Sådan spreder du lys fra LED

LED (Light Emitting Diode) er en solid-state halvlederenhed, der direkte kan konvertere elektricitet til lys.

LED-chip

Hjertet i LED’en er en halvlederwafer. Den ene ende af waferen er fastgjort til et beslag, den ene ende er den negative elektrode, og den anden ende er forbundet til den positive elektrode på strømforsyningen, så hele chippen er indkapslet af epoxyharpiks.

En halvlederwafer er sammensat af tre dele, den ene er en halvleder af P-type, hvor huller dominerer, og den anden ende er en N-type halvleder, som hovedsageligt er elektroner, og der er normalt 1 til 5 periodiske kvantebrønde i midten.… Read More

Kuumenevatko LED-valot

Kuinka kuuma LED-lamppu on?

Se tuntuu kosketettaessa kuumalta, mutta ei niin kuumalta kuin CFL-lamput, halogeenilamput ja hehkulamput. LED-lamput ovat yksi uusimmista ja tehokkaimmista valaistustekniikoista. Verrattuna edellisen sukupolven polttimoissa käytettyyn kuumahehkulankaan suuritehoisten valaistus-LEDien tuottaman valon käyttölämpötila on paljon alhaisempi. LED-polttimoiden kuumin ulkopinta on yleensä puolet saman kirkkauden hehku- tai korkeapainenatriumlampun lämpötilasta, mikä on noin 36 % loistelampun lämpötilaa alhaisempi.
