RE: Đèn xenon Phillips cho C200 - Chùm ảnh out of the box
To understand use of the Kelvin scale, you must first define what a "Black Body Radiator" does. At absolute zero - minus 273.3 ° Centigrade - this theoretical object radiates no energy. As the temperature of "Theoretical Black Body" is raised, it begins to emit energy. At about 700° C, a faint red glow becomes visible to the naked eye. As the TBB's temperature is raised to about 1517° C, it glows with a light similar to candle or firelight, 1800° K. (We started at minus 273° C and raised the temperature of the Theoretical Black Body to 1517° C - the result 1800° K). Continuing to raise the temperature will cause the Kelvin factor to rise: first to 2850K, a typical household incandescent lamp; then to 3200K, a typical studio incandescent lamp; and finally on to 5600K, nominal daylight. The Kelvin scale continues to rise to a blue sky of 28,000K
Chữ K không phải là giá tiền, mà biểu thị nhiệt độ, độ Kelvin !
