The first refracted ray is incident on the sidewall of the cup-shaped body 9 and the total internal reflection surface 1 〇 generates total internal reflection ray. The reflection ray passes through the peripheral ray exit surface 141 of the ray exit surface 14 . 142. When the light source of the light-emitting diode 20 is at an angle of about 4040 to the optical axis 21, the first refracted light is generated inside the cup-shaped body 9 when the second light incident surface 13 passes, and the first refracted light is incident on the light. The center light exit surface 丨 43, ι 44 of the face 14 produces an outgoing light. The light beam diverging toward the left side of the light-emitting diode 20 is incident on the left half first and second light incident surfaces 121, 131, and the light exit surface 141, 143 at the periphery of the left half and the center is emitted as a concentrated light beam to make the light emitting diode 2〇 The light beam diverging to the left side converges toward the upper central optical axis 21 and becomes divergent to the left side of the optical axis 21. 099114317 Form No. A0101 Page 10/Total 33 page 0992025299-0 201139935 The right side of the optical axis 21 is diverged. The light beam diverging toward the right side of the light emitting diode 20 is incident on the right half first and second light incident surfaces 122, 132 incident on the periphery of the right half and the light exit surface 142 at the center, and 144 is adjusted to diffuse the light beam so that the outgoing light beam remains Diverging toward the right side of the optical axis 21, the concentrated beam and the diffused beam are stacked on each other in the far field illumination range to increase the illuminance. When the lampshade of the first embodiment is installed, the lampshade is placed in front of the light-emitting diode 20, and the left half of the light-emitting diode lighting device is placed above the illumination position. As shown in the tenth figure, the stacked total light distribution can be generated. Wide and flat semicircular light shape with a horizontal direction wider than the vertical direction, and the illumination range is below the central horizontal plane. As shown in the fourth and fifth figures, the second embodiment of the lampshade according to the first embodiment of the present invention has a different surface relationship with respect to the first embodiment on the opposite asymmetric faces. [0030] As shown in the sixth figure, the third embodiment of the lampshade of the present invention utilizes the configuration of the cup-shaped body 9 of the second embodiment, but the first light incident on the light-emitting diode housing portion 11 is incident. A toothed array 17 is partially provided on the face 12. When the light-emitting diode light source passes through the toothed array 17, a multi-refracting effect is generated, and the diffusion angle and uniformity of the diffused light beam of the left half peripheral light exit surface 141 can be increased. As shown in the seventh and eighth figures, the fourth embodiment, which is modified according to the principle of the first embodiment of the present invention, and the first example have different surface relationships on opposite asymmetrical faces, and on the light exit surface 14 of the cup-shaped body 9. The columnar array 18 is locally increased to make the illumination light shape wider and achieve a special illumination effect. The eleventh to fifteenth drawings disclose a rotating zoom principle applied to the illumination of the light-emitting two-pole asymmetric lampshade of the present invention. Device and application in manufacturing 099114317 Form No. A0101 Page 11 / Total 33 page 0992025299-0 [0031] The light-emitting diode asymmetric lampshade of the 201139935 case uses a rotary zoom to change the illumination shape of the light-emitting diode. [0032] The principle of the rotary zoom is as shown in FIG. 11 , which is a light-emitting diode illuminating device having two semi-lenses 23 , 24 placed in front of a light-emitting diode 20 , the first half-lens 23 being placed In the upper half of the optical path, the second half lens 24 is placed in the lower half of the optical path, and the two halves 23, 24 do not overlap along the optical axis, and the position of the light emitting diode 20 is arranged at the focal length of the two half lenses 23, 24. The light passing through the light-emitting diodes 20 of the two half lenses 23, 24 is not refracted to the opposite side, so that the illumination light shape obtained by the illumination device is a circular illumination light shape as shown in the twelfth figure. As shown in the thirteenth aspect, the second half lens 24 of the eleventh figure is flipped 180 degrees to the upper side along the optical axis, so that the two half lenses 23, 24 are overlapped along the optical axis on the upper half side to obtain a ratio of the two halves. Each of the lenses 23, 24 has a single focal length that is shorter than an equivalent focal length, and the focal length change is obtained by the rotation so that the position of the light-emitting body 20 becomes the equivalent focal length of the overlapping two half-lens 23, 24. In addition, the light projected to the upper side of the light-emitting diode 20 is refracted to the lower side by the overlapping two half lenses 23, 24, and the light projected to the lower side of the light-emitting two body 20 does not change the traveling direction because it does not pass through the lens. So that all of the last rays are finally traveled to the lower side to obtain a nearly semicircular illumination pattern as shown in FIG. 14 , and the light of the two light bodies is collected to a smaller illumination area by changing the illumination shape. Greater lighting brightness. As shown in the fifteenth figure, when the half-lens 24 is rotated at different angles along the optical axis, different illumination patterns can be obtained, and different illumination levels can be produced due to different areas of concentrated light. According to the principle of rotary zoom, the case The wrong type of lampshade of the light-emitting diode can use the light-emitting surface with the asymmetrical surface and the relative rotation of the light-incident surface to obtain different illumination effects of different illumination effects. 099114317 Form No. A0101 Page 12/Total 33 Page 0992025299-0 201139935 lampshade. [0033] According to the principle of rotary zoom, the light-emitting diode asymmetric lampshade of the present invention is formed by injection molding, and the mold core for forming the light exit surface having the asymmetric surface is totally reflected with respect to the light having the asymmetric surface. The face or the light incident surface is designed to be rotatable so that a pair of molds can be made into a plurality of lampshades. [0034] According to the principle of rotary zoom, the light exit surface of the asymmetric lampshade is separated into another component, so that the light incident surface and the total light reflection surface can be rotated, and a plurality of illumination shapes can be generated by using a rotating manner. Brightness, to solve the problem of changing the illumination shape and illumination brightness when the device mechanism does not allow the use of moving the lampshade or the light source. [0035] FIG. 16 is a light emitting diode lighting device having a rotatable double asymmetric lampshade, the lighting device comprising two light emitting bodies 20 and two asymmetric light covers 25, 26, the first not The symmetrical lampshade 25 and the second asymmetrical lampshade 26 have the same structure, and the light beam of the light-emitting diode can generate a semi-circular illumination in the lower half of the illumination position through the asymmetric lampshade 25, 26 as shown in FIG. Light shape. As shown in FIG. 18, the second asymmetric shade 27 of FIG. 16 is flipped 180 degrees along the optical axis by a rotating device (not shown) disposed on the lamp cover, such that the second asymmetric type The semicircular illumination pattern caused by the lampshade 27 is inverted from the semicircular illumination pattern of the lower half illumination position to the semicircular illumination pattern at the upper half illumination position, and the illumination light of the lower semicircle generated by the first asymmetric illumination cover 26 Forming a circular illumination shape in the far field as shown in the twentieth diagram, so that the rotation of the second asymmetric pattern 26 can generate a plurality of illumination patterns, such as the twenty-first diagram, which is used to generate Changeable lighting effects. 099114317 Form No. A0101 Page 13 of 33 0992025299-0 201139935 [0036] As shown in the twenty-first figure, the present invention discloses various forms of the asymmetric surface referred to by the asymmetric lampshade of the light-emitting diode of the present invention.
