摘要： A light emitting element driver composed of two transistors, one ground resistor, one inductance and a single capacitor is arranged to drive an LED with a supplied voltage as low as about 0.92 V. The transistors include an NPN transistor and a PNP transistor, the base of the PNP transistor being connected to the ground resistor and the base of the NPN transistor being connected to the collector of the PNP transistor, with the capacitor being connected between the base of the PNP transistor and the node connecting the collector of the NPN transistor to the inductance and to the LED.

摘要： The sensitivity adjusting equipment applied to a photoelectric smoke detector is provided. The photoelectric smoke detector includes a luminous component for providing an input light and a detecting component for receiving an even output light. The sensitivity adjusting equipment includes a light-scattering device having a scattering component and an adjustable hole for scattering the input light evenly and adjusting an intensity of the input light so as to output the even output light to the detecting component. The sensitivity adjusting equipment also includes a movable platform having a first brace connected to the photoelectric smoke detector and a supporting base having a second brace connected to the light-scattering device. The movable platform is moved to make the photoelectric smoke detector and the light-scattering device combined to adjust the sensitivity of the photoelectric smoke detector.
