Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
It please refers to shown in Fig. 1 and 2, it mainly to include lamp body, lamp that the present embodiment provides a kind of orientable lamps and lanterns for adjusting hot spot
Body includes light source 1, optical element and fixed cylinder 2, and the rear of light source 1 is provided with radiator 5, and fixed cylinder 2 is fixed on radiator 5
It is arranged wherein on shell and by light source 1, is covered with outline border 6 outside fixed cylinder 2, outline border 6 is connect with the shell of radiator 5, on outline border 6
The nozzle of corresponding fixed cylinder 2 is provided with the panel 7 that can be opened and closed, and the setting of 2 face light source 1 of fixed cylinder, optical element includes lens
3, the first polarizer 41 and the second polarizer 42, the first polarizer 41, the second polarizer 42 are all made of microlens array structure, Gu
One end on safety barrel 2 far from light source 1 is provided with limiting section 21, and lens 3 are placed in fixed cylinder 2 and are limited by limiting section 21, limited
Two pairs of different buckles of height 22 are additionally provided on the outside of portion 21, the first polarizer 41, the second polarizer 42 are able to rotatably
It is embedded in these two pair buckle 22, lens 3, the first polarizer 41 and the second polarizer 42 are successively arranged in the front of light source 1.
Microlens array herein is made of the upper half of the convex lens of several deviation light in the same direction.Collimated light beam warp
Its focal point can be converged at by crossing convex lens, and collimated light beam passes through the top half of convex lens, light beam can deviation down, in fact root
According to aplanatism principle, all light beams pass through the top half of convex lens, all can deviation down.Small lenticule square is made into this
Battle array, can play the role of deviation light.
It is provided with graduation mark 43 on first polarizer 41, the second polarizer 42, for identifying the relatively inclined of two polarizers 4
Gyration.The adjustable extent of opposite deflection angle is 0 °~180 °.At 0 °, two 4 deviation effects of polarizer are superimposed, out light projection
Angle is maximum；At 180 °, two 4 deviation effects of polarizer are offset, and light projection angle is minimum out.
The edge setting of two polarizers 4 is for convenience of the zigzag 44 driven.The regulative mode of two polarizers 4 is manual
Or it is electronic.Electronic mode can be is arranged drive shaft or driving gear etc. in lamp body, so that polarizer rotates specific angle
In addition degree assists intelligent algorithm control, may be implemented accurately to automatically control.And manual mode, as shown in figure 3, need to only open face
Plate 7 can be operated directly.
For the hot spot adjusting method of the lamps and lanterns of above-mentioned orientable adjusting hot spot, comprising the following steps:
1) it calibrates, the graduation mark 43 adjusted on two polarizers 4 is aligned, i.e., the opposite deflection angle of two polarizers 4 is
0°；
2) it adjusts single polarizer 4 to rotate, collapses hot spot to 1 face position of light source with involute path；
3) it keeps the opposite deflection angle of two polarizers 4 to fix, while adjusting two polarizers 4 and rotating, so that hot spot
It is mobile to make circular trace centered on 1 face position of light source；
4) repeat 2), 3) step, so that hot spot is moved to target position.
It should be noted that its principle is that the light that light source 1 projects is reflected twice by realizing after two polarizers 4, lead to
The opposite deflection angle for overregulating two polarizers 4, changes light projection angle out, is illustrated in figure 4 the polarisation effect of two polarizers
Fruit figure.
The adjustable extent of opposite deflection angle is 0 °~180 °, and when opposite deflection angle is 0 °, light projection angle is maximum out,
I.e. farthest away from 1 face position of light source；When opposite deflection angle is 180 °, light projection angle is minimum out, i.e., near 1 face of close to sources
Position.
It is emphasized that single polarizer 4 go out light projection angle be it is fixed, be used alone and rotate single polarizer
When 4, optical track mark is a fixed circle out.And two polarizers 4 can be the polarizer at same light projection angle out, be also possible to
Difference goes out the polarizer at light projection angles, and various combination can obtain different light direction adjustment effects, can according to specific needs,
The polarizer for going out light projection angle that replacement needs.
Assuming that being the polarizer at two same light projection angles out, as shown in figure 5, when the opposite deflection angle of the two is 0 °
When, light is by the superposition of two 4 deviation effects of polarizer, and 1 face position of hot spot facing light sources is farthest at this time, at this time light projection out
Angle is maximum；When the opposite deflection angle of the two is 180 °, light is just offset by two 4 deviation effects of polarizer, at this time
Hot spot is in 1 face position of light source, and light projection angle is minimum out at this time.When two polarizers 4 opposite deflection angle from 0 °~
When 180 ° of gradual changes, involute that track is gradually collapsed similar to one；When two polarizers 4 opposite deflection angle from 180 °~
When 0 ° of gradual change, involute that track is gradually dissipated similar to one.
The orientable lamps and lanterns for adjusting hot spot, have the advantages that
1) structure is simple, and two polarizers are added on existing fitting structure, is not necessarily to additional adjusting angle mechanism；
2) principle is reasonable, ingenious, and feasibility is high；
3) easy to adjust, effect is obvious；
4) research and develop it is at low cost, can integrated level it is high, be suitable on various lamps and lanterns.
To sum up, the lamps and lanterns of above-mentioned orientable adjusting hot spot, structure is simple, and principle is ingenious, and two are added in lamps and lanterns partially
Tabula rasa changes light refraction angles by two polarizers of rotation and changes light projection angle out, can in certain illumination zone,
The free deflection for realizing projected spot, is oriented illumination, eliminates additional adjusting angle mechanism, and lamps and lanterns exploitation is greatly saved
Cost and period, while it being not take up too many lamps and lanterns volume, the original structure of lamps and lanterns is had substantially no effect on, provides collection for various lamps and lanterns
At thinking.
