Description

Technical Field

[0001] The utility model relates to the field of lamp lighting, in particular to a magnetic LED lamp. Background Art

[0002] LED lamps use solid semiconductor chips as luminescent materials. In semiconductors, excess energy is released through carrier recombination, causing photon emission, and directly emitting red, yellow, blue, green, cyan, orange, purple, and white light. LED lighting products are lighting fixtures made using LED as a light source. LED technology began in the 1950s and 1960s and has been widely used in industrial production and family life, such as electronic watches, digital multimeters, LED liquid display televisions, microcomputer liquid crystal displays, traffic lights, etc. The application examples are too numerous to mention. Now the high-power LED lighting source series products developed by scientific and technological personnel have passed the appraisal, filling the gap in such products in China, and thus opening up the situation and starting to develop towards industrialization.

[0003] However, in the prior art, since the magnetic attraction force of the magnetic lamp is relatively strong during assembly, when the magnetic lamp is peeled off from the wall surface, it is very easy for the lamp body to contact the wall surface, thereby causing the wall surface to be scratched due to pressure.

[0011] Preferably, the through hole and the limit spring are located on the same axis.

[0012] Preferably, the size of the through hole is adapted to the top wall column sleeved with the sponge sleeve.
