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.
