Abstract
The invention discloses an LED reflection operating-lamp control system for dentistry department, which receives an external signal through infrared induction and feeds the external signal back to a single chip microcomputer to generate a PWM (Pulse Width Modulation) signal for controlling and outputting an constant-current adjustable output chip which is used for controlling a mouth lamp to shut off and dimming. The single chip microcomputer is an 8-bit single chip microcomputer with the model of At89s51. The single chip microcomputer is connected with a state display module. Authenticated by multiple tests, the LED reflection operating-lamp control system for dentistry department is more stable for infrared control compared with the original products which have the same type as that of the LED reflection operating-lamp control system.
Description
Technical field
The present invention relates to utilize infrared induction to carry out the control field of LED lamp, be 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.
?
Summary of the invention
In view of this, the purpose of the embodiment of the invention 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 present invention 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 invention has the advantages that:
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.
