An accommodating space is formed in the housing 010, and the light guide element 020 and the light source 030 are both disposed in the accommodating space, and the light emitted from the light source 030 needs to be emitted from the light opening 011 in the housing 010 under the conduction of the light guide element 020. The device can be used for combined contour lighting and ambient lighting of a motor vehicle interior. The light guide elements 020 currently used in the market are mainly two types:

one is a double-component light guide, consisting of a transparent light guide 021 and a diffuse light guide 022, as shown in fig. 1. The light emitted from the light source 030 is incident from the light incident surface of the transparent light guide 021, propagates through the transparent light guide 021, is incident into the diffusing light guide 022, and is then emitted from the light emitting surface of the diffusing light guide 022 to the light opening 011. The light guide is usually made of a high polymer material, such as optical grade plastic, which has a small selection range and high price, and the double-component light guide is usually manufactured by adopting a double-color injection molding process, so that the manufacturing process is complex and the cost is high.

The other is to add a diffuse light guide to the mirror group 023, and a light guide channel is formed between the two mirrors, and the diffuse light guide is disposed between the outlet of the light guide channel and the light opening 011 of the housing 010, as shown in fig. 2. The light emitted from the light source 030 is incident from the entrance of the light guide channel, reflected by the two reflectors, incident into the diffuse light guide from the exit of the light guide channel, and then emitted from the light emitting surface of the diffuse light guide 022 to the light opening 011. The reflecting mirror is made of non-transparent materials, the reflecting surface of the reflecting mirror is required to be provided with small grain textures to form diffuse reflection, and the reflecting surface of the reflecting mirror is provided with a reflecting metal layer or is directly made of white materials with high reflectivity. The number of the parts of the light guide element is large, the assembly is complex, and the cost is high.

The two optical systems only transmit light emitted from the light source to the light port in a certain fixed light channel mode, the effective utilization rate of the light is low, the required installation space is large, the product size can only be installed at a large space position such as an instrument desk, and the product size is not beneficial to popularization and use of the product in a small space position such as a door plate and an AB column in a whole vehicle factory.

After the first housing 120 and the second housing 130 are fixedly connected, the accommodating cavity 140 is formed therebetween. The first housing 120 and the second housing 130 may be fixed and connected by welding, gluing, riveting, or fixing members or structures such as screws, buckles, etc. An interval is formed between one end of the second housing 130 and the first housing 120, so as to form a light outlet 160 communicating with the accommodating cavity 140. Of course, the above is only a preferred embodiment, in other embodiments, the first housing 120 and the second housing 130 may be tightly and fixedly connected, and the light outlet 160 may be disposed on the first housing 120, the second housing 130, or a connection between the first housing 120 and the second housing 130. In another embodiment, the housing 100 may be a single housing structure or may be formed by combining more housings, and the housing 100 is a relatively conventional component and may be flexibly configured according to needs during implementation, so that details are not repeated herein.

The accommodating cavity 140 is provided with a reflective surface 110 for restricting light entering and exiting. The length direction of the light reflecting surface 110 is identical to the length direction of the light outlet 160. A light reflecting cavity 150 is formed between the light reflecting surface 110 and the housing 100, and the light outlet 160 is communicated with the light reflecting cavity 150. The radial cross-sectional profile of the reflecting surface 110 is at least partially an elliptical arc segment, the light emitting element 210 of the light emitting device 200 is disposed at the first focal point 111 of the ellipse where the elliptical arc segment is located, the irradiation direction of the light emitting element 210 faces the reflecting surface 110, and at least one light outlet 160 is disposed at the second focal point 112 of the ellipse where the elliptical arc segment is located or near the second focal point 112. When the light outlet 160 is disposed near the second focal point 112, the light outlet 160 is preferably not more than 1cm, more preferably not more than 5mm, from the second focal point 112. As shown in fig. 3 to 5, a preferred embodiment is schematically shown, that is, a reflecting device 300 is disposed in the accommodating cavity 140, and the reflecting device 300 has a strip shape, and the length direction of the reflecting device is consistent with the length direction of the light outlet 160. And the reflecting surface 110 is disposed at one side of the reflecting means 300.

