Description
Technical field
The utility model belongs to stage and landscape lamp lighting area, more particularly to water wave lamp optical system field.
Background technique
Using more and more extensive, the place of application is also more and more, sometimes needs in modern society's stage lamp market
It allows lamps and lanterns to get to generation light-illuminating effect on building, plays the role of the beautification to scenery and set off atmosphere by contrast, existing market
The upper less water wave lamp with watermark pattern effect, this water wave lamp with watermark pattern effect can irradiate the effect of flowing water
Fruit, as smart as a new pin, beautiful.The water wave effect of water wave lamp has following several manifestation modes currently on the market.
The first is the rotation by watermark pattern roller to realize.Such as the utility model of Publication No. CN206093600U
A kind of New LED water wave lamp of patent, mentioned in the summary of the invention second segment of its specification " fixed rotating shaft across motor connect
Connect the left end that end socket is mounted on pattern pipe；The right end of the pattern pipe is equipped with rotating bracket, the left end installation of rotating bracket

For another example a kind of water wave lamp of the utility model patent of Publication No. CN207262094U, at the 4th section of specific embodiment party of its specification
In mention " the water wave roller 5 connect driving assembly be installed on being able to rotate in the lamp housing 1 ", can be seen by above-mentioned, two kinds
Scheme get water wave effect be by pattern pipe perhaps the rotation of water wave roller 5 and pattern pipe or water wave roller have multiple engrave
Empty watermark pattern hole, i.e., what its image-forming principle was taken is that light directly transmits pinhole imaging system, then by rotation, reaches the water of 2D
Line flow effect.
Second is that the rotation of watermark pattern disk is leaned on to realize, for principle, i.e., illumination is mapped on watermark pattern disk so
Direct projection imaging is similar to watermark pattern afterwards, and flowing water effect is then reached by the rotation of watermark pattern disk.Such as publication number
For a kind of water wave lamp of utility model patent of CN205807269U, " the water is mentioned in the specific embodiment of specification
It is coated with patterned coatings on line pattern disk 9 or is carved with pattern form, specifically, the pattern that can be water wave is either other
Pattern formation, the watermark pattern disk 9 being rotated by the driving device 6.Since the bottom in light source is provided with
Driving device, and it is provided with watermark pattern disk on the top of light source, it is rotated using driving device driving watermark pattern disk, in light
In the case that source shines, due to the pattern effect on watermark pattern disk, so that the light issued is imitated with dynamic shadow
Fruit.", from the foregoing, it can be seen that, water wave effect is the imaging of simple light projection watermark pattern disk, such water wave effect have one it is non-
Often big limitation, is exactly that edge is very clear, that is, is imaged as a disk, have multiple similar water waves in disk, in water wave figure
In the case that case disk rotates, water wave generates the simulation flowing water effect of rotation 2D.
The third is other effect disks of being arranged in pairs or groups by watermark pattern disk, such as public to reach relatively good water wave effect
The number of opening is the patent of invention of CN103574481A, mentions " be mounted with that water waves lamp before the lights, when needing water in the description
When line light efficiency, LED light source 2 provides light after being powered, and does efficient secondary light-distribution by secondary light-distribution lens 3, is irradiated to
Color chips disk 6, color chips filter color, and light has penetrated color chips disk 6 and obtained being imitated by effect glass line piece 7 after the effect of polychrome
Light after fruit is radiated in multi-panel transparent prism 8, and the light efficiency reflected away just achievees the effect that water wave.", from the foregoing, it can be seen that, this
Scheme is above on the basis of second of scheme, and a transparent prism 8, the effect reached or simple is simply added
Reach the water wave effect of 2D by water wave rotation.
