Description
Technical field
The utility model belongs to a kind of light source, specifically is to be used for industrial band light source of carrying out various materials, strip material position probing.
Background technology
In industrial production, need use band light source during for various materials location, displacement detecting, usually use the fluorescent lamp of charged sense or electric ballast, but be power frequency with the fluorescent lamp glow frequency of Inductive ballast, measuring system can be subjected to the interference of other use power frequency powered light sources; And normally used electric ballast frequency instability; And the brightness of fluorescent lamp itself can be subjected to the influence of dust, dirt, ambient light in the environment etc. again, makes to measure to produce error or instability.Therefore, need to propose architecture advances, performance is better, is difficult for band light source affected by environment.
The utility model content
The purpose of this utility model is at above-mentioned technical problem, proposes the industrial banded high frequency light source of a kind of modulation system.This light-source structure novelty is perfect, is difficult for affected by environmently, and performance is better more stable.
The purpose of this utility model is achieved through the following technical solutions: the industrial banded high frequency light source of modulation system, be provided with the sight fluorescent tube, circuit board, it is characterized in that: described power supply is a direct current 24V power supply, be provided with the power supply input circuit that connects in regular turn, power-switching circuit, vibration frequency division drive circuit, constant temperature control circuit, fluorescent tube is connected with described vibration frequency division drive circuit, and be provided with brilliance control and build-up of luminance control circuit, this circuit and power-switching circuit and vibration frequency division drive circuit carry out control connection, also are provided with luminance detection circuit and are connected with brilliance control and build-up of luminance control circuit; Described fluorescent tube and circuit board are sealed in the transparent high temperature resistant shell.
The utility model adopts quartz oscillator to produce high-frequency oscillation signal, and to the frequency that needs, as 1KHz, it is luminous to deliver to drive circuit driving fluorescent lamp through digital frequency division for this signal.Luminance detection circuit detects the pulsewidth that luminance signal feeds back to intednsity circuit control drive circuit, makes fluorescent lamp luminous with constant luminance.Stablize and constant temperature makes the oscillating circuit frequency stabilization, fluorescent lamp is luminous.And adopt whole constant temperature control electricity we, make the light source luminescent frequency stabilization, brightness stability becomes and is fit to the body constant temperature that the industry spot high-acruracy survey is used, and makes the light source luminescent frequency stabilization, brightness stability becomes and is fit to the industry spot high-acruracy survey.
It is perfect to the utlity model has novel structure, and brightness stability is regulated control flexibly, is not subject to the advantage of such environmental effects.
