Tiled Platformer with Slopes - Libgdx Tiled+Box2D

I’m having trouble thinking of a way to implement slopes in a platformer using Tiled Map Editor and Box2D. I have a tiled platformer working with my own gravity, collision detection and movement using Tiled, but I simply don’t know how to add smooth slopes in. I would also like to use Box2D for the lighting.

Could someone please give me some ideas or hints on how I can get it working?

Thanks
