[0026] The implementation and usage of the embodiments are discussed in detail below. However, it should be understood that the specific embodiments discussed herein are merely intended to illustrate specific ways of implementing and applying the present disclosure exemplarily, and are not intended to limit the scope of the present disclosure. When describing structural positions of various components, the direction-related expressions, such as upper, lower, top and bottom, are not absolute, but relative. When the components are arranged as shown in the drawings, these direction-related expressions are appropriate, but when the positions of these components in the drawings would be changed, these direction-related expressions should be changed accordingly.
[0027] In this context, the terms, such as "install", "connect" and "fix", should be understood in abroad sense unless otherwise specified and defined. For example, it may be fixed connection, detachable connection, or integration; it may be a mechanical connection, or an electrical connection; it may be a direct connection or an indirect connection via an intermediary; and it may be an internal communication of two components or an interaction relationship between two components. For those skilled in the art, specific meanings of the above terms in this context may be understood according to specific situations.
[0028] In this context, "front" and "rear" are relative to a front-rear direction of a travelingdirection of a vehicle. In addition, "longitudinal direction" refers to a direction in which the object has a relatively large dimension, also known as a length direction.
[0029] The vehicle usually uses a logo that can emit light to improve the aesthetics of the vehicle and provide safety for driving at night or in a dark light environment, and the luminous logo has a hollowed portion to transmit the light. The inventor has found that the light seen by the observer outside the luminous logo is not uniform and inconsistent at present, and light emitting elements can be directly seen at some angles, which reduces the user experience and driving safety.
[0030] FIGS. 1 to 7 show schematic views of a light emitting device and components thereof according to an embodiment of the present disclosure. The light emitting device 100 may be designed as a vehicle logo, and the configuration thereof may be changed according to the requirement of the vehicle logo, and is not limited to that shown in the drawings. The light emitting device 100 may be installed at front and / or rear of the vehicle, so that the light emitting device 100 generates a luminous effect toward the outside of the vehicle, for example, at hood, grille shutter, front bumper, trunk lid and the like of the vehicle, which is not limited herein.
[0031] As shown in FIG. 1 to FIG. 3, the light emitting device 100 comprises a housing 110 and a top cover 120 attached to the housing 110, and a plurality of light emitting elements 140 are accommodated in the housing 110. FIG. 3 shows ten light emitting elements 140 arranged at intervals along the periphery of the housing 110, and it may be understood that the number and arrangement of the light emitting elements 140 are not limited to those shown in the drawings, and may be changed as required. The top cover 120 of the light emitting device 100 is provided therethrough with a penetrating portion 121 with a preset shape for transmitting light, so that the light from each of the light emitting elements 140 is led out of the light emitting device 100. The penetrating portion 121 shown in FIG. 1 is provided at a substantially central position of the top cover 120 and has a preset shape comprising letters and patterns, and it may be understood that the preset shape of the penetrating portion 121 may be changed according to the requirement of the vehicle logo, and is not limited to that shown in the drawings.
[0032] When the light emitting elements 140 of the light emitting device 100 are switched on, the light from each of the light emitting elements 140 may be led out of the penetrating portion 121, so that a luminous effect in a form of the vehicle logo may be seen outside the lightemitting device 100. However, due to a non-uniform shape of the penetrating portion 121 and arrangement positions of the light emitting elements 140, when the light emitting device 100 is observed, it may be seen that, for example, weaker light is transmitted through a larger penetration area, and stronger light is transmitted through a smaller penetration area, and the light emitting elements 140 may also be directly seen, which reduces the user experience.
[0033] The present disclosure solves the above problems by providing a reflecting device 130 in the housing 110 for reflecting the light from the plurality of light emitting elements 140. Specifically, the reflecting device 130 is provided with a plurality of reflecting portions 131 respectively corresponding to each of the light emitting elements 140. FIG. 2 shows ten reflecting portions 131 respectively corresponding to ten light emitting elements 140, and each of the reflecting portions 131 covers at least a portion of each of the corresponding light emitting elements 140, so that the light from each of the light emitting elements 140 may be reflected by each of the reflecting portions 131 for many times in the light emitting device 100 and then led out of the light emitting device 100 via the penetrating portion 121. In this way, the light is uniformly distributed in the light emitting device 100 by using the reflecting device 130 for multiple reflections, so that the brightness of the light emitting device 100 is more consistent. Moreover, the reflecting device 130 also covers the light emitting elements 140, preventing the observer from directly seeing the light emitting elements 140 and the light emitted by the light emitting elements 140, thereby reducing the possibility of generating glare and bright spots and improving the user experience.
[0034] Referring to FIG. 3, the housing 110 of the light emitting device 100 comprises a bottom plate 111 and a side plate 112 attached to the bottom plate 111. The bottom plate I l l is provided thereon with a control plate component 150 electrically connected to each of the light emitting elements 140, and the control plate component 150 may be configured as a circuit board, so as to, for example, control switching on, switching off and / or light intensity of each of the light emitting elements 140 according to user requirements and / or environmental brightness. As such, the space in the light emitting device 100 may be fully utilized, the wiring length in the light emitting device 100 may be reduced, and the response speed may be improved.
