Description

Lighting device and lighting module including the same

[0001] An embodiment of the invention relates to a lighting device and a lighting module including the same.

[0002] Recently, lighting devices composed of hundreds or thousands of small LEDs are being applied to automotive lighting modules, and various pixel lighting technologies are being proposed, particularly for automotive lighting modules.

[0003] For example, since pixel lighting technology is applied to lighting devices to allow each LED to be controlled independently, it is possible to adjust the lighting according to the surrounding environment or create various lighting effects to produce unique signature lighting.

[0004] Meanwhile, FIG. 1 is a drawing showing a lighting device with pixel lighting technology applied. Referring to FIG. 1, each pixel area of ​​the lighting device has the same shape and the same number of light sources (120), and there is a problem that visibility is reduced when displaying information such as text or images due to the partition wall (115) placed between each light source (120). In addition, a lens part (112) is spaced apart from the light source (120) with an air gap in between, and the lens part (112) is positioned higher than the partition wall (115), so there is a problem that it is difficult to implement surface light emission.

[0005] One of the technical challenges of the embodiment is to improve visibility when displaying images or information, such as logos, symbols, or characters.

[0006] In addition, one of the technical challenges of the embodiment is to improve the degree of freedom in lighting design of the lighting device.

[0007] In addition, one of the technical challenges of the embodiment is to highlight information, such as text or images, provided through a lighting device and to improve aesthetics.

[0008] The technical problems of the embodiments are not limited to those described in this section and include those that can be identified through the description of the invention.

[0009] A lighting device according to an embodiment comprises: a substrate; a plurality of light-emitting regions disposed on the substrate and having a light source; a partition disposed between each of the plurality of light-emitting regions; a molding layer covering the light source within the light-emitting region; and a diffusion layer disposed on the molding layer; wherein the plurality of light-emitting regions may include a first light-emitting region having a first light source and a second light-emitting region having a plurality of second light sources.

[0010] Additionally, in the embodiment, the second light source may be arranged in the form of (m1 x n1), (m1:1, n1:2 or greater integer).

[0011] In addition, the embodiment further includes a third light-emitting region having a plurality of third light sources, and the third light sources may be arranged in a matrix form of (m2Xn2), (m2: an integer greater than or equal to 2, n2: an integer greater than or equal to 2).

[0012] Additionally, in the embodiment, the partition wall may not be located between each of the second light source and between each of the third light source.

[0013] In addition, in the embodiment, the height of the upper surface of the molding layer may be lower than the height of the upper surface of the partition wall.

[0014] In addition, in the embodiment, the height of the lower surface of the diffusion layer may be lower than the height of the upper surface of the partition wall.

[0015] In addition, in the embodiment, the area of ​​the third light-emitting region may be larger than the area of ​​the second light-emitting region.

[0016] In addition, in the embodiment, the area of ​​the second light-emitting region may be larger than the area of ​​the first light-emitting region.

[0017] In addition, in the embodiment, the first light-emitting region and the second light-emitting region may display different colors.

[0018] In addition, in the embodiment, the partition wall may have a black color.

[0019] The lighting device according to the embodiment has a technical effect that can improve visibility when displaying images or information such as logos, symbols, or characters.

[0020] For example, an embodiment may improve visibility by providing a point light source, a line light source, and a surface light source within a single lighting device and selectively operating the light source according to the information being displayed.

[0021] In addition, the embodiment has the technical effect of providing various information by improving the degree of freedom of the lighting patterns that can be implemented.

[0022] For example, the embodiment may improve the degree of freedom of the lighting pattern by arranging light-emitting regions of different areas or shapes rather than repeating the same pixel light source.

[0023] In addition, the embodiment can highlight information such as text or images and has the technical effect of improving aesthetics.

[0024] For example, the embodiment may display the colors of the first, second, and third light-emitting regions differently or implement them in the form of a gradient to highlight the display information and improve aesthetics.

[0025] The technical effects of the embodiments are not limited to those described in this section and include those that can be understood through the description of the invention.

[0038] FIG. 2 is a cross-sectional view of a lighting device (101) according to an embodiment. Referring to FIG. 2, the lighting device (101) may include a substrate (110), a light source (120), a light-emitting region (130), a partition (115), a molding layer (119), and a diffusion layer (118). Specifically, a light-emitting region (130) having a light source (120) and a partition (115) disposed around the light-emitting region (130) may be disposed on the substrate (110). Additionally, a molding layer (119) may be disposed to cover the light source (120) within the light-emitting region (130). Additionally, a diffusion layer (118) may be disposed on the molding layer (119). The diffusion layer (118) may include the molding layer (119) and a resin material. And the diffusion layer (118) may contain impurities such as a diffusion agent inside, and the diffusion agent may include at least one of Al2O3, TiO2, SiO2, ZnO, and ZrO2.

