Embodiment
The C-planar system is a kind of measurement commonly used and the coordinate system of description light source or light fixture light distribution, and this system can be used in the luminosity measurement of led light source or light fixture.Under the C-planar system, the spatial light intensity of measuring and describe led light source or light fixture distributes, generally describe by distribution curve flux, and described distribution curve flux refers under polar coordinate system or rectangular coordinate system, the corresponding light intensity value of all angles on certain the luminous intensity distribution plane that marks, and the curve synoptic diagram that this light intensity value changes with angle is described out.Wherein, people pay close attention to and analyze is distribution curve flux on C0-C180 and these two luminous intensity distribution planes of C90-C270.
From distribution curve flux figure, the distribution curve flux on these two planes can overlap, and also can be diverse.The angle in 0 ° of angle line left side is positive-angle among the General Definition distribution curve flux figure, represent with "+", the angle on 0 ° of angle line right side is negative angle, represent with "-", then the distribution curve flux on each plane can make symmetrical expression, with respect to 0 ° of angle line left-right symmetric, also can be asymmetric namely, namely asymmetric with respect to 0 ° of angle line left and right sides.And, value that can the reading optical beam angle from the distribution curve flux, described beam angle refer to the angle sum that the angle that turns over when the largest light intensity angle line is rotated counterclockwise to 50% largest light intensity angle line on this distribution curve flux and this largest light intensity angle line dextrorotation turn over when going to 50% largest light intensity angle line.
In addition, in order to express easily, we will become the C0-180 cross section with the face of C0-180 luminous intensity distribution planes overlapping in the structure of led light source, become the C90-270 cross section with the face of C90-270 luminous intensity distribution planes overlapping, and C0-C180 cross section and C90-270 cross section are as the cutaway view plane of led light source structure.
Just as described in the background section, when the light fixture of available technology adopting once light-distribution technique was used for illumination, the utilance of luminous flux was lower; When the light fixture of employing secondary light-distribution technique was used for illumination, although the utilization of luminous flux promotes to some extent, its cost was higher, and the production operation complexity is also higher.Describe below in conjunction with concrete condition.
In street lighting, the inventor studies discovery, and common car lane is arranged as track, 2 track to 8, and wherein, some car lane also comprises central partition and greenbelt etc.And common lamp stand spread pattern has one-sided arrangement, Bilateral Symmetry to arrange and bilateral is staggered in the car lane, and the ratio of the distance between the adjacent lamp stand and pole height is generally 3:1-5:1, and the lamp stand cantilever elevation angle is 0 ° to 15 °.For some wider bicycle lane and the street on pavement are arranged, can on a lamp stand, symmetry be installed by two street lamps, be used for shining respectively car lane and bicycle lane.
Common street lighting scene is considered, the inventor further studies discovery, the comparatively reasonably luminous intensity distribution form of LED street lamp is: on C0-180 luminous intensity distribution plane, be on the plane of corresponding road travel direction, its distribution curve flux is the bat aerofoil profile, beam angle is in 135 °-150 ° scope, and largest light intensity is worth corresponding angle in ± 60 ° to ± 65 ° scope, and the ratio of the light intensity value at largest light intensity value and 0 ° of angle line place is in the scope of 1.5:1-3:1; On C90-270 luminous intensity distribution plane, be on the plane of corresponding road width direction, its distribution curve flux is asymmetric, beam angle is in 60 °-100 ° scope, largest light intensity is worth corresponding angle in+10 ° to+45 ° the scope, thereby so that the light intensity value at each the angle place of distribution curve flux positive-angle one side on the C90-270 luminous intensity distribution plane is all greater than the light intensity value at the negative angle place that equates, and then the illuminating ray of LED street lamp guiding more had utilize the direction that is worth, reduce unnecessary light waste, improve the utilance of luminous flux.
