The hope of Christmas begins with the stars in the sky and has evolved into the lights we hang on the Christmas tree.
Conceptually, the symbols of a light bulb represent an idea or inspiration.

Light Emitting Diode)
We are used to seeing in dashboards, light switches and computers that are growing slowly and steadily, and thus becoming stronger in lighting.
The research of LED technology is developing towards improving the output of LED light.
One advantage of LEDs is that they produce "cold light" and do not waste energy.
So far, LED cannot match the bright white light of incandescent fluorescent lamp.
But bright white LED lights are on the horizon.
