Abstract
The utility model discloses a dental LED reflection operation lamp control system. An external signal is received by an infrared sensing module, the external signal is fed back to a single chip microcomputer, a PWM pulse width modulation signal is generated to control outputs so as to control the switch-on and the switch-off of a mouth lamp and the dimming of a constant-current adjustable output chip. The single chip microcomputer is a 8 bit single chip microcomputer whose model is At89s51. The single chip microcomputer is connected with a status display module. Through multiple tests, the conclusion that the dental LED reflection operation lamp control system has a more stable infrared control effect than original products of the same type is validated.
Description
Technical field
The utility model relates to and utilizes infrared induction to carry out the control field of LED lamp, has been specifically related to a kind of dentistry LED reflection operating lamp control system.
Background technology
The deficiency of domestic oral cavity LED lamp manufacturing experience has been brought the many-sided deficiency of this series products, causes the function imperfection, unstable properties, and some defectives in the design.And existing domestic oral cavity LED lamp all exists infrared induction to receive the big problem of extraneous light influence.Its problem is that mainly the infra-red range of receiving element reception is extensive, receives airborne infrared interference easily.
The utility model content
In view of this, the purpose of the utility model embodiment is to provide a kind of dentistry LED reflection operating lamp control system, and in order better to improve the function of LED lamp, performance is more stable, and remedies some other defective.
A kind of dentistry LED reflection operating lamp control system of the utility model is accepted external signal by infrared induction and is fed back to single-chip microcomputer and produce the PWM pulse-width signal and control output and be used to control closing and the adjustable pio chip of the constant current of light modulation of mouth lamp.
Preferably, said single-chip microcomputer is that model is 8 single-chip microcomputers of At89s51.
Preferably, said single-chip microcomputer is connected with the state display module.
Compared with prior art, the advantage of the utility model is:
Its principle is that energising is sent out LED light to make the LED issued light be gathered into operation through speculum again and gone up used light shape.
Get through the test of many times authentication, this product is more stable than the infrared control of original product of the same type.
