Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
What first need to indicate is, hereinafter [LED] makes a general reference the not LED chip of encapsulation, or packaged LED lamp is as surface-adhered type (SMT, surface mounted technology) LED lamp or plug-in type (PTH, pin through hole) LED lamp.
Hold above-mentioned, the prerequisite of the mixed lamp method of LED of the embodiment of the present invention is the monochromatic LED that a plurality of steppings need to be provided, specifically can be: the monochromatic LED to same batch or different batches carries out stepping, for example according to the characteristics of luminescence of monochromatic LED for example the difference of wavelength and brightness different gears are set, for example wavelength arranges X shelves, brightness arranges Y shelves, is finally divided into X * Y monochromatic LED gear.Take blue-ray LED as example, suppose that its wavelength coverage is for example 450nm～470nm (nanometer), brightness range is for example 1000mcd～1200mcd (milli candela); Take every 2nm as one grade, and wavelength basis can be divided into 10 grades; Take 20mcd as one grade, according to brightness, can be divided into 10 grades, finally blue-ray LED can be divided into 10 * 10=100 gear.Stepping mode for other colors LED is similar, at this, gives an example no longer one by one.
Next, in connection with Fig. 1, the mixed lamp method of the LED of the embodiment of the present invention is elaborated.For convenience of description, below each embodiment only with the mixed lamp figure generative process of the single color LED of LED display module as an example, the mixed lamp figure generative process of other colors LED can be carried out with reference to this mixed lamp figure generating mode.
[the first embodiment]
The first step, mixed lamp figure unit are determined.
(1). according to the specification of LED display module (M * N) and the gear number (W) of a plurality of monochromatic LEDs, determine the mixed lamp figure quantity that LED display module is corresponding, specifically can be: the quotient after the gear number of the specification of LED display module (being also pixel quantity) and a plurality of monochromatic LEDs is divided by rounds operation, and finds immediate with it 2 according to the value of rounding
n(also 2 n power) value; The specification of supposing LED display module is 32 * 32, and the gear number of a plurality of monochromatic LEDs is 100 grades, therefore (M*N)/W=(32*32)/100=10.24, and the value of rounding of quotient is 10, and with 10 immediate 2
nvalue is 8 or 16; Therefore mixed lamp figure element number corresponding to LED display module that can set 32 * 32 specifications is 8 or 16.It should be noted that herein, be not limited to quotient to round operation, can be also to adopt rounding-off method.
(2). according to the specification of LED display module and the mixed lamp figure element number of determining, determine monochromatic LED quantity in single mixed lamp figure unit:
(M*N)/(2
n)=(32*32)/8=128 or (32*32)/16=64, in the single mixed lamp figure unit of determining like this, monochromatic LED quantity can be 128 or 64, as for the shape of single mixed lamp figure unit, preferably identical with LED display module, also be square, can certainly be different.
Second step, redefine the stepping situation of monochromatic LED.
(1) the mixed lamp figure element number of determining is made as to the monochromatic LED gear number after stepping again: for example monochromatic LED again the gear number of stepping be 128 or 64.
(2) by monochromatic LED total quantity (being assumed to be 1,000,000) divided by the gear number after stepping again, to obtain again the average of the included monochromatic LED of each gear after stepping:
If get 128 as gear number, the average numerical digit of monochromatic LED of these 128 gears after stepping again: 1,000,0,00/,128 7812 of ≈;
If get 64 as gear number, the average numerical digit of monochromatic LED of these 64 gears after stepping: 1,000,000/64=15625 again;
(3) according to monochromatic LED average and gear number, carry out stepping again, and make the monochromatic LED of each gear basic identical:
If get 128 for gear number, in existing 100 gears, unnecessary monochromatic LED outside in each gear 7812 is put into the gear of adjacent and 7812 monochromatic LEDs of number less than of the characteristics of luminescence (wavelength and brightness), or put into 28 gears that again separate; Unnecessary monochromatic LED in existing same gear is put into new same gear herein, as far as possible.
If get 64 as gear number, from existing 100 gears, find out 36 minimum gears of monochromatic LED number, monochromatic LED in these 36 gears is put into the gear of adjacent and 15625 monochromatic LEDs of number less than of the characteristics of luminescence (wavelength and brightness), the existing gear that is greater than 15625 for monochromatic LED, need to put into unnecessary monochromatic LED the gear of adjacent and 15625 monochromatic LEDs of number less than of the characteristics of luminescence; Unnecessary monochromatic LED in existing same gear is put into new same gear herein, as far as possible.
The 3rd step, utilize each mixed lamp figure unit that stochastic ranking algorithm generates LED display module to obtain mixed lamp figure.
(1). for each gear of monochromatic LED is numbered:
If the gear number of the monochromatic LED after redefining is 128, successively 128 gears are numbered respectively to 1,2 ..., 128.
