Description

Technical Field

[0001] This invention relates to the field of lighting technology, and in particular to an image display device with an ambient light strip assembly and the light strip assembly. Background Technology

[0002] In daily life, people often watch televisions, monitors, and other image display devices in dark environments to simulate a movie theater experience. However, compared to the large-area illumination of a giant movie screen, the strong light emitted by an image display device can create a stark contrast with the surrounding dim environment, causing eye strain and affecting eyesight. Furthermore, the light emitted by the image display device alone is insufficient to create ambiance, resulting in a poor overall visual effect. To address this, existing technologies have developed the use of LED strips installed behind the image display device or on a background wall opposite it as ambient lighting. The color and brightness of these ambient lights change according to the brightness and color of the light emitted by the image display device, reducing the strong contrast with the ambient light while better creating ambiance based on the content being played, thus improving the visual experience.

[0003] However, please see Figure 1 These light strips are usually arranged in a parallel or perpendicular manner. They can easily block each other in the corners of the image display device, resulting in insufficient or uneven brightness in the corners and dark areas, which affects the overall visual effect. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide an image display device with an ambient light strip assembly to reduce dark areas that occur when using ambient lights.

[0005] The technical solution adopted in this invention is as follows:

[0006] An image display device with an ambient light strip assembly includes an image display device having a back panel and a light strip assembly. The light strip assembly is mounted on the back panel and emits light to the outside of the image display device. The light strip assembly includes a first light group, a second light group, a first corner light group, and a second corner light group. Projected along a direction perpendicular to the back panel surface, the first light group is close to and arranged along a first edge of the back panel, and the second light group is close to and arranged along a second edge of the back panel, the first edge intersecting the second edge. The first corner light group and the second corner light group are located at the first light group and the second light group respectively. The groups are symmetrical about a straight line passing through the intersection of the first edge and the second edge; the first corner light group includes two or more supplementary light beads, one of which is close to the second corner light group, and the remaining supplementary light beads are arranged sequentially towards the first edge. The vertical distance from the supplementary light bead close to the second corner light group to the first edge is greater than the vertical distance from the supplementary light bead away from the second corner light group to the first edge. The light emission angle of the supplementary light bead close to the second corner light group relative to the back panel is greater than the light emission angle of the supplementary light bead away from the second corner light group relative to the back panel.

[0007] Compared with the prior art, the image display device with ambient light strip assembly of the present invention provides supplementary lighting to the corners of the image display device through multiple supplementary light beads with different light emission angles, reduces the dark areas generated when the ambient light is used, improves the overall visual effect of the ambient light, and provides uniform light to the environment in which the image display device is located, thus protecting eyesight.

[0008] Furthermore, the first corner light group and the second corner light group are symmetrically arranged with the angle bisector passing through the intersection of the first edge and the second edge and bisecting the angle between the first edge and the second edge, so as to improve the uniformity of the ambient light.

[0009] Furthermore, the number of supplementary lighting LEDs is 4. Setting an appropriate number of supplementary lighting LEDs can achieve a better supplementary lighting effect while saving costs.

[0010] Furthermore, in the first corner light group, starting from the side closest to the second corner light group, the light emission angle of the supplementary light beads relative to the back panel surface is successively 70°, 55°, 40°, 30° or 60°, 50°, 35°, 20°, so as to reasonably control the illumination range.

[0011] Furthermore, the distance between two adjacent supplementary light LEDs is 3mm to 10mm to reduce light mixing and crosstalk.

[0012] Furthermore, the supplementary light beads are arranged in a straight line, and the angle between the straight line and the first edge is 15° to 45° to ensure the supplementary lighting effect.

[0013] Furthermore, the first edge and the second edge are perpendicular to each other to accommodate existing image display devices.

[0014] Furthermore, the first corner light assembly also includes a lens housing, on which a lens corresponding to each supplementary light bulb is provided to diffuse the light from the supplementary light bulb and form the desired light spot shape.

[0015] Furthermore, the first corner light assembly also includes a substrate electrically connected to the supplementary light bulb. The lens housing is provided with a lens housing foot, which is inserted into the substrate and its length is greater than or equal to the thickness of the substrate, so as to stabilize the installation of the lens housing relative to the supplementary light bulb and prevent the lens housing from falling off.

