Description
Technical field
The present invention relates to the LED lighting technical field, relate in particular to a kind of LED light source, and the LED light source module of a plurality of this LED light source compositions.
Background technology
LED is easy to realize various forms of luminous intensity distributions, can form corresponding LED light source by once light-distribution technique and secondary light-distribution technique.Once light-distribution technique is in the process of making the single lamp of LED encapsulation, with lens packages to package support, make itself and luminescence chip, fluorescent glue and package support form one, thereby consist of the single lamp of LED, that the single lamp type of common LED has is direct insertion, SMD, high-power packaged type etc.; Wherein, the luminescence chip surface is coated with fluorescent glue, and lens are generally silica-gel lens; This technique is equivalent to the disposable target luminous intensity distribution form that realized in the process of making the single lamp of LED encapsulation, and therefore, we claim that usually this technique is once light-distribution technique, and the lens that adopt are called lens No. one time.
Secondary light-distribution technique is another kind of effectively light-configuration mode.A kind of technological means commonly used is to carry out the luminous intensity distribution design by secondary lens, namely installing independently on the basis that makes the single lamp of intact LED, lens carry out the luminous intensity distribution design, the lens that adopt are generally the lens of polymethyl methacrylate (PMMA) material, these lens are independent of outside the single lamp of LED, be called secondary lens, the single lamp of secondary lens and LED forms optical system jointly, obtains target luminous intensity distribution form.
The C-planar system is a kind of measurement commonly used and the coordinate system of description light source or the distribution of light fixture spatial light intensity, and this system can be used in the luminosity measurement of LED light source or light fixture.The spatial light intensity of measuring and describe LED light source or light fixture under the C-planar system distributes, and light distribution is generally described by distribution curve flux; Distribution curve flux is under polar coordinate system or rectangular coordinate system, the corresponding light intensity value of all angles on certain luminous intensity distribution plane that marks, and depict the curve that light intensity value changes with angle; People generally pay close attention to and analyze is distribution curve flux on C0-C180 and C90-C270 these two luminous intensity distribution planes; From distribution curve flux figure, the distribution curve flux on these two planes can overlap, and can be also diverse; The angle that we define the left side of 0 degree angle line in distribution curve flux figure is that the angle on the right side of positive-angle (with "+" expression), 0 degree angle line is negative angle (with "-" expression), distribution curve flux on each plane can be symmetrical expression (with respect to 0 degree angle line left-right symmetry) so, can be also (asymmetric with respect to 0 degree angle line left and right) of asymmetric.Can reading optical beam from the distribution curve flux the value at angle, the beam angle that we define distribution curve flux on certain luminous intensity distribution plane is: the angle value that the angle value that turns over when on beam angle=distribution curve flux, the largest light intensity angle line is rotated counterclockwise angle line to 50% largest light intensity+largest light intensity angle line dextrorotation turns over when going to the angle line of 50% largest light intensity.In addition, in order to express easily, we will be called the C0-C180 cross section with the face of C0-C180 luminous intensity distribution planes overlapping in the LED light source structure, are called the C90-C270 cross section with the face of C90-C270 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.
For street lighting, common car lane is arranged as 2 tracks, track to 8, some street also comprises central partition, greenbelt etc., common lamp stand spread pattern has one-sided arrangement, Bilateral Symmetry arrangement, bilateral to be staggered, the ratio of lamp stand spacing and pole height is generally 3 to 5, and the lamp stand cantilever elevation angle is that 0 degree is to 15 degree; For some, wider bicycle lane and the street on pavement are arranged, can symmetry be installed by two street lamps on a lamp stand, shine respectively car lane direction and bicycle lane direction.In prior art, a kind of luminous intensity distribution form of LED street lamp, or be called symmetric form batswing tab luminous intensity distribution form and be: on the C0-C180 plane (on corresponding road travel direction), its distribution curve flux is the bat aerofoil profile, on the C90-C270 plane (on corresponding road width direction), its distribution curve flux is symmetrical approximate ellipsoidal or approximate taper.A kind of once light-distribution technique for making the road lighting LED light source is in the process of making the single lamp of LED, with bimodal lens or multimodal lens packages to package support, make itself and luminescence chip, fluorescent glue and package support form one, become the single lamp of LED, and the realize target luminous intensity distribution; Lens are generally the lens of silica gel material, and two or more high points are arranged at its front profile top, are similar to the shape at two peaks or a plurality of peaks.A kind of secondary light-distribution technique for making the road lighting LED light source be adopt beam angle approximately the single lamp of LED of lambert's type luminous intensity distributions of 120 degree add bimodal pattern or multimodal secondary lens, come the realize target luminous intensity distribution; Lens are generally the lens of polymethyl methacrylate (PMMA) material, and two or more high points are arranged at its front profile top, are similar to the shape at two peaks or a plurality of peaks.The luminous intensity distribution form that above two kinds of luminous intensity distribution techniques obtain is symmetric form batswing tab luminous intensity distribution, that is: the C0-180 distribution curve flux is that symmetrical bat aerofoil profile, C90-270 distribution curve flux is symmetrical approximate ellipsoidal or approximate taper, but use for street lighting, this luminous intensity distribution form is also unreasonable, especially for car lane, this luminous intensity distribution form is lower than the illuminating light flux utilization rate of asymmetric batswing tab luminous intensity distribution.
