[0019] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present application and not used to limit the present application.

[0020] The embodiment of the present application provides a lighting circuit 1 which can be cut at any position, comprising metal conductors 10, electronic component parts and an insulating base 13.

[0021] The number of the metal conductors 10 is multiple, such as three, four, which are respectively a first metal conductor 100, a second metal conductor 101 and a third metal conductor 102. Each metal conductor 10 is in a strip shape, and the adjacent two metal conductors 10 are arranged side by side and have a preset distance. The distance between the adjacent two metal conductors 10 can be equal or not equal, which is adjusted according to the actual situation. In addition, each metal conductor 10 can be a metal wire or a metal strip, which is adjusted according to the actual situation.

[0022] The electronic component parts comprise a first electronic component part 11 and a second electronic component part 12.

[0023] The number of the first electronic component part 11 is at least one, such as one, two or three. Each first electronic component part 11 comprises an electroluminescent body 110 and a resistor 111. The electroluminescent bodies 110 of each first electronic component part 11 are connected in parallel through the metal conductors 10. The resistors 111 of each first electronic component part 11 are connected in parallel through the metal conductors 10. In each first electronic component part 11, the electroluminescent body 110 and the resistor 111 are connected in series through the metal conductors 10. Therefore, when the first metal conductor 100 and the third metal conductor 102 are connected with two lighting circuit power supply lines respectively, the two electrical connection ends of the electroluminescent body 110 of the first electronic component part 11 can be connected with the first metal conductor 100 and the second metal conductor 101 respectively. The two electrical connection ends of the resistor 111 are connected with the second metal conductor 101 and the third metal conductor 102 respectively. In addition, the electroluminescent body 110 can be a LED (Light Emitting Diode). Each resistor 111 can be an SMD (Surface Mount Device) chip resistor 111.

[0024] The number of the second electronic component part 12 is at least one, such as one, two or three. Each second electronic component part 12 only comprises an electroluminescent body 110. The electroluminescent bodies 110 of each second electronic component part 12 are connected in parallel through the metal conductors 10, and are connected in parallel with the electroluminescent bodies 110 of each first electronic component part 11 through the metal conductors 10. Therefore, the two electrical connection ends of the electroluminescent body 110 of the second electronic component part 12 can be connected with the first metal conductor 100 and the second metal conductor 101 respectively.

[0025] Optionally, in the lighting circuit 1, after setting one first electronic component part 11, at least one (e.g. two) second electronic component parts 12 are set, and then another first electronic component part 11 is set, that is, at least one (e.g. two) second electronic component parts 12 are set between two adjacent first electronic component parts 11. At this time, the electroluminescent body 110 and the resistor 111 of each first electronic component part 11, and the electroluminescent body 110 of each second electronic component part 12 are sequentially arranged in the length direction of the lighting circuit 1, and the electroluminescent body 110 and the electroluminescent body 110 are arranged adjacent to each other, and the electroluminescent body 110 and the resistor 111 are arranged adjacent to each other.

[0026] The insulating base 13 carries the metal conductor 10 and the electronic component part. The insulating base 13 can include a first insulating base (not shown in the figure) and a second insulating base 130. The first insulating base and the second insulating base 130 are respectively located on both sides of the metal conductor layer defined by each metal conductor 10. Optionally, the first insulating base carries the metal conductor 10 first, and then the second insulating base 130 covers the surface of the metal conductor 10. In addition, the first insulating base and the second insulating base 120 can both be insulating films, which can be specifically insulating plastic films, so as to facilitate cutting.

[0027] The second insulating base 130 can have a first hole body 1300, and the number of the first hole body 1300 is at least one, such as one, two, or three. Each first hole body 1300 corresponds to each position on the metal conductor for connecting the electroluminescent body 110 of each electronic component part, such as each position on the first metal conductor 100 for connecting one electrical connection end of the electroluminescent body 110 of each first electronic component part 11 and one electrical connection end of the electroluminescent body 110 of each second electronic component part 12, and each position on the second metal conductor 101 for connecting the other electrical connection end of the electroluminescent body 110 of each first electronic component part 11 and the other electrical connection end of the electroluminescent body 110 of each second electronic component part 12, so that the electroluminescent body 110 is connected (can be soldered) on the metal conductor 10 through the first hole body 1300.

