Summary of the invention
The purpose of this invention is to provide a kind of LED lamp distribution Module Design method that can hang down damage ground formation rectangular light spot.
For this reason, in the LED lamp distribution Module Design method provided by the invention, this LED lamp distribution module comprises substrate, be packaged with led chip on the substrate, along on the direction of illumination of led chip dodging and beaming reflector being set, the dodging and beaming reflector light direction is provided with the beam shaping beam expander made from the high transmission rate material, the one side that the beam shaping beam expander has towards dodging and beaming reflector is provided with the plane of incidence and the relative exit facet that simultaneously is provided with the plane of incidence, this method comprises according to the illumination requirement of face to be illuminated with environmental requirement determines the position of led chip and the convergent angle of dodging and beaming reflector, and the light that led chip is sent is divided into the grid that a plurality of areas equate through the isolux behind the dodging and beaming reflector, will also be divided into the grid that same a plurality of area equates according to the road surface; Distribute and lighting requirement determines that light that led chip sends is through the maximum beam angle behind the dodging and beaming reflector according to light, set up the grid of face to be illuminated and the corresponding relation between the grid of road surface, and calculate the angle of the light needs deflection of led chip according to the refractive index of beam shaping beam expander material, curve according to light distribution situation and maximum beam angle calculating beam shaping beam expander at first direction, on the second direction vertical, carry out cylinder again and extend, obtain the curve form of the plane of incidence and exit facet with first direction.
In the LED lamp distribution module by the said method design, the light that dodging and beaming reflector can send led chip is converged in the less beam angle, and, control the maximum beam angle of beam projecting in the design process by dodging and beaming reflector, the light-ray condensing that sends of led chip penetrates in the dead ahead of led chip like this, form the hot spot of rectangle again by the refraction of beam shaping beam expander, thereby meet the requirement of face to be illuminated, prevent the generation of dazzle and the waste of minimizing light.
A preferred scheme is, in the step of the grid of setting up face to be illuminated and lattice relationship by light isolux behind the dodging and beaming reflector, equates to be condition with the take up an official post luminous flux of equiluminous veil lattice of face to be illuminated with the luminous flux of face to be illuminated grid.
This shows, LED lamp distribution module according to above-mentioned condition setting, can guarantee the uniform directive of the light road surface that led chip sends, thereby guarantee to be subjected to light even according to the road surface, avoid on the road surface, forming lighted region at interval and dim zone, help driver and pedestrian and see the road surface situation clearly.
Further scheme is, in the step of calculating the plane of incidence and exit facet, on first direction, being incident to behind the beam shaping beam expander from the edge that exit facet shines the road surface grid with the light of maximum beam angle outgoing is that the border of first direction is a condition, in second direction, being incident to behind the beam shaping beam expander from the edge that exit facet shines road surface second direction grid with the light of maximum beam angle outgoing is that the border of second direction is a condition.
By above-mentioned boundary condition, to calculate at first direction, light is separated at aspheric one group, and this is separated is two curves, and the physical significance of this two curve is that Ray Of Light passes through to arrive on the predetermined grid of face to be illuminated after the refraction of the optically denser medium between this curve.Separate according to first group, go out the N group with the continuous iterative computation of iterative method and separate, till another border.Because what calculate separates all within the border of maximum beam angle, so after the light process aspheric surface, light can not have the scope that light exceeds grid by aspheric steering handle light refraction to the face to be illuminated of required illumination.
Further scheme is again, and the middle part of the plane of incidence constitutes the cylinder to the body recess of beam shaping beam expander, and exit facet has the cambered surface to light exit direction projection, and the center line face of cylinder and the center line face of cambered surface are overlapping.As seen, the light that enters lens is during from the cambered surface outgoing, and incidence angle is less, can avoid the generation of total reflection phenomenon, thereby reduces the loss of light in lens medium.

Dodging and beaming reflector 20 has perisporium 21, and the upper end of perisporium 21 is a light inlet 22, and light inlet 22 can be fixed on the substrate, and led chip is encapsulated in the light inlet 22.An end relative with light inlet 22 is light-emitting window 23, and the light that led chip sends outwards penetrates through light-emitting window 23.
Below dodging and beaming reflector 20, just the direction of illumination that emits beam of led chip is provided with beam shaping beam expander 30.Beam shaping beam expander 30 is fixed in the lampshade by syndeton and forms sealing, and its structure as shown in Figure 3.
Beam shaping beam expander 30 has body 31, and the upper surface of body 31 is the plane of incidence 32, and just the plane of incidence 32 is provided with towards dodging and beaming reflector 20.The middle part of the plane of incidence 32 is provided with the non-spherical cylinder 33 to body 31 sunken insides, and non-spherical cylinder 33 runs through the pair of sidewalls of body 31.By Fig. 3 and Fig. 4 as seen, two surfaces of non-spherical cylinder 33 are respectively inclined-plane 34 and inclined-plane 35, can be incident on inclined-plane 34 or the inclined-plane 35 through the light of dodging and beaming reflector 20 perisporiums 21 reflections, and be incident in the body 31.
Shown in Figure 3 is the cutaway view of beam shaping beam expander 30 on the xOz face, and beam shaping beam expander 30 is the cylinder bodies that stretching forms on the y direction of principal axis that are projected in along the xOz face.
The lower surface of body 31 is an exit facet 37, and exit facet 37 is oppositely arranged with the plane of incidence 32.Be provided with cambered surface 38 to light exit direction projection at the middle part of exit facet 37.Center line face 39 is overlapping with the center line face 36 of non-spherical cylinder 33.From the light of beam shaping beam expander 30 outgoing through cambered surface 38 outgoing.
