BACKGROUND OF THE PRESENT INVENTION
Field of Invention
The present invention relates to a light fixture, and more particularly to a control system, control method, and its electronic device for a light fixture.
Description of Related Arts
In the field of display, light fixtures or luminaires are commonly used for creating a display effect of the objects to be displayed. For example, when multiple light fixtures are arranged with each, the light fixtures can provide different types of light effects and illuminate the displayed object at different angles. In one application, for displaying a stationary object such as a sale product, the light provided by the light fixtures can enhance the aesthetic appearance of the objects to be displayed. In another application, for displaying a dynamic displayed object (for example the displayed objects can be actors, models, animals, dynamic props, etc.) on a stage, a fashion show walkway and other places, the designer can comprehensively achieve his or her creative idea through the lights provided by the light fixtures.
It is known that the chromaticity (mainly including color temperature and color) and light intensity of the light fixture must match with the surroundings of the displayed object in order to improve the display effect thereof. If the light provided by the light fixture does not match with the surroundings of the displayed object, the display effect will not be enhanced. In fact, it will give negative influences for the displayed object.
For a market place for selling clothing, accessories, and food, the installation angle and lighting of the light fixture are determined and fixed by the designer or the lighting engineer according to the object to be initially displayed. In other words, once the installation angle and lighting of the light fixture are set and fixed, it is difficult to change. However, due to the time change (such as seasonal change), the type of displayed object will be correspondingly changed. When type of displayed object is changed to a new object to be displayed, the installation angle and lighting of the light fixture will mismatch with the new displayed object so as to affect the display effect thereof. It is appreciated that after the displayed object is changed, the installation angle and lighting of the light fixture can be adjusted to match with the new displayed object. However, the ordinary employees, such as salesperson, has lack of lighting distributing knowledge to adjust installation angle and lighting of the light fixture to match with the new displayed object. On the other hand, it is unaffordable for the market place owner to pay additional expenses for experienced designers or lighting engineers to adjust the installation angle and lighting of the light fixture every time when changing the displayed object.
For the places, such as stages and fashion show walkway, the objects must be displayed dynamically. As movements of the displayed objects and the movement change of the objects, the installation angles and lightings of the light fixtures are also different. Therefore, it is required for experienced lighting engineers to operate on the spot in the process of dynamically displaying the displayed objects in a real time manner. However, due to a large number of light fixtures being used in the place, such as the stage or the fashion show walkway, there are several drawbacks for adjusting the light fixtures in a real time manner. Firstly, it is difficult for a single lighting engineer to control a large number of light fixture at the same time. Secondly, even though different numbers of light fixture can be grouped into different light groups for adjusting the light intensities of the light groups by different lighting engineers, the lighting engineers must well communicate with each other to control different light groups as a team. Practically, there will be a defect of mismatching different light groups controlled by different lighting engineers. Once any one of the light groups is mismatched with others, the display effect of the displayed object will be inevitably affected. In addition, the laboring cost of the lighting engineer is often relatively expensive. In other words, by hiring a large number of lighting engineers to control the lamps on the spot, the desired display effect cannot be guaranteed and the cost is relatively expensive.

It is worth mentioning that the optical image involved in the control system 100 of the present invention refers to the image related to the displayed object 300, wherein the optical image can be a visible image or an invisible image, which should not be limited by the control system 100 of the present invention regarding the image.
Nevertheless, a person who skilled in the art should understand that, in another example of the control system 100 of the present invention, an additional or supplemental can be connected to the central processing unit 401 through the user interface 403. It is worth mentioning that the type of the image acquisition device 405 should not be limited in the control system 100 of the present invention, as long as it can acquire the optical image of the displayed object 300. For example, the image acquisition device 405 may be, but not limited to, a camera.
FIG. 4 illustrates an example of the image acquisition device 405, wherein the image acquisition device 405 is arranged to acquire the optical image of the displayed object 300 to be displayed. Specifically, the image acquisition device 405 comprises a photoelectric conversion chip 4051 and a lens module 4052, wherein the lens module 4052 is held in the photosensitive path of the photoelectric conversion chip 4051, such that after the light reflected by the displayed object 300 and passed through the lens module 4052 into the image acquisition device 405, the photoelectric conversion chip 4051 will receive the light in order to perform photoelectric conversion to obtain the optical image regarding the displayed object 300 to be displayed.
It is worth mentioning that the lens module 4052 is constructed to have at least one lens 40520, wherein the number of the lenses 40520 of the lens module 4052 is not limited in the control system 100 of the present invention. For example, the lens module 4052 can be constructed to have a single lens 40520. However, a person who skilled in the art should understand that in other possible examples of the control system 100, the lens module 4052 can be constructed to have two, three, four five, six, seven or more lenses 40520. When the lens module 4052 is constructed to have a single lens 40520, the lens 40520 is preferably a convex lens.
