[0033] As shown in FIG. 1 to FIG. 3, the utility model provides a kind of lighting optimization lamp group, to LED lamp strip for example, including at least two basic units, basic unit includes first wire, second wire and the LED lamp string formed by a plurality of LED lamp beads in series, first wire includes first end 21 and second end 11, second wire includes third end 12 and fourth end 22, and the line resistance between first wire first end 21 and second end 11 is same with the line resistance between second wire third end 12 and fourth end 22, one end of LED lamp string is electrically connected with first end 21, the other end of LED lamp string is electrically connected with fourth end 22, two adjacent basic units are arranged in front and back, and the second end 11 of previous basic unit 1 is electrically connected with the first end 21 of following basic unit 2, the fourth end 22 of previous basic unit 1 is electrically connected with the third end 12 of following basic unit 2, the first end 21 of basic unit located in the foremost end is electrically connected with one of power supply positive pole or negative pole, and the fourth end 22 of basic unit located in the last end is electrically connected with the other of power supply positive pole or negative pole.

[0034] It can be understood that each basic unit includes first wire, second wire and the LED lamp string formed by a plurality of LED lamp beads in series, since the line resistance between first wire first end 21 and second end 11 is same with the line resistance between second wire third end 12 and fourth end 22, same line resistance can ensure that current has same voltage drop when flowing through first wire and second wire, to make current flow through each basic unit keep uniform, this kind of uniform current distribution ensures that each basic unit can obtain same unit of current, so that the brightness of each basic unit is consistent. One end of LED lamp string is electrically connected with first end 21 of first wire, and the other end is electrically connected with fourth end 22 of second wire. Between two adjacent basic units, the second end 11 of previous basic unit 1 is electrically connected with the first end 21 of following basic unit 2, and the fourth end 22 of previous basic unit 1 is electrically connected with the third end 12 of following basic unit 2. This kind of electrical connection mode makes that current can be uniformly distributed between each basic unit. And the first end 21 of basic unit located in the foremost end is electrically connected with one of power supply positive pole or negative pole, and the fourth end 22 of basic unit located in the last end is electrically connected with the other of power supply positive pole or negative pole, so that it ensures that current can flow in from the end of basic unit connected with power supply positive pole, after passing through all basic units, flow out from the other end of basic unit connected with power supply negative pole, to form a complete current loop.

[0035] For example, as shown in the circuit diagram of FIG. 1, LED1 to LED6 are a previous basic unit 1, and LED7 to LED12 are a next basic unit 2. Taking the previous basic unit 1 LED1 to LED6 as an example, the DC+ end-DC1+ end is a first wire, the A end-B end is a second wire, and the DC- end-DC1- end is a third wire 3, wherein the DC+ end is a first end 21, the DC1+ end is a second end 11, the A end is a third end 12, and the B end is a fourth end 22.

[0036] The current flows from the DC+ end of the previous basic unit 1 into the circuit, the previous basic unit 1 is connected in parallel with the next basic unit 2, the DC+ end of the next basic unit 2 is electrically connected with the DC1+ end of the previous basic unit 1, and a part of the current is shunted into the previous basic unit 1. At this time, the current flows in the direction of LED1→R5→LED2→LED3→LED4→LED5→LED6→B end (according to the connection shown in the figure, the B end at this time is the B end of the next basic unit 2)→DC1- end→DC- end.

[0037] It should be noted that only two minimum units are shown in the figure, and the next basic unit 2 also serves as the last end unit. At this time, the B end of the next basic unit 2 needs to be electrically connected with the DC1- end to form a closed loop. In another case, it is assumed that the rear end of the next basic unit 2 shown in the figure is additionally connected with a next basic unit. At this time, the B end is electrically connected with the A end of the next basic unit to make the current flow to the next basic unit.

[0038] According to the above, at this time, the current of the previous basic unit 1 is connected in series with six LED beads and two resistors. Another part of the current is shunted into the next basic unit 2. At this time, the current flows in the direction of R1→LED7→R6→LED8→LED9→LED10→LED11→LED12→B end (according to the connection shown in the figure, the B end at this time is the B end of the next basic unit 2)→DC1- end→DC- end.

[0039] According to the above, at this time, the current of the next basic unit 2 is connected in series with six LED beads and two resistors.

[0040] It is known that the resistance of each LED bead is the same, and it should be noted that all the resistances mentioned above are the line resistance of the wire itself. Therefore, according to the above, under the condition that the voltage of the circuit of the two basic units is consistent, the resistance of each basic unit is consistent, and the current flowing into each basic unit is also consistent. Therefore, the brightness of the LED lights of the previous basic unit 1 and the next basic unit 2 can be kept consistent.

[0041] As shown in Figure 2, a lighting optimization device is also included for use with the lighting optimization lamp group. The lighting optimization device includes a connecting device, which includes a first connector 411 and a second connector 412.

The second connector 412 is used to control the on / off connection between the fourth end 22 of the preceding basic unit 1 and the third end 12 of the following basic unit 2.

