Abstract
The utility model discloses a portable type transmission and focusing lighting device having the advantages of evenly scattered lighting rays, adjustable lighting range, adjustable brightness, very low veiling glare, and high light effect. The utility model comprises an optical system, a shell body, and a slide seat. The utility model is characterized in that a diffusion-effect filter 1, a convex lens 3, a lamp bulb 4, and a spherical reflection mirror 5 are arranged in a lamp room in sequence; the lamp bulb 4 and the spherical reflection mirror 5 are fixed on the slide seat 13 which is sheathed on a slide track 16.
Description
The utility model belongs to portable news interview light fixture class, specifically a kind ofly can improve the adjustable portable transmission focusing lamp that is used for the illumination of news interview and video display of illuminating ray uniformity, brightness and illumination zone.
Widely used portable illuminating lamp in news interview mainly adopts reflecting light to learn a skill at present.Shortcomings such as because to exist brightness of illumination inhomogeneous for it, shadow surface center brightness and edge brightness differ from more than 7 times, and illumination zone is non-adjustable, and the non-adjustable and veiling glare of brightness is bigger more and more are difficult to satisfy the requirement of film ﹠ TV circles to the shooting picture quality.
The purpose of this utility model then is the problem that exists at above-mentioned prior art, and a kind of illuminating ray uniformly dispersing is provided, and illumination zone is adjustable, the high light efficiency that adjustable brightness and veiling glare are extremely low, portable transmission focusing lighting.
Technical solution of the present utility model:
A kind of portable transmission focusing lighting, comprise optical system, housing, slide, it is characterized in that being equipped with successively in the lamp house scrim 1, convex lens 3, bulb 4 and spherical reflector 5, wherein bulb 4 and spherical reflector 5 are fixed on the slide 13, and slide 13 is enclosed within on the slide rail 16.
The utility model has following advantage compared to existing technology:
1, transmission-type optical focus technology, the light uniformly dispersing that light fixture is projected, the brightness at shadow surface center and edge brightness difference be less than 10%, thereby improved the stereovision and the color perspectivity of taking indoor picture.
2, the sheen of uniqueness focusing technology, the illumination zone of projection light and brightness can change continuously.
3, specially designed lamp house, case thermal insulation radiator structure, it is little, in light weight to have a volume, uses advantage easy to adjust.Can prevent that lamp outer casing from crossing the blanching people, also can prolong bulb service life.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model partly is made up of optical focusing system, housing, lamp house, slide 13 and lamp socket 11 etc.Optical system is made up of scrim 1, filter 2, convex lens 3, bulb 4 and spherical reflector 5.The light that bulb 4 sends forward and send backward and shone on the target by scrim 1 again behind light planoconvex lens 3 optically focused of spherical reflector 5 backspaces.Bulb 4 and spherical reflector 5 are fixed on the slide 13.When slide 13 during along slide rail 16 move left and right, the distance of light source and convex lens 3 changes, and the angle of departure of transmitted light is changed, thereby has realized the adjustment of illumination zone and illumination.If need to adjust the colour temperature of light source, can insert filter 2 at convex lens 3 and 1 of scrim.Scrim 1 can be done softening to incident light and handle.The lamp casing part is made up of inner casing 6, shell 7 and bottom 15, and shell 7 is connected through heat-barrier material piece 8 with inner casing 6, and shell 7 is connected by rotating shaft 10 with bottom 15, the front portion of inner casing 6 and bottom-open, and the top has shutter.Convex lens 3 are connected with bottom 15 through heat-barrier material piece 14.Slide rail 16 left ends are through heat-barrier material piece 14, and right-hand member is fixed on the bottom 15 through heat-barrier material piece 9.When with counterclockwise, be the axle center with rotating shaft 10, raise shell 7 to the upper right side, just expose lamp house, be convenient to more change the bulb 4.Slide 13 is connected on the lamp socket 11, but the up-down adjustment angle of pitch, to change the light-illuminating angle.Lamp socket 11 is fixed on video camera or the handle through handwheel 12.
Claims (6)
