Description
Technical field
The present invention relates to field of illuminating lamps, be in particular a kind of be arranged on light source behind, for reflecting the reflector of light.
Background technology
Reflector, also known as reflection shield, refers to light fixture in use, the reflective utensil of one that the light that can not impinge upon on work and life face sending light source reflects.Mainly it is used in U-shaped or helical type energy conserving lamp, daylight lamp, street lamp, LED, Non-polarized lamp etc..Reflection shield is commonly used a kind of reflector, can be greatly improved the utilization rate of the light of light fixture, makes Luminaire efficiency be greatly improved.The reflecting rate of reflector depends primarily on material, and such as reflectorized material reflecting rate height, light decay etc. directly determine the quality of reflector.The shape of reflector, refers mainly to the reflection angle etc. to light, determines the disposal ability of reflector direct light non-to light source.For Zong He, the material of reflector and shape determine delivery efficiency and the output light flux of light fixture.Correct anode oxidation process can play the function of aluminium anode oxide film completely, can be brought into play completely by its reflector efficiency, improve reflector reflective and reliability.Under current technical conditions, the anode oxidation process comparative maturity of reflector, from electrochemical polish, coating film treatment to hole sealing technology, there is accurate technical specification to be monitored.
Therefore, the design of current reflector focuses mainly on the shape of light source and applies luminous intensity distribution the most reasonable in design to be suitable for the specific requirement of user.For the requirement of illumination, according to the difference in the field of use, it is desirable to also different, some requires illumination highlights, and some needs Uniform Illumination, and some needs realizes illumination etc. in certain angle.For the light distribution requirements in most fields, major requirement has the minimizing requirement such as light loss and the uniformity as far as possible.To this end, most reflector cross sections use parabolical shape, according to theory analysis, when light source is placed in parabolical focus when, light direction after reflection on reflector is parallel, it is possible to form the hot spot that the uniformity is higher.But in addition to reflection light, also direct light, the luminous flux of direct light outwards weakens from center, and particularly marginal portion light is more weak, and reflection light is concentrated mainly on core, has been greatly reinforced the luminous flux of spot center.So will form a circle outside the hot spot irradiated and there is the aperture of substantially boundary, the amplitude of brightness flop is the biggest, or spatially there is extreme contrast, so that causing uncomfortable or reducing the ability observing important objects, the most so-called dazzle, this is that a lot of luminaire is unallowed, should give and avoid as far as possible during lighting device design.
Summary of the invention
This to be solved technical problem is that the drawbacks described above overcoming existing reflector, designs a kind of light that can enable light source and is evenly distributed in certain region, forms the reflector of uniform hot spot.
The present invention is achieved through the following technical solutions above-mentioned purpose.
The present invention devises a kind of reflector, longitudinal section is wide at the top and narrow at the bottom bell, has curved wall, and top is opening, bottom centre is used for installing light source, it is characterised in that the curved wall vertical section of described reflector 1/3 height bottom-up is shaped as hyperbola.In reflector designs, otherwise the premise of loss luminous flux avoids dazzle to be nearly impossible completely, a lot of reflectors substantially use again the mode of luminous intensity distribution, reduce the energy of dazzle part as far as possible, can focus on hot spot, but dazzle still exists, simply size or the most significantly problem.The present invention uses completely new concept to design reflector, the facula area that the facula area i.e. allowing the light reflected through reflector be formed is bigger, formed closer to direct projection light, luminous flux so can be made to distribute more uniformly in whole hot spot, eliminate because of the biggest the formed dazzle of brightness flop amplitude, make full use of light source.This patent uses a hyp branch as the pattern curve of the longitudinal cross-section of reflector, according to theory analysis, the reverse extending line of the light that the light source being arranged in one branch's focus of hyperbola reflects through hyperbola is intersected in the focus of another branch of hyperbola, therefore the area of the hot spot that the light after reflector reflects is formed is expanded uniformly, forms hot spot that is complete and that be evenly distributed with direct light line.Prior art uses parabolical reflector, although light source position in reflector can also be adjusted, make the light of reflection expand, but the expansion that so direct projection light also synchronizes, the problem that still cannot solve dazzle.In actual applications, bent curvature of a curve and hyp height, distribution reflection light and the energy of direct projection light, it is possible to make the further uniform distribution of the luminous energy on whole hot spot are adjusted further according to rising angle.
As concrete application, the shape of described reflector can be overall bell-like, curved wall is the surfaces of revolution, and the curved wall of 1/3 height is the curved surface that hyperbola one branch rotates bottom-up, and described light source is the point source being arranged on hyperbolic focus position.Or described reflector entirety is elongated, curved wall is arcuate flanks, the curved wall of 1/3 height is the curved surface that hyperbola one branch extends along strip direction bottom-up, and described light source is the line source extended along strip direction being arranged on hyperbolic focus position.Point source described herein and line source are not point source and the line sources of theoretical ideal, in actual applications, described point source refers to that U-shaped or helical type energy conserving lamp, LED, Non-polarized lamp etc. put the luminous body concentrated, the luminous body that the described line source in a few days line such as light modulation, LED lamp tube is concentrated, is respectively provided with certain volume.Due to and nonideal point source and line source, the most in actual applications, according to the requirement of the concrete light angle of emergence, its concrete position can be focal position, slightly below or higher than focal position.
According to concrete light distribution requirements, on the premise of shooting angle is fixed, in order to make light be uniformly distributed on hot spot as far as possible, the hyperbola branch of reflector should take whole reflector larger area, and reflector the most of the present invention is that 2/3 height or whole curved wall vertical section are shaped as hyperbola one branch bottom-up.
