Description

Technical Field

[0001] This application relates to the technical field of light-emitting devices, and in particular to a control method for a light-emitting device and a light-emitting device. Background Technology

[0002] In related technologies, light-emitting devices sometimes need to be covered with light-transmitting components such as diffusers or filters. However, when these components are installed, the light-emitting effect may sometimes fail to meet requirements. Summary of the Invention

[0003] This application provides a control method for a light-emitting device, a storage medium, and a light-emitting device, which can improve the light-emitting effect of the light-emitting device.

[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a control method for a light-emitting device, comprising the following steps:

[0005] The light emission state of the light emission device is obtained; wherein the light emission state includes a first state and a second state, in which the light emission device illuminates the object to be illuminated in the first state, and in the second state the light emission device illuminates the object to be illuminated through the light-transmitting component;

[0006] Acquire the switching signal of the light emission state. When the light emission state switches from the first state to the second state, acquire the light emission parameters of the light emission device and mark them as the first light emission parameters.

[0007] A second luminous parameter, different from the first luminous parameter, is generated based on the first luminous parameter, and the luminous device emits light with the second luminous parameter.

[0008] In some embodiments, the first light emission parameter includes at least one of the following parameters: hue, saturation, and brightness of the light emitted by the light emission device.

[0009] In some embodiments, the light-transmitting component includes at least one of a diffuser, a filter, or a gradient sheet.

[0010] In some embodiments, under the first light emission parameters and the first state of the light emission device, the light received by the object to be irradiated has a first light reception parameter;

[0011] Under the first luminescence parameters and the second state of the luminescence device, the light received by the object to be irradiated has a second light-receiving parameter;

[0012] In the second luminescence parameter and the second state of the luminescence device, the light received by the object to be irradiated has a third light-receiving parameter;

[0013] The third light-receiving parameter is closer to the first light-receiving parameter than the second light-receiving parameter.

[0014] In some embodiments, after the step of obtaining the light emission state of the light-emitting device, the method further includes:

[0015] Acquire the switching signal of the light emission state. When the light emission state switches from the second state to the first state, acquire the light emission parameters of the light emission device and mark them as the third light emission parameters.

[0016] A fourth emission parameter, different from the third emission parameter, is generated based on the third emission parameter, and the light-emitting device emits light using the fourth emission parameter.

[0017] In some embodiments, the light received by the object to be irradiated has a fourth light-receiving parameter under the third light-emitting parameter and the second state of the light-emitting device;

[0018] In the third luminescence parameter and the first state of the luminescence device, the light acquired by the object to be irradiated has a fifth light reception parameter;

[0019] In the fourth luminescence parameter and the first state of the luminescence device, the light acquired by the object to be irradiated has a sixth light-receiving parameter;

[0020] The sixth light-receiving parameter is closer to the fourth light-receiving parameter than the fifth light-receiving parameter.

[0021] In some embodiments, the light-emitting device includes a trigger switch, and the step of triggering the trigger switch when the light-transmitting component is installed in the light-emitting device, and obtaining a switching signal of the light-emitting state, includes:

[0022] Whether the trigger switch is triggered is determined. When the trigger switch is triggered, a switching signal is generated to switch the light emission state from the first state to the second state.

[0023] A second aspect of this application also provides a light-emitting device capable of housing a light-transmitting component, the light-emitting device comprising:

[0024] Light-emitting elements are used to emit light.

[0025] The first mounting section is used to install light-transmitting components;

[0026] The sensor can sense whether a light-transmitting component is installed on the first mounting part. When the first mounting part is not equipped with a light-transmitting component, it generates a first signal and when the first mounting part is equipped with a light-transmitting component, it generates a second signal.

[0027] The control processor, coupled to the sensor, is able to acquire a first signal and a second signal. When the control processor acquires the first signal, it acquires the first light-emitting parameters of the light-emitting element and generates the second light-emitting parameters based on the first light-emitting parameters.

[0028] Specifically, when the signal acquired by the control processor is switched from the first signal to the second signal, the light emission parameters of the control light-emitting element are switched from the first light emission parameters to the second light emission parameters.

