DETAILED DESCRIPTION

[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. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Referring to Figures 1-5 , the utility model provides an embodiment: a LED household lighting lamp of ceiling mounted, including base 1, base 1 bottom fixedly connected with shell one 3, shell one 3 outer wall fixedly connected with fixed part 2, fixed part 2 left side inner wall slidingly connected with spring 12, spring 12 right end fixedly connected with sliding block 16, sliding block 16 right side slidingly connected with shell two 18, shell two 18 surface slidingly connected with sliding part 7, shell two 18 top fixedly connected with limiting part 19, base 1 bottom is provided with heat dissipation mechanism, and heat dissipation mechanism is used to improve the heat dissipation efficiency of device;

[0025] When installing lampshade 6, limiting part 19 makes sliding block 16 to extrude spring 12 inwards to make spring 12 generate elastic force, until limiting part 19 moves to the upper of sliding block 16, sliding block 16 extends under the action of spring 12, and the top of sliding block 16 is attached to the bottom of limiting part 19 to make the position of limiting part 19 fixed, limiting part 19 bottom is fixed with shell two 18, shell two 18 bottom is fixed with lampshade 6, to realize the fixation of lampshade 6, wherein fixed part 2 is provided with sliding block 16 in four directions of front, back, left and right, to provide stable support force for limiting part 19.

[0026] Referring to Figure 3 and Figure 4 , heat dissipation mechanism includes radiator 4, and the fixed connection between radiator 4 and the inner wall of base 1, the bottom of radiator 4 is provided with micro fan 9, and the bottom of radiator 4 is fixedly connected with heat dissipation copper pipe 11.

[0027] Since the LED lamp panel is prone to light decay due to heat accumulation after long-term use, the heat can be transferred by bonding the heat dissipation copper pipe 11 with the LED lamp panel inside the control center 15, the heat conduction of the heat dissipation copper pipe 11 is accelerated by being fixed on the heat sink 4 at the top, and the heat dissipation capacity of the device is further enhanced by providing air cooling for the device through the micro fan 9 installed at the bottom of the heat sink 4, while avoiding the problem of relying on passive heat dissipation when the LED lamp panel is directly bonded to the base 1.

[0028] Referring to Figure 5 , the left end of the spring 12 is fixedly connected with the limiting column 5, the right side of the limiting column 5 is bonded to the surface of the fixed part 2, and the right side of the limiting column 5 is fixedly connected with the connecting column 17, the right end of the connecting column 17 is fixedly connected with the sliding block 16, the connecting column 17 can keep the sliding block 16 stable in the horizontal direction without deviation, thereby assisting the limiting part 19 to fix the position, and the spring 12 is limited by the limiting column 5, so that the spring 12 always expands and contracts in the inner wall of the fixed part 2, and the spring force can be generated under the compression of the sliding block 16.

[0029] Referring to Figure 3 and Figure 4 , the top of the micro fan 9 is fixedly connected with the fixed column 20, the fixed column 20 is fixedly connected between the heat sink 4, and the micro motor is installed in the fixed column 20, the micro motor can control the micro fan 9 to rotate, thereby realizing that when the working environment temperature of the device is low, the micro fan 9 is controlled to stop rotating by the micro motor to save the power consumption of the device.

[0030] Referring to Figure 2 , the bottom of the shell two 18 is fixedly connected with the lampshade 6, the top surface of the lampshade 6 is bonded to the bottom of the sliding part 7, wherein the limiting part 19 and the sliding part 7 are both hollow materials, the limiting part 19, the shell two 18 and the sliding part 7 are all made of polycarbonate material, the polycarbonate material has low density and high temperature resistance, so that the sliding block 16 receives less pressure, the lampshade 6 is made of acrylic plastic material, the acrylic plastic material has good transparency and can soften light, thereby avoiding the phenomenon of glare when the device is used, affecting the use experience of the device.

[0031] Referring to Figure 3 , the surface of the base 1 is provided with a mounting hole 14, and the bottom of the base 1 is fixedly connected with the connecting part 10, the base 1 can be fixed on the ceiling through the mounting hole 14, thereby realizing the ceiling-mounted installation of the device, and since the surface of the connecting part 10 is uniformly provided with the communication port, the airflow can flow through the communication port between the ventilation port 13 and the heat sink 4, thereby dissipating heat inside the device.

[0032] Referring to Figure 2 and Figure 4The bottom of the heat dissipation copper pipe 11 is fixedly connected with a control center 15, and the bottom of the control center 15 is provided with a lamp bead 8. The control center 15 can control the micro fan 9 driven by the residual electricity of the LED driving circuit, so as to improve the power saving capacity of the device. At the same time, the control center 15 can control the brightness change of the lamp bead 8, so that the device can adapt to different use scenes.

[0033] With reference to Figure 4 The left and right sides of the shell 3 are both provided with air vents 13. The air vents 13 are used for assisting the device in heat dissipation. The air vents 13 arranged on the opposite sides can realize the natural circulation of the air inside the device, so that the device can flow caused by the non-uniformity of the air temperature field itself without relying on external force, exchange heat, and improve the heat dissipation capacity of the device.

[0034] Working principle: when the device needs to be removed from the lampshade 6 for cleaning or maintenance, an external force is applied to the lampshade 6 to move the lampshade 6 upward, so that the sliding block 16 is subjected to an outward pushing force. The maximum outer diameter of the sliding member 7 is the same as the outer diameter of the limiting member 19. Since the sliding member 7 is located at the top of the lampshade 6 at this time, the sliding block 16 slides on the surface of the sliding member 7 during the downward movement of the sliding block 16, which causes the spring 12 to be compressed, so that the sliding block 16 can move below the sliding member 7. After the external force on the lampshade 6 disappears, the lampshade 6 starts to move downward due to its own weight. At this time, the sliding block 16 pushes up the sliding member 7 upward, until the top of the sliding member 7 contacts the bottom of the limiting member 19. Since the sliding member 7 cannot continue to move upward at this time, the sliding block 16 slides out from the bottom of the sliding member 7, so that the lampshade 6 is separated from the shell 3, thereby improving the convenience of cleaning or maintenance of the inside of the device.

[0035] In terms of device heat dissipation, the air vents 13 are arranged on the left and right sides of the shell 3, so that the inside of the device can exchange heat by natural convection during use. The heat dissipation copper pipe 11 at the top of the control center 15 dissipates heat for the LED lamp panel inside the control center 15. The heat dissipation copper pipe 11 extends to the bottom of the heat sink 4 to accelerate heat conduction. When the working temperature of the device is relatively high, the control center 15 distributes the residual electricity of the LED driving circuit to the micro motor inside the fixed column 20, so as to drive the micro fan 9 to rotate and start the air cooling mode, thereby further improving the heat dissipation efficiency of the device, so as to avoid the influence of the single heat dissipation path on the service life of the device.

[0036] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