[0035] Hereinafter, the configuration of the reflecting device 130 according to an embodiment of the present disclosure will be described in detail.
[0036] As shown in FIG. 2 and FIG. 4, each of the reflecting portions 131 of the reflecting device 130 is provided with a top wall 133 at a preset distance from inner side of the top cover 120, that is to say, provided with a top wall 133 at a preset distance from a side of the top cover 120 facing the light emitting elements 140, and each of the reflecting portions 131 of the reflecting device 130 is further provided with a side wall 132 abutting against the control plate component 150. In some embodiments, the shape of the side wall 132 of each of the reflecting portions 131 may be adapted to the shape of the side plate 112 of the housing 110. As such, the light emitting elements 140 may be covered, and it is also possible to enable the light emitted by the light emitting elements 140 to have more space to be reflected in the reflecting portions 131, thereby increasing the reflecting paths of the light in the reflecting portions 131 and making the light more uniformly distributed. It should be understood that the preset distance varies depending on the structure of the light emitting device 100, which is not limited herein.
[0037] As shown in FIG. 4, in this embodiment, the top wall 133 of each of the reflecting portions 131 has a planar shape, and the side wall 132 thereof has a curved shape, so as to achieve coverage of the light emitting elements 140 and multiple reflections of the light therefrom. It may be understood that the shape of the top wall 133 and / or the side wall 132 of each of the reflecting portions 131 is not limited thereto, and may be changed as required. For example, the top wall 133 and / or the side wall 132 of each of the reflecting portions 131 may have curved shape, planar shape, combination of curved shape and curved shape, combination of planar shape and planar shape and the like. In addition, it may be seen from FIG. 4 that each of the reflecting portions 131 may adaptively have different shapes and sizes according to the structure of the light emitting device 100.
[0038] As shown in FIG. 2, FIG. 3 and FIG. 6, the reflecting device 130 is provided with at least one mounting portion 134 at the periphery thereof, and the bottom plate 111 of the housing 110 is provided with at least one mounting hole 113 corresponding to the mounting portion 134, so as to fix the reflecting device 130 to the housing 110. The mounting portion 134 is provided at the periphery of the reflecting device 130, which facilitates the alignment of the reflecting device 130 and the housing 110 without affecting the reflecting function of the reflecting portions 131, thereby reducing the installation time and complexity of the reflecting device 130. In this embodiment, the reflecting device 130 comprises three mounting portions 134 provided at two ends of the reflecting device 130 in the longitudinal direction andconfigured as through holes. It may be understood that the number and arrangement of the mounting portions 134 are not limited thereto, and may be changed as required. In FIG. 6, the reflecting device 130 is fixed to the housing 110 by a fastening bolt 160. It may be understood that the fixing manner of the reflecting device 130 is not limited thereto, and the reflecting device 130 may also be fixed by using, for example, fastening pin, buckle and the like.
[0039] As shown in FIG. 3 and FIG. 5 to FIG. 7, the reflecting device 130 is provided with at least one attaching portion 135 at the periphery thereof, and the control plate component 150 is provided with at least one attaching hole 151 corresponding to the attaching portion 135, so as to attach the reflecting device 130 to the control plate component 150. In FIG. 5, the attaching portion 135 is configured as a pillar projecting from the reflecting device 130 toward the control plate component 150, and the pillar is inserted into the attaching hole 151 of the control plate component 150, so as to attach the reflecting device 130 with the control plate component 150 together. In FIG. 6, the bottom plate 111 of the housing 110 may be provided thereon with a plurality of support portions 114 corresponding to the control plate component 150, and each of the support portions 114 may be configured to project toward the control plate component 150 from the bottom plate 111, so as to support the control plate component 150. As such, the number of bored holes on the control plate component 150 may be reduced, and the strength of the control plate component 150 may be ensured, so that when the control plate component 150 is a circuit board with lower strength, the phenomena such as its breakage may be reduced.
[0040] Additionally, in some embodiments, an inner wall of each of the reflecting portions 131 of the reflecting device 130 may be coated with, for example, silver-plated coating, aluminum-plated coating or white coating and the like, and the inner wall here is a side of each of the reflecting portions 131 facing the light emitting elements 140, wherein the white coating may be, for example, white silica gel coating, white ceramic coating or white polyester coating and the like. In this way, the reflectivity of each of the reflecting portions 131 may be improved, so as to ensure that the loss of light is minimized when the light is reflected for many times in the reflecting portions 131, thereby further improving the luminous effect of the light emitting device 100.
[0041] According to the present disclosure, the reflecting device is provided in the light emitting device for covering the light emitting elements and reflecting the light from the light emitting elements for many times in the light emitting device, so that the light emitted by thelight emitting elements may be uniformly distributed in the light emitting device, and the observer is prevented from directly seeing the light emitting elements and the light emitted by the light emitting elements, thereby improving the luminous effect of the light emitting elements and further improving the user experience.
[0042] It should be understood that the embodiments shown in the drawings only illustrate the optional shape, size and arrangement of the light emitting device according to the present disclosure.
