The color temperature of the Lighting Fixture

Color temperature is a unit of measurement that indicates the color components contained in light. Theoretically, color temperature refers to the color of an absolute blc after it is heated from absolute zero (a 273°C). Black body after being heated, gradually from black to red, to yellow, to whitish, and finally to blue. When heated to a certain temperature. The spectral component of the light emitted by a black body. It is called the color temperature at this temperature, and the unit of measurement is "K" (Kelvin). If the light emitted by a light source contains the same spectral composition as the Lighting Product emitted by a black body at a certain temperature. For example, the color of a 100 W bulb is the same as the color of the absolute black body at 2527K, then the color temperature of the light emitted by this bulb is: 2527K + 273K = 2800K

Color temperature is a temperature measurement commonly used in physics and astronomy, a concept based on a fictional black object that emits different colors of light when heated to different temperatures, and its objects appear to be different colors. Just like when you heat an iron block, the iron first turns red, then yellow, and finally white.

The color temperature indexed using this method is the opposite of what the general public perceives as "warm" and "cold", for example, people usually perceive red. Orange and yellow are warmer, white and blue are cooler, while in fact red has the lowest color temperature, and then gradually increases orange, yellow, white, and blue, with blue being the highest. When shooting with natural light, the color temperature of the light varies depending on the time of day, so the color of the photo is not the same. For example, when shooting under a clear blue sky, the photo has a cooler tone due to the higher color temperature of the light; On the other hand, if you shoot at dusk, the color temperature of the light is low, so the photo has a warmer tone. When shooting with artificial light, there may be cases where the color tone of the photo is different depending on the type of light source.

Understanding the relationship between light and color temperature helps photographers shoot in different lighting conditions, calculate in advance what hues will be captured, and further consider whether to intensify or attenuate this tone, and which camera features should be used to intensify or weaken this tone when actually shooting.

The color temperature of the light source is different, and the feeling is different. Under high color temperature light source. If the brightness is not high, it will give people a cold feeling; Under the illumination of a low color temperature light source, too high brightness will give people a stuffy feeling. The lower the color temperature, the warmer the hue (reddish); The higher the color temperature, the cooler the hue (bluish).

Color temperature (color temperature) is a characteristic of visible light with important applications in photography, video, publishing and other fields. The color temperature of a light source is determined by comparing its color with a theoretical hot black body radiator. The Kelvin temperature when a hot black body radiator matches the color of a light source is the color temperature of that light source, which is directly related to Planck's black body radiation law.

The most suitable color temperature range of LED lighting fixtures(Indoor Lighting and Outdoor Lighting) should be close to the color temperature range of the sun's natural white light is the most scientific choice; Natural white light with lower irradiation intensity can achieve irradiation effects that are incomparable to other non-natural white light; The most economical pavement brightness range should be within 2cd/m2; Improving the total uniformity of lighting and eliminating glare is the most effective way to save energy and reduce consumption.
