Abstract
A light-out detection device includes a mounting structure with a sensor for measuring a light output, wherein the mounting structure is configured as retrofittable structure to mount at a front side of a signal, a processor board with an actuator, the processor board being operably coupled to the at least one sensor, wherein the processor board is configured to control the actuator such that the actuator switches from a first state to a second state when the measured light output is less than a predefined threshold.
Claims20
A light-out detection device comprising:
- a mounting structure comprising at least one sensor configured to measure light emitted from a light source installed in a wayside signal unit, wherein the mounting structure is configured as retrofittable structure to mount at a front side of the light in the wayside signal unit,
- a processor board comprising at least one actuator, the processor board being operably coupled to the at least one sensor,
- wherein the processor board is configured to control the at least one actuator such that the at least one actuator switches from a first state to a second state when the measured emitted light is less than a predefined threshold.
A wayside signal unit comprising:
- a signal head with one or more signal lights,
- a light-out detection device comprising:
- a mounting structure comprising at least one sensor configured to measure light emitted from a signal light source installed in the signal head, wherein the mounting structure is configured as retrofittable structure to mount at a front side of the signal light,
- a processor board comprising at least one actuator, the processor board being operably coupled to the at least one sensor,
- wherein the processor board is configured to control the at least one actuator such that the at least one actuator switches from a first state to a second state when the measured emitted light is less than a predefined threshold.
