Invention Description: [Fx Ming belongs to the technical field] 'This: The invention patent application relates to a device for selective distribution of the first pass 1 emitted by a light source, which is made of transparent material. And formed into a distribution of internal h-rotating solids, the middle wall material of the crucible and the outer layer are provided with a series of overlapping horizontal refractive ribs, each of which is formed by two oblique intersections. [Prior Art] The present invention is designed to meet the need for illumination, particularly in retail, manufacturing, and exhibition spaces, or any other space requiring high illumination, that is, the need to generate high illumination values in the space in which work activities are performed, and The need to send a small portion of the light in the opposite direction. This need is illustrated in Figure 1, which depicts a polar representation (R.P.) of an example of a luminance distribution produced by a distribution 胄(c) having a photometric center (0). Pass through the horizontal plane of the luminosity center (0) (ρ·〇.). To this end, the luminosity distribution of the light (especially with reference to the high wattage source) has been controlled by a braided distribution having a suitable profile, wherein the source is placed along the mandrel of the distribution. The distributions are made of a non-transmissive material such as a metal having a reflective surface or a transmissive material such as a transparent plastic having a series of vertical 稜鏡 elements on the outer surface. In either case, for two types of distributions, light control Based on the known principle of reflection. 200921009 For the sake of clarity, the operating principles of these two different styles of distribution are illustrated in Figures 2 and 3. In a distribution made of a metal such as aluminum, the reflection effect is produced by the shape and inner surface of the body. The body has a mirror finish. The above is illustrated in Fig. 2, which shows a general ray (A) emitted from the light source (1) at a point (P) illuminating the internal reflection surface of the distribution; reflected light from the point (P) (B) 'It is characterized in that the angle of reflection is equal to the angle of incidence' which is contained between the exit line (Α) and the direction perpendicular to the tangent to the wall of the point (ρ) to the body (C). This style of metal distribution is impaired by its inability to diffuse a suitable amount of luminous flux out of the distribution or upwardly. Also, the pattern made of a translucent transparent plastic (usually an acrylic material or a polycarbonate) is produced by using a reflection 稜鏡 (τ) which is vertically arranged at a substantially 90° degree along the outer surface (SE) of the body (C). Reflection on the surface outside the distribution (known as "total internal reflection"). In this configuration, the vertical curvature of the 稜鏡 completely follows the vertical curvature of the wall of the distribution. In addition to the control determined by the contour of the wall of the distribution, this effect does not allow control of the direction of the light in the vertical plane. Deviations can be obtained at the horizontal plane, but they have a finite effect, which is due to the higher deviation tending to reduce the effect of the main reflection. This is illustrated above in Figure 3, which shows two rays of light emitted by a source (1). As shown in FIG. 3A, the emitted light (a) and the emitted light (b) pass through the transparent wall of the body (c) of the present invention and illuminate the reflected 稜鏡 (τ) to generate reflected light having reflection angles (αΐ and /31) ( Al) and (bl). Figure 3 illustrates the difference between reflected light (al) and (bl) due to the wall of the body (c) at points (P1 and P2) at which the outgoing rays (a) and (b) illuminate the body of the body. The curvature is also due to the different directions of the human rays (1) and (1). In such a body having a vertical reflection 于 on the outer surface, the luminous flux emitted by the light source does not propagate in the space surrounding the body, although it is made of a transparent material; otherwise, the luminous flux is reflected inside the body and Distributed downward according to different directions. There is also a third type of distribution device for the flux of light emitted by the light source. This third type uses a reflective/refractive body made of transparent plastic, which is provided on a surface having a vertical reflective 稜鏡 element (such as 3), and the inner surface is provided on the upper part of the body and is designed to refract light. A series of horizontal slopes. η In this pattern, the refraction produced by the internal refractive element tends to partially alter the reflection produced by the external reflective element, thus allowing partial divergence of light in this limited area of the surface. These optical solutions allow for a higher selective distribution of light compared to 70 solutions based entirely on reflective transmission elements. '", on how, for this third type of distribution, reflection is also the main physical principle for light control, because the refractive element located in the upper region of the wall of the body is only on the wall of the body. The smaller part of the surface is partially repaired. 