Description

Technical Field

[0001] The present invention relates to the technical field of light emitting device control, and in particular to a control method, device and controller for a light emitting device. Background Art

[0002] In actual use, visible light communication networks need to balance the needs of both communication and lighting. If only the strength of the communication signal is considered, it is usually unable to meet the demand for continuous and stable lighting. At the same time, lighting brightness will also change with user needs, so the actual application of visible light communication networks needs to take lighting needs into consideration. Therefore, visible light communication networks need to introduce dimming technology to achieve both communication and lighting functions. Currently, the existing dimming technologies in visible light communication mainly include the following methods:

[0003] Add compensation symbols: When the data transmission intensity cannot meet the light brightness requirement, the average light intensity can be increased by adding compensation symbols before the transmission symbols, thereby achieving the purpose of meeting the lighting requirements;

[0004] Control pulse width: Control light intensity by controlling the width of visible light pulses. Within a fixed period, the length of the pulse width can control the intensity of light. The longer the width, the greater the light intensity.

[0005] Specifically, for RBG-LEDs, each color uses a fixed time sequence within a cycle. Since the actual pulse width (PW) within each time sequence is variable, the brightness and color of the light can be controlled by changing the actual pulse width of each color LED light.

[0006] Control pulse amplitude: Control light intensity by controlling the amplitude of visible light pulses.

[0007] Current visible light dimming technology is primarily designed based on the lighting and communication needs of a single lamp. In a visible light networking environment, if multiple light panels or lamp beads use the same dimming method and frequency, or if they dim independently, this will significantly increase the interference level during visible light communication, thereby reducing communication transmission efficiency. For example, if multiple light panels or lamp beads use the same pulse frequency and position for dimming, then at high pulse rates, there will inevitably be strong interference between the multiple lamps. Summary of the Invention

[0008] The technical problem to be solved by the present invention is how to provide a control method, device and controller for a light-emitting device. The method of collaborative dimming between multiple visible light lamps is used to reduce the interference level during communication and further improve the transmission efficiency of visible light communication.

[0054] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0055] like Figure 1 As shown, an embodiment of the present invention provides a method for controlling a light emitting device, the method comprising:

[0056] Step 11, generating a control instruction for controlling the at least two light-emitting devices to emit light according to the light board where the at least two light-emitting devices are located;

[0057] Step 12: Control the at least two light-emitting devices to emit light according to the control instruction, and ensure that the interference between the at least two light-emitting devices is lower than a preset value.

[0058] Here, the light-emitting device is specifically described. The light-emitting device includes multiple ones. The first light-emitting device in the following embodiments of the present invention can be a light-emitting device commonly used in daily lighting scenes, including RBG-LED, OLED, etc., among which REG-LED (RedBlue Green Light-Emitting Diode) is a light-emitting diode that uses the three primary colors of red, green and blue to form an image, and OLED (Organic Light-Emitting Diode) is an organic light-emitting diode; for the first light-emitting device, its lighting efficiency is high, but its communication capability is not strong. Specifically, there is RBG-LED, whose spectral bandwidth available for each wavelength is only 20-30MHz. In the embodiment of the present invention, when the first light-emitting device is set on the light board, there can be multiple;

[0059] The second light-emitting device can be a micro-LED (micro-LED) specifically developed for visible light communication. This second light-emitting diode offers significantly improved communication capabilities compared to the first device, with a bandwidth of up to 400-500 MHz, significantly increasing communication rates. However, its luminous efficiency is low, and its self-luminous properties result in low brightness, making it difficult to use as a lighting device. In embodiments of the present invention, multiple second light-emitting devices can be provided on the light panel.

[0060] Therefore, in actual use, the first light-emitting device and the second light-emitting device need to be used in conjunction with each other.

[0061] In an optional embodiment of the present invention, control instructions for the first light-emitting device and the second light-emitting device are generated based on the lamp board where the first light-emitting device and the second light-emitting device among the at least two light-emitting devices are located, and the communication transmission capability of the second light-emitting device is greater than the communication transmission capability of the first light-emitting device.

