Specific embodiment

To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with the application specific embodiment and Technical scheme is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the application one Section Example, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing Every other embodiment obtained under the premise of creative work out, shall fall in the protection scope of this application.

Below in conjunction with attached drawing, the technical scheme provided by various embodiments of the present application will be described in detail.

The embodiment of the present application discloses a kind of Projecting Lamp, as depicted in figs. 1 and 2, including light source module group 1, shell 2 and thoroughly Light shield 3.Shell 2 and translucent cover 3 surround accommodating chamber 4 jointly, and light source module group 1 is arranged in accommodating chamber 4, and light source module group 1 is sent out Light out can expose to the external world of lamps and lanterns through translucent cover 3.

As shown in Figure 3 and Figure 6, in the present embodiment, in order to enable Projecting Lamp to provide foot for the region except tens meters Enough illuminations need to be arranged the luminescence unit being made of many luminescence units 100 inside the light source module group 1 in the present embodiment Arrangement, the total quantity of luminescence unit indicate that n luminescence unit 100 is arranged in multiple annular regions 10, each with n Annular region 10 all has center 10a and datum mark 10b, and in the present embodiment, all datum mark 10b are relative to where it The position at the center of annular region 10 is all the same, for example, all datum mark 10b are in the three position of center 10a, or It can also be in six-o ' clock position, nine o'clock position or other any same positions.

After datum mark 10b is determined, position of each luminescence unit 100 in respective annular region 10 can be single by shining The central angle alpha that the center 10a of member 100, datum mark 10b and its annular region 10 at place is constituted determines.This position determines Mode is mainly used for determining that luminescence unit 100 has relative to center 10a in 360 degree around the 10a of center of angular range Body angle position, and for luminescence unit 100 relative to center 10a linear distance then without mark action.

Also, following item also is compliant between the position of the luminescence unit 100 in multiple annular regions 10 in the present embodiment Part:

Referring to fig. 4, it is assumed that there are a virtual ring 11, the virtual ring 11 have virtual center 11a and virtual reference point 11b, virtual reference point 11b are relative to the position of virtual center and each datum mark 10b above-mentioned relative to the annulus where it The position of the center 10a in domain 10 is identical.When all luminescence units 100 are arranged according to its position in annular region 10 When in virtual ring 11, the central angle difference of two neighboring luminescence unit 100 is 360 °/n, i.e., in virtual ring 11, all shines Unit 100 will take equidistant mode uniformly to be arranged.

If an annular is provide with except virtual ring 11 at this time to stretch lens and carry out mould to the whole hot spot of virtual ring 11 It is quasi-, it will be found that since the luminescence unit 100 in virtual ring 11 is all made of equidistant arrangement mode, each luminescence unit 100, which are formed by hot spot, to be outwardly formed radioactivity sector structure, all luminescence units 100 by basic point of virtual center 11a Hot spot be overlapped mutually, ultimately form the whole hot spot of virtual ring 11.In the whole hot spot of virtual ring 11, even if may be because of function The factors such as rate, light distribution lead to still have the filaments of sun between the hot spot of two neighboring luminescence unit 100, but circle corresponding to the filaments of sun Heart angle is also only limitted to the difference for the central angle that two neighboring luminescence unit 100 is spaced, i.e. 360 °/n.And with luminescence unit The increase of 100 quantity, the spacing of two neighboring luminescence unit 100 can be gradually reduced in virtual ring 11, to make the filaments of sun also can be by Fade and subtract, when the spacing of two neighboring luminescence unit 100 is close to luminescence unit is even less than from the object on central angle direction When managing size, it will appear luminescence unit 100 in virtual ring 11 and adjoin each other the case where even partially overlapping, each hair can be made in this way There is approaching and being overlapped for higher degree in the hot spot of light unit 100, dark in the whole hot spot so as to eliminate virtual ring 11 Item.

Above-mentioned is the analysis carried out to the whole hot spot of virtual ring 11, in actual lamps and lanterns product, each luminescence unit 100 be arranged in inside respective annular region 10 respectively, and it is not all be arranged in the same ring, therefore the present embodiment is every A annular region 10 be respectively equipped with annular stretch lens 12 all luminescence units 100 inside the annular region 10 are carried out it is whole Body light distribution (referring to Fig. 5).

