Abstract

The invention describes a method of manufacturing an LED module, comprising the steps of providing a translucent encapsulant comprising a number of layers to enclose a number of LEDs of the LED module; modifying the surface structure of an outer surface of a layer to form at least one dense scattering region corresponding to the position of an LED of the LED module; to form at least one sparse scattering region that does not correspond to the position of an LED of the LED module; and to form a transition scattering region between a dense scattering region and a sparse scattering region. The invention further describes an LED module, and a device comprising a device housing and at least one such LED module.

Claims (9)

1. A flexible LED module comprising:

a plurality of LEDs;

a translucent flexible encapsulant comprising a plurality of layers to enclose the plurality of LEDs; and

a scattering pattern formed on the surface of at least one of the plurality of layers to comprise at least one dense scattering region corresponding to the position of one of the plurality of LEDs of the LED module; to comprise at least one sparse scattering region that does not correspond to the position of one of the plurality of LEDs of the LED module; and to comprise a transition region between a dense scattering region and the at least one sparse scattering region

wherein the translucent encapsulant comprises an inner layer applied onto the LED module, and a patterned layer applied onto the inner layer, and

wherein the patterned layer comprises a further scattering pattern on an inner surface adjoining the inner layer.

2. The flexible LED module according to claim 1 , wherein the translucent encapsulant comprises the patterned layer with the scattering pattern on the outermost surface of the translucent encapsulant.

3. The flexible LED module according to claim 1 , wherein the scattering pattern comprises a regular formation of recesses in the surface of the patterned layer.

4. The flexible LED module according to claim 3 , wherein the recesses have an essentially circular shape.
