Technical Field

[0001] The utility model relates to the field of lighting, and in particular, to an LED lamp that expands color channels through multiple logic units. Background Art

[0002] Taking the LED lamp string with 8-bit color depth (referred to as 8-code lamp) on the market as an example, its LED lamp beads are RGB three-in-one lamp beads. Even if it includes 80 LED lamp beads, in the signal of this lamp string, 8-bit binary data is always used to control each color channel of all LED lamp beads.

[0003] However, users have a need to improve the visual effect of LED lamps. However, for some time, the physical color depth of any color channel of each LED lamp bead cannot be quickly increased.

[0004] Therefore, on the premise that the physical color depth of any color channel of LED lamp beads cannot be significantly broken through, it is urgent in this field to improve the visual effect of LED lamps in an innovative way. Summary of the Utility Model

[0021] m is 8 or 10.

[0022] Preferably,

[0023] The first hardware-based address encoding-decoder, according to a preset protocol and the address encoding of multiple LED beads in the first LED logic unit, parses out the signal for multiple LED beads in the first LED logic unit from the signals for all i light-emitting segments.

[0024] The second hardware-based address encoding-decoder, according to a preset protocol and the address encoding of multiple LED beads in the second LED logic unit, parses out the signal for multiple LED beads in the second LED logic unit from the signals.

[0025] Preferably,

[0026] All light-emitting segments are in a parallel or series relationship.

[0027] Preferably,

[0028] The LED lamp further includes an i-th light-emitting segment, where i ranges from 3 to N. Among them, the specifications of all the light-emitting segments of the LED lamp are the same.

[0029] The i-th light-emitting segment is connected to the i-th hardware-based address encoding-decoder, and the i-th hardware-based address encoding-decoder is used to encode the addresses of multiple LED beads in the i-th light-emitting segment, so that n LED beads in the i-th light-emitting segment form the i-th LED logic unit.

[0030] From the first LED logic unit to the Nth LED logic unit, all the logic units are cascaded in sequence front and back.

[0031] The LED lamp also synchronously controls each color channel of all the LED beads in the first LED logic unit to the Nth LED logic unit through the first hardware-based address encoding-decoder to the Nth hardware-based address encoding-decoder.

[0032] Preferably,

[0033] When m is 8, each color channel of each LED bead has an 8-bit color depth, and its brightness varies from 0 to 255.

[0034] And when N is 10, when the LED lamp synchronously controls each color channel of all the LED beads in the first LED logic unit to the tenth LED logic unit through the first hardware-based address encoding-decoder to the tenth hardware-based address encoding-decoder, each color channel is expanded to a total of N×m = 10×8, that is, 80-bit color depth.

[0035] Preferably,

[0036] The first hardware-based address encoding-decoder, according to a preset protocol and the address encoding of multiple LED beads in the first LED logic unit, parses out the signal for multiple LED beads in the first LED logic unit from the signals for all i light-emitting segments.

[0041] Preferred,

[0042] When any light segment is replaced with a new one due to a fault, the hardware-based address encoder-decoder corresponding to the light segment can re-encode the address of the LED lamp beads in the new light segment.

[0043] Preferred,

[0044] Except for the first hardware-based address encoder-decoder, any other hardware-based address encoder-decoder can encode the addresses of multiple LED lamp beads in the corresponding light-emitting segment by shifting in the form of a hardware shifter.

[0045] In summary, under the premise that the physical color depth of any color channel of the LED lamp beads cannot be significantly improved, the utility model logically divides any light-emitting segment with multiple LED lamp beads to obtain corresponding logical units, and then uses the combination of multiple logical units to achieve the equivalent color depth of each color channel or the expansion of the color channel in disguise. Since the surface area of ​​the current LED lamp beads is already very small, this expansion improves the visual effect of the LED lamp and makes it easier to achieve rich and delicate colors.

[0051] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will combine the drawings in the embodiments of the present utility model Figures 1 to 6 to clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. The components of the embodiments of the present utility model usually described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0052] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the protection scope of the present utility model.

[0053] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0054] In the description of the present utility model, it should be noted that if terms such as "upper", "lower", "inner", "outer", etc. are used to indicate the orientation or positional relationship, it is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the product of the present utility model is usually placed. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model.

[0055] In addition, if terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0056] It should be noted that, without conflict, the features in the embodiments of the present utility model can be combined with each other.

