We all want multiple output LED lights. Obviously.
Here's why: to be able to adjust the light output to our needs, meaning little output for close-up and a big nasty punch to spot the dog far away. To avoid being blinded by an insane hot-spot while working on our desk and to be able to light up the whole room with the same light nevertheless.
In the end, it comes down to the simple wish to maintain a more or less constant light input to out eyes, enabling us to see things at a sufficient illumination either near or far away.
Now ... my point:
Basically the goal is to achieve a constant light-input to our eyes that needs less output for close-up tasks and more punch for things far away. This amount of light our eyes need to see clearly is the same for near and distant objects, you just need more light energy to achieve this goal according to the laws of physics when the target is further away.
So ... with multiple output levels we can achieve this ... by changing the output according to the needed input. This is an insufficient solution IMHO. This would be a light that requires attention and tweaking while at work, it actually distracts from the task the user might be working on and, in case of improper use, may even have adverse results, such as accidently loosing your adapted vision when shining the high beam at something close.
Here's the solution:
Build a light that defines its output according to what our eyes see, according to the input level. Sounds impossible? Why?
With all those fancy computer-controlled lights around (Eternalight, LS4, ...), the solution is simple. Just install a photo-diode or something that can measure light-intensity at the front end of the light, shield it from the beam, and have the electronics adjust the output according to the measured input level automatically. This would be same input that your eyes see, the light reflected from the target of the beam. If you swing your light around, it will automatically dim when hitting a closer target and brighten when shining it on something far away. For you (your eyes) it would result in an illumination level that is always at the same intensity, thus preserving your vision and making it unnecessary to fumble with your light to adjust the output. It might save battery power, too.
You could even take this concept one step further and allow for selectable INPUT levels that represent really the light intensity that you need, and not an output level that might be inadequate a second later when moving your light around.
Basically, this concept takes a more physiological approach to what we need, the definition should be INPUT to our eyes and not OUTPUT, this is just a poor construct to achieve the true goal, which is not what a device can do, but what it can do for us to accomplish a task. That would include the sensory input as the important variable to discuss, and not output, which is the dependent variable and should be handled by the device itself without the necessity of constant monitoring by the user.
What do you think?