Inside each annular region 10, each luminescence unit 100 be formed by hot spot will using center 10a as basic point to It is outer to form radioactive sector structure, the fan-shaped hot spot that luminescence unit 100 is formed at this time, Angle Position and size parameter in the center of circle On with it is essentially identical in virtual ring 11, will not change significant change, and only at 11 inside of virtual ring, its position is Using virtual center 11a as basic point, and its position is using the center 10a of the annular region 10 where it as base in actual products Point.There are following several grown forms for the relative position of the center 10a of each annular region 10:

The first, if the center 10a of annular regions 10 all at this time is overlapped, such as all annular regions 10 are in same Thimble is arranged (referring to Fig. 3), then the luminescence unit 100 inside multiple annular regions 10 be formed by whole hot spot substantially can be with It is consistent with the whole hot spot effect of virtual ring 11.

Second, if the center 10a of annular regions 10 all at this time is not overlapped, but be in planar array in two-dimensional surface Column arrangement (referring to Fig. 6), then in each annular region 10 each luminescence unit 100 be formed by will appear between hot spot it is certain inclined It moves, offset is equal to the spacing between each center 10a.For example, the vertical spacing of the center 10a of two neighboring annular region 10 is 10cm, then the hot spot of the two annular regions 10 will accordingly be staggered 10cm in the vertical direction.If two neighboring annulus Spacing is 10cm to the center 10a in domain 10 in the horizontal direction, then the hot spot of the two annular regions 10 will be accordingly in level side Be staggered 10cm upwards, and so on.The arrangement mode of annular region 10 can be according to various rules or irregular array arrangement, example Such as triangular array, hexagonal array, spirality array, circular array, wherein more simple with rectangular array arrangement Just.

Although the formed hot spot of each annular region 10 can have certain offset dislocation in this arrangement mode, due to throwing Light lamp be to tens meters of outer throw lights, therefore be formed by except tens meters hot spot be it is very huge, can often reach To the diameter of dozens or even hundreds of rice.And the offset center 10a of each annular region 10 mutual inside Projecting Lamp only exists Centimetres, caused by the hot spot degree that is staggered of each annular region 10 be very micro- for the whole hot spot of Projecting Lamp Small, therefore can ignore substantially, Projecting Lamp is formed by the whole hot spot effect of practical entirety hot spot Yu virtual ring 11 at this time It is still almost the same.

The third, if the center 10a of annular regions 10 all at this time lines up an axis, i.e., all annular regions 10 There is the offset along axis in stacking arrangement, such as offset is at this time between the center 10a of two neighboring annular region 10 10cm, the hot spot of two neighboring annular region 10 also can accordingly be staggered 10cm in the axial direction at this time.

This arrangement mode is similar with second of arrangement mode, although the formed hot spot of interior each annular region 10 can have one Fixed offset dislocation, but since Projecting Lamp is to tens meters of outer throw lights, being formed by hot spot except tens meters is It is very huge, it often can achieve the diameter of dozens or even hundreds of rice.And the center 10a of each annular region 10 in Projecting Lamp inside Mutual offset is only in centimetres, even each annulus of the two of the lie farthest away annular region 10 caused by it The hot spot in domain 10 degree that is staggered is still very small for the whole hot spot of Projecting Lamp, therefore can ignore substantially, At this time Projecting Lamp be formed by practical entirety hot spot and virtual ring 11 whole hot spot effect it is still almost the same.

Each annular region 10 can also arrange in addition to above-mentioned three kinds basic arrangement modes using by three kinds in the present embodiment The mixing arrangement mode that mode combines, although this arrangement mode is increasingly complex, for each luminescence unit 100, The offset of its hot spot remains very small for whole hot spot, therefore these Projecting Lamps are formed by practical entirety The whole hot spot effect of hot spot and virtual ring 11 is still almost the same.

And in the related art since the arrangement mode of the luminescence unit in all annular regions is identical, it is therefore assumed that Luminescence unit sum in the related technology is n, and the quantity of annular region is m, then the luminescence unit quantity in each annular region For n/m, still arranged using equidistant mode, then the central angle difference of two neighboring luminescence unit is 360 ° in the related technology M/n, due to m >=2,360 ° m/n >=2*360 °/n, i.e. the central angle difference of two neighboring luminescence unit in the related technology Can be at double in the central angle difference of luminescence unit two neighboring in the virtual ring of the present embodiment 11, therefore it is formed by filaments of sun model It encloses also wider.