[0029] In some embodiments, the sensor is also configured to sense the type of the light-transmitting component;

[0030] The control processor is configured to generate a second light emission parameter based on the first light emission parameter and the type of the light-transmitting component.

[0031] In some embodiments, the light-transmitting component includes at least one of a diffuser, a filter, or a gradient sheet.

[0032] In some embodiments, the first mounting part includes a slot for engaging a light-transmitting component;

[0033] The sensor is located inside the card slot.

[0034] In some embodiments, the sensor includes a micro switch, the sensor is normally open, and the sensor is configured to be pushed to a closed state by the light-transmitting component when the light-transmitting component is engaged in the slot, the sensor generates a first signal when it is open, and generates a second signal when it is closed.

[0035] The control method provided in this application adjusts the luminous parameters of the light-emitting device when the luminous state of the device switches from a first state to a second state. Since the parameters of the light emitted by the device change when it switches from directly illuminating the object to illuminating it through a light-transmitting component, and the changed luminous parameters may not meet user needs, this application adjusts the luminous parameters after the light emitted by the device switches from directly illuminating the object to illuminating it through a light-transmitting component. The original first luminous parameter is changed to the second parameter, making the adjusted luminous parameters more suitable for user needs and improving the luminous effect. Furthermore, this control method can automatically switch the luminous parameters without requiring manual adjustment by the user, making it convenient to operate.

[0036] The light-emitting device provided in this application has a sensor capable of detecting whether a light-transmitting component is installed on the first mounting part. When the control processor receives a signal that the first mounting part is not equipped with a light-transmitting component, it acquires the first light-emitting parameters of the light-emitting element and generates a second light-emitting parameter based on the first light-emitting parameter. Upon receiving a signal that the first mounting part has changed from a state without a light-transmitting component to a state with a light-transmitting component, the control processor immediately controls the light-emitting parameters of the light-emitting element to switch from the first light-transmitting parameter to the second light-transmitting parameter. In other words, when a light-transmitting component is installed in the light-emitting device, the control processor can adjust the light-transmitting parameters of the light-emitting element accordingly, so that the light received by the object to be irradiated can better meet the requirements. This process does not require manual adjustment by the user and is convenient to operate. Attached Figure Description

[0044] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed to" another element, it can be directly on the other element, or one or more intermediate elements may exist between them. When an element is described as being "connected" to another element, it can be directly connected to the other element, or one or more intermediate elements may exist between them. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this specification are for illustrative purposes only.

[0045] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0046] A light-emitting device is a device used to generate light. Specifically, a light-emitting device can be a lighting device or a projection device, etc. For ease of description, the following explanation will use a lighting device as an example, specifically a photographic light.

[0047] The applicant has discovered that in related technologies, during photography, sometimes a camera light is needed to directly illuminate the subject, and sometimes a diffuser or similar device is needed in front of the camera light to illuminate the subject. However, when an operator initially uses a camera light to directly illuminate the subject, and then, for some reason, needs to add a diffuser or similar device to illuminate the subject again, the hue, saturation, and brightness of the light received by the subject after passing through the diffuser will change. At this point, the operator needs to readjust the light emission parameters of the lighting equipment to ensure that the light received by the subject is ideal. This process is quite cumbersome.

[0048] In view of this, see Figure 1 This application provides a control method for a light-emitting device, which specifically includes the following steps:

[0049] Step S102: Obtain the light emission state of the light emission device. The light emission state includes a first state and a second state. In the first state, the light emission device illuminates the object to be illuminated. In the second state, the light emission device illuminates the object to be illuminated through the light-transmitting component.

[0050] In this step, it is possible to identify whether the light emitted by the photographic lamp passes through the light-transmitting component and illuminates the object to be illuminated. Specifically, in one embodiment, the light-emitting device can be equipped with an image recognition device to identify whether a light-transmitting component is placed in front of the photographic lamp's light-emitting device. In one embodiment, a first sensor can be placed on the light-transmitting device, and a second sensor can be placed on the photographic lamp. When the light-transmitting component is placed in front of the photographic lamp, the first sensor can detect the presence of the second sensor, thereby identifying whether a light-transmitting component is placed in front of the photographic lamp (this solution can also identify the type and model of the light-transmitting component). It should be noted that the device for obtaining the light emission state of the light-emitting device can be a device on the light-emitting device or not. When the device for obtaining the light emission state of the light-emitting device is not a device on the light-emitting device, a separate recognition device needs to be set up to obtain the light emission state of the light-emitting device, and the above-mentioned recognition device can be communicatively connected with the light-emitting device. How to identify whether the light emitted by the light-emitting device passes through the light-transmitting component and illuminates the object to be illuminated will be supplemented later, and will not be elaborated here.

