Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further.
Embodiment one
Shown in composition graphs 1 to Fig. 4, a kind of dynamic optical grenade instrumentation, it comprises housing 10, swings light transmission piece 3, fixes light transmission piece 4, light source assembly and driving mechanism.Described housing 10 is provided with a light-emitting window 5.Light-emitting window 5 is square.Described light-emitting window 5 is provided with the darkening ring (figure does not look) of light leakage.
The light that light source assembly sends projects the outside of housing 10 successively by swinging light transmission piece 3, fixing light transmission piece 4 and light-emitting window 5.Described light source assembly comprises aluminium base 1 and is welded at least one LEDs light source 2 on aluminium base 1.Described LED light source 2 comprises monochromatic LED lamp pearl, or the LED lamp bead that many colors are different.Multichannel drives, and is divided into white 1700-8000K, simulates the light quality sense of the different sunlight among a day.Light green color 560nm, be irradiated in green water for simulating sunlight, photochromic by the color to a certain degree changed, the reflection that the inclined cyan of cyan simulation sunlight is later, amber 595nm can simulate amber sunlight at dusk, sunlight time blue 460nm simulation is the most blue, multiple color can independently present and simulate the water-jet light under different condition separately.The lighting angle of described LED light source 2 is 180 °.LED light source 2 is as far as possible near the center of optics, and can maintain a certain distance between LED light source 2, the light of different LED light source 2 embodies differentiation over time and space in identical light path, further increases quantity and the direction of motion of in hot spot bright, adds hot spot intension.
Fixing light transmission piece 4, light source assembly and driving mechanism are all fixedly mounted in housing 10.
Described driving mechanism is for driving the swing swinging light transmission piece 3 and continue.Concrete, described driving mechanism comprises stepper motor 8, interlock dish 7, gangbar 6 and constraint slide rail (figure does not look), one end of gangbar 6 is fixedly connected with swing light transmission piece 3, the other end of gangbar 6 is fixedly connected with interlock dish 7, and the output shaft 9 of stepper motor 8 is fixedly connected with interlock dish 7.Described constraint slide rail, for when stepper motor 8 works, makes swing light transmission piece 3 along elliptical orbit continual reciprocation.
Wherein, swing light transmission piece 3 and fixing light transmission piece 4 are formed by free form surface array.Described free form surface array is the transparent oval planoconvex spotlight array that multiaspect rounding off is connected.Described multiaspect is at least 30.Swing light transmission piece 3 different with the structure of the free form surface array of fixing light transmission piece 4.
The projection of periphery in fixing light transmission piece 4 of light-emitting window 5 overlaps with the periphery of described fixing light transmission piece 4, or is positioned at the periphery scope of described fixing light transmission piece 4; The projection of periphery in swing light transmission piece 3 of fixing light transmission piece 4 is positioned at the periphery scope of described swing light transmission piece 3.
The difference maintained a certain distance between D1 (aluminium base 1 and swing are through the distance between sheet 3) and D2 (distance between aluminium base 1 and fixing light transmission piece 4), prevent from swinging light transmission piece 3 and fixing light transmission piece 4 generation collision, this range difference is also the demand of optics simultaneously.
D3 is length and the width of square light-emitting window 5 design, and square exiting surface meets the light path of the present embodiment more than circular exiting surface, and this D3 length and width regions are transparent region, and other regions are light tight, avoid light leak.
The free form surface surface swung through sheet 3 needs to adjust according to the size of LED light-emitting area, under the LED light source 2 (i.e. LED chip) of 1mm length and width, the focus design swung through the free form surface of sheet 3 and fixing light transmission piece 4 is about 30mm, accordingly under combined lens, D1 is about 20mm, and D2 is about 30mm.
Under the LED chip of 5mm length and width, the focus design swinging the free form surface of light transmission piece 3 is about 150mm.Accordingly under combined lens, D1 is about 100mm, and D2 is about 150mm.
Other LED sizes proportionally calculate.
The operation principle of the present embodiment:
There is provided monochromatic or the light of polychrome by LED light source 2, can the color of various color of sunshine and demand, it is luminous that luminescence law meets 180 degree of lambertian, and axial intensity is maximum, decays according to the cosine angle with axis in other directions.
After swinging the free form surface of light transmission piece 3, luminous intensity distribution becomes multidirectional, not isocandela.
After the free form surface of fixing light transmission piece 4, luminous intensity distribution becomes multidirectional, high-contrast luminous intensity distribution, and subregion is bright area, and subregion is dark areas.Due to the movement of free form surface, bright area is movement constantly, the effect that the asynchronous movement of bright area that different LED produces defines " wind-force brushes lower dynamic water surface reflected sunlight to by photograph thing, and water ripples intersection is rippled, and shadow is mottled ".
In order to further stiffening effect, stepper motor 8 can forward, reverse rotation, can at a slow speed, can be quick, the change can simulating the wind-force brushing the water surface on the impact of the sunshine of reflection, use other at a slow speed uniform speed electric motor also can export the stable light efficiency of single.
The object of the present embodiment is the pursuit meeting people, the selection of light source adopts planar package monochrome or many color LED light sources 2, and light path components and parts adopt free form surface components and parts, shorter and rational optical axis design, can be designed in the shell of waterproof easily, be used in open air.
Dynamic water surface reflected sunlight under water-jet optical analog wind-force brushes is to being subject to according to thing, water ripples intersection is rippled, shadow is mottled, change incomparably, rub fragrant lane shadow, water-jet light theory optical effect and natural optical effect are identical, and have reappeared the unique beautiful scenery just can seen in particular circumstances in the daytime, have reappeared the artistic conception of " dream enters cigarette water route, the south of the River ".
The present embodiment applied nonlinear optics imaging technique, its hot spot is made up of the bright position of small part and most shade, and hot spot angle is moderate, and contrast is high, sliceable, can be quiet, and movably, speed can be fast or slow.
Embodiment two
As shown in Figure 5, the present embodiment and the difference of embodiment one are that the movement locus swinging light transmission piece 3 is different.Specifically, described constraint slide rail, for when stepper motor works, makes swing light transmission piece along elliptical orbit or straight path continual reciprocation.
The utility model is irradiated to the image that water body reflexes to trees and building not having the local solar simulated of water, its definition random intersection ripples, and contrast is higher, optical grains, the different wind blows waters surface reaches different light efficiency speed, this natural process of this light path real simulation.
For a person skilled in the art, according to technical scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the utility model claim.
