Specific embodiment
The utility model proposes a kind of lamps and lanterns, structural schematic diagram is as shown in Figure 1.The lamps and lanterns include point light source 1101(hair
Luminous point is S0, therefore hereinafter also at point light source S0), at least two virtual image elements 1102 and 1103, collimating element 1104.It is wherein empty
Element 1102 and 1103 is all reflecting mirror, collects the part light 1301 and 1303 that point light source 1101 issues respectively, and by its point
It does not project in the effective aperture of collimating element.According to the basic optical principle of reflecting mirror it is found that this part light 1301 and 1303
Form the virtual image S1 of point light source S0 relative to the heteropleural of collimating element 1104 in virtual image elements (reflecting mirror 1102 and 1103) respectively
And S2, the light collimation that collimating element is used to be incident in its effective aperture.
According to optical principle it is recognized that while only one point light source S0, but after the effect of reflecting mirror 1102 and 1103,
It is equivalent to and three light sources: point light source S0, imaginary light source S1 and imaginary light source S2 has occurred, these three light sources are of similar shape.This
The light that three light sources issue is projeced into the effective aperture of collimating element simultaneously and collimated outgoing, forms three beams directional light.
It in the present embodiment, further include reflection mirror array 1105 positioned at collimating element optical path rear end, in reflection mirror array
Each sub- reflecting mirror can all say that parallel light emitting incident thereon forms small luminous point, this small luminous point is the equal of light
The picture (in imaged at infinity) in source.And due to the use of reflecting mirror 1102 and 1103, three point light source S0 of equivalent appearance,
S1 and S2, then on each sub- reflecting mirror will incident three beams directional light, and will after every sub- reflecting mirror reflection
Form the picture of these three point light sources, i.e. three small luminous points.There are multiple sub- reflecting mirrors, every sub- reflecting mirror institutes on reflection mirror array
The small luminous point formed is projeced into different directions；This just will form the small luminous point for being three times in sub- mirror count, to reach dress
Adorn effect.
In the present embodiment, further include color filter between 1104 optical path of point light source 1101 and collimating element.
In the present embodiment, the inherently reflection-type optical filter of reflecting mirror 1102, it can reflect the light of the spectrum of certain color, and its
Remaining light then transmits.Such as reflecting mirror 1102 can reflect feux rouges, other light transmissions.The light that so imaginary light source S1 is issued just is reflecting
Filtered in the reflection process of mirror 1102 and form feux rouges, thus imaginary light source S1 obtained after reflection mirror array 1105 it is small
Luminous point is all red.Importantly, which orientation generally filtered when optical filtering forms color of light excessively in optical path using optical filter
Some particular orientation it will form this within the scope of final hot spot and cross colour filter.Such as the light of filtering top, then it can be above
Projecting space forms red luminous point, i.e. red luminous point cannot be distributed in entire projecting space.But the effect of the present embodiment is then
It is different.As previously mentioned, there are multiple sub- reflecting mirrors on reflection mirror array, the small luminous point that every sub- reflecting mirror is formed by is projeced into
Different directions；That is imaginary light source seems that the sub- reflecting mirror reflected by multiple and different directions is distributed in entire projecting space
's.So in the present embodiment, for example, the light of imaginary light source S1 all becomes red after the filtering of reflecting mirror 1102, imaginary light source
It is red that S1 is formed by small luminous point, and is distributed across entire projecting space.This makes it possible to form at least two
The effect that the luminous point of color is interspersed, the luminous point of each color are distributed across entire projecting space.Actually in this reality
It applies in example, color filter can also paste on the mirror, and effect is identical.It is appreciated that realize face color point distribution
In the effect of entire projecting space, need to reach such condition: color filter covers at least partly optical path of a virtual image,
And do not cover at least partly optical path of another virtual image.In this way, different imaginary light sources just have different color performances；Due to each
Luminous point corresponding to imaginary light source can be distributed in entire projecting space, therefore point that the luminous point of different colours performance will be straggly
It is distributed in entire projecting space.
In the present embodiment, virtual image elements are reflecting mirrors, simultaneously by some light reflection of the point light source S0 non-optical axis issued
It projects in the effective aperture of collimating element.In fact, as long as virtual image elements are collected the part light that point light source issues and are thrown
It is mapped in the effective aperture of collimating element, and this part light forms point light source relative to the heteropleural of collimating element in virtual image elements
The virtual image, so that it may realize the purpose of this utility model.Such virtual image elements are other than the reflecting mirror of above-described embodiment, and there are also it
He selects, this can be further specified in embodiment below.
In the present embodiment, point light source S0 is illuminator.For example, point light source S0 can be LED chip, it is also possible to laser
Light source.Such laser light source includes laser source and flourescent sheet, and the laser of laser source transmitting focuses on flourescent sheet, it is made to be stimulated
Penetrate fluorescence.Due to the characteristic of the high collimation of laser, focus point can be very small, therefore emits the light face of fluorescence
Product very little, close is a geometric point.This light-emitting area is smaller, then the brightness of the luminous point projected is higher, decorative effect
Better.It is worth noting that, many places use the saying of point light source in this explanation, this does not imply that perfect light-emitting area levels off to
0 point light source, but the common name of the light source of light-emitting area.
In addition to real illuminator, actually point light source S0 is also possible to imaginary light source, i.e., the virtual image of one real light source, is one etc.
The light emitting source of effect.This has no effect on illuminating effect described above.Such as a light emitting source be located at the focus of a convex lens with
Interior, shining can be in the ipsilateral formation virtual image of primary luminous point after convex lens.The imaginary light source that this virtual image is constituted can be made
For the point light source S0 in the utility model embodiment.Such as in above-mentioned laser light source, so that it may it further include a convex lens,
The luminous point of flourescent sheet is located within the focus of the convex lens.An empty point light source can thus be formed.
In the embodiment shown in fig. 1, S0 forms two under the action of reflecting mirror (virtual image elements) as real luminous point
A luminous point S1 and S2 of shooting without hitting the target.However, the optical path of shoot without hitting the target luminous point S1 and S2 be it is identical (symmetrical above and below), it is quasi- light can be located at simultaneously
On the focal plane of straight element.And luminous 1302 optical path of S0 is obviously shorter than the luminous optical path of S1 (this is because the optical path of S1 passes through
Reach light collimating element again after crossing the reflection of reflecting mirror 1102, according to Triangle Principle, the sum of two side lengths are naturally larger than third
Side).Therefore, when S1 and S2 is located on the focal plane of collimating element, S0 is just necessarily located between focal plane and light collimating element,
The light beam 1302 that the S0 of defocus is issued in this way would not be collimated element and perfectly collimate, it is formed by by reflection mirror array
Small light spot will be bigger than normal.
In another embodiment of the utility model, for directly shining for real point light source S0, another virtual image member is used
Part forms another luminous point of shooting without hitting the target, is addressed this problem.The structural schematic diagram of the embodiment is as shown in Figure 2.
