Referring to Fig. 1, the mirror-arc triangular prism device of the present invention comprises a mirror-arc prism 33 - 3 , and a rotating shaft 1 - 2 is respectively installed at a center point of both ends of the mirror-arc prism, and the length of the rotating shaft is slightly longer than the length of the mirror-arc prism 1 - 3 Long, and has a positioning interface and interface with the motor, motor 1-1 through the shaft 1 - 2 and mirror arc Degree triple prism 1-3 connection. The motor 1-1 can be a variable speed motor. The controllable speed motor is controlled by an external electric signal to control the motor speed. The motor speed is between 3 rpm and 20 rpm. When the video signal is 30 frames/s, the motor speed is controlled at 10 rpm.

The mirror-arc prism is made of lightweight, high-temperature resistant material with three rectangular faces, each with an angle of 60 degrees. The mirror-arc prism has a length that can be selected between 10mm and 250mm, and a diameter between 10mm and 80mm.

Figure 2 is a side elevational view of a mirrored prism of a mirrored triangular prism in Figure 1. The side of the mirror arc prism is a positive triangle shape, the mirror arc prism 1 - 3 light receiving surface is set to have a high degree of high reflectance mirror 1-4, and the high light reflectivity mirror 1-4 length is substantially the same as the mirror arc prism 1-3 length. And in accordance with the predetermined receiving color visible light row length, except for the high light reflectivity mirror 1-4 having a certain curvature, the other part is coated with non-reflective material or light absorbing material to prevent any residual light from generating reflection and other units.

Fig. 3 is an enlarged view of the high light reflectance orthomorphic mirror surface 1-4 shown in Fig. 2. The high-reflectance arc-shaped mirror consists of three parts, namely, the initial incident curvature mirror surface 1 - 4A3, the incident curvature mirror surface 1-4A2, and the final incident curvature mirror surface 1-4A1, so that the mirror curvature prism 1-3 can produce uniform reflection color. Visible light discharge capacity.

Smooth connection between each part of mirror 1-4 with curvature of high light, ie, the initial incident curvature mirror 1 - 4A3 is smoothly connected with the incident curvature mirror 1 - 4A2, and the incident curvature mirror 1 - 4A2 is smoothly connected with the end incident curvature mirror 1 - 4A1 The initial incident curvature mirror 1 - 4A3, the incident curvature mirror 1 - 4A2 and the final incident curvature mirror 1 - 4A1 together form the arc high gloss reflectivity mirror 1-4, the composition mode is a mirror arc prism prism face plane 1-5 + initial Incident arc mirror 1 - 4A3 + arc mirror 1 - 4A2 + end arc mirror 1 - 4A1 + mirror lobe prism same face 1-5 Plane, mirror arc prism prism face 1 - 5 with incident arc mirror 1 - 4 Α 3 smooth connection, initial incidence curvature mirror 1 - 4 Α 3 with incident arc mirror 1 - 4 Α 2 smooth connection, arc mirror 1 - 4 Α 2 and end incident curvature mirror 1 - The 4A1 smooth connection, the final incident curvature mirror 1-4A1 and the mirror surface roughness prism 1-3 are smoothly connected to the same facet 1-5 plane.

The mirror-arc prisms 1 - 3 are generally clockwise rotated by the motor 1 - 1. If the mirror-arc prism 1-3 is rotated counterclockwise by the motor 1-1, it is necessary to set the radiance high-reflectance mirror on the other side of the mirror-arc prism 1-3 in a clockwise direction, thereby generating reflected color visible light. The direction of the row is just the opposite.

The mirror having a degree of high-light reflectance is composed of three parts, namely, an initial incident curvature of 1 - 4 Α 3 mirror, an incident curvature mirror 1 - 4 Α 2, and an incident curvature Mirror 1 - 4A1, so that the mirror curvature prism 1 - 3 Can produce uniform reflection color visible light arranging ability.

In operation, the motor 1-1 synchronously drives the mirror-arc prism 33- ³ to rotate clockwise at a constant speed. The motor 1-1 can be set according to the AC motor, and the outer casing is set as the stator, and the mirror-arc prism is 1 - 3 The inner set wire is a rotor, which integrates the motor with the mirror-arc prism.

In the case where the curved mirror prisms 1-3 are rotated counterclockwise, it is necessary to change the positions of the mirror-arc prisms 1-3 to the light-receiving surfaces 1-4 so that the reflected light generated is opposite to that of the mirror-arc prisms 1 - 3 clockwise.

The mirror-arc prism 1-3 can be set as a mirror-arc polygon prism 1-3, and the mirror-arc polygon prism 1-3 is composed of a regular polygon to form a mirror-arc polygon facet, and the number of facets of the mirror-arc-poly prism 1-3 should not be greater than 9 faces, that is, less than 9 sides of the regular polygon facet, the reason is that the excessive number of facets caused by the mirror curvature of the polygon mirror 1-3 is too low, which is unfavorable for the reflection of colored visible light rows.

The mirror-arc prism rotates at a constant speed and receives color visible light, color The visible light is output through a mirror-arc prism 33 - 3 with a high degree of light reflectivity mirror 1 - 4 reflection, resulting in a uniform color visible light distribution.

The specific embodiments of the present invention have been described above. However, a person skilled in the art can make various modifications in accordance with the basic idea of the present invention without being limited by the disclosed embodiments, and the modifications are not beyond the scope of the claims of the present invention.
