This patent application claims the priority of German patent application 102024 106 761.6, the disclosure content of which is hereby incorporated by reference. Optoelectronic components including LED units with collima- tion structures are known from the state of the art. An objective of the current application is to provide an im- proved optoelectronic component and an improved method of manufacturing an optoelectronic component. Said objective is achieved by the optoelectronic component and the method of the independent claims. Further embodiments are subject of the dependent claims. According to an aspect of the invention an optoelectronic component, especially a light emitting diode LED system, is provided, comprising at least one light emitting diode LED unit and at least one collimation structure for collimation of light emitted by the LED unit, wherein the LED unit com- prises at least one light emitting facet to emit light, wherein the collimation structure comprises at least one re- flector element with at least on reflective surface capable of reflecting the light emitted by the LED unit, and wherein the reflective surface of the reflector element is positioned facing the at least one light emitting facet of the LED unit. Hereby the technical advantage can be achieved that an im- proved electronic component, specifically an improved light emitting diode system, can be provided. The light emitting 2023PF01494 - 2 – diode system comprises at least one light emitting diode unit, LED unit, and at least one collimation structure for collimating the light emitted by the LED unit. For collima- tion of the light emitted by the LED unit, the collimation structure comprises a reflector element with at least one re- flective surface positioned opposite to a light emitting fac- et of the LED unit. Via reflection of the light emitted by the LED unit, specifically emitted by the light emitting fac- et of the LED unit, by the reflection surface of the reflec- tor element, a collimation of the light emitted by the LED unit can be achieved. In this regard, the reflector element of the collimation structure provides a solid, robust and cheap to manufacture solution for collimation of the light emitted by the LED unit. According to an embodiment, reflector element is designed as a planar reflector comprising one planar reflective surface. Hereby the technical advantage can be achieved that an easy to manufacture collimation structure for collimating the light emitted by the LED unit can be provided. According to an embodiment, the reflector element is designed as a cornered reflector comprising at least two planar re- flective surfaces, wherein the at least two reflective sur- faces are arranged in an angle with respect to each other. Hereby the technical advantage can be achieved that by the use of the at least two planar reflective surfaces arranged in an angle with respect to each other, a further improvement of the collimation of the light emitted by the LED unit can be achieved. According to an embodiment, the reflector element is designed as a parabolic reflector with a parabolic reflective surface. Hereby the technical advantage can be achieved that due to the use of the parabolic reflective surface, a further im- 2023PF01494 - 3 – provement of the collimation of the light emitted by the LED unit can be provided. According to an embodiment, the at least one reflective sur- face comprises a metallic reflective layer made of a metallic material. Hereby the technical advantage can be achieved that through the use of the metallic reflective layer in the reflective surface of the reflector element, a high degree of reflectiv- ity of the light emitted by the LED unit can be achieved. Thus, a loss of lighting efficiency of the LED system due to the collimation of the light emitted by the LED unit can be limited to a minimum. According to an embodiment, the at least one reflective sur- face of the reflector element comprises a reflective layer designed as a Distributed Bragg Mirror. Hereby the technical advantage can be achieved that with the use of a Distributed Bragg Mirror as element of the reflec- tive surface of the reflector element, a high degree of re- flectivity of the reflective surface can be achieved. Thus, the loss in lighting efficiency of the LED system due to the collimation of the light emitted by the LED unit can be lim- ited to a minimum. According to an embodiment, the reflective surface of the re- flector element comprises a reflective layer designed as a meta-grating. Hereby the technical advantage can be achieved that due to the use of the meta-grating as part of the reflective surface of the reflector element, a degree of reflectivity can be achieved. Further, the meta-grating provides a robust and easy to manufacture solution for a reflector element. 2023PF01494 - 4 – According to an embodiment, the LED unit is positioned in a focus point of the reflector element. Hereby the technical advantage can be achieved that due to the positioning of the LED unit in the focus point of the re- flector element, a high degree of collimation of the light emitted by the LED unit via the reflective surface of the re- flector element can be achieved. Thus, the loss in lighting efficiency of the LED system due the collimation can be lim- ited to a minimum. According to an embodiment, a diameter of the at least one reflective surface is larger than a width of the LED unit, advantageously by a factor of 2, more advantageously by a factor of 5, most advantageously by a factor of 10. Hereby the technical advantage can be achieved that due to the large dimensions of the reflective surface of the reflec- tor element with respect to dimensions of the LED unit and in specific of the light emitting facet, a maximum amount of the light emitted by the LED unit can be reflected by the reflec- tive surface of the reflector and therefore can be collimated by