To determine whether an LED light is full spectrum, you can consider several aspects of spectral integrity, color rendering index, spectral distribution, product identification and certification, and actual use experience. Take a look.
What is spectral integrity
Full-spectrum LED lamp refers to the spectrum contains ultraviolet light, visible light, infrared light spectral curve, and in the visible part of the red, green, blue ratio and sunlight approximation, the color rendering index is close to 100, the sun's spectrum can be regarded as a model of the full spectrum, and its spectral curve is continuous and complete. Therefore, the first criterion to judge whether the LED light is full spectrum is to observe whether its spectral map is continuous and complete, and whether the distribution of monochromatic light is full and even.
What is the color rendering index
Color rendering index (Ra) is an important parameter to measure the color rendering ability of a light source, which indicates the ability of the light source to reproduce the color of an object. The color rendering index of a full-spectrum LED lamp should be close to or reach 100, which means that it can accurately reproduce the true color of an object in sunlight. If the LED lamp has a low color rendering index, it may not be able to render the full details of an object's color, thus affecting the visual effect.
How the spectrum is distributed
In addition to the overall color rendering index, you also need to pay attention to the spectral distribution of LED lights in the visible range. Full-spectrum LED lights should have a balanced energy distribution on the three basic color light bands of red, green and blue to ensure soft and uniform light. At the same time, its spectrum should also contain an appropriate amount of ultraviolet and infrared components to simulate the natural light environment.
Product labeling and certification
Formal full-spectrum LED light products will usually be clearly marked on the packaging or instructions of its spectral characteristics and color rendering index and other information. In addition, some authoritative organizations will also certify and test LED light products to ensure that they meet the full-spectrum standards. Therefore, when purchasing, you can choose products with relevant certification marks to increase the confidence and security of purchase.
Actual use experience
Finally, the actual use experience is also an important basis for judging whether the LED lights are full spectrum. Full-spectrum LED lights can present a more natural and comfortable light effect when lighting, reducing eye fatigue. If the light is harsh or the color is distorted during use, the LED light may not be a full-spectrum product.
To determine whether an LED light is full spectrum needs to be considered from spectral integrity, color rendering index, spectral distribution, product identification and certification, as well as the actual use of experience and other aspects. When choosing, it is recommended to prioritize regular brands and products with relevant certification marks to ensure their quality and performance.