It should be understood that, in some embodiments of the present invention, when there is a single lens 40520, the lens 40520 is configured as an imaging aperture to generate an image of the displayed object 300 through the aperture, or the lens 40520 can be set as an optical spherical mirror. Then, it can be further understood that when two or more lenses 40520 are configured, the lenses 40520 can be configured by a combination of at least one of a convex lens, a concave lens, an optical spherical lens, and an imaging aperture.
Preferably, the lens module 4052 can be driven to move along the photosensitive path of the photoelectric conversion chip 4051 to move at a position relative to the photoelectric conversion chip 4051 in order to adjust a focal length of the image acquisition device 405 for obtaining a better image by the image acquisition device 405. Optionally, the image acquisition device 405 is rotatable, such that the lens module 4052 of the image acquisition device 405 can move to face different directions. For example, when the illuminated object 301 moves in the display environment 302, the image acquisition device 405 can rotate synchronously with the movement of the illuminated object 301 in the display environment 302, such that the image acquisition device 405 can obtain the optical image of the illuminated object 301, i.e. the optical real image thereof, in a real time manner.
As shown in FIG. 1, the control system 100 comprises an information collection unit 10, a processing unit 20, a detection unit 30, an expert database 40, a search unit 50, a scheme generation module 60, and a control unit 70. The processing unit 20 is communicatively connected to the information collection unit 10. The detection unit 30 is communicatively connected to the processing unit 20. The search unit 50 is communicatively connected to the detection unit 30 and the expert database 40. The scheme generation module 60 is communicatively connected to the search unit 50. The control unit 70 is communicatively connected to the scheme generation module 60.
The information collection unit 10 is configured to obtain the optical image of the displayed object 300 via the communicatively connection of the image acquisition device 405. The communication connection method between the information collection unit 10 and the image acquisition device 405 can be a wireless connection or a wired connection. Preferably, the information collection unit 10 is communicatively connected to the image acquisition device 405 in a wireless connection. The image acquisition device 405 is configured to obtain the optical image of the displayed object 300 by photographing the displayed object 300 in a real time manner. Preferably, the information collection unit 10 can be communicatively connected to the photoelectric conversion chip 4051 of the image acquisition device 405 in order to enable the information collection unit 10 to receive the optical image of the displayed object 300 from the photoelectric conversion chip 4051 of the image acquisition device 405.
Furthermore, before using the image acquisition device 405 to acquire the optical image of the displayed object 300, a predetermined type of light can be emitted to the displayed object 300. For example, the color, color temperature, intensity, etc. of the light emitted to the displayed object 300 can be preset in advance as required. After the light is emitted to the displayed object 300 to illuminate the displayed object 300, the image acquisition device 405 can be used to photograph the displayed object 300 to obtain the optical image thereof. A person who skilled in the art should understand that, at this time, the color of the optical image of the displayed object 300 acquired by the image acquisition device 405 is different from the true color of the displayed object 300. The characteristic value of the color of the obtained optical image of the displayed object 300 and the characteristic value of the color of the light emitted to the displayed object 300 can determine the chromaticity of the optical image of the displayed object 300. Through such configuration, the control system 100 can control the status of the light fixture 200 in order to better match the status of the light fixture 200 with the real-time status of the displayed object 300.
The processing unit 20 is configured to receive the optical image of the displayed object 300 from the information collection unit 10, wherein the processing unit 20 is also configured to analyze the optical image of the illuminated object 301 of the displayed object 300 for processing and mixing light to obtain a light group. Specifically, the processing unit 20 further comprises a processing module 21 and a light blending module 22, wherein the light blending module 22 is communicatively connected to the processing module 21. The processing module 21 is communicatively connected to the information collection unit 10. The detection unit 30 is communicatively connected to the light blending module 22.