the collimation structure. As a result, the loss of light- ing efficiency of the LED system due to the collimation of the light emitted by the LED unit can again be limited to a minimum. According to an embodiment, the collimation structure further comprises a coupling material positioned between the LED unit and the reflector element, wherein the coupling material is coupled to the at least one emitting facet of the LED unit and the at least one reflective surface of the reflector ele- ment. Hereby the technical advantage can be achieved that with the coupling material, a solid and robust coupling between the LED unit and the collimation structure and in particular of the LED unit and the reflector element can be achieved. By 2023PF01494 - 5 – filling the space between the LED unit and the reflective surface of the reflector element, a robust LED system can be provided. According to an embodiment, the coupling material is a high index material. Hereby the technical advantage can be achieved that due to the high index material used as coupling material, losses in lighting intensity due to the coupling material placed in the light path between the light emitting facet of the LED unit and the reflective surface of the reflector element can be limited. Reflection effects on surfaces of the coupling mate- rial which would lead to losses in lighting intensity can be reduced to a minimum due to the high optical index. According to an embodiment, the at least one LED unit is de- signed as a feed forward LED unit or as a volume emitting LED unit. Hereby the technical advantage can be achieved that the LED system of the current invention can be provided with multiple different types of LED units. According to an embodiment, the emitting facet of the feed forward LED unit is connected to an outer surface of the cou- pling material, or the volume emitting LED unit is at least partially integrated into the coupling material, such that at least two emitting facets of the volume emitting LED unit are coupled to the coupling material. Hereby the technical advantage can be achieved that a tight and solid connection between the LED unit and the coupling material can be provided. By at least partially integrating the LED unit, designed as a volume emitting LED unit, into the coupling material, it can be achieved that a high amount of light emitted by the LED unit via the at least light emit- ting facets can be introduced into the coupling material and 2023PF01494 - 6 – therefore can be guided to the reflective surface of the re- flector element and thus can be collimated. As a result, a high amount of light emitted by the LED unit, designed as a volume emitting LED unit, can be collimated by the collima- tion structure. According to an embodiment, the LED unit is designed as an RGB LED unit, wherein the RGB LED unit is designed as a stacked RGB LED unit comprising a red active layer, a green active layer and a blue active layer stacked on top of each other, or wherein the RGB LED unit comprises a red LED ele- ment, a green LED element and a blue LED element arranged next to each other. Hereby the technical advantage can be achieved that the LED system of the current invention can be used as a mono-colour and multi-colour LED system. By designing the RGB LED unit as a stacked RGB LED unit, a compact and robust LED unit can be provided. By designing the RGB LED unit with three individual mono-colour LED elements, an easy to manufacture RGB LED unit can be provided. According to an embodiment, the LED unit is designed as a μ- LED unit or mini-LED unit. Hereby the technical advantage can be achieved that the LED system of the current invention can be used for µ-LED units. According to an embodiment, the LED unit comprises a reflect- ing surface opposite to the at least one light emitting fac- et. Hereby the technical advantage can be achieved that due to the reflecting surface of the LED unit positioned opposite to the at least one light emitting facet, the light intensity of the light emitted via the light emitting facet of the LED unit can be enhanced. Hereby, a high intensity front feed LED unit can be provided 2023PF01494 - 7 – According to an aspect of the invention, a method of manufac- turing an optoelectronic component of any of the previous em- bodiments is provided, comprising: providing a LED unit; providing a collimation structure with a reflector element with at least one reflective surface; connecting the LED unit with the collimation structure with a light emitting facet of the LED unit facing the at least one reflective surface. Hereby the technical advantage can be achieved that an im- proved method of manufacturing an optoelectronic component, in specific a LED system, with the technical advantages of the above-mentioned embodiments can be provided. According to an embodiment, the providing of the collimation structure comprises: providing a bulk element of a coupling material, wherein the coupling material is a high index material, wherein the bulk element has a first surface and an opposing second surface, and wherein the second surface has a planar shape, a cornered shape or a parabolic shape; and applying the at least one reflective surface onto the second surface of the bulk element by means of chemical vapor depo- sition, epitaxy growth or glueing procedures; and wherein the connecting of the LED unit to the collimation structure com- prises: applying the LED unit onto the first surface of the bulk ele- ment by means of glueing procedures. Hereby the technical advantage can be achieved that an easy manufacturing process for an LED system according to the above-mentioned embodiments can be provided. For this, a bulk element of the coupling material with a first surface and an opposing second surface is provided. The opposing second sur- face comprises a planar shape, a cornered shape, with at least two angled surfaces, or a parabolic shape.