Hyp shape is varied, and the most any hyp shape is all applicable to optimize reflector and is used, so that the light flux distribution on hot spot is uniform, the parametric equation in described hyperbola face is as follows:
x=a*tan(t)
y=b*sec(t)
Wherein 15 < a < 140,25 <b < 500, a <b, and b:a=1.1 ~ 4.0,0 ° < t < 90 °.
The hyp reflector using above-mentioned parameter can be applicable to existing major part reflector, makes light flux distribution on the hot spot after reflector reflects uniform.
On reality is applied, according to the difference of rising angle, above-mentioned parameter is otherwise varied so that the uniformity of hot spot is optimised further, and for conventional rising angle, inventor, through substantial amounts of test and contrast, selects following parameters optimization:
It is 8 ~ 20 degree for reflector rising angle, wherein 45 < a < 150,110 <b < 500, and b:a=1.5 ~ 4.0；
It is 25 ~ 40 degree for described reflector rising angle, wherein 15 < a < 120,25 <b < 210, and b:a=1.1 ~ 2.0.
Rising angle described in this patent uses the definition of European standard, i.e. the half of half and the angle of light source line of highlight flux (ordinary circumstance bottom center luminous flux) on luminaire light intensity scattergram.Other are used to define, such as Unite States Standard, etc., may be otherwise varied with this patent, but all can be converted into European standard and be defined, have no effect on the qualitative of this patent.
In order to simplify design, the curved wall inner surface of this patent is provided with multilamellar reflective plane, and multilamellar reflective plane arcuately sidewall curved surface is distributed, and fits to curved wall curved surface.The curved design of reflector is substantially based on the basis of theory, in reality application and processing, the inner surface of reflector the most directly uses camber line, because directly using camber line drop point of the light of each point reflection in computer simulation computing the most different, amount of calculation will be greatly increased, be unfavorable for actual design.For making to design further design processes simplified, and result of design can be rapidly performed by counter control, this patent uses the structure of plane fitting curved surface to substitute the structure of complete curved surface.The drop point of the most each the light reflected is and determines, and plane is limited, and computer can carry out process at a high speed and be simulated.
For for the reflector that above two is conventional, when described reflector entirety is bell-like, every layer of reflective plane ringwise, is formed by multiple reflective sub-plane annularly fittings of distribution；When described reflector entirety is elongated, every layer of reflective plane is the plane extended along strip direction.Requiring height for design, for the luminaire high to the uniformity requirement of hot spot, can increase the quantity of fit Plane, the quantity of matching is the most, and its global shape is closer to curved surface.
For distribution density according to reflector interior lights, position luminous flux closer to light source is the biggest, it is thus desirable to it is adjusted and the required precision that distributes is the highest, otherwise it is the lowest, in the reflector of arc, light source is arranged on the bottom of reflector, and reflector inner surface is from bottom to top increasing with the distance of light source.For the present invention, whole curved wall vertical section is shaped as hyperbola one branch, and described reflective plane incrementally increases to top area from bottom.This design meets light distribution in reflector, uses the plane of multiple little areas to be adjusted for the part that luminous flux is big, uses relatively little of large-area planar to be adjusted for the part that luminous flux is little, so can optimize the light uniformity of hot spot further.
For the reflecting surface that area is bigger, although total light intensity is the biggest, but owing to the area of its light reflected is relatively big, in order to be uniformly distributed, the reflective area of adjacent layer does not answer gap excessive, is otherwise also possible to cause luminous intensity distribution uneven.Therefore this patent reflective sub-area of plane in every layer is identical, more than bottom up 1/2 height, sub-plane corresponding to any adjacent two-layer reflective plane in the difference of reflector projected area transversely less than 20%.Use light projected area after reflective surface not use real area at this, this is the projected area depending primarily on reflective surface owing to forming hot spot, and the light i.e. reflected concentrates in view field.The region that reflecting surface in reflector is bigger, refer generally to the region more than bottom up 1/2 height, the projected area of adjacent layer is the biggest, general institute reflection flux is the biggest with regard to difference, in order to improve the uniformity, having gradually changing of reflecting surface area concurrently, the reflective sub-area of plane in this patent requires every layer is identical simultaneously, sub-plane corresponding to any adjacent two-layer reflective plane, and is from bottom to top gradually increased less than 20% in the difference of reflector projected area transversely.
The present invention be directed to the luminous flux uniformity of the how hot spot of appropriate design luminaire, by using hyperbolic shape to substitute the reflector of traditional parabolic structure, the light making light source can expand after reflection equably, form uniform hot spot with direct projection light partial stack, eliminate dazzle.And by optimizing the curve of reflector, make luminous flux reasonable superposition in hot spot that reflector reflects, optimize the uniformity of hot spot further.In order to simplify design, under existing general purpose computer computing capability premise, it is possible to the reflector designed is simulated checking, shorten the design cycle, enable Design Theory to be used practically.This patent uses the structure of plane fitting curved surface to substitute complete curved-surface structure on the premise of error is permitted, improves the motility of structure design, enables Design Theory and Experience Design to combine, and phase mutual induction is demonstrate,proved.Relative to prior art, the uniformity of the art of this patent not only hot spot is higher, and dazzle is farthest reduced, and is used as illumination so that light source is sufficiently utilized, and improves light utilization efficiency, therefore has prominent substantial effect and significantly progress.