[0016] Furthermore, this invention also provides a light strip assembly to reduce dark areas that appear when using ambient lighting. The technical solution is as follows:

[0017] A light strip assembly includes a mounting plate, a first light group, a second light group, a first corner light group, and a second corner light group. The mounting plate has intersecting first and second edges. Projected along a direction perpendicular to the surface of the mounting plate, the first light group is close to and arranged along the first edge, and the second light group is close to and arranged along the second edge. The first and second corner light groups are located between the first and second light groups and are symmetrical about a straight line passing through the intersection of the first and second edges. The first corner light group includes two or more supplementary light beads, one of which is close to the second corner light group, and the remaining supplementary light beads are arranged sequentially towards the first edge. The vertical distance from the supplementary light bead close to the second corner light group to the first edge is greater than the vertical distance from the supplementary light bead away from the second corner light group to the first edge, and the light emission angle of the supplementary light bead close to the second corner light group relative to the surface of the mounting plate is greater than the light emission angle of the supplementary light bead away from the second corner light group relative to the surface of the mounting plate.

[0018] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

[0031] Please see Figure 2 The present invention discloses an image display device with an ambient light strip assembly, comprising an image display device (not labeled) and a light strip assembly 20. The image display device has a back plate 10 opposite to the screen. The back plate 10 serves as a mounting plate, and the light strip assembly 20 is mounted on the back plate 10 and emits light to the outside of the image display device.

[0032] In this embodiment, the back panel 10 includes a first edge 11, a second edge 12, and a plurality of through holes 13 formed on its surface. Projected along a direction perpendicular to the surface of the back panel 10, the first edge 11 and the second edge 12 intersect at intersection point A, forming a first included angle α. In this embodiment, projected along a direction perpendicular to the surface of the back panel 10, the back panel 10 is rectangular, and the first edge 11 and the second edge 12 are the long side and the short side of the intersecting back panel 10, respectively. Preferably, the first edge A extends horizontally, the second edge B extends vertically, and the first included angle α is 90°. The LED strip assembly 20 is embedded from inside the image display device into the through holes 13 and faces outward, thereby being fixed to the back panel 10.

[0033] Please refer to the following: Figures 3 to 5 The light strip assembly 20 includes a first light group 21, a second light group 22, a first corner light group 23, and a second corner light group 24. Projected along a direction perpendicular to the surface of the back panel 10, the first light group 21 and the second light group 22 are respectively close to the first edge 11 and the second edge 12, and their light is emitted towards the first edge 11 and the second edge 12, respectively. The first light group 21 includes a plurality of LED beads 211 arranged sequentially along the first edge 11 and towards the second edge 12. The second light group 22 includes a plurality of LED beads 221 arranged sequentially along the second edge 12 and towards the first edge 11. In this embodiment, the first light group 21 is a single group, extending along the edge directly above the back panel 10; the second light group 22 is a double group, located on the left and right sides of the first light group 21, respectively. It should be noted that, in this invention, "arranged along the first edge 11 and the second edge 12" refers to the overall arrangement direction of the LED beads in the first light group 21 and the second light group 22, but it does not require that each LED bead must be on the same straight line and arranged in a single row. As needed, each LED bead 211 or each LED bead 212 can be arranged in a wavy line, a curve, or other arrangement, such as multiple rows, staggered front and back, or multiple rows of curves.

[0034] The first corner light group 23 and the second corner light group 24 are located between the first light group 21 and the second light group 22, and are close to the intersection point A. The first corner light group 23 and the second corner light group 24 are symmetrically arranged along a straight line passing through the intersection point A, with one side close to each other. The other side of the first corner light group 23 is close to the first edge 11, and the other side of the second corner light group 24 is close to the second edge 12. Both emit light towards the intersection point D. In this embodiment, the first corner light group 23 and the second corner light group 24 are symmetrically arranged along the angle bisector C passing through the intersection point A and the first included angle α.

