Due to the significant impact of lighting environment on human health, photohealth, as an innovative field in the big health industry, is becoming increasingly prominent and has become a global emerging market. Light health products have gradually been applied to various sectors such as lighting, healthcare, medical care, and services. Among them, advocating for “healthy lighting” to improve light quality and comfort has significant practical significance, with a market size exceeding one trillion yuan.
Full spectrum refers to simulating the spectrum of natural light (with the same color temperature) and removing harmful ultraviolet and infrared rays from natural light. Compared with natural light, the integrity of the full spectrum is close to the similarity of the natural light spectrum. Full spectrum LED reduces the blue light peak compared to ordinary LED, improves the continuity of the visible light band, and effectively enhances the quality of LED lighting. The core theory of light health is that “sunlight is the healthiest light”, and its three core technologies are the effective combination of light code, light formula, and light control, which enables the display of advantages such as color saturation, color reproduction, and low blue light in lighting scenes. Based on these advantages, full spectrum LED is undoubtedly the most suitable artificial light source for “light health” needs at present.
More importantly, light health can also redefine full spectrum lighting. Although the full spectrum we are currently discussing in the field of LED lighting mainly refers to the full spectrum of visible light, which means that the proportion of each wavelength component in the visible light is similar to that of sunlight, and the color rendering index of illumination light is close to that of sunlight. With the continuous development of technology and market demand, the future development direction of full spectrum LED is inevitably to align with sunlight, including the combination of invisible light spectra. It can not only be applied in lighting, but also in the field of light health, and can be widely used in fields such as light health and light medicine.

Full spectrum LED lights are more suitable for scenes that require accurate color representation. Compared to ordinary LEDs, full spectrum LEDs have a wider range of application prospects. In addition to being used in educational lighting, eye protection table lamps, and home lighting, they can also be applied in fields that require high spectral quality, such as surgical lights, eye protection lights, museum lighting, and high-end venue lighting. However, after years of market cultivation, many companies have ventured into full spectrum health lighting, but the market popularity of full spectrum lighting is still not high, and promotion is still difficult. Why?
On the one hand, full spectrum technology is the main application technology for health lighting, and many companies regard it as a “BMW”. Its price is not affordable and it is difficult for most consumers to accept. Especially, the current lighting market has uneven product quality and diverse prices, making it difficult for consumers to distinguish and easily influenced by prices. On the other hand, the development of the healthy lighting industry has been slow, and the industry promoted in the market is still immature.
At present, full spectrum LED is still in the emerging stage, as its cost is temporarily higher than ordinary LED, and due to price constraints, the market share of full spectrum LED in the lighting market is very small. But with the improvement of technology and the popularization of health lighting awareness, it is believed that more users will recognize the importance of the light quality of full spectrum lighting products, and their market share will grow rapidly. Moreover, the lighting scheme combining full spectrum LED with intelligent control can be better applied in various scenarios, fully leveraging the advantages of full spectrum LED in improving lighting quality and enhancing people’s recognition of light comfort.
