Qhov Laser Diode yuav zoo tshaj rau kev kho lub teeb liab?

Xaiv txoj cailaser dioderau kev kho lub teeb liab (RLT) yuav tsum nkag siab qhov sib npaug ntawm kev kho mob, kev nyab xeeb, kev ua tau zoo, thiab tus nqi. Rau feem ntau tus kheej / ntawm-cov khoom siv hauv tsev RLT, siab-powered 660nm (dub liab) thiab 850nm (ze-}infrared) laser diodes yog cov qauv kub ua ke.

Cov ntsiab lus tseem ceeb rau RLT Laser Diodes:

Lub wavelength:Qhov no yog qhov tseem ceeb tshaj plaws. Nws txiav txim siab qhov tob ntawm kev nkag mus thiab cov txheej txheem cellular tshwj xeeb qhib.

630-660nm (pom liab):Zoo heev rau cov teeb meem ntawm daim tawv nqaij, kho qhov txhab, thiab tiv thaiv - cov teebmeem inflammatory. Absorbed los ntawm mitochondria, stimulating ATP (zog) ntau lawm.

810-850nm (Nyob ze-Infrared - NIR):Nkag mus tob dua (rau hauv cov leeg, pob qij txha, thiab pob txha). Qhov zoo tshaj plaws rau qhov mob sib sib zog nqus, cov leeg nqaij, thiab cov teebmeem hauv lub cev.

Dual Wavelength (piv txwv li, 660nm + 850nm):Feem ntau niaj hnub, siab - cov khoom siv kawg siv qhov kev sib xyaw ua ke no txhawm rau tsom rau ob qho tib si ntawm daim tawv nqaij thiab qhov tob tob ib txhij.

Fais fab tso zis:Ntsuas nyob rau hauv milliwatts (mW) ib diode. Rau kev kho laser, koj xav tau lub zog txaus los xa cov tshuaj kho mob ( ntsuas hauv Joules lossis J / cm²) hauv lub sijhawm tsim nyog.

Yam Ntau Yam:50mW mus rau 200mW ib diode yog muaj nyob rau hauv cov neeg siv khoom. Lub zog siab dua (piv txwv li, 500mW +) yog siv rau hauv kev tshaj lij / chaw kho mob.

Vim li cas nws tseem ceeb:Lub 100mW diode muab lub zog ob zaug sai li 50mW diode.Sijhawm (seconds)=Dose (J/cm²) / Fais Fab Density (W/cm²).

Beam Hom & Coherence:Muaj tseeb lasers yogsib txuas(lub teeb nthwv dej nyob hauv sync). Ntau tus pheej yig dua "lub teeb liab" siv LEDs, uas yogtsis sib haum.

Qhov zoo ntawm Laser Diode:Lub teeb sib xyaw ua ke tuaj yeem muaj cov ntaub so ntswg zoo dua vim tias tsis muaj qhov tawg (qhov "laser vs. LED" kev sib cav tsis tu ncua, tab sis lasers feem ntau suav tias muaj zog dua rau kev kho mob).

Tseem ceeb:Lub beam ntawm ib tug liab qab laser diode yog heev tsom thiab txaus ntshai rau lub qhov muag.Nws yuav tsum tau diffused los yog tawgua ntej mus txog ntawm daim tawv nqaij los tsim kom muaj kev nyab xeeb, txawm tias qhov chaw kho mob.

Pom zoo Laser Diodes rau RLT daim ntaub ntawv:

Ntawm no yog ib qho kev sib cais los ntawm kev siv cov ntaub ntawv:

1. Rau Cov Kws Tshaj Lij / Chaw Kho Mob- Qib Devices:

Lub wavelength: 808nm los yog 850nm(rau cov ntaub so ntswg sib sib zog nqus), feem ntau ua ke nrog 660nm arrays.

Lub zog: Siab - fais fab ib leeg -emitter diodes, 1W txog 5W+.Cov no feem ntau yog fiber ntau-coupled kom meej xa hauv handheld wands los yog probes.

Piv txwv qhov: Osram PLTB450B(450mW, 808nm) lossis zoo sib xws siab -kev ntseeg siab muaj diodes.

Nco tseg:Cov no yuav tsum tau heatsinking loj, tsav Circuit Court, thiab kev ruaj ntseg interlocks.Tsis yog rau DIY beginners.

2. Rau siab-Cov neeg siv khoom kawg / Ntawm- Cov Khoom Siv Hauv Tsev (xws li, siv tawv, vaj huam sib luag, cov khoom siv tes tuav):

Lub wavelength: Dual 660nm & 850nmyog qhov zoo tagnrho ua ke.

Lub zog: 100mW txog 200mW rau ib lub diodeyog qhov chaw qab zib. Diodes tau teeb tsa hauv arrays lossis pawg kom npog thaj chaw loj.

Piv txwv qhov:Feem ntau5.6mm lossis 3.8mm diode poblos ntawm manufacturers nyiamLuminouslos yogKingbright.

Rau 660nm:L660P200 (200mW, 660nm)

Rau 850nm:L850P200 (200mW, 850nm)

Vim li cas lawv zoo:Lawv muab qhov sib npaug ntawm lub zog, qhov loj me, thiab tus nqi, yog qhov yooj yim, thiab tsim los rau kev koom ua ke rau hauv PCB arrays.

3. Rau qis-Nqis / Nkag mus-Qib Cov Khoom Siv Khoom Siv:

Cov no feem ntau sib tov660nm laser diodenrog850nm LED teeb(los yog siv tag nrho LEDs) kom txo nqi.

Lub zog:Feem ntau50mW rau 100mWrau laser diode.

Piv txwv:Feem ntau3W, 5W, lossis 10W LED- pob khoom styleuas yeej muaj ntau yam tsawg- lub zog laser diode chips. Ceev faj, raws li specs yuav exaggerated.

Qhov tseem ceeb ntawm kev nyab xeeb & kev xav txog kev tsim qauv (Seem tseem ceeb tshaj plaws)

Qhov muag Safety: 660nm thiab 850nm laser teeb yog INVISIBLE lossis NW nyuam qhuav pom ntawm lub qhov muag thiab tuaj yeem ua rau lub qhov muag puas tas li.Txhua yam khoom siv yuav tsum:

Siv adiffuser lens los yog scattering zaj duab xistxhawm rau rhuav tshem txoj kab sib txuas.

suav nroglooj tsom iav dubntsuas rau qhov tshwj xeeb wavelength (piv txwv li, OD6+ rau 808-850nm).

Muaj tus qauv tsim uas tiv thaiv qhov muag ncaj qha.

Tsav Circuitry:Laser diodes yogtam sim no - cov khoom siv tsav, tsis voltage-tsav. Lawv xav tau ibtus tsav tsheb tam sim no tsis tu ncuanrog cov lus pom zoo los tiv thaiv thermal runaway (uas rhuav tshem lub diode tam sim ntawd).

Heatsinking:Laser diodes ua kom sov. Tsis txaus heatsinking ua rau lub zog poob sai (droop) thiab luv lifespan. Lub tshuab cua txias (TEC) yog siv rau hauv siab - cov khoom siv fais fab.

Noj ntau npaum:Qhov no yog lub hauv paus ntawm kev kho kom zoo. Nws nyob ntawm:

Lub zog ceev (mW / cm²)

Lub Sijhawm Kho Mob

Formula: Zog Ceev (J/cm²)=[Power Density (mW/cm²) × Sijhawm (seconds)] / 1000

Lub qhov rais kho yog feem ntau4-60 J / cm², nrog rau cov koob tshuaj rau qhov mob nyem ib ncig10-20 J / cm².
