Embodiment 1
[0024] see figure 1 , is a schematic cross-sectional view of a flexible LED package 10 according to Embodiment 1 of the present invention. The flexible LED package 10 of this embodiment includes a flexible light-transmitting substrate 11, a bendable circuit layer 12, and at least one light-emitting diode 13. A flexible transparent cover 14 and a fluorescent patch 15 .
[0025] Specifically, the flexible transparent substrate 11 is made of a material with high light transmission and flexibility, such as polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyethylene Imide (PI), polymethylmethacrylate (PMMA) or polyethersulfone (PES), etc., but not limited thereto. In this embodiment, the flexible light-transmitting substrate 11 has an upper surface 111 and a lower surface 112 with a thickness of 0.01-1 mm.
[0026] The bendable circuit layer 12 is formed on the upper surface 111 of the flexible light-transmitting substrate 11 by printing, sputtering, etc., of a...
Embodiment 2
[0035] see figure 2, is a schematic cross-sectional view of a flexible LED package 10' in Embodiment 2 of the present invention. The difference from Embodiment 1 is that the flexible light-transmitting cover 14 of the flexible LED package in this embodiment may not include fluorescent light. The powder 141 is further covered on the flexible transparent cover 14 with another fluorescent patch 15 .
[0036] Specifically, in this embodiment, the flexible LED package includes a flexible light-transmitting substrate 11, a bendable circuit layer 12, at least one light-emitting diode 13, a flexible light-transmitting cover 14 and at least A fluorescent patch 15 . Among them, the number of fluorescent patches 15 is two, the first fluorescent patch 153 covers the lower surface 112 of the flexible transparent substrate 11, and the second fluorescent patch 154 covers the flexible transparent cover. 14, so as to achieve the effect of double-sided light emission.
[0037] It is worth n...
