Technical field
The utility model relates to video stage light tool technical field, relates in particular to a kind of softbox for the LED soft light and the soft light of this softbox is housed.
Background technology
Soft light refers to that light is soft does not have an obvious shade, is suitable for reflecting form and the color of object, gives the photography luminaire of the sense of the soft exquisiteness of people.The light that flash lamp can be up to becomes soft, makes photo seem more natural.Its principle is exactly by resistant to elevated temperatures translucent plastic stiff flash lamp direct projection light, be converted into soft diffused light, the high hot spot of disliking on cancellation portrait and other shot object, make your photo beautiful nature as taking in the photo studio, therefore soft light often is used in the movies-making, because the light of its emission is evenly soft, after be applied to video display stage lighting.
Stage cloth is the important component part that consists of of stage performance space only, is according to the development of plot personage and required special scenes to be carried out the Lighting Design of visual environment, and design idea is represented artistic creation to spectators again in the mode of VIS.Therefore, need multiple light fixture to be used in the stage lighting, in stage performance, soft light can better reflect form and the color of object, give the people sense of soft exquisiteness, still existing soft light major part is reflect flexible-light lamp, light source can direct irradiation on the photographed object surface, light becomes scattered beam behind the reflector secondary reflection, thereby forms the large tracts of land light source.Therefore, traditional soft light projection scope is large, and the field of illumination does not have obvious contour edge.
Provide a kind of built-in three-primary colours soft-light lamp capable of regulating angle such as Chinese patent application 200420120023.8, it is characterized in that, consisted of by analog bracket 1, lamp panel cover 2, lamp panel bonnet 3.On four angles of analog bracket 1 small sircle hole is arranged respectively, respectively there is a U-shaped draw-in groove 5 both sides of analog bracket 1 interior correspondence, wherein have on the limit of a U-shaped draw-in groove 51 elastic steel sheet 6 is arranged.Undaform groove reflector 7 is inserted in lamp panel cover 2 interior fixing, and lamp tube socket 8 is installed on the medial surface of lamp panel cover 2, and fluorescent tube carriage 9 is installed in and forms lamp panel cover 2 on the corresponding side.Although what the light that the soft light in this application can make light source launch can be softer is radiated on the object, and does not have obvious shade, the light that structure is launched in this does not have obvious stereovision, and stage effect is had adverse effect.
