Description

Location lamp
Object of the invention. The subject of the invention is a location lamp preferably for installing to vertical walls and columns.
Technical field. There are known solutions used in location lamps based on traditional light sources like incandescent or fluorescent lamps. Such location lamps are characterized by significant depth and large power consumption. There are known location lamps that use LED elements as well. Most of them have LED elements placed in front of light diffusing element, and resulting effect is characteristics of the fact that separate light points of LED elements are visible.
Aspect of the invention. The essence of the invention consists in the fact that on the surface of the location lamp, is placed flat optical element of a designed outer shape equipped with a surface which reflects light rays, powered by visible light through a transparent outer edge equipped with light diffusion elements and generated preferably by multiple LED elements placed perpendicularly or at a designed angle with respect of a main axis of the location lamp. Flat optical element is made preferably of transparent plastic or transparent glass, and at the same time the surface is transparent or is equipped with matt surface structure of a designed gradation for light scattering.
Flat optical element is equipped with the cone shape surface, formed at a designed angle which reflects light rays emitted by multiple LED elements. Transparent outer edge is equipped with light scattering elements formed together with flat optical element.
Outer face of the surface are formed multiple convex lamellae, and are placed concentrically with respect to the main axis, and at the same time height of the single lamellae is equal or different.
Outer face of the surface of the flat optical element, light reflecting layer is placed.
Light reflecting layer is made as thin layer with matt face put on lamellae, or thin mirror face put on the surface of the flat optical element.
Beneficial effects resulting from the use of the aspect of the invention. The use of LED elements results in lowering power consumption as well as elongation of working time up to
100.000 hours, which in practice makes such device maintenance-free. New flat optical element used in the location lamp results in very good light diffusion and single LED elements are not visible.
Description of the drawing figures. The subject of the invention is shown schematically in examples of use in the drawing, where fig.1 - shows schematically in a cross section the location lamp equipped with the fiat optical element and powered by LED elements, fig.2 - shows schematically in a cross section flat optical element with visible LED elements and light rays reflecting lamellae, fig.3 - shows schematically the flat optical element with visible light rays reflecting lamellae arrangement and surface on which surface structure is put on, fιg.4 - shows schematically in a top view the flat optical element equipped with LED elements distributed all around, fig.5 - shows schematically in a top view the flat optical element equipped with LED elements distributed all around, in which light scattering elements of different parameters and lamellae of non-uniform distribution is used, fig.6 - shows schematically different flat optical element outer shapes. The subject of the invention is shown schematically in examples of use in the drawings from fig.l to fιg.6, where fig.l shows schematically the location lamp with all the details concerning its structure and the essence of the invention.
The drawings from fig.l to fιg.6 show the location lamp elements and its position in the location lamp: location lamp 1, flat optical element 2, outer shape 3, light rays 4, transparent outer edge 5, LED elements 6, main axis 7, surface structure 8, lamellae 9, light reflecting layer 10, light scattering element 1_1 , surface A, surface B, surface C, angle D, angle E. The operation of the location lamp is as follows: having on the location lamp, the LED elements 6 generate light rays 4, which are directed by scattering element 1_1 , placed at the outer edge 5 of the flat optical element 2, then light rays 4 are directed to the convex lamellae 9, which have light reflecting layer 10, and light reflection and scattering of the light rays 4 towards the surface B equipped with surface structure 8 or matt surface is done at the lamellae surface 9.
With respect to unparalleled properties, that is operation time of 100.000 hours, very small power consumption that is approximately 1 Watt and low maintenance cost, the location lamp created according to the aspect of the invention can be used for instance in public buildings. Location lamps can be used in apartment houses where as markers for stairs, corridors, lifts and other appliances whose position should be marked.