The reflecting surface 110 is arranged on one side of the reflector. The radial cross-section profile of the reflecting surface 110 is an elliptical arc shape, which utilizes the optical characteristics of elliptical bifocal, that is, the light emitting point and the light emitting point are respectively disposed at two focuses of the elliptical arc-shaped reflecting surface 110, as shown in fig. 6, so as to ensure that most of the light is reflected to the light emitting opening 160, thereby effectively reducing energy consumption, improving the light utilization rate and improving the light efficiency. Of course, the shape of the reflecting surface 110 is not limited to the above, and in the specific implementation, when the brightness of the light emitting element 210 is sufficient, only a part of the radial cross-sectional profile of the light emitting element may be an elliptical arc segment, and the other part may be a straight line segment, an arc segment, a combination segment formed by a straight line segment and a straight line segment, a combination segment formed by an arc segment and an arc segment, or other shape segments. In other embodiments, the reflective surface 110 may be disposed on the inner wall of the housing 100, that is, the inner wall surface of the housing 100, such as the inner wall surface of the first housing 120 shown in fig. 4, is used as the reflective surface 110, and this design may be applied to an atmosphere lamp product with a smaller space, so that the product may be loaded on a smaller space of the vehicle body.

In a further embodiment, the ellipse in which the elliptical arc section is located, preferably has a major axis at least twice, more preferably three times or more than a minor axis, may enable the light-reflecting surface 110 to have a long and flat shape, i.e. the reflecting device 300 or the housing 100 may be designed to be flatter, so that it may be suitable for being installed in a door panel, an AB pillar, or an instrument desk having a severe size, which is narrow and deep in space.

In further embodiments, the light reflecting surface 110 may be designed as a smooth surface according to the light emitting requirement, or an optical pattern may be disposed on the light reflecting surface 110. The reflecting device 300 or the housing 100 for forming the reflecting surface 110 is made of a non-transparent material, i.e. completely opaque, and the reflecting surface 110 may be a reflecting metal layer, such as a metal layer of aluminum or chromium, obtained on one side of the reflecting device 300 or on the inner wall of the housing 100 by a spraying process or an electroplating process; it is also possible to set the inner wall of the housing 100 or the side of the reflecting means 300 to be white, for example, the reflecting means 300 or the housing 100 may be directly made of a white material with high reflectivity, etc.

It should be noted that the number of the light outlet 160 on the housing 100 is not limited to one, and may be a plurality of light outlets, and the positions of the light outlets 160 are not limited except for the light outlet 160 disposed at the second focal point 112 of the ellipse where the elliptical arc section is located or near the second focal point 112, and may be designed according to the requirement. The size of the light outlet 160 and the distance between the light emitting element 210 and the light outlet 160 can be adjusted according to the optical effect.

In a further embodiment, the light emitting device 200 preferably further includes a light emitting element carrier 220, and the light emitting element 210 is disposed on the light emitting element carrier 220, as shown in fig. 3 and 4. The light emitting member carrier 220 is preferably elongated, and the length direction thereof is consistent with the length direction of the light outlet 160. The number of the light emitting elements 210 is at least one, and when the number of the light emitting elements 210 is plural, the light emitting elements 210 are distributed along the length direction of the light emitting element carrier 220, and the light emitting direction of the light emitting elements 210 faces the light reflecting surface 110. The light reflecting member carrier may be a whole carrier or may be a combination of a plurality of carriers distributed along the length direction of the light outlet 160. One or more light emitting elements 210 are disposed on the carrier plate. The light emitting member 210 is preferably a light emitting diode, and in the case where a plurality of light emitting diodes exist, the light emitting diodes are physically and electrically connected. For example, the carrier board is preferably a circuit board, the light emitting diodes are arranged on the circuit board, and the light emitting diodes are electrically connected through the circuit board. The leds may be illuminated by the same color or different colors. The plurality of light emitting diodes may produce mixed light, such as mixed white light.

