Technical Field

[0001] This utility model belongs to the field of lighting technology, and in particular relates to an LED power supply housing. Background Technology

[0002] In recent years, due to its advantages such as high energy efficiency, long service life and energy saving and environmental protection, LED lighting has gradually become a new trend in the lighting field. As one of the key components of LED lighting systems, LED power supplies play an important role. Traditional power supply housings are mostly made of metal, and the LED circuit board is installed in the power supply housing to avoid the problem of the LED circuit board falling off the inside of the power supply housing.

[0003] However, in the traditional power supply housing, the LED circuit board needs to be installed by fitting the two mounting brackets of the LED circuit board to the power supply housing. If the LED circuit board is not tightly fitted to the mounting brackets, it will become loose after installation, which will affect the normal use of the LED circuit board. This is to avoid the problem of the electronic components on the surface of the LED circuit board becoming loose due to vibration because the LED circuit board is not installed firmly. Utility Model Content

[0004] This utility model addresses the problem in existing technologies where the LED circuit board needs to be bonded to two mounting brackets on the power supply housing before installation. This can lead to loosening of the LED circuit board after installation if the brackets are not firmly attached, affecting its normal operation. This invention provides a solution to prevent the LED circuit board from becoming loose due to vibration and causing electronic components on its surface to shift.

[0005] An LED power supply housing includes: an LED device housing, an LED device mounting base installed at the bottom of the LED device housing, a positioning ring fixedly installed at the inner bottom edge of the LED device mounting base, a positioning seat slidably connected to the surface of the LED device housing and located at the top of the positioning ring, a slider integrally formed at one end of the surface of the positioning seat, the slider slidably connected to the inner wall of the LED device housing, a screw fixedly connected to the top of one end of the slider, a nut being threaded onto the surface of the screw, and a groove formed on the surface of the LED device housing at the corresponding positions of the slider and the screw.

[0006] As a preferred embodiment of the above technical solution, a plurality of baffles are fixedly connected to the back of the LED device housing, and the interior of the baffles is connected with threaded nails by threads, and the baffles are connected to the LED device mounting base by threaded nails.

[0007] As a preferred embodiment of the above technical solution, a heat-conducting sheet is installed inside the LED device mounting base, and a heat sink is embedded in the bottom of the LED device mounting base. The heat sink and the heat-conducting sheet are in contact, and a plurality of heat sinks are fixedly connected to the bottom of the heat sink, with the heat sinks penetrating the bottom of the LED device mounting base.

[0008] As a preferred embodiment of the above technical solution, both the LED device housing and the LED device mounting base are L-shaped, and the LED device housing and the LED device mounting base are combined to form a cuboid LED power supply housing.

[0009] As a preferred embodiment of the above technical solution, both the LED device housing and the LED device mounting base have several vent holes on their surfaces.

[0010] As a preferred embodiment of the above technical solution, the positioning ring is cylindrical in shape and has a threaded hole inside the cylinder, and the positioning seat has a circular groove with the same diameter as the outer circle of the positioning ring inside.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) By setting the positioning seat as a movable positioning seat, the gap between the positioning seat and the positioning ring can be adjusted. Then, by adjusting the height of the positioning seat, the positioning seat, the positioning ring and the LED circuit board are installed more stably, thereby avoiding the problem that the LED circuit board is not installed firmly and the electronic components on the surface of the LED circuit board become loose due to vibration.

[0013] (2) By installing a heat-conducting sheet inside the LED device mounting base, the heat generated by the LED circuit board is transferred through the heat-conducting sheet when the LED circuit board is installed inside the LED device mounting base, thereby effectively reducing the temperature generated by the LED circuit board during use, thus making the LED circuit board more stable during use.

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example 1

[0023] This utility model provides an LED power supply housing, such as Figures 1 to 6 As shown, it includes an LED device housing 1, an LED device mounting base 2 installed at the bottom of the LED device housing 1, a positioning ring 3 fixedly installed at the inner bottom edge of the LED device mounting base 2, a positioning seat 4 slidably connected to the surface of the LED device housing 1 and the positioning seat 4 is located at the top of the positioning ring 3, a slider 5 integrally formed at one end of the surface of the positioning seat 4, the slider 5 slidably connected to the inner wall of the LED device housing 1, a screw 6 fixedly connected at the top of one end of the slider 5, a nut 7 connected to the surface of the screw 6 by threads, and a groove 8 opened on the surface of the LED device housing 1 at the corresponding positions of the slider 5 and the screw 6.

[0024] like Figures 1 to 4 As shown, several baffles 9 are fixedly connected to the back of the LED device housing 1. Threaded pins are threaded into the interior of each baffle 9. The baffles 9 are connected to the LED device mounting base 2 via these threaded pins. When installing the LED device housing 1 and the LED device mounting base 2, the baffles 9 position the LED device mounting base 2, and the threaded pins are used to install the positioned LED device housing 1 and the LED device mounting base 2. This completes the installation process between the LED device housing 1 and the LED device mounting base 2, making the positioning of the baffles 9 more precise and improving the installation efficiency.

