The specific implementation manner of the present utility model will be described in more detail below in combination with schematic diagrams. According to the following description and claims, the advantages and features of the utility model will be more clear. It should be noted that all the drawings are in very simplified form and use inaccurate scales, which are only used to facilitate and clearly illustrate the purpose of the embodiment of the present utility model.

FIG. 1 is a schematic block diagram of a first embodiment of a light bar controller of the present invention. As shown in the figure, the light bar controller 100 is connected to an electronic device 200, and the electronic device 200 has a screen to display an image. For example, the electronic device 200 may be a notebook computer, a tablet computer, a host computer (with a screen), a smart TV, a smart phone, and other electronic devices capable of image processing.

The light bar controller 100 has a connector 120 , four light bar connectors 130 , a processing unit 110 , a light source module 140 and a power supply module 150 . Wherein, the connector 120 is used to connect the aforementioned electronic device 200 and receive a segmental color scale data S1 of an image displayed on the screen of the electronic device 200 . The connector 120 can be a universal serial port (USB) or a data transmission port commonly used in other electronic devices. The partitioned color scale data S1 will be described in more detail in the following paragraphs.

The light bar connector 130 is used to connect the light bar and provide the electric energy required for the light bar to emit light. In one embodiment, users can choose addressable LED light strips or colored LED light strips to provide more variety of lighting effects.

Also, please refer to FIG. 2 , in one embodiment, the light bar controller 100 of this embodiment has four light bar connectors 130 to connect and support up to four light bar 300a, 300b, 300c, 300d, respectively It is installed and fixed (for example, by sticking or magnetically) around the back of the screen of the electronic device 200 to present a light and shadow effect corresponding to the screen image. However, the present invention is not limited thereto. According to actual usage requirements, these light bars can be installed on other positions of the electronic device 200, such as the edge of the screen, or other objects other than the electronic device 200, such as walls or other devices.

In addition, although the light bar controller 100 of the present invention has four light bar connectors 130 to support up to four light bar, the present invention is not limited thereto. According to actual needs, the computing capability of the light bar controller 100 itself, and the power supply limit of the power supply module 150 (for example: the upper limit of the driving current that can be provided, etc.), the light bar controller 100 of the present invention can also be equipped with one or are other different numbers of light bar connectors 130 .

The processing unit 110 is electrically connected to the connector 120 and the light bar connector 130, and generates a light bar control signal S2 according to the partition color scale data S1 received from the connector 120, and outputs it to each light bar connector 130 to control the connected lights. The glow mode of the light bar. Specifically, the processing unit 110 will confirm the position of each light-emitting component on the connected light bar 300a, 300b, 300c, 300d, and control the light-emitting mode of the corresponding light-emitting component according to the partition color scale data S1, such as brightness, color temperature, color Wait. For example, the processing unit 110 can sequentially number the light-emitting components on the light bar, and control the corresponding light-emitting components according to the color-level data corresponding to each number (that is, the position of the light-emitting component) in the partition color-level data S1. glow mode. For example, the light-emitting component on the light bar is used to extend the light and shadow effect of the screen image outward, or the light-emitting component on the light bar is used to adjust the white balance of the screen image.

The light source module 140 is used to generate a bright source to remind the user whether the light bar controller 100 has been connected to the electronic device 200 or has received zonal color scale data. Further, the processing unit 110 is electrically connected to the light source module 140 to generate a light source control signal S3 to control the light source module 140 . When the processing unit 110 does not receive the sub-area color scale data S1, or the processing unit 110 detects that the connector 120 is not connected to the electronic device 200, the processing unit starts up according to a default lighting mode (such as blinking, always on, etc.) The light source module 140 .

It should be noted that although the light bar controller 100 of this embodiment has a light source module 140 to generate bright light as a reminder to the user of the state of the light bar controller 100 . However, the present invention is not limited thereto. In another embodiment, the light source module 140 may also be omitted to reduce manufacturing costs.

