Abstract:
1. An illuminating system, comprising: a light emitting module emitting light with a first frequency; a light sensor detecting an intensity of incident light; and a control module connected to the light emitting module and the light sensor, the control module controlling the light emitting module to emit light with a second frequency according to the intensity of incident light; wherein the light sensor provides a plurality of light intensity signals according to the intensity of incident light detected by the light sensor, and the light intensity signals comprise a first light intensity signal and a second light intensity signal; wherein the control module receives the light intensity signals and then compares each light intensity signal with a threshold value, when the first light intensity signal is lower than the threshold value and the second light intensity signal is higher than the threshold value, the control module controls the light emitting module to emit light with the second frequency.