In addition, passing through retrieval, it was found that a kind of some other patent documents of water wave effect:
Such as the utility model patent of Publication No. CN202196254U, mentioned " as shown projector, only in specification
28, volume switch 29 need to be turned on the switch, then waves projection lens i.e. cuboid 10 in wabbler mechanism 16, the biography of deceleration mechanism 18
Make swing and left and right play under dynamic, because fixed projection lens 9, waving projection lens i.e. cuboid 10 and having just like wave
The male and fomale(M&F) of the clear water surface of light, so the picture shown out can release wave in loudspeaker 4 at the same time like lumpy ocean
Voice of Waves." from the foregoing, it can be seen that, the generation being previously mentioned in document is by vibration and sway projection lens like lumpy ocean
What head was cuboid 10 to realize, it is to be understood that it waves projection lens and is equivalent to second described in document above
Watermark pattern disk 9 in kind scheme or the effect glass line piece 7 in the third scheme, the only driving method of difference is not
Together, substantially or 2D water wave effect.
Above scheme can not develop how by optical system to generate a kind of 3D water wave effect more true to nature
Scheme, in daily life, the principle for the 3D film that we are seen is as follows:
With two camera lens filming apparatus as human eye, the double vision point image of lower scenery is shot.Pass through two projections again
Machine shows the image synchronization of two viewpoints, is shown in this slightly differentiated two images in screen, at this moment if using eyes
Direct viewing, it is seen that picture be overlapping, some are smudgy, to see stereopsis it is necessary to take measures, make left eye only
See left image, right eye only sees right image.After the light projected from projector is by polarizing film, just at polarised light, left and right two
The polarization direction of polarizing film before frame projector is orthogonal, thus the polarization direction of the two beam polarised lights generated is also hung down mutually
Directly, spectators are watched using the polarising glass of corresponding above-mentioned polarised light, i.e., left eye can only see the picture that left machine mirrors, and right eye is only
It can see the picture that right machine mirrors, thus can be appreciated that three-dimensional scene, here it is the principles of three-dimensional film.
So how similarly to reach the 3D effect of water wave flowing using optical principle is that this technology will solve the problems, such as,
First some well known optics nouns are explained herein, luminous intensity abbreviation light intensity, international unit is candela(candela)
Cd is write a Chinese character in simplified form, the occasion that luminous intensity is for point light source or the size of illuminator is smaller compared with irradiation distance.
This amount is to show illuminator in the aggregate capabilities of spatial emission, it may be said that luminous intensity just depicts light source to be had on earth
It is mostly bright.Above-mentioned reference is from Baidupedia.
A kind of phenomenon is appreciated that by above and daily life, if 1 point light source is imaged as A, A on an imaging surface
It is divided into two regions a1, a0,
Original state S1:a1 is the high region of light intensity, and a0 is the low region of light intensity, and the light intensity difference of a1 and a0 is very big,
So human eye can feel bright/a0 dark obvious visual difference of a1；
For transition state S2:a1, a0 light intensity with original state S1 on the contrary, i.e. a1 is the low region of light intensity, a0 is that light intensity is high
Region, and the light intensity difference of a1 and a0 is very big, then human eye can feel dark/a0 bright obvious visual difference of a1；
It is understood that then human eye can generate the jump of brightness when being switched to transition state S2 from original state S1 as A
Jump visual impression, and light intensity difference is more obvious more greatly；And when this S1 process for being switched to S2 constantly repeats, then human eye can generate 2D
The visual impression of brightness jump.
If by experiment it is found that do not seen simultaneously experiment but it is understood that, when 1 point light source one be imaged
At two pictures of A, B on face, and the characteristic of A, B are the same, when the superposition of A, B picture and when continuous repetition S1 is switched to the process of S2 simultaneously,
Then human eye is the luminance fluctuation effect that can generate 3D.
By above-mentioned, it is to be understood that this optical system is technically characterized in that 1- point light source；2- is in the same imaging surface
At 2 pictures；The each picture of 3- is made of the very big each region of light intensity difference；4- the same area light intensity difference continuously changes.
