Definitions
- LED light sources emit light in very wide solid angles. As a result, they are virtually unusable without optics for lighting tasks or decoration tasks.
- Different optics for LED light sources are known, which set the bundling of the widely scattered LED light or a deflection of the light in certain solid angles to the goal.
- An example of this is given in US Pat. No. 5,349,504, in which a light-conducting solid body is placed in a housing, which enables the redirection of light from two parallelly arranged LED light sources to two separate light exit surfaces via a special beam path.
- the present invention is an optical device according to the features of the preamble of claim 1.
- the object of the present invention is to provide an optical device for LED light sources that produces collimated light that is within a half-angle of max. 60 ° around a defined main axis has a well-defined intensity distribution curve, with multiple major axes can be defined.

- the optical device serves the purpose of focusing light from LED sources by means of a body having a substantially rectangular plan. This is also advantageous, among other things, because a large part of the luminaires used today are rectangular.
- the first optical component - and thus also the optical device which comprises in its optically active part at least one such first optical component - has a refractive index which differs at least by +/- 0.1 from 1.
- the first optical part, as well as the optical device have an xy edge and a (-x) - (- y) edge, an xz edge and a (-x) - (- z) edge, and a yz edge and (- y) - (- z) edge, where the (-x) - (- y) edge and possibly also the yz edge or (-y) - (- z) edge serve as main exit surfaces for the light.
- only one major axis can be defined (exit surface on the (- x) - (- y) flank of the first optical component or optical device), and ideally the light is within a half angle of 4 ° 40 ° have a distribution which is as rectangular as possible, a broad maximum with an intensity of more than 80% of the light emerging from the optics, steepest possible flanks and a smallest possible minimum with less than 10% of the light emerging from the optics being outside the desired angle the main axis is aimed around.
- main axes of the light exit are often desired, which can be located either on the xy flank of the optical device by the configuration of the beam path in the device or the first optical item or on the (-x) - (- y) Flank and the yz flank or (-y) - (- z) flank of the same, in which case all these flanks form main exit surfaces for the light.
- Both the first optical part and the optical device are limited by a plurality of outer surfaces, which preferably each perform an optical function, for example as a reflector and / or as a lens and / or beam splitter etc.
- Each cavity has cavity limiting cavity interfaces which act as mirrors and / or lenses and / or beam splitters within the item or optical device. Due to the specific design and arrangement of the cavities or the beam path can be adapted to the respective requirements.
- the cavities preferably extend in their longitudinal extension parallel to the y-direction, wherein they are in particular configured as cavities extending from the x-z flank to the (-x) - (- z) flank. The latter allows a particularly simple production of the cavities.
- the cavities can currently be produced particularly economically by laser cutting, the laser preferably acting in the normal to the x-z or ⁇ (-x) - (- y) plane.
- the mirror-smooth boundary surfaces of the cavities act in such a way that light is transmitted almost undeflected or almost totally reflected.
- optical device can be achieved if several individual parts are combined to form such an optical device and the individual parts are in particular twisted together so that their axes x, y, z appear to be interchanged in the finished optical device.
- beam splitter lights which have several major axes of radiation, around which within a certain angle, the light radiates in a defined intensity curve.
- the technology described here allows particularly pronounced flat optics and optics of 3-Dimensional highly complex shape - eg as a snowflake, or as quartz-faux, or in any other crystal forms and other forms (hedgehogs, sea urchins, trees, leaves ...) each adapted to the smallness of the light source.
- the optical device has a single part that serves to connect to the LED.
- this is designed so that the item can be easily screwed onto the board with the LED or otherwise positively or positively connected to the board.
- the item is preferably configured so that the one or more optically active parts of the optical device can be connected to the item by simple pressing, for example.
- the individual part serving for the connection with the LED light source is designed as an optical individual part and can be integrated into the optical device so that the beam path can also be passed through this individual part.
- the item used to connect to the LED light source is designed to fix the light source exactly in the place provided so that it moves only within the given tolerances, ie in the range of, for example, 5/100 to 1/10 mm can, and thus ensures that the light radiates very specifically in the optical device and thus in the desired manner in the environment.

If one thinks of a virtual outer surface, which is called envelope in the following, which comprises the outer surface 16 with its openings 18, this envelope results in the projection in an xy plane a rectangle, as can be seen also in FIG.
- the xy flank opposite the (-x) - (- y) flank has an outer surface 20 whose envelope, when projected into an xy plane, also gives a rectangle.
- the expansion of this rectangle in the x direction, however, corresponding to the curvature of the outer surfaces 7 is less than that of the outer surface 16.

- Light beam 8 2 is reflected at the boundary surfaces of the cavity 2 and emerges approximately parallel to the beams 8 i, 8 2 via the outer surface 16.
- Light beams 8 3 , 8 4 enter directly into the body of the first optical component 10 via the side wall 23, with light beam 8 3 reflecting from the inside on the side wall 23 and on the boundary surface of the cavity 2, so that it finally approaches as a directed beam 83 emerges parallel to the beams 8 1 ( 8 2, 8 2 'from the outer surface 16.

- Recess 22 for receiving an LED light source 6 on the recess 22 extends in this case in (-z) direction but only about a quarter in the body of the second optical component 10 'into it.
- the bottom 3 is again formed barrel-like arched into the recess 22.
- the side walls 23 first narrow the recess 22 in order to then expand it towards the bottom 3 again.
