Lysdioder kan blive dobbelt så effektive om 2 år

80 lumen/watt?

Sjovt nok, sidder da ellers her med 3stk Z-power P7 dioder som har en effektivitet på 90lumen/W.

Ja, det er egentlig skørt. Har også siddet i Teknik fag og set på nogle lysdioder hvor der står 90 lumen/watt...

Men brugen af dem er genial. En 3 farve diode i et multiplex system (vist nok også kaldet et matrix display) er genialt, da det er energibesparende, har en fantastisk kontrast og enorm lumen tilsammen.

Jeg er ikke en ekspert, men måske har de i artiklen målt efter overall luminous efficacy, hvor Seuol semiconductors (der laver Z-power P7) blot har målt efter luminous efficacy. Men det kan selvfølgelig også tænkes at artiklen har villet pynte på tallene.

Under alle omstændigheder er der efterhånden ikke så langt op til det ideelle for hvidt lys, på 243 lm/W

Jeg tror du har ret #3. Ja, det bliver da spændende at se når de rammer hvidt lys... ;) tihi

Hmm! så tror jeg vil ha mig en mere maglite lommelygte til den tid... syntes de godt gode lige nu...så vil være fedt at få den der lyser dobbelt så meget! :D

Det er bare en skam de altid "glemmer" at fortælle om RA værdien* på de nok så smarte LED.
Det er jo det man betaler for når man køber en god gammeldags glødepære.

RA værdien for en Glødepære er på 99
Hvor en LED ligger på omkring 80-90
- det bliver sjovt nok aldrig nævnt.
*Farvegengivelse, Solens lys er per definition 100. Damen kan nok så fint lægge make up på et badeværelse med LED spots men når hun så kommer udenfor, og tjekker det en "sidste" i bakspejlet på bilen ser det helt forfærdeligt ud :)

Hvorfor er 234 lm/W det ideelle for hvidt lys?

Tja, så må man da håbe at lamper og diverse andre genstande som anvender LED teknologi, snart falder i pris så de almene forbrugere vil skifte og spare på energien!

Det kan godt være at det kan betale sig at have LED lys set over en to års periode (fiktive tal) men det er desværre ikke sådan folk regner og tænker ...

"This is the voice of Vrillon, a representative of the Ashtar Galactic Command, speaking to you. For many years you have seen us as lights in the skies. We speak to you now in peace and wisdom as we have done to your brothers and sisters all over this, your planet Earth. We come to warn you of the destiny of your race and your world so that you may communicate to your fellow beings the course you must take to avoid the disasters which threaten your world, and the beings on our worlds around you. This is in order that you may share in the great awakening, as the planet passes into the New Age of Aquarius. The New Age can be a time of great peace and evolution for your race, but only if your rulers are made aware of the evil forces that can overshadow their judgments. Be still now and listen, for your chance may not come again. For many years your scientists, government and generals have not heeded our warnings; they have continued to experiment with the evil forces of what you call nuclear energy. Atomic bombs can destroy the Earth, and the beings of your sister worlds, in a moment. The wastes from atomic power systems will poison your planet for many thousands of your years to come. We, who have followed the path of evolution for far longer than you, have long since realized this - that atomic energy is always directed against life. It has no peaceful application. Its use, and research into its use, must be ceased at once, or you all risk destruction. All weapons of evil must be removed. The time of conflict is now past. The race of which you are a part may proceed to the highest planes of evolution if you show yourselves worthy to do this. You have but a short time to learn to live together in peace and goodwill. Small groups all over the planet are learning this, and exist to pass on the light of the dawning New Age to you all. You are free to accept or reject their teachings, but only those who learn to live in peace will pass to the higher realms of spiritual evolution. Hear now the voice of Vrillon, a representative of the Ashtar Galactic Command, speaking to you. Be aware also that there are many false prophets and guides operating in your world. They will suck your energy from you - the energy you call money and will put it to evil ends giving you worthless dross in return. Your inner divine self will protect you from this. You must learn to be sensitive to the voice within that can tell you what is truth, and what is confusion, chaos and untruth. Learn to listen to the voice of truth which is within you and you will lead yourselves on to the path of evolution. This is our message to our dear friends. We have watched you growing for many years as you too have watched our lights in your skies. You know now that we are here, and that there are more beings on and around your Earth than your scientists admit. We are deeply concerned about you and your path towards the light and will do all we can to help you. Have no fear, seek only to know yourselves, and live in harmony with the ways of your planet Earth. We of the Ashtar Galactic Command thank you for your attention. We are now leaving the plane of your existence. May you be blessed by the supreme love and truth of the cosmos."
