The device is simple in structure, easy to manufacture, convenient and reliable in use and operation, excellent in mixed light effect, rich and adjustable in color, and can be widely used in various lightings such as artistic modeling, decoration, stage design, photography and the like.

Description

Adjustable color lighting device

technical field

The invention relates to an illuminating device which is especially suitable for artistic modeling and can emit colored mixed light of various tones.

Background technique

At present, more and more people need to use artificial lighting color light to change or enhance the atmosphere of the surrounding environment, such as artistic modeling, decoration, stage design, film and television photography, etc., often require a variety of color lighting with rich and varied colors to achieve its artistic expression Effect. Generally, a simple combination of multiple different monochromatic light sources is used. Since the required light color cannot be perfectly mixed from one light source, it is often difficult to achieve the desired design concept effect, and the color-changing operation is also difficult. Very clumsy, for this reason, once someone was 93120774 " color mixing method in adjustable color lighting and adjustable color lighting device with this method " technology to solve the color mixing light source problem according to Chinese invention patent application number, but this device structure, The operation is complicated, and the complete mixing of multiple colors of light cannot be achieved, and the effect is coaxially emitted from one light exit hole.

Contents of the invention

The object of the present invention is to provide an adjustable color lighting device, which not only has a simple and reasonable structure, is extremely easy to operate, but also truly realizes the injection of mixed light of various tones from one lens, which can perfectly realize the artistic design effect .

The present invention is realized in the following manner:

The adjustable color lighting device is composed of three light sources that can emit different colors. A zoom lens is arranged in front of the first light source, and the central axes of the two coincide on a straight line. It is arranged on both sides of the central axis between the first light source and the zoom lens, and the central axes of the second light source and the third pumping light beam are respectively perpendicular to the central axis of the first light source, and a piece of Rotatable half mirror. With such a combination device in a dark box, the light emitted by the three light sources is transmitted or reflected and converged on the zoom lens, and then emitted together through the zoom lens.

Using this device, by rotating the two half mirrors and adjusting the luminous intensity of the three light sources respectively, various mixed lights of different tones can be obtained. The positional differences of the various shades of light do not appear on the illuminated screen. It can be widely used in various occasions such as artistic modeling, decoration, stage design and other colored lighting.

Fig. 1 is a schematic diagram of the combined structure of the adjustable color lighting device of the present invention.

Fig. 2 is a schematic view of the use state of the adjustable color lighting device of the present invention placed on an auxiliary rack.

Detailed ways

The structure of the present invention will be further specifically described below with regard to the embodiments given in the accompanying drawings.

The adjustable color lighting device is combined in the following way in a dark box: with reference to Fig. 1, three light sources that can emit different colors are included in its composition, a zoom lens 4 is arranged in front of the first light source 1, the two The central axis coincides on a straight line, and the second light source 2 and the third pumping beam 3 are respectively arranged on both sides of the central axis between the first light source 1 and the zoom lens 4, and the second light source 2 and the third pumping beam The central axis of 3 is perpendicular to the central axis of the first light source 1, and the first half mirror 5, the second fast half mirror 6, and the three light sources are respectively provided with a rotatable angle at two intersections. The emitted light is transmitted or reflected by the half-mirror and converges on the zoom lens, and is emitted together through the zoom lens.

The first light source 1 or the second light source 2 and the third pumping light beam 3 are composed of a reflector 9 , a tungsten halogen lamp 10 , a condenser lens 11 , an insulating glass 12 , a condenser lens 13 and an optical filter 14 . The first light source 1 is red, the second light source 2 is green, and the third pumping beam 3 is blue.

The first half mirror 5 and the second half mirror 6 can rotate around the axis I7 and II8 respectively, and the dark box of the device is provided with a knob that can manipulate the rotating shaft I7 and the rotating shaft II8. .

The first light source 1 , the second light source 2 , and the third pumping light beam 3 are respectively connected to power sources with adjustable power, and the luminous intensity of the light sources can be adjusted individually.

The filters 14 in the first light source 1, the second light source 2, and the third pumping light beam 3 can be replaced at will through the jacks provided on the dark box.

The color lighting device of the present invention changes the angles of the first half-mirror 5 and the second half-mirror 6 through rotation, adjusts the luminous intensity of the first light source 1, the second light source 2, and the third pumping light beam 3 and replaces them. The chromaticity of its optical filter 14 all can change the hue of its mixed light. It is extremely easy to operate during use, and can continuously obtain the desired tone of light.

With reference to Fig. 2, when using this device, its this device dark box 15 can be installed on an auxiliary frame 16, can adjust its three-dimensional direction arbitrarily.
