Description

Modular lighting fixture using flat light sources

Technical field

The described solution of luminaire design is based on the use of surface directional light sources, which provide an optional combination of direct and indirect light component with the possibility of extension by color solutions based on RGB technology.

BACKGROUND OF THE INVENTION

Previous solutions of luminaires using surface light sources (usually based on the use of LED technology) use only the part of the half-space into which the light is emitted by the light sources. This solution has the disadvantage of spaces where luminaires using an indirect light component are also suitable.

The essence of the technical solution

The proposed solution overcomes the above-mentioned disadvantages of using surface light sources such that the luminaire is comprised of at least one light source in each half-space, thereby ensuring a more even light distribution in the emitted directions. For various lighting scenes, it is possible to switch on, off or dim individual components of the luminaire, thus changing the ratio between direct and indirect light component.

Exemplary embodiments of the technical solution

The modular luminaire with the planar light sources is shown in Figure 1. The luminaire is composed of more than two planar directional light sources (luminous flux indicated by arrows) so that the planar sources 1 for the direct light component shine downward from the plane of the luminaire, planar sources 2 the lights for the indirect component of the light shine upwards from the plane of the luminaire.

The cross-section of the surface luminaire is shown in Figure 2. This variant of the luminaire is possible to mount on a ceiling or wall, and the individual modules can be mounted on a mounting base 3, on which are mounted flat light modules 1 for direct light and a sheet source 2 for the indirect light component. The individual components may be spatially positioned in a single plane or in several planes. Possibility of mounting individual modules in different luminaires in one plane - scheme 2a, or in different planes - scheme 2b.

Figure 3 shows an example of use for pendant luminaires. The individual light sources 1 for the direct light component and the light sources 2 for the indirect light component are assembled in this type of luminaire to form a complete luminaire that is suspended on the ropes 4 anchored in the ceiling box 5 or directly in the ceiling. Alternatively, a combination of planar light sources is shown in one plane - scheme 3a, or in different planes - scheme 3b.

Figure 4 shows a variant using sheets of transparent or translucent material 6 where the lateral or frontal illumination of a glass or polymer-based material accentuates the direct or indirect component of light and rupture the resulting luminaire design.

Figure 5 schematically shows shape variants of luminaires using basic geometric shapes.

Industrial applicability

Modular lighting fixtures using flat light sources for direct and indirect light components are industrially applicable for commercial and residential interior lighting.
