    Light collector with mouth elementThe present invention relates to a light collector with an orifice element according to the preamble of the independent claim.
    Background of the inventionTo focus light on a point, lenses and lenses are typically used, focusing light from a light source on a focal point located at a certain distance from the lens and at a position determined by the angle of incidence of the incident light. In order to stabilize the position of the focal point, the distance between the lens and a receiving element must be kept fixed and, in addition, the direction of the lens relative to the light source must be kept fixed with great accuracy.
    An object of the invention is therefore to provide a light collector which collects incident light on an orifice element.
    These and other purposes are achieved by a light collector with an orifice element according to the cantilevered parts of the independent claim.
    Summary of the inventionThe invention relates to a light collector 1 with a main axis intended to be directed towards incident light, the light collector comprising at least one substantially flat transparent element 1, 1a-b which extends from the main axis and is angled from the main axis by the angle 90 ° 43. The transparent element 1, 1a-b has a flat side facing away from the side receiving incident light and has a stepped side facing the incident light. At the main axis, the transparent element 1, 1a-b is optically connected to an orifice element 5 which extends in the direction of the main axis. The steps of the step-shaped side have upper surfaces which are angled relative to the flat side of the mouth element with the angle α and short sides which are substantially parallel to the main axis. Eli such a light collector can be produced with little material access and on advantageous Aft collect a lot of light Over a small output aperture.In a particularly advantageous embodiment, the last short side of the step-shaped side next to the mouth element is angled from the main axis so that light which is guided in the transparent element towards1the mouth element is reflected down into the mouth element by the last short side.
    The light collector 1 can be designed so as to comprise two planar transparent elements 1, 1a-b on each side of the orifice element 5 or be designed so that the transparent element 1, 1a-b substantially projects a conical surface with the orifice element 5 at the tip of the cone. .
    The invention furthermore relates to such a light collector which in addition comprises a transparent downboard protection 6a-b which projects over the surface formed by the edges of the transparent elements 1, 1a-b which are furthest from the orifice element. In a particularly advantageous embodiment, the downboard cover 6a-b is formed as part of a sfdr.
    Brief description of the figuresFig. 1 shows the middle part of a first embodiment of the light collector Fig. 2 shows the first embodiment of the light collector in its entirety Fig. 3 shows a second embodiment of the light collectorFig. 4 shows a third embodiment of the light collectorDescription of four embodimentsFig. 1 shows the middle portion of a first embodiment of the light collector. The light collector has a function reminiscent of a focusing lens, but is designed completely differently. The light collector has two symmetrically arranged wings, a left wing 1a and a right wing 1b. Both wings are mainly flat, transparent discs with completely flat undersides. Both wings are at angles from what in the figure is the horizontal plane with the angle 13, ddr p in the hdr embodiment is 0. In practice, the light collector is directed first towards the light source and 13 is not shaved cid from the horizontal plane.
    The upper sides of the light collector's two wings comprise a step-shaped structure, the usual step has a vertical short side 2 and a top side 3 which is angled from the underside of the wing by the angle a. The angle a is adapted to achieve complete internal reflection inside the wing and in the 14.24 °. The selected angle is hdr adapted few a light collector made in2PMMA, but Mr other materials, other angles are optimal.
    Light which falls towards the light collector from a direction which in the figure is vertical or almost vertical will be deflected when it passes the graphene surface between air and the top of a step. The curved light will then again undergo complete internal reflection towards the underside of the wing. The reflected light then reaches the top of a step and is reflected down towards the next step. The reflections are repeated until the light from all the steps of the Watt light collector is in the middle.
    At the center of the light collector, the light on both wings is a short side 4 of a step that is not vertical but angled slightly towards each wing. At these oblique short sides 4, the light is reflected downwards and into an orifice element 5 which extends vertically in the downward direction. The lower surface of the orifice element 5 is the surface for which the collected light leaves the light collector and can be used for the desired purpose. From the orifice element, the light can advantageously be passed on with a light guide with the same cross section as the orifice element.
    The figure shows a two-dimensional view and can refer to a cross-section through two substantially flat wings 1a-b angled to each other by 600 and in that case the mouth element consists of an elongate block-shaped element which extends into the plane of the paper. This gives light collected along a line of a certain width.
    The orifice shape can also be substantially conical and the figure thus shows a cross section through this cone. What in the figure looks like a separate left and right wing are thus both parts of the same element that extend over a conical surface. In this variant, the orifice element is constituted by a cylindrical element and this thus gives light collected along a point with a certain extent.
    Fig. 2 shows the first embodiment of the light collector in its entirety, with incident light illustrated as downwardly directed arrows above the wings and collected light illustrated by arrows emanating from the orifice element. The light is illustrated with vertically directed arrows that indicate the direction of the incident light, but the light collector also accepts and collects light that falls from a deviating direction, however with a maximum deviation above which the light is not directed to the mouth element.
    The figure also illustrates how the light radiating from the orifice element has a distribution of directions centered around the vertical. This distribution arises because light as3hits the different surfaces of different steps in different places% tier different paths fi-am to the mouth element and will alarm this with different directions.
    Fig. 3 shows a second embodiment of the light collector which also comprises a downboard cover 6a. The downboard cover 6a is flat and extends over the upper part of the light collector, frail the upper edge of one wing to the upper edge of the opposite wing. If the light collector is conical, the precipitation protection consists of a circular element and in all circumstances the precipitation protection is transparent to light.
    Fig. 4 shows a third embodiment of the light collector with a convex downboard protection 6b which gives better drainage than that illustrated in Fig. 3. If the light collector is conical, the downboard protection 6b is shaped as part of a War and can be rigid or held in raft shape throughout the device is released under pressure so that the precipitation protection is biased up to the desired shape.4
