2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Nyob zoo rau txhua tus neeg tsim khoom thiab rau cov zej zog uas tsis muaj kev qhia paub.

Lub sijhawm no Merenel Kev Tshawb Fawb yuav coj los rau koj cov teeb meem tshawb fawb dawb huv thiab ib txoj hauv kev los daws nws nrog lej.

Kuv tau muaj teeb meem no kuv tus kheej thaum kuv tab tom suav cov LED fluxes ntawm RGB LED teeb kuv tau ua (thiab uas kuv yuav qhia yuav tsim li cas). Tom qab tshawb nrhiav hauv online ntau kuv tsis pom cov lus teb, yog li ntawm no kuv tshaj tawm qhov kev daws teeb meem.

Qhov teeb meem

Feem ntau hauv physics peb yuav tsum daws qhov nkhaus uas muaj cov duab ntawm Gaussian faib. Yog! Nws yog lub tswb zoo li tus nkhaus siv los xam qhov tshwm sim thiab tau coj tuaj rau peb los ntawm tus lej lej lej Gauss zoo.

Gauss nkhaus tau siv dav hauv lub neej tiag tiag kev siv lub cev, tshwj xeeb tshaj yog thaum peb yuav tsum cuam tshuam nrog hluav taws xob nthuav tawm los ntawm qhov chaw lossis tau txais los ntawm tus txais, piv txwv li:

- kev tso tawm lub zog ntawm lub teeb liab xov tooj cua (piv txwv li Wi-nkaus);

- lub teeb ci ntsa iab tawm los ntawm LED;

- nyeem ntawv ntawm photodiode.

Hauv cov chaw tsim khoom lag luam peb feem ntau muab tus nqi tiag ntawm thaj chaw ntawm Gaussian, uas yuav yog lub zog hluav taws xob tag nrho lossis cov teeb pom kev zoo nyob hauv qee qhov ntawm cov spectrum (piv txwv li ntawm LED), tab sis nws nyuaj rau suav qhov tseeb hluav taws xob. tso tawm ntawm qhov siab tshaj ntawm txoj kab nkhaus lossis nyuaj dua kom paub cov kab hluav taws xob sib tshooj ntawm ob qhov chaw nyob ze, piv txwv li yog tias peb pom teeb nrog ntau dua ib qho LED (piv txwv li Xiav thiab Ntsuab).

Hauv daim ntawv Qhia Kuv yuav piav qhia koj li cas kwv yees Gaussian nrog txoj kev nkhaus yooj yim dua kom nkag siab: parabola. Kuv yuav teb rau lo lus nug: pes tsawg Gaussian nkhaus nyob hauv Parabola?

SPOILER → Cov lus teb yog:

Gaussian cheeb tsam ib txwm yog 1 chav.

Thaj chaw ntawm cov kab sib chaws sib xws nrog tib lub hauv paus thiab qhov siab yog 2.13 npaug loj dua thaj tsam Gaussian tus txheeb ze (saib daim duab rau daim duab qhia).

Yog li Gaussian yog 46.94% ntawm nws parabola thiab kev sib raug zoo no ib txwm muaj tseeb.

Ob tus lej no cuam tshuam nrog txoj hauv kev no 0.46948 = 1/2.13, qhov no yog qhov kev ua lej sib piv nruj ntawm Gaussian nkhaus thiab nws cov parabola thiab rov ua dua.

Hauv phau ntawv qhia no kuv yuav coj koj mus pom cov kauj ruam no ib kauj ruam zuj zus.

Tsuas yog cov cuab yeej peb yuav xav tau yog Geogebra.org, cov cuab yeej siv lej zoo hauv online rau kev kos duab kab kos.

Daim duab Geogebra kuv tau ua piv rau parabola rau Gaussian tuaj yeem pom ntawm qhov txuas no.

