The light emitted by the plurality of LED devices enters the light guide members, is guided by the light guide columns of the light guide members, and is then emitted from the lenses to project an array light spot. Since the LED devices internally encapsulating LED chips have a large volume, the light guide columns of each light guide member are arranged at intervals corresponding to the light emitting surfaces of the LED devices, and the lenses are arranged corresponding to the light emitting surfaces of the light guide members, which results in a large volume of the light emitting device for projecting an array light spot, and the light emitting device cannot meet the requirement of miniaturization. SUMMARY

[0011] In one of the embodiments, the light-in surface of each light guide part is bonded with the light-out surface of the corresponding light-transmissive connector, and the material of the light guide part and the light-transmissive connector is resin material.

[0012] In one of the embodiments, the light-transmissive connector is arranged on the front surface of the light-emitting chip, and the shape of the light-transmissive connector is adapted to the shape of the light guide part, and the side surface of each light guide part is converging in a bowl shape in the light-out direction of the optical axis.

[0013] In one of the embodiments, the light-emitting device further comprises a light-blocking part arranged on the top of the light guide structure and covering the top surface outside the light-out surface of the light guide structure.

[0014] In one of the embodiments, the light-out surface of each light-transmissive connector is convex curved surface, and the light-in surface of each light guide part is concave curved surface.

Since the size of the light-emitting chip is small, the size of the light-transmissive connector is also small accordingly, and the size of the light guide structure is adapted to be small, which leads to the significant reduction of the volume of the light-emitting device, realizing the miniaturization of the light-emitting device. Compared with the traditional way of arranging the light-emitting surface of the LED device and the light-in surface of the light guide column of the light guide part in a spaced manner, the light-in surface of the light guide part and the light-out surface of the light-transmissive connector are adapted and connected in a mutually adhering manner, which can reduce the propagation loss of light on the contact interface, improve the light extraction efficiency, and enable more light to enter the light guide part for light mixing, and the light mixing is uniform.

[0031] Please refer to Figure 1 and Figure 2 , Figure 1 shows a cross-sectional view of a light-emitting device in an embodiment of the present application, Figure 2 shows Figure 1A schematic diagram of a light guide structure of a light emitting device is shown. The light emitting device 100 includes a light emitting assembly 110, a plurality of light transmitting connectors 120, and a light guide structure 130. The light emitting assembly 110 has a plurality of light emitting regions 112 arranged in an array, each of which is formed by a light emitting surface of a light emitting chip 114. The plurality of light transmitting connectors 120 are arranged one-to-one with the plurality of light emitting regions 112, and each of the light transmitting connectors 120 is arranged on the light emitting chip 114 of the corresponding light emitting region 112. The light guide structure 130 is arranged on the light emitting assembly 110 and includes a plurality of light guide portions 132, which are arranged one-to-one with the plurality of light transmitting connectors 120. The light entrance surface of each of the light guide portions 132 is adapted to and connected to the light exit surface of the corresponding light transmitting connector 120.

[0032] The light transmitting connector 120 is arranged directly corresponding to the light emitting chip 114, and each of the light guide portions 132 is arranged corresponding to the light transmitting connector 120. Since the size of the light emitting chip 114 is small, the size of the light transmitting connector 120 is also small, and the size of the light guide structure 130 is adapted to be small, which significantly reduces the volume of the light emitting device 100 and realizes the miniaturization of the light emitting device 100. Compared with the conventional arrangement mode in which the light emitting surface of the LED device is arranged apart from the light entrance surface of the light guide column of the light guide, the light entrance surface of the light guide portion 132 is adapted to and connected to the light exit surface of the light transmitting connector 120, which can reduce the propagation loss of light on the contact interface, improve the light extraction efficiency, and enable more light to enter the light guide portion 132 for mixing, and the mixed light is uniform. Therefore, the array light spot projected from the light guide structure 130 has good brightness and uniformity, and the light spot edge is clear.

[0033] The light emitting assembly 110 includes a plurality of light emitting chips 114 and a substrate 116. The plurality of light emitting chips 114 are arranged on the substrate 116, and each of the light emitting regions 112 can be formed by the light emitting surface of at least one light emitting chip 114. The light emitting chip 114 can be a flip chip or a face-up chip, which can be but is not limited to an LED chip. In this embodiment, each of the light emitting regions 112 is formed by the light emitting surface of one light emitting chip 114, and the volume of the light transmitting connector 120 and the light guide structure 130 can be further reduced to further reduce the volume of the light emitting device 100. In an alternative embodiment, each of the light emitting regions 112 can be formed by the light emitting surface of a plurality of light emitting chips 114, which can include red light chips, green light chips, and blue light chips.

