Device and method for detecting light condensation efficiency of condensing lens

Abstract

The invention discloses a device and method for detecting the light condensation efficiency of a condensing lens. The method comprises the following steps: firstly, arranging a stable flat light source which emits light uniformly at one opening of a black box, and arranging a condensing lens under detection at the other opening of the black box; secondly, arranging a light sensor at the focus of the condensing lens under detection and the position of the condensing lens under detection in sequence; thirdly, recording the energy of the incident light measured by the light sensor and condensed by the condensing lens under detection and the irradiation energy of the flat light source at the position of the condensing lens under detection; fourthly, measuring the light receiving area of the condensing lens under detection and the light sensing area of the light sensor; and finally, calculating the light condensation efficiency of the condensing lens under detection by multiplying the ratio of the energy of the incident light condensed by the condensing lens under detection to the irradiation energy of the flat light source at the position of the condensing lens under detection by the ratio of the light sensing area of the light sensor to the light receiving area of the condensing lens under detection. Accordingly, the device and method for detecting the light condensation efficiency of the condensing lens can be used for detecting more stable light condensation efficiency of the condensing lens, which is more approximate to the light condensation efficiency of the condensing lens actually irradiated by sunlight.

Description

technical field [0001] The invention relates to the technical field of condenser mirrors, in particular to a detection device and method for light collection efficiency of a condenser mirror. Background technique [0002] With the improvement of living standards and the increase of population, human beings' demand and consumption of energy are increasing day by day. However, most of the way to generate energy now comes from thermal energy conversion of burning petrochemical raw materials, such as coal and oil used in power generation. As well as the diesel and gasoline used in the movement of automobiles and motorcycles, a large amount of carbon dioxide is produced as a result. When the carbon dioxide produced by human activities exceeds the self-cleaning capacity of nature, the gradual increase in carbon dioxide in the atmosphere has already formed the greenhouse effect, which in turn will lead to the warming of the earth's surface, accompanied by environmental changes such...

In short, even if a point light source with the same radiation energy in each direction angle is used, when a parallel beam is generated through an optical lens, the light energy distribution of each part of the parallel beam is not uniform, that is, the energy distribution of the parallel beam irradiating the condenser lens to be tested is Inhomogeneous, which is very different from the actual sunlight that is uniformly illuminated, resulting in a large gap between the light collection efficiency of the condenser lens measured using the above detection framework and when using real sunlight