Cov lus qhia no yog ntev vim tias yog hais txog kev ua qauv qhia, tab sis yog tias koj yuav tsum txheeb xyuas qhov teeb meem tib yam uas kuv muaj nrog cov teeb pom kev zoo LED, lossis lwm yam tshwm sim nrog kev sib tshooj Gaussians nkhaus, thov cia li dhia ntawm daim ntawv nthuav qhia uas koj yuav pom txuas ntawm cov kauj ruam 5 ntawm phau ntawv qhia no, uas yuav ua rau koj lub neej yooj yim dua thiab txiav txim siab txhua qhov kev suav rau koj.

Kuv vam tias koj nyiam siv lej vim tias cov ntawv qhia no yog hais txog nws.

Kauj Ruam 1: Nkag Siab Lub Teeb Tawm Los Ntawm Ib Lub Teeb LED

Hauv qhov kev tshuaj xyuas no kuv yuav txiav txim siab ib qho ntawm cov xim LED, raws li koj pom meej los ntawm lawv daim duab spectrum (thawj daim duab) lawv lub zog faib hluav taws xob zoo ib yam li Gaussian uas hloov mus rau hauv x axis ntawm -33 thiab +33nm ntawm qhov nruab nrab (cov tuam ntxhab feem ntau muab qhov tshwj xeeb no). Txawm li cas los xij, txiav txim siab tias kev sawv cev ntawm daim duab no ua rau txhua qhov pom ntawm ib lub zog siv hluav taws xob, tab sis LEDs muaj lub zog sib txawv raws li kev tsim tawm tau zoo npaum li cas thiab hluav taws xob tam sim no (mA) koj pub rau lawv li cas.

Raws li koj tuaj yeem pom qee zaum lub teeb ci ntawm ob lub LED sib tshooj ntawm cov spectrum. Cia peb hais tias kuv xav tau yooj yim los xam thaj tsam sib tshooj ntawm cov nkhaus no, vim tias hauv thaj chaw ntawd yuav muaj lub zog ob npaug thiab kuv xav paub ntau npaum li cas lub zog hauv cov lumen (lm) peb muaj, zoo li tsis yog txoj haujlwm yooj yim peb yuav sim teb hauv phau ntawv qhia no. Qhov teeb meem tshwm sim vim tias thaum kuv tab tom tsim lub teeb sim kuv yeej xav paub ntau npaum li cas Blue thiab Green spectrum tau sib tshooj.

Peb yuav tsom mus rau tsuas yog monochromatic LEDs uas yog cov uas tawm ntawm qhov nqaim ntawm cov spectrum. Hauv daim duab: ROYAL BLUE, BLUE, GREEN, ORANGE-RED, RED. (Lub teeb tiag kuv tsim yog RGB)

PHYSICS QHOV TSEEB

Wb rov qab me ntsis thiab ua qhov piav qhia me ntsis ntawm lub cev thaum xub thawj.

Txhua LED muaj xim, lossis ntau dua kev tshawb fawb peb yuav hais tias muaj lub nthwv dej (λ) uas txiav txim siab nws thiab uas ntsuas hauv nanometers (nm) thiab λ = 1/f, qhov twg f yog qhov nquag oscillation ntawm cov duab.

Yog li dab tsi peb hu RED yog qhov pib (zoo) pawg photons uas oscillate ntawm 630nm, cov photons tsoo qhov teeb meem thiab thaws rau hauv peb lub qhov muag, uas ua raws li tus txais, thiab tom qab ntawd koj lub hlwb ua cov xim ntawm cov khoom li RED; lossis cov photons tuaj yeem ncaj qha rau hauv koj lub qhov muag thiab koj yuav pom cov LED uas ua rau lawv ci hauv xim liab.