[0034] The substrate 116 can be a plate body provided with a circuit, which not only serves as a carrier for the light emitting chip 114 but also electrically connects the light emitting chip 114 with external devices through the circuit. The material of the plate body can be but is not limited to glass, resin, or ceramic.

[0035] In the embodiment, the side surface of the light-transmissive connecting member 120 is arranged in a diverging manner in the light-out direction of the optical axis, so that the large-angle light emitted by the light-emitting chip 114 is refracted to the light-out surface, and most of the light emitted by the light-out surface is introduced into the light guide portion 132, further reducing the light propagation loss and improving the light extraction efficiency.

[0036] In the embodiment, the light-emitting chip 114 is a vertical chip and only the front surface can emit light. Correspondingly, the light-transmissive connecting member 120 is arranged on the front surface of the light-emitting chip 114 and only covers the front surface of the light-emitting chip 114, so that the volume of the light-transmissive connecting member 120 is smaller, the volume of the light guide portion 132 is further smaller, and the entire light-emitting device 100 can be made smaller. In other embodiments, the side surface of the light-emitting chip 114 can emit light, the light-transmissive connecting member 120 covers the front surface and the side surface of the light-emitting chip 114, and the light-emitting chip 114 can output more light, so that the brightness of the projected light spot is better.

[0037] In the embodiment, the shape of the light-transmissive connecting member 120 is adapted to the shape of the light guide portion 132. Since the light-transmissive connecting member 120 only covers the front surface of the light-emitting chip 114, the volume of the light-transmissive connecting member 120 can be further smaller, and the shape of the light-transmissive connecting member 120 is adapted to the shape of the light guide portion 132, and the side surface of each light guide portion 132 is in a diverging shape in the light-out direction of the optical axis. It should be noted that in other embodiments, the side surface of each light guide portion 132 is in a bowl shape in the light-out direction of the optical axis, and since the curvature of the side surface near the bottom is large, the side surface can reflect light at a small angle upward, and the light is directly emitted through the light-out surface, so that the light guide effect is better.

[0038] In the embodiment, the light-out surface of each light-transmissive connecting member 120 is bonded to the light-in surface of the corresponding light guide portion 132, which is beneficial to improve the bonding effect between the contact interfaces and has good connection stability. In order to further reduce the light propagation loss of the contact interface, the materials of the light-transmissive connecting member 120 and the light guide portion 132 are both resin materials, so as to weaken or eliminate the contact interface between them. During assembly, the light-transmissive connecting member 120 can be pre-solidified on the front surface of the light-emitting chip 114, so as to be initially shaped and in a surface-bondable state, then the light guide structure 130 is positioned on the substrate 116, so that the plurality of light guide portions 132 are bonded to the plurality of light-transmissive connecting members 120 one by one, and finally the light-transmissive connecting member 120 is completely solidified. It can be understood that in other embodiments, the refractive index of the light-transmissive connecting member 120 can be greater than the refractive index of the light guide portion 132, so as to reduce the total reflection loss when the light propagates from the optically dense medium to the optically sparse medium.

[0039] In the embodiment, the light-out surface of each light guide portion 132 is arranged as a plane, and in alternative embodiments, the light-out surface of each light guide portion 132 can be arranged as a convex curved surface or a concave curved surface.

[0040] In the embodiment, the light guide structure 130 further comprises a support part 134, which is arranged on the light emitting assembly 110 and surrounds the outer side of the plurality of light guide parts 132. The light exit surface of each light guide part 132 has at least four edges, and adjacent light guide parts 132 share one edge. Since adjacent light guide parts 132 share one edge, the array of light spots projected after collimation processing has substantially no interval between the light spots, and a larger light spot can be combined, and different patterns can be projected by controlling the on-off of different light emitting areas 112, with good projection effect and wide application scenarios. Moreover, the support part 134 is arranged on the outer side of the plurality of light guide parts 132, which does not affect the light spots projected by the light guide parts 132, and improves the connection strength and stability between adjacent light guide parts 132. It can be understood that in other embodiments, the top of the light guide structure 130 can be provided with a connecting structure, which connects all the light guide parts 132 and the support part 134. However, the connecting structure will cause a significant interval between the light exit surfaces of adjacent light guide parts 132, and further cause a significant gap between the array of light spots projected.

