Flexible lighting device including a protective conformal coating

Abstract

A lighting element is provided, comprising: a flexible substrate (510, 530, 110); first conductive element (130) and second conductive element (140) located on the flexible substrate (510, 530, 110); a light-emitting element (210) having a first contact (230) and a second contact (240) that are both on a first surface of the light-emitting element (210), the light-emitting element (210) emitting light from a second surface opposite the first surface; a first conductive connector (235) located between the first conductive element (130) and the first contact (230), electrically connecting the first conductive element (130) to the first contact (230); a second conductive connector (245) located between the second conductive element (140) and the second contact (240), electrically connecting the second conductive element (140) to the second contact (240); a first protective conformal coating (1565, 1675) located adjacent to the second surface; and an affixing layer (540) located between the flexible substrate (510, 530, 110) and the first protective conformal coating (1565, 1675), the affixing layer (540) affixing the first protective conformal coating (1565, 1675) to the flexible substrate (510, 530, 110),wherein the first protective conformal coating (1565, 1675) is substantially transparent to light.

However, due to the complex design of LEDs, the resulting devices can be relatively thick, limiting their use in space-sensitive situations

[0005] Furthermore, the desire to keep the device as thin as possible limits the size of the LEDs that can be used in a lighting device, and thus the amount of light that a lighting device can produce

[0006] In addition, many LED devices are rigid devices, which limit their use in many situations due to their fixed size and shape
