Solid state lighting - saves lives- and it improves life .

Yet more from the realm of LED lighting-

 Many folks are seeing LEDs - it's hard to avoid contact with 'em.

A growing proportion of cars utilize the array of lighted dots - ie Audi products.

They are in folks homes as in LED televisions - and the on topic point

for this audience is you're seeing them in overhead , standard form factor lamps.

Wonderful -

 

 Here are a few wrinkles on their use that are saving lifes or making life better:

 

the Ohio dept of transportation (ODOT) has begun fitting out their snowplows with

a distinctive green LED - the light from this wrinkle allows drivers to better gauge

distance by enhancing depth perception elements - Its early but it's a new accident

reducing scheme.

- Or the gravity LED - using a / weight/ dynamo/ LED combo an altrusic concern is

generating the energy from these simple devices to provide lighting for rural, destitue

folks- the extra hour or so of light is helping in the quest to bring more viable hours

of productivity to places relaint on (expensive for them) kereosene.

Or - how about using OLEDs embedded in gauze to help patients with skin disorders-

medical science is garnering great results with an innovation that helps skin cancer patients

and those suffering from dermal maladies to heal - very quickly + effectively by use

of a specific "light therapy.

 

THese and many other applications are taking off - using LED in light boxes and/or

special ambiant lighting for relief from that medical problem SAD-

 

Yes the lighting gains for standard "bulbs or lamps are something" we in the SSL industry

know it to be "the TIP OF THE ICEBERG"

LED lights are the future for automotive also there are tons of aftermarket LED accessories available for cars like interior LED bulbs for car map lights, dome lights and more, LED tail lights, fog lights, even LED headlamps.

It is okay as long as you remember  both green and red are the colors that can not be seen by those with color blindness.  And that visual defect occurs more commonly in men.  

Do you know if they are adding the color for the front of the vehicles to make the road more visible for the plows... or the back to make the vehicle more visible for the drivers behind them?

Dennis McCarthy,  not sure if you've seen this...

"Cree Sheds Light on Development of a 200-Lumen-per-Watt Luminaire Prototype
The lighting manufacturer surpasses a Department of Energy benchmark set for 2020.

By Hallie Busta"

"Last month, Cree announced the development of a 3000K, 3,200-lumen concept luminaire that achieves 200 lumens-per-watt at a CRI of 80 at thermal equilibrium. The prototype, which is AC-powered, is the first 200 lumen-per-watt concept luminaire, the company says, surpassing a benchmark forecast by the Department of Energy and not expected to be surpassed until 2020. The announcement, which follows Philips’ development of a 200 lumen-per-watt prototype replacement lamp last spring, is evidence of continued efforts by lighting manufacturers to produce more efficient LED luminaires for commercial applications. Architectural Lighting spoke with Greg Merritt, Cree’s vice president of marketing for lighting, about how developments such as the company’s new concept lamp are accelerating commercial LED "adoption. 

"Is the 200 lumen-per-watt output achieved with a 1W LED?
We don’t characterize our LEDs that way. They’re designed to be driven at a range of power levels depending on what the designer is trying to accomplish. This luminaire is 3200 lumens at 16W. "

In my observation, In most of the lightning appliances led bulbs are used because of their advantageous features. Mostly, Everyone is searching for quality and affordable lights, so led lights will cover these aspects and becomes too selectable lights for customers.
