Guaranteeing consistent light over time
Lighting intensity levels from LED lighting will naturally degrade over time. However, with Gardasoft Triniti Intelligent Lighting the illumination intensity for your application can be guaranteed over your application life-time.
- Camera identifies optimum illumination intensity for application
- Image processing application monitors acceptable operating illumination bandwidths
- Light controller automatically adjusts lighting intensity if necessary
In this example there is a GigE Vision camera and a Triniti-enabled light. In addition to its designated function, the camera also measures a defined area of the scene for illumination intensity (effectively a "test card"). This is continuously reported to the Image Processing application, where it is compared to the predetermined acceptable bandwidth of illumination for this particular inspection. If the bandwidth is contravened, then a signal is sent to the lighting controller to increase the lighting intensity; the controller will then increase the intensity until illumination levels are back within the acceptable application bandwidths.
Because of the Triniti system, the intensity of the light can be increased in a completely protected way because the Controller is aware of the maximum intensity characteristic of the light. So the continuous cycle described for this application could be continued until the maximum light intensity had been reached. Note that the lighting controller would have sent a "preventive maintenance" warning signal to replace the light a while before any maximum illumination figure had ever been met.