In the above embodiment in which the reflecting device 300 is provided, the light emitting element carrier 220 is preferably fixedly connected to the reflecting device 300, for example, the light emitting element carrier may be positioned and fixedly connected by a fixing element or structure such as welding, gluing, riveting, or a screw, a buckle, etc., so as to ensure that the center of the light emitting element 210 is located on the first focal point 111 of the light reflecting surface 110. The sub-assembly formed by the reflecting device 300 and the light emitting device 200 is preferably fixedly connected with the second housing 130, or the reflecting device 300 is fixedly connected with the second housing 130, or the light emitting element carrier 220 is fixedly connected with the second housing 130, and the fixing manner is, for example, positioning and fixing connection can be performed through welding, gluing, riveting or through fixing pieces or structures such as screws, buckles, etc., so that the light emitting part is located on the second focal point 112 of the light reflecting surface 110. The reflecting device 300 preferably adopts a plurality of reflective mirrors for combination and splice, and the light emitting element carrier 220 also adopts a plurality of carrier plates for combination and splice, and the carrier plates are arranged in a one-to-one correspondence with the reflective mirrors. The existing circuit board preparation capability is limited, and the production requirement of a longer circuit board cannot be met, so that if a specific design is adopted, if a required carrier board is longer, the current market production capability can only be obtained by adopting a mode of combining and splicing a plurality of shorter circuit boards. Of course, the carrier may be a whole circuit board when the market production capacity can meet the production requirements. However, as the length of the circuit board increases, the production cost and tolerance thereof become correspondingly large, and the reflection device 300 is also formed. Therefore, the length of the reflector and the circuit board can be shortened by adopting a combined splicing mode, so that the production cost and the tolerance can be effectively reduced. And each reflector and each circuit board can be independently installed, so that the installation precision between the reflector and the luminous piece 210 can be better controlled, and the uniformity and the brightness of the emergent light can be effectively improved. Of course, the above is only a preferred embodiment, and in the implementation, the reflecting device 300 and the light-emitting element carrier 220 may be both integrated structures, or may be both combined and spliced structures, or may be one integrated structure and the other combined and spliced structure.

Since the light-emitting element 210 is disposed at the first focal point 111 of the ellipse where the elliptical arc segment is located, the light emitted from the light-emitting element 210 will be reflected toward the second focal point 112 when it is directed toward the reflective surface 110 of the elliptical arc segment.

In a further embodiment, the light outlet 160 is preferably provided with a light outlet 400 for diffusing light, and the light outlet 400 is transparent or partially transparent. As shown in fig. 3 and 4, the light-emitting portion 400 is preferably formed in a long-strip shape, and has a length direction which matches the length direction of the light-emitting opening 160 and is disposed to cover the inner opening side of the light-emitting opening 160. The light emitting portion 400 is preferably fixedly connected to the second housing 130, for example, by welding, gluing, riveting, or fixing by a screw, a buckle, or other fixing members or structures. The inner side of the light-emitting portion 400, i.e. the side facing away from the light-emitting opening 160 is the light-entering side 410. The outer side of the light-emitting portion 400, that is, the side facing the light-emitting opening 160 is the light-emitting side thereof. The light-emitting part 400 is preferably a transparent diffuse light-emitting part, i.e., it is made of a colorless transparent diffusion material. In this embodiment, it is preferable that the light entrance side 410 of the light exit portion 400 is disposed at the second focal point 112, and at least part of the light emitted toward the second focal point 112 in the accommodating cavity 140 can pass through the light exit portion 400 and exit from the light exit 160. Of course, the light-entering side 410 of the light-emitting portion 400 may be disposed near the second focal point 112, and the light-entering side 410 is preferably not more than 1cm, more preferably not more than 5mm, from the second focal point 112. In addition, the light-emitting portion 400 is not limited to the above-mentioned one, for example, the light-emitting portion 400 may be a partially transparent diffuse light-emitting portion, that is, it is made of a partially transparent diffuse material; for example, one or more of scattering particles, air holes, textures, and the like may be provided on the light emitting portion 400. The texture may be, for example, a leather texture, an optical pattern, or the like, and is disposed on the light entrance side 410 or the light exit side of the light exit part 400, so as to achieve a desired optical effect.

