[Prior Art] φ Since the power consumption of the light-emitting diode ((4)) is far less than that of the conventional filament light bulb, it has always been the direction of people to replace the filament light bulb lighting and promote environmental protection and energy conservation. However, it is indisputable that even now it has greatly improved. The brightness and heat dissipation capability of the light-emitting diode itself, but the small light-emitting diode such as the bean grain has a brightness that is concentrated toward the center of the point; the light quantity is not directional scattering in all directions, and the target object cannot be exclusively directed to the front, with a certain limit range. The lack of scatter beam illumination still relies on the concentrating reticle to control its light quantity to guide the uranium to the range of uranium, in order to obtain sufficient light quantity and light field illumination of the target object. • However, the current spotlight cover for LE:D is mostly a traditional light-transmitting mirror, which is reduced to the corresponding LED size. Although there are also scattered LED lights for illumination, it is not for LED. The illuminant structure is arranged such that the LED illumination range is still insufficiently bundled, and the astigmatism emitted to the side is still concentrated by the concentrating illuminator to the front, and the spotlight cover not designed for LE:D is used to make the illuminating illuminator The astigmatism around the polar body is refracted and the angle is not accurate enough. The whiteness causes the brightness loss of the illumination area. In the case that the light quantity of the LED cannot be effectively bundled, in order to achieve sufficient illumination, the LED with higher power consumption is inevitably used. In order to improve the brightness of the illumination, there is still a problem of improper consumption of the power of 5 M332796. The cloud sees the LED spotlight mask, and there are a few missing faces. Therefore, I am actively improving the way to improve the nine. After some difficult creative process, I finally have this creation. [New content] This creation aims to provide a led wide-angle spotlight cover, which is made of a high-transparent light material (for example, high-brightness optical acrylic PMMA). The bottom of the cover + the central part forms a curved surface of the convex sphere, and the top of the cover forms a flat single convex lens surface, and the peripheral ring of the cover bottom forms a parabolic curved surface (aspherical curvature) of the outward arc convex, and the center of the cover bottom is concavely disposed with the light emitting diode ( The tube hole of LE:D) is configured to cause the light-emitting diode to emit a higher amount of concentrated light toward the front center portion of the cover, and the astigmatism emitted from the light-emitting diode penetrates the tube hole to the parabolic surface, and the light-emitting diode The astigmatism emitted by the body penetrates the cylinder hole to the parabolic surface, and is deflected through the parabolic surface through the parabolic surface. The refracted light that is directed toward the periphery of the parabolic surface is folded out over the cover surface, and the more After the refracted light in the inner surface of the parabolic surface is folded out through the cover surface, the outward expansion is performed, so that the central concentrated light beam in front of the LED is re-applied to about 45 to 65 degrees (according to the selected size ratio and precisely modulated). The broad light field, this is the purpose of creation . Moreover, the LED wide-angle spotlight cover of the present invention can be connected to a light-transmitting tube, and the light-transmissive tube is also made of a high-transparent light material (for example, high-brightness optical acrylic PMMA), and a flat groove is formed on one side tube. The groove is covered with a reflective coating, and when the light-emitting diode emits light toward the end of the light-transmitting tube, the reflected light is continuously generated on the inner wall of the tube, and the light that is incident on the reflective coating is reflected by the reflective coating to achieve light transmission. The whole body of the tube receives light, and emits a bright and bright ray M332796. Finally, it is fused with the central axis ray. The convergence is at the G point as shown in the figure, and the front center position is brightened. In addition, the refracted light is illuminated toward the inner surface of the parabolic surface 14, and then After the plane 12 formed by the top of the cover is folded out, the outer side is expanded outward, so that the light collecting diodes around the center of the front side of the light-emitting diode 3 are surrounded by a wide light field of about 45 to 65 degrees, and there is enough side light. The front end of the LED wide-angle spotlight cover 10 is obliquely incident, and the reverse light coating 51 on the side of the stacked light-transmissive tube 50 is reflected again to form a directional extended illumination. As can be seen from the above, the LE:D wide-angle spotlight cover of the present invention does have the effect of making the amount of light emitted by the LED more concentrated and brightened, and has not been used in public, and is in harmony with the patent law. Quasi-patent is really a virtue. It should be noted that the above is a better embodiment of this creation. If the changes made according to the concept of this creation, or the functional functions produced by them, still do not exceed the spirit of the manual and the illustration, All should be included in the scope of this creation, combined with Chen Ming.
