Description
Technical field
The utility model relates to field of illuminating lamps, say more specifically a kind of be arranged on light source behind, for catoptrical reflector.
Background technology
Reflector claims again reflection shield, refers to light fixture in use, and what light source was sent can not impinge upon a kind of reflective utensil that the light on work and life face reflects.Mainly be used in U-shaped or helical type energy conserving lamp, fluorescent lamp, street lamp, LED lamp, Non-polarized lamp etc.Reflection shield is a kind of reflector often using, and can greatly improve the utilization rate of the light of light fixture, and Luminaire efficiency is improved greatly.The reflecting rate of reflector depends primarily on material, and for example reflectorized material reflecting rate is high, light decay etc. directly determines the quality of reflector.The shape of reflector, mainly refers to the reflection angle of light etc., has determined the disposal ability of reflector to the non-direct light of light source.Comprehensive, the material of reflector and shape have determined delivery efficiency and the output light flux of light fixture.Correct anode oxidation process can be brought into play the function of aluminium anode oxide film completely, its reflector efficiency can be brought into play completely, 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, has accurate technical indicator to monitor.
Therefore, the at present design of reflector mainly concentrates on how luminous intensity distribution reasonable in design is to be suitable for user's specific requirement for the shape of light source and application.For the requirement of illumination, according to the difference in the field of use, require also difference, some requires highlighted illumination, and some needs Uniform Illumination, and some need to realize illumination etc. in certain angle.With regard to the light distribution requirements in current most fields, major requirement has requirements such as far as possible reducing light loss and the uniformity.For this reason, most reflectors cross section adopts parabolical shape, and according to theory analysis, when light source is placed in parabolical focus, the direction of light after reflection on reflector is parallel, can form the hot spot that the uniformity is higher.But except reverberation, also have direct light, the luminous flux of direct light therefrom mind-set weakens outward, particularly marginal portion light a little less than, reverberation mainly concentrates on core, has greatly strengthened the luminous flux of spot center.So just, can outside the hot spot irradiating, form the aperture that a circle has obvious boundary, the amplitude that brightness changes too greatly, or on space, exist extreme contrast, so that cause ability uncomfortable or reduction observation important objects, it is so-called dazzle, this is that a lot of lighting apparatus are unallowed, should give to avoid in lighting apparatus design process as far as possible.
Utility model content
This technical problem to be solved is the above-mentioned defect that overcomes existing reflector, designs a kind of light of light source that can make and can be evenly distributed in certain region, forms the reflector of uniform hot spot.
The utility model is achieved through the following technical solutions above-mentioned purpose.
The utility model has designed a kind of reflector, it is wide at the top and narrow at the bottom bell that longitudinal section is, and has curved wall, and top is openend, bottom centre is used for installing light source, it is characterized in that described reflector from bottom upwards the curved wall vertical section of 1/3 height be shaped as hyperbola.In reflector design, otherwise it is almost impossible that the prerequisite of loss luminous flux is avoided dazzle completely, a lot of reflectors are the mode that adopts again luminous intensity distribution substantially, reduce the energy of dazzle part as far as possible, can focus on hot spot, but dazzle still exists, be size or no obvious problem.The utility model adopts completely new concept to design reflector, allow the formed facula area of light reflecting through reflector more greatly, more approach the formed facula area of direct projection light, can make like this luminous flux distribute more uniformly in whole hot spot, elimination, because of the too large formed dazzle of brightness amplitude of variation, makes full use of light source.This patent adopts hyp Yi Ge branch as the pattern curve of the longitudinal cross-section of reflector, according to theory analysis, the light source being arranged in hyperbola Yi Ge branch focus is intersected in the focus of another branch of hyperbola through the reverse extending line of the light of hyperbola reflection, therefore the area of the formed hot spot of light after reflector reflection is able to uniform expansion, forms hot spot complete and that be evenly distributed with direct light line.The parabolical reflector of available technology adopting, although also can adjust the position of light source in reflector, expands the light of reflection, and the also synchronous expansion of such direct projection light, still cannot solve the problem of dazzle.In actual applications, according to rising angle, further adjust bent curvature of a curve and hyp height, distribute the energy of reflection ray and direct projection light, can make the further uniform distribution of luminous energy on whole hot spot.
As concrete application, the shape of described reflector can be bell for integral body, curved wall is the surfaces of revolution, and from bottom, upwards the curved wall of 1/3 height is the curved surface that the rotation of hyperbola one branch forms, and described light source is for being arranged on the locational spot light of hyperbolic focus.Or described reflector integral body is elongated, curved wall is arcuate flanks, from bottom, upwards the curved wall of 1/3 height is the curved surface that hyperbola one branch extends along strip direction, and described light source is to be arranged on the locational line source extending along strip direction of hyperbolic focus.Spot light described herein and line source are not spot light and the line sources of theoretical ideal, in actual applications, described spot light refers to the concentrated illuminators of point such as U-shaped or helical type energy conserving lamp, LED lamp, Non-polarized lamp, described line source is the concentrated illuminator of line such as light modulation, LED fluorescent tube in a few days, all has certain volume.Due to and nonideal spot light and line source, therefore in actual applications, according to the requirement of the concrete light angle of emergence, its concrete position can be focal position, a little less than or higher than focal position, all can.
According to concrete light distribution requirements, under the fixed prerequisite of shooting angle, in order to make light be uniformly distributed on hot spot as far as possible, the hyperbola part of reflector should take whole reflector larger area, and therefore reflector described in the utility model is for from bottom, upwards 2/3 height or whole curved wall vertical section are shaped as hyperbola one branch.
