Definitions
- the invention relates to a lens for lighting and an associated lamp.
- optics In order to achieve illumination with a predetermined radiation characteristic, it has hitherto been necessary to use complicated optics.
- such optics consisted of numerous individual components such as reflectors, sliders, diaphragms, lenses, etc.
- Such optics is very complex in terms of the number of components.
- the individual components must be arranged in a defined position to each other in order to obtain a functioning light.
- German Utility Model DE 20 2013 103 270 Ui shows a luminaire with a prismatic structure element.
- the luminaire consists of a light source for generating the light, a reflector for influencing the light and a refractive element for further influencing the light. All of these components must be arranged in a defined position to each other in order to achieve a functioning light with the desired radiation characteristics.
- the invention is therefore based on the object, an optics and an associated lamp, which includes the optics to provide, which allows for low production costs, an exact adjustability of the emission characteristics.
- An optical system according to the invention includes a refractive optical waveguide which includes a light-receiving surface and a light-emitting surface.
- the light-receiving surface is designed to receive light emitted by a light source into the refractive light guide body.
- the light emission surface is designed to emit light guided in the refractive optical waveguide in a radiation characteristic predefined solely by a geometry of the refractive optical waveguide to form a surface which is substantially sharply illuminated by the radiated light.
- the emission characteristic is advantageously the geometric shape of the area illuminated by the emitted light that is substantially sharply delimited.
- the optics consist solely of the refractive Lichtleit emotions.
- a particularly simple production of the optics can be ensured.
- the refractive Lichtleitmaschine is made in one piece. This further reduces the production cost.
- the light receiving surface is a concave recess of the refractive Lichtleit stresses. This ensures a particularly efficient absorption of the light emitted by the light source into the light guide body.
- the light-receiving surface is an at least partially spherical recess of the refractive optical waveguide. A further increase in the efficiency of the absorption of light into the light guide is achieved.
- the light-emitting surface has a recess in a central region opposite to the light-receiving surface.
- a uniform illumination of the area directly below the central area is achieved.
- each point of the light emitting surface has an inclination which adjusts the radiation characteristic. This makes it possible to set the light emission characteristic very precisely.
- the predefined radiation characteristic is a triangular emission characteristic.
- the light-emitting surface then has three at least partially spherical regions.
- the predefined radiation characteristic is a quadrangular, in particular a square or rectangular emission characteristic.
- the light-emitting surface in this case has four at least partially spherical regions.
- the predefined radiation characteristic is a pentagonal radiation characteristic.
- the light-emitting surface in this case has five partially spherical areas.
- the predefined radiation characteristic is a hexagonal radiation characteristic.
- the light-emitting surface then has six at least partially spherical regions.
- the predefined radiation characteristic is a N-angular radiation characteristic.
- the light emitting surface points N at least partially spherical areas.
- the emission characteristics can be set very flexible.
- the partially spherical areas of the light emitting surface are interconnected by transition areas.
- the transition areas have no points of discontinuity of the light emitting surface. This makes it possible to achieve a particularly simple production of the refractive optical waveguide. At the same time a uniform illumination is ensured with the selected radiation characteristic.
- the refractive optical waveguide is mirror-symmetrical with respect to at least one surface through a center of the light-receiving surface. A particularly uniform illumination and a simple production of the light guide are achieved.
- the refractive optical waveguide is rotationally symmetrical with respect to at least one straight through a center of the light receiving surface.
- a particularly uniform illumination is achieved, in particular with a round radiation characteristic.
- the light-emitting surface of the light-receiving surface is at least partially opposed. This ensures a particularly efficient light pipe.
- a compensating surface is tilted by the light-receiving surface with respect to a compensating surface through the light-emitting surface. So it is particularly easy to emit light sideways against the bulb.
- the optics is designed to radiate light irradiated into the light-receiving surface through the illuminant in an irradiation direction through the light-emitting surface in a radiation direction.
- the direction of irradiation and the emission direction are around at least 30 °, preferably tilted by at least 45 °, more preferably by at least 90 ° to each other. This makes it particularly easy to emit light laterally relative to the bulb.
- a compensating surface extends through the light-receiving surface parallel to a compensating surface through the light-emitting surface.
- a luminaire according to the invention includes a previously illustrated optics and a light source.
- the luminous means is attached to the light-receiving surface and configured to radiate light through the light-receiving surface in the refractive Lichtleit emotions. This achieves a luminaire which is particularly easy to produce.