[0062] In this embodiment, a control instruction for controlling light emission is generated by the light board where the first light emitting device and the second light emitting device are located, and light is emitted according to the control instruction, thereby realizing collaborative dimming control of the light emitting devices. This can not only take into account lighting needs, but also reduce interference and improve transmission efficiency during networking. It should be noted that the first light emitting device and the second light emitting device here represent different types of light emitting devices. In an optional embodiment of the present invention, step 11 includes:

[0063] Step 111: if the first light emitting device and the second light emitting device are in the same light panel, determine a first frequency range of the first light emitting device and a second frequency range of the second light emitting device;

[0064] Step 112: Generate a first control instruction for controlling the first light emitting device and the second light emitting device to emit light according to the first frequency range and the second frequency range.

[0065] like Figure 2 As shown, in this embodiment, the first light-emitting device and the second light-emitting device are integrated in the same lamp board and used together for collaborative dimming. In the figure, the ordinary LED lamp 21 is the first light-emitting device, and the micro light-emitting diode μLED22 is the second light-emitting device. The first light-emitting device provides lighting, and the second light-emitting device provides communication transmission function.

[0066] When the first light emitting device and the second light emitting device are on the same light board, there are two solutions depending on whether the lighting and communication frequencies are the same:

[0067] Solution 1: When the first light emitting device and the second light emitting device have the same frequency:

[0068] If the first frequency range and the second frequency range are the same frequency range, a first control instruction is generated to control the first light-emitting device and the second light-emitting device to emit light. The first control instruction is used to control the second light-emitting device to maintain the lighting intensity when it is in an idle state; when the second light-emitting device is in a transmission state, the first light-emitting device emits light at a first frequency, and the second light-emitting device emits light at a second frequency, and the first light-emitting device and the second light-emitting device switch to emit light to maintain an average light intensity; wherein the first light-emitting device emits light at a brightness higher than the required light intensity, and the second light-emitting device performs communication transmission at a lower brightness to meet communication requirements.

[0069] In this embodiment, when the second light-emitting device is in an idle state, the first light-emitting device maintains the illumination intensity to provide lighting requirements. When the second light-emitting device is in a transmitting state, the first and second light-emitting devices switch illumination at a certain frequency to maintain an average light intensity to provide lighting requirements. The first light-emitting device emits at a brightness higher than the required light intensity, while the second light-emitting device transmits communication at a lower light intensity to meet communication requirements.

[0070] like Figure 3 As shown in a specific embodiment 1, taking two lamp beads as an example, lamp bead A is an LED lamp bead for general lighting (the first light-emitting device), and lamp bead B is a lamp bead dedicated to communication (the second light-emitting device). Lamp beads A and lamp bead B have the same frequency. CS (compensation symbols) are compensation symbols, RF (resync field) is the synchronization field, DS (data symbol) is the data symbol, AB (average brightness) is the average light intensity, N% is the average light intensity AB maintained by lamp beads A and lamp bead B within a certain frequency, and D% is the lower light intensity that meets communication requirements. Assuming the required lighting intensity is 50%, the average light intensity of lamp beads A and lamp bead B within a time period must be N% ≥ 50% to meet the required lighting intensity.

[0071] like Figure 3 As shown, in the idle state, lamp bead B does not communicate, the lighting intensity of lamp bead A is N%, and the average light intensity of lamp bead A and lamp bead B is N%. Since the average light intensity N% is not less than 50% of the set required lighting intensity, the lighting needs are met during the idle time.

[0072] When lamp bead B needs to transmit data, if lamp bead A still maintains 50% light intensity, it will cause two problems: first, lamp bead A will cause light noise interference to lamp bead B when it is lighting, affecting the data transmission efficiency of lamp bead B; second, the sudden increase in light intensity of lamp bead B used for data transmission will affect the overall lighting intensity, causing discomfort to the human eye.

[0073] Therefore, lamp beads A and B can be used as follows Figure 3 The method shown is to switch the light emission at a certain frequency to maintain the average light intensity. In one cycle, lamp bead A emits light with an intensity higher than the average light intensity N% (that is, the part shown by the compensation symbol CS). After a period of time, it switches to lamp bead B to emit light with an intensity lower than the average light intensity for communication transmission (that is, in the RF+DS time period, the intensity lower than the average light intensity is used for communication transmission). However, in one cycle, the average light intensity N% of lamp bead A and lamp bead B collaborative dimming meets 50% of the required lighting intensity (that is, the average light intensity N% ≥ 50%). This can not only meet the light intensity requirements of lighting, but also avoid lamp bead A and lamp bead B emitting light at the same time, which will cause noise interference.

