Illumination layout simulation method and system

Abstract

The invention relates to illumination layout simulation method and system. The prior art has no simulation design method and system for an illumination system. Accordingly, the illumination layout simulation method comprises the following steps of: 1, drawing a three-dimensional model for each electric light source, at least for the luminescence part of each electric light source; 2, setting uniform and dense points on the surface of the luminescence part of each three-dimensional model, and setting radials outwards from each point along a normal direction, wherein a light ray model of the electric light source is formed by all the radials; and 3, intercepting a corresponding section on the corresponding position of the light ray model according to the shape of a surface (which is not limited to be plane) to be illuminated and a relative position between the surface to be illuminated and the electric light source, wherein a cutoff point is formed on the section by each intercepted radial, and the shape and the position of the section correspond to the surface to be illuminated. The invention can provide real-time, cheap and accurate guidance for illumination designs and is suitable for various lamp enterprises and design and production units of the illumination systems.

Description

technical field [0001] The invention relates to a simulation system, in particular to a lighting layout simulation method and system. Background technique [0002] When people carry out the overall design of the lighting system, they simply regard traditional electric light sources such as incandescent lamps, mercury lamps, sodium lamps, and metal halide lamps as point light sources or line light sources. They are all used in occasions where light distribution requirements are not high. [0003] With the continuous improvement of people's awareness of environmental protection and energy saving, people put forward higher requirements for control design. Take street lights as an example: In the past, people only required street lights to be bright enough, and often used words such as "bright lights, like daytime" to describe the bustling scene of the city; It will also cause light pollution; if the irradiation intensity is small, passers-by will not be able to see the road c...

Problems solved by technology

These new electric light sources have many shapes and specificities, and can no longer be simply regarded as point light sources or line light sources. When designing a lighting system, how to combine these new electric light sources with different shapes is very difficult. It is more difficult to design reflective parts (such as reflectors) or refractive parts (such as refractive lenses) for light sources. It often requires multiple trial production experiments and consumes a lot of money to finally finalize the shape, which seriously hinders the application and promotion of new light sources.