[0041] In the embodiment, the light guide structure 130 is an integral structure, that is, the plurality of light guide parts 132 and the support part 134 are integrally formed. When assembling, the support part 134 is positioned and fixed, and the installation of the light guide parts 132 (lenses) is completed at the same time, without the need to install the support structure first and then install the lenses, thereby simplifying the assembly process and improving the production efficiency. It should be noted that in other embodiments, the light guide structure 130 can be a split structure, which comprises a split support part (equivalent to the support part 134) and a light guide part. The support part is arranged on the substrate 116, and the light guide part is supported on the substrate 116 by the support part. The light guide part has a plurality of light guide parts. Obviously, the split light guide structure 130 has more process steps and low production efficiency, resulting in high cost.

[0042] In order to reduce the influence of the external environment on the light emitting chip 114, the support part 134 is sealingly connected with the substrate 116 of the light emitting assembly 110, thereby achieving the air tightness of the light emitting chip 114, which is beneficial to improve the service life and reliability of the light emitting chip 114.

[0043] In the embodiment, each light guide part 132 is in the shape of a quadrangular frustum, that is, a quadrangular pyramid frustum. The light entrance surface and the light exit surface of each light guide part 132 are both square, and the light entrance surface is smaller than the light exit surface. Each light guide part 132 can correspond to a square light spot, and the array of light spots projected by all the light guide parts 132 can be spliced into a square large light spot, with substantially no gap between adjacent light spots and clear light spot edges. Correspondingly, each light transmission connecting piece 120 is also in the shape of a quadrangular frustum, and the small end of each light guide part 132 is matched with the large end of the corresponding light transmission connecting piece 120.

[0044] It can be understood that in other embodiments, each light guide portion 132 can be in the shape of a hexagonal frustum (hexagonal cone), an octagonal frustum (octagonal cone), or other polygonal frustum, and correspondingly project a hexagonal, octagonal, or other polygonal light spot, and the shape of the light-transmitting connecting piece 120 is adapted accordingly; or each light guide portion 132 can be a regular cylinder, such as a circular cylinder, a quadrangular cylinder, a hexagonal cylinder, an octagonal cylinder, or other polygonal cylinder.

[0045] In this embodiment, the light emitting device 100 further comprises a light blocking piece 140, which is arranged on the top of the light guide structure 130 and covers the top surface of the light guide structure 130 except the light emitting surface, so as to block the light propagating to the part of the top surface and shape the light spot, so that the forming effect of the light spot is better.

[0046] The light blocking piece 140 can be made of a material that blocks the light, such as white resin, or made of a light-absorbing material, such as black resin, which absorbs part of the light.

[0047] In this embodiment, the light emitting device 100 further comprises a lens assembly 150, which is arranged on the light emitting assembly 110 and covers the light guide structure 130. The focal point P of the lens assembly 150 is located on the light emitting surface of the light guide structure 130, so as to collimate the light emitted by the light guide structure 130, so that the edge of the light emitting surface of each light guide portion 132 is substantially equal to the edge of the projected light spot, and the array effect of the light spot is better.

[0048] In this embodiment, the lens assembly 150 comprises a mounting piece 152 and a lens 154. The mounting piece 152 is arranged on the light emitting assembly 110, and the lens 154 is arranged on the mounting piece 152. Obviously, the shape and size of the lens 154 are also adapted to the light emitting surface of the light guide structure 130, and the volume of the lens 154 also decreases as the volume of the light guide structure 130 decreases. The lens 154 of the lens assembly 150 can collimate the light emitted by the light emitting surface of each light guide portion 132, so that the size of the light spot is almost equal to the size of the light emitting surface, the edge of each light spot is clear, and there is no gap between adjacent light spots.

[0049] In this embodiment, the mounting piece 152 can be a housing structure, but is not limited thereto, which can be fixed to the substrate 116 by adhesion. In alternative embodiments, the mounting piece 152 can be fixed to the substrate 116 by screws or buckles, so as to facilitate disassembly and assembly.

[0050] In this embodiment, the lens 154 can be adhered or molded on the mounting piece 152. In other embodiments, the lens 154 can be fixed to the threaded hole of the mounting piece 152 by screw connection, so as to facilitate disassembly and replacement of the lens 154.

[0051] In this embodiment, the lens 154 can be but is not limited to a plano-convex lens, which can collimate the light emitted by the light guide 132, so that the edges of the light emitting surface of each light guide 132 are substantially equal to the edges of the projected light spot, and the light spot arraying effect is better. In other embodiments, the plano-convex lens can be replaced by a Fresnel lens.

