Abstract
The invention relates to a multicolor light source device. The multicolor light source device comprises a power supply, full-color LED lamps, an LED lamp circuit board, a light guide plate, a main control board, a diffusion plate, a pressing sleeve and an abrasive sand plate. The full-color LED lamps are evenly distributed around the light guide plate to form a round light-emitting array, backlight color data are set through a touch display screen and transmitted to the main control board through a line, the proportion of three primary colors which are red, green and blue is controlled and adjusted through an LED gray scale setting module on the main control board, and accordingly different backlight colors are formed by mixing. The multicolor light source device has the advantage of being capable of greatly improving image collecting effect.
Description
Technical field
What the present invention relates to is a kind of light supply apparatus, particularly a kind of polychromatic source device.
Background technology
The features such as image is two-dimentional print media, has information density large, and content is lively, perceptual, easily accepted by people.And image can be crossed over aphasis, enhancement people thoughts communication widely.IMAQ is all widely used in many industries, by the image gathering is identified and judged, controls comings and goings, makes operation more accurate, has the advantages such as confidence level, hommization, intellectuality.
Backlight when conventional art gathers target sample as imageing sensor mainly with monochromatic source greatly, because monochromatic source can only produce the light of certain particular color, wavelength is single, imageing sensor can not suitably be regulated for the target sample of different colours, can not carry out light filling, the samples pictures contrast adjustability therefore gathering is poor.Monochromatic source can not be carried out suitable blend of colors for different samples according to actual needs, and to obtain a kind of backlight of applicable this sample, it is only suitable for the backlight as some sample, has very strong limitation.The samples pictures that monochromatic source can not make imageing sensor collect has high-contrast, and IMAQ is second-rate.
Summary of the invention
For addressing the above problem, the invention provides a kind of multiple different collection background, polychromatic source device that IMAQ quality is improved of providing.
A kind of polychromatic source device, comprise power supply, all-colour LED (Light-Emitting Diode) lamp, LED lamp circuit board, LGP, master control borad, diffuser plate, clamping sleeve and frosted plate, it is characterized in that: on the uniform LED of the being arranged on lamp circuit board of full-color LED lamp, LGP and diffuser plate are arranged on LED lamp circuit board, frosted plate is arranged on rotating base, clamping sleeve is arranged on rotating base and compresses frosted plate, full-color LED lamp is distributed on LGP surrounding, LED lamp circuit board is connected with master control borad by circuit, and power supply is connected with master control borad.
Full-color LED lamp is distributed on LGP surrounding, form a circular luminous array, by touch display screen, backlight color data are set, to be transferred to master control borad by circuit, controlled to adjust the proportion of three kinds of primary colors of red, green, blue by the all-colour LED gray scale setting module on master control borad, thereby blend different backlight colors, bias light is spread in the detection storehouse of sealing uniformly by LGP and diffuser plate.Three kinds of color of light of red, green, blue are called the three primary colors of light, if three kinds of coloured light of red, green, blue are pressed to different proportion to be mixed, the technical program adopts a circular luminous array of several full-color LED lamp composition, then by PWM(pulse width modulation) intensity of illumination of red, green, blue three looks of light regulating technology to all full-color LED lamps carries out linear regulation, by regulating the proportion of three kinds of colors, thereby blend different backlight colors.
The beneficial effect of the technical program is as follows: adopt polychromatic light lighting system that multiple different collection background can be provided, improved IMAQ quality.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, structure composition of the present invention and operation principle are further described in detail.
A kind of polychromatic source device, comprise power supply 2, full-color LED lamp 8, LED lamp circuit board 6, LGP 7, master control borad 3, diffuser plate 9, clamping sleeve 1 and frosted plate 4, it is characterized in that: on the uniform LED of the being arranged on lamp circuit board 6 of full-color LED lamp 8, LGP 7 and diffuser plate 9 are arranged on LED lamp circuit board 6, frosted plate 4 is arranged on rotating base 5, clamping sleeve 1 is arranged on rotating base 5 and compresses frosted plate 4, full-color LED lamp 8 is distributed on LGP 7 surroundings, LED lamp circuit board 6 is connected with master control borad 3 by circuit, and power supply 2 is connected with master control borad 3.
Described full-color LED lamp 8 is distributed on LGP 7 surroundings, form a circular luminous array, by touch display screen, backlight color data are set, to be transferred to master control borad 3 by circuit, controlled to adjust the proportion of three kinds of primary colors of red, green, blue by the all-colour LED gray scale setting module on master control borad 3, thereby blend different backlight colors, bias light is spread in the detection storehouse of sealing uniformly by LGP 7 and diffuser plate 9.Three kinds of color of light of red, green, blue are called the three primary colors of light, if three kinds of coloured light of red, green, blue are pressed to different proportion to be mixed, the technical program adopts several full-color LED lamps 8 to form a circular luminous array, then by PWM light regulating technology, the intensity of illumination of red, green, blue three looks to all full-color LED lamps 8 is carried out linear regulation, by regulating the proportion of three kinds of colors, thereby blend different backlight colors.
As mentioned above, given scheme content, can derive similar technical scheme in conjunction with the accompanying drawings and embodiments.In every case be the content that does not depart from technical solution of the present invention, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present invention, all still belong in the scope of technical solution of the present invention.