Nws tau pom tias qhov peb hu lub teeb yog qhov tseeb tsuas yog ib feem me me ntawm Electromagnetic Spectrum, ntawm 380nm thiab 740nm; yog li lub teeb yog hluav taws xob hluav taws xob. Dab tsi yog qhov xav paub txog qhov feem ntawm cov spectrum yog tias nws yog qhov tseeb ntawm cov spectrum uas yooj yim dua hla dej. Kwv yees dab tsi? Peb cov poj koob yawm txwv puag thaum ub los ntawm Primordial Soup qhov twg yog nyob hauv dej, thiab nws nyob hauv dej qhov uas xub thawj, nyuaj dua, cov neeg muaj sia nyob tau pib tsim qhov muag. Kuv qhia koj kom saib cov vis dis aus los ntawm Kurzgesagt Kuv tau txuas kom nkag siab zoo dua qhov pom kev yog dab tsi.

Txhawm rau suav cov LED tso tawm lub teeb, uas yog qee yam ntawm lub zog hluav taws xob (mW) ntawm qee qhov nthwv dej (nm).

Feem ntau, thaum peb tab tom cuam tshuam nrog pom lub teeb peb tsis tham txog lub zog hluav taws xob (mW) tab sis ntawm cov teeb pom kev zoo (lm), uas yog chav ntsuas ntsuas qhov hnyav ntawm qhov teb rau pom lub teeb ntawm tib neeg lub qhov muag, nws tau tsim los ntawm candela chav ntsuas, thiab nws ntsuas hauv lumen (lm). Hauv qhov kev nthuav qhia no peb yuav txiav txim siab lumens tso tawm daim ntawv LEDs tab sis txhua yam yuav siv rau mW raws nraim tib yam nkaus.

Hauv ib daim ntawv teev npe LED cov chaw tsim khoom yuav muab cov ntaub ntawv no rau koj:

Piv txwv li los ntawm cov ntaub ntawv no txuas nrog koj pom tias yog koj siv zog ob leeg coj nrog 100mA koj muaj qhov ntawd:

XIAV yog nyob ntawm 480nm thiab muaj 11lm ntawm lub teeb ci;

GREEN nyob ntawm 530nm thiab muaj 35lm ntawm lub teeb ci.

Qhov no txhais tau tias Gaussian Nkhaus ntawm Xiav yuav siab dua, nws yuav nce siab ntxiv, yam tsis hloov kho hauv nws qhov dav thiab nws yuav oscillate nyob ib ncig ntawm qhov sib cais los ntawm kab xiav. Hauv daim ntawv no kuv yuav piav qhia yuav ua li cas xam qhov siab ntawm Gaussian uas qhia txog lub zog siab tshaj tawm los ntawm LED, tsis yog tsuas yog lub zog tso tawm hauv qhov feem ntawm cov spectrum, hmoov tsis tus nqi yuav qis dua. Tsis tas li ntawd, kuv yuav sim kwv yees qhov sib tshooj ntawm ob lub LEDs kom nkag siab ntau npaum li cas lub teeb ci tau sib tshooj thaum peb tab tom cuam tshuam nrog LEDs uas yog "cov neeg nyob sib ze" hauv qhov pom kev.

Ntsuas qhov flux ntawm LEDs yog qhov teeb meem nyuaj heev, yog tias koj mob siab xav paub ntau ntxiv Kuv tau xa cov ntawv ntxaws los ntawm Osram uas piav qhia tias yuav ua li cas.

Kauj Ruam 2: Taw qhia rau Parabola

Kuv yuav tsis nkag mus ntau cov ntsiab lus hais txog dab tsi yog parabola vim nws tau kawm ntau yam hauv tsev kawm ntawv.

Qhov sib npaug ntawm parabola tuaj yeem sau rau hauv daim ntawv hauv qab no:

y = ax^2+bx+c

ARCHIMEDES pab peb

Dab tsi kuv xav hais hauv qab yog qhov tseem ceeb geometrical theorem los ntawm Archimedes. Dab tsi theorem hais yog tias thaj tsam ntawm parabola txwv nyob rau hauv ib lub duab plaub yog sib npaug rau 2/3 ntawm thaj tsam duab plaub. Hauv thawj daim duab nrog parabola koj tuaj yeem pom tias thaj chaw xiav yog 2/3 thiab thaj chaw liab yog 1/3 ntawm thaj tsam ntawm lub duab plaub.

