Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of LED light sources, and in particular to an LED light-emitting device and a COB light source. Background Art
[0002] With the development of the LED lighting industry, competition between branded and offline electric light source components is becoming increasingly fierce, leading to the emergence of counterfeit and inferior products, as well as counterfeit and parallel import products, which disrupt the market. To enhance anti-counterfeiting capabilities, radio frequency identification (RFID) technology is commonly used. Existing RFID technology embeds RFID chips into LED light sources, encoding key information such as production date, serial number, and shipping region. During market inspections, specialized reader / writers can read this information to identify genuine products and verify whether they are counterfeit or parallel import products.
[0003] However, since the LED light source is a passive device, the RFID chip and the LED are set separately, that is, the RFID chip and the LED light source are independent of each other. After the RFID chip is destroyed and removed, the LED light source can continue to be used normally, making this type of anti-counterfeiting technology easy to crack, and thus making it impossible to trace the light source through the RFID chip. Utility Model Content
[0004] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide an LED lighting device and a COB light source that effectively improve traceability reliability.
[0005] The purpose of this disclosure is achieved through the following technical solutions:

[0025] See also Figure 1, which is a structural diagram of an LED light-emitting device according to an embodiment of the present disclosure.
[0026] An LED lighting device 10 of an embodiment includes a light board 100 and a light-emitting anti-counterfeiting component 200; the light board 100 has an anti-counterfeiting packaging area 102; please refer to Figure 2 The light-emitting anti-counterfeiting component 200 includes an LED light-emitting component 210, a radio frequency memory 220 and a package 230. The LED light-emitting component 210 and the radio frequency memory 220 are both arranged in the anti-counterfeiting package area 102. The input end of the LED light-emitting component 210 is used to connect to the positive pole of the power supply, the output end of the radio frequency memory 220 is connected to the positive power supply of the radio frequency memory 220, and the negative power supply of the radio frequency memory 220 is used to connect to the negative pole of the power supply. The package 230 is respectively connected to the LED light-emitting component 210, the radio frequency memory 220 and the light board 100, and the package 230 covers the LED light-emitting component 210 and the radio frequency memory 220.
[0027] In this embodiment, the package 230 simultaneously encapsulates the RF memory 220 and the LED light-emitting component 210 in the anti-counterfeiting packaging area 102. If the RF memory 220 is to be removed, the package 230 needs to be removed. In the process of removing the package 230, since the package 230 is connected to the LED light-emitting component 210, the LED light-emitting component 210 will be removed together, making the LED light-emitting component 210 unable to work normally, thereby avoiding damage to the RF memory 220 and effectively improving the traceability reliability of the LED light-emitting component 210.
[0028] In one embodiment, see Figure 1, the projection of the package 230 on the lamp board 100 is located in the anti-counterfeiting package area 102. In this embodiment, the anti-counterfeiting package area 102 corresponds to the LED light-emitting component 210 and the radio frequency memory 220. Specifically, the LED light-emitting component 210 and the radio frequency memory 220 are both welded to the circuit in the anti-counterfeiting package area 102. The LED light-emitting component 210 serves as a light source to provide output light. The radio frequency memory 220 serves as a traceability anti-counterfeiting reading chip. Specifically, the radio frequency memory 220 is an RFID chip, which is used to store key information such as the production time, production serial number, and shipping area of the current LED light-emitting device. The anti-counterfeiting packaging area 102 is also provided with at least a portion of the packaging member 230, and the projection area of the packaging member 230 on the light board 100 corresponds to the anti-counterfeiting packaging area 102, so that the packaging member 230 can simultaneously fix the LED light-emitting component 210 and the RF memory 220 on the light board 100, thereby realizing the joint packaging of the LED light-emitting component 210 and the RF memory 220.
[0029] In one embodiment, the projected area of the package 230 on the light board 100 is greater than or equal to the area of the anti-counterfeiting packaging area 102. In this embodiment, the projected area of the package 230 on the light board 100 is in a size relationship with the area of the anti-counterfeiting packaging area 102. The projected area of the package 230 on the light board 100 is greater than or equal to the area of the anti-counterfeiting packaging area 102, indicating that the package 230 can completely cover the anti-counterfeiting packaging area 102, ensuring that all components in the anti-counterfeiting packaging area 102 can be encapsulated on the light board 100 by the package 230, so that the LED light-emitting element 210 and the RF memory 220 are synchronously encapsulated between the light board 100 and the package 230.
[0030] In one embodiment, see Figure 1The light-emitting anti-counterfeiting component 200 further includes a light source dam ring 240, which is provided on the light board 100 so that the middle portion of the light source dam ring 240 corresponds to the anti-counterfeiting packaging area 102. In this embodiment, the light source dam ring 240 is connected to the light board 100, and the inner area of the light source dam ring 240 coincides with the anti-counterfeiting packaging area 102. Specifically, the inner wall of the light source dam ring 240 is aligned with the edge of the anti-counterfeiting packaging area 102. The light source dam ring 240 serves as a packaging limiter within the anti-counterfeiting packaging area 102, that is, the inner space of the light source dam ring 240 is used to accommodate the package 230, so as to facilitate confining the package 230 within the anti-counterfeiting packaging area 102, so as to ensure that the package 230 stably packages the LED light-emitting component 210 and the radio frequency memory 220 on the light board 100.
