[Prior Art] In terms of makeup lamps, aesthetics, safety lighting and high efficiency have become the most basic design requirements. _ Thus, in the part of the security lighting, through the optical system design, such as the traditional parabolic mirror form gradually evolved into multiple mirror form, multi-elliptical mirror form (also known as projection form), free-form mirror form special ' Let the light from the light source be concentrated or diverged by the reflector to change the light distribution to meet the design and specification of the light type (such as concentrated or flat). In particular, with the rapid changes in the characteristics of the light source and the illumination function, the reflector design has been mostly in the form of a free-form mirror to meet the design requirements. > [New content] Therefore, the object of the present invention is to provide a light reflecting seat which can control the reflected light and has a flat shape and a rectangular shape. Thus, the light reflecting seat of the present invention comprises a hollow seat body and a reflecting unit which is arranged in a quadrangularly extending manner on the inner circumferential surface of the hollow seat body. The hollow body has a light entrance port and a light exit port opposite to the light entrance port. The four reflection unit is divided by two imaginary mirrors orthogonal to an optical axis of the hollow body and is continuous mirror symmetry. Each reflection unit includes a distal surface extending from the light entrance to the light exit opening. And a paraxial surface extending from the light entrance port to the light exit opening and located at the other side edge of the far axis surface; one side edge of the far axis surface is located in one of the imaginary On the mirror surface, the paraxial surface is located at the other side edge of the far axis surface, and a side edge away from the far axis surface is located on another imaginary mirror surface; the far axis surface is located at the light exiting The distance between the arc edge and the optical axis is greater than the distance between an arc edge of the light exit opening and the optical axis. φ The effect of the novel is that the four-reflection unit is a continuous mirror symmetry, and a mouth structure, and the distance between the far-axis and the optical axis of each-reflecting unit is different, and the whole form is formed. The light type of the reflected light is a flat rectangular shape. [Embodiment] The foregoing and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments of the accompanying drawings. φ Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals. As shown in FIG. 1 and FIG. 2, a first preferred 'm of the light reflecting seat of the present invention comprises a truncated conical hollow seat i, and a quadruple extending '% like the hollow seat 1 The reflection unit 2 on the inner circumference. The hollow seat body 1 has a - round light human mouth U, and - a light exit port 12 opposite to the light entrance port 11. / Four reflection unit 2 is divided into two imaginary mirrors B and C which are orthogonal to the optical axis 丨 of the hollow seat body, thereby forming a continuous mirror symmetrical structure (ie, any 6 M311850 two adjacent reflection units 2 are It is mirror-symmetrical) and is designed to form a free-form reflector. Each of the reflecting units 2 (see the blackened areas of FIGS. 2 and 2 for convenience of explanation) includes a distal axis curved surface 21 extending from the light incident opening u to the light exit opening 12, and a light incident opening a proximal curved surface 22 extending to the light exit opening 12, a connecting curved surface 23 disposed between the distal axis curved surface 21 and the paraxial curved surface 22, stacked on the distal axis curved surface 21 and substantially truncated A fan-shaped flat-shaped curved block 24, and a corner block 25 which is superposed on the distal-axis curved surface and has a substantially curved cross section. One side edge 214 of the far axis surface 21 is located on the imaginary mirror surface, and the other side edge is adjacent to the paraxial curve 22; and the paraxial surface 22 is away from the far axis surface 21 The side edge 222 is located on the imaginary mirror c. The distal axis surface 21 and the paraxial surface 22 are arcuate arc surfaces centered on the optical axis a, and the arc edge of the distal axis surface 21 located between the optical exit aperture 与 and the optical axis A The distance m is the distance r between the arc edge of the paraxial surface 22 and the optical axis A of the paraxial surface 22. The paraxial surface 22 has three cut faces 221 which are sequentially arranged from the light entrance opening u toward the light exit opening U. The abaxial curved surface 21 has a cut surface portion 213 arranged in the direction from the light exit opening 12 from the two light entrance ports 11; the two cut surface portions 212, 213 are nearly curved smooth, and the = cut face 2U It is floated toward the optical axis A with respect to the cut surface portion 212. The thick meandering block 24 is stacked on one side of the cut surface portion 212. The corner post block 25 is stacked on the other side of the cut surface portion 212: the tip end edge thereof abuts against the meandering curve The block 24 is connected to the (4) face 2ι, and the - 库 库 丨 丨 山 山 山 山 山 山 山 山 山 山 山 山 山 山 山 山 山 山 山 山 端面 端面 端面 端面 端面 端面 端面 端面 端面 端面 端面 端面 端面 端面 端面 端面 端面 端面 端面 端面 端面 端面In this case, when the light of the S light source is bijected through the light entrance port U 2 of the hollow body i, the four reflection unit 2 is in a continuous mirror symmetrical structure, and the near side of the reflection unit 2 has a cutting effect. The axis Φ 22, the connection = face 23, the abaxial surface 21 with a cutting effect, and the embossing effect are all: $ 纟 24 and the embossed effect of the corner block 25 # constructed by the face The reflection effect on the light causes the reflected light passing through the light exit opening to exhibit a flat rectangular shape (as shown by the attachment ι _ ). As shown in FIG. 3, a second preferred embodiment of the present type of light reflecting seat is different in that the light reflecting seat further includes a cover covering the δH hollow body!

A flat surface 32 having an abutting/light exit opening 12 for direct illumination, and a concave surface 33 opposite to the flat surface 32 for light exit. Therefore, the light of the light source is incident from the light-emitting aperture n of the hollow body i, and the free-reflecting surface formed by the four-reflecting unit 2 (see also FIG. 2) reflects and penetrates the light-transmitting plate body 3. At the same time, the plano-concave lens portion 31 of the light-transmissive plate body 3 can further deflect the portion of the light that is penetrated by U, and the distribution of the entire outgoing light can be extended.