Out of doors in the floodlighting scene, the inventor studies discovery, common scene is to arrange one or several high bar in some extensive area, and at several flood lights of high bar installation, thereby by selecting suitable flood light type and rational flood light mounting arrangement being set, illuminate whole extensive area, reach the illuminance of ground value and the uniformity of illuminance that need in this zone, specifically the difference according to the difference of field of illumination scope.
The inventor further studies discovery, and the projection distance that general occasion requires flood light is in 30 meters to 75 meters scope, and the illuminance of ground uniformity in this field of illumination is more than or equal to 0.3; Some special occasions requires the projection distance of flood light to reach 100 meters even farther, and the illuminance of ground uniformity in this field of illumination is more than or equal to 0.5.In addition, meter state of looking for for extensive area, especially main zone of action or working region in this field of illumination, people wish that the distribution of its illuminance of ground is more even better, thus so that the brightness value from the lamp stand lower zone to fringe region is the transition of gradual change.
And the lighting that available technology adopting once light-distribution technique is made, in manufacturing process, be with bimodal lens packages on package support, make itself and luminescence chip, fluorescent glue and package support composition one, become LED to encapsulate single lamp, and the realize target luminous intensity distribution.Wherein, bimodal lens are generally silica-gel lens, and the cutaway view profile in its C0-180 cross section has two highly consistent high points, similar and double-peak shape; The cutaway view profile in its C90-270 cross section is symmetric form.The luminous intensity distribution form of the LED light fixture that this luminous intensity distribution technique obtains is: the C0-180 distribution curve flux is symmetrical bat aerofoil profile, the C90-270 distribution curve flux is symmetrical approximate taper or approximate ellipsoidal, when being applied to street lighting, especially for car lane, be asymmetric illuminating light flux utilance low 5% to 10% than the distribution curve flux on the C90-C270 luminous intensity distribution plane.
And, the LED lighting that available technology adopting once light-distribution technique is made, the luminous intensity distribution form that realizes is: C0-180 luminous intensity distribution plane, light distribution on C90-270 luminous intensity distribution plane and other luminous intensity distribution planes is consistent, namely from distribution curve flux figure, its C0-180 luminous intensity distribution plane, overlap during distribution curve flux on C90-270 luminous intensity distribution plane and other luminous intensity distribution planes, and all be symmetrical, beam angle is in 10 °-60 ° scope, when causing floodlighting that it is applied to outdoor extensive area, some local obvious dark space or speck of occurring in the illumination zone easily appears.As arranging a lamp stand in 75 meters of length, wide 75 meters regional centers, bar is high 30 meters, totally 8 to 12 of lamp stand top layout one circle flood lights, and the lamp installation elevation angle is 55 to 65 degree approximately.When the beam angle of flood light hour, as in 15 ° to 30 ° scope, easily relative dark space occurs at the lamp stand lower zone, and relative speck occurs some of this zone is local; When the beam angle of flood light was larger, such as 60 °, because projection distance is far away not, easily blanking bar appearred in the zone a long way off.
The LED lighting that available technology adopting secondary light-distribution technique is made, mainly be adopt beam angle approximately 120 ° the LED of lambert's type luminous intensity distribution encapsulate single lamp in conjunction with secondary lens, come the realize target luminous intensity distribution.Although, LED lighting compared to the making of once light-distribution technique, the utilance of its luminous flux promotes to some extent, but, when this lighting is applied to street lighting and outdoor floodlighting, LED lighting generally have tens in addition the hundreds of LEDs encapsulate single lamp, cause when concrete the making, need to encapsulate single lamp to every LEDs and all cooperate a secondary lens is installed, this just means that the making of every lighting all needs to install tens even a hundreds of secondary lens.And in installation process, not only secondary lens fixedly needs the production auxiliary materials such as fixing glue, and, the installation of each secondary lens needs artificial careful operation, especially the installation of the secondary lens of unsymmetric structure needs the artificial direction of rotation of carefully grasping every secondary lens, thereby cause adopting the LED lighting of secondary light-distribution technique making, cost is higher, and the production operation complexity is higher.
On the basis based on above-mentioned research, the embodiment of the invention provides a kind of led light source, comprising:
