Description

Technical Field

[0001] The present disclosure relates to the technical field of LED lights, and particularly to an LED light source circuit and an LED light source. Background Technique

[0002] Currently, with the development of the LED lighting industry, the competition between brand light source devices and circulating light source devices is becoming increasingly fierce, and there have emerged phenomena such as counterfeit and shoddy products and cross-region sales that disrupt the market. In order to improve the anti-counterfeiting level, radio frequency identification technology is usually adopted. In the existing radio frequency identification technology, an RFID chip is implanted into the LED light source, and key information such as production time, production serial number, and shipping area is written into the RFID chip. During market inspection, a dedicated reading and writing device is used to read the relevant information, which can identify whether it is a genuine product and whether there is cross-region sales.

[0003] However, since the LED light source is a passive device, the RFID chip and the LED are separately arranged, that is, the RFID chip circuit and the LED light source circuit are independent of each other. Often during cross-region sales, only by removing the RFID chip, the LED light source can still be used, which leads to such anti-counterfeiting technology being easily cracked and unable to trace the source. Summary of the Utility Model

[0004] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide an LED light source circuit and a COB light source that can effectively avoid cross-region sales.

[0005] The purpose of the present disclosure is achieved through the following technical solutions:

The output end of the LED light source group is connected to the first power supply end of the radio frequency anti-counterfeiting memory, and the second power supply end of the radio frequency anti-counterfeiting memory is used to connect to the negative pole of the LED power supply; the sampling output end of the radio frequency anti-counterfeiting memory is connected to the radio frequency antenna, and the radio frequency anti-counterfeiting memory is used to store LED light source traceability anti-counterfeiting information.

[0007] In one embodiment, the LED light source group includes a plurality of first LED lights connected in series.

[0008] In one embodiment, the number of the first LED lights is 10 to 14.

[0009] In one embodiment, the number of the first LED lights is 12.

[0010] In one embodiment, the LED light source group further includes a plurality of second LED lights connected in series, and the plurality of second LED lights connected in series are connected in parallel with the plurality of first LED lights connected in series.

[0011] In one embodiment, the number of the second LED lights is 10 to 14.

[0012] In one embodiment, the number of the second LED lights is equal to the number of the first LED lights.

[0013] In one embodiment, the first LED light and the second LED light are RGB-LED lights.

[0014] In one embodiment, the radio frequency anti-counterfeiting circuit further includes a current-limiting resistor, and an output end of the LED light source group is connected to a first power supply end of the radio frequency anti-counterfeiting memory through the current-limiting resistor.

[0015] A COB light source includes the LED light source circuit according to any one of the above embodiments.

[0016] Compared with the prior art, the present disclosure has at least the following advantages:

[0017] After the radio frequency anti-counterfeiting memory is removed, since the LED light source group is connected in series with the radio frequency anti-counterfeiting memory, the current output by the LED power supply is interrupted after passing through the LED light source group and cannot form a power supply loop, so that the LED light source group loses power, and thus the LED light source group cannot work and emit light normally, avoiding the continuous use of the LED light source, and effectively avoiding the occurrence of cross-selling.

[0020] To facilitate understanding of the present disclosure, the present disclosure will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present disclosure are shown in the drawings. However, the present disclosure can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure content of the present disclosure more thorough and comprehensive.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this disclosure belongs. The terms used in the specification of this disclosure herein are only for the purpose of describing specific implementations and are not intended to limit this disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0023] This disclosure relates to an LED light source circuit. In one embodiment, the LED light source circuit includes an LED light source group and a radio frequency anti-counterfeiting circuit; the input end of the LED light source group is used to connect to the positive pole of the LED power supply; the radio frequency anti-counterfeiting circuit includes a radio frequency anti-counterfeiting memory and a radio frequency antenna, the output end of the LED light source group is connected to the first power supply end of the radio frequency anti-counterfeiting memory, and the second power supply end of the radio frequency anti-counterfeiting memory is used to connect to the negative pole of the LED power supply; the sampling output end of the radio frequency anti-counterfeiting memory is connected to the radio frequency antenna, and the radio frequency anti-counterfeiting memory is used to store LED light source traceability anti-counterfeiting information. After the radio frequency anti-counterfeiting memory is removed, since the LED light source group is in series with the radio frequency anti-counterfeiting memory, the current output by the LED power supply is interrupted after passing through the LED light source group and cannot form a power supply loop, causing the LED light source group to lose power, so that the LED light source group cannot work normally and emit light, avoiding the continuous use of the LED light source, and thus effectively avoiding the occurrence of cross-selling.

[0024] Please refer to Figure 1 , which is a schematic structural diagram of the LED light source circuit according to an embodiment of this disclosure.

[0025] The LED light source circuit 10 of an embodiment includes an LED light source group 100 and a radio frequency anti-counterfeiting circuit 200. The input end of the LED light source group 100 is used to connect to the positive pole of the LED power supply. The radio frequency anti-counterfeiting circuit 200 includes a radio frequency anti-counterfeiting memory U1 and a radio frequency antenna RFL1. The output end of the LED light source group 100 is connected to the first power supply end of the radio frequency anti-counterfeiting memory U1, and the second power supply end of the radio frequency anti-counterfeiting memory U1 is used to connect to the negative pole of the LED power supply. The sampling output end of the radio frequency anti-counterfeiting memory U1 is connected to the radio frequency antenna RFL1, and the radio frequency anti-counterfeiting memory U1 is used to store LED light source traceability anti-counterfeiting information.

