next, similarly, the lampshade 20 is fixed to rotate clockwise relative to the lamp body 10, when the lampshade 20 and the lamp body 10 are in a non-fastened state, the first rotation preventing member 22 on the bottom surface of the lampshade 20 is located in the counterclockwise direction of the second rotation preventing member 12 of the lamp body 10, by rotating the lampshade 20 clockwise, the first rotation preventing member 22 gradually contacts the second guide surface 120 of the second rotation preventing member 12 through the first guide surface 220, and under the driving of the rotation torque of the lampshade 20, the first rotation preventing member 22 moves over the second rotation preventing member 12 and rotates to the clockwise direction of the stop surface 121 of the second rotation preventing member 12, the first rotation preventing member 22 and the second rotation preventing member 12 interact to block the lampshade 20 from rotating in the direction of being detached from the lamp body 10, that is, the lampshade 20 cannot rotate counterclockwise any more, since the side surface of the second fastening member 11 also stops the connecting portion 210 from further rotating clockwise, the rotation freedom degree of the lampshade 20 is limited, and the fastening portion 211 is fastened to the bottom surface of the second rotation preventing member 11, the lampshade 20 cannot axially detach from the lamp body 10, and the lamp body 10 cannot be fastened to the lamp body 10.

In the embodiment, when the lampshade 20 rotates clockwise relative to the lamp body 10 and is fixed, the first fastener 21 on the bottom surface of the lampshade 20 can be fastened to the second fastener 11 on the inner wall of the lamp body 10, so as to limit the axial detachment of the lampshade 20 from the lamp body 10; meanwhile, the first anti-rotation member 22 on the bottom surface of the lamp housing 20 can pass over the second anti-rotation member 12 on the inner wall of the lamp body 10 to reach the clockwise direction of the second anti-rotation member 12, so as to prevent the lamp housing 20 from rotating in the direction of being separated from the fixed direction of the lamp body 10; meanwhile, the first pressing member 23 disposed on the bottom surface of the lamp body 10 presses the second pressing member 310 on the reflective cup 31 of the light source assembly 30, so that the light source assembly 30 can be effectively limited inside the lamp body 10.

According to the bulb lamp 100 provided by the invention, in the process that the lampshade 20 rotates relative to the lamp body 10, the lampshade 20 and the lamp body 10 are buckled with each other through the first buckling piece 21 and the second buckling piece 11 to limit the axial separation of the lampshade 20 from the lamp body 10, and the lampshade 20 and the lamp body 10 are prevented from rotating through the first anti-rotation piece 22 and the second anti-rotation piece 12, so that the lampshade 20 does not need to rotate; moreover, after the lampshade 20 is rotationally fixed relative to the lamp body 10, the lampshade 20 can abut against the light source assembly 30 to limit the light source assembly 30 inside the lamp body 10, so that the technical problem that the assembly is complicated due to the fact that the light source assembly 30 and the lamp body 10 are fixed through screws in the prior art can be solved.

Of course, in other embodiments, the lampshade 20 can be fixedly connected with the lamp body 10 by rotating counterclockwise.

A fourth embodiment of the present invention provides a bulb lamp, where the bulb lamp 100 shown in this embodiment has a structure substantially similar to the bulb lamp 100 shown in the third embodiment, except that:

in order to ensure the connection stability of the lampshade 20 and the lamp body 10, the plurality of first fasteners 21, the plurality of first anti-rotation members 22, and the plurality of first pressing members 23 are disposed on the inner ring portion 20b of the lampshade 20 and are circumferentially arranged along the inner ring portion 20 b;

similarly, the plurality of second fasteners 11 and the plurality of second anti-rotation members 12 are disposed on the inner wall of the lamp body 10 and are circumferentially staggered along the inner wall of the lamp body 10;

the plurality of second pressing members 310 are circumferentially disposed at the edge of the reflective cup 31 in the light source assembly 30 and extend toward the inner wall of the lamp body 10, and the number of the second pressing members 310 is less than the number of the second fastening members 11 and the second anti-rotation members 12.

In one embodiment, for the convenience of processing with the first fastener 21 and the first anti-rotation member 22, the first pressing member 23 is also disposed on the inner ring portion 20b of the lamp housing 20, and in order to prevent the first pressing member 23 from blocking the light emitted from the light source assembly 30, the first pressing member 23 extends along the axial direction; therefore, in the present embodiment, corresponding to the first pressing member 23 disposed on the inner ring portion 20b and the extending direction thereof, the second pressing member 310 at the edge of the reflective cup 31 extends toward the inner wall of the lamp body 10, i.e. extends toward the outer side of the reflective cup 31, and is located between at least part of the second fastener 11 and at least part of the second rotating member. After the light source assembly 30 is placed in the lamp body 10, the second pressing member 310 at the edge of the reflective cup 31 is located between at least part of the second fastener 11 and at least part of the second anti-rotation member 12; at this time, since the light source assembly 30 has limited the rotational degree of freedom, the second pressing member 310 cannot rotate; in the process of fixing the lampshade 20 and the lamp body 10, the first fastener 21 can avoid contacting the second pressing member 310, and the second pressing member 310 cannot interfere with the extending process and the rotating path of the first fastener 21, so that the first fastener 21 and the second fastener 11 can be normally fastened; meanwhile, the first rotation preventing member 22 can avoid contacting the second pressing member 310, and the second pressing member 310 cannot interfere with the extending process and the rotating path of the second rotation preventing member 12, so that the first rotation preventing member 22 and the second rotation preventing member 12 are matched to prevent rotation; therefore, when the light source module 30 is limited in the rotational freedom and the second pressing member 310 is located between part of the second fastening member 11 and part of the second anti-rotation member 12, neither the first fastening member 21 nor the first anti-rotation member 22 of the lampshade 20 interferes with the second pressing member 310 of the reflective cup 31, so as to avoid the disadvantage that the lampshade 20 cannot be combined with the lamp body 10 due to the structural interference between the light source module 30 and the lampshade 20.

Through carrying out optimization layout to the setting positions of a plurality of first fasteners 21, a plurality of first anti-rotation members 22 and a plurality of first pressing members 23 on the lamp shade 20, carrying out optimization layout to the setting positions of a plurality of second fasteners 11 and a plurality of second anti-rotation members 12 on the lamp body 10, carrying out optimization layout to the setting positions of a plurality of second pressing members 310 on the light source assembly 30, the connection stability of the lamp shade 20 and the lamp body 10 can be effectively ensured, and simultaneously, the lamp shade 20 can be ensured to have good pressing effect to the light source assembly 30.
