The commonly used color temperature standards for LED displays mainly include the following, and each color temperature standard has its specific application scenarios and effects:
Definition of color temperature
Color temperature is a physical quantity that represents the color of the light source, and the unit is Kelvin (K). Color temperature is the heating of a standard black body. When the temperature rises to a certain degree, the color of the black body gradually changes from dark red to light red to orange-yellow to white to blue. When a certain light source has the same color as the black body, the temperature at which the black body is heated is called the color temperature of the light source, referred to as "color temperature".
Common color temperature standards
1. Warm white light (2700K-3500K)
- Features: The color is reddish, giving people a warm and comfortable feeling, and can create a warm and soft atmosphere.
- Application scenarios: Suitable for bedrooms, living rooms, restaurants, cafes, and other places that need to create a warm and comfortable atmosphere. In addition, low color temperature light sources can make red objects more vivid.
2. Natural white light/neutral white light (3500K-5500K)
- Features: Between warm white light and cold white light, the tone is white, neither too soft nor too glaring, and more natural.
- Application scenarios: Widely used in places that require a more natural and bright lighting environment, such as office buildings, shopping malls, schools, factories, etc.
3. Cold white light (5500K-7500K)
- Features: The light color is bluish, relatively bright and glaring, and can provide higher lighting brightness.
- Application scenarios: Suitable for places that require high-brightness lighting, such as hospital operating rooms, factory workshops, outdoor squares, etc. In addition, cold white light is also suitable for rooms dominated by cold colors such as blue, green, and purple.
Color temperature and visual psychological effects
- Low color temperature (below 3300K): There is a stable atmosphere and a warm feeling.
- Intermediate color temperature (3000K-5000K): People have no particularly obvious visual psychological effects under this color tone, and have a refreshing feeling, so it is called "neutral" color temperature.
- High color temperature (above 5000K): The light color is bluish, giving people a cool feeling.
Notes
- When choosing the color temperature of the LED display, it is necessary to decide according to the specific application scenario and needs. For example, in places where a warm atmosphere needs to be created, warm white light can be selected; in places where bright lighting and high concentration are required, cold white light can be selected.
- At the same time, it is also necessary to consider the combination of the brightness and color temperature of the light source to ensure that the lighting effect is optimal. For example, if the brightness is not high under the irradiation of a high color temperature light source, it may give people a gloomy feeling; and if the brightness is too high under the irradiation of a low color temperature light source, it may give people a stuffy feeling.
In summary, the commonly used color temperature standards for LED display screens include warm white light, natural white light/neutral white light and cold white light. Each color temperature standard has its own unique characteristics and application scenarios. When choosing, it is necessary to make comprehensive considerations based on actual needs.
