Light module and mobile terminal

A mobile terminal, comprising a light module, a detection module, and a driver module configured to control light emission of a light source of the light module, wherein the driver module is electrically connected to the detection module;

• and
• the light module comprises:
• a support body, wherein the support body has a light path channel;
• a substrate, wherein the substrate is connected to the support body and is located at one end of the light path channel, the substrate is provided with the light source, and the light source is located in the light path channel;
• and
• a light-transmitting element, wherein the light-transmitting element is connected to the support body, so as to seal an opening at the other end of the light path channel;
• wherein
• a side face of the light-transmitting element that faces towards the light source is provided with a first electrical contact point, a second electrical contact point, and a photosensitive coating capable of converting light energy of the light source into electrical energy, the first electrical contact point and the second electrical contact point are electrically connected by the photosensitive coating, and the first electrical contact point and the second electrical contact point are configured to electrically connect to the detection module, so that the detection module detects a value of a voltage across the first electrical contact point and the second electrical contact point;
• the detection module outputs a control signal to the driver module in a case that the value of the voltage is detected to be abnormal;
• and
• the detection module turns off the light source of the light module in response to the control signal, such that the light module stops emitting light.
