Technical Field

[0001] The utility model belongs to the technical field of LED constant current power supplies, and in particular relates to a constant current controlled LED power supply. Background Art

[0002] LED constant current power supply is a kind of LED power supply. It is a voltage converter that converts the power supply into a specific voltage and current to drive the LED to emit light. In essence, it uses the device to feedback the current and dynamically adjust the power supply state of the device, so that the current tends to be constant. Usually: the input of the LED driver power supply includes high-voltage industrial frequency AC (i.e., mains), low-voltage DC, high-voltage DC, low-voltage high-frequency AC (such as the output of an electronic transformer), etc. The output of the LED driver power supply is mostly a constant current source that can change the voltage as the forward voltage drop value of the LED changes.

[0003] In existing lamps (such as Figure 5 As shown in the figure, the LED power supply is generally fixed to the lamp holder by screws, but the existing screws are generally small in size, which increases the difficulty of installing the LED power supply. In addition, the existing LED power supply is generally connected to the LED lamp and the mains through a power cord. After the lamp is used for a period of time and is damaged, it is difficult to disassemble the LED power supply, which is not conducive to replacing the LED power supply. Utility Model Content

[0004] The utility model aims to provide a constant current controlled LED power supply to solve the problem that the existing LED power supply installation structure is small in size and not convenient for assembly and disassembly, and that it is difficult to disassemble the power cord of the existing LED power supply after it is damaged.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-3 As shown, the utility model provides a technical solution: a constant current controlled LED power supply, comprising: an LED power supply body 1 with a mounting plate 2;

[0028] A lamp holder 4 is installed below the mounting plate 2, and a plurality of mounting holes 13 are formed on the lamp holder 4;

[0029] Clamps 6 symmetrically mounted on both sides of the mounting plate 2;

[0030] The telescopic mechanism is used to reciprocate and retract the clamp 6, and the telescopic mechanism includes a telescopic rod 7 installed on the inner side of one end of the clamp 6, and second springs 14 symmetrically installed on both sides of the inside of the mounting plate 2. The two second springs 14 are respectively mounted on the telescopic rod 7 on both sides, and the mounting plate 2 is installed on the lamp holder 4 through the clamp 6 and the mounting hole 13.

[0031] Through the above technical solution:

[0032] When the LED power supply body 1 needs to be installed on the lamp holder 4, the two clips 6 on the mounting plate 2 are pushed toward the outside of the mounting plate 2 to adjust the distance between the two clips 6. When the distance between the two clips 6 is equal to the distance between two mounting holes 13 on the lamp holder 4, the two clips 6 are respectively inserted into the two mounting holes 13. At this time, the second spring 14 on the telescopic rod 7 contracts, so that the two clips 6 move to one side of the mounting plate 2, and then the clips 6 are stuck in the mounting holes 13, and finally the mounting plate 2 is installed on the lamp holder 4. When it needs to be removed, the two clips 6 only need to be pushed in opposite directions and the clips 6 are removed from the mounting holes 13 to remove the mounting plate 2 from the lamp holder 4.

[0033] Furthermore, for the telescopic rod 7 set up above, telescopic grooves 12 are opened on both symmetrical sides of the mounting plate 2, and the two telescopic rods 7 are respectively installed in the telescopic grooves 12 on both sides, and the second spring 14 is installed in the telescopic groove 12. The telescopic rod 7 and the second spring 14 are installed inside the mounting plate 2 through the telescopic groove 12, and the telescopic rod 7 can be telescoped on the mounting plate 2, so as to facilitate the adjustment of the distance between the clamp 6 and the mounting plate 2.

[0034] Furthermore, with respect to the above-mentioned clamping member 6, a clamping groove 5 is provided on the inner side of the clamping member 6 away from the end of the telescopic rod 7, and the clamping member 6 is engaged in the mounting hole 13 through the clamping groove 5. The clamping groove 5 on the clamping member 6 facilitates the clamping member 6 to be clamped in the mounting hole 13 on the lamp holder 4, thereby preventing the mounting plate 2 from being separated from the lamp holder 4 without external force.

[0035] Furthermore, for the above-mentioned mounting plate 2, a shock-absorbing pad 3 is installed at the bottom of the mounting plate 2, and the shock-absorbing pad 3 abuts against the lamp holder 4, so that the shock-absorbing pad 3 plays a buffering role between the mounting plate 2 and the lamp holder 4.

[0036] See also Figure 1-2 and Figure 4 As shown, it also includes four wiring mechanisms for conveniently electrically connecting the LED power supply body 1, two of which are installed at the output end of the LED power supply body 1, and the other two are installed at the input end of the LED power supply body 1. The wiring mechanisms include:

[0037] A terminal block 8 is mounted on the mounting plate 2, and a pressing block 18 is installed inside the terminal block 8;

[0038] A pressing mechanism for reciprocatingly lifting and lowering the pressing block 18, the pressing mechanism comprising a baffle 10 mounted above the wiring seat 8, and a fixing rod 16 connected between the baffle 10 and the pressing block 18, a first spring 9 is provided between the baffle 10 and the wiring seat 8, and the first spring 9 is sleeved on the fixing rod 16;

[0039] The wire insertion hole 15 passes through the outer side of the wiring seat 8 and is arranged above the pressing block 18 .

[0040] Through the above technical solution:

[0041] The two wiring mechanisms at the output end of the LED power supply body 1 facilitate electrical connection between the LED and the positive and negative electrodes of the output end of the LED power supply body 1, and the two wiring mechanisms at the input end facilitate electrical connection between the external AC power and the positive and negative electrodes of the input end of the LED power supply body 1. When connecting, it is only necessary to pull the baffle 10 outward to allow the pressing block 18 to rise in the wiring seat 8, and the external power cord is inserted into the wiring seat 8 through the wire plug hole 15. After releasing the pressing block 18, the elastic force of the first spring 9 on the fixing rod 16 is released, so that the pressing block 18 is pressed against the inside of the wiring seat 8 to prevent the power cord from detaching from the wiring seat 8.

[0042] Furthermore, with respect to the terminal block 8 set up as mentioned above, the terminal block 8 is a hollow rectangular cube, and a terminal block 17 is installed at the bottom of the terminal block 8 and below the pressing block 18. One end of the terminal block 17 is electrically connected to the LED power supply, and a handle 11 is installed on the top of the baffle 10. The handle 11 is used to conveniently pull the baffle 10 upward, and the terminal block 17 and the pressing block 18 are conveniently installed inside the terminal block 8 through the terminal block 8. When the pressing block 18 is raised, the external power cord is inserted into the terminal block 8 through the wire plug hole 15. During this process, the power cord is between the pressing block 18 and the terminal block 17. When the pressing block 18 presses the power cord on the terminal block 17, the power cord is restricted from detaching from the terminal block 8, and at the same time, the power cord is electrically connected to the LED power supply body 1 through the terminal block 17.
