Embodiment Construction

[0029] figure 1 A cross-sectional view of the lighting device according to the first embodiment of the present invention is shown. The lighting device includes a flexible substrate 11 . The flexible substrate 11 includes a plastic layer 12 , a first flexible insulating layer 14 , and a second flexible insulating layer 16 . The plastic layer 12 is interposed between the first flexible insulating layer 14 and the second flexible insulating layer 16 . The first flexible insulating layer 14 is used to support the plastic layer 12 . The second flexible insulating layer 16 is located on the plastic layer 12 .

[0030] In an embodiment, the minimum strain stress of the plastic layer 12 is greater than the minimum strain stress of the first flexible insulating layer 14 and the second flexible insulating layer 16, or the minimum strain stress of the plastic layer 12 is greater than that of the first flexible insulating layer 14. The elastic recovery force of the layer 14 and the se...

Abstract

The invention discloses a flexible substrate and a lighting device including the flexible substrate. The flexible substrate includes a plastic layer, a first flexible insulating layer and a second flexible insulating layer. The plastic layer is sandwiched between the first flexible insulating layer and the second flexible insulating layer. The minimum varying stress of the plastic layer is greater than the minimum varying stress of the first flexible insulating layer and the second flexible insulating layer, or the minimum varying stress of the plastic layer is greater than the elastic restoring force of the first flexible insulating layer and the second flexible insulating layer, so that the flexible substrate has the capability of low anti-deformation and can be randomly bent or crossed.

Description

technical field [0001] The invention relates to a flexible and foldable substrate, and in particular to an illuminating device with a flexible and foldable substrate. Background technique [0002] Generally, a lighting device with a flexible design cannot withstand multiple times of reciprocating bending, and will easily break after being bent. Moreover, the angle of bending is limited, so the service life and diversity are very limited. Contents of the invention [0003] The object of the present invention is to provide a flexible substrate and a lighting device including the flexible substrate, which are convenient to use, have multiple variability and long life. [0004] To achieve the above purpose, the present invention provides a flexible substrate. The flexible and foldable substrate includes a plastic layer, a first flexible insulating layer and a second flexible insulating layer. A plastic layer is interposed between the first flexible insulating layer and the s...
