The invention relates to construction, in particular to transformable roofs of buildings, and can be used mainly in areas with harsh climatic conditions, with an extended heating period, as well as in areas with a long polar night.

The purpose of the invention is to increase the efficiency of use of natural light energy while reducing the area, as well as reducing heat loss through the light shaft,

Fig. 1 shows the light shaft with the room apertures extending into it, is blocked by a device for the redistribution of light radiation, a section; Fig. 2 shows possible arrangements for the placement of sources of artificial light.

The energy-efficient lighting system of the building consists of a light shaft 1, into which the light rooms of the 2 interior rooms 3 exit. The entrance opening of the shaft 1 is blocked by a device 4 for redistributing the light radiation consisting of hollow panels 5 with an air gap 6,

On one of the sides of the panels 5, which can be rotated around the horizontal axes 7 by means of a pivoting mechanism 8, a coating 9 is applied, which has a directionally reflecting ability, and the other side 10 of the panels 5 is translucent. An artificial lighting unit operating in conjunction with device A for redistributing light radiation consists of sources 11 of light that can be placed under device 4 for redistributing light radiation and inside light shaft 1. Inside hollow panels 5 can be placed sources 12 of artificial light, and At the open ends of the panels at the points of attachment of the axes of rotation, additional installations of artificial lighting may be located. The artificial light installation 11 is powered through the automatic light flux control device 13.

An energy efficient building lighting system works as follows:

In the daytime, the luminous flux from the sky and the Sun is reflected inside the shaft 1 from the reflective

covering 9 panels 5, rotated with the help of a pivot mechanism 8 to position A around horizontal axes 7 and oriented relative to the Sun (Fig. 1), then penetrates through the light openings 2 into room 3; At night, panels 5 turn around the axes 7 in such a way that the coating 9 forms a continuous reflective surface, and the panels 5 thus constitute a continuous heat shield of the light box 1. When the panels 5 are rotated, the artificial light sources 12 placed inside the hollow cores Neleus 5, the luminous flux which is reflected from the light reflecting coatings 9 and 10 side through the translucent panel 5 gets inside the light shaft 1,

When the panels 5 are rotated to the position B, the light flux from the artificial light installation is reflected from the reflective coating 9 of the panels 5 and falls inside the shaft,

Under polar night conditions, sources of artificial light 11, working in conjunction with the reflective coating 9 of the device 4 for the redistribution of light radiation, are so- give in the light shaft 1 artificial light environment, imitating natural light radiation. A device 13 for automatically controlling the luminous flux, through which artificial light sources 11 are powered, makes it possible to create a dynamic light regime in the light shaft 1, which corresponds to the dynamics of natural lighting that best corresponds to the human biological rhythm.

The use of the invention allows to move to new building construction solutions, namely to the formation of compact residential groups.
