It is applied to the lighting device made by adjusting the light distribution of the light emitting diode. [Prior Art] [0002] As shown in the first figure, a conventional light-emitting diode radium ray is described; a flip-flop illumination device including a light-emitting diode 80 and a counter-body 80 is along the axis of the reticle 81 The heart 82 is outside the reflector 81. The light beam projected by the light-emitting diode 80 and having a large angle with the center @82 forms a light beam with a small angle with the central optical axis 82 through the reflection of the reflector 81, and the light-emitting diode is called the smaller than the curl sleeve 82. The light beam that is not reflected by the reflector 81 is directly projected outward, and the light beam of the light-emitting diode 80 via the reflector 81 and the beam without the reflector 81 can be stacked in the far field to produce a circular cone having a relatively small size. Illumination light shapes, other related patents such as Taiwan Patent Publication No. M332796, M328539, M368767 and US Patent Publication No. US7401 948, US741 1742 B1 and the like all disclose a symmetrical light-emitting diode lampshade, so it is difficult to apply to achieve special lighting needs. , Taiwan Patent No. M33621 1 and US Pat. No. 7,719, 604 B2 disclose a light-emitting diode lighting device that transposes a general light-emitting diode in a light-emitting direction by 90 degrees.

The lampshade cannot be compatible with the light-emitting diode lighting device for the lampshade of the form-replacement page of the form number A0101, page 4/33, October 5, 099. Moreover, it is preferable to achieve a light distribution by plating a metal having a high reflectance, so that it is more expensive than the manufacturing cost of the lampshade integrally formed by the principle of total reflection. U.S. Patent Publication No. US2007/026 3390 A1 discloses a The technique of projecting the beam angle by changing the relative movement of the lampshade along the optical axis is difficult to apply in the case where the mechanism space is limited due to the need to move the lampshade or the light source. Taiwan Patent Publication No. M366083 discloses a lampshade having a light-emitting surface as a bevel type, which is applied to The illumination light pattern produced by the design is less than the asymmetric lampshade of the present case and cannot be used for zooming and changing the light shape. The above various lampshades cannot make a variety of lampshades by the same mold to achieve various special lighting effects. The creator of the case is Overcoming the above prior art problems, a light-emitting diode asymmetrical lampshade, an asymmetrical lampshade applicable rotary zoom technique, and a technique of rotating the asymmetric lampshade to change the illumination light type are created to solve the prior art problems. And apply it to the light-emitting diode lighting device. [New content] [0003] This case is a light-emitting body used to generally refer to any light source with similar illuminating behavior and light source size as the light-emitting diode. [0004] The purpose of the present invention is to provide an asymmetrical lampshade for a light-emitting diode lighting device, which can effectively modulate a light-emitting diode beam into a light distribution range of a near-circular light shape through an appropriate optical design.
