Difference between full-spectrum white light and positive white light

According to Qijia's inquiry. Com, the main difference between full-spectrum white light and positive white light is:

1. spectral components: full-spectrum white light refers to white light with good spectral continuity and low loss rate, which is infinitely close to sunlight in the visible range. Positive white light refers to white light with a color temperature of 4000~4500K, also known as neutral white light or natural white light.

2. Color rendering performance: The color rendering performance of full-spectrum white light is better than ordinary white light, because full-spectrum white light can better restore the true color of objects and the skin color of human body, especially for colors with high saturation, such as red, blue and green. The color rendering performance of positive white light is general, and it has strong reduction ability for colors with moderate saturation and lightness, such as yellow, orange and purple.

3. Application scenario: Full-spectrum white light is suitable for photography, painting, exhibition halls, museums, luxury stores, mahogany furniture stores and other occasions that require high color reproduction. Positive white light is suitable for general lighting occasions, such as offices, classrooms, conference rooms, libraries, etc.

To sum up, the difference between full-spectrum white light and ordinary white light lies in the different spectral composition, color rendering performance and application scenarios, and there is no absolute good or bad, so it should be selected according to different needs and preferences.