Peb tuaj yeem suav qhov parabola thiab nws qhov kev ua zauv paub peb lub ntsiab lus ntawm parabola. Hauv peb qhov xwm txheej peb yuav suav qhov vertex thiab peb paub qhov sib tshuam nrog x axis. Piv txwv li:

XEEB LED Vertex (480,?) Y ntawm lub vertex yog sib npaug rau lub zog luminous tso tawm ntawm qhov siab tshaj plaws nthwv dej. Txhawm rau xam nws peb yuav siv qhov kev sib piv uas muaj nyob nruab nrab ntawm thaj tsam ntawm Gaussian (qhov tseeb tso tawm los ntawm LED) thiab ib qho ntawm parabola thiab peb yuav siv Archimedes theorem kom paub qhov siab ntawm lub duab plaub uas muaj cov parabola ntawd.

x 1 (447,0)

x 2 (513,0)

PARABOLIC QAUV

Saib ntawm daim duab uas kuv tau tshaj tawm koj tuaj yeem pom tus qauv nyuaj los sawv cev nrog parabolas ob peb yam sib txawv LED teeb pom kev zoo, tab sis peb paub tias lawv cov sawv cev tsis zoo ib yam li nws zoo li Gaussian ntau dua.

Txawm li cas los xij, nrog parabolas, siv cov lej lej peb tuaj yeem pom txhua qhov kev sib tshuam taw tes ntawm ob peb parabolas thiab xam thaj tsam sib tshuam.

Hauv qib 5 Kuv tau txuas daim ntawv nthuav qhia uas kuv tau muab txhua tus qauv los laij tag nrho cov parabolas thiab lawv thaj chaw sib tshuam ntawm LEDs monochromatic.

Feem ntau, lub hauv paus ntawm Gaussian ntawm LED yog loj 66nm, yog li yog tias peb paub qhov tseem ceeb nthwv dej thiab peb kwv yees kwv yees hluav taws xob hluav taws xob LED nrog lub parabola peb paub tias tus txheeb ze parabola yuav hla lub x axis hauv λ+33 thiab λ-33.

Qhov no yog tus qauv uas kwv yees ib qho LED tag nrho tso tawm lub teeb nrog parabola. Tab sis peb paub tias yog peb xav kom meej nws tsis yog qhov yog, peb yuav tsum siv Gauss nkhaus, uas coj peb mus rau kauj ruam tom ntej.

Kauj Ruam 3: Taw qhia rau Gaussian Nkhaus

Gaussian nws yog txoj kab nkhaus uas yuav ua suab ntau dua li parabola. Nws tau tsim los ntawm Gauss los txhais lus tsis raug. Qhov tseeb, txoj kab nkhaus no nws muaj txiaj ntsig zoo los saib qhov kev faib tawm ntawm qhov tshwm sim. Raws li peb txav mus rau sab laug lossis sab xis los ntawm lub ntsiab lus peb muaj qee yam tshwm sim tsawg dua thiab raws li koj tuaj yeem pom los ntawm daim duab kawg no nkhaus yog qhov kwv yees zoo ntawm qhov tshwm sim hauv lub neej tiag.

Cov mis Gaussian yog qhov txaus ntshai uas koj pom hauv daim duab thib ob.

Cov khoom Gaussian yog:

- nws yog symmetrical hwm rau lub ntsiab lus;

- x = μ tsis tsuas yog ua ke nrog cov lej zauv tab sis kuj nrog qhov nruab nrab thiab hom;

- nws yog asymptotic ntawm x axis ntawm txhua sab;

- nws txo qis rau xμ;

- nws muaj ob lub ntsiab lus cuam tshuam hauv x = μ-σ;

- cheeb tsam hauv qab nkhaus yog 1 chav (yog qhov tshwm sim uas ib qho x yuav txheeb xyuas tau)

σ yog tus qauv sib txawv, qhov loj dua tus lej dav dua Gaussian puag yog (thawj daim duab). Yog tias tus nqi nyob hauv 3σ feem peb yuav paub tias nws txav mus deb ntawm qhov nruab nrab thiab muaj qhov tshwm sim tsawg dua rau nws tshwm sim.

