发明名称 Photosensor control unit
摘要 A photosensor control unit for use in a lighting module has a plurality of LEDs, a light sensor, and a switch adapted to operably control the plurality of LEDs responsive to the light sensor. The plurality of LEDs are adapted to be mounted in the lighting module, and are configured to produce light having wavelengths within a first range of wavelengths. The light sensor is adapted to be mounted in the lighting module adjacent the plurality of LEDs, and is responsive to light having wavelengths within a second range of wavelengths. The second range of wavelengths is exclusive of the first range of wavelengths. The switch is adapted to operably control the plurality of LEDs responsive to the light sensor such that the plurality of LEDs emit light having wavelengths within the first range of wavelengths responsive to the presence or absence of light within the second range of wavelengths.
