Problems solved by technology
The light emitted by the light source is transmitted through the plexiglass at each hole, so that a light source in the form of a point or spot can be obtained, but because the plexiglass only allows the light to pass through, it cannot better control the light emitted by the light source. Focusing, the brightness of the light spots obtained in this way is not strong, and the lighting effect is poor, and the decoration is weak; in addition, because the lampshade and the plexiglass for light transmission are designed separately, it is inconvenient to install, and the structural stability of the product itself is poor.

Embodiment Construction
[0026] like Figure 1 ~ Figure 3 As shown, a focusing lampshade according to the present invention includes a lampshade body 1, and a plurality of focusing lenses for collecting light emitted by a light source and converging the light to enhance its brightness are integrally arranged on the lampshade body 1 2. The focusing lens 2 can better collect light inside the lampshade, and then focus the collected light through the focusing lens 2 before emitting it, so that what is observed on the projection surface is a point light source or light spot with strong brightness.
[0027] In the present invention, the several focusing lenses 2 are evenly arranged on the lampshade body 1, as Figure 4 , Figure 5 As shown, the focusing lens 2 is a plano-convex lens whose inner wall surface is plane and outer surface is convex. In addition, in the present invention, in order to improve the focus and decoration effect, the inner wall surface of the lampshade body 2 is a blurred surface tha...

The invention relates to the illumination technology field and specifically discloses a focusing lampshade and a manufacturing method thereof. The focusing lampshade comprises a lampshade body which is integrally provided with a plurality of focusing lens used for collecting rays emitted from light source and aggregating the rays so as to increase brightness. The focusing lampshade can better carry out focusing on the light emitted from the luminant light source to gain a plurality of brighter spot light sources or light spots, so as to bring good illumination effect and strong decorative effect. According to the manufacturing method of the focusing lampshade of the invention, the lampshade body and the focusing lens are integrally molded by integral injection molding process. The manufacturing process is simple. The focusing lampshade obtained has good focusing effect.
Description
technical field [0001] The invention belongs to the technical field of lighting products, and in particular relates to a focusing lampshade and a manufacturing method thereof. Background technique [0002] At present, in some places, such as dance halls, gathering places, etc., in order to enhance the atmosphere, the atmosphere is often enhanced by the decorative effect of the lights of the dance hall. In the prior art, in order to diverge the light emitted by the light source from several points, the current common method is to drill several holes through the black spherical lampshade, and then install transparent lamps on each hole correspondingly. plexiglass, and the spherical lampshade and the plexiglass for light transmission were separate designs before. The light emitted by the light source is transmitted through the plexiglass at each hole, so that a light source in the form of a point or spot can be obtained, but because the plexiglass only allows the light to pass...