200921009 - In fact, most of the surface of the body has only the reflection ridges that produce reflections, and the brothers' pieces make the luminosity distribution mainly by the contours of the walls of the distribution body. The reflections produced by the reflective elements are determined and influenced. All of the aforementioned conventional styles are impaired because the light control is primarily determined and adjusted by the contours of the soil of the distribution. In fact, for all such patterns, the curve profile of the wall of the distribution determines the reflection, ^ ^ direction 'this is due to the incident flux on the curved wall of the body according to the incident from the 彳4_ (匕3 in the ray and perpendicular The angle is changed by changing the angle between the + and the directions of the curve wheel of the body wall. i Praise the content] The purpose of the present invention is to select the luminosity distribution of the luminous flux emitted by the source. It allows to obtain selectivity independent of the contour of the wall of the distribution body. The other purpose is to obtain a means for the luminous flux emitted by the light source. ==, which allows the luminosity to pass through the polar curve. The luminous flux is distributed above and below the water surface (ρ·〇). These and other objects have been made from a transparent material of the present invention and formed into a device wherein each of the interior and exterior of the sidewall: the flat refractive rib of the distribution of the twisted solid has a series of overlapping horizontal refractive ribs. 7" The body can be two: inclined and formed. By suitably designing the rim and shape of the inner braid or cylinder. The edge of the rib refracting rib (obtained at the interface edge of the body with the same side of the light source and the outer refractive rib (obtained on the wall of the body opposite to the light source on the wall of 200921009) may be unaffected by the distribution In the case of the influence of the contour of the side walls, a series of combinations are created which are designed to deflect the luminous flux into refractive elements that are upwardly above the horizontal plane and below the horizontal plane. This optical solution is based solely on the refraction of light, wherein the entire side wall The surface and the outer surface are only provided with a refractive transmissive element, which is different from all other conventional patterns having only a reflective prism or a reflective ridge partially associated with the refractive transmissive element. According to this optical solution, for the contour of the wall of the distribution body Each point obtains a plurality of combinations of the angular inclinations of the inclined sides of the outer and inner refractive ribs' such that many directions of the refracted light can be designed in a vertical plane, which is related to the contact angle with the wall of the distribution body and It is roughly 9 inches. (Depending on the material used, there are a few differences) [Embodiment] For the sake of clarity, the apparatus according to the present invention will be described with reference to the accompanying drawings, which are merely illustrative and not restrictive. Referring to Figures 4 and 5, the device of the present invention is applied by The transparent material is made and formed into an example of a distribution (C) having two turns (B1 and B2) at the vertical end. The body (C) has a side wall (p l.), a side wall (pL) Inner surface (SI) and outer surface (s) of sidewall (pl.). As shown in Figures 4 and 4A, the sidewall (pL) has a series of overlaps on the inner surface (sI) and the outer surface (SE). The horizontal refractive ribs, each of which is formed by two intersecting inclined edges, are formed by (Nri), and the external refractive ribs are identified by (nre). In Figure 5, each is formed. The two sloping edges of a rib (NRI) and (NRE) are identified by the letter "F." Figure 5 shows the point at which a pair of opposite refracting ribs (NR丄 and NRE) are emitted by the light source (L) (H) The refraction of the light (RE) of the upper illuminating wall (pl). The tilt of the refracted ray (RR) that propagates out of the side wall (PL) Depending on the slope of the slanted edge of the refractive ribs (NRI and NRE) associated with point (H). The above is illustrated by three graphs 5A, 53 and 5 (the contrast test shows two different refracted rays) (RR1, RR2, and RR3) are generated by three different combinations of the illuminating edges (RE) of the same incident angle using the slanting edges of the refractive ribs (nRI and NRE). Obviously 'for the sidewall of the body (C) (PL) At each point, many combinations are possible. The comparative test of Figures 5A, 5B and 5C shows that the different directions of the refracted light are not dependent on the contour of the side wall (PL) of the body (C), which may not be curved. 'Either in the case of a cone or a cylinder (C). To further clarify the concept, it is noted that the apparatus according to the present invention allows the same luminosity result to be produced from a distribution body (C) having a different profile, or to produce different luminosity results from the same body (C). According to a preferred embodiment of the invention, the inclination of the side of the opposite refractive rib pair (N.R.I. 200921009 and N.R.E.) has a constant value. In this version, the side walls (P.L.) are internally and externally provided with a series of overlapping horizontal annular uniform ribs. In this case, the luminosity distribution will be the same for any radial plane passing through the vertical axis intersecting the center of the light source (L·). Thus, rotating the ring will produce a circular projection with the luminosity distribution shown in Figure 6. According to a more complex embodiment of the invention, the inclination of the inclined sides of the opposite refractive rib pairs (NRI and NRE) is kept constant only for one of the circumferences such that the inclinations have different values in different radial planes, as shown in Fig. 7A. No, it means that it does not correspond to two different radial planes (π" and 笊2) of opposite refractive rib pairs (Nm NR E ) having sides with different inclinations. In this version, the side walls (PL·) are internally and externally provided with a series of overlapping horizontal annular ribs, each of which has a continuous portion having a different configuration at the inclination of the inclined sides of each portion. In this second version, although there is a distribution body (C) having a rotating ring shape, as shown in Fig. 7, an acyclic projection of the luminosity distribution can be obtained. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows the luminosity distribution of light emitted by a distribution having a source of light and the reference level passing through the center of the luminosity (i.e., the boundary between two opposing vertical space segments to be illuminated). Example. Figures 2 and 3 show the light emitted by the light source and the light reflected by the walls of the distribution. 11 200921009 FIG. 3A is a cross-sectional view of FIG. 3 along plane B_B.
