Description
Technical field
This utility model relates to a kind of lamp optical system, is specifically related to a kind of based on fresnel lens array LED intelligent illumination optical system.
Background technology
Along with developing rapidly and society continuous progressive of LED and information technology, people to illumination efficiently control and the requirement of functional diversities also improves constantly, LED intelligent illumination system is arisen at the historic moment.Intelligent illuminating system makes full use of electronic technology, communication technology and computer networking technology and is organically linked together by the various ligthing paraphernalias in building, it is achieved effective management and control.
LED intelligent illumination is controlled in certain area mostly at present, regulates colour temperature, brightness, and is furnished with fine motion sensing, bluetooth, infrared or WIFI communication equipment.As needed increase machinery or install multiple light fixture to feasible region illumination, to realize the purpose controlling to specify illumination region.Meanwhile, lighting only realizes specifying the brightening function in region, renders or picture and animation shows if carrying out atmosphere, needs to increase additionally other projector equipment, this just bring cost increase, the series of problems such as installation inconvenience, the wasting of resources.
Lens arra has been applied in Projection Display, but lens sizes is smaller, belongs to microlens array, the DMD (DMD) developed such as Texas Instrument (TI), and lens dimension is about at ten several microns.This type of digital micro-mirror is only applicable to display, and may not apply to illumination, and cost is the highest.
Fresnel Lenses has been widely used for the fields such as optically focused cumulative, infrared acquisition, automotive lighting.Fresnel Lenses has the biggest advantage in large scale scope, compared with traditional lens, Fresnel Lenses has identical optical property, and thickness can be accomplished the thinnest simultaneously, and the maturation process of Fresnel Lenses compression molding makes it to produce in batches, greatly reduces the cost of product.
Utility model content
This utility model utilizes and controls LED array, coordinate the lens arra of coupling, realize the subregion illumination of light, the Projection Display of character and picture can also be realized simultaneously, Intelligent partition illumination is combined with Projection Display, solve traditional illumination system with this and control inconvenience, the problem that motility is the strongest.
This utility model adopts the technical scheme that: a kind of based on fresnel lens array LED intelligent illumination optical system, it includes LED light source, diffuser plate and lens arra, described diffuser plate and lens arra are sequentially arranged in the light path of LED light source, LED in described LED light source is equidistantly distributed, described lens arra is made up of Fresnel Lenses arranged distribution, and between each Fresnel Lenses, spacing is equal.
Described LED light source uses the three-in-one lamp bead of RGB.
Described LED arrangement is rectangular array.
Described lens arra is rectangular array, and its lens number is 64 and 8*8 and equidistantly arranges.
Described diffuser plate uses the PMMA plate of high transmission rate.
The beneficial effects of the utility model are: this utility model exports using LED array as light source, by controlling the LED lamp bead of correspondence position, design the lens arra of coupling, it is achieved different illuminating effects.Whole LED lamp bead are lit up as white light, it is achieved integral illumination effect；Partial LED lamp bead is lit up as white light, it is achieved specify area illumination；Correspondence partial LED is lit up as colourama, it is achieved character, graphic pattern projection show；By the dynamic video signal after LED input conversion, it is achieved the Projection Display of animated video.
It addition, the emergent ray of LED is by after diffuser plate, can become is more uniform, eliminates the dazzle of integral illumination and area illumination, makes the character picture of display and animated video softer simultaneously.The design of lens arra adds so that common illumination path changes, by refraction of light path and the combination of integral array of lens unit, it is achieved the rectangular area illumination specified, it is also possible to realize the Projection Display of character pattern and animation.

Detailed description of the invention
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, a kind of based on fresnel lens array LED intelligent illumination optical system, it includes LED light source 101, diffuser plate 102 and lens arra 103, described diffuser plate 102 and lens arra 103 are sequentially arranged in the light path of LED light source 101, LED in described LED light source 101 is equidistantly distributed, and described lens arra 103 is made up of Fresnel Lenses arranged distribution, and between each Fresnel Lenses, spacing is equal.
Wherein, described LED light source 101 uses the three-in-one lamp bead of RGB, described LED arrangement to be rectangular array.Described lens arra is rectangular array, and its lens number is 64 and 8*8 and equidistantly arranges.Described diffuser plate uses the PMMA plate of high transmission rate, it is achieved go out the homogenization of light.
As shown in Figures 5 to 7, after LED light source 101 receives control signal, light the LED of corresponding region, including its brightness, color and gray value etc., after the even light of diffuser plate 102, inciding lens arra 103, lens arra 103 carries out beam shaping to light, finally obtains illumination region or the pattern wanted at projection surface 104.
Realize integral illumination: LED light source 101 all lights up as white light, do dodging through diffuser plate 102, then after lens arra 103 reflects, arrive projection surface 104, illuminate whole projection surface 104, reach general integral illumination effect with this.
Feasible region illuminates: part LED light source 101 lights up as white light, does dodging through diffuser plate 102, and through Fresnel Lenses, light path launches deviation, and projection lighting is to different regions respectively.As lighted position LED shown in 501, finally obtain the upper right corner shown in 502 and illumination region, two, the lower left corner at projection surface 104.
Realize character projection: light position LED shown in 601, finally obtain the character pattern shown in 602 at projection surface 104.
This utility model is not directed to part and the most same as the prior art prior art maybe can be used to be realized.