Hauv peb qhov xwm txheej, nrog LEDs, peb paub thaj tsam ntawm Gaussian uas yog lub teeb ci ci tau muab tso rau hauv cov chaw tsim khoom lag luam ntawm qhov muab qhov ntev nthwv dej (uas yog lub ntsiab lus).

Kauj Ruam 4: Qhia nrog Geogebra

Hauv ntu no kuv yuav qhia koj li cas siv Geogebra los ua pov thawj tias parabola yog 2.19 npaug nws Gaussian.

Ua ntej koj yuav tsum tsim ob peb qhov sib txawv, nyem rau ntawm kab hais kom ua slider:

Tus txheej txheem sib txawv σ = 0.1 (tus qauv sib txawv piav qhia dav npaum li cas Gauss nkhaus yog, Kuv muab tus nqi me me vim tias kuv xav ua kom nws nqaim los sim ua ib qho LED spectral zog faib)

Qhov nruab nrab yog 0 yog li Gaussian tau tsim rau ntawm y axis, qhov twg nws yooj yim dua los ua haujlwm.

Nyem rau ntawm qhov ua haujlwm yoj me me kom qhib ntu ua haujlwm; muaj los ntawm txhaj rau fx koj tuaj yeem ntxig rau Gaussian cov mis thiab koj yuav pom popping li ntawm qhov screen zoo siab Gaussian Nkhaus.

Cov duab koj yuav pom qhov nkhaus sib tshuam ntawm x axis, hauv kuv qhov xwm txheej hauv X1 (-0.4; 0) thiab X2 (+0.4; 0) thiab qhov twg vertex nyob hauv V (0; 4).

Nrog peb lub ntsiab lus no koj muaj cov ntaub ntawv txaus los nrhiav qhov sib npaug ntawm parabola. Yog tias koj tsis xav suav los ntawm txhais tes xav siv lub vev xaib no lossis daim ntawv nthuav tawm hauv cov kauj ruam tom ntej.

Siv lub luag haujlwm hais kom ua (fx) txhawm rau ua kom muaj nuj nqi parabola koj nyuam qhuav pom:

y = -25x^2 +4

Tam sim no peb yuav tsum nkag siab pes tsawg Gaussians nyob hauv parabola.

Koj yuav tsum tau siv cov lus txib ua haujlwm thiab txhawm rau txhawm rau hais kom ua Integral (lossis Integrale hauv kuv kis, raws li kuv tau siv Italis version). Lub ntsiab lus tseem ceeb yog kev ua lej uas tso cai rau peb xam thaj tsam ntawm txoj haujlwm uas tau txhais los ntawm x qhov tseem ceeb. Yog tias koj tsis nco qab qhov tseeb qhov tseem ceeb yog dab tsi, nyeem ntawm no.

a = Integral (f, -0.4, +0.4)

Cov qauv Geogebra no yuav daws qhov kev piav qhia nruab nrab ntawm -0.4 thiab +0.4 ntawm txoj haujlwm f, Gaussian. Raws li peb tab tom cuam tshuam nrog Gaussian nws thaj tsam yog 1.

Ua tib yam rau parabola thiab koj yuav pom cov lej khawv koob 2.13. Uas yog tus lej tseem ceeb los ua txhua qhov kev hloov pauv hloov pauv nrog LEDs.

