The white light color temperature in the LED advertising module is usually measured in Kelvin (K), and according to the different color temperature, white light can be roughly divided into the following categories:
Warm white: the color temperature is generally between 2700K and 3500K, and the light color is yellowish, similar to the light color emitted by incandescent lamps, giving people a warm and comfortable feeling.
Positive white light: The color temperature is between 4500K and 5500K, the light color is close to natural light, bright and comfortable, suitable for most indoor and outdoor lighting needs.
Cold white light: the color temperature is above 5700K to 6500K, the light color is blue, bright and cold, similar to sunlight under a clear sky.
Second, the difference between different color temperature white light
1. Visual effects
Warm white: Create a warm and comfortable atmosphere, suitable for advertising scenes that need to create a family atmosphere or a relaxing environment, such as advertising in the home, catering and other industries.
Positive white light: provides natural and true lighting effects, suitable for displaying product details or advertising scenes requiring clear visual effects, such as advertising in electronic products, jewelry and other industries.
Cold white: gives people a bright and refreshing feeling, suitable for advertising scenes that need to emphasize the sense of science and technology, modern sense or fresh atmosphere, such as the advertising of science and technology products, fashion brands and other industries.
2. Create atmosphere
Different color temperatures of white light can create a completely different atmosphere. Warm white light is suitable for creating a warm and romantic atmosphere; Positive white light provides a balanced, natural lighting environment; And cold white light can create a fresh, cold atmosphere.
3. Application scenario
Warm white light: suitable for family homes, bedrooms, restaurants and other places that need to create a warm atmosphere.
Positive white light: widely used in commercial displays, office places, public places and other scenes requiring clear lighting and good visual effects.
Cold white light: suitable for outdoor advertising, science and technology exhibitions, modern art exhibitions and other scenes that need to emphasize modern and scientific sense.
4. Visual comfort
Visual comfort is closely related to the choice of color temperature. Too high a color temperature (such as cold white light) may give people a harsh feeling, affecting the viewing experience; And too low color temperature (such as warm white light) may cause the picture to be yellow, affecting the color reproduction degree. Therefore, when selecting the color temperature of the LED advertising module, it is necessary to comprehensively consider the specific application scenarios and audience needs.
To sum up, white light with different color temperatures has a significant difference in LED advertising modules. These differences are not only reflected in the visual effects and atmosphere, but also directly affect the choice of application scenes and the visual comfort of the audience. Therefore, when choosing the color temperature of the LED advertising module, it is necessary to make a scientific and reasonable choice according to the specific needs and scene characteristics.