(2). utilize stochastic ranking algorithm, using single mixed lamp figure unit specification as input number, the random mixed lamp figure unit that generates:
If single mixed lamp figure unit specification is 16 * 8, matrix diagram that comprises 128 grid of single mixed lamp figure unit formation, and each grid can have a numbering, and the 128 grid matrix diagram that form are lower attached matrix for example.
This stochastic ranking algorithm is a kind of aligning method of sampling without peplacement, is similar at random and shuffles, and raffle etc., algorithm is a variety of, for example following algorithm.Following source program is 1,2 ..., 128 numerals, random alignment, produces not repeating random number.
Its specific code is as follows:
on?generateList
global?gEmpty,randomList
set?randomList＝[]
repeat?with?x＝1to128
addAt(randomList,random(x),x)
end?repeat
end
| 2 | 8 | 16 | 11 | 21 | 23 | 37 | 58 |
| 52 | 75 | 86 | 109 | 5 | 13 | 94 | 81 |
| … | … | … | … | … | … | … | … |
| … | … | … | … | … | … | … | … |
| … | … | … | … | … | … | … | … |
| 19 | 98 | 78 | 63 | 52 | 108 | 7 | 14 |
| 128 | 17 | 3 | 55 | 82 | 34 | 48 | 80 |
(3). a plurality of mixed lamp figure unit combination of a LED display module is formed to mixed lamp figure:
Utilize the random a plurality of mixed lamp figure unit producing of stochastic ranking algorithm to form the mixed lamp figure of this LED display module, the single mixed lamp figure unit being for example comprised of 8 mixed lamp figure unit is that the mixed lamp figure of 128 cells is the mixed lamp figure cell array of 2 * 4.Each the mixed lamp figure unit herein preferably mixing in lamp figure does not allow simply to copy stickup, must be again to produce at random.
At this, it should be noted that, utilizing stochastic ranking algorithm to generate in the process of mixed lamp figure unit, the expression that each gear of monochromatic LED is numbered is not limited to aforesaid numeral, and it also can adopt other modes to express different gears, different colours for example, different letter etc.
In the present embodiment, in mixed lamp figure unit determining step, also can adopt: according to the business of the specification of LED display module (MxN) and the gear number (W) of monochromatic LED and the product of mixed lamp error tolerance value (V), round, by with to round result the most approaching and be greater than this and round 2 of result
nvalue is as mixed lamp figure element number, and by the specification of described LED display module divided by 2
nthe business of value is as monochromatic LED quantity in single mixed lamp figure unit.For example: (M*N)/(W*V)=(32*32)/(100*5)=2.048 are also that business's the result that rounds is 2, and with 2 the most approaching and be greater than 22
nvalue is 4; Therefore the mixed lamp figure element number of LED display module can be defined as to 4; And monochromatic LED quantity is (M*N)/(2 accordingly in single mixed lamp figure unit
n)=(32*32)/4=256.
[the second embodiment]
Suppose to want 1000 of the LED display modules of manufacturing specification 32 * 32, current have 5 grades of monochromes (for example blue) LED, is respectively:
| LED gear | LED chip quantity in single gear |
| First grade | 250,000 |
| Second gear | 250,000 |
| Third gear | 200,000 |
| Fourth speed | 200,000 |
| The 5th grade | 150,000 |
At this, it is worth mentioning that, the LED display module quantity that wish is made can be determined by the monochromatic LED quantity sum of each gear and the specification of LED display module, for example: (250,000+250,000+200,00+200,000+150,000)/(32*32) ≈ 1025, therefore can set the LED display module quantity that wish makes is 1000, it is less than quotient (1025).
The first step, mixed lamp figure unit are determined.
(a) 32 * 32 specification LED display modules are divided into 2
nindividual mixed lamp figure unit.
Herein, the value of n can be with reference to the gear number of current monochromatic LED.The mode of reference can be: according to the specification characteristic (as P10, P5 etc.) of the LED display module of actual production and the determined mixed lamp error tolerance value of precision characteristic (the maximum tolerance number that same shelves monochromatic LED concentrates in together), determine, for example the mixed lamp error tolerance value of actual production is 5, by the maximum gear of the monochromatic LED quantity monochromatic LED quantity (250 of first grade for example, 000) the LED display module quantity 1000 made from wish and the product of mixed lamp error tolerance value 5 are divided by, and find this quotient the most approaching and be greater than 2 of this quotient
nvalue, i.e. 250,000/ (1000*5)=50, and with 50 the most approaching and be greater than 50 2
nvalue is 64, the mixed lamp figure element number of LED display module can be defined as to 64; In single mixed lamp figure unit, monochromatic LED quantity is (32*32)/64=16.Total principle is: in single mixed lamp figure unit, the number of same shelves monochromatic LED must not surpass mixed lamp error tolerance value.