[0057] In one embodiment, the present utility model provides an LED lamp, and the LED lamp at least includes:

[0058] The first light segment and the second light segment,

[0059] The first light-emitting segment includes n LED lamp beads, where n is greater than or equal to 3,

[0060] The second light segment has the same specifications as the first light segment, and the second light segment also includes n LED lamp beads,

[0061] Among them,

[0062] The first light-emitting segment is connected to a first hardware-based address encoder-decoder, and the first hardware-based address encoder-decoder is used to encode the addresses of multiple LED lamp beads in the first light-emitting segment, so that n LED lamp beads in the first light-emitting segment constitute a first LED logic unit,

[0063] The second light-emitting segment is connected to a second hardware-based address encoder-decoder, and the second hardware-based address encoder-decoder is used to encode the addresses of the plurality of LED lamp beads in the second light-emitting segment, so that the n LED lamp beads in the second light-emitting segment constitute a second LED logic unit,

[0064] The first LED logic unit to the second LED logic unit forms a front-to-back cascade,

[0065] The LED lamp also expands and synchronously controls each color channel of all LED lamp beads in the first LED logic unit and the second LED logic unit through the combination of all LED logic units through the first hardware-based address encoder-decoder and the second hardware-based address encoder-decoder.

[0066] Therefore, under the premise that the physical color depth of any color channel of the LED lamp beads cannot be significantly improved, the utility model logically divides any light-emitting segment with multiple LED lamp beads to obtain corresponding logical units, and then uses the logical combination of multiple logical units to achieve the equivalence of the color depth of each color channel or the disguised expansion of the color channel. Since the surface area of ​​the current LED lamp beads is already very small, this expansion improves the visual effect of the LED lamp and makes it easier to achieve rich and delicate colors. It can be understood that the synchronous control process involves address decoding. After all, the utility model must meet the basic premise that each LED lamp bead works correctly. It should be noted that the address encoder-decoder is based on hardware, wherein the hardware encoding implementation method can be a relatively simple circuit such as a shifter or other circuits, and the corresponding decoding can also be implemented using a shifter or other circuits.

[0067] Most typically, the embodiments disclosed in the present invention are preferably applied to LED light strings, and any hardware-based address encoder-decoder and the corresponding light-emitting segment are integrated into one string. ​​​​​

[0068] In another embodiment,

[0069] Each LED lamp bead includes at least one color channel, which includes any one of the following or any combination thereof: red color channel R, green color channel G, blue color channel B, each color channel supports 2 to the mth power brightness control, where m represents the depth of each color channel.

[0070] Typical,

[0071] m is 8 or 10.

[0072] It can be understood that when m is 8, the depth of each color channel is 256, and the brightness can be adjusted from 0 to 255.

[0073] In another embodiment,

[0074] The LED lamp beads are RGB three-color LED lamp beads.

[0075] In another embodiment,

[0076] A first hardware-based address encoder-decoder, which parses the signals for the multiple LED lamp beads in the first LED logic unit from the signals for all i light-emitting segments according to a preset protocol and the address codes of the multiple LED lamp beads in the first LED logic unit,

[0077] The second hardware-based address encoder-decoder parses the signal for the multiple LED lamp beads in the second LED logic unit according to the preset protocol and the address encoding of the multiple LED lamp beads in the second LED logic unit.

[0078] For example, for ease of understanding, in one embodiment, it is assumed that: every 8 LED lamp beads are used as a logic unit, and it is assumed that a total of 2 logic units are involved. Then: although any color channel of each LED lamp bead still only adjusts the brightness of the color channel according to the 8-bit binary data it receives (i.e., 256-level brightness adjustment), the two logic units work together, and through synchronous control, the brightness of any color channel of each LED can be accurately controlled. The utility model can achieve richer and more delicate colors. Therefore, although this embodiment is still based on the original 256-level brightness adjustment of each LED lamp bead, this embodiment achieves the equivalent color depth of the color channel or the disguised expansion of the color channel through the synchronous control of multiple logic units.

[0079] In another embodiment,

[0080] Taking a string of LED lights as an example, the LED beads of this string of lights are, for example: WS2812 or other LED beads, which can perform data communication and control through a single-wire protocol (such as SPI or the proprietary OneWire protocol). It can be understood that the hardware-based address encoder-decoder realizes the control of the LED beads via the above-mentioned logic unit to achieve the expansion of the color channels in disguise, so as to achieve richer colors and animation effects.

