Abstract:
A sensitivity adjusting equipment applied to a photoelectric smoke detector, wherein said photoelectric smoke detector comprises a luminous component for providing an input light and a detecting component for recovering an even output light, comprising:light-scattering device having a scattering component, wherein said scattering component comprises: a first component having a first hole passing said input light therethrough for scattering said input light evenly and outputting an even light; a second component having a second hole passing said even output light therethrough for receiving said even light so as to output said even output light to said detecting component; and a partition having an adjustable hole passing said even light therethrough disposed between said first component and said second component for transmitting said even light into said second component and outputting said even output light from said second hole at a specific intensity.
