Bold: blackbody radiation

 2. Bold: blackbody radiation energy of a hypothetical, in the evaluation of other radioactive   LED Bulb  sources, the use of it as a relatively light and reference light, which is a temperature of the radiation depends only on the radiator. Such a body, which can at any temperature to which the radiation at any wavelength on the surface of all the energy absorption. In other words, any temperature in the radiator, the absolute blackbody spectral absorption rate are equal to 1.

For example, if a hole is completely closed rooms marked incident light, the light will continue to  LED Module reflect on the wall, but will not return to the original hole, and all radiation to the inside. If a piece of metal into the cavity of the Chi-li, is internal irradiation, the light will not be reflected to the outside. If this change in the freezing point of the metal block of platinum into the cavity, which in turn radiation without radiation, it can be defined as a blackbody such voids.   LED Flexi Strip Has a very small peephole generally close to the cavity blackbody.
