Description

Technical Field

[0001] The utility model relates to the field of lighting, in particular to a spectral luminaire. 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 increasing.

[0003] Full-spectrum lighting is the goal that LED lighting is currently approaching based on the demand for healthy lighting. As the name suggests, full-spectrum lighting is a lighting method that contains all visible light, ultraviolet light, and infrared light in the spectrum. Its biggest feature is that it approaches the characteristics of the natural spectrum. Compared with traditional LED lighting, full-spectrum lighting is closer to the color balance of sunlight, and can provide more realistic and natural visual lighting effects and healthy non-visual lighting. This lighting method has a positive impact on people's visual health, physiological health, and comfort, and also helps to improve work efficiency and reduce fatigue. Full-spectrum lighting has a wide range of applications, including but not limited to medical, education, entertainment, and construction. At the same time, with the continuous development of science and technology and the continuous improvement of people's awareness of health and environmental protection, the application scope of full-spectrum lighting will be further expanded. For example, with the continuous development of artificial intelligence technology, the intelligent control of full-spectrum lighting will also become an important development direction in the future.

[0004] In short, full-spectrum lighting is the current development direction of LED lighting, which has broad application prospects and important social significance. However, as far as the current development status of full-spectrum lighting is concerned, on the one hand, the current full-spectrum lighting fixtures have a single luminous spectrum and cannot simulate the natural changes of sunlight with time, geographical coordinates, weather, environment and other factors, so long-term use may cause physiological disorders in the human body; on the other hand, the current full-spectrum lighting fixtures have a low degree of restoration of the solar spectrum. Figure 1 As shown in the figure, the normalized relative spectrum of the full-spectrum lighting fixtures currently on the market after normalization with the sunlight spectrum is shown. It can be seen from the reference figure that the spectrum of the full-spectrum lighting fixtures currently on the market has one or more large gaps and peaks in the blue light part, resulting in it not being consistent with the real sunlight spectrum. In other words, the lighting effect of the full-spectrum lighting fixtures currently on the market is still not comparable to sunlight. Utility Model Content

[0038] Specifically, the spectral luminaire has a plurality of light sources, and in a state where each light source has at least one corresponding emission peak wavelength, the light source of the spectral luminaire has a plurality of emission peak wavelengths, and each of the light sources has a single corresponding emission peak wavelength band B. m The spectrum luminescence method is based on the idea of ​​band calculus, and according to the identification of absorption peaks that meet certain energy change requirements in the spectrum, at least two emission peak bands B are selected with the wavelength of the absorption peak as the boundary within the band range of 300nm-500nm. m , where each emission peak band B m The starting wavelength is λ mS , the end wavelength is λ mE , wherein at least one of the emission peak bands B m The half-wave width (λ mE ﹣λ mS ) / 2≥14nm, corresponding to the emission peak band B with a half-wave width greater than or equal to 14nm m The half-wave emission peak band B m , wherein the emission peak band B has a half-wave width less than 14 nm m There is at least one emission peak band B m The emission peak wavelength is greater than or equal to the wide half-wave emission peak band B m The emission peak wavelength is that there is at least one emission peak band B with a half-wave width less than 14 nm. m The median wavelength is greater than or equal to the wide half-wave emission peak band B m The wavelength median value, wherein the spectral luminaire has a wavelength that satisfies each of the emission peak bands B m The light source of the spectral luminaire has a wavelength corresponding to the emission peak band B. m The half-wave width and the emission peak wavelength are close, so that based on at least one of the emission peak wavelength bands B m The wide half-wave setting improves the continuity of the spectrum and can effectively reduce the gaps and peaks in the spectrum to make up for the defects of the spectrum of existing full-spectrum lighting fixtures, so that the luminous spectrum of the corresponding spectrum-emitting lamps can highly restore the sunlight spectrum.

[0047] The spectral luminaire has a plurality of light sources, each of which has at least one corresponding emission peak wavelength. The light sources of the spectral luminaire have a plurality of emission peak wavelengths, wherein the light sources are connected to the corresponding emission peak wavelength bands B by the following steps: m Matches:

[0048] Integrate to obtain the corresponding emission peak band B in a spectrum m The spectral energy E m ;and

[0049] The corresponding emission peak band B mThe radiant flux of the light source and the spectral energy E corresponding to the emission peak band m Matching so that the combined spectrum of each of the light sources matches the spectrum.