The processing module 21 is configured to receive the optical image of the displayed object 300 from the information collection unit 10, wherein the processing module 21 is configured to analyze and process the optical image of the displayed object 300 to obtain the optical image of the illuminated object 301 of the displayed object 300. The light blending module 22 is configured to blend and mix the chromaticity of the optical image of the illuminated object 301 to obtain the light group of the illuminated object 301. It is worth mentioning that the light blending mode of the light blending module 22 to the chromaticity of the optical image of the illuminated object 301 should not be limited in the control system 100 of the present invention. For example, in an example of the control system 100 of the present invention, the light blending mode of the light blending module 22 can average all chromaticities or specific chromaticities included in the chromaticity of the optical image of the illuminated object 301 to obtain the light group. For example, the specific chromaticity included in the chromaticity of the optical image of the illuminated object 301 may be the main chromaticity of the illuminated object 301. Specifically, the chromaticity of the optical image of the illuminated object 301 may include the specific chromaticity that can affect the visual effect of the illuminated object 301. In another example of the control system 100 of the present invention, the light blending module 22 may first analyze the optical image of the illuminated object 301 to obtain a RGB combination ratio value of all chromaticities or a RGB value of a specific chromaticity contained in the optical image of the illuminated object 301. Then, the RGB combination ratio values of all the chromaticities or the RGB combination ratio values of the specific chromaticity are averaged to obtain the light group. A person who skilled in the art should understand that RGB in the RGB combination ratio value involved in the present invention is a color mode, that is, the RGB color mode. By providing or determining the RGB combination ratio value, a specific color of chromaticity can be determined. A person who skilled in the art should also understand that in other specific examples of the control system 100 of the present invention, the light blending module 22 may also use other light blending modes. For example, the light blending module 22 may first analyze the optical image of the illuminated object 301 to obtain RGB combined ratio values of all chromaticities contained in the optical image of the illuminated object 301. Then, all the RGB combination ratio values of chromaticities or the RGB combination ratio values of specific chromaticities are mixed in a preset manner to obtain the light group, wherein the preset method can be reduced in half, doubled, reduced by a certain amount, increased by a certain amount, and mapped to other chromaticities based on the RGB values of all chromaticities or the RGB combined ratio of specific chromaticities.
It is worth mentioning that the above mentioned detection method of the present invention for detecting the RGB combination ratio of the chromaticity of the light group related to the illuminated object 301 is merely an example. In another example of the control system 100, it is also possible to directly perform chromaticity detection on the light group related to the illuminated object 301 to determine the type of the light group according to the chromaticity of the light group.
It is worth mentioning that, in another embodiment of the control system 100 of the present invention, the information collecting unit 10 is able to directly obtain the light group of the illuminated object 301 of the displayed object 300. That is, in this example of the control system 100, the control system 100 does not need to capture the optical image of the illuminated object 301 of the displayed object 300 through the image acquisition device 405, and in the subsequent process, the processing unit 20 is configured to analyze the optical image of the illuminated object 301 of the displayed object 300 to obtain the light group of the illuminated object 301 of the displayed object 300. Specifically, in this example of the control system 100 of the present invention, the information collection unit 10 is communicatively connected to at least one color sensor, wherein the color sensor can be, but not limited to, TCS230 categorized sensor. The information collection unit 10 can directly obtain the light group from the illuminated object 301 of the displayed object 300 through the color sensor. The detection unit 30 can be communicatively connected to the information collection unit 10 for enabling the detection unit 30 to directly perform chromaticity detection on the light group obtained by the information collection unit 10 regarding the illuminated object 301 of the displayed object 300. Generally, the image acquisition unit 405 is configured to simultaneously obtain the optical image of the illuminated object 301 of the displayed object 300 and the optical image of the display environment 302, wherein the status of the light fixture 200 is subsequently adjusted depending on the status of the illuminated object 301. Especially, when the display environment 302 is remains unchanged, the adjustment of the status of the light fixture 200 is almost entirely depended on the status of the illuminated object 301. Therefore, after the optical image of the displayed object 300 is acquired by the image acquisition unit 405, the processing module 21 is required to partition the optical image of the illuminated object 301 in the optical image of the displayed object 300 and the optical image of the display environment 302.
Furthermore, the processing module 21 comprises an analysis sub-module 211 and an identification sub-module 212, wherein the identification sub-module 212 is communicatively connected to the analysis sub-module 211.

After receiving the optical image of the displayed object 300 from the information collection unit 10, the analysis sub-module 211 is configured to analyze the optical image of the displayed object 300 to obtain an analysis result. The identification sub-module 212 is configured to identify the optical image of the displayed object 300 according to the analysis result obtained by the analyzing sub-module 211, so as to distinguish between the optical image of the illuminated object 301 and the optical image of the display environment 302 contained in the optical image of the displayed object 300. The light blending module 22 is configured to mix the chromaticity of the optical image of the illuminated object 301 to obtain the light group.