- the lighting means is an LED or OLED or an incandescent lamp or a gas discharge lamp. A particularly simple production of the lamp is achieved.
- the luminaire has no further light-generating and light-conducting elements in addition to the luminous means and the optics. A particularly simple production of the lamp is achieved.
- FIG. 1 shows a first embodiment of the luminaire and optics according to the invention in a three-dimensional view
- FIG. 2 shows a second embodiment of the optics according to the invention in a three-dimensional view
- FIG. Fig. 3 shows a third embodiment of the optical system according to the invention in a lateral sectional view
- FIG. 4 shows a fourth exemplary embodiment of the optics according to the invention in a three-dimensional sectional representation

- Fig. 7 illuminance profiles of various embodiments of the lamp according to the invention.
- Fig. 8 shows an intensity distribution of an embodiment of the luminaire according to the invention.
- the light 10 includes a light source 4, here for example an LED and an optic 1.
- the optics 1 includes a refractive Lichtleitmaschine 6.
- the refractive Lichtleitsammlung 6 includes a light receiving surface 2 and a light emitting surface 3. Die
- the light-receiving surface 2 is arranged opposite to the light-emitting means 4 such that light emitted by the light-emitting means 4 is guided through the light-receiving surface 2 into the interior of the refractive optical waveguide 6.
- the light-receiving surface is a recess of the refractive optical waveguide 6. In particular, it is designed concave. In a particularly advantageous embodiment, it may be spherical or semi-spherical.
- the light-emitting surface 3 is arranged substantially opposite to the light-receiving surface 2.
- the desired radiation characteristic is set.
- a rectangular emission characteristic is desired.
- the refractive optical waveguide 6 is thus embodied such that the light emitting surface 3 has four at least partially spherical regions 11-14, which correspond to the four corners of the rectangular radiation characteristic.
- the at least partially spherical areas are connected to each other by transition areas, so that a soft transition is formed. In particular, no discontinuities of the surface arise.
- FIG. 2 a further embodiment of the optical system 1 according to the invention is shown.
- the bottom which is hidden in Fig. 1, shown.
- a recess 5 which is opposite in a central region of the light receiving surface 2. This recess 5 ensures a particularly uniform illumination in a central region of the emission characteristic.
- Fig. 3 is a sectional view of another embodiment of the optical system 1 according to the invention is shown.
- the cut is made through a center of the light-receiving surface.
- the refractive optical waveguide 6 in this case is mirror-symmetrical with respect to a plane perpendicular is to the cutting plane.
- the recess 5 is arranged directly below the center of the light receiving surface 2.
- FIG. 4 shows a three-dimensional sectional illustration of a further exemplary embodiment of the optics 1 according to the invention. Again, the arrangement of the light receiving surface 2 and the recess 5 can be seen.
- the optic 1 preferably consists only of the refractive optical waveguide 6.
- the refractive optical waveguide 6 can be designed in several parts or in one piece.
- the one-piece is designed to further simplify the construction.
- an embodiment with 3, 5, 6 or N partially spherical regions of the light emission surface 3 can also be produced.
- the emission characteristic then also has 3, 5, 6, N corners.
- the refractive optical waveguide 6 can furthermore be rotationally symmetrical with respect to a straight line through a center of the light-receiving surface 2.
- the luminaire contains only the luminous means 4 and the optics 1 as light-generating and light-guiding elements.
- FIG. 5 shows a further sectional illustration of an exemplary embodiment of the optical system 1 according to the invention.
- a uniform irradiation of the light into the interior of the refractive Lichtleit stresses 6 is achieved by positioning the bulb 4 in the center of the here partially spherical light receiving surface 2.
- the refractive light guide body 6 the light moves in a straight line to be refracted and emitted at the light emitting surface in accordance with the inclination of the surface at the respective exit point. Due to the inclination, the emission direction of the respective light beam is adjusted.
- the inclination sets the overall light emission characteristic of the luminaire.
- FIG. 6 shows an exemplary illuminance distribution of the exemplary embodiments illustrated in FIGS. 1-5.
- FIG. 7 shows two different illuminance profiles of exemplary luminaires. Here it can be seen that different widths of the light output can be achieved by different constructions of the refractive Lichtleit stresses 6.
- FIG. 8 furthermore shows an intensity distribution, as can be achieved by the exemplary embodiments of FIGS. 1-5.
- the invention is not limited to the illustrated embodiment.
- different shapes of the radiation characteristic can be set by designing the exact surface shape of the refractive light element.
- different bulbs can be used.
