Description

Technical Field

[0001] The utility model relates to the technical field of multi-spectrum LED flat panel large row of lights, in particular to a multi-spectrum LED flat panel large row of lights. Background Art

[0002] LED, or light emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. LED can directly emit red, yellow, blue, green, cyan, orange, purple, and white light. It has the advantages of small size, fast response speed, long life, high reliability, low power consumption, etc., and can operate under low voltage and low current conditions.

[0003] Different from general light sources, LED can only produce specific wavelengths. Light stimulates organisms to affect the body, that is, the biological effect of light. LED light of different wavelengths produces different biological effects, and light of different wavelengths has different colors. Light of different colors has different biological effects on the human body. For example, red light has a wavelength of 600-700nm, has strong penetration, and a penetration depth of 2-5cm. It has a warming effect on the skin and mucous membranes, thereby accelerating the blood motive force, dilating the blood vessels in the deep tissues, reducing blood viscosity and blood lipids, and enhancing the vitality of human cells, thereby reducing swelling, inflammation, analgesia, and accelerating wound healing. Blue light has a wavelength of 425-475nm. When LED blue light irradiates acne on the skin, it can cause chemical changes in the endogenous porphyrins of anaerobic Propionibacterium acnes to produce singlet oxygen, thereby killing bacteria, thereby achieving the effect of eliminating acne and restoring the skin. Therefore, in the field of beauty, it is common to use LED lights for skin care. Commonly used ones are 630nm red light, 430nm blue light, 590nm yellow light, and 830nm infrared light.

[0004] In actual use, the LED on the beauty lamp only has four types of light, which is difficult to meet the spectrum requirements for beauty.