Also, due in the related technology since the arrangement mode of the luminescence unit in all annular regions is identical, because Which kind of arrangement mode no matter this use, and is based on above-mentioned same principle, the luminescence unit in different annular regions at same position The state being overlapped mutually can be constantly in by being formed by hot spot, and the filaments of sun region between two neighboring luminescence unit is always not yet It can be irradiated to, therefore will form the apparent filaments of sun in the related technology.

To sum up, Projecting Lamp provided by the present embodiment can be weakened significantly under the premise of using identical quantity luminescence unit The degree and range of the radioactivity filaments of sun improve hot spot effect.

In the present embodiment, the diameter using each annular region 10 of the first arrangement mode is necessarily unequal, and uses The diameter of second and when the third arrangement mode each annular region 10 can be equal or unequal, and equal diameter is advantageous In assembly, and unequal diameter is more advantageous to saving space and forms be more good light distribution effect.

In addition, in the present embodiment, the quantity of the luminescence unit 100 in each annular region 10 can be identical referring to Fig. 7 It can also be different, be more conducive to the size for cooperating annular to stretch lens 12 in this way.For example, when multiple annular regions 10 are using same When thimble is arranged, the diameter positioned at the annular region 10 in bosom is minimum, and correspondingly the size of annular stretching lens 12 is also minimum, I.e. perimeter is most short, and 100 quantity of luminescence unit if necessary to arrangement is more at this time, may cause the inadequate problem of perimeter length. And due to being the position for determining each luminescence unit 100 with central angle in the present embodiment, it can be in larger-size outer layer More some luminescence units 100 of setting in annular region 10, and 100 quantity of luminescence unit of internal layer is reduced, to easily solve ruler The problem of very little anxiety.

Also, the as shown in fig. 7, arrangement mode of the luminescence unit 100 inside each annular region 10 in the present embodiment It is but changeable without using equidistant mode, as long as guaranteeing that the luminescence unit 100 in virtual ring 11 is equidistant arrangement It can guarantee final whole hot spot effect, so that more flexibilities are added in the structure design for Projecting Lamp.

In the present embodiment, the projection distance according to needed for Projecting Lamp, intensity of illumination, the size of luminescence unit 100 and The quantity of annular region 10 and luminescence unit 100 can be adjusted flexibly in the parameters such as power, for example, using 60 in the present embodiment The luminescence unit 100 of 3030 models can form substantially homogeneous whole hot spot.And under normal conditions, luminescence unit in Projecting Lamp 10 total quantity is not less than 10, i.e. n >=10.Annular disclosed in the embodiment of the present application stretches lens 12 can be all-trans for annular Penetrate lens.As shown in Fig. 8 to Figure 10, annular total reflection lens include annular light distribution portion 120.Annular light distribution portion 120 is total reflection Lens arrangement has light-emitting surface 1200, the first incidence surface 1201, inside incidence surface 1202, outside incidence surface in a ring 1203, inner reflection face 1204 and outside reflecting surface 1205.Wherein, be with the direction close to ring heart it is interior, with separate ring heart Direction be it is outer, inside incidence surface 1202 and outside incidence surface 1203 are located at the inside and outside two sides of the first incidence surface 1201, three Annular is collectively formed enters optical cavity 1206.Light-emitting surface 1200 is located at the front of the first incidence surface 1201, inner reflection face 1204 Positioned at the inside of inside incidence surface 1202, outside reflecting surface 1205 is located at the outside of outside incidence surface 1203, inner reflection face 1204 with outside reflecting surface 1205 from enter optical cavity 1206 to light-emitting surface 1200 extend.

As shown in figure 21, the light that luminescence unit 100 is issued is entered inside annular light distribution portion 120 by entering optical cavity 1206. Wherein, the light entered by the first incidence surface 1201 directly can be emitted (optical path a) by light-emitting surface 1200；By inside incidence surface 1202 light entered can be refracted to inner reflection face 1204 by inside incidence surface 1202, then be reflexed to by inner reflection face 1204 Light-emitting surface 1200 is finally emitted (optical path b) by light-emitting surface 1200；The light entered by outside incidence surface 1203 can enter light by outside Face 1203 refracts to outside reflecting surface 1205, then reflexes to light-emitting surface 1200 by outside reflecting surface 1205, finally by light-emitting surface 1200 outgoing (optical path c).

