Abstract

An image display device with an ambient light strip assembly includes a back plate and a light strip assembly. The light strip assembly includes a first light group disposed horizontally, a second light group disposed vertically, a first corner light group, and a second corner light group. The first corner light group and the second corner light group are located between the first light group and the second light group. The first corner light group includes more than two auxiliary light beads. One auxiliary light bead is adjacent to the second corner light group, the remaining auxiliary light beads are arranged in sequence toward the first edge, the vertical distance between the auxiliary light bead adjacent to the second corner light group and the first edge is greater than the vertical distance between the auxiliary light bead on the other side and the first edge.

First claim

What is claimed is:

1. An image display device with an ambient light strip assembly, comprising a light strip assembly and a back plate, wherein
the light strip assembly is mounted on the back plate and emits light to an outer side of the image display device;
the light strip assembly comprises a first light group, a second light group, a first corner light group, and a second corner light group;
along a direction perpendicular to a plate surface of the back plate, a projection of the first light group is adjacent to and arranged along a first edge of the back plate, a projection of the second light group is adjacent to and arranged along a second edge of the back plate, and the first edge intersects with the second edge;
the first corner light group and the second corner light group are located between the first light group and the second light group and are symmetrical about a straight line passing through a point of intersection of the first edge and the second edge; and
the first corner light group comprises more than two auxiliary light beads, an auxiliary light bead of the more than two auxiliary light beads is adjacent to the second corner light group, remaining auxiliary light beads of the more than two auxiliary light beads are arranged in sequence toward the first edge, a vertical distance between the auxiliary light bead adjacent to the second corner light group and the first edge is greater than a vertical distance between an auxiliary light bead of the more than two auxiliary light beads facing away from the second corner light group and the first edge, and an angle of inclination of light emitted by the auxiliary light bead adjacent to the second corner light group relative to the plate surface of the back plate is greater than an angle of inclination of light emitted by the auxiliary light bead facing away from the second corner light group relative to the plate surface of the back plate.

2. The image display device with an ambient light strip assembly of claim 1 , wherein the first corner light group and the second corner light group are symmetrical about an angle bisector passing through the point of intersection of the first edge and the second edge and bisecting an included angle between the first edge and the second edge.

3. The image display device with an ambient light strip assembly of claim 1 , wherein four auxiliary light beads are provided.

4. The image display device with an ambient light strip assembly of claim 3 , wherein in the first corner light group, starting from a side adjacent to the second corner light group, angles of inclination of light emitted by the four auxiliary light beads relative to the plate surface of the back plate are 70°, 55°, 40°, and 30°, respectively, or are 60°, 50°, 35°, and 20°, respectively.

5. The image display device with an ambient light strip assembly of claim 3 , wherein a distance between two adjacent ones of the four auxiliary light beads is 3 mm to 10 mm.

6. The image display device with an ambient light strip assembly of claim 1 , wherein the more than two auxiliary light beads are arranged along a straight line, wherein an included angle between the straight line and the first edge is 15° to 45°.

7. The image display device with an ambient light strip assembly of claim 1 , wherein the first edge is perpendicular to the second edge.

8. The image display device with an ambient light strip assembly of claim 1 , wherein the first corner light group further comprises a lens housing provided with lenses corresponding to the more than two auxiliary light beads.

9. The image display device with an ambient light strip assembly of claim 8 , wherein the first corner light group further comprises a substrate electrically connected to the more than two auxiliary light beads, the lens housing is provided with a lens housing pin inserted into the substrate, and a length of the lens housing pin is greater than or equal to a thickness of the substrate.

10. A light strip assembly, comprising a mounting plate, a first light group, a second light group, a first corner light group, and a second corner light group, wherein
the mounting plate is provided with a first edge and a second edge intersecting with each other;
along a direction perpendicular to a plate surface of the mounting plate, a projection of the first light group is adjacent to and arranged along the first edge, and a projection of the second light group is adjacent to and arranged along the second edge;
the first corner light group and the second corner light group are located between the first light group and the second light group and are symmetrical about a straight line passing through a point of intersection of the first edge and the second edge; and
the first corner light group comprises more than two auxiliary light beads, an auxiliary light bead of the more than two auxiliary light beads is adjacent to the second corner light group, remaining auxiliary light beads of the more than two auxiliary light beads are arranged in sequence toward the first edge, a vertical distance between the auxiliary light bead adjacent to the second corner light group and the first edge is greater than a vertical distance between an auxiliary light bead of the more than two auxiliary light beads facing away from the second corner light group and the first edge, and an angle of inclination of light emitted by the auxiliary light bead adjacent to the second corner light group relative to the plate surface of the mounting plate is greater than an angle of inclination of light emitted by the auxiliary light bead facing away from the second corner light group relative to the plate surface of the mounting plate.
