Abstract:
The disclosure provides an optical module, including a housing, a circuit board and a light conducting structure; a portion of the light conducting structure is disposed in the housing, another portion of the light conducting structure juts out from the housing; the circuit board is provided with a light source, and the light conducting structure is configured to conduct light emitted by the light source to an outside of the housing. The optical conducting module in the optical module can conduct light emitted from the optical module to outside of the optical module. The optical module allows the state inside the optical module to be conducted to and displayed in the outside of the optical module with optical signals as propagation medium. The state inside the optical module can be directly learned from the outside of the optical module housing, thereby extending application scenarios of the optical module.
