Abstract

Disclosed is a flexible light strip made of fluorescent material, including a substrate integrated with a plurality of flip-chips or LEDs arranged in parallel, wherein a phosphor outer layer is wrapped around the substrate, and a cross section of the phosphor outer layer is rectangular or arc-shaped, etc. In the present application, the substrate is wrapped with a flexible phosphor outer layer to achieve its own target color temperature, which simplifies the processing technology and brings the advantage of uniform light emission at the same time. The distance between the light sources, the number of arrangements, and the thickness of the wrapping fluorescent material are controlled, so as to achieve the purpose of uniform light emission. Compared with the existing conventional uniform light emission schemes, the processing technology links are reduced, and the cost is effectively saved, thus the invention has good popularization.

Claims (8)

1. A flexible light strip made of fluorescent material, comprising a substrate integrated with a plurality of flip-chips or LEDs arranged in parallel, and arrangement distances between the flip-chips or LEDs are 0.3 mm to 34 mm;

the substrate is connected to a light blocking layer surrounding both sides and a lower side of the substrate; the light blocking layer has a substantially U-shaped cross-section; and a phosphor outer layer is arranged above the substrate and connected between portions of the light blocking layer on both sides of the substrate, such that a rectangle tube structure is formed by the phosphor outer layer and the light blocking layer;

a gap is arranged between the phosphor outer layer and the plurality of flip-chips or LEDs, such that the phosphor outer layer and the plurality of flip-chips or LEDs are separated by the gap;

a second positioning part is further provided on an inner wall of the light blocking layer above the substrate; the second positioning part is configured to position the substrate.

2. The flexible light strip made of fluorescent material according to claim 1 , wherein sealing plugs are provided at both ends of the substrate.

3. The flexible light strip made of fluorescent material according to claim 2 , wherein a positioning step for positioning the phosphor outer layer is provided in an inner cavity of each of the sealing plugs.

4. The flexible light strip made of fluorescent material according to claim 1 , wherein the substrate is a flexible circuit board formed by splicing a plurality of circuit boards, the circuit boards are connected to each other by welding, and one side of the substrate is provided with a welding part welded with a power cord.

5. The flexible light strip made of fluorescent material according to claim 1 , wherein the phosphor outer layer has a rectangular, arc-shaped or trapezoidal cross section.