[0042] By adding a connecting device between the two basic units, the lighting optimization lamp group can be assembled more quickly and conveniently. It also allows the first connector 411 and the second connector 412 to easily control the connection or disconnection of the electrical connection between the previous basic unit 1 and the next basic unit 2. The connecting device not only realizes the physical connection between the two basic units, but also realizes the electrical connection between the first and second wires of the two adjacent basic units, so that the current can be evenly distributed when flowing through each basic unit, ensuring the consistent brightness of the LED light string.

Alternatively, another connection method can be used: the fourth end 22 of the last basic unit can also be electrically connected to the positive terminal of the power supply through the third conductor 3.

[0044] It also includes a lighting optimization device for use with a lighting optimization lamp assembly. The lighting optimization device includes a connecting device, which includes a plurality of connectors, wherein the first connector 411 is one of the plurality of connectors.

The connecting device not only realizes the physical connection between the two basic units, but also realizes the electrical connection between the first conductive wire, the second conductive wire and the third conductive wire 3 of the adjacent two basic units, so that the current can be uniformly distributed when flowing through each basic unit, ensuring the uniform brightness of the LED lamp string. Furthermore, the fourth connecting piece 414 and the fifth connecting piece 415 make the frontmost basic unit and the last basic unit form a short circuit, so that the entire lighting optimization lamp group forms a closed loop.

[0049] The connecting device includes a connecting body 4 accommodating the second end 11 and the fourth end 22 of the front basic unit 1, the first end 21 and the third end 12 of the rear unit and the connection end points of the third conductive wire 3 of the adjacent two basic units, and the first connecting piece 411, the second connecting piece 412, the third connecting piece 413, the fourth connecting piece 414 and the fifth connecting piece 415 are respectively slidably connected to the top wall of the connecting body 4.

[0050] Further, the connecting body 4 is internally provided with a connecting cavity accommodating the second end 11 and the fourth end 22 of the front basic unit 1, the first end 21 and the third end 12 of the rear unit and the third conductive wire 3, and the two oppositely arranged side walls of the connecting body 4 are respectively provided with a insertion hole 42 for inserting the adjacent two basic units, and the insertion hole 42 is communicated with the accommodating cavity.

[0051] The two oppositely arranged side walls of the connecting body 4 are respectively provided with the insertion hole 42, which is communicated with the connecting cavity, so that the adjacent two basic units can be conveniently inserted into the interior of the connecting body 4 and realize electrical connection in the connecting cavity. This connection mode not only simplifies the connection between multiple basic units, but also avoids complex wiring and connection steps, thereby improving the connection efficiency.

[0052] The insertion hole 42 comprises an avoidance hole 43 for avoiding the LED lamp, the avoidance hole 43 is communicated with the insertion hole 42, which ensures that the basic unit can avoid the LED lamp when inserted into the insertion hole 42, and the avoidance hole 43 can avoid the LED lamp from being squeezed or collided when inserted, thereby protecting the LED lamp from being damaged.

[0053] As shown in FIG. 6 and FIG. 7, the connecting piece comprises a pressing piece 416 and an elastic cantilever 417 connected to the pressing piece 416, and the top wall of the connecting body 4 is provided with a plurality of through holes 44 for the elastic cantilever 417 of the connecting piece to pass through, and the elastic cantilever 417 is in elastic abutment with the inner wall of the through hole 44.

The inner wall of the through hole 44 abuts against the elastic cantilever 417, and when the elastic cantilever 417 of the connecting piece passes through the through hole 44, it has a certain elastic deformation, so that the elastic cantilever 417 is in elastic abutment with the inner wall of the through hole 44. Such a connection mode provides stable connection and ensures firm connection, avoids loose connection under external force, and improves the connection strength of the connecting body 4 and the connecting piece.

[0055] The side of the elastic cantilever 417 abutting against the inner wall of the through hole 44 is provided with a guide slope 418 guiding the elastic cantilever 417 to extend into the through hole 44, and the guide slope 418 is arranged at the lower end of the elastic cantilever 417.

[0056] In order to guide the elastic cantilever 417 to extend into the through hole 44 more easily and gradually abut against the inner wall of the through hole 44 during the extension process, the guide slope 418 is arranged at the lower end of the elastic cantilever 417, and during the extension process of the elastic cantilever 417 into the through hole 44, the guide slope 418 slides along the inner wall of the through hole 44.

[0057] Each connecting piece is provided with two elastic cantilevers 417 elastically abutting against the inner walls of the opposite sides of the through hole 44, and the side of the elastic cantilever 417 abutting against the inner wall of the through hole 44 is further provided with a matching surface 419 abutting against the inner wall of the through hole 44.

[0060] Since the length of the pressing piece is greater than the length of the through hole 44, when the connecting piece is installed in place, the pressing piece will protrude from the top wall of the connecting body 4. This enables the user to operate the pressing piece to make the elastic cantilever 417 slide in the through hole 44, improving the convenience of operation.

[0061] In addition to the preferred embodiments described above, the utility model also has other implementation manners, and all other embodiments obtained by those skilled in the art based on the embodiments in the utility model without creative labor belong to the scope of the utility model claimed.
