Abstract

The invention relates to a method for acquiring a uniform area light source, which can acquire the uniform area light source without the need of increasing the original light source power, reduces thesize and lowers the cost. The method for acquiring the uniform area light source comprises the following steps of acquiring the light intensity distribution of each point light source forming the area light source on a region needing to be irradiated by the area light source; acquiring the light intensity at each position on the region needing to be irradiated by the area light source based on the light intensity distribution; determining the light intensity uniformity on the region needing to be irradiated by the area light source according to the light intensity at each position on the region needing to be irradiated by the area light source; determining the light intensity uniformity performance of the area light source based on the determined light intensity uniformity; and optimizingthe light intensity uniformity performance to obtain the optimized power and / or distance of each point light source.

Description

technical field [0001] The present disclosure relates to the field of light sources, and in particular, to a method for obtaining a uniform surface light source. Background technique [0002] At present, the uniform surface light source is usually realized by performing diffuse reflection on the surface or in a special light-guiding material. However, there is a loss of optical power during each diffuse reflection, resulting in the need to increase the power of the original light source, and also increase the size and cost. Contents of the invention [0003] The purpose of the present disclosure is to provide a method for obtaining a uniform surface light source, which can obtain a uniform surface light source without increasing the power of the original light source, and reduces volume and cost. [0004] According to the first embodiment of the present disclosure, a method for obtaining a uniform surface light source is provided, including: obtaining the light intensity ...
