilitate its car that gets on the right track.And the two ends of each track arrange catch, prevent from running and overstep the limit.
Advantage of the present invention is as follows:
1. can install six light fixtures, have unexistent shadow lamp and the ceiling light of disappearing of conventional well font smallpox rail, photographic effects is better, and ceiling light rail is circular arc, ceiling light runs thereon, can the running orbit of simulated solar in one day, the better effect of construction simulation of natural light.
2. each lamp track is independent, interacts, cause the problem being difficult to control light ratio when there is not conventional well font smallpox rail adjustment lamp position.
3. key light lamp track, auxiliary light modulation track set up track body by inverse-arc shape track and straight shape track groups, and lamp installation is on straight shape track, when straight shape track is along inverse-arc shape orbital motion, light fixture can run on the arbitrfary point of arcuate sectors, carries out independent lighting accurately.
4. three-dimensional track and compound orbit angle are arranged rationally, do not waste track.
These are only preferred case study on implementation of the present invention; for a person skilled in the art, the present invention can have various modifications and variations, within the spirit and principles in the present invention all; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
