Background technology
The open space (platform in such as parking lot or garage parking) in big region needs enough illuminations to allow vehicleAll pacify (during reducing including natural illumination, such as night, the weather condition rained or have mist) at any time with peopleThe space is passed through entirely.Luminaire for motor pool or the landing for having top must be irradiated near luminaireBig regional space controls dazzle in order to avoid disperseing the attention of driver simultaneously.Further, this luminaire sets in illuminationIt is standby to may be mounted in various closings and non-close position, on electric pole or surface in the sense that (such as, garage ceiling)It is general, and uniform outer appearance is preferably presented.
Additionally, for irradiate parking lot or parking structure luminaire must have firm construction with bear wind andOther power and opposing weathering, it is necessary to enough gently allowing to be easily installed.In addition, this luminaire should be attractive in appearanceOn make us pleasing.
The progress of light emitting diode (LED) technology result in the widely used of the luminaire including this equipment.AlthoughLED can be only used for producing light in the case where auxiliary optical equipment is not needed, it has however been found that optics corrector is (such asLens, reflector, fiber waveguide and combinations thereof) illumination distribution of application-specific can be significantly improved.
Fiber waveguide makes the light mixing sent by one or more light source (such as, one or more LED) and guidesThe light sent by one or more light source.Typical fiber waveguide includes three primary clusterings:One or more coupling element,One or more distributed component and one or more extraction element.(one or more) coupling assembly is directed light toIt is adjusted to be interacted with subsequent component in (one or more) distributed component and to light.One or more pointHow cloth element control light passes through waveguide and how to depend on waveguide geometry structure and material.(one or more) extracts unitPart is by controlling light wherein and determining how removal light in the upward out waveguide of what side.
It is main to consider when Coupling optics are designed:Light is set to maximize from the efficiency that source is delivered to waveguide;Control injectionThe position of the light in waveguide;And control light is angular distribution in Coupling optics.The spatial diffusion of control institute injection lightIt is by making each source with special lens-adapter with a kind of mode of angular spread.These lens could be arranged to lens with coupleThere is the air gap between optics, or these lens can be by the same of (one or more) distributed component for limiting waveguideOne block of material is manufactured.Discrete Coupling optics allow many advantages, the coupling of such as higher efficiency, from the luminous flux in sourceControlled OverLap and the light that the injected how Angle ambiguity interacted with remaining element of waveguide.Discrete Coupling opticsThe distribution of light being injected in waveguide is controlled using refraction, total internal reflection and surface or volume scattering.
After in optically coupling to waveguide, it is necessary to be conducted and adjust to extraction position.Simplest example is designWith minimal losses light to be delivered to into the fiber optic cables of the other end from one end of cable therebetween.To achieve it, optical fiberCable only little by little bends, and avoids the abrupt bend in waveguide.According to known total internal reflection principle, if incident illumination is notMore than the critical angle relative to surface, then the light for being advanced through waveguide is reflected back in waveguide from waveguide outer surface.Specifically, light is penetratedLine continues the traversal through waveguide, until this ray is with less than the angle relative to the line measurement perpendicular to light ray incidence surface pointThe special angle of degree clash into refractive index interfaces surface (or, equally, until light ray exceedes relative to incident with light rayThe angle of the tangent line measurement of surface point), and light ray effusion.
In order that extract element removes light from waveguide, light must first contact the part including the extraction element.By makingWaveguide surface suitably shapes, and people can control the flowing of the light by (one or more) extracting parts.Specifically, selectSelect spacing, shape and (one or more) further feature of extracting parts to affect outward appearance, its distribution for producing of waveguideAnd efficiency.

Extracting parts disclosed herein efficiently extracts light from waveguide.At least some in luminaire disclosed herein is specialIt is not suitable for using in an installation, such as stand-by lamp or renewal lamp, exterior product (for example, street lamp, overhead lamps, ceiling light)(for example, the surface on Down lamp, troffer, the application of embedded either plug-in type, wall or ceiling is installed and is answered with interior productsWith etc.), the general ambient light equipment for preferably needing at least about 800 lumens or bigger is exported, and, in some embodimentsIn, the general ambient light equipment output of at least about 7000 lumens is (although the dependence of general ambient light equipment output par, c ground certainly should in expectationWith).Additionally, luminaire disclosed herein preferably have between about 2500 degree Kelvins and about 6200 degree Kelvins, withAnd more preferably between about 2500 degree Kelvins and about 5000 degree Kelvins and most preferably about 4000 degree Kelvins withColour temperature between about 5000 degree Kelvins.Additionally, at least some in luminaire disclosed herein is preferably presented at least bigAbout 100 lumens/watts, and the more preferably at least efficiency of about 120 lumens/watts.Additionally, optical coupled component disclosed hereinAt least about 90% aggregate efficiency is preferably presented with least some in waveguide, and (that is, the light for extracting from waveguide is divided by being injected intoLight in waveguide).At least about 70 color rendition index (CRI) is preferably by least some in luminaire disclosed hereinObtain, wherein more preferably at least about 80 CRI.Any desired specific output light distribution (such as, butterfly can be realizedLight distribution), including the either only upper distribution or only lower distribution etc. of upper and lower light distribution.
When people are using being transmitted into the relative of wider (for example, lambert) angular distribution (common for LED-based light source)During compared with small light source, as commonly understood in the art, divergence conservation need the optical system with big emitting area with realize compared withNarrow (collimation) angular light distribution.In the case of parabola, therefore big optics is generally needed to realize high collimationLevel.In order to realize big emitting area in more compact design, prior art relies on the use of Fresnel lens, Fresnel lensLight is guided using refracting optical surfaces and is collimated.However, Fresnel lens is generally inherently plane, and becauseThis is poorly suited for the wide-angle light to being launched by source and redirects, and causes optical efficiency to be lost.Conversely, in the present inventionIn, optically coupling to optics in, wherein TIR is primarily used to redirect and collimates.The coupling allows to make from the whole of sourceAngular emission scope (including wide-angle light) is redirected and collimated, and produces light efficiency higher in more compact form factor.
In in the present embodiment at least some, the distribution of the light in waveguide and direction are known, and thus, with moreControlled mode controls and extracts light.In standard fiber waveguide, light is rebounded back and forth by waveguide.In the present embodiment, in singleLight is extracted during by waveguide as much as possible so that loss is minimized.
In certain embodiments, people may wish to control light ray, so that at least some in ray is collimated, butIt is that in identical or other embodiments, people may also want to other in control light ray or all to increase its roleDissipate so that this light is not collimated.In certain embodiments, people may wish to collimation to close limit, and in other cases,People may wish to carry out contrary.
