Flashing Light

The main idea is to use not constant but flashing light to economize electric power. Big duty cycle reduces power consumption about 20 times.

   Another feature is to use bright LEDs. Today LEDs are most effective lighting devices on the market. For used Amber LED efficacy of lighting with driver and heating looses included is about 47 lm/W. For comparison most effective halogen lamps give 28 lm per watt.

   Some simple drawing of mechanical is made in picture below. There is 3 cutoff boards placed on sides of equilateral triangle. This arrangement provides circular lighting. The LEDs attached to the boards through the hole in the center. Extra caution must be taken during bringing together boards. To avoid shorted circuit and not provided connections.