[0051] It should be noted that in this application, the light-emitting device is in the second state when the light received by the irradiated object is light that passes through the light-transmitting component. The light-emitting device is in the first state when the light received by the irradiated object does not pass through the light-transmitting component. Even if the light emitted by the light-emitting device does not directly illuminate the irradiated object, but is reflected to the irradiated object through other light-emitting components, the light-emitting device is still in the first state.

[0052] Step S104: Obtain the switching signal of the light emission state. When the light emission state switches from the first state to the second state, obtain the light emission parameters of the light emission device and mark them as the first light emission parameters.

[0053] In this step, when the light emitted by the light-emitting device directly illuminates the object without passing through the light-transmitting component, the process switches to the light emitted by the light-emitting device illuminating the object through the light-transmitting component (i.e., the light emission state switches from the first state to the second state). The light emission parameters of the light-emitting device are then acquired and marked as the first light emission parameter. The first light emission parameter is the parameter of the light emitted by the light-emitting device illuminating the object without passing through the light-transmitting component. However, at this time, the light-emitting device is in the second state, meaning the light emitted by the light-emitting device illuminates the object through the light-transmitting component. Therefore, when the light emission parameter of the light-emitting device is set to the first light emission parameter, the light received by the object is insufficient for the shooting requirements. The light emission parameters of the light-emitting device need to be adjusted.

[0054] Step S106: Generate a second light emission parameter that is different from the first light emission parameter according to the first light emission parameter, and make the light emission device emit light with the second light emission parameter.

[0055] In this step, after obtaining the first luminescence parameter, a second luminescence parameter, which is different from the first luminescence parameter, is generated based on the first luminescence parameter. When both the first and second luminescence parameters have multiple parameters, they are considered different if they differ in even one parameter. For example, when both the first and second luminescence parameters include three parameters: hue, saturation, and lightness, the first and second luminescence parameters are considered different if they differ only in lightness.

[0056] After generating the second emission parameter, the light-emitting device emits light according to this parameter. This ensures that the subject receives sufficient light for the shot, improving the light emission effect of the device. This parameter adjustment is automatic, eliminating the need for manual adjustment by the user and making the process convenient and quick, thus improving shooting efficiency.

[0057] The first luminescence parameter can consist of any parameter that can define the luminescence effect of the luminescence device. The first luminescence parameter may include one parameter or multiple parameters. Specifically, the luminescence parameter of the luminescence device may be the parameter of the light emitted by the luminescence device (the parameter of the actually emitted light) or the parameter used to make the luminescence element of the luminescence device produce light (the parameter of the light to be emitted).

[0058] When the luminescence parameters refer to the parameters of the light emitted by the light-emitting device, the luminescence parameters can be at least one of the hue, saturation, or brightness of the emitted light. The light-emitting device can be equipped with sensors to acquire the light emitted by the light-emitting element, and then the luminescence parameters can be analyzed using the acquired light.

[0059] When the light emission parameter is a parameter used to cause the light-emitting element of a light-emitting device to produce light, in one embodiment, the light emission parameter can be a parameter such as voltage or current that controls the light emission of the light-emitting element. In another embodiment, the light emission parameter can also be at least one of the parameters such as hue, saturation, or brightness of the light that the light-emitting element is expected to emit (the parameters of the expected emitted light may differ from the parameters of the actually emitted light). In this embodiment, the first light emission parameter includes at least one of the parameters of hue, saturation, and brightness of the light emitted by the light-emitting device. Similarly, all subsequent light emission parameters can also have the same parameter type as the first light emission parameter.

