Abstract

The invention relates to the design of a decorative luminaire, can be used in household lighting engineering in the design of apartment interiors and can enhance the decorative effect of the luminaire. The decorative luminaire consists of a bundle of optical fibers 2 provided with an illuminator 5, a collimating lens 7 and rotating light filters 12. Between the input end 3 of the bundle of optical fibers 2 and a collimating lens 7 a transparent plate 17 is installed with a directionally scattered light transmission. The transparent plate 17 may have a one-sided matting and be installed with a matted surface close to the input end 3 of the light guide bundles 2. This allows to increase the luminescence angles of the output ends 15 of the light guides 2 and thereby increase the decorative effect of the lamp. 1 hp f-ly, 3 ill. (L with O5 00 00 4 (Rag.1

Description

The invention relates to household lighting and can be used to create decorative effects in window dressing, apartment interiors, restaurants, and cinemas.

The purpose of the invention is to enhance the decorative effect of the luminaire by increasing the viewing angle and improving the uniformity of the glow of the output ends of the light guides.

FIG. 1 shows a lamp, a general view, in FIG. Figures 2 and 3 show plate placement options with directionally-diffused transmission.

Decorative lamp contains a bundle of 1 optical fibers 2, bonded10

All the dissipated energy from the plate 17 vanishes, the latter is placed in contact with the output end 3 (Fig. 3).

The lamp works as follows.

From the included source, the 5 direct and reflected rays from the reflector 6 are converted by a collimating lens 7 into a parallel stream of main rays. In front of the input end 3 of the beam 1 of the optical fibers 2, by means of the plate 17, this flux is again transformed into directionally scattered with the scattering angle of the scattering indicatrix close to the calculated aperture angle of the optical fibers.

Thus, the entire entrance aperture of the optical fibers is completely filled with light.

At its exit from the ends of the 15, the light strikes the adhesive, the illuminator with the light source 5, the reflector 6 and the collimating lens 7. The optical axis 8 of the illuminator is aligned with the axis 9 of the bonded end 10 of the beam of 1 optical fibers 2

spans in all directions within the cone 19 and the lamp is visible from any point of the surrounding space.

In addition, if the entire aperture of the optical fibers of the beam is completely filled between the illuminator and the input end 20, a beam 1 with a light filter is placed at the bends of optical fibers (peripheral frames 12, which are installed with the possible optical fibers, are bent more central), for example, from the engine 13, part of the light passing through the cores of rigidly fixed on the wall of the housing 14. Fiber optic fibers 2 due to different lengths in the beam 1 (the length of the central optical fibers is less than the peripheral ones) under the force of gravity occupy ur vnoveshennoe position and their output ends 15 arranged along the shape of the curve poverh25

light guides, goes into the shell, and the light guides light TC lengthwise. The different bends of the light guides allow the light to come out at different distances from the ends, which contributes to the decorative effect of the lamp.

for example, in the form of a spherical surface 16. A transparent plate 17 with directionally-scattered transmission is placed between the input end 3 of the beam 1 and the disk 11 with optical filters 12.

Claims (2)

1. A decorative luminaire containing coaxially mounted illuminator, collimating lens, disk with light filters, equipped with a rotation drive, and continuous directional transmission of 35 optical fibers fastened together. its entrance end facing the illuminator, characterized in that, in order to enhance the decorative effect by increasing the viewing angle and improving, the optical material with enhanced internal light scattering, for example, so-called smoky glass, equally equilibrates. For the proposed luminaire, it is most expedient to use a plate of transparent glass with a high coefficient of directional transmission, one of the surfaces of which, mainly from the input end 3 of the beam 1, is matted. The plate 17 can be located at the luminosity of the output ends of the optical fibers; it is equipped with a transparent plate of directionally diffused transmission, installed between the input end of the optical fiber bundle and the disk with optical filters. 2. The lamp according to claim. 1, which is different. from the input end 3 (Fig. 2), but in this r by the fact that the transparent plate is made In this case, a part of the scattered flux, (for example, beam 18), does not fall on the input end of beam 3 1. For more efficient use of one-sided matting and set the matted surface in contact with the input end of the optical fiber bundle. All the dissipated energy from the plate 17 vanishes, the latter is placed in contact with the output end 3 (Fig. 3). The lamp works as follows. From the included source, the 5 direct and reflected rays from the reflector 6 are converted by a collimating lens 7 into a parallel stream of main rays. In front of the input end 3 of the beam 1 of the optical fibers 2, by means of the plate 17, this flux is again transformed into directionally scattered with the scattering angle of the scattering indicatrix close to the calculated aperture angle of the optical fibers. Thus, the entire entrance aperture of the optical fibers is completely filled with light. light is the whole aperture of the optical fibers of the beam, then at the bending of the optical fibers (peripheral optical fibers are bent more central) part of the light passing through the cores light guides, goes into the shell, and the light guides light TC lengthwise. The different bends of the light guides allow the light to come out at different distances from the ends, which contributes to the decorative effect of the lamp. thirty Invention Formula The luminescence of the output ends of the optical fibers is provided with a transparent plate of directionally diffused transmission, installed between the input end of the fiber bundle and the disk with light filters. 2. The lamp according to claim. 1, which is different.  d that transparent plate is made unilaterally frosted and installed frosted surface in contact with the input end of the bundle of optical fibers. 1b  // / / / U / / // (Reg. 2 J FIG. 3