Hyp shape is varied, is not the use that any hyp shape is all applicable to optimize reflector, and in order to make the light flux distribution on hot spot even, the parametric equation of described hyperbola face is as follows:
x=a*tan(t)
y=b*sec(t)
15<a<140 wherein, 25<b<500, a<b, and b:a=1.1 ~ 4.0,0 ° of <t<90 °.
Adopt the hyp reflector of above-mentioned parameter can be applicable to existing most of reflector, make on the hot spot after reflector reflection light flux distribution even.
In practical application, according to the difference of rising angle, above-mentioned parameter is distinguished to some extent, and the uniformity of hot spot is further optimized, and for conventional rising angle, utility model people, through a large amount of test and contrast, selects following Optimal Parameters:
For reflector rising angle, be 8 ~ 20 degree, 45<a<150 wherein, 110<b<500, and b:a=1.5 ~ 4.0;
For described reflector rising angle, be 25 ~ 40 degree, 15<a<120 wherein, 25<b<210, and b:a=1.1 ~ 2.0.
Rising angle described in this patent adopts the definition of European standard, i.e. half of the angle of half and light source line of highlight flux (the next center light flux of ordinary circumstance) on lighting apparatus light intensity distribution map.Adopt other definition, such as Unite States Standard, etc., may distinguish to some extent with this patent, but all can convert European standard to, define, do not affect the qualitative of this patent.
For simplified design, the curved wall inner surface of this patent is provided with multilayer reflective plane, and multilayer reflective plane distributes along curved wall curved surface, fits to curved wall curved surface.The curved design of reflector is the basis based on theoretical substantially, in practical application and processing, the inner surface of reflector seldom directly adopts camber line, because directly adopt the drop point of camber line light of each point reflection in computer simulation computing all different, to greatly increase amount of calculation, be unfavorable for actual design.For making to design further design processes simplified, and can carry out fast counter control to result of design, this patent adopts the structure of plane fitting curved surface to substitute the structure of complete curved surface.The drop point of the light that each face reflects is like this definite, and plane is limited, and computer can carry out processing at a high speed and simulate.
For above-mentioned two kinds of conventional reflectors, when described reflector integral body is bell, every layer of reflective plane ringwise, formed along annular spread matching by a plurality of reflective sub-planes; Elongated when described reflector integral body, every layer of reflective plane is the plane of extending along strip direction.High for designing requirement, concerning the high lighting apparatus of the uniformity requirement of hot spot, can increase the quantity of fit Plane, the quantity of matching is more, and its global shape more approaches curved surface.
According to the distribution density of reflector interior lights, the position luminous flux that more approaches light source is larger, therefore need to its adjust and the required precision that distributes higher, otherwise lower, 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.Therefore, as the utility model, whole curved wall vertical section is shaped as hyperbola one branch, and described reflective plane progressively increases from bottom to top area.This design meets the distribution of light in reflector, for the large part of luminous flux, adopt the plane of a plurality of small sizes to adjust, for the little part of luminous flux, adopt relatively few large-area planar to adjust, can further optimize like this light uniformity of hot spot.
For the larger reflecting surface of area, although total light intensity is not necessarily very large, because the area of the light of its reflection is larger, in order to be uniformly distributed, the reflective area of adjacent layer does not answer gap excessive, otherwise likely causes luminous intensity distribution inhomogeneous yet.Therefore the reflective sub-area of plane of this patent in every layer is identical, and bottom is upwards more than 1/2 height, and the sub-plane that any adjacent two-layer reflective plane is corresponding is no more than 20% in the difference of reflector projected area transversely.At this, adopt the projected area of light after reflecting surface reflection and do not adopt real area, this is that the light that reflected concentrates in view field due to the projected area that forms hot spot and depend primarily on reflective surface.The larger region of reflecting surface in reflector, refer generally in bottom upwards region more than 1/2 height, the projected area of adjacent layer is larger, general institute reflection flux is larger with regard to difference, in order to improve the uniformity, have gradually changing of reflecting surface area concurrently simultaneously, the reflective sub-area of plane of this patent in requiring every layer is identical, the sub-plane that any adjacent two-layer reflective plane is corresponding is no more than 20% in the difference of reflector projected area transversely, and from bottom to top increases gradually.
The utility model is the luminous flux uniformity of the hot spot of appropriate design lighting apparatus for how, by adopting hyperbolic shape to substitute the reflector of traditional parabolic structure, make the light of light source through expanding equably after reflection, form uniform hot spot with direct projection light partial stack, eliminate dazzle.And by optimizing the curve of reflector, make luminous flux rationally stack in hot spot of reflector reflection, further optimize the uniformity of hot spot.For simplified design, under existing all-purpose computer computing capability prerequisite, can carry out simplation verification to the reflector designing, shorten the design cycle, make Theoretical Design can be able to practical application.This patent adopts the structure of plane fitting curved surface under the prerequisite of error license, to substitute complete curved-surface structure, and the flexibility that has improved structural design makes Theoretical Design and the Experience Design can be in conjunction with, phase mutual induction card.With respect to prior art, the art of this patent not only uniformity of hot spot is higher, and dazzle is farthest reduced, and as the use of illumination, makes light source be able to sufficient utilization, improves light utilization efficiency, therefore has outstanding substantial effect and significant progressive.