[0074] Solution 2: When the first light emitting device and the second light emitting device have different frequencies:

[0075] If the first frequency range and the second frequency range are different frequency ranges, a first control instruction is generated to control the first light-emitting device and the second light-emitting device to emit light. The first control instruction is used to control the second light-emitting device to maintain the lighting intensity when it is in an idle state; when the second optical device is in a transmission state, the first light-emitting device and the second light-emitting device simultaneously emit light at different light intensities to maintain an average light intensity, wherein the first light-emitting device emits light at a brightness higher than the required light intensity; and the second light-emitting device performs communication transmission at a lower brightness to meet communication requirements.

[0076] In this embodiment, when the second light-emitting device is in an idle state, the first light-emitting device maintains the illumination intensity to provide lighting requirements. When the second optical device is in a transmission state, the first and second light-emitting devices simultaneously emit light at different intensities to maintain an average light intensity to provide lighting requirements. The first light-emitting device emits light at a brightness higher than the required intensity, while the second light-emitting device transmits communication at a lower intensity to meet communication requirements.

[0077] like Figure 4 As shown in a specific embodiment 2, taking two lamp beads as an example, lamp bead A is an LED lamp bead for general lighting (the first light-emitting device), and lamp bead B is a lamp bead dedicated to communication (the second light-emitting device). Lamp bead A and lamp bead B are different frequencies. CS (compensation symbols) are compensation symbols, RF (resync field) is the synchronization field, DS (data symbol) is the data symbol, AB (average brightness) is the average light intensity, N% is the average light intensity maintained by lamp bead A and lamp bead B within a certain frequency, and E% is a lower light intensity that is lower than the average intensity but meets the communication requirements. Assuming that the required lighting intensity is 50%, the average light intensity N% of lamp bead A and lamp bead B collaborative dimming must not be less than 50% of the set required lighting intensity to meet the required lighting intensity.

[0078] like Figure 4 As shown, in the idle state, lamp bead B does not communicate, the lighting intensity of lamp bead A is N%, and the average light intensity of lamp bead A and lamp bead B collaborative dimming is N%. Since the average light intensity N% is not less than 50% of the set required lighting intensity, the lighting needs are met during the idle time.

[0079] When lamp bead B needs to transmit data, if lamp bead A still maintains 50% brightness, the sudden increase in the light intensity of lamp bead B used for data transmission will affect the overall lighting brightness and cause discomfort to the human eye.

[0080] Therefore, lamp beads A and B can be used as follows Figure 4 In the manner shown, when lamp bead B starts communicating, lamp bead A reduces the light intensity to E%, and the light intensity of lamp bead B is D%. Under the coordinated action of lamp bead A and lamp bead B, the average light intensity N% is not less than 50% of the required lighting demand, that is, the overall brightness of lamp bead A and lamp bead B meets the required lighting brightness. This not only meets the light intensity required for lighting, but also reduces noise interference.

[0081] In an optional embodiment of the present invention, step 11 includes:

[0082] Step 113: If the at least two light-emitting devices are in different light boards, a second control instruction is generated to control the third light-emitting device in the first light board and the fourth light-emitting device in the second light board to emit light. The second control instruction is used to control the pulse positions of the third light-emitting device and the fourth light-emitting device to be different within the same time period.

[0083] In this embodiment, the third light-emitting device and the fourth light-emitting device are used in combination in different lamp panels to generate a second control instruction for controlling the light emission, and emit light according to the second control instruction, thereby realizing collaborative dimming control of the light-emitting devices. It should be noted that there are multiple third light-emitting devices and multiple fourth light-emitting devices here.

[0084] When the third light emitting device and the fourth light emitting device are on different light boards, there are three solutions according to the function of the second control signaling:

[0085] Solution a, staggered pulse position collaborative dimming:

[0086] The second control signaling is used to control the different pulse positions of the third light-emitting device and the fourth light-emitting device within the same time period; the second control instruction includes: a first pulse position control instruction indicating the pulse position of the third light-emitting device and a second pulse position control instruction indicating the pulse position of the fourth light-emitting device, the first pulse position control instruction and the second pulse position control instruction are semi-static high-level signaling or dynamic control signaling.

[0087] In this embodiment, when networking, the pulse positions between multiple light boards are considered and staggered. Each light board transmits data during high pulses to reduce interference. The pulse positions between multiple light boards are uniformly coordinated and controlled by a central controller, and each light board is notified through special signaling.