Due to the presence in inner reflection face 1204 and outside reflecting surface 1205, annular light distribution portion 120 can surround a tool There is certain thickness housing region 124.For lamp interior space is made full use of, reducing lamps and lanterns size, save the cost etc. considers, Some devices, such as driving mould group, structural connection etc. would generally be set inside housing region 124.These devices are function Can device, therefore appearance is not much fastidious, and aesthetics is not high.

In order to avoid user or other staff observe directly these devices and influence the overall aesthetics of lamps and lanterns, this implementation Example covers housing region 124 using occlusion part 122, and occlusion part 122 has with light-emitting surface 1200 towards consistent outer surface 1220 And the inner surface 1222 away from outer surface 1220, outer surface 1220 are connect with light-emitting surface 1200.In some embodiments, light out Face 1200 can be plane, and in further embodiments, light-emitting surface 1200 is also likely to be curved surface (such as convex surface).Outer surface Apparent boundary or outer surface 1220 and light-emitting surface 1200 or integrated can be formed between 1220 and light-emitting surface 1200 Setting can not obviously tell the boundary of the two from appearance.Such as outer surface 1220 and light-emitting surface 1200 form integral planar Structure or outer surface 1220 and light-emitting surface 1200 form smooth whole curved-surface structure.

In the present embodiment, occlusion part 122 is also an integral structure with 120 entirety of annular light distribution portion, therefore occlusion part 122 It is also substantially transparent material, luminous flux with higher, therefore occlusion part 122 cannot block appearance by traditional shading principle It receives region 124, but needs to find other schemes.

As shown in figure 9, the present embodiment is placed with the screening being made of several optical block structures 1224 on occlusion part 122 Array is kept off, optical block structure 1224 can reflect perhaps reflection light or have the energy of refraction and reflection light simultaneously Power.

The array that blocks for the composition of optical block structure 1224 that the present embodiment is arranged on occlusion part 122 on the one hand being capable of benefit With own form to housing region 124 carry out it is a degree of block, on the other hand can also using refraction or reflection make light Line deflects, and light can make the image of script be distorted, lack after being deflected by optical block structure 1224, to avoid Observer is clearly observed housing region internal situation by outside.Therefore, the present embodiment passes through optical block structure 1224 Above-mentioned two aspects effect can integrally improve the aesthetics of lamps and lanterns.

In the present embodiment, since outer surface 1220 and light-emitting surface 1200 are the faces for facing observer directly, for the ease of Cleaning and whole cleaning consider that optical block structure 1224 is preferably provided on inner surface 1222.Optical block structure 1224 can protrude relative to inner surface 1222 can also be relative to interior (i.e. to protruding inside housing region 124, referring to Figure 10) The recess of surface 1222 (i.e. exterior surface 1220 is recessed, referring to Figure 11).

There is no limit as long as can be realized the refraction to light for concrete shape of the present embodiment to optical block structure 1224 Or reflection.Such as shown in Figure 12 and Figure 13, optical block structure 1224 can be arranged in it is micro- on inner surface 1222 Pearl, microballon are substantially the arc-shaped minute protrusions being arranged on inner surface 1222, and multiple microballons, which can arrange, forms similar insect Multiple the structure of the eye, also referred to as fly's-eye lens.The light distribution principle of single microballon structure is similar to convex lens, by arc surface to light into Row refraction.In addition to this it can also carry out shining line on inner surface 1222 and form multiple reflection points light is reflected.

Other than above two scheme, as shown in Fig. 8 to 11 and Figure 14 to 20, optical block structure 1224 can be with For following shape: in the section perpendicular to inner surface 1222, figure that optical block structure 1224 and inner surface 1222 are constituted Shape is the isosceles triangle for taking inner surface 1222 bottom of as.

Specifically, as shown in figure 14, the shape that optical block structure 1224 and inner surface 1222 are constituted can be in extension The direction triangular prism parallel with inner surface 1222.Or as shown in Fig. 8 to 11 and Figure 15, Figure 19,20, optical block structure 1224 shapes constituted with inner surface 1222 can be short transverse perpendicular to the orthopyramid of inner surface 1222.

