A sunrise and sunset lamp with LEDs

Step 3What is sunset looking like?

What is sunset looking like?
When you observe a real sunset you might recognize that the colour of the light is changing over time. From a bright white when sun is still over the horizon it changes to a bright yellow then to a medium orange then to a dark red and after that a low blueish white glow, then there is darkness.

The sunset will be the most difficult part of the device because you watch it with full consciousness and little mistakes are quite annoying. Sunrise is principally the same program reversed but as you are still asleep when the sunrise starts, we don't have to worry too much about colours. And starting your sunset when laying down, you might not want to start out with bright sunshine but in the morning it is important to get the most out of the LEDs. So it is convenient to have different sequences for sunrise and sunset, but you are free to test anything you like of course!

But these differences in the programs, might lead us to a different selection of LEDs for both programms.