[0060] A light-transmitting component is a component capable of transmitting light emitted by a light-emitting device. The light-transmitting component processes the light emitted by the light-emitting device by allowing it to pass through, thereby meeting the light emission requirements. In other words, any component used to process the light transmitted by the light-emitting device before illuminating the object to be illuminated can be called a light-emitting component in this application. Exemplarily, a light-transmitting component may include at least one of a diffuser, a filter, or a graduated filter. In this embodiment, a diffuser is used as an example. After the light emitted by the light-emitting device passes through the diffuser, the light becomes more uniform and softer. However, compared to not using a diffuser, the saturation and brightness of the light received by the object to be illuminated decrease after using a diffuser. Therefore, in subsequent adjustments, it is necessary to increase the saturation and brightness of the light emitted by the light-emitting device to meet the subsequent shooting requirements.

[0061] The applicant has discovered that, for photographic lights, sometimes it is required that the parameters of the light received by the subject be consistent before and after the installation of a light-transmitting component. However, sometimes this consistency is not required. For example, when the light-transmitting component is a red filter, it is generally desirable that the hue of the light received by the subject be more reddish. In this case, installing a red filter makes the hue parameter of the second emission parameter more reddish than the hue parameter of the first emission parameter. Therefore, the parameters of the light received by the subject are not consistent before and after the installation of the light-transmitting component.

[0062] When it is required that the parameters of the light received by the subject before and after the light-transmitting component is set or not be consistent, specifically, under the first light-emitting parameters and the first state of the light-emitting device, the light received by the object to be illuminated has a first light-receiving parameter. Under the first light-emitting parameters and the second state of the light-emitting device, the light received by the object to be illuminated has a second light-receiving parameter. Under the second light-emitting parameters and the second state of the light-emitting device, the light received by the object to be illuminated has a third light-receiving parameter. The third light-receiving parameter is closer to the first light-receiving parameter than the second light-receiving parameter. That is, the goal of this embodiment is to make the third light-receiving parameter completely consistent with the first light-receiving parameter, so that the parameters of the light received by the subject before and after the light-transmitting component is set or not be consistent. However, in reality, it is difficult to make the third light-receiving parameter completely consistent with the first light-receiving parameter, so the third light-receiving parameter can be made closer to the first light-receiving parameter than the second light-receiving parameter.

[0063] It should be noted that if any parameter of the third light-receiving parameter is closer to the first light-receiving parameter than the second light-receiving parameter, then the third light-receiving parameter is considered to be closer to the first light-receiving parameter than the second light-receiving parameter. For example, when the first, second, and third light-receiving parameters all include brightness and saturation, and the brightness value of the first light-receiving parameter is 100, the brightness value of the second light-receiving parameter is 80, and the brightness value of the third light-receiving parameter is 90, then the third light-receiving parameter is considered to be closer to the first light-receiving parameter than the second light-receiving parameter.

[0064] The method for generating a second luminous parameter that differs from the first luminous parameter can be determined according to specific needs. In one embodiment, a lookup table can be pre-configured to generate the second luminous parameter. For example, when the first luminous parameter only includes brightness, multiple first brightness values ​​can be preset in the lookup table. Each first brightness value corresponds to multiple second brightness values. The first brightness value corresponds to the brightness value of the first luminous parameter in different usage scenarios of the luminous device, and the second brightness value corresponds to the generated second luminous parameter. For example, in the lookup table, a first brightness value of 50 corresponds to a second brightness value of 55, and a first brightness value of 100 corresponds to a second brightness value of 110. When the brightness value of the first luminous parameter is 50 in the first state of the luminous device, after the luminous device switches to the second state (i.e., after a light-transmitting component is set in front of the luminous device), according to the lookup table, a brightness value of 55 for the second luminous parameter can be generated. Subsequently, the brightness value of the light emitted by the luminous device can be adjusted to 55.

[0065] Furthermore, multiple lookup tables can be set up by identifying the type of light-transmitting component. For example, one lookup table can be set up for diffusers, and another for filters. The light-emitting device can search different lookup tables by identifying different types of light-transmitting components.

[0066] In some embodiments, after the step of obtaining the light emission state of the light-emitting device, the method further includes:

[0067] Acquire the switching signal of the light emission state. When the light emission state switches from the second state to the first state, acquire the light emission parameters of the light emission device and mark them as the third light emission parameters.