In a kind of dynamic light projecting apparatus of patent of invention of Publication No. CN105066058B, mention in the literature
" light emitting angle of the LED light source is 180 °；The LED light source length and width and the swing light transmitting sheet and fixed light transmission
The ratio of the focal length of piece is 1:30, the focal length for swinging light transmitting sheet and fixed light transmitting sheet and the aluminum substrate and the swing
The ratio of the distance between light transmitting sheet D1 is 3:2, the focal length for swinging light transmitting sheet and fixed light transmitting sheet and the aluminum substrate and
The ratio of the distance D2 of the fixed light transmitting sheet is 1:1 ", it is also mentioned that " monochromatic or polychrome light is provided by LED light source 2, it can
With the color of various colors of sunshine and demand, luminescence law meets 180 degree lambertian and shines, and axial intensity is maximum, other party
Decay to according to axial cosine angle.Light distribution becomes multidirectional after swinging the free form surface of light transmitting sheet 3, does not wait light
By force.Light distribution becomes multidirectional after the free form surface of fixed light transmitting sheet 4, and high contrast light distribution, partial region is bright area, part
Region is dark areas.Due to the movement of free form surface, bright area is constantly moved, the bright area difference moved further that different LED are generated
Form " wind-force brush under dynamic water surface reflected sunlight to by according to object, water ripples intersection is rippled, and shadow is mottled " effect
Fruit." from the above, it is seen that it realizes that " effect of 1- point light source " is by LED light source length and width and the swing light transmitting sheet
Ratio with the focal length of fixed light transmitting sheet is 1:30, this ratio is obviously excessive, seriously increases the length of lamps and lanterns；In addition its light
It is to be directly over to swing light transmitting sheet and fixed light transmitting sheet, the light intensity difference of bright dark areas out is how many, is not also illustrated,
I.e. it is realized in the technical parameter of " each picture of 3- is made of the very big each region of light intensity difference ", optical principle and actual effect
It is insufficient disclosure.

65.7mm.In position of optical element range data, compared with the patent of invention of Publication No. CN105066058B, because of its document
In be described as " the LED light source length and width and the ratio of the focal length for swinging light transmitting sheet and fixed light transmitting sheet are 1:30,
The focal length for swinging light transmitting sheet and fixed light transmitting sheet and the aluminum substrate and the ratio for swinging the distance between light transmitting sheet D1
Example is 3:2, the focal length and the aluminum substrate and the fixed light transmitting sheet distance D2 for swinging light transmitting sheet and fixed light transmitting sheet
Ratio be 1:1；", that is, assume its LED light source (4mm*4mm) for using this programme the same, then D1=4*20=80mm, D2=4*30
=120mm, it is clear that its optical system the space occupied is considerably beyond the utility model, i.e., its occupied lamps and lanterns space is remote
Much larger than the difference that the essential reason of the technical program, and the two difference is optical design scheme.
In technical solution described in the utility model, the process for generating water wave 3D fluctuation effect is described in detail as follows.
Embodiment one, as free form surface planoconvex lens A(3) moved in its plane, free form surface planoconvex lens B(4) it is solid
When fixed motionless:
The light that 1-LED light source (11) issues passes through collector lens group (12), and angled 45 ° -110 ° of the light of convergence adds
The purpose for entering collector lens group (12) is to improve the utilization rate of light source.
2- enters to inject dispersion lens (2) from the light that collector lens group (12) is emitted, due to being on one side on dispersion lens (2)
Plane, another side include several different irregular terrace with edges (21) of height, and terrace with edge (21) height H be 0.2mm≤H≤
1.4mm, therefore will form the non-linear light of dispersion shape when incident ray outgoing, and the light of the terrace with edge (21) by different height
It is poor by force to have notable difference.As attached drawing 8 be dispersion lens (2) terrace with edge (21) height H=0.2mm when SIMULATED SCATTERING light intensity
Curve, largest light intensity=3128.5cd；SIMULATED SCATTERING light when attached drawing 9 is terrace with edge (21) height H=1.4mm of dispersion lens (2)
Strong curve, largest light intensity=1826.0cd；It can be seen that the maximum light-intensity difference of the two reaches 3128.5/1826.0=1.7 times；By terrace with edge
(21) highly it is arranged to different purposes to be, increases the light intensity difference of light, in order to forms bright dark comparison when imaging
The region become apparent, while the region that light is imaged after light-radiating lens (2) is bigger, it is excessively sharp keen to avoid hot spot boundary
Problem.
