Abstract
The invention discloses LED lamp bead location modes built in a kind of special-shaped illuminator towards uniform illumination target, it is based primarily upon mass center capacity limit Power figure, applied to the distribution problem for solving the LED lamp bead on special-shaped illuminator bottom plate, by generating mass center capacity limit Power figure in irregular figure, and the LED lamp bead on the site location of the mass center capacity limit Power figure on reasonable layout abnormity illuminator bottom plate, achieve the purpose that the uniform-illumination of special-shaped illuminator bottom plate, and prevents the problem of part LED lamp bead is placed in special-shaped illuminator bottom edge.
Description
Technical field
It is specifically a kind of towards the different of uniform illumination target the present invention relates to computer geometry and field of Computer Graphics
LED lamp bead location mode built in shape illuminator.
Background technique
In regular LED illuminator, the distance between LED lamp bead on illuminator bottom plate need to be only set, according to setting
The range distribution LED lamp bead set can achieve the effect that uniformly light-emitting.And for the LED on LED abnormity illuminator bottom plate
How lamp bead should be distributed, and so that the illumination effect of LED abnormity illuminator is reached best problem urgently to be resolved always.
The scheme used now is to copy the LED lamp bead distribution mode of general regular LED illuminator, passes through artificial side
Formula is in rectangular base plate after distribution LED lamp pearl, then cuts to rectangle plane bottom plate, obtain as defined in special-shaped illuminator bottom
Plate is manually adjusted further according to position of the situation to LED lamp bead.This mode easily leads to special-shaped illuminator bottom plate uneven illumination
Even, bandwagon effect is bad, while part LED lamp bead is placed in special-shaped illuminator bottom edge, wastes small bulbs.And due to adopting
Manually process is tedious for mode, time-consuming and laborious, and when batch production expends huge manpower and material resources.
Summary of the invention
The object of the present invention is to provide LED lamp bead distribution sides built in a kind of special-shaped illuminator towards uniform illumination target
Method, this method are schemed based on mass center capacity limit Power, and distribution problem of the LED lamp bead on special-shaped illuminator bottom plate is solved
Method keeps distribution of the LED lamp bead on special-shaped illuminator bottom plate more reasonable, so that special-shaped illuminator is reached target light emission luminance, reach
To the purpose of the uniform-illumination of LED abnormity illuminator bottom plate, more preferably bandwagon effect is made it have.
The present invention is to solve current problem, and used technical solution is as follows:
Towards LED lamp bead location mode built in the special-shaped illuminator of uniform illumination target, which is characterized in that according to the following steps
It carries out:
Step 1. sets area as SpSpecial-shaped illuminator baseplate zone be Problem AreasIt (defines i)
Step 2. sets single LED lamp bead on special-shaped illuminator bottom plate as website xi, then have set of sites X={ xi, i=1,2,
3 ... n } indicate LED lamp bead distributing position, according to effective illuminating area S of the single LED lamp bead in the case where meeting given illuminationL, by
Step 1 can obtain reference value
Step 3. sets effective area S of the single LED lamp bead on special-shaped illuminator bottom plate in the case where meeting given illuminationLTo hold
It measures ci (ci > 0), then has given capacity setAnd
For step 4. in step 1 in described problem domain, generation meets set of sites in step 2, capacity set requirement in step 3
Mass center capacity limit Power figure；
Step 5. marks the site location of step 4 mass center capacity limit Power figure；
The site location that step 6. is generated according to step 5 places LED lamp bead on special-shaped illuminator bottom plate.
Compared with the prior technical scheme, advantage of the invention is embodied in:
Schemed the present invention provides a kind of using mass center capacity limit Power, solves LED lamp bead on special-shaped illuminator bottom plate
The scheme of distribution problem, to achieve the purpose that the uniform-illumination of special-shaped illuminator bottom plate；Meanwhile the program solves existing scheme
The problem of existing part LED lamp bead is easily placed in special-shaped illuminator bottom edge reduces the use of LED lamp bead to the greatest extent, section
About cost, and the program can overall process using machine operate, be suitable for batch production.
Detailed description of the invention
Fig. 1 is the flow chart of the method for the present invention.
Fig. 2 is the distribution scheme of the LED lamp bead on general special-shaped illuminator bottom plate.
Fig. 3 is modeled as Problem Areas to special-shaped illuminator bottom plate
Fig. 4 is to Problem AreasMass center capacity limit Power figure is generated, and marks site location.
Specific embodiment
The present invention is that the LED lamp bead distribution problem on special-shaped illuminator bottom plate is modeled as mass center and is held by establishing model
Amount limitation Power map generalization problem, achievees the purpose that special-shaped illuminator bottom plate uniform-illumination.
Power figure is the cum rights extension of Voronoi diagram, and Voronoi diagram is a kind of splitting scheme in space, is made each
The distance of point to the region website in Voronoi area is minimum.And Power figure then assigns weight to each website, it is again fixed
Distance conception in adopted Voronoi diagram.On this basis Power is schemed to apply capacity-constrained and mass center constrains, available base
Scheme in the capacity limit Power of mass center.
As refering to what is shown in Fig. 1, LED lamp bead location mode built in towards the special-shaped illuminator of uniform illumination target, is specifically pressed
Following steps carry out:
Area is S by step a.pSpecial-shaped illuminator baseplate zone be set as Problem Areas
Single LED lamp bead on special-shaped illuminator bottom plate is set as website x by step b.i, then have set of sites X={ xi, i=1,
2,3 ... n } indicate LED lamp bead distributing position, according to effective illuminating area S of single lamp beadL, by illuminator special-shaped in step a
The area of bottom plate is SpReference value can be obtained
Effective area S of the step c. by single LED lamp bead on special-shaped illuminator bottom plate, in the case where meeting given illuminationL
For capacity ci (ci > 0), then there is given capacity set
For step d. in the Problem Areas described in step a, generation meets set of sites in step b, capacity set requirement in step c
Mass center capacity limit Power figure.
Step e. marks the site location of mass center capacity limit Power figure generated in step d.
Step f. is by the site location in step e, the distribution LED lamp pearl on special-shaped illuminator bottom plate, reaches abnormity and shines
The purpose of the uniform-illumination of body bottom plate.
