- Embodiments of invention are directed to a lighting device for use in accent lighting applications.
- the lighting device includes a coherent light source, such as a laser, and a diffractive optical element.
- the diffractive optical element may be, for example, a holographic optical element.
- the lighting device may be adapted to retrofit into a pre-existing light fixture.
- the lighting device may project a static or movable star field and/or static or movable clouds.
- DOE diffractive optical element
- Traditional optical elements use their shape to bend light.
- diffractive optics break apart incoming waves of light into a large number of waves which then recombine to form completely new waves.
- DOEs can function as grating, lenses, aspheric or any other type of optical element. They offer unique optical properties that are not possible with conventional optical elements.
- DOEs can be fabricated in a wide range of materials including, but not limited to, aluminum, silicon, silica or plastic.
- Holography is a technique that allows the light scattered from an object to be recorded and later reconstructed so that it appears as if the object is in the same position relative to the recording medium as it was when recorded.
- the image changes as the position and orientation of the viewing system changes in exactly the same way is if the object were still present, thus making the recorded image, termed a hologram, appear three-dimensional.
- FIG. 1 illustrates an optical path set-up to produce a hologram.
- a hologram can be produced from laser-light beams being scattered off of an object and interfered with by a reference beam.
- a two-dimensional recording medium such as a photosensitive plate or holographic film, records three-dimensional volumetric phase information of an object which is termed a fringe or iterative Fourier transfer algorithm (IFTA) pattern.
- IFTA iterative Fourier transfer algorithm
- This procedure is similar to photography where white light scattered from photographed objects is recorded on silver halide film.
- Light has a phase (volume) and amplitude (intensity) but only intensity is recorded in conventional photography.
- a hologram stores both amplitude and phase due to the interference of the reference beam. This reference beam possesses the same characteristics as scattered light because of the action of the laser.
- the phase information is the most important factor in holography because it provides the depth cues to the eyes and allows for an image to appear in three dimensions.
- a computer-generated holographic image is computed by numerically simulating the physical phenomena of light diffraction and interference. It is possible for computer software to calculate the phase of light reflected or transmitted from or through an object. Computing the phase of light of different objects, such as points, lines and wire frames, produces an interferential simulation that may in turn by transferred to a photographically sensitive media.
- a holographic optical element is a type of DOE.
- a holographic optical element is a hologram of a point source and acts as a lens or a minor having optical power, i.e., the ability to focus light.
- the hologram consists of a diffraction pattern rendered as a surface relief which may be, for example, a thin film (created using photoresist and/or dichromated gelatin) containing an index modulation throughout the thickness of the film.
- Index modulation refers to a periodic feature set that has a linear distribution of patterns to produce novel optical effects created during the process of making the HOE.
- Either process can be used to create a mathematical distribution to create a linear derivative producing a periodic feature set implemented into a phase mask.
- a non-linear implementation of IFTA produces a logarithmic or otherwise hyperbolic IFPTA wave function that may be used to produce non-linear phase derivatives onto a diffractive surface.
- holograms can be classified into two categories: (i) “reflection holograms” in which incidence and diffracted light are on the same side of the HOE; and (ii) “transmission holograms” in which incident and diffracted light are on opposite sides.
- FIG. 2 illustrates an exploded view of a lighting device according to an embodiment of the invention.
- Lighting device 200 may include a laser 202 (not shown) within a housing (not shown) situated within a heatsink 204 .
- Heatsink 204 may absorb and dissipate heat emanating from laser 202 when power is supplied thereto.
- Heatsink 204 may be any suitable configuration; however, in any embodiment, heatsink 204 should define a lumen 206 therein. In the embodiment shown, heatsink 204 is approximately rectangular in configuration.
- lumen 206 allows light emanating from laser 202 to project therethrough. That is, heatsink 204 generally surrounds a housing (not shown) which houses laser 202 .
- Heatsink 204 may be made of a metal material and may have a plurality of fins to expand the surface area for increased heat dissipation.
- laser 202 may be positioned to direct its light emanating therefrom through a holographic optical element 208 . That is, HOE 208 may be positioned within a light pathway of laser 202 . In an alternative embodiment, HOE 208 may be embossed and integrated into the collimation optics of laser 202 .
- the laser of lighting device 200 is a diode pumped solid state (DPSS) laser.
- DPSS laser is a device that converts some form of energy (e.g., electrical, optical, chemical) into a narrow beam of light which is monochromatic, directional and coherent.
