Description

Technical Field

[0001] The present application relates to the technical field of LED lamps, and in particular to a foldable LED lamp. Background Art

[0002] LED lights are energy-saving and efficient electric light sources. When electrons pass through semiconductor chips encapsulated in epoxy resin, negatively charged electrons recombine with positively charged holes on the chips and disappear, while photons are generated. Compared with traditional incandescent lamps and fluorescent lamps, LED lights have the characteristics of high luminous efficiency, low heat generation, not easy to damage, long life, and easy to make special shapes. Therefore, LED lights are currently widely used in lighting in various fields.

[0003] In the field of wall-mounted table lamps, there is usually a problem of limited illumination range of the light. The traditional solution is to set a lampshade with a conical cylindrical structure. Although this lampshade can improve the focusing effect, it not only takes up a lot of space when not in use, but also easily accumulates dust. There are also some foldable wall-mounted LED lamps in the prior art, but these LED lamps can only lengthen the length of the LED lamps and change the illumination position after unfolding. Therefore, we propose a new type of LED lamp that can be folded and can expand the illumination area after unfolding. Summary of the invention