The angle between the normal of the light-emitting element carrier 220 and the normal of the light-entering side 410 of the light-emitting portion 400 is 0 ° to 180 °. In order to mix light fully, such as RGB three-color mixing, most of the light emitted by the light emitting element 210 is prevented from directly reaching the light outlet 160, and to effectively improve the light efficiency, most of the light can be reflected to the position of the light outlet 160, an angle between a normal direction of the light emitting element carrier 220 and a normal direction of the light inlet side 410 of the light outlet 400 is preferably 60 ° to 120 °, and more preferably 75 ° to 105 °.

In a further preferred embodiment, an angle between a normal direction of the light emitting element carrier 220 and a normal direction of the light entrance side 410 of the light exit portion 400 is a-30 ° to a+30°, and when the angle is a°, a light ray emitted by the light emitting element 210 along the normal direction of the light emitting element carrier 220 after being reflected by the light reflecting surface 110 can pass through the second focal point 112 and be parallel to the normal direction of the light entrance side 410 of the light exit portion 400, that is, assuming that the light emitting element carrier 220 is disposed at the position a, an angle between the normal direction of the light emitting element carrier 220 and the normal direction of the light entrance side 410 of the light exit portion 400 is a-30 ° and a+30°, and when the light ray reflected by the light reflecting surface 110 passes through the second focal point 112 and is parallel to the normal direction of the light entrance side 410 of the light emitting element carrier 220, the light emitting element carrier 220 can be disposed at an angle between the normal direction of the light exit portion 220 and the light entrance side 410 a-30 ° to a+30°. In the above range, most of the light can exit from the light reflecting surface 110 at a smaller angle range relative to the normal line of the light incident side 410 of the light emitting portion 400, so as to further enhance the light efficiency.

The above arrangement of the light emitting unit 400, the light emitting device 200, the reflecting device 300, or the housing 100 is merely a preferable embodiment, and the arrangement of the respective components may be flexibly selected according to the need in the specific implementation, so long as the relative positions of the light emitting unit 200, the light emitting unit 400, and the reflecting surface 110 can be fixed and the positions of light incident and light emitting can be ensured by material fitting, force fitting, or integration. For example, the light emitting part 400 may be formed as a double-component case with the housing 100, such as the first case 120 or the second case 130, by using a two-shot molding process. The dual component housing has an opaque housing portion made of a non-transparent colored material and a transparent or partially transparent light exit portion 400. The outer surface of the shell part can be sprayed with liquid solvents with different colors according to the requirements of interior decoration colors, luster and the like. The spraying material can be transparent solvent or non-transparent colored solvent, or can be formed by multi-layer spraying combination of transparent solvent, non-transparent colored solvent and the like. By integrating the light-emitting unit 400 with the housing 100, it is possible to ensure an accurate and secure connection between the light-emitting unit 400 and the housing 100 while reducing the processing cost and the man-hour for installation. For another example, the light-emitting portion 400 may be fixedly connected to the reflecting device 300, and then fixedly connected to the housing 100, such as the first housing 120 or the second housing 130, in a sub-assembly manner. For another example, the housing 100, such as the first housing 120, and the reflective device 300 may be formed as a dual assembly, and then integrated by a two-shot molding process or some other process.

Compared with the prior art, the single reflection type atmosphere lamp has at least one or more of the following beneficial effects:

the single reflection type atmosphere lamp of the application abandons a high polymer light guide and a complex double-piece reflector light channel, and can achieve the channel light effect only by arranging one reflecting surface 110; the single reflection surface 110 is adopted to change the original fixed optical path into open, so that the design is more flexible; the design of the single reflecting surface 110 can fully mix the polychromatic light emitted by the light emitting element 210 in the open space to realize uniform light with any color; the single reflection surface 110 design can reduce the number of parts of the atmosphere lamp, reduce the cost and simplify the assembly process; the design of the single reflecting surface 110 can ensure that the light inlet and the light outlet 160 of the light guide channel are free from size constraint, and the optical path length is short and can be flexibly designed; the reflecting surface 110 uses the elliptic double-focus optical characteristic in physics, that is, the light emitted by one focus is reflected by the ellipse and is converged on the other focus, so that the light utilization rate can be effectively improved.
