Description
Technical Field
[0001] The utility model relates to the field of lighting, in particular to a spectrum lighting lamp. Background Art
[0002] With the continuous development of LED lighting technology, lighting should not only be energy-efficient, but also healthy and comfortable light color quality is attracting more and more attention. With the continuous emergence of new technologies, people have put forward higher requirements for lighting quality and comfort, especially the requirements for healthy lighting are constantly improving. Healthy and comfortable high-quality lighting is attracting more and more attention. It should not only meet the needs of perfect visual lighting, but also take into account people's health needs. Among them, the blue-violet light band from 400nm to 490nm is the key spectral range that affects human biorhythms.
[0003] Natural sunlight has a positive impact on people's visual health, physiological health and comfort. It also helps to improve work efficiency and reduce fatigue. During the sunlight period of a day, the color temperature is above 5000K for about 60%-70% of the time, and the color temperature is above 4000K for about 85%-90% of the time. The sunlight in these time periods is very rich in blue and purple light, which not only affects human biological rhythms, but also has a very important positive effect on the emmetropia development of the eyeball.
[0004] However, in recent years, due to the popularity of electronic screens, electronic screens will generate blue light radiation. Blue light can penetrate the eyeball and reach the retina directly. Excessive exposure to blue light may accelerate the damage of retinal cells. Long-term exposure to high-intensity blue light will cause damage to the retina. Therefore, in recent years, the concept of blue light protection has been deeply rooted in people's minds, leading to people's excessive and one-sided pursuit of less blue light and blue light protection, ignoring the positive effects of the above-mentioned blue-violet light on people's health, but causing negative effects on health. The concept of blue light protection is not only related to electronic screens. People have also begun to one-sidedly pursue less blue light and blue light protection in lamps. The spectrum of full-spectrum lighting fixtures on the market currently has one or more large gaps in the blue light part, such as Figure 1 As shown in the figure, the normalized relative spectrum of a full-spectrum lamp with a color temperature of 5000K on the market after normalization with the sunlight spectrum with a color temperature of 5000K is shown. Its spectrum in the 460nm-480nm band is seriously lacking, resulting in it being inconsistent with the real sunlight spectrum. In other words, this type of lamp cannot accurately simulate sunlight, and its actual lighting effect cannot be compared with sunlight, and may cause physiological disorders to the human body due to long-term use.
