One of important technical measures: diamond to be made obtains the most beautiful maximum fiery coloured silk will be to boring
Stone light total reflection provides necessary path.This just requires not only must in the main crown of diamond and main booth face
Must be the most symmetrical, and require that the upper and lower mainboard of diamond must be corresponding.Thus the main crown of diamond
Must be all equal even number face with main booth face.
The two of important technical measures: it is color that diamond to be made obtains the most beautiful maximum fire, more important
Be design under conditions permit main crown and main booth face area maximize.
Prove through experiment: can diamond obtain the most beautiful maximum fiery coloured silk is to be all-trans by diamond light
Firing association's efficiency (W) determines；And gross efficiency (W) and main crown light total reflection daylight rate
And main booth face light total reflection efficient (N) direct proportionality (M).Wherein, main crown
Light total reflection light rate (M) is bizet main crown total reflection light effective area and the total face of bizet
Long-pending ratio: main booth face light total reflection efficient (N) is main booth face, booth portion light total reflection significant surface
The long-pending ratio with main crown total reflection light effective area.
One of important invention: from abovementioned technology, draw the diamond of first important invention
Light total reflection gross efficiency computing formula is: W=MN.
From above-mentioned formula, it is color that diamond to be made obtains the most beautiful maximum fire, it is necessary to greatest extent
Ground improves diamond light total reflection gross efficiency W, and this will design the area of main crown to greatest extent
Expand M value and design the area in main booth face to greatest extent and could realize to expand N value.One
As design the 90% of main crown and main booth face Ge Zhan our department area respectively and be preferred.
This computing formula of W=MN is applicable to: each main booth face of diamond can reflect one
The color Strength co-mputation of fire that fire is color.
Such as: " bright type diamond " light total reflection gross efficiency is calculated as follows:
Main crown light total reflection daylight rate is: the original entire area of bizet is 100%, has master in fact
Crown can be totally reflected daylighting area and calculate is 45%, i.e. light total reflection daylight rate is:
M=45% ÷ 100%=45%；
Main booth face light total reflection is efficient is: the original entire area in booth portion is 100%, has tiny in fact
To be totally reflected effective area and calculate be 15% in flechette-type main booth face, main crown total reflection light has
Effect area is 45%；I.e. light total reflection is efficient is: N=15% ÷ 45%=33%.
So, this diamond light total reflection gross efficiency is: W=MN=45% × 33%=15%.
This diamond light total reflection gross efficiency i.e. only has 15%；Thus each main booth face can only reflect one
The least individual fire is color.This is owing to the M value of this diamond and N value are the least and make light total reflection
Gross efficiency W value is the lowest caused.(referring to accompanying drawing 4)；
The three of important technical measures: it is color, especially that diamond to be made obtains the most beautiful maximum fire
It is important to set angle ingeniously to main crown and main booth face.Experiment proves: when designing main crown angle
Degree is 37.5～38.5 degree and time main booth face angle is 40.5～41.5 degree, and total reflection light is not only
Can enter from main crown and reflect again fire coloured silk from main booth face；Can also enter again from main booth from table top
It is color that face reflects fire, this just can make each main booth face of diamond can reflect two same powerful
Beautiful fire is color！
The two of important invention: from abovementioned technology, draw the diamond of second important invention
Light total reflection gross efficiency computing formula is: W=2MN.
This computing formula is applicable to: each main booth face of diamond can reflect two same powerful
The color color Strength co-mputation of fire of beautiful fire.This computing formula discloses diamond can burst out maximum
The objective law that the most U.S. fire is color.
Referring to the drawings 5, the most such as: " colorful and bright brill " stone is owing to calculating public affairs according to above-mentioned second
The requirement of formula, the area designing main crown and main booth face maximizes, and has special angle,
It is thus able to reflect the most beautiful maximum fire color:
Main crown light total reflection light rate is: the design bizet gross area is 100%；Main crown
The effective area of light is the 90% of our department, i.e. M=90% ÷ 100%=90%；
Main booth face light total reflection is efficient is: the design booth portion gross area is 100%；Main crown
Light effective area is 90%；The total reflection effective area in main booth face is the 90% of our department,
That is: N=90% ÷ 90%=100%.
So, this diamond light total reflection gross efficiency is:
W=2MN=90% × 100% × 2=90% × 2.This diamond light total reflection i.e. is always imitated
Rate is two 90%；Thus each main booth face can burst out two same powerful beautiful fire
Color！(referring to accompanying drawing 5)
The color intensity contrast of fire of " colorful and bright diamond " and " bright type diamond ":
" colorful and bright diamond ": " bright type diamond "=90% × 2:15%=12:1
Prove through above-mentioned contrast: the color intensity of fire of colorful and bright diamond is " bright type diamond "
The twelvefold of the color intensity of fire！
People can be seen clearly that for existing actual sample and " demonstrator ": the technology of the present invention energy
Make novel diamond burst out the most beautiful maximum fire color, colourless and light diamond can not only be made to reflect
Go out seven color in riotous profusion brilliant radiance！The beautiful light of the fancy color diamond color of big releasing own can also be made
Awns so that it is aesthetic values obtain greatly distillation！
The foregoing is only the selection examples of implementation of the present invention, the change of any style or
Material transitions, within all belonging to the protection domain of patent of the present invention.