[0081] Exemplarily, the hardware-based address encoder-decoder includes an integrated circuit (IC), and the integrated circuit is used to receive the input signal, and the signal carries the ID of the logic unit, the address of each bead, the brightness, and color information (such as RGB values).

[0082] Alternatively, in another example, the hardware-based address encoder-decoder may also include a microcontroller (MCU). Compared with the aforementioned integrated circuit (IC), it can be understood that the cost of the MCU is higher than that of the IC. If the hardware-based address encoder-decoder is implemented by the MCU, the microcontroller sends pulse width modulation (PWM) signals through specified pins, and these signals can also carry the ID of the logic unit, the address of each bead, the brightness, and color information.

[0083] It can be found that whether the hardware-based address encoder-decoder is implemented by the IC or the MCU, it actually generates the above signals through a predefined protocol and finally sends them to the LED beads, so that the LED beads can work properly.

[0084] In some potential advanced applications, if the display of the controlled LED beads is more complex, the amount of information in the signal is large and involves high-speed transmission, then, without considering the cost, other dedicated hardware codec chips may also be used in cooperation with the microcontroller MCU to process complex signal encoding and decoding to reduce the burden on the microcontroller and improve the overall system efficiency.

[0085] For the hardware-based address encoder-decoder,

[0086] Signals or data are usually transmitted in a serial manner and adopt a specific timing and encoding method (such as using 8-bit binary data for each color channel, and adding synchronization and error checking bits if necessary) to ensure accurate transmission and parsing. The hardware-based address encoder-decoder realizes the functions of address encoding and decoding for the logic unit and each lower-level LED bead. Each LED bead usually has its own integrated control IC, and after receiving the data of the LED bead, it adjusts the internal PWM signal according to the decoded information, thereby controlling the brightness and color of the LED.

[0087] Regarding the timing generation and signal shaping in the communication or transmission process, it can be understood that in order to ensure the correct transmission of data, the sending end needs to precisely control the pulse width and interval of the signal, which can be achieved through the timing generation and signal shaping circuit. This part can refer to the existing technology to ensure the accurate reading of data and avoid signal distortion.

[0088] In another embodiment,

[0089] All the light-emitting segments are in a parallel or series relationship.

[0090] Exemplarily, refer to Figure 1 and Figure 2 , where c1 and c2 respectively represent the first and second hardware-based address encoding-decoders, s1 and s2 respectively represent the first and second light-emitting segments. The figure also shows the + and - power supply lines and the DIN signal line. Among them,

[0091] i) Refer to Figure 1 , when in a parallel relationship, not only the two power supply lines (for example, the positive line and the negative line) are connected to all the light-emitting segments in a bus manner, but also the signal lines of all the hardware-based address encoding-decoders are the same signal line. At this time, any hardware-based address encoding-decoder resolves the signals of multiple LED beads in the LED logic unit corresponding to this hardware-based address encoding-decoder from the signals for all the light-emitting segments;

[0092] ii) Refer to Figure 2 , when in a series relationship, not only the two power supply lines (for example, the positive line and the negative line) are connected to all the light-emitting segments in series in sequence, but also the signal lines of all the hardware-based address encoding-decoders are in series. At this time, starting from the second hardware-based address encoding-decoder, each hardware-based address encoding-decoder resolves the signals of multiple LED beads in the LED logic unit corresponding to this hardware-based address encoding-decoder from the signals output by the previous hardware-based address encoding-decoder.

[0093] In another embodiment,

[0094] The LED lamp further includes the i-th light-emitting segment, where i ranges from 3 to N. Among them, all the light-emitting segments of the LED lamp have the same specifications.

[0095] The i-th light-emitting segment is connected to the i-th hardware-based address encoding-decoder, and the i-th hardware-based address encoding-decoder is used to encode the addresses of multiple LED beads in the i-th light-emitting segment, so that n LED beads in the i-th light-emitting segment form the i-th LED logic unit.

[0096] From the first LED logic unit to the Nth LED logic unit, all the logic units are cascaded in sequence front and back.

[0097] The LED lamp also synchronously controls each color channel of all the LED beads in the first LED logic unit to the Nth LED logic unit through the first hardware-based address encoder-decoder to the Nth hardware-based address encoder-decoder.

[0098] In another embodiment,

[0099] When m is 8, each color channel of each LED bead has an 8-bit color depth, and its brightness varies from 0 to 255.