[0035] The first corner light group 23 includes a substrate 231, two or more supplementary light beads 232, and a lens housing 233. The supplementary light beads 232 are arranged along line B and inserted into and electrically connected to the substrate 231. The vertical distance from the supplementary light beads 232 closer to the second corner light group 24 to the first edge 11 is greater than the vertical distance from the supplementary light beads 232 farther from the second corner light group 24 to the first edge 11, such that the second included angle β between line B and the first edge 11 is less than 90°. In this embodiment, the second included angle β is between 15° and 45°. Preferably, the second included angle β is 30°. The lens housing 233 covers the supplementary light beads 232 to diffuse light. The light emitted by each supplementary light bulb 232 has a different tilt angle γ relative to the back plate 10. The supplementary light bulb 232A, which is closer to the second corner light group 24, has the largest tilt angle γ, and the tilt angle γ of the remaining supplementary light bulbs 232 decreases sequentially, with the supplementary light bulb 232D, which is closer to the first edge 11, having the smallest tilt angle γ. The second corner light group 24 has the same structure as the first corner light group 23, and includes a substrate, two or more supplementary light bulbs, and a lens housing. The supplementary light bulbs of the second corner light group 24 are arranged from the side closer to the first corner light group 23 toward the second edge 22, and the substrate, supplementary light bulbs, and lens housing of the second corner light group 24 are symmetrically arranged with respect to the substrate, supplementary light bulbs, and lens housing of the first corner light group 23 along the angle bisector C. The structure of the second corner light group 24 will not be described again here.

[0036] This invention sets different emission angles of the supplementary light beads according to their distance from the outer edge of the back panel 10, providing supplementary lighting to corners prone to darkness from different angles, thus solving the problem of dark corners. The light emitted by the supplementary light beads 232 of the first corner light group 23 and the second corner light group 24 changes in a certain sequence, with each supplementary light bead controlling the color of a specific area, achieving a layered display effect. In this embodiment, please refer to... Figure 6The number of supplementary light beads 232 is four. Starting from the side closest to the second corner light group 24, the supplementary light beads 232 are designated as first supplementary light bead 232A, second supplementary light bead 232B, third supplementary light bead 232C, and fourth supplementary light bead 232D. The angle γ of their emitted light relative to the surface of the back panel 10 is successively 70°, 55°, 40°, 30° or 60°, 50°, 35°, 20°. Testing showed that this arrangement provides the optimal light range and is economical and reasonable. Correspondingly, since the first corner light group 23 and the second corner light group 24 are symmetrically arranged, the angle γ of the emitted light of the supplementary light beads in the second corner light group 24 relative to the surface of the back panel 10, starting from the side closest to the first corner light group 23, is also successively 70°, 55°, 40°, 30° or 60°, 50°, 35°, 20°. Please refer to [link / reference]. Figure 7 The center distance L between two adjacent supplementary light bulbs 232 is 3mm or more. Preferably, the distance between two adjacent supplementary light bulbs 232 is 3 to 10mm to reduce crosstalk between the supplementary light bulbs. Furthermore, in this embodiment, the substrate 231 is an integral structure with the substrate of the first lamp group 21 and / or the second lamp group 22. However, as needed, the substrates of the first lamp group 21, the second lamp group 22, the first corner lamp group 23, and the second corner lamp group 24 can also be set as independent structures. The bulbs of the first lamp group 21, the second lamp group 22, the first corner lamp group 23, and the second corner lamp group 24 can also be LED bulbs, which are energy-saving and environmentally friendly.

[0037] The lens housing 233 is provided with lenses 234 corresponding to each of the supplementary light beads 232. In this embodiment, the lens housing 233 of the multiple supplementary light beads 232 is an integral structure, and is provided with multiple lenses 234, which are respectively located above each supplementary light bead 232, and respectively diffuse the light emitted by the corresponding supplementary light bead 232. The integral structure of the lens housing 233 can improve the installation efficiency, but each supplementary light bead 232 can also be provided with a separate lens housing 233 as needed. Preferably, the crosstalk of the light emitted by each supplementary light bead 232 is reduced by the light structure in the prior art, and a square light spot is formed. The lens housing 233 is provided with lens housing feet 2331 for insertion into the substrate 231. The length of the lens housing feet 2331 is greater than or equal to the thickness of the substrate 231, so as to increase the contact area between the lens housing feet 2331 and the substrate 231 and prevent the lens housing feet 2331 from falling off the substrate 231.

[0038] In addition, the light strip assembly 20 can also be installed separately on a mounting plate similar to the back plate 10, and then installed on a background wall or other position opposite to the image display device to form an ambient light independent of the image display device, thereby reducing maintenance costs and difficulties.

[0039] from Figure 8 (a) and Figure 8 The test results in (b) show that, compared with the prior art, the use of the display device with ambient light strip assembly and light strip assembly of the present invention significantly reduces corner dark areas, provides uniform illumination, enhances brightness, and reduces crosstalk. Furthermore, the supplementary lighting beads are reasonably arranged, resulting in low cost, convenient installation, and stability.

[0040] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
