Method and system for estimating landscape lighting source spectrum reflection luminous efficiency

Abstract

The invention relates to a method and system for estimating landscape lighting source spectrum reflection luminous efficiency. The estimating method includes the steps that firstly, a light spectrum of a landscape lighting source is detected, and the luminous efficiency of the lighting source is calculated according to the light spectrum; secondly, lighting targets in a lighting area are classified according to colors, and the proportion of the area, occupied by the lighting targets of the various colors in the lighting area, in the lighting area is calculated; thirdly, a reflection spectrum curve test is conducted on the lighting targets of the various colors in the lighting area, and the spectrum reflection luminous efficiency on the lighting targets of the various colors in the lighting area where the lighting source is located is calculated according to a test result and the luminous efficiency of the lighting source; fourthly, the spectrum reflection luminous efficiency of the lighting area where the lighting source is located is calculated according to the spectrum reflection luminous efficiency on the lighting targets of the various colors in the lighting area where the lighting source is located and with the proportion of the area, occupied by the lighting targets of the various colors, in the lighting area as the weight of the lighting source.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to an evaluation method and evaluation system for spectrum reflection light effect of a landscape lighting light source. Background technique [0002] In functional lighting, people focus on light source efficiency (lm / W), while urban landscape lighting is more inclined to decorative lighting, and its requirements are different from functional lighting. The light source used for functional lighting is white light, which meets the needs of people's daily life such as work and study. etc., in most cases, its color is one or two or three, at least in a relatively small area, its color is relatively single. For landscape lighting, people don't care how bright the light source itself is, but the brightness reflected back after it illuminates the landscape. It is obviously inappropriate to use traditional light effects to evaluate the efficiency of landscape lighting. Contents of th...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a method and evaluation system for evaluating the spectral reflection light effect of a landscape lighting source, which is used to solve the light source light effect evaluation method used in the prior art to directly evaluate the luminous efficiency of a light source, which is not suitable for landscape lighting. The lighting characteristics cannot satisfy the lack of evaluation of landscape lighting efficiency
