the making and using of various example illustrative arrangements that incorporate aspects of the present application are discussed in detail below . it should be appreciated , however , that the illustrative examples disclosed provide many applicable inventive concepts that can be embodied in a wide variety of specific contexts . the specific examples and arrangements discussed are merely illustrative of specific ways to make and use the various arrangements , and the examples described do not limit the scope of the specification , nor do they limit the scope of the appended claims . for example , when the term “ coupled ” is used herein to describe the relationships between elements , the term as used in the specification and the appended claims is to be interpreted broadly , and while the term “ coupled ” includes “ connected ”, the term “ coupled ” is not to be limited to “ connected ” or “ directly connected ” but instead the term “ coupled ” may include connections made with intervening elements , and additional elements and various connections may be used between any elements that are described as “ coupled .” an intrinsically safe laser illumination system is one where additional control systems are not required to sequester or contain the collimated laser light from exiting the illumination system . the following paragraphs will illustrate a safe laser illumination system that operates safely without the need for additional safety systems . however , in alternative arrangements that are contemplated by the inventors , a sensor such as described above with respect to prior known arrangements can be used in conjunction with the intrinsically safe laser illumination system and the benefits of the use of the arrangements would still accrue in such an alternative arrangement . fig2 depicts a top view of an intrinsically safe laser illumination system 200 utilizing a folded light path . in fig2 , a laser illumination headlamp 202 contains a laser array 210 whose laser beams 230 are directed through apertures in a dichroic mirror 212 and through a focusing and collimating lens set 214 to focus on a reflective yellow phosphor element 218 . the light from the phosphor substrate travels back through the lens set 214 and is reflected off the dichroic minor 212 and out of the headlamp or illumination system 202 as depicted by light rays 250 . the lens set 214 may contain one or more lenses to achieve its purpose of collimating and focusing the laser beams on the reflective phosphor substrate . of special interest in this example of the present application is the function of the dichroic minor 212 which is mounted at an angle 232 to the laser diode array 212 . the approximate angle of the mirror in one example arrangement would be 45 degrees , however the mirror 212 can be arranged at other angles in such a manner that the light paths depicted are accomplished with the intent of reflecting laser beams 230 to a safe location in the case where the laser array 210 and dichroic mirror 212 become misaligned , as is further described below . the dichroic minor 212 reflects yellow and blue light on the front and back surfaces . the exception is that there is aperture area that is aligned to the laser diode array 210 which still reflects yellow light , but allows blue laser beams 230 to pass either direction through the minor . a better understanding of the laser diode array and dichroic mirror may be attained by examining the further details presented in fig3 a and 3b . fig3 a - 3b each depict in aspects of the present application a front view of a pair of arrangements for laser diode arrays and dichroic mirrors for an intrinsically safe laser illumination system . fig3 a illustrates a laser array 310 which contains , in a non - limiting example , eight laser diode sources 312 that are arranged in a square pattern . element 320 is a dichroic minor with a rectangular aperture 324 . dichroic minor 320 is designed to reflect blue and yellow light on front and back surfaces . an exception is the aperture area 324 which will allow blue light to pass in either direction . the size and position of the aperture 324 will coincide with the laser array 310 in such a manner that when the mirror 320 is aligned , in an example arrangement to illustrate the features , at about 45 degrees to the array , the mirror aperture 324 will allow the blue laser beams to pass through the minor 320 . laser array 310 is depicted with the laser sources 312 in a square pattern that corresponds to the minor aperture 324 in the mirror 320 that is rectangular when viewed directly from the front as illustrated , but not necessarily to scale . fig3 b depicts a second example arrangement of the present application with a laser array 316 where the laser diode sources 318 are arranged in a circular pattern . element 330 is another dichroic mirror with an oval aperture 334 . this minor 330 is designed to reflect blue and yellow light on front and back surfaces . an exception is the aperture area 334 which will allow blue light to pass in either direction . laser array 316 depicted with the laser sources 318 in a circular pattern corresponds to the mirror aperture 334 in the minor 330 being an oval shape when viewed directly from the front as illustrated , but is not necessarily drawn to scale . the inventor contemplates additional laser diode layout patterns and corresponding dichroic mirror arrangements that form further aspects of the present application , each of these arrangements will allow laser light to pass through one or more apertures in a minor while reflecting light in other areas of the mirror . example arrangement that are contemplated as providing additional aspects of the present application includes arrangements with multiple apertures in the mirror with corresponding laser layouts . in both of the non - limiting illustrative example arrangements shown in fig3 a and fig3 b , the minor apertures are symmetric to allow the laser beams to pass back to front through the minor and also front to back through the minor . in the event of a partial or total failure of the phosphor coating in a system incorporating the mirrors of fig3 a or 3b , the laser beams would be reflected off the substrate surface of the phosphor and then would be directed back through the symmetric aperture of the minor , preventing collimated laser light from exiting the headlight system . the following examples illustrate the intrinsically safe nature of this illumination system in view of different possible failure mechanisms . fig4 depicts in a top view the intrinsically safe illumination system of fig2 with a shifted laser diode array failure . depicted in 400 is an intrinsically safe illumination headlight or headlamp assembly 402 similar to 202 depicted in fig2 , retaining the numerical assignments , only now in the 400 series . assembly 402 includes the laser source 410 , laser beams 430 , dichroic minor 412 , phosphor element 418 and the light output 450 . in this illustration , the laser array 410 is shown shifted or rotated in position with respect to the dichroic minor 412 in such a manner that the laser beams 430 are now not aligned with the apertures in the dichroic minor 412 . in this example , the laser beams 430 are reflected away from the normal output direction 450 of the illumination system and do not exit the illumination system . this is an intrinsic safety feature of this arrangement and does not require any detectors , ecus nor power interrupt systems to contain the laser beams . power can remain on for the laser diodes 410 without endangering human or animal observers as no laser energy is emitted from assembly 402 at output 450 in this example failure . fig5 depicts in another example the intrinsically safe illumination system of fig2 with a missing yellow phosphor substrate failure . depicted in fig5 is an intrinsically safe illumination arrangement 502 such as was depicted in fig2 as 202 , retaining the numerical assignments , only in the 500 series . the assembly 502 includes the laser source 510 , laser beams 530 , dichroic minor 512 , lens set 514 , phosphor element 518 and the light output 550 . in this example , the yellow phosphor substrate 518 is not in its proper location . laser array 510 supplies laser beams 530 which are in alignment with the dichroic minor 512 . the laser beams pass thru the lens set 514 but do not energize the dislocated yellow phosphor substrate 518 . without striking the substrate 518 ( which is now out of the designed position ), the laser beams cross and are not reflected and are thus contained within the illumination system . in this example , the laser beams are contained away from the normal output direction 550 of the illumination system 500 and do not exit the illumination system . the system 500 is thus intrinsically safe . the safety features do not require any detectors , ecus nor power interrupt systems to contain the laser beams . power can remain on to the laser diode array 510 without risk that any laser energy is emitted from the assembly 502 . in yet another example , fig6 depicts in a top view an intrinsically safe laser illumination system 600 such as that of fig2 illustrating an example of a yellow phosphor coating failure . depicted in fig6 is an intrinsically safe illumination assembly 602 as depicted in fig2 retaining the numerical assignments , only now with numbers in the 600 series . the arrangement 602 of fig6 includes the laser source 610 , laser beams 630 , dichroic minor 612 , lens set 614 , phosphor element 618 and has the light output 650 . in this example illustration , the phosphor coating on element 618 has fully or partially delaminated exposing the reflective substrate of the phosphor element 618 in whole or part . in the example of fig6 , the laser array 610 produces laser beams 630 which pass thru an aperture in the dichroic minor 612 . the laser beams then pass through lens set 614 and are focused on the yellow phosphor element 618 . in this failure example , all or part of the laser beams will be reflected by the reflective substrate of the phosphor element 618 . with the