[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0024] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the utility model are only for the convenience of clear description, and are not used to limit the scope of the utility model. The change or adjustment of the relative relationship is also considered as the scope of the utility model without substantial change of the technical content.

[0025] Referring to Figures 1-7 A LED ceiling lamp structure with good safety performance, comprising a face cover 1, the face cover 1 is fixedly installed with an inner ring 2, the inner ring 2 is installed with a COB light source, the top of the face cover 1 is provided with a plurality of heat dissipation fins 4, the plurality of heat dissipation fins 4 are integrally formed by aluminum extrusion process, the plurality of heat dissipation fins 4 are arranged in a circle, the heat dissipation area can be increased, air convection is promoted, the heat dissipation fin 4 integrally formed by aluminum extrusion process is closely connected with the lamp body, the structure is stable, the circular arrangement mode makes the heat dissipation fin 4 evenly distributed around the lamp body, can provide support for the lamp body in all directions, effectively disperses the external force borne by the lamp body, reduces the risk of deformation or damage of the lamp body caused by external force.

[0026] The side wall of the face cover 1 is symmetrically fixedly installed with a U-shaped rod 5, the U-shaped rod 5 is sleeved with a torsion spring 6, both ends of the torsion spring 6 are fixedly connected with the surface of the U-shaped rod 5, the torsion spring 6 is fixedly sleeved with a fixed plate 7, the surface of the face cover 1 is symmetrically and obliquely provided with a threaded hole, and the threaded hole is provided with a fixing assembly for assisting the fixation of the ceiling lamp.

[0027] The two fixing plates 7 are initially in contact with the side wall of the cover 1 under the elastic potential energy of the torsion springs 6, and the ends away from the torsion springs 6 are directed downward. When the ceiling lamp needs to be installed, a mounting hole is first formed in the ceiling, then the commercial power L and N poles are respectively connected to the LED power supply L and N poles, the power supply output male line is connected to the LED lamp female line, the threaded cap is tightened, the power circuit is checked, and the correct connection is confirmed. Then, the two fixing plates 7 are controlled to rotate upward until the ends away from the torsion springs 6 are vertically upward. Then, the lamp body is inserted into the mounting hole, the hands are separated from the fixing plates 7, and the fixing plates 7 are inclined to rotate back under the elastic potential energy of the torsion springs 6. The elastic force of the torsion springs 6 can press the hole wall of the mounting hole, and the installation of the lamp and the ceiling is completed. The cover 1 and the ceiling should not have excess gaps, and the power can be turned on.

[0028] When the ceiling lamp needs to be removed from the mounting hole, the ceiling lamp is controlled to move downward, and the two torsion springs 6 and the two fixing plates 7 are brought close to each other under the pressure of the hole wall of the mounting hole until the distance between the two fixing plates 7 is less than the hole diameter of the mounting hole, and the ceiling lamp can be removed from the mounting hole.

[0029] The fixing assembly includes a screw 8 screwed into a threaded hole, an L-shaped rod 9 rotatably installed at the top end of the screw 8, and an insertion block 10 fixedly installed at the end of the L-shaped rod 9. The L-shaped rod 9 is limited in rotation by a limiting component. The limiting component includes a mounting plate 12 fixedly installed on the side wall of the cover 1. The surface of the mounting plate 12 is provided with a through hole. The L-shaped rod 9 is slidably inserted into the through hole. The through hole and the L-shaped rod 9 have the same cross-sectional shape and are not circular. The end of the fixing plate 7 connected to the torsion spring 6 is provided with a socket 11 for the insertion of the insertion block 10.

[0030] After the ceiling lamp is installed in the mounting hole, the two sockets 11 correspond to the positions of the two insertion blocks 10. At this time, the two screws 8 are rotated by a tool to move in the threaded holes, and the L-shaped rod 9 and the insertion block 10 are lifted. After the two insertion blocks 10 are inserted into the two sockets 11, the effect of limiting the mutual approach of the two fixing plates 7 is achieved.

[0031] To avoid the influence of external force, the two torsion springs 6 rotate, and the two fixing plates 7 approach each other. When the two torsion springs 6 are no longer in contact with the hole wall of the mounting hole, and the distance between the two fixing plates 7 is less than the hole diameter of the mounting hole, the fixing effect of the ceiling lamp disappears, and the ceiling lamp falls.

[0032] And in the two block 10 restriction, because two fixed plate 7 can not be close to each other, so as to ensure that the two torsional spring 6 with the hole wall of mounting hole, the pressure on the mounting hole hole wall will not disappear, and the distance between the two fixed plate 7 is always greater than the hole diameter of mounting hole, the ceiling lamp can not be separated from the mounting hole, improve the safety.

[0033] When the need to remove the fixed plate 7 limit, can control screw 8 rotation, make L type rod 9 and block 10 down, until the block 10 from the socket 11 can be removed.

[0034] The lens 3 is fixedly installed at the ring opening of the inner ring 2, and the material of the lens 3 is polymethyl methacrylate. The polymethyl methacrylate has high light transmittance, reduces light loss, improves the lighting efficiency of the lamp, makes the light brighter and more uniform, and has good haze control ability, can scatter light according to the need, makes the lighting effect more soft, avoids dazzling glare, provides a comfortable visual environment, and has excellent mechanical properties and environmental protection and no toxicity.

[0035] In the utility model, through the cooperation between the torsional spring 6 and the fixed plate 7, the ceiling lamp can be quickly installed on the ceiling, the cumbersome steps of using screw and nut fixing parts are avoided, the damage to the ceiling is small, the hole is not needed to be punched in advance, and the fixation is firm and reliable, even if slightly shaken or affected by external force, the elastic force of the torsional spring 6 can always keep the pressure on the ceiling, ensures the fixing effect of the ceiling lamp, and has high safety.

[0036] In the utility model, unless otherwise specified and limited, the terms "installation", "connection", "connection", "fixation" and the like should be understood in a broad sense.

[0037] The above is only the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
