Popis: In order to allow people to have a good visual environment,also to make better use of light,it is important that to design a kind of reflectors for LED based on uniform illumination.Light sources is put in spherical annular array to avoid the vertigo,owing to excessive light intensity,that is produced if light source vertical illumination;but also to expand the scope of the lighting.This kind of reflectors is made up of free-form points that are obtained by distribution using grid method.Then the solid model is set up using mechanical modeling software and another then use the optical simulation software to carry out the illumination.The results illustrate that the free-form reflector can make a better use of light energy than the old one.Uniformity is greatly improved.