[0031] Furthermore, the inner wall of the light source dam ring 240 is bonded to the packaging member 230. In this embodiment, the inner wall of the light source dam ring 240 is fixed to the light board 100 through the packaging member 230. Specifically, the packaging member 230 is a transparent or translucent strong glue. The light source dam ring 240 and the packaging member 230 are bonded to each other, which facilitates the fixed installation of the light source dam ring 240.
[0032] In another embodiment, the package 230 is an epoxy resin package.
[0033] Furthermore, the height of the light source dam ring 240 is greater than or equal to the height of the package 230. In this embodiment, the interior of the light source dam ring 240 corresponds to the anti-counterfeiting package area 102. The package 230 is disposed within the light source dam ring 240. The package 230 encapsulates the LED light-emitting element 210 and the RF memory 220 within the light source dam ring 240. The height of the light source dam ring 240 is greater than or equal to the height of the package 230, indicating that the distance the light source dam ring 240 protrudes from the light board 100 is higher than or equal to the distance the package 230 protrudes from the light board 100, thereby preventing the package 230 from overflowing from the light source dam ring 240.
[0034] In one embodiment, see Figure 1The luminous anti-counterfeiting component 200 further includes a radio frequency antenna 250, which is disposed on the light board 100 and is connected to the reading sensing end of the radio frequency memory 220. In this embodiment, the radio frequency antenna 250 serves as an external sensing antenna for the radio frequency memory 220. Through the mutual induction between the radio frequency antenna 250 and the card reader, the key information stored in the radio frequency memory 220 can be read.
[0035] In another embodiment, at least a portion of the RF antenna 250 is located in the anti-counterfeiting packaging area 102 , and the packaging component 230 covers at least a portion of the RF antenna 250 , so as to package and fix the RF antenna 250 on the light board 100 .
[0036] Furthermore, the light board 100 is provided with an antenna accommodating groove 104, and the RF antenna 250 is clamped in the antenna accommodating groove 104. In this embodiment, the antenna accommodating groove 104 is located on the light board 100. Specifically, the antenna accommodating groove 104 is provided around the anti-counterfeiting packaging area 102. The RF antenna 250 is accommodated in the antenna accommodating groove 104, so that the RF antenna 250 is stably fixed on the light board 100. Moreover, the antenna accommodating groove 104 is in communication with the anti-counterfeiting packaging area 102, facilitating the connection between the RF antenna 250 and the RF memory 220 in the anti-counterfeiting packaging area 102.
[0037] In one embodiment, see Figure 1 The LED light-emitting device 10 also includes an electrode sheet 300 arranged on the lamp board 100, and the electrode sheet 300 includes a positive electrode sheet 310 and a negative electrode sheet 320. The positive electrode sheet 310 is electrically connected to the input end of the LED light-emitting component 210, and the negative electrode sheet 320 is electrically connected to the negative power supply electrode of the radio frequency memory 220. In this embodiment, the positive electrode sheet 310 and the negative electrode sheet 320 are used to connect to the positive and negative electrodes of the power supply, that is, power is supplied to the LED light-emitting element 210 and the RF memory 220 through the positive electrode sheet 310 and the negative electrode sheet 320. Moreover, the LED light-emitting element 210 and the RF memory 220 are connected in series, so that a series power supply circuit is formed between the LED light-emitting element 210, the RF memory 220, and the power supply. This ensures that after the RF memory 220 is damaged and fails, the power supply circuit is disconnected, thereby causing the LED light-emitting element 210 to stop working, thereby avoiding the situation where the LED light-emitting element 210 continues to emit light normally after the RF memory 220 is removed.
[0038] In another embodiment, the LED light-emitting element includes a plurality of LED light source crystals connected in series.
[0039] In one embodiment, the present disclosure also relates to a COB light source, comprising the LED light-emitting device described in any of the above embodiments. In this embodiment, the LED light-emitting device comprises a lamp board and a light-emitting anti-counterfeiting component; the lamp board has an anti-counterfeiting packaging area; the light-emitting anti-counterfeiting component comprises an LED light-emitting element, a radio frequency memory and a packaging element, the LED light-emitting element and the radio frequency memory are both arranged in the anti-counterfeiting packaging area, the input end of the LED light-emitting element is used to connect to the positive pole of the power supply, the output end of the radio frequency memory is connected to the positive power supply of the radio frequency memory, the negative power supply of the radio frequency memory is used to connect to the negative pole of the power supply, the packaging element is respectively connected to the LED light-emitting element, the radio frequency memory and the lamp board, and the packaging element covers the LED light-emitting element and the radio frequency memory. The package simultaneously encapsulates the RF memory and the LED light-emitting component in the anti-counterfeiting packaging area. If the RF memory is to be removed, the package needs to be removed. In the process of removing the package, since the package is connected to the LED light-emitting component, the LED light-emitting component will be removed together, making the LED light-emitting component unable to work normally, thereby avoiding damage to the RF memory and effectively improving the traceability reliability of the LED light-emitting component.
[0040] The above-described embodiments merely represent several implementation methods of the present disclosure.