- Monochromatic means pertaining to light of one color or to radiation of a single wavelength or narrow range of wavelengths.
- Directional means that the beam of light is very well columnated and travels over long distances with very little spread in diameter.
- “Coherent” means of or pertaining to waves that maintain a fixed phase relationship. The effect of one wave enhances the strength of every other wave so that the overall effect of coherent light is much greater than if the waves were not in phase.
- the DPSS laser may be an FLPPS Class 2 single beam laser with a total laser power of about two hundred (200) milliWatts.
- the laser of lighting device 200 is a direct diode laser light source whereas the laser light is produced from a solid state diode directly rather that a multiple optical crystal laser as in a DPSS type.
- HOE 208 may be positioned within a stem 210 a of a snap ring 210 with a snap ring retainer 212 positioned adjacent a bottom surface of HOE 208 and also within stem 210 a.
- snap ring 210 , HOE 208 and snap ring retainer 212 are all cylindrical or circular in configuration.
- at least snap ring 210 and snap ring retainer 212 include an opening through their centers. This feature allows the light emanating from laser 202 to pass through HOE 208 without interference from these supporting components, i.e., snap ring 210 and snap ring holder 212 .
- stem 210 a of snap ring 210 may be internally threaded while snap ring holder 212 may be externally threaded.
- snap ring holder 212 may threadedly engage with stem 210 a of snap ring 210 with HOE 208 situated therein.
- the resultant combination may be fitted within a housing (not shown) within the lumen 206 of heatsink 204 .
- a switched-mode power supply (SMPS) 214 may be in electrical communication with laser 202 via a wire or wires or any other means known by one of ordinary skill in the art.

Abstract
Description

- Lighting device for accent lighting applications.
- Lighting design is both a science and an art. Comprehensive lighting design requires consideration of the amount of functional light provided, the energy consumed, as well as the aesthetic impact supplied by the lighting system. Lighting in such venues as casinos, theatres, nightclubs and concert stages are primarily concerned with enhancing the appearance and emotional impact of the architecture or concert through lighting systems. Therefore, it is important that the sciences of light production and luminaire photometrics are balanced with the artistic application of light as a medium in our built environment. Often, accent lighting for the type of venues described above can be extremely sophisticated and costly.
- Smaller venues, such as restaurants, small businesses or even a home, also employ accent lighting. Such accent lighting is typically limited to “dimmer” lighting capabilities and/or monochromatic lighting. To utilize more sophisticated lighting systems in these types of venues can require special equipment, extensive electrical rewiring, and can often be cost-prohibitive.

The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention.
- Embodiments of invention are directed to a lighting device for use in accent lighting applications. In one embodiment, the lighting device includes a coherent light source, such as a laser, and a diffractive optical element. The diffractive optical element may be, for example, a holographic optical element. The lighting device may be adapted to retrofit into a pre-existing light fixture. In one application, the lighting device may project a static or movable star field and/or static or movable clouds.
- A diffractive optical element (DOE) is a class of optics that operates on the principle of diffraction. Traditional optical elements use their shape to bend light. By contrast, diffractive optics break apart incoming waves of light into a large number of waves which then recombine to form completely new waves. DOEs can function as grating, lenses, aspheric or any other type of optical element. They offer unique optical properties that are not possible with conventional optical elements. In addition, DOEs can be fabricated in a wide range of materials including, but not limited to, aluminum, silicon, silica or plastic.
- Holography is a technique that allows the light scattered from an object to be recorded and later reconstructed so that it appears as if the object is in the same position relative to the recording medium as it was when recorded. The image changes as the position and orientation of the viewing system changes in exactly the same way is if the object were still present, thus making the recorded image, termed a hologram, appear three-dimensional.
FIG. 1 illustrates an optical path set-up to produce a hologram. - A hologram can be produced from laser-light beams being scattered off of an object and interfered with by a reference beam. A two-dimensional recording medium, such as a photosensitive plate or holographic film, records three-dimensional volumetric phase information of an object which is termed a fringe or iterative Fourier transfer algorithm (IFTA) pattern. This procedure is similar to photography where white light scattered from photographed objects is recorded on silver halide film. Light has a phase (volume) and amplitude (intensity) but only intensity is recorded in conventional photography. A hologram, however, stores both amplitude and phase due to the interference of the reference beam. This reference beam possesses the same characteristics as scattered light because of the action of the laser. The phase information is the most important factor in holography because it provides the depth cues to the eyes and allows for an image to appear in three dimensions.