Kauj Ruam 5: Piv Txwv Lub Neej Zoo Nrog LEDs: Xam Qhov Flux Peak thiab Fluxes Cuam Tshuam

LUMINOUS FLUX ntawm lub ncov

Txhawm rau suav qhov siab tiag ntawm qhov nkhaus Gaussian nkhaus ntawm LED flux faib, tam sim no peb tau pom qhov hloov pauv hloov pauv 2.19, yog qhov yooj yim heev.

piv txwv:

XEEB LED muaj 11lm ntawm qhov ci ci

- peb hloov pauv qhov no los ntawm Gaussian mus rau parabolic 11 x 2.19 = 24.09

- peb siv Archimedes Theorem los xam thaj tsam plaub fab txheeb ze uas muaj cov parabola 24.09 x 3/2 = 36.14

- peb pom qhov siab ntawm daim duab plaub sib faib rau lub hauv paus ntawm Gaussian rau BLUE LED, muab hauv cov ntawv lossis pom ntawm daim ntawv teev npe, feem ntau nyob ib puag ncig 66nm, thiab qhov ntawd yog peb lub zog ntawm qhov siab tshaj ntawm 480nm: 36.14 / 66 = 0.55

HLOOV LUMINOUS FLUX AREAS

Txhawm rau xam ob qhov hluav taws xob sib tshooj kuv yuav piav qhia nrog ib qho piv txwv nrog ob qho LEDs hauv qab no:

XIAV yog 480nm thiab muaj 11lm ntawm qhov ci ntsa iab GREEN yog ntawm 530nm thiab muaj 35lm ntawm qhov ci ci ci

Peb paub thiab peb pom los ntawm daim duab qhia tias ob qho tib si Gaussian nkhaus sib tshuam hauv -33nm thiab +33nm, yog li peb paub tias:

BLUE sib tshuam x axis hauv 447nm thiab 531nm

- GREEN sib tshuam x axis hauv 497nm thiab 563nm

Peb pom meej tias ob txoj kab nkhaus sib tshuam ua ib qho kawg ntawm thawj qhov yog tom qab pib ntawm lwm qhov (531nm> 497nm) yog li lub teeb ntawm ob lub LEDs sib tshooj hauv qee cov ntsiab lus.

Peb xub yuav tsum xam cov kab zauv parabola rau ob qho tib si. Daim ntawv nthuav qhia txuas nrog nyob ntawd los pab koj nrog kev suav, thiab tau kos cov qauv los daws cov kab ke ntawm kab zauv los txiav txim siab ob kab lus parabolas paub x axis sib tshuam cov ntsiab lus thiab lub vertex:

XUB parabola: y = -0.0004889636025x^2 + 0.4694050584x -112.1247327

GREEN parabola: y = -0.001555793281x^2 + 1.680256743x - 451.9750618

hauv ob qho xwm txheej a> 0 thiab, yog li parabola tau ua kom raug taw tes-up-down.

Txhawm rau ua pov thawj tias daim ntawv parabolas no yog lawm tsuas yog sau hauv a, b, c hauv lub tshuab xam zauv ntawm qhov chaw ntawm lub vev xaib no lub tshuab xam zauv parabola.

Ntawm daim ntawv nthuav qhia tag nrho cov laij lej twb tau ua los nrhiav cov ntsiab lus sib tshuam ntawm cov parabolas thiab los laij cov ntsiab lus tseem ceeb kom tau txais thaj chaw sib tshuam ntawm cov parabolas.

Kuv peb rooj plaub qhov chaw sib tshuam ntawm xiav thiab ntsuab LED spectra yog 0.4247.

Thaum peb muaj cov kab sib tshuam sib tshuam peb tuaj yeem muab thaj tsam sib koom ua ke tshiab no rau Gaussian sib npaug 0.4694 thiab pom qhov ze ze ntawm ntau npaum li cas lub zog ntawm cov LEDs tau tso ua ke nyob rau hauv tag nrho hauv ntu ntawm cov spectrum. Txhawm rau nrhiav ib qho LED flux tso tawm hauv ntu ntawd tsuas yog faib los ntawm 2.
