Detailed Description

The present application will now be described in further detail with reference to the accompanying drawings and specific examples. It is to be understood that the following illustrative embodiments and description are only intended to illustrate the present invention, and are not intended to limit the present invention, and features in the embodiments and examples may be combined with each other in the present application without conflict.

As shown in fig. 1-3, an optional embodiment of the present invention provides a LED lamp shade, including the cover body 1, the top surface of the cover body 1 outwards protrudes and constitutes out the plain noodles 2, the bottom surface middle part of the cover body 1 is sunken to the top surface direction and is formed the chamber 3 that holds that is used for holding the LED light source, the chamber wall that holds the chamber 3 constitutes goes into plain noodles 4, go into plain noodles 4 and be dome-shaped, still be provided with on going into plain noodles 4 and use top central point to disperse the stripe 5 that the spiral extends gradually to the marginal portion as the starting point.

In the embodiment, the light incident surface 4 of the LED lampshade is provided with the stripes 5 which gradually diverge and extend spirally from the top center point as the starting point to the edge, when a plurality of LED light emitting chips in the LED light source emit light simultaneously, part of the light rays are reflected and refracted at the spirally extending stripes 5 and then mixed with the original directly emitted light rays, so that the spatial orientation light color bias generated by the light rays with different colors due to different placement positions is damaged, the color difference is eliminated, and the light color emitted from the light emitting surface is uniform.

In an optional embodiment of the present invention, two stripes 5 are disposed on the light incident surface 4, and both of the stripes extend spirally with the top center point as a starting point and at intervals. The embodiment can uniformly capture more emergent rays by arranging the two spiral extending stripes 5 at intervals, reduces direct emergent rays, ensures that the rays are mixed more fully, and ensures that the emergent light color is more uniform and soft.

In an alternative embodiment of the present invention, the stripe is a concave stripe groove 5 concavely formed on the light incident surface 4. This embodiment is through setting up sunken concave stripe groove 5, and in concave stripe groove 5 was penetrated into to light, can reflect and refract between concave stripe groove 5 both sides limit, makes the light mix more fully.

In an optional embodiment of the present invention, a plurality of convex stripes 6 protruding toward the notch direction are further formed on the bottom wall of the concave stripe groove 5, and the height of the convex stripes 6 is less than the depth of the concave stripe groove 5. This embodiment is through forming a plurality of convex stripes 6 on the groove diapire at concave stripe groove 5 for concave stripe groove 5 is inside different depths everywhere, and when light jetted into concave stripe groove 5 and can receive the influence of convex stripe 6 and carry out many times refraction and or reflection, make light to the random emission of direction of difference, and various colors light is mixed and is closed more fully.

In an optional embodiment of the present invention, the concave stripe groove 5 is a slanted bottom groove that is deep near the center point of the light incident surface and shallow near the edge of the light incident surface. This embodiment sets up to oblique kerve through setting up concave stripe groove 5, and when light jetted into the dark one side of concave stripe groove 5, the reverberation can continue the catadioptric until the light-emitting in the shallow one side of concave stripe groove 5, when the mixed light is abundant, has reduced the light of reflection to light source direction, has increased light-emitting luminous flux.

In an optional embodiment of the present invention, the middle portion of the top surface of the light emitting surface 2 is concave in an arc shape toward the bottom surface of the cover 1, and is formed in a shape with two high ends and a low middle portion in the length direction. The light emitting surface 2 with two high ends and a low middle part can carry out secondary light distribution on emergent rays: in the long side direction of the light emitting surface 2, the light flux distribution is uniformly increased and then decreased from the center to the two sides, and a light distribution curve 7 similar to a bat-shaped light distribution curve with a half-intensity beam angle of 135 degrees is formed; in the short side direction of the light-emitting surface 2, the light flux distribution is uniformly increased and then decreased from the center to the two sides to form a light distribution curve 8 with a half-light-intensity beam angle of 75 degrees similar to an love heart, and finally, a light spot which is approximately rectangular and has uniform surface brightness can be formed on the light-emitting surface 2, so that the light flux output capability of the light-emitting surface 2 is greatly enhanced.

In an optional embodiment of the present invention, a circle of step portions 9 integrally formed with the cover body 1 is further formed at the peripheral edge portion of the cover body 1. When the cover body 1 covers the LED light source, the step portion 9 can be used for arranging an adhesive layer to facilitate the installation of the LED light source.

The embodiments of the present invention have been described with reference to the accompanying drawings, but the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention, and these forms are within the scope of the present invention.