[0052] Please refer to Figure 3 and Figure 4 , Figure 3 shows a cross-sectional view of a light emitting device in another embodiment of the present application, Figure 4 shows Figure 3 the light guide structure of the light emitting device in the embodiment, compared with the light emitting device 100 in the above embodiment, the light emitting surface of each light transmission connector 120 in the light emitting device 100 in this embodiment is a convex curved surface, and the light incident surface of each light guide 132 is a concave curved surface, that is, the light emitting surface of the light transmission connector 120 is located in the light incident surface of the light guide 132, the light emitted by the light emitting surface of the light transmission connector 120 all enters the light guide 132, the light propagation loss is less, and the convex curved surface is beneficial to light collection and improves the brightness of the light spot.

[0053] In this embodiment, the light emitting surface of each light guide 132 is a convex curved surface, which increases the physical spacing between the light emitting surfaces of adjacent light guides 132, and the convex curved surface is beneficial to light collection, so that the boundaries between the projected light spot arrays are more clear.

[0054] In this embodiment, in order to further improve the light guiding and light uniformity effect of the light guide structure 130, a reflective layer 142 is arranged on the light guide structure 130, the reflective layer 142 covers the surface outside the light incident surface and the light emitting surface of the light guide structure 130, and can reflect the light emitted from the surface outside the light incident surface and the light emitting surface, better reducing the light propagation loss, and the reflected light is mixed more uniformly, so that the brightness of the projected light spot is better and the uniformity is better; at the same time, the reflective layer 142 on the top surface outside the light emitting surface of the light guide structure 130 can reflect the light propagating to this part of the top surface, shape the light spot, and make the forming effect of the light spot better.

[0055] The reflective layer 142 can be formed by soaking, coating or electroplating process. Taking the soaking process as an example, during processing, first, a protective film is attached to the light incident surface and the light emitting surface of the light guide structure 130, then the light guide structure 130 is soaked in a reflective material, finally, the light guide structure 130 is taken out and the reflective material is dried to form the reflective layer 142, and the protective film is torn off to expose the light incident surface and the light emitting surface.

[0056] As for other aspects of the light emitting device 100 in this embodiment, they are basically the same as those of the light emitting device 100 in the above embodiment, and the specific content can be referred to the description of the above embodiment, which will not be repeated here.

[0057] Please refer to Figure 5 , Figure 5 The cross-sectional view of the light emitting device in another embodiment of the present application is shown. Compared with the convex curved surface of the light emitting surface of each light guide portion 132 of the light emitting device 100 in the above embodiment, the light emitting surface of each light guide portion 132 of the light emitting device 100 in the present embodiment is provided as a flat surface, thus simplifying the structure thereof. Obviously, in other embodiments, the light emitting surface of each light guide portion 132 can also be provided as a concave curved surface.

[0058] As for other aspects of the light emitting device 100 in the present embodiment, they are basically the same as those of the light emitting device 100 in the above embodiment, and the specific content can be referred to the description of the above embodiment, which will not be repeated here.

[0059] The light emitting device 100 of the present application connects the light emitting chip 114 and the light guide portion 132 by providing the light-transmitting connecting piece 120 therebetween. The light-transmitting connecting piece 120 is directly provided corresponding to the light emitting chip 114, and each light guide portion 132 is provided corresponding to the light-transmitting connecting piece 120. Since the size of the light emitting chip 114 is small, the size of the light-transmitting connecting piece 120 is also correspondingly small, and the size of the light guide structure 130 is adapted to be small, thus significantly reducing the volume of the light emitting device 100, and realizing the miniaturization of the light emitting device 100. Compared with the conventional mode in which the light emitting surface of the LED device and the light-incident surface of the light guide column of the light guide piece are spaced apart, the light-incident surface of the light guide portion 132 and the light-emitting surface of the light-transmitting connecting piece 120 are adapted and connected to each other, thus reducing the propagation loss of light on the contact interface, improving the light extraction efficiency, and enabling more light to enter the light guide portion 132 for light mixing. The light mixing is uniform, and therefore, the array light spot projected from the light guide structure 130 has good brightness and uniformity, and the light spot edge is clear.

[0060] It should be noted that the application scenarios of the light emitting device 100 of the present application can be, but are not limited to, illumination, display and projection. Taking the application of the light emitting device 100 in illumination as an example, it can be used as a car light, which can project an array light spot and combine different patterns by controlling the on-off of different light emitting regions 112, thus providing illumination and indication for drivers or pedestrians.

[0061] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0062] The above embodiments only express several implementation ways of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation to the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