The above-described properties, features and advantages of this invention, as well as the manner in which they are achieved, become clearer and more clearly understandable in connection with the following description of the embodiments, which are explained in more detail in connection with the drawings.

Figure 1 shows a schematic view of an optoelectronic compo- nent 100 according to an embodiment. 2023PF01494 - 9 – According to the invention, the optoelectronic component 100 is designed as a light emitting diode LED system, comprising at least one light emitting diode LED unit 101 and at least one collimation structure 103. The collimation structure 103 is used for collimating the light 139 emitted by the LED unit 101 and comprises a reflector element 107 with at least one reflective surface 109. The LED unit 101 and the reflector element 107 are positioned with respect to each other such that the reflective surface 109 faces a light emitting facet 105 of the LED unit 101. In the shown embodiment, the reflector element 107 is de- signed as a planar reflector and the reflective surface 109 is designed as a planar surface. In the shown embodiment, the collimation structure 103 fur- ther comprises a coupling material 117. The coupling material 117 is positioned between the LED unit 101 and the reflector element 107. In particular, the coupling material 117 couples the light emitting facet 105 of the LED unit 101 with the re- flective surface 109 of the reflector element 107. Therefore, the coupling material 117 is positioned in the light path of the light 139 emitted by the LED unit 101. According to an embodiment, the coupling material 117 is a high index material. According to the shown embodiment, the coupling material 117 is provided as a bulk element 135 comprising a first surface 119 and an opposing second surface 137. In the shown embodi- ment, the first and second surfaces 119, 137 are oriented parallel to each other. In the shown embodiment, the LED unit 101 is connected to the first surface 119. In particular, the light emitting facet 105 of the LED unit 101 is connected to the first surface 119 of the coupling material 117. 2023PF01494 - 10 – The reflective surface 109 of the reflector element 107 is connected to the second surface 137 of the coupling material 117. In the shown embodiment, the LED unit 101 is designed as a feed forward LED unit and comprises only one light emitting facet 105. Opposite to the light emitting facet 105, the LED unit 101 further comprises a reflecting surface 133. The light emitting facet 105 is part of an active layer 141 of the LED unit 101. The active layer 141 can be n-side of p- side. According to the shown embodiment, the reflective sur- face 109 comprises a metallic reflective layer 111. The me- tallic reflective layer 111 comprises a metal material, for example gold Au, silver Ag, aluminum Al or other metallic ma- terials used for reflective surfaces known from the state of the art. The light 139 emitted by the LED unit 101 is emitted in a light emitting direction 151 towards the reflector element 107 and the reflective surface 109. At the reflective surface 109, the light 139 emitted by the LED unit 101 is reflected roughly into an outgoing direction 153 of the LED system. The outgoing direction 153 is oriented in opposite direction to the light emitting direction 151 of the LED unit 101. The outgoing direction 153 defines the direction of light emis- sion of the LED system. The outgoing light 149 in the embodiment of Figure 1 is roughly directed in the outgoing direction 153. However, the outgoing light 149 still has a substantial degree of disper- sion. The collimation efficiency of the collimation structure 103 therefore is not perfect. According to an embodiment, the reflective surface 109 of the reflector element 107 can, as an alternative or an addition to the above-mentioned metallic reflective layer 111, com- 2023PF01494 - 11 – prise a Distributed Bragg Mirror 113 and / or a meta-grating 115. Figure 2 shows a further schematic view of the optoelectronic component 100 according to a further embodiment. The embodiment of the current invention shown in Figure 2 is based on the embodiment in Figure 1 and comprises the majori- ty of features shown in Figure 1. In contrast to the embodiment in Figure 1, in the shown em- bodiment, the reflector element 107 is designed as a cornered reflector comprising at least two planar reflective surfaces 109. The two planar reflective