- In the computer science field, a computer-generated holographic image is computed by numerically simulating the physical phenomena of light diffraction and interference. It is possible for computer software to calculate the phase of light reflected or transmitted from or through an object. Computing the phase of light of different objects, such as points, lines and wire frames, produces an interferential simulation that may in turn by transferred to a photographically sensitive media.
- A holographic optical element (HOE) is a type of DOE. A holographic optical element is a hologram of a point source and acts as a lens or a minor having optical power, i.e., the ability to focus light. The hologram consists of a diffraction pattern rendered as a surface relief which may be, for example, a thin film (created using photoresist and/or dichromated gelatin) containing an index modulation throughout the thickness of the film. “Index modulation” refers to a periodic feature set that has a linear distribution of patterns to produce novel optical effects created during the process of making the HOE. Either process (dichromated gelatin or photoresist) can be used to create a mathematical distribution to create a linear derivative producing a periodic feature set implemented into a phase mask. In one embodiment of the invention, a non-linear implementation of IFTA produces a logarithmic or otherwise hyperbolic IFPTA wave function that may be used to produce non-linear phase derivatives onto a diffractive surface. According to embodiments of the invention, holograms can be classified into two categories: (i) “reflection holograms” in which incidence and diffracted light are on the same side of the HOE; and (ii) “transmission holograms” in which incident and diffracted light are on opposite sides.

FIG. 2 illustrates an exploded view of a lighting device according to an embodiment of the invention.Lighting device 200 may include a laser 202 (not shown) within a housing (not shown) situated within aheatsink 204.Heatsink 204 may absorb and dissipate heat emanating from laser 202 when power is supplied thereto.Heatsink 204 may be any suitable configuration; however, in any embodiment,heatsink 204 should define alumen 206 therein. In the embodiment shown,heatsink 204 is approximately rectangular in configuration. In addition to securing laser 202 (within the housing),lumen 206 allows light emanating from laser 202 to project therethrough. That is,heatsink 204 generally surrounds a housing (not shown) which houses laser 202.Heatsink 204 may be made of a metal material and may have a plurality of fins to expand the surface area for increased heat dissipation. In one embodiment, laser 202 may be positioned to direct its light emanating therefrom through a holographicoptical element 208. That is,HOE 208 may be positioned within a light pathway of laser 202. In an alternative embodiment,HOE 208 may be embossed and integrated into the collimation optics of laser 202. - In some embodiments, the laser of
lighting device 200 is a diode pumped solid state (DPSS) laser. A DPSS laser is a device that converts some form of energy (e.g., electrical, optical, chemical) into a narrow beam of light which is monochromatic, directional and coherent. “Monochromatic” means pertaining to light of one color or to radiation of a single wavelength or narrow range of wavelengths. “Directional” means that the beam of light is very well columnated and travels over long distances with very little spread in diameter. “Coherent” means of or pertaining to waves that maintain a fixed phase relationship. The effect of one wave enhances the strength of every other wave so that the overall effect of coherent light is much greater than if the waves were not in phase. In one embodiment, the DPSS laser may be an FLPPS Class 2 single beam laser with a total laser power of about two hundred (200) milliWatts. In other embodiments, the laser oflighting device 200 is a direct diode laser light source whereas the laser light is produced from a solid state diode directly rather that a multiple optical crystal laser as in a DPSS type. - To fix
HOE 208 within the light path of laser 202 (when power is supplied thereto),HOE 208 may be positioned within astem 210 a of asnap ring 210 with asnap ring retainer 212 positioned adjacent a bottom surface ofHOE 208 and also withinstem 210 a. In one embodiment,snap ring 210,HOE 208 andsnap ring retainer 212 are all cylindrical or circular in configuration. Moreover, atleast snap ring 210 andsnap ring retainer 212 include an opening through their centers. This feature allows the light emanating from laser 202 to pass throughHOE 208 without interference from these supporting components, i.e.,snap ring 210 andsnap ring holder 212. Also, in one embodiment, stem 210 a ofsnap ring 210 may be internally threaded whilesnap ring holder 212 may be externally threaded. As a result,snap ring holder 212 may threadedly engage withstem 210 a ofsnap ring 210 withHOE 208 situated therein. The resultant combination may be fitted within a housing (not shown) within thelumen 206 ofheatsink 204. - In one embodiment, a switched-mode power supply (SMPS) 214 (individual components not shown) may be in electrical communication with laser 202 via a wire or wires or any other means known by one of ordinary skill in the art. An SMPS is an electronic power supply unit (PSU) that incorporates a switching regulator in order to provide the required output voltage. In one embodiment, the
