Description

Technical Field

[0001] The utility model relates to the technical field of LED light bars, in particular to an LED light bar with a high color gamut backlight module. Background Art

[0002] An LED light bar with a high color gamut backlight module uses a wide color gamut LED chip and an optimized light guide plate to present richer and more saturated colors. It also has a partitioned backlight control function, which realizes independent adjustment of brightness and color temperature through a multi-channel LED driver chip and an optical sensor, improving local contrast and HDR display effects. In addition, the light bar also supports sound synchronization backlight. Through an audio signal processing chip and a sound and light synchronization control circuit, it realizes real-time synchronization of backlight brightness, color and music rhythm, creating an immersive audio-visual experience. The existing backlight module with a pull-out LED light bar (publication number: CN204945572U) has the following disadvantages and needs further improvement.

[0003] 1. The LED chips used in traditional devices have a narrow color gamut, especially in the red and green bands, which makes the display unable to present true and rich colors. Due to insufficient color gamut coverage, traditional devices will have problems such as color cast and color difference when restoring the colors of the real world, affecting the accuracy and consistency of colors. The LED chips and light guide plate designs of traditional devices may not provide high enough brightness and contrast, resulting in poor display effects. Therefore, there is an urgent need for an LED light bar with a high color gamut backlight design.

[0004] 2. Traditional devices use global backlight control and cannot independently adjust different areas according to the image content. As a result, when displaying high-contrast images, the contrast between bright and dark areas cannot be effectively improved, and the overall picture performance is poor. Due to the lack of partitioned backlight control, traditional devices cannot achieve true local dimming, resulting in limited HDR display effects and difficulty in presenting real and dynamic images. The global backlight control of traditional devices may cause inconsistent brightness performance in different areas of the screen, especially when displaying large dark scenes, the brightness distribution of the picture may be uneven. The device lacks real-time backlight brightness acquisition and feedback control mechanism, and cannot be dynamically optimized according to ambient lighting conditions and image content, resulting in limited room for display quality improvement. Therefore, there is an urgent need for an LED light bar with a partitioned backlight design.

[0005] 3. Traditional devices cannot synchronize audio signals with backlight changes, resulting in the inability to achieve the best coordination between visual and auditory experience. Due to the lack of this function, traditional devices cannot enhance the emotional expression and rendering power of music through backlight changes. Traditional devices cannot provide this real-time interactive experience and appear relatively static and monotonous. For users who pursue high-quality audio and video entertainment experience, such as music lovers and game players, traditional devices cannot enhance the immersion of music and games through sound and light synchronization effects, and may not meet their entertainment needs. Therefore, there is an urgent need for an LED light bar with sound synchronization design. Utility Model Content

[0006] The main purpose of the utility model is to provide an LED light bar with a high color gamut backlight module, which can effectively solve the problems in the background technology.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: there is an LED light strip with a high color gamut backlight module, an LED light strip is installed above the main body, a wide color gamut LED chip is installed inside the LED light strip, a light guide plate is installed inside the LED light strip, a multi-channel driving chip is installed inside the LED light strip, an optical sensor is installed inside the LED light strip, an audio signal processing chip is installed inside the LED light strip, a sound and light synchronization control circuit is installed inside the LED light strip, an integrated module is installed inside the LED light strip, and a base plate is installed inside the LED light strip.

[0008] Preferably, the exterior of the main body adopts a rounded corner design.

[0009] Preferably, the multi-channel driving chip has a plurality of small holes inside.

[0010] Preferably, there are several modules above the sound and light synchronization control circuit.

[0011] Preferably, a buckle is installed above the integrated module.

[0012] Preferably, the LED light strip is fixed to the main body by bolts.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model can cover a wider color gamut by adding wide color gamut LED chips and light guide plates, especially with better performance in the red and green bands, so that the display can present more realistic, rich and saturated colors. It improves the accuracy and consistency of colors, reduces color cast and color difference problems, and can restore color effects closer to the real world. At the same time, the optimized light guide plate can more effectively distribute the brightness of the LED light source evenly, provide higher brightness and contrast, and thus bring better overall display effects.

