Description

Novel water wave projection lamp

Technical Field

The invention relates to the technical field of stage or landscape lamps, in particular to a water wave projection lamp.

Background

Along with the development of society, people's quality of life is higher and higher, and in various environment occasions, people can use various lamps and lanterns to decorate the environment usually, decorate lamps and lanterns main function and be projected light on the wall of building for the building can show the effect that light shines evening, reaches the effect of setting off the atmosphere.

Diamond glass is glass with a plurality of granular three-dimensional polygons distributed on the surface, and because the granular three-dimensional polygons are similar to diamonds, the glass containing granular polygons is generally called diamond glass, and the detailed form of diamond glass refers to the glass net of china.

With the advent of diamond glass, many lamp manufacturers found that when light was shone on the diamond glass, because the diamond glass was covered with a plurality of uneven three-dimensional polygonal profiles, and a plurality of uneven three-dimensional polygonal profiles were simulated to be connected together under the effect of light, the stripe that can produce the similar ripple form of undulation, and made diamond glass into disc shape and become the ripple glass dish, then when carrying out the rotation, the light that the light source sent can produce through the rotation of diamond glass lens and throw out the effect that is similar to the ripple flow. Therefore, the diamond glass lens is more and more widely applied to the field of stage and landscape lamps, which are called as the water wave lamp.

"5A-first water wave glass" as described in patent publication No. CN207796894U, the specification thereof; 5B-second Water wave glass "is actually a diamond glass lens as described above. Meanwhile, the literature mentions that "from the above description, the beneficial effects of the present invention are: the utility model provides a can be with light gathering to carry out the water wave projection lamp who shelters from to stray light, the light of this shot-light has the light efficiency height, the even characteristics of transmission facula through gathering many times, owing to effectively sheltering from to stray light, makes the definition at water wave projection light spot center and edge unanimous, has solved the undulant serious problem of trailing of facula edge. ". Therefore, the water wave flowing effect formed by the diamond glass lens has a very large limitation that the outline of the edge of the disc is very clear, namely the disc is formed; meanwhile, the water wave is more similar to the effect of a slow flowing water wave, and does not have the effect of obvious wave fluctuation; in addition, the water wave projection lamp using diamond glass has water wave lines formed by the connection lines of a plurality of rugged three-dimensional polygonal outlines on the surface of the diamond glass, and the connection lines are different from the actual water wave lines.

Therefore, after the water wave lamp is applied to the field of stage and landscape lamps with the initial freshness, the relatively rough water wave effect of the water wave lamp cannot meet the requirement of the current society for finer and more beautiful effect of the stage or landscape lamps, so that the demand of the water wave lamp adopting the diamond glass lens is lower and lower, and even the water wave lamp gradually leaves the market.

The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

Before the embodiments of the present technical solution are described in detail, an imaging principle of the perturbation lens in the present technical solution is described first to facilitate understanding of the present technical solution. The imaging principle of the disturbance lens specifically refers to patent document CN110347006A, which describes that "this scheme can realize the projection effect of the static pattern showing dynamic fluctuation through an optical scheme, and it applies the classic geometric imaging principle and the human eye persistence principle, and changes the image plane distortion state through dynamic change, thereby changing the optical distortion of the local image plane and the similarity of the object image, and further realizing the picture dynamic effect of regular fluctuation while keeping the projection picture definition not lost. "the same thing of this document and this technical scheme is to have adopted the perturbation lens, but the overall scheme of this technique still exists very much differently, patent document CN110347006A is focused on 1-keep the projection plane change clear; 2, generating a picture dynamic effect of regular fluctuation through image surface distortion; namely, the main problem to be solved is the problem of pattern effect of the traditional pattern lamp, and the pattern of the traditional pattern lamp is relatively fixed; the technical scheme is characterized in that the laminated surge and the undulating effect in the sea are further expressed, namely when the problem that the definition of the center and the edge of a light spot is consistent due to a diamond glass lens of a traditional water wave lamp is solved, the undulating effect of the laminated surge is increased, so that the wood grain lens 4 with the surface similar to wood grains is selected, and the dynamic imaging effect is further intensified due to the rotation of the wood grain lens 4.

The first embodiment is as follows:

as shown in the attached drawing 1, the novel water wave projection lamp comprises a light source module 1, a first condensing lens 2, a wood grain lens 4 and an imaging lens group 5 which are sequentially arranged along the emergent direction of light rays, wherein a light screen 3 is arranged between the first condensing lens 2 and the wood grain lens 4, and a light through hole 31 is formed in the middle of the light screen 3.

The light source module 1 comprises a light source and a condenser lens group, the light source is an LED light source or a gas discharge light source or a laser light source, and the condenser lens group is a reflecting cup or a convex lens combination formed by combining a plurality of convex lenses. The condenser group is used for converging light rays emitted by the light source, so that the luminous efficiency is improved.

The light emitted by the light source module 1 passes through the first condensing lens 2, and the purpose of the light is to converge the light again before the light enters the light through hole 31, so that the light emitting efficiency is further improved, and the luminous flux is increased.

The light emitted from the first condenser lens 2 then passes through the light-passing hole 31 of the light-shielding plate 3, and the light-passing hole 31 is used for collecting light.

The light rays emerging from the through holes 31 are incident in turn on two wood-grain lenses 4, the two wood-grain lenses 4 being located on either side of the main optical axis. The vertical distance between the two wood grain lenses 4 is 0.5mm-6mm, and the reason for setting in this interval is that too small interval easily causes movement interference, and too large interval will cause the imaging depth between the two diamond glass lenses 3 to be increased, so that the imaging quality of the contour curve projection on the surface of the wood grain lenses 4 is deteriorated.

