The course of work and operation principle
The utility model adopts LED to do light emitting source, and direct current supply is without stroboscopic, and electromagnetic-radiation-free is without ultraviolet ray and infrared ray, and the small lamp bulb life-span is long, energy-efficient; In the time that accumulator electric-quantity reached the minimum voltage of putting, stop, to the power supply of LED lamp, using 220V AC power instead and becoming DC voltage to power to LED lamp through transformation voltage stabilizing.When solar power silicon tabula rasa voltage use during in charge in batteries scope, battery starts charging, detects when cell voltage reaches maximum charging voltage and stops charging, prevents to overcharge phenomenon and reduces battery life.In the time of charge in batteries, adopt solar power silicon tabula rasa to power to single-chip microcomputer by 7805 mu balanced circuits, after charging, use battery instead and power to single-chip microcomputer.
Adopt the brightness of photo resistance detection background, by AD analog-to-digital conversion, the optical signal of simulation is converted into the signal of telecommunication and is input to single-chip microcomputer, by single-chip microcomputer, signal is carried out to analyzing and processing, the brightness of the timely adjustable desk lamp of control single chip computer, in the time that detection background brightness exceeds setting value, single-chip microcomputer sends signal at stop LED and drives.
Adopt infrared sensor, the time difference of infrared transmitting tube and receiving tube is transformed and is input to single-chip microcomputer by AD, single-chip microcomputer is processed signal, calculate infrared sensor and user's distance, regulate the light on and off of LED lamp, in the time that distance is less than certain value and light sensor and detects light and too secretly reach setting value, open LED desk lamp, user regulates lamplight brightness darker the closer to desk lamp.When distance exceeds setting value, LED lamp is closed in time delay for three minutes automatically.
advantage of the present utility model and good effect:
(1) adopt light sensor to change automatic adjustable desk lamp brightness according to background light intensity, make light remain comfortable soft brightness.(2) adopt infrared sensing to detect the distance of people and desk lamp, reach people and carry out lamp and open the effect turning off the light when you leave, do not need manual operation to save again electric energy, (3) employing LED does lamp source and has eliminated the injury of stroboscopic to eyes.(4) adopt solar power silicon tabula rasa to do the environmental protection of desk lamp power supply energy-efficient.
