Chiedza chekurapa chirwere chinoverengerwa neiyi formula:
Simba Density x Nguva = Dose
Neraki, zvidzidzo zvenguva pfupi yapfuura zvinoshandisa zviyero zvakamisikidzwa kutsanangura protocol yavo:
Simba Density mumW/cm² (milliwatts per centimeter squared)
Nguva mu s (masekondi)
Dose muJ/cm² (Joules per centimeter squared)
Kurapwa kwakareruka kumba, kuwanda kwesimba ndicho chinhu chikuru chaunofanira kuziva - kana iwe usingazvizive, hauzokwanisi kuziva kuti ungaisa mudziyo wako kwenguva yakareba sei kuti uwane imwe dosi.Ingori chiyero chekuti chiedza chakasimba sei (kana kuti mafotoni mangani ari munzvimbo yechadenga).
Nemakona ekubuda ma LED, mwenje uri kupararira kunze sezvaunofamba, uchivhara nzvimbo yakafara uye yakafara.Izvi zvinoreva kuti kusimba kwechiedza panguva chero ipi zvayo kunoderera sezvo chinhambwe kubva kunobva kuchiwedzera.Misiyano mumakona emakona pa LEDs inokanganisawo kuwanda kwesimba.Semuyenzaniso 3w/10° LED ichaita mwenje wemagetsi density mberi kupfuura 3w/120° LED, iyo inoburitsa chiedza chisina kusimba panzvimbo hombe.
Zvidzidzo zverapi rechiedza zvinowanzo shandisa simba rema ~ 10mW/cm² kusvika pakakwirira ~200mW/cm².
Dose irikungokuudza kuti inguva yakareba sei iyo density yemagetsi yakashandiswa.Higher light intensity inoreva kuti nguva shoma yekushandisa inodiwa:
5mW/cm² inoshandiswa kwemasekonzi mazana maviri inopa 1J/cm².
20mW/cm² inoshandiswa kwemasekonzi makumi mashanu inopa 1J/cm².
100mW/cm² inoshandiswa kwemasekonzi gumi inopa 1J/cm².
Aya mayunitsi emW/cm² uye masekonzi anopa mhedzisiro muMJ/cm² - ingowanza izvozvo ne0.001 kuti upinde muJ/cm².Iyo yakazara fomula, uchifunga akajairwa mayunitsi saka:
Dose = Simba Density x Nguva x 0.001
