Description

Light distributing sheet with several surface composition light distribution curves

technical field

The utility model relates to a light control structure, in particular to a light distribution plate with several surface composition light distribution curves.

Background technique

Lighting lamps are generally divided into two types: indoor and outdoor. Indoor lamps are mainly half-covered (please refer to FIG. 1A ). The surface 103 has a reflective effect. In addition to the light directly irradiated by the light source, there is also a lot of light reflected from the reflective surface 103 to the lighting area. In order to avoid the glare and glare of the light source to the eyes, this type of lamp is usually in the The surface of the light source is atomized to reduce the aforementioned phenomenon.

In consideration of environmental factors, outdoor lamps and lanterns are mainly full-cover lampshades (please refer to Figure 1B), and a light-transmitting cover 104 is installed below (Figure 1A). This cover is used to avoid glare when the eyes look directly at the light source Usually, a number of granular and irregularly arranged micro-bumps (commonly known as frosted glass) are formed on the surface of the illuminant. Both of them have a common disadvantage because the surface is atomized and loses a lot of brightness, and this type of commonly used lamps generally have brightness concentrated in the The Gaussian distribution phenomenon of a block directly below the lamp.

Please refer to Fig. 2, it is a commonly used lamp installed in streets or parks. A lamp 202 is fixed on the top of a light pole 201. There is a light source 203 inside the lamp with the light emitting surface facing upwards. A light-transmitting cover 204 is installed on the light emitting surface of the lamp. The light of the cover body irradiates in all directions, which not only causes poor lighting effect on the road surface, but also causes serious light pollution.

Please refer to Figure 3, which is a common lamp structure designed to avoid light pollution and glare. A lamp 302 is fixed on the top of a lamp pole 301. A light source 303 is inside the lamp with the light emitting surface facing upwards. An oblique reflector is installed above the lamp. The board 304 reflects the light of the lamp to the ground, but it still has imperfections in that the lighting range cannot achieve a wide effect.

In addition, the night reflector of the commonly used road dividing line device is fixed on the lane dividing line with a plastic plate with fluorescent agent components installed in a metal frame. It makes it easy for the driver to distinguish the direction of the lane and the road ahead. The disadvantage is that when the plastic plate with fluorescent agent is covered by dust, its reflective effect will be weakened, or even have no reflective effect at all.

Detailed ways

Please refer to Fig. 4, Fig. 4A and Fig. 4B to illustrate the structure and principle of the present utility model, and in the diagrams, it is illustrated that adjusting the light distribution curve structure on the surface of the light-transmitting plate controls the state of the light traveling path.

Referring to FIG. 4 , a light-transmitting plate 401 with a number of surfaces, when two incident light rays 402 at the same angle enter one surface 403 of the light-transmitting plate 401, refraction occurs and enters the interior of the light-transmitting plate 401, and when it reaches the other surface 404 because of the incident light 402 and the law The included angle of the line 405 is smaller than the critical angle of the light-transmitting plate, so the light-transmitting plate is refracted according to the principle of refraction.

If the angle of the surface 404 in FIG. 4 is adjusted as in the surface 407 of FIG. 4A , the angle between the incident light 402 and the normal 408 is greater than the critical angle of the light-transmitting plate, so that the incident light 402 follows the law of reflection inside the surface 407 ( The angle of incidence is equal to the angle of reflection) and travels to the upper right and reaches another surface 409; at this time, the angle between the incident light 402 and the normal 410 of the surface 409 is smaller than the critical angle of the transparent plate, so the transparent plate is refracted according to the principle of refraction. light sheet.

If the angle of the surface 409 in FIG. 4A is adjusted as shown in the surfaces 411 and 413 of FIG. 4B, the angle between one of the incident light rays 402a and the normal line 412 of the surface 411 is 54.9° greater than the critical angle of the transparent plate, and the incident light ray 402 a is reflected on the inside of the surface 411 and travels to the upper right according to the law of reflection. When it reaches the other surface 415, the angle between the incident light 402a and the normal 416 is smaller than the critical angle of the light-transmitting plate, so the light-transmitting plate is refracted according to the principle of refraction. . The angle between another incident ray 402b and the normal 414 of the surface 413 is 62.3°, which is greater than the critical angle of the light-transmitting plate. The incident ray 402b is reflected on the inside of the surface 413 and travels to the upper right according to the law of reflection, and when it reaches the other surface 415 The included angle between the incident light 402b and the normal 417 is smaller than the critical angle of the light-transmitting plate, so the light-transmitting plate is refracted according to the principle of refraction.

