The specific embodiment
Below in conjunction with the accompanying drawing among the present invention, the technical scheme among the present invention is clearly and completely described.
Please refer to Fig. 1-5, one of them embodiment of Solid Double light source module of the present invention comprises directional plane illuminator 10 and LED shot-light 20, and described directional plane illuminator 10 comprises OLED illumination panel 11 and is arranged on the flat thread lens 12 of OLED illumination panel 11 fronts.Flat thread lens 12 can be used as independently that optics is that OLED illumination panel 11 carries out secondary light-distribution, the plane transparent substrates that also can be used as OLED illumination panel 11 directly and the OLED processing procedure be packaged together.Concrete, described flat thread lens 12 can be stacked with OLED illumination panel 11 and install and use, also can be with the plane of flat thread lens 12 printing opacity carrier (or microlens array (the Microlens Array as OLED illumination panel 11, MLA) film) with the encapsulation of OLED illumination panel 11 one processing procedures, as the optical module of the directed light projector of the present invention.
Please refer to Fig. 3, OLED illumination panel 11 and 12 combinations of flat thread lens, can expand the range of application of OLED planar light source, can the directed light extraction efficiency that strengthens OLED, diffusion diffused light collimation is assembled, adjust boil down to and have direction-sense planar light source, the cold light that can be used for the high brightness high-color rendering does not have shadow flood lighting device.
Concrete, OLED illumination panel 11 is matrix distribution formula (grid is netted) self-luminous surface light sources that a kind of Organic Light Emitting Diode is formed, the luminous diffusion diffused light that is of OLED, the half-wave peak width of spectrum is very wide, there is not bigger breach in the OLED luminescent spectrum of white light, it is the scope that can contain whole visible lights in the white light, colour temperature 3500～6500K is omnidistance adjustable in from warm colour to the cool colour scope, this makes that OLED lighting source color representation power is very abundant, has good chromaticity coordinates or excellent colour rendering.Has very large light-emitting area based on OLED matrix fraction cloth structure, whole surperficial every bit all can send the soft uniform light of nature, compare with other light source and to have incomparable functionality advantage, as the soft free from glare of light, spectral width colour temperature adjustable brightness, the flexible flexible of flat thin, do not have the environmental protection of injury ray, driving voltage is low and various advantages such as light but not heats.Therefore OLED itself almost is exactly an efficient desirable flat illumination light source, and need not arrange in pairs or groups diffuser plate, LGP or lampshade can directly use as lighting.
OLED planar light angle of visibility extensively reaches 170 degree, and illumination has the light efficiency advantage that is showing very much as routine.If be used for directed light projector, light beam just seem concentrate inadequately and relative point relatively poor, its projection light efficiency can be had a greatly reduced quality, and has limited this good light source on the contrary in the practice in some field.Obviously light is the OLED illumination panel of diffusion diffused, is difficult for being directly used in the illumination operation with directed light projector character.Therefore, the present invention increases a kind of directed convergent lens (being flat thread lens 12) for OLED illumination panel 11, adjustment compression by 12 pairs of light of flat thread lens, light with OLED illumination panel 11 diffusion diffused planar light sources, focus on or collimation through flat thread lens 12 secondary reshaping, strengthen quantum extraction efficiency outside the OLED, improve emitting brightness, and compress the visual field in one direction, formation has the directional plane light source that lofty tone is directed, be easy to the shaping of projection hot spot and control.
Described OLED illumination panel 11 and the described flat thread lens 12 coaxial shot-light installing holes 13 that offer, described shot-light installing hole 13 is used for installing LED shot-light 20.Please refer to Fig. 4, described LED shot-light 20 comprises columned shot-light shell 21, in the described shot-light shell 21 by after LED lamp 22, adjustable aperture 23, lens 25 are installed forward successively, adjustable aperture 23 is connected with hot spot regulating handle 24.Described shot-light installing hole 13 can be inlayed or be installed on the described columned shot-light shell 21.
Described flat thread lens 12 claim that again (English: Fresnel lens), be a kind of optical module of sheet thin type, be annotate to press the thin slice that forms (thickness＜1mm) by polyolefine material to Fresnel lens.Lens surface simultaneously is the light face, and another side (towards the one side of OLED illumination panel 11) has been scribed ascending concentric circles.From section, its surface is made up of a series of sawtooth pattern grooves, and core is the ellipse camber line.The texture of sawtooth pattern is according to interference of light, disturbs and penetrate and receive and dispatch the claimed range that angle form to focus on and design.Angle institute is different between each groove part and the adjacent notches, but all concentrates a place to form gonglion light.Each groove part can be regarded as an independently lenslet, and light is adjusted to directional light or optically focused.Generally speaking, also can satisfy this directed flood lighting design for scheme requirement as long as there is a face to be made into serrated face in two faces of the incident of light and outgoing.
This flat thread lens 12 adopt in design and divide thick method, its objective is planar strength, the change in the wrong of reduction eyeglass that increases lens and obtain bigger bore, can also alleviate thickness and the weight of lens effectively.Because the minute surface center of flat thread lens 12 has shot-light installing hole 13 described in the present embodiment, can lose the most important light of core, lens are decomposed into the sawtooth pattern endless belt of several different curvature, the jaggy pitch of diverse location or distance are different as required in same lens, can adjust tooth pitch, curvature, duty and recently change the path of light to remedy the disappearance in OLED center light district, make convergence of rays by each endless belt on same picture point, spherical aberration corrector also can moderately improve aberration simultaneously to a certain extent.
Because OLED illumination panel 11 lighting angles are big, the diffusion of light diffusion wide-angle, its matrix distribution formula ray structure is equivalent to the OLED light-emitting area numerous light source (OLED is not spot light) that distributing.Take the logical light principle of flat thread lens 12 not consider the image quality of lens bright dipping basically, therefore do not do strict requirement for the aberration of flat thread lens 12, the definition of light spot profile.Utilize ray tracing to compress the visual field in one direction, can be preferably with the planar light source of the OLED diffused of desirable matrix dense distribution formula, collimate to orthotype directional light or optically focused and strengthen its light projector brightness.Its principle is: diffusion light enters from a side, focuses on or penetrates with directional light at opposite side through flat thread lens 12.Flat thread lens 12 are typically designed to collimating mirror, as projection lens, condenser etc., this flat luminous body can provide hot spot scope and the even soft cloth light effect of a basic fixed, and the movable hot spot of LED spot light shot-light 20 adjustable size is included coaxially.
The action principle of flat thread lens 12 and flaky texture, with the incident ray optical alignment for having direction-sense plane light, compress the visual field in one direction and can orientation strengthen the coupling efficiency in oled light source, thereby increase the utilization rate that display brightness improves light, and formation meets light intensity spatial distribution required for the present invention.It acts on flood lighting, has bigger logical light face and less light loss, makes the transmitance of light more much higher than traditional convex lens.Especially: the laminar lens of large format, can cooperate OLED illumination panel effective area ratio and ultrathin design, this is very important to the no shadow degree that reduces the Weight-optimised fitting structure of lamp panel, enhancing visual field, is fit to system's luminous intensity distribution of the logical light in OLED illumination panel large aperture or directional lighting.
