Lampshade, processing method thereof and ceiling lamp

Abstract

The invention discloses a lampshade, a processing method thereof and a ceiling lamp. The lampshade comprises a frame and a face cover, wherein a side wall of the face cover is tightly attached to the inner surface of the side wall of the frame, the bottom of the face cover seals the bottom of the frame, and a top opening of the face cover corresponds to a top opening of the frame; an anti-falling part is arranged on the inner surface of the side wall of the frame and is used for being fixedly connected with the mask; and the mask is absorbed to the frame in a vacuum manner. According to the integrated ceiling lamp, the frame and the mask are integrally designed through a blister forming process, so the mask is fixedly connected with the frame through the anti-falling part, and a problem that a gap is likely to be generated between the mask and the frame in a conventional ceiling lamp can be solved. The boss is arranged on the inner surface of the side wall of the frame to serve as the anti-disengaging part, other fixing accessories are not needed, the width of the frame is not limited by the size, and therefore the narrow-frame structural design of the lampshade is achieved.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a lampshade, a processing method thereof, and a dome lamp. Background technique [0002] In the structure of traditional ceiling lamps, the lampshade is an essential component. Generally, the lampshade includes a plastic mask and a metal frame, and both the plastic mask and the metal frame are independent accessories, and the two are combined by means of screws, pressure plates, adhesives, etc., so as to complete the lampshade. [0003] However, both the metal frame and the plastic mask will produce errors during the processing process, resulting in a gap between the metal frame and the plastic mask. The existence of the gap will cause many seemingly small problems that have to be paid attention to . For example: dust intrusion into the lampshade affects the light effect, and may interfere with the light source in the lampshade, affecting the life of the light source. Another ex...

Problems solved by technology

[0003] However, both the metal frame and the plastic mask will produce errors during the processing process, resulting in a gap between the metal frame and the plastic mask. The existence of the gap will cause many seemingly small problems that have to be paid attention to.

For example: dust intrusion into the lampshade affects the light effect, and may interfere with the light source in the lampshade, affecting the life of the light source

Another example: If the gap is uneven, it will affect the appearance quality of the product, resulting in the failure of the lamp to achieve high quality.

[0004] In the existing technology, in order to solve the processing accuracy error of the metal frame and the plastic mask, it is necessary to use special technology and related supporting fixtures, fixtures, inspection tools and labor, thus investing a lot of manpower and material resources and increasing the cost

[0005] On the other hand, ultra-narrow bezel designs are currently popular in the market, but it is difficult to achieve them for traditional ceiling lamps.

Strictly speaking, when considering the design of the narrow frame, it must be considered that the metal frame and the plastic mask are firmly combined, which requires the design of a more complicated fixing structure to be realized

The so-called more complex fixed structure will increase the difficulty of the process, which is not conducive to reducing costs
