The editor thinks that LED lens moduleProduct,An important specification number is color temperature,This is related to LEDlens module productionThe color characteristics displayed by the product, general LED lens modules also have color temperature specifications. The unit of measurement for color temperature is KelvinScale, that is, in units of K, At the beginning, Kjeldahl observed in the steel plant that when the molten metal begins to reach the highest temperature, the color of the metal lightening is different, and it is recorded in data units. Down, and later produce the specification sheet of LED lens module.

1. Definition of color temperature:

Expressed in absolute temperature K, that is, heating the standard black body, when the temperature rises to a certain extent The black body color starts out dark red-lightred-orange -white- Blue,change gradually,When a light source has the same color as the black body,We call the absolute temperature of the black body the lightThe color temperature of the source.

2. Color temperature under different light source environments: The following is a common oneLEDColor temperature comparison table for lighting fixtures:

LED lens modulelight color at different color temperatures:

1, low color temperature: color temperature at 3300Kbelow, the light color is reddish to give a warm feeling; there is a stable atmosphere, a warm feeling; when Use a low color temperature light source to illuminate , to make the red more vivid.

2, medium color temperature: the color temperature is 3000--6000K is in the middle, people have no particularly obvious visual psychological effect under this tone, and they have a refreshing feeling; so it is called < /span>"neutral"Color temperature. Gives blue a cool cool when illuminated with a medium color temperature light source.
