[0001] The present invention relates to a light-control instruction extension device and an associated instruc- tion set. BACKGROUND

[0002] With the development of electronic products featuring lighting effects (for example, gaming devices or devices with decorative lighting), the demand for more diverse light-control effects and an increased number of controllable lighting elements has gradually risen. How- ever, devices equipped with lighting control functions, such as computers, have inherent limitations on the number of controlled lighting elements. Accordingly, when, for example, a lighting strip including a relatively large number of serially connected light-emitting ele- ments is incorporated into an electronic device, a light- ing-control interface of the electronic device may be unable to control all of the light-emitting elements. This may result in abnormal lighting effects, such as certain light-emitting elements failing to emit light properly.

[0003] In viewof theabove, it is evident that theprior art still suffers from problems such as insufficient or incom- plete light-control instructions, which require improve- ment and resolution. SUMMARY

[0004] Accordingly, the present invention provides a light-control instruction extension device and an instruc- tion set, so as to effectively resolve various problems encountered in the prior art.

[0005] One objective of the present invention is to provide a device and an instruction set capable of ex- tending insufficient light-control instructions.

[0006] In an embodiment of the present invention, a light-control instruction extensiondevice is provided. The light-control instruction extension device includes an in- put interface, a processing unit, and an output interface. The input interface is configured to receive a light-control instruction from a light-control instruction source. The processing unit is configured to receive the light-control instruction and to output an extended light-control in- struction. The light-control instruction corresponds to a first number of light-emitting elements, and the extended light-control instruction corresponds to a second number of light-emitting elements, wherein the first number is smaller than the second number. The output interface is configured to output the extended light-control instruc- tion.

[0007] In an embodiment, the processing unit repeats at least a portion of the light-control instruction to gen- erate the extended light-control instruction.

[0008] In an embodiment, the number of repetitions of the at least a portion of the light-control instruction per- formed by the processing unit is equal to a quotient obtained by dividing the second number by the first number.

[0009] In an embodiment, the processing unit further receives an adjustment command, wherein the adjust- ment command indicates the number of repetitions of the at least a portion of the light-control instruction.

[0010] In an embodiment, the input interface is an ARGB interface.

[0011] In an embodiment, the light-control instruction source is a motherboard.

[0012] In an embodiment, the light-emitting element is a single-wire RGB light-emitting diode (LED).

[0013] Inanotherembodimentof thepresent invention, an instruction set for extending a light-control instruction is provided. The instruction set is stored in a storage medium. When a processing unit reads the instruction set from the storage medium, the instruction set causes the processing unit to: read the light-control instruction; and repeat outputting at least a portion of the light-control instruction according to a repetition count.

[0014] In an embodiment, the light-control instruction corresponds to a first number of light-emitting elements, and the repetition count is an integer multiple of the first number.

[0015] In an embodiment, the instruction set further causes the processing unit to read an adjustment com- mand indicating the repetition count.

[0016] In summary, through the light-control instruction extension device and the instruction set of the present invention, a light-control instruction provided by a light- control instruction source may be extended, thereby extending a light-control instruction originally corre- sponding to a first number of light-emitting elements into a command capable of controlling a second number of light-emitting elements.

[0020] In the present invention, the terms "exemplary" and "for example" are intended to mean "serving as an example, instance, or illustration." Any embodiment or aspect described as "exemplary" or "for example" should not necessarily be interpreted as being preferred or advantageous over other aspects of the invention.

[0021] In an embodiment of the present invention, a light-control instruction extension device is provided. Referring to FIG. 1, FIG. 1 illustrates a light-control in- struction extension device 100 including an input inter- face 110, a processing unit 120, and an output interface 130. The input interface 110 is configured to receive a light-control instruction (CI) from a light-control instruc- tion source. The processing unit 120 is configured to receive the light-control instruction (CI) and output an extended light-control instruction (ECI) to a light-emitting element group.

