Wireless light with WiTricity

With wireless light this is a space to watch: wireless power transfer for two reasons.

One it is new but old of course just the way we like it. Its inventor Marin Soljacic - smiling in the middle - calls it WiTricity for wireless electricity. But the idea is coming all the way from Nicola Tesla (what doesn't these days :-) who envisioned a time when electricity would be transmitted via broadcast just like radio.

The team is positioned in the path between the coil that broadcasts power wirelessly and the receiver coil attached to the 60W light bulb.

Now it that bulb is a LED bulb, and the coil approximately 50 times smaller, you are onto something. It is just a matter of time. This is the other reason to watch this space.

Electricity consumed in a commercial building for lighting is 35% of total electricity and it accounts for 12-15% average household energy bill. LED bulbs consumes less watt to operate, long life 30000 to 50000 hrs compared to an incandescent bulb 2000 hrs. Made from non-toxic materials disposal is not an issue. Electricity consumption is one tenth of incandescent bulb and less than half of CFL. No UV and RF radiation, lesser carbon dioxide emission almost half of the CFL. LEDs can withstand high levels of shock and vibration. Its able to convert almost all the energy used into the light output, LEDs generate less than 30% of the heat of traditional lighting technologies . LEDs, being solid state components, are difficult to damage with external shock.

Thanks for your information.LED light bulbs can deliver the same brightness as incandescent bulbs do with only 10% energy consumption as incandescent bulbs’. LEDs are brand new light source with a luminous flux of over 100 lumen per watt for indoor lighting.

Well that's imagine, wireless powder transformation. But how much power efficient this system will be? Although, you are using LED LIGHT BULBS, I think there will be huge loss of electricity. Do you guys working on this issue? I mean saving power.

There are many benefits that come with LED lights. Common benefits include: energy saving. Since the lights don’t require constant supply of energy, they require just minimal power which saves you plenty of money that you would have paid for your power bills. The other benefit is that the lights can produce any of your desired colors without applying a filter. This is because all you need to do is to add a colored impurity, and the light will give your desired color. The other benefit is that the lights are long lasting. This is because they are usually encased in plastic thus they are protected from damage.

How does this lighting system work with LED lights? It seems to be efficient. Does it affect electricity bills greatly? It seems like it would decrease electricity usage.

Led Light We got a couple of these to add to our band's stage lights. We use them more like accent lights. They're small and really affordable. We like them.

I didn't know that the Led light could be up to 50 times smaller. That would save a ton of space. I know that I could definitely benefit from this. http://ledequipped.com