[0039] The lighting device (101) displays images or information such as symbols, logos, symbols, or characters by means of the light sources (120) each placed within the light-emitting area (130), and can be defined as a lighting module or a display lamp.

[0040] The lighting device (101) controls the operation of a light source (120) within a light-emitting area (130) through a control unit (not shown) according to the image or information to be displayed, and displays the image or information by the light extracted through the light-emitting area (130) by the turn-on or turn-off of the light source (120). The light source (120) placed within the light-emitting area (130) is turned on or turned off depending on whether power is supplied. The light-emitting area (130) can be implemented as a grid type or a unit cell type and can function as a pixel, which is the smallest unit constituting the image or information.

[0041] Additionally, the substrate (100) may include a printed circuit board (PCB). The substrate (100) may include, for example, at least one of a resin-based printed circuit board (PCB), a metal core PCB, a flexible PCB, a ceramic PCB, or an FR-4 substrate. If the substrate (100) is a flexible PCB, the lighting device (101) may have flexible characteristics.

[0042] Additionally, the molding layer (119) may be a transparent resin material, such as UV (Ultra violet) resin, silicone, or epoxy. The molding layer (119) may cover the upper and lower surfaces of the light source (120). In one example, the molding layer (119) may not include beads. Meanwhile, the present disclosure is not limited thereto, and the molding layer (119) may be implemented to include beads, a diffuser, a phosphor, ink, etc. The molding layer (119) may control the distance between the light source (120) and the diffusion layer (118) through optical design.

[0043] In addition, the above-mentioned diffusion layer (118) can realize a surface light source by scattering light emitted from a light source (120) through a light diffuser to improve surface uniformity.

[0044] Additionally, the partition (115) can prevent interference between adjacent light-emitting regions (130). For example, the partition (115) may include a black color. As an example, the partition (115) may include a resin material, such as silicone or epoxy material. The partition (115) may include a light-absorbing material such as carbon black within the resin material, or a reflective material such as TiO2, SiO2, or Al2O3. As another example, the partition (115) may include a metal material, and the metal material may be an alloy of at least one or more of aluminum (Al), nickel (Ni), copper (Cu), and silver (Ag).

[0045] Additionally, the height of the upper surface of the molding layer (119) may be lower than the height of the upper surface of the partition wall (115).

[0046] Additionally, the height of the lower surface of the diffusion layer (118) may be lower than the height of the upper surface of the partition wall (115).

[0047] Meanwhile, the light-emitting region (130) may include a first light-emitting region (131), a second light-emitting region (132), and a third light-emitting region (133). A first light source (121) may be placed within the first light-emitting region (131), a second light source (122) may be placed within the second light-emitting region (132), and a third light source (123) may be placed within the third light-emitting region (133).

[0048] At this time, the number of light sources placed inside each of the first light-emitting region (131), the second light-emitting region (132), and the third light-emitting region (133) may differ from each other.

[0049] Specifically, for example, the first light source (121) disposed within the first light-emitting region (131) may be one. Accordingly, the first light-emitting region (131) may be referred to as a point light source. In one example, the first light-emitting region (131) may have a size corresponding to one pixel. In another example, the first light-emitting region (131) may have a size corresponding to multiple pixels.

[0050] Additionally, the second light source (122) may include a plurality of light sources arranged in a row. Accordingly, the second light-emitting region (132) may be referred to as a line light source. In one example, the second light-emitting region (132) may have a size corresponding to a plurality of pixels arranged in a row. In another example, the second light-emitting region (132) may have a size corresponding to a single pixel or a size corresponding to a plurality of pixels arranged in a matrix.

[0051] Additionally, the third light source (123) may include a plurality of light sources arranged in a matrix form. Accordingly, the third light-emitting region (133) may be referred to as a surface light source. In one example, the third light-emitting region (133) may have a size corresponding to a plurality of pixels arranged in a matrix. In another example, it may have a size corresponding to a single pixel.

