Embodiment 1

[0024] In this embodiment, the color of the object to be illuminated is relatively uniform and single. The method for designing the spectrum of the energy-saving lighting source for the object to be illuminated is as follows:

[0025] (1) Obtain spectral reflection characteristics: Since the color of the object to be illuminated is relatively uniform, the object to be illuminated is regarded as a whole, and its surface reflection characteristic R is tested with a continuously adjustable laser light source. i (λ), i=1, the measured object surface reflection characteristics are as follows figure 1 shown.

[0026] (2) Establish optimization objectives and constraints:

[0027] 2.1) Minimum target optimization: take the object to be illuminated as a secondary light source, and calculate the ratio between the optical power consumption of the designed light source S1 and the optical power consumption of the reference white light source S2 under the condition of generating the same ...

Abstract

The invention provides a design method of an energy-saving lighting source spectrum and aims at solving the problem of energy waste due to that an invalid spectrum of an existing lighting source is absorbed by an object in the prior art. The design method comprises the following steps: (1) obtaining spectral reflection properties; (2) establishing an optimization goal and a constraint condition; (3) solving a genetic algorithm; and (4) further obtaining a group of spectral data lowest in energy consumption according to a chromosome lowest in fitness obtained in the previous step, wherein the data is the energy-saving lighting source spectrum of an object to be lighted. In the design method, firstly, the spectral reflection properties of the surface of the object to be lighted are obtained, and secondly, the light source spectrum is optimized by use of the genetic algorithm under the condition of ensuring that the chromatic aberration between the designed light source and a white light source is smaller than values within a human eye perceptible range; as a result, the portion, absorbed by the object, of the spectrum is reduced, the utilization rate of the spectrum and the energy utilization rate are increased, and the purposes of saving energy and lighting are achieved. The design method of the energy-saving lighting source spectrum is applicable to lighting such as display lighting and furniture lighting in buildings.

Description

technical field [0001] The invention relates to an energy-saving lighting source, in particular to an energy-saving lighting source spectrum design method. Background technique [0002] At present, the energy consumption generated by electric light source lighting occupies a large proportion in the total energy consumption of electric power. In general lighting and exhibition lighting, white light sources with better color rendering quality are generally used, and the spectral power distribution of this light source in the visible light band is relatively uniform. The surface color of an object that the human eye can perceive is determined by the spectrum of the light source and the spectral reflection characteristics of the surface of the illuminated object. Only when the spectral energy reflected by the surface of the object enters the human eye can it be perceived by humans; the spectral energy of the light source absorbed by the object is transformed into The thermal en...