[0022] In an embodiment, the light-control instruction source is, for example, a computer motherboard, or a circuit or device formed by a control chip (e.g., MCU, ASIC, or FPGA) for single-wire RGB light-emitting diodes. In an embodiment, the light-control instruction source is configured to output the light-control instruction (CI) to the input interface 110 of the light-control instruc- tion extension device 100 through data transmission protocols such as GPIO, SPI, or 12C. In an embodiment, the input interface 110 of the light-control instruction extension device 100 can be configured by any interface corresponding to the light-control instruction source. For example, the input interface 110 and / or the output inter- face 130 of the light-control instruction extension device 100 is an ARGB interface. In the embodiment, the ARGB interface is commonlyemployed for controlling light-emit- ting elements and helps reduce interface conversion complexity. Therefore, the ARGB interface is compatible with a greater number of existing lighting devices.

[0023] In an embodiment, the light-control instruction (CI) includes, for example, a data signal and a latch signal. Specifically, the data signal is configured to re- present red (R), green (G), or blue (B) for each light- emittingelementbybit signal(s) (e.g., 8bits).On theother hand, the latch signal is configured to latch the status of each light-emitting element. Once the light-emitting ele- ment receives the latch signal, the light-emitting element updates the status according to a corresponding data signal.

[0024] In an embodiment, a first light-emitting element group 300 is formed by cascaded single-wireRGBLEDs. Specifically, the light-emitting elements may be con- nected in series as shown in FIG. 2. The light-control instruction input (DIN) and the light-control instruction output (DOUT) of adjacent light-emitting elements (LED_1-LED_N) are cascaded accordingly. For exam- ple, the light-control instruction input (DIN) of the second light-emitting element (LED_2) is configured to couple with the light-control instruction output (DOUT) of the first light-emitting element (LED_1). In the example, the first light-emitting element (LED_1) receives the light-control instruction (CI) from the light-control instruction source 200 through the light-control instruction input (DIN) of the first light-emitting element (LED_1) and outputs the light- control instruction (CI) from the light-control instruction output (DOUT) of the first light-emitting element (LED_1) to the light-control instruction input (DIN) of the second light-emitting element (LED_2). Accordingly, the light- control instruction (CI) is able to be provided to the light-emitting elements (LED_1-LED_N). 5 10 15 20 25 30 35 40 45 50 55 4 5 EP 4 770 275 A1 6

[0025] In theembodiment, the transmissionof the light- control instruction (CI) is illustrated in FIG. 3. When the light-control instruction (CI) is configured to control the first light-emitting element group 300 having a first num- ber (N) of light-emitting elements, the light-control in- struction (CI) includes data signals corresponding to the first light-emitting element (RGB1), the second light-emitting element (RGB2), ..., and the N-th light- emitting element (RGBN), and a latch signal. As such, the N light-emitting elements of the first light-emitting element group 300 are configured to emit light based on the light-control instruction (CI).

[0026] However, when the light-control instruction (CI) is used to control a second light-emitting element group 400 having a second number (M, where M > N) of light- emitting elements, the data signal and / or the latch signal of the light-control instruction (CI) are insufficient to con- trol all light-emitting elements of the second light-emitting element group 400. In other words, the light-control in- struction (CI) provided by the light-control instruction source 200 is unable to control the light-emitting ele- ments of the second light-emitting element group 400 beyond the first number (N), i.e., LED_N+1 through LED_M. In such a case, referring to FIG. 4, the light- control instruction extension device 100 is configured to be connected between the light-control instruction source 200 and the second light-emitting element group 400. The processing unit 120 of the light-control instruc- tion extension device 100 is configured to extend the light-control instruction (CI) into an extended light-control instruction (ECI) and outputs it to the second light-emit- ting element group 400. The processing unit 120 may be an MCU, ASIC, FPGA, or any component capable of instruction reading / processing. The processing unit 120 is configured to read the light-control instruction (CI) corresponding to the first number (N) of light-emitting elements and extend the light-control instruction (CI) into the extended light-control instruction (ECI) correspond- ing to the second number (M) of light-emitting elements using the extension method described herein.

[0027] In an embodiment of the extension of the light- control instruction (CI), theprocessingunit 120 repeats at least a portion of the light-control instruction (CI) to gen- erate the extended light-control instruction (ECI). Refer- ring to FIG. 5, the processing unit 120 is configured to repeat, at least once, at least a portion of the data signals corresponding to the first light-emitting element (RGB1), the second light-emitting element (RGB2), ..., and / or the N-th light-emitting element (RGBN). Therefore, the amount of data signals in the extended light-control in- struction (ECI) is enough to correspond to the second number (M). Specifically, in FIG. 5, the data signal RGB1 is repeated once, thereby making the quantity of data signals in the extended light-control instruction (ECI) equal to the second number (M). It should be noted that FIG. 5 ismerely illustrative and does not limit the portions or number of repetitions of the light-control instruction (CI). Moreover, the number of corresponding signals in the extended light-control instruction (ECI) is not limited to the second number (M) and may be any number Y greater than M (Y > M).