[0088] For visible light terminals, the pulse position (i.e., data transmission time slot) of the serving light panel can be semi-statically notified by higher-layer signaling, such as RRC (Radio Resource Control), or dynamically notified by control signaling, such as DCI (Downlink Control Information). When the pulse amplitude is not adjustable, it is suitable for scenarios with lower brightness requirements. The smaller the duty cycle of a single light panel, the more light panels can be staggered.

[0089] like Figure 5 and Figure 6 As shown, in a specific embodiment 3, taking two adjacent light panels AP as an example, if the two light panels use the same pulse position and frequency to dim independently, such as Figure 5 As shown in FIG, the pulse positions and frequencies of the light board AP1 and the light board AP2 are consistent, so these two light board APs will generate strong mutual interference during data transmission, which will reduce the communication efficiency of the entire network.

[0090] Therefore, the central controller can coordinate and control the pulse positions of the two light boards to be staggered, such as Figure 6 As shown in the figure, during a period of time, when AP1 is communicating at high brightness, AP2 is in an idle state; when AP1 switches to an idle state, AP2 begins data communication. This can prevent interference between AP1 and AP2 by designing the pulse positions of the multi-light board, thereby improving network performance.

[0091] Solution b: Adjust pulse amplitude for collaborative dimming:

[0092] The second control instruction is also used to control the pulse amplitudes of the third light-emitting device and the fourth light-emitting device to be different within the same time period; the second control instruction also includes: a first pulse amplitude control instruction indicating the pulse amplitude of the third light-emitting device and a second pulse amplitude control instruction indicating the pulse amplitude of the fourth light-emitting device, the first pulse amplitude control instruction and the second pulse amplitude control instruction are semi-static high-level signaling or dynamic control signaling.

[0093] In this embodiment, when networking, the pulse positions and amplitudes between multiple light boards are considered for staggered design, and each light board transmits data during high pulses to reduce interference; the pulse positions and pulse amplitudes between multiple light boards are uniformly coordinated and controlled by the central controller, and each light board is notified through special signaling.

[0094] For visible light terminals, the pulse position (i.e., data transmission time slot) of the service light board can be semi-statically notified by high-level signaling, such as RRC; or dynamically notified by control signaling, such as DCI; when the pulse amplitude can be adjusted, combined with the pulse position staggered design, it is suitable for scenarios with higher brightness requirements, reducing the duty cycle of a single light board and staggering more light boards.

[0095] In a specific embodiment 4, taking two adjacent light panels AP as an example, solution a is used in a scenario with relatively low lighting brightness requirements. When the duty cycle of each light panel is not high (at least not more than 50%), at least two light panels can be staggered in one cycle. When the lighting brightness requirements are relatively high and the duty cycle of each light panel is relatively high, the two light panels cannot be completely staggered, and interference will still exist, such as Figure 7 As shown in Figure 1, the duty cycle of light board AP1 and light board AP2 is greater than 50%, and the average light intensity of light board AP1 and light board AP2 is 60%. The two light boards cannot use solution a to achieve control dimming by adjusting the pulse position. There is a situation where the brightness of light board AP1 and light board AP2 is 100% at the same time, that is, Figure 7 At the intersection of the middle shaded areas, there is interference.

[0096] Therefore, the central controller can coordinate and control the pulse position and pulse amplitude of the two light boards at the same time, reduce the duty cycle of a single light board, and thus stagger the data transmission time of the two light boards.

[0097] like Figure 8 As shown in the figure, 100% brightness is high brightness, 40% is low brightness, and the average light intensity of light board AP1 and light board AP2 is 60%. When light board AP1 is at high brightness and communicating, light board AP2 is at low brightness and not communicating. At this time, the light intensity of light board AP2 does not carry communication information and can be treated as noise relative to the data of light board AP1. This can prevent demodulation interference between light boards AP1 and AP2, thereby improving network performance.

[0098] Solution c: Collaborative dimming between two adjacent multi-color light-emitting device panels:

[0099] When the third light-emitting device or the fourth light-emitting device is a multi-color light-emitting device, the second control instruction further includes: pulse width information indicating different colors in the same cycle of the multi-color light-emitting device.

[0100] In this embodiment, for multi-color light-emitting devices, within the same cycle, the pulse widths of different colors can be adjusted separately to control the brightness and color of the lamp; the positions of light wave pulses of different wavelengths between multiple lamp panels are staggered to avoid interference. In a specific embodiment, the multi-color light-emitting device is preferably an RBG-LED light-emitting device.
