Lighting module, distance measuring device, movable body, and light source drive circuit

A lighting module comprising:

• a voltage-current controller configured to control a voltage value and a current value of power supplied from an external power supply;
• a capacitor to be charged with power supplied from the voltage-current controller;
• a laser light source configured to emit laser light, driven by a current supplied from the capacitor;
• a first field effect transistor electrically connected in series to the laser light source,
• the first field effect transistor being configured to control a pulse width of the current flowing through the laser light source in accordance with a first voltage value applied to a gate of the first field effect transistor;
• a second field effect transistor electrically connected in series to the laser light source,
• the second field effect transistor being configured to:
• change in resistance value in accordance with a second voltage value applied to a gate of the second field effect transistor;
• and
• control, with the resistance value, a peak value of the current flowing through the laser light source;
• and
• circuitry configured to:
• control the first voltage value applied to the first field effect transistor;
• and
• control the second voltage value applied to the second field effect transistor, to control the resistance value of the second field effect transistor.
