The convex lenses 43 and 44 are provided in front of and behind the mirror 42 on the T-shaped tube 41. The front convex lens 43 is the same size as the diameter and the focus is in the hole 42a of the mirror 42. The rear convex lens 44 has a size similar to that of the hole 42a of the mirror 42.

Accordingly, the light rays entering the front opening 41a pass through the hole 42a of the mirror 42 and are sent to the rear opening 41b, and the exaggeration entering the fitting opening 41c is reflected from the mirror 42, and the rear opening ( 41b). Therefore, in the rear opening 41b, all the light rays passing through the light collecting plates 20 are focused on each reflecting plate 11.

Although not shown in the drawing, the means for focusing the light beam may be implemented in various ways depending on the installation location. For example, the cylinder can be reflected in the required direction by using a mirror divided into four in the center direction.

In the main body 10, the connecting portion between the main duct 30 and the duct 33 and the connecting portion between the duct 33 and 34 are provided with mirrors, respectively, to reflect light at 90 degrees.

In any of the above-described parts, it is possible to focus and transmit sunlight without using the conventional optical cable. For example, assuming that a solar lighting device is installed in 63 building, the conventional device is installed on the roof and draws optical fiber to the required place, but the device of the present invention is attached to the wall and directly scans where it is needed. Can transmit light.

Even when comparing the amount of sunlight, it is much more advantageous to install on the south wall than on the roof. It can collect 90,000 lumens of light when the direct illuminance on a sunny day exceeds 100,000 lx and deliver 63,000 lumens of light at 70% efficiency to 700 lux in a 9m × 10m room. lx) illuminance is maintained.

As described above, the lighting apparatus of the present invention can contribute to saving the electric energy for lighting and reducing the environmental pollution, which occupies about one third of the total electric energy consumption of the building according to the method of concentrating and distributing the sunlight to the required place in the building.
