luminous energy การใช้

In other systems of units, luminous energy may be expressed in basic units of energy.
The SI unit of luminous energy is the lumen second, which is unofficially known as the talbot in honor of William Henry Fox Talbot.
The first paper proposed the idea of " luminous energy could only be absorbed or emitted in discrete amounts, called " quanta ".
Ungoliant used it to satiate her infinite hunger for luminous energy, and also to hide herself and Morgoth, making both of them invisible to the Valar.
Her painting creates a feeling of suspended time or, as art critic, Carter Ratcliff commented, " a pause between the pulses of some vast and luminous energy . " A reproduction of her work appears in the seminal art history text, The Art of Seeing, 3rd through 6th editions, published by Prentice Hall.
