DETAILED DESCRIPTION

[0037] 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.

[0038] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0039] In the first aspect, the embodiment of the utility model provides an infinite dual-color flash cannon, Figure 1 Schematic diagram of the structure of the stepless two-color flash cannon provided by the embodiment of the utility model, such as Figure 1 As shown, the infinite two-color flash cannon includes:

[0040] The chip 211 , the first light emitting diode element 212 and the second light emitting diode element 213 are built in.

[0041] The built-in chip 211 includes a first input terminal 2111, a second input terminal 2112, a first output terminal 2113 and a second output terminal 2114. The first input terminal 2111 and the first output terminal 2113 are electrically connected, and the second input terminal 2112 and the second output terminal 2114 are electrically connected.

[0042] The anode of the first LED element 212 is electrically connected to the first output terminal 2113 , the cathode of the first LED element 212 is electrically connected to the second input terminal 2112 , the anode of the second LED element 213 is electrically connected to the second output terminal 2114 , and the cathode of the second LED element 213 is electrically connected to the first input terminal 2111 .

[0043] When the first input end 2111 is powered on, the first light emitting diode element 212 emits light, and when the second input end 2112 is powered on, the second light emitting diode element 213 emits light.

[0044] It can be seen from the above embodiments that in the embodiment of the utility model, since the built-in chip 211 includes a first input terminal 2111, a second input terminal 2112, a first output terminal 2113 and a second output terminal 2114, the first input terminal 2111 and the first output terminal 2113 are electrically connected, the second input terminal 2112 and the second output terminal 2114 are electrically connected, the anode of the first light-emitting diode element 212 and the first output terminal 2113 are electrically connected, the cathode of the first light-emitting diode element 212 and the second input terminal 2112 are electrically connected, and the anode of the second light-emitting diode element 213 and the second output terminal 2114 are electrically connected. 14 is electrically connected, the cathode of the second light emitting diode element 213 is electrically connected to the first input end 2111, so when the first input end 2111 is powered on, the first output end 2113 is powered on, and then the anode of the first light emitting diode element 212 electrically connected to the first output end 2113 is powered on, so that the first light emitting diode emits light, and when the second input end 2112 is powered on, the second output end 2114 is powered on, and then the anode of the second light emitting diode element 213 electrically connected to the second output end 2114 is powered on, so that the second light emitting diode emits light. In summary, in the embodiment of the utility model, the electrodeless two-color flash cannon uses only one built-in chip 211, that is, it can achieve the effect of multi-effect flashing, and does not need to be equipped with a voltage regulator tube, so that the production cost of the electrodeless two-color flash cannon can be reduced and the production efficiency can be improved.

[0045] It should be noted that in the above embodiment, the built-in chip 211 can be any one of a light-emitting diode chip, a packaging chip, and a control chip, and the embodiment of the utility model does not limit this. Taking the control chip as an example, the control chip can be any one of a light-emitting diode driver chip, an intelligent control chip, a sensor chip, and the like. The light-emitting diode driver chip can control the brightness and color of the first light-emitting diode element 212 and the second light-emitting diode element 213, the intelligent control chip can realize functions such as intelligent interconnection, and the sensor chip can sense changes in the surrounding environment. Through the application of the above chips, the infinite two-color flash cannon is more intelligent and energy-saving, meeting people's high-quality lighting needs.

