[0049] Embodiment 3

[0050] See also Figure 1 , Figure 3 , Figure 4 , Fig. 9 and Fig.10, an LED ceiling lamp with good heat dissipation effect and convenient installation, comprising a limiting member 301, wherein one end of the limiting member 301 away from the moving block 302 is fixedly connected to the fixing member 106, and the limiting member 301 limits the position and movement trajectory of the moving block 302;

[0051] Two moving blocks 302 facing each other are clamped inside one end of the limiting member 301. The size of the moving blocks 302 matches the grooves provided on the limiting member 301. The moving blocks 302 limit the position of the positioning ring 303. The movement of the moving blocks 302 drives the positioning ring 303 to move toward each other, thereby engaging.

The inner dimensions of the positioning rings 303 are adapted to the lens 304. The positioning rings 303 define the position of the lens 304. The positioning rings 303 are meshed under the action of the moving blocks 302, so that the lens 304 is in a meshing state. When the positioning rings 303 and the lens 304 are in a meshing state, adjusting the angle of the positioning rings 303 can change the refraction angle of the lens 304, thereby adjusting the lighting efficiency of the downlight 101.

[0053] Two lenses 304 facing each other are meshed inside the two facing positioning rings 303 away from the moving block 302. The lenses 304 mesh with each other. The size of the lenses 304 matches the inside of the positioning rings 303. The lenses 304 are made of transparent material. The lenses 304 mesh under the action of the positioning rings 303.

[0055] Working process and principle: please refer to Figures 1 to 10, an LED ceiling lamp with good heat dissipation effect and convenient installation. The staff will embed the downlight 101 into the driven block 102, and insert the whole device into the hole opened in the ceiling for installing the LED ceiling lamp. At this time, the staff will press the downlight 101, and the driven block 102 will move toward the top of the shell 105 under the action of the downlight 101, thereby driving the block 103 fixedly connected to the driven block 102 to move. The rise of the block 103 will drive the rotating member 104 arranged on the outside thereof to rotate between the shell 105 and the fixing member 106, thereby driving the sponge block 108, one end of which is fixedly connected to the inside of the rotating member 104 and the other end of which is fixedly connected to the inside of the fixing member 106, to move, and clamp the downlight 101 located in the middle of the sponge block 108;

[0056] The downlight 101 drives the driven block 102 to move toward the heat dissipation hole provided on the housing 105, thereby bringing the heating end of the downlight 101 closer to the heat dissipation hole of the housing 105;

[0057] Under the action of the downlight 101, the driven block 102 causes the toggle block 201 inserted in the housing 105 to rotate with the groove provided in the housing 105 as a fulcrum, thereby driving the end of the toggle block 201 located outside the housing 105 to move toward the limit block 205, so that the connecting rod 202 and the intersection end of the toggle block 201 rotate with the intersection end of the connecting rod 202 and the fixing member 106 as a fulcrum, thereby driving the wedge block 203 connected to the connecting rod 202 to move in the opposite direction, and fixing the device in the hole provided in the ceiling;

[0058] The staff installs the downlight 101 on the ceiling, and at this time squeezes the moving block 302 to make the moving block 302 move toward each other. The moving block 302 will drive the two mutually engaged limiting rings to move until the limiting rings are engaged with each other. At this time, the buckle 305 will fix the position of the limiting ring, and the lens 304 set inside the limiting ring will also engage with each other. When in use, the angle of the limiting ring can be adjusted to adjust the lighting efficiency of the downlight 101 through the lens 304. At the same time, the mutually engaged lens 304 and the limiting ring will also protect the downlight 101.

[0059] To sum up, the LED ceiling lamp with good heat dissipation effect and easy installation is that the staff embeds the downlight 101 into the inside of the driven block 102, and stuffs the entire device into the hole opened in the ceiling for installing the LED ceiling lamp. At this time, the staff presses the downlight 101, and the driven block 102 will move toward the top of the shell 105 under the action of the downlight 101, thereby driving the block 103 fixedly connected to the driven block 102 to move, and the rise of the block 103 will drive the rotating member 104 arranged on its outside to rotate between the shell 105 and the fixing member 106, thereby driving the sponge block 108 with one end fixedly connected to the inside of the rotating member 104 and the other end fixedly connected to the inside of the fixing member 106 to move, and clamp the downlight 101 located in the middle position of the sponge block 108, thereby achieving the purpose of preventing the LED ceiling lamp from falling during use.

[0060] When the staff presses the downlight 101, the downlight 101 will drive the driven block 102 to move toward the heat dissipation hole opened on the shell 105, so that the heating end of the downlight 101 is close to the heat dissipation hole of the shell 105, thereby increasing the heat dissipation area of ​​the downlight 101 during use, thereby achieving the purpose of accelerating the heat dissipation of the LED lamp during use.

[0061] The driven block 102 is driven to move by the downlight 101. Under the action of the downlight 101, the driven block 102 causes the toggle block 201 inserted in the shell 105 to rotate with the groove opened in the shell 105 as a fulcrum, thereby driving the end of the toggle block 201 located on the outside of the shell 105 to move toward the direction of the limit block 205, so that the connecting rod 202 and the intersection end of the toggle block 201 rotate with the intersection end of the connecting rod 202 and the fixing member 106 as a fulcrum, thereby driving the wedge block 203 connected to the connecting rod 202 to move in the opposite direction, fixing the device inside the hole opened on the ceiling, thereby achieving the purpose of convenient installation and disassembly of the LED ceiling lamp.

[0062] The staff installs the downlight 101 on the ceiling and squeezes the moving block 302 to make the moving block 302 move toward each other. The moving block 302 will drive the two mutually engaged limiting rings to move until the limiting rings are engaged with each other. At this time, the buckle 305 will fix the position of the limiting rings, and the lenses 304 arranged inside the limiting rings will also engage with each other. When in use, the angle of the limiting rings can be adjusted to adjust the lighting efficiency of the downlight 101 through the lens 304. At the same time, the mutually engaged lens 304 and the limiting ring will also protect the downlight 101, thereby achieving the purpose of conveniently adjusting the lighting efficiency of the LED ceiling light and protecting the LED ceiling light.

2. According to claim 1, the LED ceiling lamp with good heat dissipation effect and convenient installation is characterized in that: The limiting block (205) is fixedly connected to the housing (105) at one end away from the connecting rod (202).

3. According to claim 1, the LED ceiling lamp with good heat dissipation effect and convenient installation is characterized in that: Two lenses (304) facing each other are engaged inside the two facing positioning rings (303) on the side away from the moving block (302).

4. The LED ceiling lamp with good heat dissipation effect and convenient installation according to claim 1, characterized in that: The outer side of one set of the positioning rings (303) is hinged with two buckles (305) facing each other.

5. The LED ceiling lamp with good heat dissipation effect and convenient installation according to claim 1, characterized in that: One end of the limiting member (301) away from the moving block (302) is fixedly connected to the fixing member (106).
