Different color temperatures correspond to different colors, so you can judge the approximate temperature by color. For example, metal workers can judge the temperature of molten iron based on its color. The human brain also behaves differently at different color temperatures: more spirited under high color temperature (daytime) lighting, calmer under low color temperature lighting Refers to the color of the bulb when it is lit, that is, the color that appears after a standard black body starts to heat at -273 degrees Celsius. After the black body is heated, it slowly changes from black to red, then to yellow and white, and finally a blue light source appears. When heated to a certain temperature, the spectral factor contained in black body light is called color temperature. When buying light bulbs, don't just buy them casually. The area of the use area and the area of the dark area, the design of the lampshade needs to be considered. Since these all have a certain impact on the brightness of the bulb. For example, if it is a light-transmitting PC lampshade, this design adopts an arc-shaped light-transmitting design, which can better reflect the brightness of the lamp. After the black body is heated, it slowly changes from black to red, then yellow and white, and finally a blue light source appears. When heated to a certain temperature, the spectral factor contained in the light of the black body is called the color temperature.