[0046] In addition, the first light-emitting diode element 212 and the second light-emitting diode element 213 both emit light through the release ability of electrons and holes. Taking the first light-emitting diode element 212 as an example, the core part of the first light-emitting diode element 212 is a wafer composed of a P-type semiconductor and an N-type semiconductor, and there is a transition layer between the P-type semiconductor and the N-type semiconductor, which is called a PN junction. When the injected minority carriers recombine with the majority carriers, the excess energy will be released in the form of light, thereby directly converting the electrical energy into light energy. When a reverse voltage is applied to the PN junction, it is difficult for minority carriers to be injected, so no light is emitted. When the first light-emitting diode element 212 is in a forward working state (i.e., a forward voltage is applied to both ends), when the current flows from the anode of the first light-emitting diode element 212 to the cathode, the semiconductor crystal emits light of different colors from ultraviolet to infrared, and the intensity of the light is related to the current. In other words, in the embodiment of the utility model, only when the first input terminal 2111 of the built-in chip 211 is powered on, the first output terminal 2113 has a positive current input, so that the current flows from the anode of the first light-emitting diode element 212 to the cathode, so that the first light-emitting diode element 212 emits light. Since the second input terminal 2112 is electrically connected to the cathode of the first light-emitting diode element 212, when the second input terminal 2112 of the built-in chip 211 is powered on, the PN junction of the first light-emitting diode element 212 is applied with a reverse voltage, and it is difficult for minority carriers to be injected, so the first light-emitting diode element 212 does not emit light. The working principle of the second light-emitting diode element 213 is consistent with the working principle of the first light-emitting diode element 212, and the embodiment of the utility model will not be repeated.

[0047] In a second aspect, the present utility model also provides a light emitting diode light string, such as Figures 2 to 4 As shown, the LED light string includes a plurality of LED light groups 1 connected in series in sequence, wherein at least one LED light group 1 among the plurality of LED light groups 1 includes at least one electrodeless two-color flash cannon 21 described in the first aspect.

[0048] It should be noted that in the above embodiment, the LED light group 1 included in the LED light string can include only the electrodeless two-color flash cannon 21, that is, the entire LED light string is an electrodeless two-color flash cannon 21. The LED light group 1 included in the LED light string can also include a certain proportion of forward and reverse lamp beads 31 and electrodeless two-color flash cannon 21, or part of the LED light group 1 included in the LED light string is a light group that only includes the electrodeless two-color flash cannon 21, and the other part is a light group that only includes the forward and reverse lamp beads 31. The embodiment of the utility model does not limit this. In this way, the LED light string can be equipped with different structural compositions according to the functional needs of the LED light string. This makes the lighting effects of the LED light string more diverse.

[0049] It can be seen from the above embodiments that since the LED light string includes a plurality of LED light groups 1 connected in series, and at least one of the plurality of LED light groups 1 includes at least one electrodeless two-color flash cannon 21 as described in the first aspect, the LED light string at least has the electrodeless two-color flash cannon 21. In addition, since the electrodeless two-color flash cannon 21 uses only one built-in chip 211, it can achieve a multi-effect flashing effect, and does not need to be equipped with a voltage regulator tube, which reduces the production cost of the electrodeless two-color flash cannon 21 and improves the production efficiency. Therefore, the production cost of the LED light string can be reduced, and the market competitiveness is correspondingly improved.

[0050] Furthermore, with regard to the specific structure of the LED light string, in some embodiments, the LED light string also includes a power adapter 4 and a light string controller 5 electrically connected to the output end of the power adapter 4; the input end of the power adapter 4 is used to connect to the AC power network, and the light string controller 5 includes an electrical input end 51 and a signal output end 52, and the electrical input end 51 is electrically connected to the output end of the power adapter 4; the signal output end 52 includes at least two output endpoints, one of the at least two output endpoints is connected to the first LED light group 1 among the multiple LED light groups 1, and the other of the at least two output endpoints is connected to the last LED light group 1 among the multiple LED light groups 1.

