[0033] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0034] Example: Please refer to Figure 1 , Figure 2 , Figure 12 to Figure 14As shown, a universal LED lamp installation system includes an installation track 3, a conductive plate 4, an LED lamp 6 and an electronic circuit conversion board 7, wherein the LED lamp 6 has a built-in DC driving power supply 5, two conductive plates 4 and the electronic circuit conversion board 7 are respectively fixedly installed on the installation track 3, and the two conductive plates 4 can be electrically connected to the positive and negative poles of an external DC constant voltage output power supply 8 equipped with a dimmer through wires. The LED lamp 6 can be fixedly installed on the mounting track 3, and the two-pole connectors 9 of the DC driving power supply on the LED lamp 6 can be electrically connected to the two conductive plates 4 on the mounting track 3 respectively. The electronic circuit conversion board 7 is provided with a non-polar positive and negative voltage conversion circuit 10, a constant current output control circuit 11, a dimming circuit 12 and an IC control circuit 13. The non-polar positive and negative voltage conversion circuit and the constant current output control circuit 11 are connected in series to the conductive circuit formed by the two conductive plates 4 and the DC driving power supply on the LED lamp 6. The dimming circuit 12 is connected to the dimming interface of the IC control circuit 13. The signal output interface of the IC control circuit 13 is connected to the DC driving power supply of the LED lamp 6. The dimming circuit 12 can generate an analog dimming signal from the dimming analog voltage output by the dimmer, and output the analog dimming signal to the IC control circuit 13. The IC control circuit 13 outputs a PWM signal to the DC driving power supply of the LED lamp 6.

[0035] The mounting rail 3 can be fixedly connected to the wall 1 or the ceiling 2 through a connecting piece, such as being directly mounted on the wall or ceiling by expansion screws (such as Figures 9 to 11 As shown in the figure), it can also be suspended from the ceiling by means of slings, etc. (as shown in the figure). Figure 8As shown), by setting an electronic circuit conversion board 7 on the mounting track 3, setting a non-polarity positive and negative voltage conversion circuit 10, a constant current output control circuit 11, a dimming circuit 12 and an IC control circuit 13 on the electronic circuit conversion board 7, the two conductive plates 4 are non-polar, and the conductive plates 4 can output current at a constant current, so that the circuit can be suitable for constant voltage output drive, so that the circuit can be compatible with non-dimming, thyristor dimming and 0-10V dimming modes, and the switching and dimming functions can be realized in various dimming modes. When the external DC constant voltage output power supply 8 is not connected to a dimmer, it is a non-dimming mode. When the dimmer is a 0-10V dimmer 14, it is a 0-10V dimming mode, and the dimmer is a thyristor. When the dimmer 15 is on, it is the thyristor dimming mode. No matter what kind of dimmer is connected to the external DC constant voltage output power supply 8, due to the presence of a non-polar positive and negative voltage conversion circuit on the electronic circuit conversion board 7, various lamps with different power requirements on the installation track 3 can be installed on the front and back sides at will without affecting their switching, dimming and lighting functions, thereby realizing the versatility of the LED lamp 6 installation system. Moreover, because of the non-polar conductive plate 4, the lamps can be installed at will, and there is no need to worry about the user damaging the lamps due to reverse connection, which greatly eliminates the poor installation or damage of the lamps caused by human factors. The constant current output to the LED lamp 6 board further protects the service life of the LED lamp 6 beads and reduces the production cost of the LED lamp 6 installation system.

[0036] Please refer to Figure 1 In this embodiment, the non-polarity positive-negative voltage conversion circuit 10 is a bridge rectifier circuit composed of two groups of reverse parallel diodes. The reverse parallel diodes form a bridge rectifier circuit to change the current flow direction, thereby realizing a non-polarity setting in the closed circuit.

[0037] Please refer to the following Figure 2 In this embodiment, the mounting track 3 is formed with an open-shaped slide groove 16 extending along its length direction, and a first magnetic device is fixedly installed on the slide groove 16. The DC driving power supply on the LED lamp 6 can be slidably inserted into the slide groove 16. A second magnetic device is fixedly provided on the DC driving power supply on the LED lamp 6, and the second magnetic device can be magnetically attracted and fixed with the first magnetic device. The two conductive plates 4 are fixedly installed in the slide groove 16, and the two-pole connectors 9 of the DC driving power supply on the LED lamp 6 can be in electrical contact with the surfaces of the two conductive plates 4 in the slide groove 16. During installation, the DC driving power supply of the LED lamp 6 is inserted into the slide groove 16 of the mounting track 3. Under the magnetic attraction of the first magnetic device and the second magnetic device, the DC driving power supply of the LED lamp 6 is fixed in the slide groove 16, and the two-pole connectors 9 of the DC driving power supply of the LED lamp 6 will be tightly against the two conductive plates 4, so that the LED lamp 6 is powered.

[0038] The two-pole connector 9 of the DC driving power supply on the LED lamp 6 is an elastic probe that can be elastically retracted, and the end of the elastic probe can be tightly pressed against the surface of the conductive plate 4 and electrically connected thereto. With the elastic probe that is elastically retractable, after the DC driving power supply is inserted into the slideway, the elastic probe maintains close contact with the conductive plate 4 under the action of elastic force to ensure conduction.

[0039] The surface of the conductive plate 4 is fixedly covered with a layer of insulating pad, and two rows of jacks are arranged at intervals along the extending direction of the slide groove 16 on the insulating pad, and each row of jacks is respectively opposite to a conductive plate 4, and the two-pole connectors 9 of the DC drive power supply can be inserted into the jacks. By covering the surface of the conductive plate 4 with a layer of insulating pad, the conductive plate 4 is protected by the insulating pad, and at the same time, it is prevented that the conductive plate 4 is exposed to the outside, resulting in electric shock to personnel during installation. It is safer for the two-pole connectors 9 of the DC drive power supply to contact the conductive plate 4 after passing through the jacks of the insulating pad, and the jacks also align and position the two-pole connectors 9 of the DC drive power supply.

