In addition; AC power also connects rectification circuit and direct-current voltage reducing circuit realizes that output light current direct voltage offers signal processing circuit as working power; being serially connected in hand switch in the current supply circuit that is made of AC power and desk lamp is convenient to the user and artificially controls desk lamp and open and close; the desk lamp of a kind of automatic switch provided by the invention and automatic brightness adjustment; by utilizing infrared sensor in conjunction with phase shift trigger; controllable silicon; load signal sample circuit and synchronizing signal sample circuit; realization has the man-hour desk lamp to open automatically; desk lamp is closed automatically behind the unmanned certain hour; both having solved existing desk lamp forgets simultaneously to turn off the light owing to user's time departure is long and causes the problem of waste of energy; avoided again just having entered the room as the user; go down at dark surrounds and manually to turn on light and unhandy problem; by light sensor in conjunction with phase shift trigger; controllable silicon; load signal sample circuit and synchronizing signal sample circuit; realization is according to ambient light intensity adjustments desk lamp supply power voltage and then change desk lamp brightness; make ambient light illumination remain in the comfortable scope of human eye; having solved existing desk lamp brightness fixes; when the use desk lamp is learnt or is worked; surrounding environment brightness and desk lamp difference in brightness are too small; eyesight is tired easily; surrounding environment brightness and desk lamp difference in brightness are excessive; problem that again can the intense stimulus eyes; be beneficial to vision protection and eye health; the present invention is simple in structure; convenient and practical; not only be convenient to produce, and cost is very cheap is suitable for extensive popularization.
The above; only be the preferable embodiment of the present invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
