Flexible light strip

Abstract

This invention discloses a flexible light strip, including a lamp tube and a light strip. The lamp tube extends in a direction and includes two opposing sidewalls, a bottom wall, and a top wall. The two sidewalls, bottom wall, and top wall form a cavity. The two sidewalls and bottom wall are made of opaque material, and the top wall is made of translucent material. The light strip is disposed inside the lamp tube and has a flexible substrate and multiple light-emitting elements. The multiple light-emitting elements are disposed on the flexible substrate and arranged at intervals along the direction. The angle between the light-emitting surface of each light-emitting element and the top wall is 0 to 90 degrees, and the distance between each light-emitting element and the inner wall surface of the lamp tube ranges from 0.5 to 5 mm.

Claims

1. A flexible light strip, comprising: A lamp tube extending in one direction, at least one of its two ends being a port, and including two opposing sidewalls, a bottom wall, and a top wall, the two sidewalls, the bottom wall, and the top wall forming a cavity, the two sidewalls and the bottom wall being made of opaque material, and the top wall being made of translucent material; and a lamp strip disposed within the lamp tube, the lamp strip having a flexible substrate and a plurality of light-emitting elements, the plurality of light-emitting elements being disposed on the flexible substrate and arranged at intervals along the direction; wherein, the angle between a light-emitting surface of each light-emitting element and the top wall is 0 to 90 degrees; and wherein, the distance between each light-emitting element and the inner wall surface of the lamp tube ranges from 0.5 to 5 mm.

2. The flexible light strip as described in claim 1, wherein, The two ends of the lamp tube are the ports, and when the two ports are in close contact with each other, the distance between the two light-emitting elements adjacent to each port is equal to the spacing.

3. The flexible light strip as described in claim 2 further includes a light-transmitting covering material covering the two ports, such that one port is in close contact with the other port.

4. The flexible light strip as described in claim 2 further includes two optical compensation layers, each corresponding to the light-emitting element adjacent to the port, disposed in the cavity and positioned above the light-emitting surface of the light-emitting element.

5. The flexible light strip as described in claim 2 further includes two optical diffusion sections, respectively disposed outside the two ports, wherein the thickness of each optical diffusion section in the direction is less than or equal to 1 mm.

6. The flexible light strip as claimed in claim 1 further includes a light guide layer disposed within the cavity and located above the light-emitting surface of each of the light-emitting elements.

7. The flexible light strip as described in claim 1, wherein, The lamp tube also includes a first docking structure and a second docking structure, which are respectively disposed at the two ends. The first docking structure and the second docking structure can be docked and fixed to each other, so that the lamp tube is a ring-shaped lamp tube.

8. The flexible light strip as described in claim 1, wherein, The lamp tube also includes a first docking structure disposed at the port, and the first docking structure can be docked and fixed with a second docking structure of another lamp tube.

9. The flexible light strip as described in claim 1, wherein, The light diffusion rate of the top wall is 60% to 95%.

10. The flexible light strip as claimed in claim 1, wherein, The thickness of the top wall is 0.1 mm to 2.5 mm.

11. The flexible light strip as claimed in claim 1, further comprising a winding member, wherein the light tube further comprises a clamping structure forming a clamping space containing the winding member.

12. The flexible light strip as described in claim 11, wherein, The winding element is an elastic helical component that extends along the extension direction of the lamp tube.

13. The flexible light strip as described in claim 12, wherein, The winding element includes at least two helical sections, the at least two helical sections having the same or different pitches.

14. The flexible light strip as claimed in claim 11, wherein, The clamping structure is a semi-open groove structure, which allows the winding member to be inserted into the clamping space from the side and detachably fixed to the lamp tube.

15. The flexible light strip as claimed in claim 11, wherein, When the winding element is disposed on the outer periphery of a columnar structure, the flexible light strip can be arranged in a spiral along the columnar structure.

16. The flexible light strip as described in any one of claims 1 to 15, wherein, The lamp tube includes a light-transmitting portion and a light-shielding portion, the light-transmitting portion forming the top wall and the light-shielding portion forming the bottom wall.

17. The flexible light strip as claimed in claim 16, wherein, The light-transmitting portion extends from the top wall to a portion of the bottom wall to increase the lateral light emission range of the flexible light strip.
