O le mea fou o le LEDs (diodes light emitting) o se faʻagasologa faʻasolosolo e aofia ai sao mai le tele o saienitisi. O nisi nei o taimi iloga fa'asolopito i le mea fou o LED:
Muamua a'oa'oga ma su'ega:
1907:Na matauina muamua e le saienitisi Peretania o HJ Round o le semiconductor material silicon carbide (SiC) e fa'amumuina le malamalama pe a fa'aoga le eletise. Ole mea muamua lea na fa'amauina ole electroluminescence o mea fa'amea semiconductor.
1920s:Sa suʻesuʻe atili e le saienitisi Rusia o Oleg Losev le mea mataʻutia ma lolomiina se pepa i luga o mataupu faavae o le LED i le 1927, ae e leʻi tosina atu ai le lautele o tagata i lena taimi.
Atina'e o LED fa'atino:
1962:O Nick Holonyak Jr., o se enisinia galue i le General Electric (GE) i lena taimi, na ia faia le uluai moli malamalama faʻaaogaina (LED mumu). Holonyak ua lauiloa o le "Tama o LED".
1972:M. George Craford, o se tamaititi aʻoga o Holonyak, na ia fatuina le LED samasama muamua ma faʻaleleia atili le susulu o moli mumu ma moli. Na ia faia ni faʻaleleia atili e faʻavae i luga o le gallium nitride phosphorus (GaAsP) mea e faʻateleina ai le susulu o LED faʻasefulu.
1970s ma 1980s: O le faʻalauteleina o tekinolosi na taʻitaʻia ai le fausiaina o LED i le tele o lanu, e aofia ai lanu meamata, samasama, ma moli.
La'ei lanu moana Fa'atosina:
1990s:Saienitisi i Hitachi ma Nichia, aemaise Shuji Nakamura, na faia ni moli lanu moana maualuga. O se mea taua tele lea i le fa'aaogaina o meafaitino gallium nitride (GaN). O le mea fou o LED lanumoana na faʻaalia ai lanu lanu atoa ma faʻamalama paʻepaʻe e mafai.
2014:Shuji Nakamura, Isamu Akasaki, ma Hiroshi Amano na maua le Nobel Prize in Physics mo la latou galuega i luga o moli lanu moana.
Atina'e o LED Pa'epa'e:
E masani lava ona fa'atūina fa'amalama pa'epa'e e ala i le tu'ufa'atasia o LED lanumoana ma phosphors. O le moli lanumoana mai le lanumoana lanumoana e faʻaosofia ai le phosphor, ona faʻauluina lea o le moli samasama, ma o le tuʻufaʻatasia o le lua e maua ai le malamalama paʻepaʻe.
O le alualu i luma i tekinolosi LED ua mafua ai le tele o lanu LED e le gata i le vaʻaia, ae faʻapea foi i le ultraviolet ma le infrared ranges. I aso nei, o loʻo faʻaaogaina LED i le tele o talosaga, e aofia ai faʻaaliga, moli, moli faʻaalia, ma fesoʻotaʻiga.
O loʻo faʻaalia i lalo le faʻavasegaga autu ma le faʻaogaina o le LED