[0051] It should be noted that the power adapter 4 is used to provide the low-voltage direct current required by the light-emitting diode light string. The input end of the power adapter 4 is used to connect to the mains network. The output of the mains network can be 220 volt single-phase alternating current or 110 volt single-phase alternating current. The output end of the power adapter 4 is used to connect to the electrical input end 51 of the light string controller 5, and is used to provide 6 volt to 36 volt direct current to the light string controller 5. In addition, the signal output end 52 of the light string controller 5 is used to electrically connect multiple light-emitting diode light groups 1. Specifically, the signal output end 52 may include two output endpoints, or may include four output endpoints, or other even number of output endpoints, which is not limited in the embodiment of the utility model. The signal output end 52 is used to output a pulse signal with a preset variable duty cycle and a variable frequency according to its circuit properties. The pulse signal may also be a variable duty cycle and a fixed frequency, or a fixed duty cycle and a variable frequency. Taking the signal output terminal 52 including two output endpoints as an example, one of the two output endpoints is connected to the first LED light group 1 among the multiple LED light groups 1, and the other of the two output endpoints is connected to the last LED light group 1 among the multiple LED light groups 1. In this way, when one of the two output endpoints is powered on, the LEDs in the LED light group 1 that are powered on in the forward direction emit light, and when the other of the two output endpoints is powered on, the LEDs in the LED light group 1 that are powered on in the reverse direction emit light.

[0052] Optionally, the light string controller 5 includes at least one of a hand-pressed controller, a foot-operated controller, an infrared remote control controller, a wireless video remote control controller, a Bluetooth remote control controller, and a wireless fidelity remote control controller.

[0053] It should be noted that the circuit diagrams of the hand-operated controller and the foot-operated controller are as follows: Figure 5 As shown, infrared remote control, wireless video remote control, Bluetooth remote control and wireless fidelity remote control are as follows Figure 6 and Figure 7 shown.

[0054] In some embodiments, a plurality of LED light groups 1 are arranged in a predetermined shape.

[0055] It should be noted that since multiple LED light groups 1 are arranged in preset shape patterns, the LED light string can present different preset shape patterns, so that the LED light string can adapt to different application scenarios, making the lighting effects of the LED light string more diverse.

[0056] Optionally, the preset shape pattern is any one of a bar, a ring, a character or an object outline shape. In this way, a suitable outer shape contour of the LED light string can be selected based on the application scenario of the LED light string.

[0057] For the signal control of the LED light string, in one possible implementation, such as Figure 2 As shown, the signal output terminal 52 includes a first output terminal and a second output terminal; each LED lamp group 1 includes forward and reverse lamp beads 31 and an infinite two-color flash cannon 21 in parallel, the first input terminal is connected to the first LED lamp group 1 among the multiple LED lamp groups 1, and the second input terminal is connected to the last LED lamp group 1 among the multiple LED lamp groups 1.

[0058] It should be noted that the forward and reverse lamp beads 31 can be two parallel forward and reverse conductive LED lamp beads and reverse conductive LED lamp beads, or a single forward and reverse bidirectional LED element, and the luminous color of the forward and reverse lamp beads 31 can be white, warm white, red, green, yellow, blue, pink or purple, or other colors, which are not limited in the embodiment of the present invention. Based on this, in the signal control structure of the above-mentioned LED light string, the first input terminal and the anode of one LED in the forward and reverse lamp beads 31 in the first LED light group 1 among the multiple LED light groups 1 are electrically connected to the first input terminal 2111 of the electrodeless two-color flash cannon 21, and the second input terminal and the anode of another LED in the forward and reverse lamp beads 31 in the last LED light group 1 among the multiple LED light groups 1 are electrically connected to the second input terminal 2112 of the electrodeless two-color flash cannon 21. In this way, when the first input terminal is powered on, the LED in the LED light group 1 powered on in the forward direction is made to emit light, and when the second input terminal is powered on, the LED in the LED light group 1 powered on in the reverse direction is made to emit light. Driven by the pulse signal of the light string controller 5, the forward and reverse lamp beads 31 and the infinite two-color flash cannon 21 can achieve multiple effects flashing, so that the light emitting diode light string can achieve better decoration and display effects. Figure 2 As shown in L1 in the figure, the second input terminal is Figure 2 As shown in L2.

