Recently there is growing interest to impart individuality and create comfort in premises by wall painting. Proceeding from such the need, we are designing an amateur portable projection device that will allow drawing an image of any complexity on the walls to any person, even if he has absolutely no experience in this matter. The features of the developed device in comparison with the existing projection systems are as follows: 1) a small size (a high degree of compactness); 2) the ease-to-use device; 3) a low cost of the device. Such a compact and relatively inexpensive projection-illumination device will occupy one of the important niches in the design field. In the article several known variants of the structural schemes of the projection device are considered. We propose our own solutions to the functional problem, based on the terms of the technical assignment. Also, the choice of the radiation source is explained and an approximate overall calculation of the lighting part is made with subsequent conclusions. The research of the developed amateur portable projection device application in various types of premises and at various illuminations is carried out. In addition, in the article a possibility of modeling and calculating the illumination of the transparent object by using of various CAE software is considered.
