Abstract
The utility model directs to a photo enlarge-printing system based on an area-array color LED light source and consists of a light source, a light-mixed device, a negative or a digital light valve and a lens, wherein the light source is an area-array LED array light source. After the emitted light of the light source is controlled by a digital control system composed of a LED digital control circuit, a computer and a control software, the emitted light passes through the light-mixed device for light mixing treatment, shines on the negative or the digital valve, and then images on the photographic paper through the lens, finally larges and prints the photo. The device is based on the traditional negative exposal enlarge-printing and is suitable for printing the digital photo based on the digital light valve. With the adoption of the whole colored LED as the light source for the color enlarge-printing, the color purity of the imaging spectrum, the color expressive force of the imaged photo, the enlarge-printing stability and the image quality as well as the enlarge-printing effect are greatly enhanced.
Description
Technical field
The utility model relates to the field of enlarging and print of the industry of photographing, and specifically refers to a kind of photo enlarging and printing device based on face battle array color LED light source.
Background technology
At present, employed photo enlarging and printing device in the system of enlarging and print of photography industry generally adopts Halogen lamp LED as enlarging and print light source.Based on the structure of the photochrome enlarging print device of traditional egative film, as shown in Figure 1, by halogen light source 11, regulate color filter system 12, light mixing device 13, traditional egative film 14, camera lens 15, mechanical shutter 16 and printing paper 17 and form.Wherein, the white light that sends from Halogen lamp LED, incision angle or time yellow in the color filter system, pinkish red by regulating, the cyan color filter, thus regulated the light composition of RGB in the white light that arrives printing paper, to reach function to the photo toning of enlarging and print.
Occurred a kind of digital enlarging print device based on digital light valve in recent years, it is mainly used in the number of the traditional photo film processor function expansion of enlarging and print.This device still adopts Halogen lamp LED as enlarging and print light source, as shown in Figure 2, just the color filter of regulating color filter system 12 incisions in traditional enlarging print device is replaced to redgreenblue by yellow, pinkish red, cyan, tradition egative film 14 replaces to digital light valve 22, by computer digital light valve is mail in digital picture color separation (RGB) gradation, with time-division three times or more switching color filters, the retractable mechanical system design shutter, thus finish the process of enlarging and print of digital photograph.
Above-mentioned existing two kinds of shortcomings that the photochrome enlarging print device exists in actual application now are summarized as follows:
1, the color representation power of photo imaging is poor
Because device all is to adopt white light that traditional Halogen lamp LED sends as light source in two, according to the photosensitive imaging principle of colored silver salt printing paper, the excitation of light is high more, and the color representation power of imaging photo is good more.And, except that containing RGB light composition, also contain the light of other harmful spectrum of comparison film imaging, thereby influence the color representation power of photo imaging because the white-light spectrum of sending from Halogen lamp LED is a continuous spectrum.
2, big, the poor stability of power consumption
Because the white light Halogen lamp LED life-span is generally 1-3 month, so power consumption is big, aging fast, and the influence that changed by external voltage.So aging quality instability of enlarging and print that causes photochrome of voltage instability and bulb.
3, the efficient of enlarging and print is low
Because acting frequently of color filter system and mechanical shutter, thereby increase the probability of failure of system, made the efficient of enlarging and print reduce significantly.
4, the photo image quality is poor
Because the influence of the optical characteristics of imaging lens and the factors such as " visual angles " of digital light valve, do not possess the even regulation ability with the time Halogen lamp LED, so light can't arrive the center and the both sides of printing paper, thereby makes the quality of photo imaging be affected " evenly ".
The utility model content
The utility model provides a kind of photo enlarging and printing device based on face battle array color LED light source, and is poor with the color representation power that solves photo imaging in the prior art, power consumption big, poor stability, the problems such as efficient is low of enlarging and print.
For addressing the above problem, the utility model provides following solution:
A kind of photo enlarging and printing device based on face battle array color LED light source, this device comprise light source, light mixing device, egative film or digital light valve and camera lens is formed, wherein:
Described light source is a face paroxysm optical diode led array light source;
The light that described paroxysm optical diode led array light source sent by its numerical control regulating system control carries out being radiated on egative film or the digital light valve after mixed light handles through light mixing device, then by camera lens to the printing paper imaging, the photo of enlarging and print out.
Wherein: this face paroxysm optical diode led array light source is divided into m * n unit area (m, n are natural number).
Each unit area of this face matrix LED array light source is rearranged in the plane according to a certain percentage by among three kinds of several red light emitting diodes LED, green LED LED and the blue LED LED one or more.
Described digital light valve is light valve devices such as colour or black and white transmission type LCD liquid crystal, LVT light valve, reflective LCOS liquid crystal light valve, LVT light valve.
Described device also comprises the LED digital-control circuit, links to each other with this face paroxysm optical diode led array light source.
Described device also comprises computer and Control Software, links to each other with this LED digital-control circuit.
After adopting such scheme, the utility model is not only applicable to enlarge and print based on the exposure of traditional egative film, and is applicable to based on the digital photo of digital light valve and enlarges and print, and its beneficial effect that has is summarized as follows:
1, the color representation power of photo imaging is strong
Because adopt the LED light emitting diode of pure color to replace the white light Halogen lamp LED, the RGB monochromatic light that sends has increased substantially the excitation of imaging spectral as the light source of enlarged color photograph, thereby has significantly improved the color representation power of photo imaging.
2, power consumption is little, stability is strong
Because be more than 50,000 hours the serviceable life of LED light emitting diode, so the life-span is longer, power saving more, thereby improved the quality of stability of enlarging and print.
3, the efficient height of enlarging and print
Because this device has been eliminated color filter system and mechanical shutter, thereby has increased the probability of failure of system, has reduced cost, thereby has increased substantially the efficient of enlarging and print.
4, photo image quality height
Because the luminosity of LED can be controlled separately by software, thus can be by the luminous intensity of software and digital-control circuit independent regulation plane of exposure arbitrary region, thus improved the image quality of photo.
Introduce the utility model in detail below in conjunction with description of drawings and specific implementation.