surfaces 109 shown in Figure 2 are arranged in an angle θ with respective to each other. As a result, in the shown embodiment, the second surface 137 of the coupling material 117 comprises a cornered shape with two planar surfaces arranged in an angle with respect to each other. Due to the angle θ between the two planar reflective surfaces 109, a higher degree of collimation of the light 139 emitted by the LED unit 101 can be achieved. In the current embodiment, the reflective surface 109 again is shown as a metallic reflective layer 111. In addition or alternatively, the reflective surface 109 can comprise a Dis- tributed Bragg Mirror 113 or a meta-grating 115. In graphic a), the LED unit 101 is designed as a feed forward LED unit, identical to the embodiment in Figure 1. The feed forward LED unit 101 is connected via the light emitting fac- et 105 to the first surface 119 of the coupling material 117. In graphic b), the LED unit 101 is designed as a volume emit- ting LED unit and comprises at least two light emitting fac- ets 105. In the embodiment shown in graphic b), the LED unit 101 is integrated at least partially into the coupling mate- rial 117. Due to this at least partial integration, a connec- 2023PF01494 - 12 – tion of the multiple light emitting facets 105 of the volume emitting LED unit 101 with the coupling material 117 can be achieved. The outgoing light 149 of the embodiment in Figure 2 clearly shows a smaller degree of dispersion. Depending on the value of distance d and angle θ, the degree of collimation of the outgoing light 149 can be modified according to the applica- tion. According to an embodiment, a diameter D is larger than a width W of the LED unit 101 and in particular of the light emitting facet 105, advantageously by a factor of 2, more ad- vantageously by a factor of 5, most advantageously by a fac- tor of 10. According to an embodiment the angle θ is between 30° and 90°. The width w of the LED unit 101 can be in the range of 500nm to 100 µm. The diameter D can be more than 2 times, for example be 5 times, the width w of the LED unit. And the dis- tance d can be half the diameter D and can be designed de- pending on the angle θ. Figure 3 shows a further schematic view of the optoelectronic component 100 according to a further embodiment. The embodiment in Figure 3 is based on the embodiment in Fig- ure 1 and comprises the features shown in Figure 1. In contrast to Figure 1, in the shown embodiment, the reflec- tor element 107 is designed as parabolic reflector with a parabolic reflective surface 109. Graphic b) clearly shows the parabolic shape of the parabolic reflective surface 109 with the LED unit 101 being positioned in a focus point FP of the parabolic reflective surface 109. Graphic a) shows a top view of the LED system with the para- bolic reflective surface 109 having a circular cross section 2023PF01494 - 13 – with the LED unit 101 being positioned in a centre of the circular cross section, with the centre being the focus point FP of the reflector element 107. Comparable to the embodiments in Figure 2, the diameter D of the reflective surface 109 is larger than the width W of the LED unit 101, in particular of the light emitting facet 105, by a factor of 2, more advantageously by a factor of 5, most advantageously by a factor of 10. Illustrated in graphic b), the parabolic shape of the reflec- tive surface 109 leads to an effective collimation of the light 139 emitted by the LED unit 101. By positioning the LED unit 101 in the focus point FP of the parabolic reflective surface 109, the outgoing light 149 reflected by the reflec- tive surface 109 in the outgoing direction 153 is almost par- allel and therefore almost perfectly collimated. In the shown embodiment, the parabolic reflective surface 109 is illustrated as comprising a metallic reflective layer 111. In addition or alternatively, the parabolic reflective sur- face 109 can comprise a Distributed Bragg Mirror 113 and / or a meta-grating 115. Figure 4 shows a further schematic view of the optoelectronic component 100 according to a further embodiment. The shown embodiment in Figure 4 is based on the embodiment of Figure 3 and comprises all features shown in Figure 3. In contrast to Figure 3, in the shown embodiment, the para- bolic reflective surface 109 comprises multiple layers of curved Distributed Bragg Mirrors 113 in combination with a metallic reflective layer 111. By combining the Distributed Bragg Mirrors 113 and the metallic reflective layer 111, a higher reflectivity of the reflective surface 109 can be achieved. 