For the displayed object 300 in condition that both the displayed object 301 and the display environment 302 are remain unchanged, after the information collection unit 10 collects the optical image of the displayed object 300 acquired by the image acquisition device 300, the analysis sub-module 211 is configured to analyze the chromaticity change in the optical image of the displayed object 300. The identification sub-module 212 is configured to distinguish the illuminated object 301 and the display environment 302 according to the chromaticity change in the optical image of the displayed object 300 analyzed by the analyzing sub-module 211, such that the optical image of the illuminated object 301 and the optical image of the display environment 302 are distinguished. As shown in FIGS. 5A and 5B as an example of a food market place, a meat product to be sold is embodied as the illuminated object 301, wherein the display environment 302 can be a countertop for placing meat product or a hanging frame for hanging meat product in suspending manner. It can be understood that the meat product as the illuminated object 301 while the countertop and/or the hanging frame as the display environment 302 are remain unchanged, the image acquisition device 405 is configured to simultaneously obtain an optical image of the meat product of the illuminated object 301 and an optical image of the countertop and/or the hanging frame as the display environment 302. Generally, in order to highlight the meat product as the illuminated object 301, the chromaticity of the countertop and/or the hanging frame as the display environment 302 and the chromaticity of the meat product as the illuminated object 301 are so different. Subsequently, after analyzing the chromaticity of the meat product as the illuminated object 301 and the chromaticity of the countertop and/or the hanging frame as the display environment 302 through the analysis sub-module 211, the identification sub-module 212 is configured to distinguish the optical image of the illuminated object 301 from the optical image of the display environment 302 according to the analysis result of the analysis sub-module 211.
For the displayed object 300 in condition that the illuminated object 301 changes while the display environment 302 remains unchanged, after obtaining the optical image of the displayed object 300, the processing module 21 is also configured to distinguish the optical image of the illuminated object 301 and the optical image of the display environment 302 by the difference between the chromaticity of the illuminated object 301 and the chromaticity of the display environment 302. In addition, for another example of the control system 100 of the present invention, the analysis sub-module 211 is configured to analyze at least two optical images of the displayed object 300 to determine a changing portion of the optical image of the displayed object 300, such that, subsequently, the identification sub-module 212 is configured to distinguish the optical image of the illuminated object 301 from the optical image of the display environment 302. It can be understood that after analyzing at least two optical images of the displayed object 300, the changing portion of the optical image of the displaced object 300 is considered as the optical image of the illuminated object 301 while an unchanged portion of the optical image of the displaced object 300 is considered as the optical image of the display environment 302. As shown in FIGS. 6A to 6D as an example of a fashion show walkway, a model is embodied as the illuminated object 301, wherein the walkway is embodied as the display environment 302. It can be understood that the walkway as the display environment 302 remains unchanged, and the model as the illuminated object 301 walks on the walkway. When at least two optical images of the displayed object 300 are obtained at different times, the analysis sub-module 211 is configured to easily obtain the optical image of the displayed object 300 after analyzing these optical images to determine which portion is changing, i.e. the changing portion, and which portion is unchanged, i.e. the unchanged portion. Therefore, the identification sub-module 212 is configured to distinguish the optical image of the illuminated object 301 in the displayed object 300 from the optical image of the display environment 302.
For the displayed object 300 in condition that both the illuminated object 301 and the display environment 302 keep changing, after obtaining the optical image of the displayed object 300, the processing module 21 is configured to distinguish the optical image of the illuminated object 301 and the optical image of the display environment 302 in the optical image of the displayed object 300 through the combination of the chromaticity and the motion. For the stage as an example, after obtaining the optical image of the stage, the processing module 21 is configured to distinguish the optical image of the illuminated object 301 and the optical image of the display environment 302 in the optical image of the displayed object 300 through the combination of the chromaticity and the motion.

For example, the detection unit 30 can perform RGB combination ratio value detection from the light group in order to determine the RGB combination ratio value of the light group. It is worth mentioning that different types of the light groups correspond to different RGB combination ratio values. In addition, it should be understood that there is a corresponding relationship between the RGB combination ratio value of the light group and the chromaticity of the optical image of the illuminated object 301.
It is worth mentioning that the above mentioned detection unit 30 can obtain the detection result by detecting the RGB combination ratio value of the light group as merely an example, wherein it should not be considered as a limitation on the content and scope of the control system 100 of the present invention.

For example, when the illuminated objects 301 at different statuses are placed in the same display environment 302, the type of light and the illumination angle of the light to be provided for the illuminated object 301 are different. At this time, the expert can provide different chromaticities to be output according to the experiences and store them in the memory 402. For another example, for the illuminated object 301 at the same status in different display environments 302, the type of light and the illumination angle of the light to be provided for the illuminated object 301 are different. At this time, the expert can provide different chromaticities to be output according to the experiences and store it in the memory 402.
