    摘要: A method comprising optically detecting optical output states of a plurality of light sources of an optical device over a test interval; for each light source, optically detecting that the output state of the light source has changed from a first optical condition to a second optical condition; for each light source, optically detecting that the output state of the light source has changed from the second optical condition to a third optical condition; for each light source, determining a first time interval representative of the first optical condition; for each light source, determining a second time interval representative of the second optical condition; for each light source, determining a third time interval representative of the third optical condition; determining a test result for the device based on a comparison of the first, second and third time intervals with pre-stored time intervals.

    摘要: A visible LED light scattering apparatus comprising a substantially hollow spherical cavity including a light entry port arranged to receive visible light from an LED mounted outside the cavity, a light exit port located opposite the entry port and through which the LED light exits the cavity for analysis, and a baffle located in a central region of the cavity in a direct optical path between the entry port and the exit port to interrupt the passage of visible LED light between the entry and exit ports.