[0028] The second insulating base 130 can also have a second hole body 1301, and the number of the second hole body 1301 is at least one, such as one, two, or three. Each second hole body 1301 corresponds to each position on the metal conductor for connecting the resistor 111 of each electronic component part, such as each position on the second metal conductor 101 for connecting one electrical connection end of the resistor 111 of each first electronic component part 11, and each position on the third metal conductor 102 for connecting the other electrical connection end of the resistor 111 of each first electronic component part 11, so that the resistor 111 is connected (can be soldered) on the metal conductor 10 through the second hole body 1301.

[0029] The second insulating base 130 can further have third hole bodies 1302, the number of which is at least one, such as one, two, or three. Each third hole body 1302 corresponds to a segment of the metal conductor 10 connecting the first power supply line of the lighting circuit between two adjacent electronic component parts, such as a segment of the first metal conductor 100 between two adjacent first electronic component parts 11, two adjacent second electronic component parts 12, or an adjacent first electronic component part 11 and a second electronic component part 12. This allows the third hole body 1302 at the cutting position to form an opening by cutting the lighting circuit 1, and after the opening of the third hole body 1302 of two lighting circuits 1 is abutted to form a new third hole body 1302, the two lighting circuits 1 can be spliced by an electrical connector (which can be solder) arranged in the new third hole body 1302. Each third hole body 1302 can be a strip extending in the same direction as the metal conductor 10.

[0030] The second insulating base 130 can further have fourth hole bodies 1303, the number of which is at least one, such as one, two, or three. Each fourth hole body 1303 corresponds to a segment of the metal conductor 10 connecting the second power supply line of the lighting circuit between two adjacent electronic component parts, such as a segment of the third metal conductor 102 between two adjacent first electronic component parts 11, two adjacent second electronic component parts 12, or an adjacent first electronic component part 11 and a second electronic component part 12. This allows the fourth hole body 1303 at the cutting position to form an opening by cutting the lighting circuit 1, and after the opening of the fourth hole body 1303 of two lighting circuits 1 is abutted to form a new fourth hole body 1303, the two lighting circuits 1 can be spliced by an electrical connector (which can be solder) arranged in the new fourth hole body 1303. Each fourth hole body 1303 can be a strip extending in the same direction as the metal conductor 10.

[0031] The second insulating base 130 can further have connecting hole bodies 1304, the number of which is at least one, such as one, two, or three. Referring to Figure 1, each connection hole body 1304 corresponds to each section of the metal conductor 10 connecting each electroluminescent body 110 between two adjacent electroluminescent bodies 110, for example, each connection hole body 1304 corresponds to each section of the second metal conductor 101 connecting each electroluminescent body 110 between two adjacent electroluminescent bodies 110, so that the lighting circuit 1 can be cut at any position, and any one electroluminescent body 110 or resistor 111 in the case of failure will not affect the lighting circuit 1, and the cutting position of the lighting circuit 1 is between two adjacent electroluminescent bodies 110, and the connection hole body 1304 of the cutting position forms an opening, and the connection of the two lighting circuits 1 at the opening of the connection hole body 1304 of the two lighting circuits 1 forms a new connection hole body 1304. The connection of the two lighting circuits 1 is realized by arranging an electrical connector (which can be solder) in the new connection hole body 1304. Each connection hole body 1304 can be a strip extending in the same direction as the metal conductor 10.

[0032] The number of connection hole bodies 1304 can be more, see Figure 2 , each connection hole body 1304 corresponds to each section of the metal conductor 10 connecting each electroluminescent body 110 between two adjacent electroluminescent bodies 110, between adjacent electroluminescent bodies 110 and resistors 111, for example, each connection hole body 1304 corresponds to each section of the second metal conductor 101 connecting each electroluminescent body 110 between two adjacent electroluminescent bodies 110, between adjacent electroluminescent bodies 110 and resistors 111.

[0033] Through the above setting, the lighting circuit 1 can be cut at any length according to the use environment, and the cutting position can be as shown in Figure 1 .

[0034] The embodiment of the application also provides a lamp strip using the lighting circuit 1 in any of the above embodiments.

[0035] Through the above setting, in the lamp strip, all electroluminescent bodies 110 are connected in parallel, all resistors 111 are connected in parallel, and electroluminescent bodies 110 and resistors 111 are connected in series, so that any one electroluminescent body 110 and resistor 111 in the case of failure will not affect the circuit, and the stability is very high.