[0025] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, a heat-conducting sheet 10 is installed inside the LED device mounting base 2, and a heat sink 11 is embedded in the bottom of the LED device mounting base 2. The heat sink 11 and the heat-conducting sheet 10 are in contact. Several heat sinks 12 are fixedly connected to the bottom of the heat sink 11. Both the heat sink 11 and the heat sinks 12 are made of thermally conductive metal, such as copper. The heat sinks 12 penetrate the bottom of the LED device mounting base 2. The heat-conducting sheet 10 absorbs the temperature of the LED circuit board surface and transfers it to the surface of the heat sink 11, and then transfers it to the surface of the heat sink 12 through the heat sink 11 for heat dissipation. This effectively reduces the temperature generated by the LED circuit board during use, thereby making the LED circuit board more stable during use.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, both the LED device housing 1 and the LED device mounting base 2 are L-shaped. The LED device housing 1 and the LED device mounting base 2 are combined to form a cuboid LED power supply housing. By installing the LED circuit board inside the LED device mounting base 2 and installing the LED device mounting base 2 and the LED device housing 1, the installation process between the LED device housing 1 and the LED device mounting base 2 is made simpler, thereby improving the installation efficiency between the LED device housing 1 and the LED device mounting base 2.

[0027] like Figures 1 to 5 As shown, both the LED device housing 1 and the LED device mounting base 2 have several vent holes on their surfaces. When the LED circuit board generates heat during use, heat is exchanged through the vent holes on the surfaces of the LED device housing 1 and the LED device mounting base 2, which can reduce the surface temperature of the LED circuit board during use. This avoids the problem of excessive heat generated by the LED circuit board during use, which could lead to damage to the LED circuit board.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the positioning ring 3 is cylindrical with a threaded hole inside. The positioning seat 4 has a circular groove with the same diameter as the outer ring of the positioning ring 3 inside. The positioning ring 3 has a threaded groove inside, and a bolt is threadedly connected through the threaded groove. The LED circuit board is fitted onto the outside of the positioning ring 3. The positioning seat 4 is aligned with the positioning ring 3, and the nut 7 is turned to create a gap between the nut 7 and the LED device housing 1. At this time, the screw 6 is pulled down. The screw 6 moves down, causing the slider 5 to move down. The slider 5 moves down, causing the positioning seat 4 to move down, and the positioning seat 4 is fitted onto the outside of the positioning ring 3. Finally, the bolt is installed inside the positioning ring 3 to fix the positioning seat 4 and the positioning ring 3, thus completing the installation process of the LED circuit board. This makes the installation of the positioning seat 4, the positioning ring 3 and the LED circuit board more stable, thereby avoiding the problem of loose electronic components on the surface of the LED circuit board due to vibration caused by an insecure installation.

[0029] Working principle: The operator installs the heat-conducting plate 10 at the bottom of the LED device mounting base 2 and the LED circuit board at the top of the heat-conducting plate 10. The LED circuit board is positioned by the mounting holes and the positioning ring 3. Then, the LED device housing 1 is installed on the LED device mounting base 2 and the LED device housing 1 slides on the surface of the LED device mounting base 2. The LED device housing 1 drives the baffle 9 to slide on the surface of the LED device mounting base 2. When the baffle 9 and the LED device mounting base 2 are in contact, the installation process between the LED device housing 1 and the LED device mounting base 2 is completed by installing the threaded pins on the surface of the baffle 9 with the LED device mounting base 2. This makes the installation between the LED device housing 1 and the LED device mounting base 2 more accurate by positioning with the baffle 9, thereby improving the positioning process between the LED device housing 1 and the LED device mounting base 2.

[0030] After the LED device housing 1 and the LED device mounting base 2 are installed, the operator rotates the nut 7 to create a gap between the nut 7 and the LED device housing 1. At this time, the screw 6 is pulled down, causing the screw 6 to slide inside the slide groove 8 and drive the slider 5 to move downward. The downward movement of the slider 5 drives the positioning seat 4 to move downward, and the positioning seat 4 and the positioning ring 3 are aligned and fitted onto the outside of the positioning ring 3. Finally, the screw is installed inside the positioning ring 3, and the positioning seat 4 and the positioning ring 3 are fixed, thus completing the installation process of the LED circuit board. Furthermore, by adjusting the height of the positioning seat 4, the installation between the positioning seat 4, the positioning ring 3 and the LED circuit board is made more stable, thereby avoiding the problem of the LED circuit board not being installed firmly, which would cause the electronic components on the surface of the LED circuit board to loosen due to vibration.

[0031] When the LED device housing 1, LED device mounting base 2, and LED circuit board are installed and operated, the end of the installed LED power supply housing with the heat sink 12 is installed at one end of the device's vent. As the surface of the LED circuit board generates temperature, the heat is absorbed by the heat-conducting sheet 10 and transferred to the heat sink 11. The surface temperature of the heat sink 11 is diffused through the heat sink 12, so that when the LED circuit board is installed inside the LED device mounting base 2, the heat generated by the LED circuit board is transferred through the heat-conducting sheet 10, thereby effectively reducing the temperature generated by the LED circuit board during use, thus making the LED circuit board more stable during use.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