symmetric nature of the laser array 610 and aperture on the dichroic minor 612 , the non - disbursed portion of the beams are simply reflected off the substrate and back to the original laser diodes as shown by the double ended beam arrow 630 . without the phosphor coating the beams are simply reflected and contained within the illumination system housing . this is an intrinsic safety feature of this arrangement and does not require any detectors , ecus nor power interrupt systems to contain the laser beams . fig7 depicts in a top view another example arrangement of an intrinsically safe laser illumination system 700 utilizing a linear light path . illustrated in fig7 is a top view of an intrinsically safe lighting assembly 702 which contains a laser light source 710 coupled to a condensing lens system 714 through a dichroic mirror 712 . the focusing lens directs light energy to a light dispersing element 718 . following the dispersing element 718 s a collimating lens set 716 which directs the light energy 750 out of the lighting assembly 702 thru a second dichroic minor 722 . in this example arrangement of the present application , a laser light source 710 , which has laser diodes arranged in a symmetric pattern , is aligned so that the laser beams 730 pass through an aperture in a dichroic mirror manufactured to pass the laser light . the laser light beams 730 are then focused by the condensing lens set 714 and directed to a yellow phosphor coated element 718 . when the laser light 730 hits the element 718 , the yellow phosphor fluoresces emitting a bright , dispersed light . that light consists of yellow and blue light and appears as white light . following element 718 is a collimating lens set 716 which gathers the emitted light and directs it out the front of the lamp system through a second dichroic minor 722 as depicted by beams 750 . for better explanation , the laser diode array and dichroic minor of fig7 are also detailed in fig8 a - 8b . fig8 a - 8b each depict in a front view of a pair of laser diode arrays and a pair of dichroic minors that can be used in the arrangements such as for the intrinsically safe laser illumination system of fig7 . fig8 a depicts a laser array 810 which contains , in this non - limiting illustrative example , eight laser diode sources 812 that are arranged in a symmetric pattern as a square or rectangle . more , or fewer , laser diode sources can be used in forming alternative arrangements . element 820 is a dichroic mirror with a square aperture 824 . dichroic minor 820 is designed to reflect blue and yellow light on front and back surfaces except in area 824 where blue light can pass in either direction through the dichroic minor . the size of the aperture 824 will correspond with the laser array 810 in such a manner that when the minor is aligned perpendicular to the laser light array , the mirror &# 39 ; s aperture 824 will allow the blue laser beams to pass through the mirror . element 822 is a second dichroic mirror with a square aperture 826 . dichroic minor 822 is designed to reflect blue light in the square area 826 and pass light in all other areas . the size of the reflective area 826 will correspond with the laser array 810 . fig8 b depicts another example of a laser diode light source 816 and minors 830 and 832 which can be used with the laser light illumination system in fig7 . laser light source 816 is illustrated with , in this example , six laser diodes sources 818 arranged in a symmetric circular pattern . dichroic minor 830 is provided with a circular shaped aperture 834 . the minor 830 reflects blue and yellow light on both surfaces except in the aperture area 834 where blue light is allowed to pass in either direction thru the minor . the aperture 834 is designed and sized so that when the minor 830 is positioned perpendicular to the laser light source 816 , the laser sources 818 are aligned with the aperture with their light passing through the aperture . dichroic minor 832 is provided with a circular shaped area 834 . the minor 832 reflects blue and yellow light in the circular area 836 and passes light in all other areas . the size of the reflective area 836 will correspond with the laser array 816 . in both example arrangements depicted in fig8 a and 8b , the area 824 , 826 are symmetric to allow the laser beams to pass through the mirror in both directions . the intrinsically safe features of the arrangements are discussed with respect to the following figures . in addition to these example arrangements , many other laser diode patterns can be used , and corresponding shapes can be formed on the dichroic mirrors as shown in the examples . alternative arrangements can be formed by using various patterns for the laser diodes and the minors as shown above . fig9 depicts in a top view an intrinsically safe illumination system 900 with an example shifted laser diode array failure . depicted in fig9 is an intrinsically safe illumination assembly 902 corresponding to the assembly 702 from fig7 . in fig9 , the numerical assignments from fig7 are retained , only now in the 900 series . assembly 902 includes the laser light source 910 , the dichroic mirror 912 , the condensing lens set 914 , the dispersing element 918 , collimating lens set 916 , second dichroic mirror 922 and the final light output 950 . in this example which is used to illustrate an intrinsically safe feature , the laser light source 910 is depicted as being shifted with respect to the dichroic minor 912 , so that the laser light 930 is no longer aligned with the aperture in the dichroic minor 912 . since the dichroic minor 912 reflects both blue and yellow light in the areas where the aperture is not located , the laser light is reflected back to the rear of the illumination system where it does not exit the lamp system . because the laser light does not exit the assembly 902 , this is an intrinsic safety feature of this arrangement and in sharp contrast to the prior known approaches , the intrinsically safe arrangements of the present application do not require any sensors , detectors , ecus nor power interrupt systems to contain the laser beams . fig1 depicts in another example 1000 the intrinsically safe illumination system of fig7 with a failed phosphor coating failure . depicted in fig1 is an intrinsically safe laser illumination system 1002 such as 702 from fig7 . in fig1 , the numerical assignments of fig7 are retained , only in the 1000 series . assembly 1002 includes the laser light source 1010 , the dichroic mirror 1012 , the condensing lens set 1014 , dispersing element 1018 , collimating lens set 1016 , the second dichroic minor 1022 and the final light output 1050 . in this example used to illustrate an intrinsically safe feature , the yellow phosphor element 1018 has become dislodged , having moved from its original location 1018 a to the example position 1018 . laser light 1030 retains its collimated composition since the phosphor element is no longer in place . the collimated laser light 1030 is considered dangerous and it should not exit the illumination system . in this failure example , the symmetric aperture nature of the reflective area on the second dichroic mirror 1022 , simply reflects the laser light back into the lens sets 1016 and then 1014 where it passes thru dichroic minor 1012 where it is contained within the illumination system 1002 . the laser light does not exit the assembly 1002 . this is an intrinsic safety feature of the arrangements of the present application , and unlike the prior known approaches , does not require any detectors , ecus nor power interrupt systems to contain the laser beams . thus the use of the novel arrangements of the present application provide an intrinsically safe laser illumination system . fig1 is a flow diagram illustrating an example method of creating an intrinsically safe illumination system . in fig1 , there are seven sequential steps illustrated in blocks 1101 , 1105 , 1107 , 1109 , 1111 a or 1111 b , 1113 , and 1115 . step 1101 begins the method 1100 by arranging a plurality of laser sources in a pattern providing a symmetric laser light source , typically sourced from blue laser diodes , that produces laser light beams . at step 1105 , a dichroic minor is provided with an aperture that corresponds to the pattern of the laser sources . at step 1107 , a phosphor element is provided positioned to receive laser beams from the laser sources through the aperture in the dichroic mirror . at step 1107 , light is outputted from the phosphor including fluorescent light and dispersed laser light to form combined light . at step 1111 a , in example arrangements such as illustrated in fig2 , the combined light is reflected from the dichroic minor , but in some arrangements that have the output in line with the phosphor , such as shown in fig7 , step 1111 b shows that the light will pass through a second dichroic mirror . in step 1113 , the illumination light is output from the system . the arrangements described herein can be incorporated into a laser source illumination headlight or headlamp . these headlights or headlamps can be used with a variety of vehicles including automotive and truck applications , marine applications , recreational applications such as snowmobiles , motocross , atvs and the like , airplane and aerospace applications . the bright light provided by the use of the laser illumination sources is not limited to vehicular applications and can also be applied to outdoor lighting , portable lighting , spotlights , flashlights , and a variety of other lighting environments . additional applications for lighting are also contemplated as benefitting from the use of the novel features of the arrangements . various modifications can also be made in the order of steps and in the number of steps to form additional novel arrangements that incorporate aspects of the present application , and these modifications will form additional alternative arrangements that are contemplated by the inventors as part of the present application and which fall within the scope of the appended claims . although the example illustrative
