a carrier comprising a lighting portion and an extending portion;
a plurality of light-emitting units disposed on the lighting portion, wherein the lighting portion is transparent to light emitted from the light-emitting unit; and
a protection layer covering the plurality of light-emitting units, and the lighting portion,
wherein the extending portion is exposed from the protection layer.
2. The light-emitting module according to claim 1 , wherein the carrier has a flexible structure.
3. The light-emitting module according to claim 1 , wherein the extending portion has a length longer than that of the lighting portion.
4. The light-emitting module according to claim 1 , wherein the lighting portion and the extending portion are formed in one integrated piece.
5. The light-emitting module according to claim 1 , wherein the protection layer has a surface temperature not higher than 50° C. during operation.
6. The light-emitting module according to claim 1 , wherein the plurality of light-emitting units has a dimension less than 150 μm×150 μm.
7. The light-emitting module according to claim 1 , wherein the protection layer comprises biomedical grade elastomer, or biomedical grade silicone rubber.
8. A light-emitting module, comprising:
