Description

Light control method and system Technical Field The invention relates to the technical field of light control, in particular to a light control method. Background The usefulness of light illumination is wide, particularly in stage applications. The lamplight can shape various atmospheres, and the good lamplight atmosphere plays roles in rendering and setting off scenes, so that the lamplight of spectators is attracted, and resonance is generated. In order to meet the diversity of the light, different combined effects need to be formed. The high-quality stage lamplight needs effective combination of various lamplights such as power, types, effects and the like, and the optimal effect of the lamplight can be achieved through precise program collocation control. The good stage light energy can show the scene expected to be built on the stage without any surplus. The light effect of the five-light decade is matched with the color, and the light effect of the machine equipment such as a beam lamp, a head shaking lamp, a laser lamp and the like is used for tone, so that a static situation or a dynamic situation is generated. Different atmospheres exhibited by different designs can more fully exhibit the beauty of the stage. However, these lights have exceeded traditional lighting applications, and the more flexible the effect, the larger the applicable scene, often accompanied by the use of high power lights. The high-power output lamplight can generate high-intensity light which is easy to burn when irradiated to human body, and can easily cause damage to eyes in a short time if irradiated to human eyes, and even if irradiated to the surface of an object, the surface of the object can be heated, so that inflammable fire can be seriously caused. In the process of combining the lamplight, a laser light source is usually combined besides high-power lamplight. Whether it is a high power light source or a laser source, high power illumination is unavoidable in order to be effective in large stage. In order to ensure the safety of people and objects in the lamplight action area so as to eliminate the potential safety hazard, the lamplight needs to be reasonably managed. Although the prior art has similar safety protection, the prior art is generally complex in calculation and low in response speed.

After marking the boundary line of the light spot, the method further comprises the steps of obtaining the theoretical shape of the light spot according to the beam shape of the light source of the lamplight and the shape of the shading component on the light path, correcting the boundary line according to the theoretical shape, and eliminating the irregular part and/or the shaded part in the boundary line.
