1. A light-emitting module, comprising:
a first terminal;
a second terminal;
a first light source connected between the first terminal and the second terminal;
a second light source and a third light source connected between the first terminal and the second terminal, in anti-parallel with the first light source;
a switching circuit; and
a control circuit to control the switching circuit, causing a first voltage to be applied to the first terminal and a second voltage lower than the first voltage to be applied to the second terminal during a first time period, and causing a third voltage to be applied to the first terminal and a fourth voltage higher than the third voltage to be applied to the second terminal during a second time period prior or subsequent to the first time period,
the first, second, and third light sources being aligned in a first direction along a light-emitting surface, with the first light source between the second light source and the third light source.
