The principle of controlling the light source 4 to emit light by the controller in the embodiment of the present invention will be described in detail with reference to specific embodiments.

The light signal emitted by the light source 4 can be used to indicate some conditions inside the light module, such as the operating state of the light module, or the operating environment condition of the light module. It should be noted that, in the embodiment of the present invention, the light signal emitted by the light source 4 may be used to indicate any condition of the light module, including but not limited to the operating state of the light module.

The working state of the optical module can be controlled by the controller, the controller monitors the working state of the optical module in real time and sends a control signal to the light source, and the control signal can indicate the normal working state of the optical module and also can indicate the abnormal working state of the optical module. The light source can emit different lights according to the control signal emitted by the controller so as to indicate different working states of the light module. The controller may be disposed inside the optical module or outside the optical module.

When the working voltage, the working temperature, the emitted light power, the received light power and other states of the optical module are abnormal, namely the monitoring value exceeds a normal range, the controller can send a control signal to the light source 4 to enable the light source 4 to send an optical signal for indicating the abnormal working state of the optical module according to the received control signal, and the optical signal for indicating the abnormal working state of the optical module can be led out to a second bending part and a handle or an unlocking handle 6 of the optical module from the inside of the optical module through the light guide structure 3 in the optical module, so that the abnormal state of the optical module can be visually embodied outside the optical module, the abnormal working state of the optical module can be quickly positioned, and the detection efficiency for positioning the abnormal optical module is improved.

Certainly, when the working state of the optical module is in a normal working state, the controller can also send a control signal to the light source 4, so that the light source 4 sends an optical signal for indicating the normal working state of the optical module according to the received control signal, and the optical signal for indicating the normal working state of the optical module can be led out to the second bending part and the handle or the unlocking handle 6 of the optical module from the inside of the optical module through the light guide structure 3 in the optical module, so that the normal state of the optical module can be visually embodied outside the optical module, and thus, a maintenance worker of the optical module can immediately perceive that the light emitting module is in the normal working state according to the observed optical signal.

In the above optical module, the controller that sends the control signal to the light source 4 may be a micro control unit MCU inside the optical module, or may be an MCU disposed outside the optical module, and is mainly used to monitor the operating state of the optical module and send the control signal to the light source 4.

The embodiment of the invention provides two ways for realizing the transmission of the control signal to the light source 4.

The first implementation manner comprises the following steps: the circuit board is provided with an internal controller, and the internal controller is connected with the light source through a signal wire; an internal controller for sending a control signal to the light source; and the light source is used for receiving the control signal sent by the internal controller and sending out an optical signal according to the control signal.

Further, a register is arranged on the circuit board; the register is used for storing the working state information of the optical module; the internal controller is specifically used for reading the working state information of the optical module stored in the register, detecting whether abnormal information exists in the working state information of the optical module, and if the abnormal information exists, sending a control signal indicating the abnormal position of the optical module to the light source; and if not, sending a control signal indicating the normal work of the optical module to the light source.

Further, for the above two implementations of sending the control signal to the light source 4, one or more indicator lights are provided. The number of the indicator lights arranged on the circuit board in the embodiment of the present invention is not particularly limited. The indicator light is used for: when the working state of the optical module is normal, a first optical signal is sent out according to the control signal; when the working state of the optical module is abnormal, a second optical signal is sent out according to the control signal; when the light module is in different abnormal positions, the second light signals sent by the indicator lamp are different.

Wherein the frequency of the second optical signal is different for different abnormal positions of the optical module. For example, if the operating voltage of the optical module is abnormal, the frequency of the indicator light emitting red light is 1Hz, if the operating temperature of the optical module is abnormal, the frequency of the indicator light emitting red light is 2Hz, if the bias current of the optical module is abnormal, the frequency of the indicator light emitting red light is 4Hz, if the light emitting power of the optical module is abnormal, the frequency of the indicator light emitting red light is 8Hz, and if the light receiving power of the optical module is abnormal, the frequency of the indicator light emitting red light is 16 Hz.

For example, if the working state of the light module is normal, all the indicator lights display green light; if the working voltage of the optical module is abnormal, the indicator lamp emits red light; if the working temperature of the optical module is abnormal, the indicator lamp emits blue light; if the bias current of the optical module is abnormal, the indicator lamp emits yellow light; when the light emitting power of the optical module is abnormal, the indicator lamp emits purple light, and when the light receiving power of the optical module is abnormal, the indicator lamp emits white light.
