The present invention relates to a device comprising physical properties controlled by a microstructure and a method of manufacturing the same. The present invention discloses a base layer having a patterned surface; and a two-dimensional structure layer formed on the patterned surface of the base layer, the two-dimensional structure layer extending on and in compliance to topography of the patterned surface of the base layer, such that change of physical properties of the two-dimensional structure layer conforms to the stress generated along the topography.

Device comprising physical properties controlled by microstructure and method of manufacturing the same

The present invention provides an LED illumination device including a base, at least one flexible circuit board and a plurality of LEDs. The at least one flexible circuit board is used for covering the base. The LEDs are mounted on the flexible circuit board. The present invention utilizes a flexible circuit board that can conform to the base having a 360 degree curved surface and a 3D solid structure to efficiently change the viewing angle of the LEDs so as to provide 360 degree viewing angle. Furthermore, a single flexible circuit board can be utilized to cover the base to provide a 360 degree viewing angle. Therefore, the LED illumination device of the present invention can reduce manufacturing cost and simplify the manufacturing process.