Second step, redefine the stepping situation of monochromatic LED.
(1). determine the quantity of each gear monochromatic LED in each mixed lamp figure unit:
Quotient after being divided by according to the quantity of each gear monochromatic LED and the LED display module quantity of wish making and the product of mixed lamp figure element number, determines the quantity of each gear monochromatic LED in single mixed lamp figure unit.
In single mixed lamp figure unit, need the number of each gear monochromatic LED of setting to be:
First grade: 250,000/ (1000*64)=3.9 ≈ 4
Second gear: 250,000/ (1000*64)=3.9 ≈ 4
Third gear: 200,000/ (1000*64)=3.125 ≈ 3
Fourth speed: 200,000/ (1000*64)=3.125 ≈ 3
The 5th grade: 150,000/ (1000*64)=2.34375 ≈ 2
It should be noted that herein, for the number of each gear monochromatic LED, be not limited to adopt rounding-off method, also can round operation to quotient.
(2). determine in single mixed lamp figure unit, whether there is monochromatic LED ignore:
Particularly, because monochromatic LED quantity in single mixed lamp figure unit is: (32*32)/64=16, and five gears monochromatic LED number sum in each mixed lamp figure unit: 4+4+3+3+2=16, it represents not exist monochromatic LED ignore.
If there is ignore, need remaining monochromatic LED to fill up.Suppose that the monochromatic LED in fourth speed changes into 150,000, the monochromatic LED in first grade is changed into 280,000, in each mixed lamp figure unit, needs the number of each grade of monochromatic LED arranging to be:
First grade: 280,000/ (1000*64)=4.375 ≈ 4
Second gear: 250,000/ (1000*64)=3.9 ≈ 4
Third gear: 200,000/ (1000*64)=3.125 ≈ 3
Fourth speed: 150,000/ (1000*64)=2.34375 ≈ 2
The 5th grade: 150,000/ (1000*64)=2.34375 ≈ 2
Now five gears number sum in single mixed lamp figure unit is: 4+4+3+2+2=15, indicates 1 ignore; Therefore each grade of remaining monochromatic LED need to be filled up to this ignore, as individual in (150,000-1,000*64*2=22,000) in fourth speed, in the 5th grade 22,000, in first grade 24,000 and third gear 8,000.Then the LED display module quantity of making divided by wish by each grade of remaining monochromatic LED quantity and the product of mixed lamp figure element number, that is:
First grade: 24000/ (1000*64)=0.375
Third gear: 8000/ (1000*64)=0.125
Fourth speed: 22000/ (1000*64)=0.34375
The 5th grade: 22000/ (1000*64)=0.34375
Now need to from a plurality of quotients, select a plurality of sums to be about 1 gear and form the hybrid range of filling up ignore, as 0.375+0.34375+0.34375=1.0625, remaining monochromatic LED in first, the 4th and the 5th grade is formed to the hybrid range of filling up ignore.Actual practice can be that these are chosen and in gear, remain monochromatic LED and put together and again become a gear, also can proportionally in mixed lamp figure, fill up ignore (for example, at plug-in unit machine transplanting of rice lamp, when chip mounter subsides lamp or adsorption plant absorption LED chip carry out COB encapsulation, according to first grade: fourth speed: the ratio of the 5th grade=4:3:3 is taken monochromatic LED).In addition,, because second gear is to substitute 3.9 with 4, first grade in use there will be and lacks lamp phenomenon, also needs to go to supplement with unnecessary monochromatic LED (as the monochromatic LED of third gear).
In addition, if when the number sum of each grade of monochromatic LED has surpassed in single mixed lamp figure unit monochromatic LED number, need to the number of each gear monochromatic LED be redefined, now as long as locally adjust indivedual gears.Suppose that the monochromatic LED in third gear changes into 230,000, five gears monochromatic LED number in single mixed lamp figure unit is respectively:
First grade: 25000/ (1000*64)=3.9 ≈ 4
Second gear: 25000/ (1000*64)=3.9 ≈ 4
Third gear: 23000/ (1000*64)=3.59375 ≈ 4
Fourth speed: 200000/ (1000*64)=3.125 ≈ 3
The 5th grade: 150000/ (1000*64)=2.34375 ≈ 2
Now, five gears number sum in single mixed lamp figure unit is: 4+4+4+3+2=17, have more 1 lamp point, and therefore the number of the monochromatic LED of third gear can be adjusted into 3.
The 3rd step, utilize mixed lamp figure unit that stochastic ranking algorithm generates LED display module to obtain mixed lamp figure.Concrete mode can, with reference to the relevant narration of [the first embodiment], not repeat them here.
