A tunable laser based light source for Li-Fi communication comprising a laser (), a first optical element (), and a second optical element (). The first optical element () is configured to reflect and/or refract a scanning beam () emitted from the laser (). The second optical element () is configured to broaden the scanning beam () reflected/refracted by the first optical element (). The scanning beam () is configured to scan a scanning area extending with a first scanning length in a broadening direction (SI) and a second scanning length in a scanning direction (S). The second optical element () is configured to broaden the scanning beam () in the broadening direction (S) to a width larger than the first scanning length, and the laser () and the first optical element () are configured to cooperate to enable the scanning beam () to be swept along the scanning direction (S).
