Patent ID: 7871836

Claim:
A method of manufacturing a bendable solid state lighting (SSL), comprising: depositing a first metal layer and a second metal layer with a predetermined circuit layout pattern and structure region pattern on both sides of a flexible substrate respectively, wherein a plurality of bonding pads is formed on the structure regions in the structure region pattern, and is used for being electrically connected to the first metal layer; and arranging a plurality of LED dies on the structure regions in an array, and bonding the LED dies with the corresponding bonding pads, such that the LED dies are conducted with current via the circuit layout of the first metal layer on the flexible substrate, so as to form a planar light source, wherein the second metal layer provided on the flexible substrate is a metal coating with high reflectivity and scattering rate, so as to increase the forward light-emitting efficiency for the LED dies, and also reduce the ratio between the light intensity at the axial area of the LED die and that at the surrounding area of the LED die, thus improving the light uniformity of the planar light source.