[0059] For the signal control of the LED light string, in another possible implementation method, such as Figure 3As shown, the signal output terminal 52 includes a third output endpoint, a fourth output endpoint, a fifth output endpoint, and a sixth output endpoint; the light emitting diode lamp string includes a first lamp string 2 and a second lamp string 3, the first lamp string 2 includes a plurality of flashing cannon lamp groups connected in series in sequence, the second lamp string 3 includes a plurality of constantly lit cannon lamp groups connected in series in sequence, each flashing cannon lamp group includes a plurality of parallel-connected electrodeless two-color flashing cannons 21, and each constantly lit cannon lamp group includes a plurality of parallel-connected forward and reverse lamp beads 31; the third output endpoint is connected to the first constantly lit cannon lamp group of the plurality of constantly lit cannon lamp groups, the fourth output endpoint is connected to the last constantly lit cannon lamp group of the plurality of constantly lit cannon lamp groups; the fifth output endpoint is connected to the first flashing cannon lamp group of the plurality of constantly lit cannon lamp groups, and the sixth output endpoint is connected to the last flashing cannon lamp group of the plurality of flashing cannon lamp groups.

[0060] It should be noted that, in this embodiment, the LED light string includes two types of light strings, namely, a light string including only flashing light groups and a light string including only permanent light groups, further enriching the lighting effects of the LED light string. Specifically, in the above embodiment, the third output terminal is connected to the first permanent light group of the plurality of permanent light groups, and the fourth output terminal is connected to the last permanent light group of the plurality of permanent light groups, so that when the third input terminal is powered on, the forward-powered LEDs in the permanent light group emit light, and when the fourth input terminal is powered on, the reverse-powered LEDs in the permanent light group emit light. The fifth output terminal is connected to the first flashing light group in the plurality of permanent light groups, and the sixth output terminal is connected to the last flashing light group in the plurality of flashing light groups, so that when the fifth input terminal is powered on, the first LED in the flashing light group that is in the same circuit as the first input terminal 2111 emits light, and the second LED in the flashing light group that is in the same circuit as the second input terminal 2112 emits light. In this way, more types of light flashing effects can be achieved by alternating between the flashing light group and the constant light light group. In addition, if either the first light string 2 or the second light string 3 is damaged, it will not affect the normal display of the other light string, which is beneficial to reduce the failure rate of light display and facilitates later maintenance. Figure 3 As shown in L3 in FIG. 1 , the fourth input terminal is as follows: Figure 3 As shown in L4 in the figure, the fifth input terminal is Figure 3 As shown in L5 in FIG. 1 , the sixth input terminal is as follows: Figure 3 As shown in L6.

[0061] Regarding the structure of the LED lamp group 1, in one possible implementation, the LED lamp string includes a plurality of parallel-connected electrodeless two-color flash cannons 21. In this embodiment, the LED lamp string only includes the electrodeless two-color flash cannons 21, and can be applied to application scenarios that only require the electrodeless two-color flash cannons 21.

[0062] Regarding the structural composition of the LED light group 1, in another possible implementation, the LED light group 1 includes forward and reverse lamp beads 31 and stepless two-color flash cannons 21 connected in parallel, wherein the number of forward and reverse lamp beads 31 and the number of stepless two-color flash cannons 21 are in a preset ratio. In this embodiment, the preset ratio can be determined according to actual needs, such as any ratio of 2:1, 3:1, 4:1, etc., and the embodiment of the utility model does not limit this. In this way, LED light strings with different structural compositions can be equipped according to the functional needs of the LED light string, making the lighting effects of the LED light string more diverse.

[0063] It can be seen from the above embodiments that since the LED light string includes a plurality of LED light groups 1 connected in series, and at least one of the plurality of LED light groups 1 includes at least one electrodeless two-color flash cannon 21 described in the first aspect, the LED light string at least has an electrodeless two-color flash cannon 21. In addition, since the electrodeless two-color flash cannon 21 uses only one built-in chip 211, it can achieve a multi-effect flashing effect, and does not need to be equipped with a voltage regulator tube, which reduces the production cost of the electrodeless two-color flash cannon 21 and improves production efficiency. Therefore, the production cost of the LED light string can be reduced, and the market competitiveness is correspondingly improved. In addition, in the embodiments of the utility model, the LED light string can be matched in any proportion, thereby making the application range of the LED light string wider.
