SPECTRUM-BASED LIGHT-EMITTING FIXTURE AND SPECTRUM-BASED LIGHT EMISSION METHOD

Abstract: the present invention provides a spectrum-based light-emitting fixture and a spectrum-based light emission method. the spectrum-based light-emitting fixture has light sources with multiple emission peak wavelengths, the spectrum-based light emission method is based on waveband integral calculus, where absorption peaks in a given spectrum that meet energy variation requirements are identified, and their wavelengths are used to divide primary wavebands. each primary waveband is further subdivided into multiple secondary wavebands, and the spectral energy of each secondary waveband is calculated through integration. the selected light sources have emission peak wavelengths that are close to and match the mid-wavelengths of the secondary wavebands. by matching the light sources with the spectral energy of the corresponding secondary wavebands, the adjustment of spectrum-based light emission is achieved, thus, the emission spectrum of the spectrum-based light-emitting fixture can highly restore the given spectrum with high accuracy.