3- is incident on free form surface planoconvex lens A(3 from the light that dispersion lens (2) are emitted), due to free form surface plano-convex
Eyeglass A(3) it is plane on one side, in addition one side includes the free-form surface lens c(5 of multiple strips), and free-form surface lens c
(5) projected outline is in water wave shape, and free-form surface lens c(5) it be radius of curvature R is -25mm ~ 25mm, form positive negative lens effect
It answers, when in order to be imaged on same imaging surface, is capable of forming the region that bright dark comparison becomes apparent；And it is arranged into an array from
By toroidal lens c(5), then shape multiple light and dark pictures arranged into an array.It, can at this time if be directly imaged on imaging surface
To see the hot spot for including multiple light and dark watermark patterns, and the effect due to dissipating scattered eyeglass (2) on imaging surface, this
Hot spot edge is the natural transition of virtualization, rather than sharp keen obviously has boundary sense.
4- is incident on free form surface planoconvex lens B(4 from the light that free form surface planoconvex lens A(3) is emitted), due to freedom
Curved surface planoconvex lens B(4) it is plane on one side, in addition one side includes the free-form surface lens c(5 of several strips), institute
State several free-form surface lens c(5) it is arranged in array；It is understood that light is incident on free form surface planoconvex lens B
(4) on, imaging principle be similar to the above process 3, be formed by equally be multiple light and dark watermark patterns hot spot,
Finally formed hot spot is that light passes through free form surface planoconvex lens A(3 respectively at this time) and free form surface planoconvex lens B(4) at
The superposition of picture, simulation hot spot as shown in Fig. 10.
5- is as free form surface planoconvex lens A(3) when being moved in its plane, light passes through free form surface planoconvex lens A(3)
Movement can be followed by being formed by multiple light and dark watermark patterns, be similar to light individually in free form surface planoconvex lens B
(4) the light and dark watermark pattern of the fixation formed will do it superposition, can be appreciated that the effect of the compound variation of continuous light and shade at this time
The hot spot effect that fruit, the i.e. 3D of watermark pattern rise and fall, essence is the watermark pattern different zones light intensity difference of array on imaging surface
The effect of consecutive variations carries out illuminance point by the direction XY of reference of cross hairs in scheming to simulation hot spot as shown in Fig. 11
Analysis, it can be seen that the variation that apparent height rises and falls is presented in the illuminance in Y-direction, in the background technique of the utility model
Describe this phenomenon；For the ease of more intuitively understanding, provided at the same time such as attached drawing 12, the conventional hot spot of simulation shown in 13
1 and simulate the illumination curve line chart of conventional hot spot 2, hence it is evident that it is seen that, conventional hot spot 1 and conventional hot spot 2 are with cross hairs in scheming
For reference the direction XY illumination curve present be normal distribution Gaussian curve.
Embodiment two, as free form surface planoconvex lens B(4) moved in its plane, free form surface planoconvex lens A(3) it is solid
When fixed motionless:
It is understood that be in embodiment two and one optical principle of embodiment it is identical, difference be only light pass through
Free form surface planoconvex lens A(3) be formed by multiple light and dark watermark patterns and pass through free form surface planoconvex lens B(4)
The stacked system for being formed by multiple light and dark watermark patterns is not identical, i.e. the formal not phase that the 3D of watermark pattern rises and falls
Together.
In addition, because free-form surface lens c is in free form surface planoconvex lens A(3) and free form surface planoconvex lens B(4) on
Array arrangement can be it is identical or different；It is understood that its final difference on effect is similarly water
The 3D of line pattern rises and falls not identical in form, is identical in optical principle.
Preferably, free form surface planoconvex lens A(3) and free form surface planoconvex lens B(4) spacing L be 10mm≤L