SMPS 214 may be affixed to an outer surface ofheatsink 206; however, other suitable locations forSMPS 214 are within the scope of the invention. In an alternative embodiment, a linear power supply may be used in place ofSMPS 214 to provide the necessary drive voltage and current. In the embodiment in whichSMPS 214 is affixed to the outside service ofheatsink 204,SMPS 214 may be affixed by screws andwashers 216 or equivalent affixing mechanism known by one of ordinary skill in the art. A distal end of awire 218 may be electrically connected toSMPS 214 while a proximal end of wire 218 (not shown) may be in electrical communication with another circuit board (not shown) and eventually to an outside power source (not shown). In one embodiment, ablanket 220 may be positioned on an opposite side ofheatsink 204 relative to SMPS 214 (as shown). - A switched-mode power supply (SMPS) is an electronic power supply unit (PSU) that incorporates a switching regulator. The SMPS rapidly switches a power transistor between saturation (full on) and cutoff (completely off) with a variable duty cycle whose average is the desired output voltage. The resulting rectangular waveform is low-pass filtered with an inductor and capacitor. The main advantage of this method is greater efficiency because the switching transistor dissipates little power in the saturated state and the off state compared to the semiconducting state (active region). Other advantages include smaller size and lighter weight (from the elimination of low frequency transformers which have a high weight) and lower heat generation from the higher efficiency. In this regard,
lighting device 200 exhibits higher efficiency and improved performed over other types of accent lighting.FIG. 3 illustrates a perspective view of thelighting device 200 ofFIG. 2 in an assembled configuration. - The components as previously described may comprise an embodiment of a lighting device according to the invention.
Lighting device 200 may be adapted to fit virtually any commercially available light fixture including, but not limited to, track lights, incandescent lighting fixtures, recessed can lighting, uplights or spot lights. In one embodiment, an adapter ring (not shown) may be used in conjunction withlighting device 200 to facilitate the connection oflighting device 200 with any of the available light fixtures previously mentioned. -

At a proximal end, tracklight fixture 422 includes a housing bottom 424,foam 426 and an O-ring 428.Foam 426 and O-ring 428 fit within housing bottom 424. At a distal end, tracklight fixture 422 includes aglass component 430 and ahousing top 432. In one embodiment, alighting device 400 is situated between the proximal end oftrack light fixture 422 and the distal end oftrack light fixture 422. The proximal end ofwire 418 may be electrically coupled to electrical circuitry withintrack light fixture 422. When power is supplied thereto, the composite light apparatus, i.e.,light device 400 and tracklight fixture 422 in this particular embodiment, may project a static or movable (i.e., animated) star field (i.e., pin-point lights) and/or static or movable clouds. The stars may be any color; in one embodiment, the stars of the star field are green. Additionally, the clouds may be any color such as, but not limited to, red, orange, green, cyan, sky blue, royal blue and/or white. In one embodiment,lighting device 400 has dimming capabilities.FIG. 5 illustrates a perspective view of the lighting device ofFIG. 3 within a track lighting fixture. -

In some embodiments, a tinted frit (not shown) is positioned within the light path of laser 602 thereby imparting color to the resulting light emanating from laser 602. The components described, i.e., housing 634 (including all sub-components, if any) andlaser cap 612 include an opening through their centers so that light emanating from laser 602 passes through to the external environment. This feature allows the light emanating from laser 602 to pass throughHOE 608 without interference from these supporting components, i.e.,laser cap 612 andhousing 634. - In one embodiment,
heatsink 604 may be affixed to aplate 636 byscrews 616 or any other suitable fastening means. In turn,plate 636 may rest within afirst recess 638 a of asecond heatsink 640.Second heatsink 640 may have a hemispherical-like configuration; however, other suitable configurations are within the scope of the invention.Second heatsink 640 may have abottom end 640 a (i.e., a first end) having a first diameter and a top end 640 b (i.e., a second end) having a second diameter wherein the first diameter is smaller than the second diameter.