[0100] And when N is 10, when the LED lamp synchronously controls each color channel of all the LED beads in the first LED logic unit to the tenth LED logic unit through the first hardware-based address encoder-decoder to the tenth hardware-based address encoder-decoder, each color channel is expanded to a total of N×m = 10×8, that is, 80-bit color depth.

[0101] For a product with 80 LED beads in the prior art, in the signal of this lamp, 8-bit binary data is always used to control each color channel of all the LED beads. In contrast, this embodiment can expand each color channel to a total of 80-bit color depth, so that 80-bit binary data can be used to control the LED lamp, achieving a replacement visual effect.

[0102] In another embodiment,

[0103] The first hardware-based address encoder-decoder, according to a preset protocol and the address encoding of multiple LED beads in the first LED logic unit, parses out the signal for multiple LED beads in the first LED logic unit from the signal for all i light-emitting segments.

[0104] The second hardware-based address encoder-decoder, according to a preset protocol and the address encoding of multiple LED beads in the second LED logic unit, parses out the signal for multiple LED beads in the second LED logic unit from the signal.

[0105] The ith hardware-based address encoder-decoder, according to a preset protocol and the address encoding of multiple LED beads in the ith LED logic unit, parses out the signal for multiple LED beads in the ith LED logic unit from the signal.

[0106] In this way, until the Nth hardware-based address encoder-decoder, which parses, according to a preset protocol and the address encoding of multiple LED beads in the Nth LED logic unit, the signal for the multiple LED beads in the Nth LED logic unit from the signal,

[0107] so that the LED lights can synchronously control each color channel of all the LED beads in the first LED logic unit to the Nth LED logic unit through the first hardware-based address encoder-decoder to the Nth hardware-based address encoder-decoder.

[0108] Thus, this embodiment can create impressive visual effects, such as smoother color transitions, more dynamic light and shadow flows, etc., by synchronously controlling multiple LED beads in each logic unit of multiple logic units, and realizes a creative application of the existing color control ability.

[0109] In another embodiment,

[0110] When any light-emitting segment is replaced with a new one due to a fault, the corresponding hardware-based address encoder-decoder of the light-emitting segment can re-encode the addresses of the LED beads in the new light-emitting segment.

[0111] It can be understood that this embodiment means that any hardware-based address encoder-decoder is also used to maintain the faulty light-emitting segment it is connected to. In practice, LED beads are more likely to fail than hardware-based address encoder-decoders. Therefore, in most cases, the hardware-based address encoder-decoder is still in good working condition. Then, when the light-emitting segment is replaced with a new one due to a fault, power is supplied to the hardware-based address encoder-decoder and the new light-emitting segment, and the signal line between the hardware-based address encoder-decoder and the new light-emitting segment is connected, so that the hardware-based address encoder-decoder can re-encode the addresses of the LED beads in the new light-emitting segment, so that the entire LED light can still work normally.

[0112] In another embodiment,

[0113] For any two light-emitting segments, the initial address encodings of the corresponding LED beads are exactly the same.

[0114] The most important positive impact of this embodiment is that when each light-emitting segment is an LED light string component, the addresses of each LED light string component can be made the same. If a certain light-emitting segment needs to be replaced due to maintenance, then it can be encoded by the corresponding hardware-based address encoder-decoder connected to the light-emitting segment.

[0115] In one embodiment,

[0116] The hardware-based address encoder-decoder further includes a memory that stores the address information of the hardware-based address encoder-decoder.

[0117] Exemplarily, when the first light-emitting segment and the second light-emitting segment are independently produced, the addresses of their respective 8 LED beads are all 1-8. Then, when the above two light-emitting segments and the corresponding hardware-based address encoder-decoder form an LED lamp, such as an LED lamp string, since the memory of the hardware-based address encoder-decoder connected to the second light-emitting segment stores the address information of 07, the address of the second light-emitting segment can continue to be re-encoded downward from the address of the last 1 LED bead of the first light-emitting segment, becoming 9-16, and so on.

[0118] Therefore, in another embodiment,

[0119] Except for the first hardware-based address encoder-decoder, any other hardware-based address encoder-decoder can encode the addresses of multiple LED beads in the corresponding light-emitting segment by shifting in the manner of a hardware shifter.

[0120] In one embodiment,

[0121] The address information of the hardware-based address encoder-decoder is preset. For example, the aforementioned 07. It can be understood that 07 indicates that the hardware-based address encoder-decoder targets 8 LED beads. If 10 LED beads are needed, the address of the hardware-based address encoder-decoder is 09.

