The utility model is characterized in that light generated by light emitting diodes is introduced in optical fibers after the light is aggregated by lenses, the light derived by the optical fibers can be aggregated through another lens to be projected on sensitive materials to realize sensitization, and a plurality of light emitting diodes, a plurality of optical fibers and a plurality of lenses can be ranged in an array way according to requirements to realize the requirements of a plurality of pixel point image formation and large surface digital color enlarger color picture print expansion.
Description
Affiliated technical field
The utility model relates to a kind of imaging device of digital color enlargement machine electric light conversion, the fiber optic conduction LED digital color enlargement machine imaging device that especially carries out the electric light conversion.
Background technology
At present, known digital color enlargement machine imaging device, form by light source, LCD screen, camera lens, drives LCD screen shows digital image, camera lens will be realized the imaging of digital color enlargement machine electric light conversion by the image projection on the LCD screen of light illumination to photosensitive material, but LCD screen manufacturing process complexity, effective pixel points is less, can not be applied in the large format digital color photo enlarging-printing equipment.
Summary of the invention
In order to overcome the few deficiency of effective pixel points, the utility model provides a kind of fiber optic conduction LED digital color enlargement machine imaging device, and not only manufacturing process is simple for it, and can increase the quantity of effective pixel points as required.
The technical scheme that the utility model technical solution problem is adopted is:
The drives lumination of light emitting diode, show digital image information, between light emitting diode and optical fiber, be provided with lens A, after the light that lens A sends light emitting diode is assembled, introduce in the optical fiber, the ray cast that optical fiber is derived to photosensitive material sensitization, on photosensitive material, is finished imaging with image information recording to the photosensitive material.Between optical fiber and photosensitive material, can be provided with lens B, make that to project on the photosensitive material luminous point littler.More than being that pixel is monochromatic constitutes, and light emitting diode drives can be by D/A conversion and control luminous intensity or by logical circuit control fluorescent lifetime, the picture point of record different densities value on photosensitive material, if recording colour density, available Tricolor LED.As required, a plurality of diodes can be arranged in order and are integrated on the circuit board, also by same series arrangement and be integrated on the lens board, for easy for installation, optical fiber can be fixed on the support, the arrangement of the arrangement fit lens of optical fiber with a plurality of lens.In order to improve image taking speed, photosensitive material end optical fiber can be divided many rows arrange, orientation is vertical with the photosensitive material moving direction.The quantity that every row arranges is determined according to photosensitive material breadth extreme and resolution.
The beneficial effects of the utility model are: the imaging device of how much forming digital color enlargement machine electric light conversion of pixel on demand, production technology is simple simultaneously, can be applied to the large format digital color enlargement machine, satisfies the requirement of the large format digital photograph of enlarging and print.

Embodiment
In Fig. 1, light emitting diode (1) sends the light of digital image information, after lens A (2) assembles, imports optical fiber (3), conducts the irradiate light that and go up sensitization to photosensitive material (5) from optical fiber (3).In order to improve imaging precision, can between photosensitive material (5) and optical fiber (3), lens B (4) be set.In Fig. 2, in order to make mounting process simple, directly light emitting diode (1) is fixed on the drive circuit board (6), being designed to 64 Tricolor LEDs (1) is to constitute driving and modularization in order to be fit to piece of CPLD, and the quantity that increases module can increase picture point quantity.Among Fig. 3, the arrangement of lens A (2) cooperates the arrangement of light emitting diode (1) among Fig. 2, in order to arrange conveniently, one block array lens board A (7) can be set, lens A (2) is fixed on the lens board A (7), installs for convenience, can structure of fiber_optic (8) be set in optical fiber end.Lens can adopt ripe manufacturing process, as: lenticule processing mode or injection moulding mode are made integral body with lens and lens board.Among Fig. 4, optical fiber (3) is fixed on the support (8), and optical fiber (3) other end receives the light of lens A (2) among Fig. 3, and this end arrives ray cast on the photosensitive material (5).Photosensitive material can be close to fiber end face.Among Fig. 5, project the size of luminous point on the photosensitive material, between optical fiber and photosensitive material, designed lens B (4) for dwindling optical fiber.
The last lens B (4) of lens array plate B (9) dwindles luminous point among present embodiment Fig. 5, make on the photosensitive material picture point less than profile of optic fibre, picture point is increased at interval, the displacement and optical fiber (3) vertical direction that can be designed to photosensitive material (5) per step are the distance of a sensitization picture point size for this reason, it is the distance of a sensitization picture point size that the displacement in optical fiber (3) per step can be designed to optical fiber (3) horizontal direction, make that the sensitization picture point completely covers on the photosensitive material, in order to improve photosensitive imaging efficient, optical fiber (3) on the structure of fiber_optic (8) can be arranged as many rows, every row's optical fiber dislocation is arranged, its dislocation displacement can be designed to luminous point and dwindle after image point size spacing, optical fiber among Fig. 5 (3) conducting light scioptics B (4) make the light-sensitive image spot diameter dwindle three times after assembling, then enroll two row's optical fiber, making every row's optical fiber dislocation displacement is 1/3 of former optical fiber spacing.