[0015] 2. The utility model realizes partitioned backlight control and real-time feedback adjustment by adding multi-channel driver chips and optical sensors, which brings significant improvements. Through the multi-channel driver chip, the device can independently adjust different areas according to the image content. When displaying high-contrast images, it can effectively improve the contrast between bright and dark areas, making the overall picture performance more outstanding. At the same time, partitioned backlight control can also achieve true local dimming, greatly improving the HDR display effect and presenting a more realistic and dynamic picture. The addition of optical sensors provides a real-time backlight brightness acquisition and feedback control mechanism, which can be dynamically optimized according to ambient lighting conditions and image content, solving the problems of inconsistent brightness performance in different areas of the screen of traditional devices and uneven picture brightness distribution, and further improving the display quality.

[0016] 3. The utility model can achieve real-time synchronization of sound and backlight by adding an audio signal processing chip and a sound-light synchronization control circuit, which brings significant improvement. Through the audio signal processing chip, the device can analyze the audio signal in real time, extract characteristics such as rhythm and intensity, and pass this information to the sound-light synchronization control circuit. The control circuit adjusts the brightness, color and other parameters of the backlight in real time according to the audio characteristics, so that the backlight changes are perfectly synchronized with the rhythm of the music and emotional expression. This sound-light synchronization effect greatly enhances the emotional rendering power of music and brings users a more vivid, dynamic and expressive audio-visual experience. For music lovers, game players and other users who pursue high-quality audio and video entertainment, the sound-light synchronization function provided by the LED light bar can significantly enhance the immersion of music and games, create a more immersive entertainment atmosphere, and meet their needs for high-quality audio and video experience.

[0024] Example

[0025] See also Figure 1-3 , the utility model provides a technical solution:

[0026] An LED light strip with a high color gamut backlight module, wherein an LED light strip 2 is installed above the main body 1, a wide color gamut LED chip 3 is installed inside the LED light strip 2, a light guide plate 4 is installed inside the LED light strip 2, a multi-channel driving chip 5 is installed inside the LED light strip 2, an optical sensor 6 is installed inside the LED light strip 2, an audio signal processing chip 7 is installed inside the LED light strip 2, a sound and light synchronization control circuit 8 is installed inside the LED light strip 2, an integrated module 9 is installed inside the LED light strip 2, and a base plate 10 is installed inside the LED light strip 2.

[0027] The LED light bar of the utility model realizes functions such as high color gamut display, partitioned backlight control, and sound and light synchronization through the coordinated work of various components. First, the wide color gamut LED chip serves as a light source, emitting light with a wider color gamut coverage and better color performance. These lights are evenly distributed through the light guide plate, providing higher brightness and contrast. The light guide plate optimizes the distribution of light, reduces light loss, and improves the display effect. The multi-channel driver chip independently controls the LEDs in different areas to achieve partitioned backlight adjustment. The optical sensor collects backlight brightness information in real time and feeds it back to the driver chip to form a closed-loop control. Through this partition control and real-time feedback, the device can dynamically optimize the brightness and contrast of different areas according to the image content and ambient lighting conditions, bringing a more realistic and vivid HDR display effect.

[0028] Secondly, the audio signal processing chip performs real-time analysis on the input audio signal to extract characteristic information such as music rhythm and intensity. The sound and light synchronization control circuit receives this characteristic information and converts it into a backlight control signal. The control circuit adjusts the brightness, color and other parameters of the LED in real time to synchronize the backlight changes with the music rhythm and emotional expression. Through this sound and light synchronization technology, the device can dynamically present a matching backlight effect according to the rhythm, melody, emotional ups and downs of the music, creating an immersive audio-visual experience.

[0029] Finally, the integrated module integrates the various components together to provide a compact and reliable system solution. The base plate provides mounting support for the various components to ensure the stability of the structure. The LED light strip integrates various functional components, including wide color gamut LED chips, light guide plates, multi-channel driver chips, optical sensors, audio signal processing chips, and sound and light synchronization control circuits, etc., to achieve modular integration of functions. The main body provides an external frame to protect and support the internal LED light strip and other components. Through this modular and integrated design, the LED light strip achieves a highly integrated and compact structural layout, and at the same time has multiple functions such as high color gamut display, partitioned backlight control, sound and light synchronization, representing a comprehensive innovation in LED backlight technology.
