Features and Applications of Full Spectrum LED

The full-spectrum LED greatly enhances the continuity and integrity of the spectrum by complementing the missing short-wave violet, cyan, short-wave green, and long-wave red light spectra, making the color gamut wider and closer to the full spectrum of sunlight.

Short-wave violet light helps the human body to synthesize vitamin D and promote the body's absorption of calcium. The purple light with a wavelength of 400~420nm also helps plants form anthocyanins and resist the elongation of branches and leaves. Long-wave "red light" can promote the overall growth of plants during the flowering and fruiting periods.

The range of blue light in the ordinary LED spectrum is relatively large, and excessive blue light and improper use of lighting fixtures can cause visual damage. Blue light inhibits the secretion of melatonin, which may cause insomnia.

Application of full spectrum lamps

Plant lighting

The effect of spectral range on plants:

The wavelength of 280-315nm is already ultraviolet light, which has the function of directly suppressing the growth of various animals, plants and even fungi; 315-400nm light wave is also a far ultraviolet light, which absorbs less chlorophyll and prevents stem elongation; 400-520nm( Blue) wavelength can directly develop plant roots and stems, and has the largest absorption ratio of chlorophyll and carotenoids, and has the greatest impact on photosynthesis; 520-610nm (green) green pigment has a low absorption rate; 610~720nm (red) It has a significant impact on photosynthesis and plant growth; wavelengths of 720~1000nm are generally infrared wavelengths, which have low absorption rate for plants and can directly stimulate cell elongation, which will affect flowering and seed germination;> 1000nm -> is close to thunder The wavelength of the emitted light has been converted into heat.

In addition, a small amount of ultraviolet light contained in full-spectrum LEDs can effectively prevent pests and diseases.

Previous plant lights were mostly red and blue, full blue, and full red to cover the wavelength range required for photosynthesis of plants. In recent years, full-spectrum LED plant growth lights have become popular.

Camera full spectrum LED fill light

Basically, the camera will be equipped with LED fill light, which is used for shooting at night and in dark environments. Without this kind of fill light, there will always be problems of whitening, skin tone, and object color completely deviating from the normal color. The full-spectrum fill light can complement all wavelengths and colors, making the skin color and color closer to the real thing.

In addition, full-spectrum LEDs are also used in areas that require high spectral quality, such as surgical lights, eye protection lights, museum lighting, and high-end lighting.