[0068] A fourth emission parameter, different from the third emission parameter, is generated based on the third emission parameter, and the light-emitting device emits light using the fourth emission parameter.

[0069] In this step, it is possible to identify whether the light emission state has switched from the second state to the first state. When the light emission state switches from the second state to the first state, the parameters of the light received by the object to be photographed also change, and the light emission of the photographic light also needs to be adjusted. The light emission parameters obtained in the second state of the light emission device are marked as the third light emission parameters. After adjusting the third light emission parameters to the fourth light emission parameters, it is more convenient for the light emission device to illuminate the object to be illuminated through the light-transmitting component in the first state.

[0070] In the aforementioned steps, under the third emission parameters and the second state of the light-emitting device, the light received by the object to be irradiated has a fourth light-receiving parameter. Under the third emission parameters and the first state of the light-emitting device, the light received by the object to be irradiated has a fifth light-receiving parameter. Under the fourth emission parameters and the first state of the light-emitting device, the light received by the object to be irradiated has a sixth light-receiving parameter. The sixth light-receiving parameter is closer to the fourth light-receiving parameter than the fifth light-receiving parameter. Similarly, in this scheme, the light received by the object to be irradiated is more consistent whether the light-emitting device has a light-transmitting component or not.

[0071] In order to obtain the light emission state of the light-emitting device, in one embodiment, the light-emitting device includes a trigger switch, and the trigger switch is triggered when the light-transmitting component is installed in the light-emitting device. The step of obtaining the switching signal of the light emission state includes:

[0072] Whether the trigger switch is triggered is determined. When the trigger switch is triggered, a switching signal is generated to switch the light emission state from the first state to the second state.

[0073] In this step, the light-transmitting component is a part installed on the light-emitting device. Therefore, a trigger switch can be installed on the light-emitting device. The trigger switch can be a mechanical switch, which can be triggered when the light-transmitting component is installed on the light-emitting device. Thus, when the trigger switch is not triggered, the light-emitting device is in the first state, and when the trigger switch is not triggered, the light-emitting device is in the second state.

[0074] See Figure 2 The following provides a specific control method.

[0075] Step S201: Obtain the light emission state of the light emission device. The light emission state includes a first state and a second state. In the first state, the light emission device illuminates the object to be illuminated. In the second state, the light emission device illuminates the object to be illuminated through the light-transmitting component.

[0076] Step S202: Obtain the switching signal of the light emission state. When the light emission state switches from the first state to the second state, execute step S203. When the light emission state switches from the second state to the first state, execute step S204.

[0077] Step S203: Obtain the light emission parameters of the light-emitting device and label them as first light emission parameters. Generate second light emission parameters that are different from the first light emission parameters based on the first light emission parameters, and make the light-emitting device emit light with the second light emission parameters.

[0078] Step S204: Obtain the light emission parameters of the light-emitting device and mark them as the third light emission parameters. Generate a fourth light emission parameter that is different from the third light emission parameters based on the third light emission parameters, and make the light-emitting device emit light with the fourth light emission parameters.

[0079] A second aspect of this application also provides a storage medium storing a program for executing the control method described above.

[0080] See Figure 3-6 A third aspect of this application also provides a light-emitting device 100. In one embodiment, the light-emitting device 100 can implement the control method described in the above embodiments. The light-emitting device 100 is capable of mounting a light-transmitting component 200. The light-emitting device 100 includes a light-emitting element 110, a first mounting portion 130, a sensor 140, and a control processor 120. The light-emitting element 110 is used to emit light. The first mounting portion 130 is used to mount the light-transmitting component 200. The sensor 140 can sense whether the light-transmitting component 200 is mounted on the first mounting portion 130. When the light-transmitting component 200 is not mounted on the first mounting portion 130, a first signal is generated. When the light-transmitting component 200 is mounted on the first mounting portion 130, a second signal is generated. The control processor 120 is coupled to the sensor 140 and can acquire the first signal and the second signal. When the control processor 120 acquires the first signal, it acquires the first light-emitting parameters of the light-emitting element 110 and generates the second light-emitting parameters based on the first light-emitting parameters. When the signal acquired by the control processor 120 is switched from the first signal to the second signal, the light emission parameters of the control light-emitting element 110 are switched from the first light emission parameters to the second light emission parameters.

