A lighting device includes a first platform, a light-emitting unit, a second platform and a connecting member. The light-emitting unit is disposed on the first platform for emitting light beams. The second platform is made of transparent material and has a chamber therein. The chamber contains immiscible first and second fluids with different refractive indices. The connecting member is used for interconnecting the first platform and the second platform and transmitting inclination of the second platform. The light beams are refracted by the first and second fluids when the second platform is inclined at a specified inclining angle. |