The power supply module 150 is used to supply the electric energy required by the light bar to emit light. For example, the power supply module can be connected to the mains and convert it into DC power for driving the light strip. Moreover, as far as a preferred embodiment is concerned, in addition to supplying the electric energy required by the light bar, the power supply module can also supply other electronic components in the light bar controller 100, such as the processing unit 110, the light source module 140, etc., so required power.

FIG. 3 is a screen shot illustrating a first embodiment of the partitioned color scale data of the present invention. As shown in the figure, the screen image 500 is presented on the screen and extends to cover the entire screen. The aforesaid sub-level gradation data S1 corresponds to the surrounding area 520 of the screen image 500 of the electronic device. Moreover, the number of partitions of the partitioned color scale data S1 is determined according to the number of light-emitting components of the light bar or the distance between the light-emitting components. The surrounding area 520 surrounds the screen image 500 and has a predetermined width w. As far as a preferred embodiment is concerned, in order to avoid delays in computing time caused by too large surrounding area 520 , and even affect the normal operation of the electronic device 200 , the preset width w may be 15-25 image pixels.

It should be noted that the sectional color scale data S1 is generated by the electronic device 200 instead of the processing unit 110 in the light bar controller 100 . Therefore, the zonal color scale data S1 is not limited by the computing capability and instruction cycle of the light bar controller 100 , and more real-time and more accurate zonal color scale data S1 can be generated.

Secondly, in order to make the sub-level color scale data S1 accurately reflect the color scale or color of the screen image 500 . As far as a preferred embodiment is concerned, the sectional color scale data S1 may be the average color scale value of the image pixels in each sub-area 522, or the color with the largest area (the largest number of image pixels) in each sub-area 522. order value. However, the present invention is not limited thereto. Other calculation methods for image processing that can obtain representative color levels or colors from a certain area of the screen image are also applicable to the present invention.

In addition, the processing unit 110 can directly use the partition color scale data S1 to generate the light bar control signal S2 , so that the light emitting brightness of the light emitting components on the light bar corresponds to the color scale of each corresponding sub-area 522 . However, the present invention is not limited thereto. The processing unit 110 can also use the partition color scale data S1 to generate the light bar control signal S2 according to a default mode, for example, use the light bar control signal S2 to adjust the color temperature of the light-emitting components on the light bar.

Since most of the light-emitting components on the light bars 300a, 300b, 300c, and 300d are equidistantly arranged, each side of the surrounding area 520 will be divided into multiple parts according to the number of light-emitting components on the corresponding light bar or the distance between the light-emitting components. sub-region 522. That is to say, the surrounding areas corresponding to the upper side, the lower side, the left side and the right side of the screen image 500 are all divided into a plurality of sub-areas. In the figure, the upper side of the screen image 500 is taken as an example to divide 10 sub-regions 522 .

For example, if it is divided according to the number of light-emitting components, assuming that the number of light-emitting components on the light bar is 10, for a 1920*1080 screen image of 500, the direction of the wide side (that is, the direction of 1920 image pixels) will be divided into There are 10 sub-regions 522, and the length of each sub-region 522 is 192 image pixels. If it is divided according to the pitch of the light-emitting components, assuming that the pitch of the light-emitting components on the light bar is 50mm, and the width of the screen image 500 is 500mm, as far as a 1920*1080 screen image 500 is concerned, the width direction (that is, the direction of 1920 image pixels) ) will be divided into 10 sub-regions 522, and the length of each sub-region 522 is 192 image pixels.

The aforementioned example illustrates the technical content of the present invention by dividing the screen image 500 in the direction of the width. The narrow side direction of the screen image 500 can also be applied in the same way to generate the corresponding sub-level color scale data S1 , so details are not repeated here.

FIG. 4 is a screen shot illustrating a second embodiment of the partitioned color scale data of the present invention. The screen image 600 is presented on the screen. Compared with the embodiment in FIG. 3 , where the screen image 500 extends to cover the entire screen image, the upper and lower sides of the screen image 600 in this embodiment have black bars (black bars) 610 (only the black bar at the top is marked in the figure). side). Screen black borders 610 usually appear when the aspect ratio of the screen is different from the aspect ratio of the video. For example, if the aspect ratio of the screen is 16:10 and the aspect ratio of the image is 16:9, black borders 610 will be generated on the upper and lower sides of the screen image 600; if the aspect ratio of the screen is 16:10 , the aspect ratio of the image is 4:3, and there will be black bars on the left and right sides of the screen.

