Embodiment 1

[0038] 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 .

[0039] Specifically, the flexible light-transmitting substrate 11 is made of materials 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.

[0040] The bendable circuit layer 12 is formed on the upper surface 111 of the flexible light-transmitting substrate 11 by printing, sputtering, etc....

Embodiment 2

[0049] 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 .

[0050] 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 15a covers the lower surface 112 of the flexible transparent substrate 11, and the second fluorescent patch 15b covers the flexible transparent cover. 14, so as to achieve the effect of double-sided light emission.

Abstract

The invention describes a flexible LED package, which comprises: a flexible light-transmitting substrate, a bendable circuit layer, at least one light-emitting diode, a flexible light-transmitting cover body and at least one fluorescent patch, wherein the flexible light-transmitting substrate has an upper surface and a lower surface; the bendable circuit layer is provided on the upper surface of the flexible light-transmitting substrate; the light-emitting diode is provided on the upper surface of the flexible light-transmitting substrate and electrically connected to the bendable circuit layer; the flexible light-transmitting cover body is provided on the upper surface of the flexible light-transmitting substrate and covers the light-emitting diode and the bendable circuit layer; and the fluorescent patch covers one of the flexible light-transmitting cover body and the lower surface of the flexible light-transmitting substrate. Therefore, the inventive flexible LED package can obtain an effect of uniform dual-sided light-emitting.

Description

technical field [0001] The invention relates to an LED package structure, in particular to a flexible LED package capable of emitting light from both sides. Background technique [0002] Light-Emitting Diode (LED) has the advantages of small size, low power consumption, high brightness, high color performance, fast response, and can be used continuously for 20,000 to 50,000 hours. Lighting technology has gradually replaced solid-state light source (SSL) systems such as traditional fluorescent lamps and light bulbs, and is widely used in electronic products, display device backlights, indicator lights, mobile communications and other fields. [0003] Generally speaking, in order to improve the luminous efficiency of the traditional LED package structure, a reflective layer is usually arranged on one side of the LED package structure, and a light-transmitting substrate is arranged on the other side opposite to the reflective layer, so that the light source can concentrate on p...