[0028] In another embodiment of extending the light- control instruction (CI), the number of repetitions of at least a portion of the light-control instruction (CI) per- formed by the processing unit 120 is equal to a quotient obtained by dividing the second number by the first number (i.e. M / N). Referring to FIG. 6, for a light-control instruction (CI) corresponding to the first number (N), repetition is performed according to the quotient (M / N). As an example, when the light-control instruction source outputs a light-control instruction (CI) capable of control- ling only 80 light-emitting elements (N = 80), but the second light-emitting element group has 240 light-emit- ting elements (M = 240), the processing unit 120 is configured to repeat data signals (RGB1-RGB80) three times to generate the extended light-control instruction (ECI). Thus, when the light-control instruction source is insufficient to support the lighting effects of the second light-emittingelementgroup400, the light-control instruc- tion extension device 100 is configured to extend the light-control instruction (CI) into the extended light-con- trol instruction (ECI) configured to support the lighting effects of the second light-emitting element group 400.

[0029] In an embodiment of repeating the light-control instruction (CI), the processing unit 120 is further config- ured to receive an adjustment command, wherein the adjustment command specifies the number of repetitions (i.e. repetition count) of at least a portion of the light- control instruction (CI). For example, the processing unit 120 is configured to receive the adjustment command provided by a user or a controller via wired means (e.g., signal lines) or wireless means (e.g., Bluetooth). The adjustment command is configured to instruct the num- ber of repetitions of at least a portion of the light-control instruction (CI). For example, if the quotient between the second number (M) and the first number (N) cannot be predetermined or the number of repetitions of at least a portion of the light-control instruction (CI) is not preset in the processing unit 120, the adjustment command is configured to set the number of repetitions of the light- control instruction (CI) to map the first number (N) to the second number (M) after the light-control instruction source 200 and the second light-emitting element group 400 are configured. As a further example, if the adjust- ment command indicates four repetitions, theadjustment command causes the processing unit 120 to increase the number of data signals from N to 4N. It should be noted that the adjustment command may be set based on the actual number of light-emitting elements to be controlled. For instance, the repetition count may be calculated by dividing M by N or by rounding up to obtain an integer repetition value.

[0030] In an embodiment of the present invention, referring to FIGs. 7‑8, an instruction set is provided for the light-control instructionextensiondevice.The instruc- tion set is stored in a storagemedium (e.g. memory, hard 5 10 15 20 25 30 35 40 45 50 55 5 7 EP 4 770 275 A1 8 disk or cache).When a processing unit reads the instruc- tion set from the storage medium, the instruction set causes the processing unit to execute a light-control instruction extension method 500. The light-control in- struction extensionmethod500 includes: (StepS1) read- ing a light-control instruction; and (Step S2) repeating at least a portion of the light-control instruction according to a repetition count.

[0031] It should be noted that the instruction set for the light-control instruction extension device may also in- clude instructions for signal transmission, such as initi- alization instructions for SPI or I2C. Thus, each light- emitting element of the light-emitting element group may be controlled using data transmission protocols such as SPI or I2C.

[0032] In an embodiment, the light-control instruction corresponds to a first number of light-emitting elements, and the repetition count is an integer multiple of the first number.

[0033] In an embodiment, the instruction set further causes the processing unit to read an adjustment com- mand indicating the repetition count.

[0034] In summary, through the light-control instruction extension device and the instruction set of the present invention, a light-control instruction provided by a light- control instruction sourcemaybeextended. Thus, a light- control instruction originally corresponding to the control of a first number of light-emitting elements may be ex- tended to control a second number of light-emitting ele- ments.

[0035] The foregoing description of the present inven- tion is provided to enable a person skilled in the art to make or use the invention. Various modifications to the invention will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other variations without departing from the spirit or scope of the invention.
