[specific embodiment]

Referring to Fig. 1～5.A kind of high light LED projector, comprise lamp housing, a plurality of high-brightness LEDs 2, metal substrate 1 and Switching Power Supply, the metal substrate 1 of described pawl type is the aluminium sheet 4 of a block length square, its longer sides extends to horizontal direction one side, and upwards be converted into 4 sections aluminium sheets 5, aluminium sheet 6, aluminium sheet 7, aluminium sheet 8, making the angle between aluminium sheet 4 and the aluminium sheet 5 is 175 °, angle between aluminium sheet 5 and the aluminium sheet 6 is 163 °, angle between aluminium sheet 6 and the aluminium sheet 7 is 171 °, angle between aluminium sheet 7 and the aluminium sheet 8 is 160 °, with aluminium sheet 6, aluminium sheet 7, upwards turn up the both sides of the aluminium sheet 8 outside extension of symmetry respectively, fold the aluminium sheet 9 of symmetry, aluminium sheet 10, aluminium sheet 11, angle between aluminium sheet 9 and the aluminium sheet 8 is 160 °, and the angle between aluminium sheet 10 and the aluminium sheet 7 is 160 °, and the angle between aluminium sheet 11 and the aluminium sheet 6 is 166 °.The high-brightness LED 2 that is with lens 3 is installed on the aluminium sheet 1,6 high-brightness LEDs 2 of one row are installed on the aluminium sheet 4,5 high-brightness LEDs 2 of two rows are installed on the aluminium sheet 5,2 high-brightness LEDs 2 of one row are installed in respectively on aluminium sheet 6, aluminium sheet 7, aluminium sheet 10, the aluminium sheet 11,1 high-brightness LED 2 of one row is installed in respectively on aluminium sheet 8, the aluminium sheet 9, all is with lens 3 on all high-brightness LEDs 2.There is the aluminium sheet 1 of high-brightness LED 2 to be installed in the lamp housing whole erection, and is connected with drive circuit.

The operation principle of this Projecting Lamp is as follows:

Spot light: the size of every light source itself is compared and can be ignored by the distance between the object that shines with it.Spot light is a kind of ideal model. spot light is not mathematical point, but the point on the physical significance, promptly light source itself has certain dimension.

The principle of stacking of light wave: do the time spent simultaneously when the somewhere, space is subjected to two or more light waves, the net amplitude of this place's light vibration, the linear superposition of the complex amplitude vector when should be each light wave to this place independent action.

Two independently light source (two LEDs) be incoherent, just do not return and interference occurs, its mean intensity of closing vibration equals branch oscillation intensity sum.

$\stackrel{\‾}{I}=A_1^2+A_2^2+\mathrm{\Λ}$

Illumination is the physical quantity that characterizes the illuminated degree of area of illumination, concerning spot light:

$E=\frac{\mathrm{Id\&Omega;}}{\mathrm{d\&sigma;}}=\frac{\mathrm{<figure-callout\; id="2"\; label="Ids\; R"\; filenames="Y20072005709100111.png"\; state="\{\{state\}\}">Ids</figure-callout>}}{R^{}}=\frac{I\cos \mathrm{\&alpha;}}{{\mathrm{<figure-callout\; id="2"\; label="R"\; filenames="Y20072005709100111.png"\; state="\{\{state\}\}">R</figure-callout>}}^2}$

That is: E ∝ I

E∝A ²

α is the axis direction of light beam and the angle of area of illumination normal.

Luminous intensity is the physical quantity that characterizes the spatial distribution of the luminous flux that light source sends in the certain orientation scope, and the numerical value of the luminous flux that its available point light source sends in unit solid angle is measured.

$I=\frac{\mathrm{d\&Phi;}}{\mathrm{d\&Omega;}}$

As each LED of hypothesis when being a spot light, all characteristics of its corresponding points light source, and the light that LED sends do not produce interference, diffraction phenomena, and the luminous flux of each LEDs and the transmitance of lens all are identical simultaneously.Like this according to the principle of stacking of light and the illuminance formula of spot light, can obtain the n LEDs illuminated object a bit on the illuminance of stack $E_i=\underset{n=\mathrm{0,1,2,3}...}{\mathrm{\&Sigma;}}{E}_{\mathrm{in}};$ Get any 2 points, make its illuminance identical, reach the light effect of uniform; Calculate for convenient, adopt more satisfactory situation, get 2 special points, that is: the point of half of one group of spot center and two groups of angles, Ei=Ei+,

$E_i=\underset{n=0,\mathrm{1,2,3},...}{\mathrm{\&Sigma;}}{E}_{\mathrm{in}}=\underset{n=\mathrm{1,2,3}\mathrm{\&Lambda;}}{\mathrm{\&Sigma;}}\frac{I_i\cos {\mathrm{\&alpha;}}_i}{R_i^2}$

$E_i+=\underset{n=\mathrm{0,1,2,3}...}{\mathrm{\&Sigma;}}{E_{\mathrm{in}}}^{\&prime;}=\underset{n=\mathrm{1,2,3}\mathrm{\&Lambda;}}{\mathrm{\&Sigma;}}\frac{I_i^{\&prime;}\cos {{\mathrm{\&alpha;}}^{\&prime;}}_i}{{R^{\&prime;}}_i^2}$

$\underset{n=\mathrm{1,2,3}\mathrm{\&Lambda;}}{\mathrm{\&Sigma;}}\frac{I_i\cos {\mathrm{\&alpha;}}_i}{R_i^2}=\underset{n=\mathrm{1,2,3}\mathrm{\&Lambda;}}{\mathrm{\&Sigma;}}\frac{I_i^{\&prime;}{{\cos \mathrm{\&alpha;}}^{\&prime;}}_i}{{R^{\&prime;}}_i^2}$

With the substitution evaluation method value of trying to achieve: have only three unknown numbers in the formula, wherein two unknown numbers are associated: I and γ, in the substitution formula, try to achieve the E value near the time angle.

When lamp being placed in the distance apart from irradiated body 1.5m, illuminated area is 5m*1.5m, and is even at this area glazing.

$=E01+\left(\frac{I^{\&prime;}}{I}\right)E01$

$=(1+\frac{I^{\&prime;}}{I})\frac{I^{\&prime;}{\cos }^3(\mathrm{\&alpha;}+\mathrm{\&beta;}){\mathrm{<figure-callout\; id="2"\; label="cos"\; filenames="Y20072005709100111.png"\; state="\{\{state\}\}">cos</figure-callout>}}^2\mathrm{\&gamma;}}{{1.5}^2}$

∴ ${\mathrm{<figure-callout\; id="2"\; label="cos"\; filenames="Y20072005709100111.png"\; state="\{\{state\}\}">cos</figure-callout>}}^2\mathrm{\&gamma;}=\frac{I^2}{{\mathrm{II}}^{\&prime;}+I^{\&prime;2}}$

Try to achieve with the substitution evaluation method: 10 ° of γ ≈

$d=R\tan 2\mathrm{\&gamma;}$

$=\frac{1.5}{\mathrm{coas}(\mathrm{\&alpha;}+\mathrm{\&beta;})}\tan 2\mathrm{\&gamma;}\&le;0.75$