2023PF01494 - 14 – Figure 5 shows a further schematic view of the optoelectronic component 100 according to a further embodiment. The embodiment in Figure 5 is based on the embodiment in Fig- ure 4 and comprises all features shown in Figure 4. In contrast to Figure 4, in the shown embodiment, the LED unit 101 is designed as an RGB LED unit 101. In the shown em- bodiment, the RGB LED unit 101 comprises a red LED element 127, a green LED element 129 and a blue LED element 131. The three LED elements 127, 129, 131 are arranged next to each other on the first surface 119 of the coupling material 117 and are positioned roughly in the focus point FP of the para- bolic reflective surface 109. The emitted red light 143 emit- ted by the red LED element 127, the emitted green light 145 emitted by the green LED element 129 and the emitted blue light 147 emitted by the blue LED element 131 are reflected by the parabolic reflective surface 109 into the outgoing di- rection 153, and the red outgoing light 155, the green out- going light 157 and the blue outgoing light 159 travelling in outgoing direction 153 are mostly parallel and therefore highly collimated. Figure 6 shows a further schematic view of the optoelectronic component 100 according to a further embodiment. The embodiment shown in Figure 6 is based on the embodiment in Figure 5. In the shown embodiment, the RGB LED unit 101 is designed as a stacked RGB LED unit 101 and comprises a red active layer 121, a green active layer 123 and a blue active layer 125 stacked on top of each other. The three active layers 121, 123, 125 generate the respective red light 143, green light 145, blue light 147 emitted from the light emitting facet 105 in light emitting direction 151. 2023PF01494 - 15 – Figure 7 shows a further schematic view of the optoelectronic component 100 according to a further embodiment. The shown embodiment is based on the embodiments shown in Figure 1, 2 and 3 and comprises all features shown in these Figures. In the shown embodiment, the reflective surface 109 comprises multiple layers of Distributed Bragg Mirrors 113 and at least one meta-grating 115 stacked on top of the Distributed Bragg Mirrors 113. By specifically designing the meta-grating 115, the layer of the meta-grating 115 can act as a planar reflective surface 109, comparable to the embodiment shown in Figure 1, or as a cornered reflective surface 109, similar to the embodiment shown in Figure 2, or as a parabolic reflective surface 109, similar to the embodiment shown in Figure 3. The combination of the meta-grating 115 with the multiple layers of Distributed Bragg Mirrors 113 increases the reflec- tivity of the reflective surface 109 and therefore reduces the loss in light energy due to the collimation process. According to an embodiment, the layer of the meta-grating 115 can be manufactured from a high index material, such as tita- nium dioxide or other high index materials suitable for meta- gratings known from the state of the art. According to an embodiment, the Distributed Bragg Mirrors 113 can be manufactured from materials such as SiO2 / Nb2O5or SiO2 / HfO2or other materials suitable for Distributed Bragg Mirrors known from the state of the art. In the embodiment of Fig. 7 the LED unit 101 can also be an RGB LED unit 101 as shown in Fig. 5 and Fig. 6. 2023PF01494 - 16 – The embodiments shown on Fig.1 to Fig. 7 can be combined in ways not explicitly shown in the figures. For manufacturing an optoelectronic component 100 according to the above-mentioned embodiments, in a first method step a LED unit 101 is provided. In a further method step, a collimation structure 103 with a reflector element 107 with at least one reflective surface 109 is provided.

The second surface 137 can be provided with a planar shape and / or a cornered shape and / or a parabolic shape. The at least one reflective surface 109 of the reflector element 107 can be applied onto the second surface 137 of the bulk element 135 by means of chemical vapor deposition, epitaxy growth proce- dures, glueing procedures or structuring procedures. In another method step, the LED unit 101 is connected to the collimation structure 103 with the light emitting facet 105 of the LED unit 101 facing the at least one reflective sur- face 109. The LED unit 101 can be applied onto the first sur- face 119 of the bulk element 135 by means of glueing proce- dures.