It can be seen that as long as the inclination, curvature and surface area of each surface of the light-transmitting plate with several surfaces are properly adjusted, the traveling path of light and the final irradiation area can be controlled.

Hereinafter, various embodiments of the utility model shown in the drawings will be described.

Please refer to Fig. 5 and Fig. 5A, which is the first embodiment of the light distribution plate with light distribution curve composed of several surfaces of the present invention.

All surfaces of the light-transmitting plate 501 are centered 512 is used as a reference to form an annular light distribution plate. The inclination, curvature and surface area of each surface formed by the light-transmitting plate vary according to the angle at which light incident on the surface is to be refracted or reflected.

Please refer to FIG. 6 , which illustrates the first embodiment of the light distribution plate with several surface composition light distribution curves of the present invention. For controlling the path and result of light irradiation on a predetermined area, when the incident light 602 at the same angle enters the center of the light distribution plate 601 After a surface 603 of the region, all light rays 602 will refract into the light distribution plate 601 at the same angle until the inside of the surface 604 because the incident angle is greater than the critical angle of the light distribution plate, and the light rays 602 will enter the inside of the surface 604 at the same angle as the incident angle. The reflection angle of the angle is reflected to the upper right. When the light 602 reaches the right side, it is incident on surfaces 605, 606, 607, 608, 609, and 610 of different specifications. The light 602 incident on the surface 605 is larger than the light distribution due to the incident angle When the critical angle of the plate is reflected upwards to the top surface 611 again, because the incident angle is smaller than the critical angle of the light distribution plate, the surface 611 is refracted to the predetermined illumination area, and the light 602 incident on the surface 606 is also due to the incident angle greater than When the critical angle of the light distribution plate is reflected upwards to the top surface 611 again, because the incident angle is smaller than the critical angle of the light distribution plate, the surface 611 is refracted to the predetermined illumination area, and the rest of the light is irradiated in the same situation as above. Predetermined lighting area, but each light 602 is incident on surfaces 605, 606, 607, 608, 609, 610 of different specifications, so that the reflection angle of each light 602 is different, and the range 612 after the light is refracted out of the light distribution plate is It can be seen that the utility model has a light distribution plate with several surface composition light distribution curves, which can indeed control the direction of light travel and a specific lighting area, and achieve the effect of wide lighting area and uniform light distribution.

Refraction does not occur until the three surfaces 805, 806, and 807 at the bottom. When the light rays 803 are incident on the inner sides of the three surfaces 805, 806, and 807, the incident angles are all greater than the critical angle of the light distribution plate, so the light distribution is not refracted. The plate 801 reflects the light 803 to the right at three different reflection angles. When it reaches the right surface 808, the incident angles are all smaller than the critical angle. Therefore, according to the refraction principle, the light distribution plate 801 is refracted to the lower right, and the incoming light is refracted when it reaches the surface 809.

The critical angle, so the surface 1008 is refracted to the predetermined illumination area, and the light 1002 incident on the surface 1009 is reflected downwards to the bottom surface 1011 inside the surface 1009 because its incident angle is greater than the critical angle of the light distribution plate, and its incident The angle is smaller than the critical angle of the light distribution plate, so the surface 1011 is refracted to the predetermined illumination area, and the light 1002 incident on the surface 1010 is also because the incident angle is greater than the critical angle of the light distribution plate, so the inner side of the surface 1010 goes downward. It is reflected to the bottom surface 1011, and its incident angle is smaller than the critical angle of the light distribution plate, so the surface 1010 is refracted to the predetermined illumination area. From this figure, it can be seen that the light distribution plate of the present invention has several surface composition light distribution curves, It is possible to control the direction of the light and the specific lighting area, and achieve the effect of wide lighting area and uniform light distribution.
