What are the characteristics of reflective lampshades?

The shadowless lamp on the operating table can also be seen as concentrating many light sources from different directions to a single point.

What are the advantages of xenon flash compared to LED flash?

As the brightness of LED light-emitting diodes is much lower than that of real flash lights, they can only play a "fill in" role. LEDs do not emit light through electron transitions within atoms, but rather by applying voltage to both ends of the PN junction of the LED, causing the PN junction itself to form an energy level at which electrons jump and produce photons to emit light.