Either triangular prism or orthopyramid are to carry out by relative to the inclined side of inner surface 1222 to light Reflection or refraction, therefore can control the control light mode of side by way of the tilt angle changing side.Specifically, may be used To define a micro- corner angle x in the inside of optical block structure 1224, the inclination journey of side is indicated by the size of micro- corner angle x Degree.

In the present embodiment, there is some difference for the definition of micro- corner angle x of various optical block structures 1224, but principle is It is identical.As shown in figure 16, in triangular prism, two optical block structures adjacent with inner surface 1222 in triangular prism are defined The angle that 1224a is constituted is micro- corner angle x.When the bottom surface of orthopyramid is odd number regular polygon, one in orthopyramid is defined The angle that the middle line 1224c for crossing vertex of incline 1224b and opposite optical block structure 1224a is constituted is micro- corner angle x, Figure 17 shows micro- corner angle x of positive triangular pyramid, other bottom surfaces are that the orthopyramid of odd number regular polygon is similar with its.And work as orthopyramid Bottom surface be even number regular polygon when, define orthopyramid in two opposite optical block structure 1224a cross vertex in The angle that line 1224c is constituted is micro- corner angle x, and Figure 18 shows micro- corner angle x of positive rectangular pyramid, and other bottom surfaces are that even number is just more The orthopyramid of side shape is similar with its.

When x=90 ° of micro- corner angle, for most of materials, other than only a few high angle scattered light that may be present, Most of light can be incited somebody to action by the continuous reflection backtracking of two optical block structure 1224a, therefore substantially It is obstructed substantially by the light of occlusion part 122, to make observer that can not observe the situation in housing region 124.

When in certain OK range as micro- corner angle x and non-90 degree, but near 90 °, a part of angle can be made to be suitble to Light by occlusion part 122, and other unsuitable light is made to be reflected or be refracted to other places, to show to appearance It receives the optical effect of 124 partial occlusion fractional transmission of region, builds a kind of dim sense to observer.Due to the refraction of unlike material Rate is different, therefore there is also differents for the range of micro- corner angle x.For example, when the material of optical block structure 1224 is PC (poly- carbon Acid esters) when, the value range of micro- corner angle x is 60 °≤x < 90 ° or 90 ° < x≤103 °, i.e., from 60 ° to 103 ° within the scope of remove 90 ° Other values in addition.And when the material of optical block structure 1224 is PMMA (polymethyl methacrylate), micro- corner angle x Value range be 60 °≤x < 90 ° or 90 ° < x≤97 be from 60 ° to 97 ° within the scope of other values in addition to 90 deg..

When the value range further expansion of micro- corner angle x, such as the material of optical block structure 1224 is PC, and micro- The value range of corner angle x is x<60 ° or x>103 ° or the material of optical block structure 1224 is PMMA, and micro- corner angle x takes When value range is x<60 ° or x>97 °, most of light can pass through occlusion part 122 by way of refraction, and optics hides at this time The own form cooperation that relies primarily on of gear structure 1224 improves decorative effect to the distortion of light, deviation and other effects.

In the present embodiment, several optical block structures 1224 blocked in array can be using the arrangement mode of alignment (referring to Fig. 9), can also be using the arrangement mode for mutually staggering certain body position (referring to Figure 19).And it can be with blocking in array It, can also be multiple using the composition of optical block structure 1224 of two or more simultaneously using single optical block structure 1224 Combined array column, such as block array shown in Figure 20 and formed with positive triangular pyramid and positive hexagonal pyramid, more gorgeous decoration can be obtained Effect.

In conclusion annular total reflection lens, light source module group and Projecting Lamp provided by the embodiment of the present application can mention High aesthetics.

Emphasis describes the difference between each embodiment, difference between each embodiment in the application foregoing embodiments As long as optimization feature non-contradiction, can combine to form more preferably embodiment, it is contemplated that style of writing is succinct, then no longer superfluous at this It states.

The above description is only an example of the present application, is not intended to limit this application.For those skilled in the art For, various changes and changes are possible in this application.All any modifications made within the spirit and principles of the present application are equal Replacement, improvement etc., should be included within the scope of the claims of this application.