In this embodiment, when the sub-level color scale data S1 is generated, it does not directly process the presentation content of the entire screen, but the screen image 600 presented on the screen (which can also be understood as the image or audio-visual data presented on the screen) ) for processing. That is to say, in this embodiment, the black border 612 is excluded, and only the screen image 600 is processed, and the sub-level tone data S1 corresponds to the surrounding area 620 of the screen image 600 instead of the surrounding area of the entire screen image. The surrounding area 620 surrounds the screen image 600 and has a predetermined width w.

Further, each side of the surrounding area 620 is divided into a plurality of sub-areas 622 according to the number of light-emitting elements or the spacing of the light-emitting elements on the corresponding light bar. The technical features of this part are similar to the above-mentioned embodiment in FIG. 3 , and will not be repeated here.

It should be noted that, in the aforementioned embodiments of FIG. 3 and FIG. 4 , the partitioned color scale data S1 will cover all the surrounding areas 520,620, that is, the partition calculation will be performed on the surrounding areas 520,620 around the screen image 500,600 to obtain Each sub-area 522, 622 corresponds to the partition color scale value. However, the present invention is not limited thereto. According to the actual needs and the number or length of the matched light bars, the partitioned color scale data S1 can also only target part of the surrounding area 520,620, for example: only for the upper side of the screen image 500,600, or only for the left side of the screen image 500,600 half.

FIG. 5 is a schematic block diagram of a second embodiment of the light bar controller of the present invention. The light bar controller 100' of this embodiment is similar to the light bar controller 100 shown in FIG. . The processing unit 110 is electrically connected to the light detector 160, and adjusts the light bar control signal S2 according to the detected ambient brightness data S4.

For example, if the ambient brightness data S4 received by the processing unit 110 shows that the light bar controller 100' is in a high-brightness environment, the processing unit 110 then appropriately increases the brightness of the light-emitting components on the light bar according to the ambient brightness data S4; Conversely, if the ambient brightness data S4 received by the processing unit 110 indicates that the light bar controller 100 ′ is in a low-brightness environment, the processing unit 110 then moderately lowers the brightness of the light-emitting components on the light bar according to the ambient brightness data S4 .

FIG. 6 is a schematic cross-sectional view of an embodiment of the component configuration of the light bar controller 100 of the present invention. The component configuration in the figure corresponds to the embodiment in FIG. 1 . As shown in the figure, the light bar controller 100 has a circuit board 102 and a housing 104, the processing unit 110 and the light source module 140 are arranged on both sides of the circuit board 102, the connector 120, the light bar connector 130 and The processing unit 110 is disposed on the same side of the circuit board 102 . The casing 104 is used to protect the internal components of the light bar controller 100 , and forms an opening corresponding to the light projecting direction of the light source module 140 to generate a luminous pattern. Moreover, for a preferred embodiment, the light source module 140 has a plurality of light emitting components 142, and these light emitting components 142 are arranged on the circuit board 102 according to the patterns of the light emitting patterns.

To sum up, the light bar controller of the present invention can effectively control the light-emitting mode (such as brightness, color temperature, etc.) The computing power and instruction cycle of the light strip controller itself are limited. Therefore, the light bar controller of the present utility model can provide richer light and shadow changes, and with the presentation of the screen image, the light bar controller of the present utility model can also extend the light and shadow effect of the screen image, providing users with more abundant Visual effects.

The above are only preferred embodiments of the utility model, and do not limit the utility model in any way. Anyone skilled in the technical field, without departing from the scope of the technical means of the utility model, makes any form of equivalent replacement or modification to the technical means and technical content disclosed in the utility model, which is not deviating from the utility model.