[0040] A pair of opening slots 17 facing each other in the opening direction are formed on two opposite side walls of the slide groove 16 of the mounting rail 3, and a plug board 18 is removably inserted in the pair of opening slots 17. The electronic circuit conversion board 7 is fixedly installed on the surface of the plug board 18, and two conductive plates 4 are arranged on the surface of the electronic circuit conversion board 7 in parallel and spaced apart. The mounting rail 3 can be made of profiles, and the electronic circuit conversion board 7 is installed on the plug board 18, which is inserted and positioned in the slide groove 16 of the mounting rail 3 by the plug board 18, so as to realize rapid assembly and convenient assembly.

[0041] Please refer to Figure 3 to Figure 6 The two ends of the conductive plate 4 are connected with a male plug 19 and a female plug 20 through wires. The male plug 19 and the female plug 20 on the adjacent mounting rails 3 can be connected and connected, and a space for accommodating the plug and the female plug 20 is formed between the bottom surface of the slide groove 16 and the plug plate 18. The male plug 19 and the female plug 20 are connected to each other to realize the rapid series connection of the conductive plates 4 on the adjacent mounting rails 3. When the rails are connected and assembled, no electrical connectors and middle connectors are required, which can effectively reduce electrical connection components, realize the continuous illumination of the entire rail group, and form continuous illumination.

[0042] Please refer to the following Figure 6 , Figure 7The mounting rail 3 is also provided with a mounting groove 21 extending along its length direction and a connecting and fixing plate 22, and the two ends of the connecting and fixing plate 22 along its length direction are respectively detachably fixed and inserted into the mounting grooves 21 of two adjacent mounting rails 3. By installing the grooves 21 on the mounting rail 3, inserting the two ends of the connecting and fixing plate 22 into the mounting grooves 21 of the adjacent mounting rails 3, and fixing the connecting and fixing plate 22 with the mounting grooves 21 of the mounting rail 3, the adjacent mounting rails 3 can be quickly docked and fixedly positioned. This docking method of the mounting rails 3 is simple, firm, and easy to operate.

[0043] The mounting groove 21 is a closed opening structure with an opening width smaller than the internal width. The connecting and fixing plates 22 are movably screwed with set screws 23 at both ends along the length direction thereof. The ends of the set screws 23 can be tightly pressed against the bottom surface of the mounting groove 21. The heads of the set screws 23 are directly opposite to the opening of the mounting groove 21, and the connecting and fixing plates 22 are tightly pressed against the inner side wall of the opening end of the opening groove. By designing the mounting groove 21 into a closed opening structure, such as a T-shaped opening groove or a C-shaped opening groove in cross section, after the connecting fixing plate 22 is inserted into the mounting groove 21, the fixing screws 23 on the connecting fixing plate 22 are locked through the opening of the mounting groove 21 with a tool, so that the connecting fixing plate 22 and the side wall of the mounting groove 21 maintain a tight connection state. This structure realizes the rapid positioning of the connecting fixing plate 22 and the mounting groove 21 of the mounting rail 3, and after positioning, the adjacent mounting rails 3 can be seamlessly spliced ​​without being affected by the processing errors of the mounting rails 3 and the connecting fixing plate 22. In addition, the mounting rail 3 and the connecting fixing plate 22 can also be fixedly connected by connecting screws and connecting holes 30, or by snap-fitting. This is an equivalent replacement structure that can be easily thought of by technicians in this field based on this patent and falls within the scope of protection of this patent.

[0045] Please refer to Figures 9 to 11The structure of the mounting track 3 being fixedly connected to the wall or ceiling is as follows: a hollow mounting hole 26 is provided on the mounting track 3, and a mounting screw 27 is inserted into the mounting hole 26, and the mounting screw 27 can be fixedly connected to the wall or ceiling. A hollow mounting hole 26 is provided on the mounting track 3, and the mounting screw 27 is inserted into the mounting hole 26 to connect with the wall or ceiling. The mounting hole 26 can extend along the depth direction of the slide groove 16, such as being provided on the bottom surface of the mounting groove 21, and forming a hollow avoidance structure on both the conductive sheet and the plug board 18, or extending in the depth direction of the vertical slide groove 16. Those skilled in the art can set it according to the installation needs.

[0046] Please refer to the following Figure 5 In this embodiment, the mounting rail 3 is also provided with a tail cover 28, which can be detachably fixed to cover the opening surfaces at both ends of the mounting rail 3 along its length direction, and the bottom surfaces at both ends of the slide groove 16 are provided with notches 29 for passing the power line. The two ends of the mounting rail are finally covered by the tail cover 28 to prevent the internal structure of the mounting rail from being exposed, thereby improving the overall aesthetics of the mounting system. Notches 29 are provided on the bottom surfaces at both ends of the mounting rail 3 to facilitate the cables to pass through the notches 29 and connect to the external power supply.

[0047] The side wall of the tail cover 28 is provided with a connection hole 30 and a plurality of inserts 31, and the side walls at both ends of the mounting track 3 are provided with a socket 32 ​​and a threaded hole 33. The inserts 31 can be inserted into the sockets 32 on the side wall of the mounting track 3 in a one-to-one correspondence, and the connection holes 30 on the tail cover 28 are provided with connecting screws, which can be screwed and connected with the threaded holes 33 on the side wall of the mounting track 3.