Led chip 40 is positioned on the light inlet 22 of dodging and beaming reflector 20, light that led chip 40 sends through after the reflection of perisporium 21 from light-emitting window 23 outgoing, and be incident on two inclined- planes 34,35 of non-spherical cylinder 33, after passing through the refraction of beam shaping beam expander 30 again, from the exit facet 37 directive road surfaces of beam shaping beam expander 30.In the present embodiment, the axis of dodging and beaming reflector 20 is positioned on the center line face 36 of non-spherical cylinder 33, and led chip 40 also is positioned on the center line face 36 of non-spherical cylinder 33.

And, because beam shaping beam expander 30 projection in one direction is that one dimension is an aspheric surface, projection on other direction is a straight line, as shown in Figure 4, behind the light process beam shaping beam expander 30, light is evenly distributed in and is shone on the road surface, forms significantly the effect of " rectangle " hot spot uniformly.
When making the LED light fixture, need to make lamppost, lampshade etc., and the LED lamp distribution module of design and installation in lampshade.During design luminous intensity distribution module, at first according to lighting condition and lighting environment requirement, as the brightness of illumination requirement on road surface, the length of hot spot and the requirement of width requirement, led light source and road surface vertical range etc., determine position as the led chip and the dodging and beaming reflector of light source, determine that light that led chip sends through the maximum beam angle behind the dodging and beaming reflector, designs dodging and beaming reflector with this.The dodging and beaming reflector that present embodiment is designed, its method for designing can be the Chinese invention patent application of CN101900296A with reference to publication number.Certainly, also can use other method for designing to design reflective device.
Behind the design dodging and beaming reflector, can determine the maximum beam angle of light according to the width of face to be illuminated from the dodging and beaming reflector outgoing, as shown in Figure 4, light L1, L2 all are from the led chip outgoing, and the light of process dodging and beaming reflector lower limb, the angle α between light L1, the L2 is maximum beam angle.
Since the light that sends of led chip with the equidistant sphere of led chip on be that illumination equates, so the isolux of led chip approaches a hemisphere face.After the reflection by dodging and beaming reflector, isolux is a curved surface after the convergence.
During design luminous intensity distribution module, the isolux of light after by the dodging and beaming reflector light-emitting window is divided into a plurality of areas equates grid, as shown in Figure 5.Simultaneously, face to be illuminated also is divided into the grid that same a plurality of area equates, as shown in Figure 6, can requires to determine the sizing grid and the quantity of division when dividing grid according to the uniformity on road surface, grid is many more, and the uniformity of illumination is good more.Then, set up the grid of isolux and the grid corresponding relation of face to be illuminated.Wherein, the luminous flux of corresponding grid equates, when grid at y direction differential after to a certain degree, just become a line.Then, in the y direction this curve is carried out cylinder and extend, up to till another border on the y direction.
Relation according to road surface grid and isolux grid, can draw the angle of sending the needs skew of light beam from led chip, promptly, can calculate the curve form of light at the beam shaping beam expander plane of incidence and exit facet according to the refractive index of beam shaping beam expander material.
Certainly, when the design plane of incidence and exit facet, also need to consider through after entering the beam shaping beam expander with the light of maximum beam angle outgoing behind the dodging and beaming reflector, when refraction takes place, also can reflect, from the light of exit facet outgoing, avoid the reflected illumination that light takes place to arrive outside the predetermined road surface as far as possible, can avoid the loss of light energy like this and produce dazzle.
In addition, when the design plane of incidence and exit facet, need to be equated being condition with the arbitrary grid luminous flux of isolux by luminous flux according to arbitrary grid on the road surface, this realizes with the integral equality of quilt according to the road surface luminous flux by the luminous flux of setting up isolux.And, in the step of the curve form of the calculating plane of incidence and exit facet, also need be incident to behind the beam shaping beam expander from the edge that the light of exit facet outgoing shines face to be illuminated with the light of maximum beam angle outgoing is boundary condition, and this can realize by the curve form that changes the plane of incidence and exit facet.
By such scheme as seen, the light that led chip sends can be controlled in the less beam angle effectively, and light passes on the road surface that beam shaping beam expander and directive need illuminate, form rectangular light spot, light is soft comfortable to human eye simultaneously, harmless to human eye, no light pollution can form rectangular light spot in mode cheaply.And, above-mentioned method for designing has been considered by the actual illumination situation according to the road surface, be divided into grid by isolux with dodging and beaming reflector light-emitting window place, and will be divided into grid according to the road surface, luminous flux by corresponding grid equates to guarantee equated according to each grid place luminous flux on the road surface on the x direction of principal axis with on the y direction of principal axis, avoid on the road surface, forming the dark space, help driver and pedestrian and observe the road surface situation.
Certainly, the foregoing description only is a preferred version of the present invention, also has other variation during practical application, for example, use collector lens to substitute the light collecting device of dodging and beaming reflector as convergence, like this, led chip need be arranged on the optical axis of collector lens, and the center line face of the non-spherical cylinder of beam shaping beam expander also passes through the optical axis of collector lens, and such change also can realize purpose of the present invention.
It is emphasized that at last; the invention is not restricted to above-mentioned embodiment, also should be included in the protection domain of claim of the present invention as the change of the methods for designing such as type of the change of the change of the size of rectangular light spot, dodging and beaming reflector convergent angle, led light source.