[0122] Furthermore, in one embodiment,

[0123] The hardware-based address encoder-decoder can re-set the address information of the hardware-based address encoder-decoder by obtaining the signal input from the previous stage.

[0124] Typically, when the first light-emitting segment and the second light-emitting segment are connected in series, then, assuming that the current hardware-based address encoder-decoder is connected to the second light-emitting segment, the signal input of the previous stage can come from the last LED lamp bead of the first light-emitting segment. As mentioned above, the address of the last LED lamp bead of the previous stage is 8. Therefore, after obtaining this address, the current hardware-based address encoder-decoder can reset the address of the hardware-based address encoder-decoder, and encode the address of the first LED lamp bead of the second light-emitting segment according to the reset address of the hardware-based address encoder-decoder, thereby further realizing the recoding of the addresses of all LED lamp beads of the second light-emitting segment. In fact, in the series mode, for multiple LED lamp beads in the current LED logic unit, after the last LED lamp bead has processed its own light according to the signal input, the hardware-based address encoder-decoder corresponding to the current LED logic unit can transmit signals to the hardware-based address encoder-decoder of the subsequent LED logic unit, thereby providing new signal outputs to the LED lamp beads in the subsequent LED logic unit. This signal output can enable the LED lamp beads in the subsequent LED logic unit to accurately identify the incoming signals and enable the subsequent remaining LED lamp beads to work normally.

[0125] In another embodiment,

[0126] For the signal line between the hardware-based address encoder-decoder and each LED lamp bead in the corresponding light-emitting segment, the corresponding relationship between the signal transmitted on the signal line and the address of the LED lamp bead can be known. The hardware-based address encoder-decoder can also not re-encode the address code of the LED lamp bead, but encode the signal on the signal line so that it can correctly correspond to the corresponding LED lamp bead.

[0127] It can be understood that these are two encoding methods that can be flexibly selected based on the correspondence between the two. No matter which method is used, it is to encode the signal related to the address, and does not involve other data signals in a narrow sense of how the LED lamp beads emit light. Because no matter what is done, it is to drive the LED lamp beads to work properly. The utility model does not involve changes to the data signal in a narrow sense at this time. It is for this reason that the preset protocol described in the utility model, that is, the communication protocol between the LED lamp beads and the signals they receive, has no specific regulations. As long as the correspondence between the signal transmitted on the signal line and the address of the LED lamp beads is met, the address and data signals can be correctly parsed.

[0128] Further, the LED lights do not necessarily need to uniformly assign all address codes to all the light-emitting segments according to a certain rule at one time before leaving the factory. The address coding can be completely implemented during on-site use. Since the address can be re-coded through a hardware-based address coding-decoder, the present utility model helps to re-code in the case of a failure of a certain light-emitting segment. For example:

[0129] It only needs to remove the faulty light-emitting segment, and then use the hardware-based address coding-decoder to re-code the addresses of the LED lamp beads in the replaced light-emitting segment;

[0130] Especially when implemented in a shifted manner, as mentioned in the previous embodiment, since each hardware-based address coding-decoder has its own address information. For example, the address information stored in the aforementioned hardware-based address coding-decoder is 07. Then, when re-coding, the hardware-based address coding-decoder naturally knows how many LED lamp beads are divided into a logical unit. As mentioned before, when the first light-emitting segment and the second light-emitting segment are independently produced, the addresses of the 8 LED lamp beads in each of them are 1-8. Then, when the above two light-emitting segments and the corresponding hardware-based address coding-decoder form an LED light, such as an LED lamp string, since the address information stored in the memory of the hardware-based address coding-decoder connected to the second light-emitting segment is 07, the address of the second light-emitting segment can then continue to re-code downward from the address of the last LED lamp bead of the first light-emitting segment and become 9-16, and so on.

[0131] In another embodiment,

[0132] The hardware-based address coding-decoder has 3 terminals, and the 3 terminals are of an integrated design and are plug-in type to facilitate the connection of the hardware-based address coding-decoder to the previous stage, the subsequent stage, and the current light-emitting segment.

[0133] It can be understood that such a plug-in design is beneficial to the assembly and subsequent maintenance of LED lamp products.

[0134] In another embodiment,

[0135] The hardware-based address coding-decoder is used for LED lights with different voltage levels such as 4.5V, 5V, 12V, or 36V.
