Technical field
This theme is related to general lighting and relate more specifically to for example can be in the room used in parking lot and parking structure
Outer and/or enclosed construction luminaire.
Background technology
The open space (platform in such as parking lot or garage parking) in big region needs enough illuminations to allow vehicle
All pacify (during reducing including natural illumination, such as night, the weather condition rained or have mist) at any time with people
The space is passed through entirely.Luminaire for motor pool or the landing for having top must be irradiated near luminaire
Big regional space controls dazzle in order to avoid disperseing the attention of driver simultaneously.Further, this luminaire sets in illumination
It 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 and
Other power and opposing weathering, it is necessary to enough gently allowing to be easily installed.In addition, this luminaire should be attractive in appearance
On make us pleasing.
The progress of light emitting diode (LED) technology result in the widely used of the luminaire including this equipment.Although
LED 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 as
Lens, 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 guides
The 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 to
It is adjusted to be interacted with subsequent component in (one or more) distributed component and to light.One or more point
How cloth element control light passes through waveguide and how to depend on waveguide geometry structure and material.(one or more) extracts unit
Part 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 injection
The position of the light in waveguide；And control light is angular distribution in Coupling optics.The spatial diffusion of control institute injection light
It 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 couple
There is the air gap between optics, or these lens can be by the same of (one or more) distributed component for limiting waveguide
One block of material is manufactured.Discrete Coupling optics allow many advantages, the coupling of such as higher efficiency, from the luminous flux in source
Controlled OverLap and the light that the injected how Angle ambiguity interacted with remaining element of waveguide.Discrete Coupling optics
The 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 design
With 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 fiber
Cable only little by little bends, and avoids the abrupt bend in waveguide.According to known total internal reflection principle, if incident illumination is not
More 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 penetrated
Line 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 point
The special angle of degree clash into refractive index interfaces surface (or, equally, until light ray exceedes relative to incident with light ray
The angle of the tangent line measurement of surface point), and light ray effusion.

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 with
Narrow (collimation) angular light distribution.In the case of parabola, therefore big optics is generally needed to realize high collimation
Level.In order to realize big emitting area in more compact design, prior art relies on the use of Fresnel lens, Fresnel lens
Light is guided using refracting optical surfaces and is collimated.However, Fresnel lens is generally inherently plane, and because
This 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 invention
In, optically coupling to optics in, wherein TIR is primarily used to redirect and collimates.The coupling allows to make from the whole of source
Angular 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 more
Controlled mode controls and extracts light.In standard fiber waveguide, light is rebounded back and forth by waveguide.In the present embodiment, in single
Light 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, but
It is that in identical or other embodiments, people may also want to other in control light ray or all to increase its role
Dissipate 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.
