What does the LED lamp color temperature mean?
The color temperature is the scale of light source, the unit is K (Kelvin)!
In physics, the color temperature refers to a standard blackbody heating, temperature rise to a certain degree when the colors began by the crimson-red-orange-white-blue, gradually changed, a light source and the color of the black body at the same time, LED lamp we will be the absolute temperature of the black body at that time is called the Light Color temperature is an important application in the fields of photography, video and publishing. Color temperature points warm white, natural white (white), white and so on.
LED light temperature refers to the color of LED lights, generally divided into, warm white (2700k-4500k), White (4500-6500k), White (6500K above) three kinds.
The light that is usually seen by the human eye is composed of 7 kinds of spectrum. But some of the light is blue, others are red, LED lamp and the color temperature is a way to measure and calculate the colour components of light. How to accurately position color temperature? This requires the use of a "color temperature meter". Normally, at 10 noon to 2 o'clock in the afternoon, the cloudless sky, in the absence of direct sunlight, standard daylight is about 5200~5500°k. The color temperature of the news photographic lamp is in the 3200°k; LED lamp the color temperature of the tungsten and general light bulbs used in the tungsten and photo studio is about 2800°k; Because of the low color temperature, the photo taken in this case will feel yellow when it is printing out. and the color temperature of the general fluorescent lamp around 7200~8500°k, so the photo taken under the fluorescent lamp will be partial cyan.