[0026] In this embodiment, after the radio frequency anti-counterfeiting memory U1 is removed, since the LED light source group 100 is in series with the radio frequency anti-counterfeiting memory U1, the current output by the LED power supply is interrupted after passing through the LED light source group 100, and a power supply loop cannot be formed, causing the LED light source group 100 to lose power, so that the LED light source group 100 cannot work normally and emit light, avoiding the continued use of the LED light source, and effectively avoiding the occurrence of cross-selling.

[0027] In one of the embodiments, please refer to Figure 1 , the LED light source group 100 includes a plurality of first LED lights D1 connected in series. In this embodiment, the first LED light D1 serves as the light-emitting source of the LED light source group 100 for outputting light. A plurality of the first LED lights D1 are connected in series in sequence. Specifically, a plurality of the first LED lights D1 are connected end to end in a straight line. The positive pole of the first LED light D1 at the head end is connected to the positive pole of the LED power supply, and the negative pole of the first LED light D1 at the head end is connected to the positive pole of the next first LED light D1, and so on, until the negative pole of the first LED light D1 at the end is connected to the negative pole of the LED power supply.

[0028] Furthermore, the number of the first LED lights D1 is 10 to 14. In this embodiment, the distances between the first LED lights D1 are evenly distributed, which is convenient for forming a uniformly distributed planar light-emitting surface.

[0029] In another embodiment, the number of the first LED lights D1 is 12.

[0030] In one of the embodiments, please refer to Figure 1, the LED light source group 100 further includes a plurality of second LED lights D2 connected in series, and the plurality of second LED lights D2 connected in series are connected in parallel with the plurality of first LED lights D1 connected in series. In this embodiment, the second LED lights D2 serve as the second set of light-emitting sources of the LED light source group 100 for enhancing the output light. The plurality of second LED lights D2 are connected in series in sequence. Specifically, the plurality of second LED lights D2 are connected end to end in a straight line. The positive electrode of the second LED light D2 at the head end is connected to the positive electrode of the LED power supply, and the negative electrode of the second LED light D2 at the head end is connected to the positive electrode of the next second LED light D2, and so on until the negative electrode of the second LED light D2 at the tail end is connected to the negative electrode of the LED power supply. The lamp string formed by the plurality of second LED lights D2 is connected in parallel with the lamp string formed by the plurality of first LED lights D1, that is, the positive electrode of the second LED light D2 at the head end is connected to the positive electrode of the first LED light D1 at the head end, and moreover, the negative electrode of the second LED light D2 at the tail end is connected to the negative electrode of the first LED light D1 at the tail end, so that the voltage drop of the second LED is the same as that of the first LED light D1, thereby making the light emission intensity of the second LED equal to that of the first LED light D1.

[0031] In another embodiment, each of the second LEDs is connected in parallel with a first LED light D1.

[0032] In another embodiment, the number of the second LED lights D2 is 10 to 14. The spacing between the second LED lights D2 is evenly distributed, and together with the plurality of first LED lights D1, a uniformly distributed planar light-emitting surface is formed.

[0033] In another embodiment, the number of the second LED lights D2 is equal to the number of the first LED lights D1, so that the light emission is more uniform.

[0034] In another embodiment, the first LED light D1 and the second LED light D2 are RGB-LED lights, which is convenient for generating different combined color lights.

[0035] In one of the embodiments, the radio frequency anti-counterfeiting circuit further includes a current-limiting resistor, and the output end of the LED light source group is connected to the first power supply end of the radio frequency anti-counterfeiting memory through the current-limiting resistor. In this embodiment, one end of the current-limiting resistor is connected to the output end of the LED light source group, and the other end of the current-limiting resistor is connected to the first power supply end of the radio frequency anti-counterfeiting memory. Specifically, the current-limiting resistor is connected in series between the LED light source group and the radio frequency anti-counterfeiting memory. The current-limiting resistor limits the current flowing into the power supply end of the radio frequency anti-counterfeiting memory to avoid the situation that the supply current of the radio frequency anti-counterfeiting memory is too large, ensuring the normal operation of the radio frequency anti-counterfeiting memory.

[0036] In one of the embodiments, the present disclosure also relates to a COB light source, including the LED light source circuit described in any of the above embodiments. In this embodiment, the LED light source circuit includes an LED light source group and a radio frequency anti-counterfeiting circuit; the input end of the LED light source group is used to connect to the positive pole of the LED power supply; the radio frequency anti-counterfeiting circuit includes a radio frequency anti-counterfeiting memory and a radio frequency antenna. The output end of the LED light source group is connected to the first power supply end of the radio frequency anti-counterfeiting memory, and the second power supply end of the radio frequency anti-counterfeiting memory is used to connect to the negative pole of the LED power supply; the sampling output end of the radio frequency anti-counterfeiting memory is connected to the radio frequency antenna, and the radio frequency anti-counterfeiting memory is used to store the LED light source traceability anti-counterfeiting information. After the radio frequency anti-counterfeiting memory is removed, since the LED light source group is in series with the radio frequency anti-counterfeiting memory, the current output by the LED power supply is interrupted after passing through the LED light source group and cannot form a power supply loop, causing the LED light source group to lose power, so that the LED light source group cannot work and emit light normally, avoiding the continued use of the LED light source for emitting light, and thus effectively avoiding the occurrence of cross-selling situations.

[0037] The above-described embodiments only represent several implementation manners of the present disclosure, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the present disclosure patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