As shown in fig. 5, the contour projection line of the wood grain lens 4 is a plurality of regularly arranged spline curves, and the interval D between two adjacent spline curves is less than 2mm, so as to form a close and continuous laminated projection effect.

As shown in the attached figure 6, the surface of the wood grain lens is provided with a plurality of sawtooth-shaped stripes, the curvature radius R of the sawtooth-shaped stripes is more than or equal to 0.5mm and less than or equal to 3mm, which is convenient for forming peaks similar to fluctuation, thereby forming finer surge effect.

Both wood grain lenses 4 are driven by a motor to rotate around their central axes, as those skilled in the art will appreciate, the rotation structure is not complicated and is common knowledge. The two wood grain lenses 4 are arranged at different height positions and are respectively positioned at two sides of the main optical axis, and the light through holes 2 are partially overlapped, namely, light rays emitted from the light through holes 31 sequentially pass through the 2 wood grain lenses 4. The beneficial effect of this technical scheme lies in, can produce the combination stack effect through 2 wood grain lenses 4 for wood grain lenses 4's range upon range of surge effect is more diversified and randomization, thereby makes the water wave effect abundanter.

Preferably, the two wood grain lenses 4 are completely the same, which not only facilitates the control of the number of the types of raw materials, but also reduces the difficulty of process assembly.

The light rays emitted from the wood grain lens 4 are incident to the imaging lens group 5, and the imaging lens group 5 is a fixed-focus lens or a movable zoom lens. The advantage of this embodiment is that the discretized profile curve can still be discretized into a clear image.

Example two:

as shown in the attached drawing 2, the novel water wave projection lamp comprises a light source module 1, a color disc 7, a first condensing lens 2, a wood grain lens 4 and an imaging lens group 5 which are sequentially arranged along the emergent direction of light rays, wherein a light screen 3 is arranged between the first condensing lens 2 and the wood grain lens 4, and a light through hole 31 is formed in the middle of the light screen 3.

The structural difference between the first embodiment and the first embodiment is that a color chip tray 7 is additionally arranged between the light source module 1 and the first condensing lens 2, the color chip tray 7 contains a plurality of color chips, and each color chip comprises one or more colors.

As will be understood by those skilled in the art, the second embodiment has no other obvious difference from the first embodiment in principle and implementation effect except for the addition of the color effect of the color chip tray 7.

Example three:

as shown in the attached drawing 3, a novel water wave projection lamp comprises a light source module 1, a condensing lens 2, a wood grain lens 4, a disturbance lens 6 and an imaging lens group 5 which are sequentially arranged along the emergent direction of light, wherein a light screen 3 is arranged between the condensing lens 2 and the wood grain lens 4, and a light through hole 31 is arranged in the middle of the light screen 3.

As shown in fig. 7, light rays are sequentially emitted from the two wood grain lenses 4 and then enter the disturbing lens 6, at least one side surface of the disturbing lens 6 is provided with a plurality of arc-shaped plano-convex lenses, the adjacent arc-shaped plano-convex lenses are in continuous or discontinuous smooth transition, the curvature radius of the arc-shaped convex surface is continuously changed within 6-150 mm, and the height of the arc surface of the arc-shaped convex surface is continuously changed within 0.05-1.5 mm. The implementation mode has the advantages that the bending capability of the lens on light rays is increased due to the fact that the curvature radius is too small, aberration is increased to an unacceptable degree, the similarity degree of an object image is changed seriously, the image plane is distorted excessively and is distorted seriously, the plane tends to be formed due to the fact that the curvature radius is too large, the optical distortion of an imaging system is not changed, and the effect of image plane fluctuation distortion cannot be achieved.

The disturbing lens 6 can rotate around the central axis thereof after being driven by the motor, and the disturbing lens 6 and the two wood grain lenses 4 can rotate relatively around the axis parallel to the light path, and the rotation mode of the disturbing lens 6 and the two wood grain lenses is shown in figure 7. This embodiment has the advantage of discretizing the edges of the projected image of the profile curve of the wood grain lens 4, while allowing the image to have significant stacking and surge characteristics, achieving another water-ripple effect.

The distance between the disturbing lens 6 and the adjacent wood-grain lens 4 is 0.5-10 mm, preferably 2-3 mm, which embodiment has the advantage that too small a spacing easily leads to motion interference, while if too large a spacing increases the degree of distortion and aberrations of the disturbing lens 6 to the system power and ray deflection, which is unacceptably large.

The light emitted from the disturbance lens 6 is incident to the imaging lens group 5, and the imaging lens group 5 is a fixed-focus lens or a movable zoom lens. The advantage of this embodiment is that the discretized profile curve can still be discretized into a clear image.

Example four:

as shown in the attached drawing 4, the novel water wave projection lamp comprises a light source module 1, a color disc 7, a first condensing lens 2, a wood grain lens 4, a disturbance lens 6 and an imaging lens group 5 which are sequentially arranged along the emergent direction of light, wherein a light screen 3 is arranged between the first condensing lens 2 and the wood grain lens 4, and a light through hole 31 is formed in the middle of the light screen 3.

The structural difference between the third embodiment and the first embodiment is that a color chip tray 7 is additionally arranged between the light source module 1 and the first condensing lens 2, the color chip tray 7 contains a plurality of color chips, and each color chip comprises one or more colors. As can be understood by those skilled in the art, the fourth embodiment has no other obvious difference from the third embodiment in principle and implementation effect except for adding the color rendering effect of the color chip tray 7.
