Breakthrough In LED Construction Increases Efficiency By 57 Percent
Zothecula writes: With LEDs being the preferred long-lasting, low-energy method for replacing less efficient forms of lighting, their uptake has dramatically increased over the past few years. However, despite their luminous outputs having increased steadily over that time, they still fall behind more conventional forms of lighting in terms of brightness. Researchers at Princeton University claim to have come up with a way to change all that by using nanotechnology to increase the output of organic LEDs by 57 percent.
Easily fixed with a piece of electrical tape - to hold your eyes shut.
There is a company that makes lightdims, which are like tinting stickers that you can put over LEDs to dim them (block some of the light). They come in different strengths, even blackout.
I use them on the computers and other electronics in my bedroom since the LEDs collectively put out so much light it's hard to sleep.
...because it doesn't pay very well to sell you something that'll last forever, whether it's an Oled screen or LED bulb.
:(
It's no coincidence that the CFLs die off after 1-2 years albeit they're supposed to last 10-20 years with normal usage. My first Philips 11w CFLs that I bought 20 years ago, still glows like mad and simply refuse to die. That is back when the CFLs was new, and cost like 40 bucks just for ONE bulb, but hey...it's actually worth the money, it still is my best bulb.
With LED's, it's a walk in the park for the industry to make them last less, all you need to do for your LED to last less than specified, is to OVERDRIVE them just a little, a little higher current and the LED's will die rapidly, they should be able to make the new LED lamps last just out the warranty period (that in most countries AFAIK is around 3-6 months), or cheap enough to avoid the warranty altogether.
There is nothing wrong with the LED's themselves, (we're talking the components...DIODES...not the whole circuit with drivers and all), I ordered strong RGB leds from China many MANY years ago, they're still glowing on my homemade alarm-systems so strong that I can use them as night-lights, yes...4 years later 24H day use...they still glow enough to lit up an entire room. And I just used Ohms law + 1% resistor values to calculate the right resistor value for my circuits. You can pretty much BET the manufacturers will "miscalculate" these values, or make the drivers for the stronger LED's last MUCH less in order to keep pumping out new ones for the consumers to waste and waste.
I'd rather pay a proper price for my LED lamps - and keep our environment safe from this mad overproduction that now has escalated totally out of hands.
What this world is coming to - is for you and me to decide.
This is quite funny. Though refrained taping my eyes shut (and I'm not a vampire), I did just last night, go around my room and put pieces of black electrical tape over every LED light I could find sans the clock (which dims in the darkness thank goodness). It's amazing just how sensitive your eyes are to light pollution at night. Every power bar I have has a glowing light of some kind. One even has two. I have a wireless extender that has several LEDs on it. Then there's the TV, the TV cable box, a heater...everything got the electrical tape band aid treatment. I even put a black screen wipe over my cell phone in it's charger cradle that likes to let me know it's charged by beaming me in the face with green light. Tablets get charged with their cases closed and the laptop charger goes face down into the carpet. When I charge my electric shaver or toothbrush, they get turned upside down to shine their light into themselves. Made a HUGE difference to the point where I have to feel my way around if I shut off the lights too soon.
I've had to get obsessive compulsive about this just so I can get a decent sleep...but it's worth it!