[0052] The first light-emitting area (131), the second light-emitting area (132), and the third light-emitting area (133) may be partitioned by a partition wall (115). The partition wall (115) may be positioned on the outer edge surrounding each light-emitting area (130) and may not be located between a plurality of light sources (120) positioned within the light-emitting area (130).

[0053] Additionally, the partitions (115) may be spaced apart at different intervals on the substrate (110). Also, the area or size of the first light-emitting region (131), the second light-emitting region (132), and the third light-emitting region (133) may be different.

[0054] Accordingly, since the embodiment may be equipped with a point light source, a line light source, and a surface light source on a single substrate (110), it is possible to improve visibility when displaying images or information such as logos, symbols, or characters, and to provide various information by improving the degree of freedom, thus providing technical effects.

[0055]

[0056] FIG. 3 is a plan view of a lighting device according to an embodiment. Referring to FIG. 3, the lighting device (102) according to an embodiment may have a plurality of light-emitting regions (130). The lighting device (101) may have a plurality of light-emitting regions (130) arranged in a first direction (X) and a second direction (Y).

[0057] The plurality of light-emitting regions (130) may be arranged on the same substrate (see FIG. 2). The light-emitting region (130) may include a first light-emitting region (131), a second light-emitting region (132), and a third light-emitting region (133).

[0058] Additionally, the light source (120) may include a first light source (121) disposed within a first light-emitting region (131), a second light source (122) disposed within a second light-emitting region (132), and a third light source (123) disposed within a third light-emitting region (133). The first light source (121), the second light source (122), and the third light source (123) may include the same light source (LED), but are not limited thereto.

[0059] Meanwhile, each of the first light source (121), the second light source (122), and the third light source (123) may have a different number of light sources. At least one of the number of the first light source (121), the second light source (122), and the third light source (123) may be different.

[0060] For example, the first light source (121) placed within the first light-emitting region (131) may be one. Accordingly, the first light-emitting region (131) may be referred to as a point light source.

[0061] Additionally, the first light-emitting region (131) may be partitioned by a first partition (115-1). The first partition (115-1) may be positioned to surround the first light source (121).

[0062] A light source may be placed within the first light-emitting area (131) surrounded by the first partition (115-1).

[0063] Additionally, the second light source (122) of the second light-emitting region (132) may include a plurality of light sources. The second light source (122) may be arranged in the form of (m1 x n1) or (an integer greater than or equal to m1:1, n1:2). Accordingly, the second light-emitting region (132) may be referred to as a line light source or a line light source.

[0064] Additionally, the second light-emitting area (132) may be partitioned by a second partition (115-2). A second light source (122) may be arranged in a row within the second light-emitting area (132) enclosed by the second partition (115-2). Additionally, a partition may not be located between each of the second light sources (122).

[0065] Additionally, the light source of the third light-emitting region (133) can be arranged in the form of a matrix (m2 x n2), (m2: an integer greater than or equal to 2, n2: an integer greater than or equal to 2). Accordingly, the third light-emitting region (133) can be referred to as a surface light source.

[0066] Additionally, the third light-emitting region (133) may be partitioned by a third partition (115-3). Within the third light-emitting region (133) enclosed by the third partition (115-3), a third light source (123) may be arranged in multiple rows.

[0067] A partition wall may not be located between each of the above third light sources (123).

[0068] In one embodiment, the number of multiple second light sources (122) disposed within one second light-emitting region (132) and the number of multiple second light sources (122) disposed within another second light-emitting region (132) may be different from each other. Additionally, the number of multiple third light sources (133) disposed within one third light-emitting region (133) and the number of multiple third light sources (123) disposed within another third light-emitting region (133) may be different from each other.

[0069] In one embodiment, the spacing between a plurality of second light sources (122) arranged within one second light-emitting region (132) and the spacing between a plurality of second light sources (122) arranged within another second light-emitting region (132) may be different from each other. Additionally, the spacing between a plurality of third light sources (133) arranged within one third light-emitting region (133) and the spacing between a plurality of third light sources (123) arranged in another third light-emitting region (133) may be different from each other. Furthermore, the spacing between a plurality of second light sources (122) arranged within the second light-emitting region (132) and the spacing between a plurality of third light sources (133) arranged within the third light-emitting region (133) may also be different from each other.

[0070] In one embodiment, the diffusion layer (118) disposed on the first light-emitting region (131), the diffusion layer (118) disposed on the second light-emitting region (132), and the diffusion layer (118) disposed on the third light-emitting region (133) may each have the same or different thickness or diffusion agent content. That is, the thickness or diffusion agent content of each diffusion layer (118) may be implemented the same or different depending on the light-emitting region in which each is disposed.