[0081] The sensor 140 can be any known device capable of sensing whether the light-transmitting component 200 is mounted on the first mounting portion 130. The location of the sensor 140 depends on specific requirements; in this embodiment, the sensor 140 is located on the first mounting portion 130. Specifically, the first mounting portion 130 includes a slot 131 for holding the light-transmitting component 200. The sensor 140 is located within the slot 131.

[0082] In this application, the light-emitting device 100 generates a first signal when the sensor 140 does not detect the light-transmitting component 200 mounted on the first mounting portion 130, and transmits the first signal to the control processor 120. The control processor 120, upon receiving the first signal, generates a first light-emitting parameter. The first light-emitting parameter can be at least one of parameters such as hue, saturation, and brightness. When the sensor 140 detects the light-transmitting component 200 mounted on the first mounting portion 130, the sensor 140 generates a second signal and transmits the second signal to the control processor 120. Upon detecting that the signal from the sensor 140 has switched from the first signal to the second signal, the control processor 120 generates a second light-emitting parameter based on the first light-emitting parameter. Similarly, the second light-emitting parameter can be at least one of parameters such as hue, saturation, and brightness. After generating the second light-emitting parameter, the control processor 120 controls the light-emitting element 110 to switch its light-emitting parameter from the first light-emitting parameter to the second light-emitting parameter. This scheme facilitates the automatic adjustment of the light-emitting parameters after the light-transmitting component 200 is mounted on the light-emitting device 100, making operation more convenient.

[0083] In addition to sensing whether the light-transmitting component 200 is installed on the first mounting portion 130, the sensor 140 can also be configured to sense the type of the light-transmitting component 200. The type of the light-transmitting component 200 may include at least one of a diffuser, a filter, or a gradient film. That is, the sensor 140 can sense whether the light-transmitting component 200 installed on the first mounting portion 130 is a diffuser or a filter, etc. To achieve the above objective, in an optional embodiment, image recognition technology can be used to sense the light-transmitting component 200. After the light-transmitting component 200 is installed on the first mounting portion 130, an image of the light-transmitting component 200 is taken and then identified.

[0084] Once the sensor 140 detects the type of the light-transmitting component 200, it transmits this information to the control processor 120. The control processor 120 is configured to generate a second light-transmitting parameter based on the first light-emitting parameter and the type of the light-transmitting component 200. This approach further facilitates fine-tuning of the light emitted by the light-emitting element 110.

[0085] In some embodiments, sensor 140 includes a microswitch. Sensor 140 is normally open and configured to be pushed to a closed state by light-transmitting component 200 when it is engaged in slot 131. Sensor 140 generates a first signal when open and a second signal when closed. In this scheme, the presence or absence of light-transmitting component 200 in the first mounting portion 130 can be sensed by the weight of light-transmitting component 200 or the pressure applied when it is engaged in slot 131. The structure of sensor 140 is simpler, and its placement is more concealed and less prone to damage.

[0086] When the first luminous parameter includes a first brightness and the second luminous parameter includes a second brightness, the second brightness is higher than the first brightness. That is, when the first mounting part 130 is not equipped with the light-transmitting component 200, the brightness of the light emitted by the luminous element 110 is the first brightness. When the first mounting part 130 is equipped with the light-transmitting component 200, the brightness of the light emitted by the luminous element 110 is the second brightness, which is higher than the first brightness, so that the brightness of the light received by the object to be irradiated is more uniform whether the light-transmitting component 200 is installed or not.

[0087] Similarly, when the first luminous parameter includes a first saturation and the second luminous parameter includes a second saturation, the second saturation is higher than the first saturation. That is, when the first mounting portion 130 is not equipped with the light-transmitting component 200, the saturation of the light emitted by the luminous element 110 is the first saturation. When the first mounting portion 130 is equipped with the light-transmitting component 200, the saturation of the light emitted by the luminous element 110 is the second saturation, which is higher than the first saturation, so that the saturation of the light received by the object to be irradiated is more uniform whether the light-transmitting component 200 is installed or not.
