The light bulb, every household has one, because with it, people no longer have to "feel the dark" in the dark night. So, how many people know about light bulbs? Next, in order to let you know more about the light bulb, we will talk about the "light bulb in different color temperature light color is not the same" point of knowledge.

So, what is color temperature and light color?

Color temperature is the human eye on the luminous body or white reflector feeling, usually in K as a unit, is a complex combination of physics, physiology and psychology of a feeling, is different from person to person. And light color refers to the "color of the light source", or several light sources combined to form the "light color component" of the subject environment. And the relationship between them is complex, it is difficult to use the "easy" formula to explain the relationship between the color temperature of the highlands and the change of light color. Therefore, we take the very popular 7W bulb lamp as an example.

1, low color temperature: color temperature below 3300K, light color reddish will give a sense of warmth, but also to create a stable atmosphere; when irradiated with low color temperature light source, can make the red more vivid.

2, the color temperature: color temperature in 3000 ~ 6000K, people in this hue no special obvious visual psychological effect, and a sense of refreshment, also known as the "neutral" color temperature. When the use of medium color temperature light source irradiation, so that the blue has a sense of coolness.

3, high color temperature: when the color temperature exceeds 6000K, the light color blue, will give a sense of cool. When the use of high color temperature light source illumination, it will make the object has a cold feeling.