[0071] When the first light-emitting area (131) and the second light-emitting area (132) are adjacent, the first partition (115-1) and the second partition (115-2) may share the same partition. Additionally, when the second light-emitting area (132) and the third light-emitting area (133) are adjacent, the second partition (115-2) and the third partition (115-3) may share the same partition. Additionally, when the third light-emitting area (133) and the first light-emitting area (131) are adjacent, the third partition (115-3) and the first partition (115-1) may share the same partition.

[0072] Accordingly, since the embodiment allows a point light source, a line light source, and a surface light source to be provided on a single substrate, it has the technical effect of improving visibility when displaying images or information such as logos, symbols, or characters, and improving degrees of freedom to provide various information.

[0073] Additionally, in the embodiment, each of the light-emitting regions (130) may have a flat plane in the shape of a polygon, such as a triangle or a square, or in the shape of a circle or an ellipse.

[0074] Accordingly, the embodiment can improve the design freedom of the lighting device as the light-emitting region (130) has various shapes, and has the technical effect of enabling optical design through shape control of the light-emitting region (130).

[0075] In one embodiment, the horizontal thickness of the partition wall (115) surrounding each of the light-emitting regions (130) may be implemented identically. Meanwhile, the present disclosure is not limited thereto, and the horizontal thickness of the partition wall (115) may be implemented differently depending on the type of light-emitting region (130) surrounding it. For example, the horizontal thickness of the partition wall (115) surrounding the first light-emitting region (131) may be thinner than the horizontal thickness of the partition wall (115) surrounding the second light-emitting region (132) or the third light-emitting region (133). Also, the horizontal thickness of the partition wall (115) surrounding the second light-emitting region (131) may be thinner than the horizontal thickness of the partition wall (115) surrounding the third light-emitting region (133).

[0076] Alternatively, the horizontal thickness of the partition wall (115) surrounding the first light-emitting area (131) may be thicker than the horizontal thickness of the partition wall (115) surrounding the second light-emitting area (132) or the third light-emitting area (133). And the horizontal thickness of the partition wall (115) surrounding the second light-emitting area (131) may be thicker than the horizontal thickness of the partition wall (115) surrounding the third light-emitting area (133).

[0077] As another example, the horizontal thickness of the partition wall (115) surrounding each of the light-emitting regions (130) may be the same or different depending on the region of the upper surface of the substrate. For example, in a first region of the upper surface of the substrate, the horizontal thickness of the partition wall (115) may have a first thickness, and in a second region of the upper surface of the substrate that is different from the first region, the horizontal thickness of the partition wall (115) may have a second thickness, and the second thickness may be different from the first thickness.

[0078] FIG. 4 is a diagram showing an example of operation of a lighting device according to an embodiment. First, referring to FIG. 4 (a), a plurality of light-emitting regions may be arranged within the lighting device. For example, the plurality of light-emitting regions may include a first region (141), a second region (142), and a third region (143).

[0081] The first area (141), second area (142), and third area (143) can be distinguished by the number or area of ​​partitions placed within the area.

[0082]

[0083] Also, referring to FIG. 4(b), in the lighting device according to the embodiment, for example, the first area (141) and the third area (143) can be turned on and the second area (142) can be turned off.

[0084] Additionally, for example, the first area (141) may be lit collectively or selectively. Additionally, the third area (143) may be lit in a line shape.

[0085] In addition, for example, the embodiments can be lit sequentially according to the position of the light-emitting area, and can implement a gradient-shaped lighting.

[0086] Additionally, the first area (141) and the third area (143) may be displayed in different colors. Accordingly, the embodiment can highlight information such as text or images provided through a lighting device, and has the technical effect of improving aesthetics.

[0087]

[0090] Accordingly, point light sources, line light sources, and surface light sources, each or a combination thereof, can display different information such as logos, symbols, characters, or images, and the light source can be selected to enhance visibility and aesthetics depending on the information displayed.

[0091] For example, in (a), the first light-emitting area (131) can function as a point light source to improve the visibility of the text being expressed, the second light-emitting area (132) can function as a line light source to improve the aesthetics of the design, and the third light-emitting area (133) can function as a surface light source to highlight the text provided to the first light-emitting area (131) or improve its aesthetics.
