Technical Field
[0001] Embodiments of this disclosure generally relate to the field of lighting and / or signal indication, and more specifically, to lighting devices and motor vehicles capable of providing replaceable desiccant assemblies and equipped with such replaceable desiccant assemblies. Background Technology
[0002] Lighting devices provide light for illumination and / or optical indication functions, and are widely used in various fields, such as in motor vehicles where lighting devices like headlights ensure safe driving. During use, lighting devices often encounter the problem of moisture condensation, forming humidity inside their housings. If excessive moisture inside the housing is not removed in a timely manner, the electrical components inside the housing are highly likely to be damaged.
[0003] In the industry, the conventional approach to address the aforementioned issues is to place a desiccant inside the casing to absorb excess moisture. However, in some existing technologies, the desiccant inside the casing is irreplaceable; that is, once the desiccant reaches saturation with moisture, it loses its dehumidifying function.

[0018] Figure 1 This is an exploded view schematically illustrating a replaceable desiccant assembly according to an exemplary embodiment of the present disclosure;
[0019] Figure 2 This is a schematic diagram illustrating a lamp device having a replaceable desiccant assembly according to an exemplary embodiment of the present disclosure;
[0020] Figure 3 This is an exploded view illustrating the structure of a replaceable desiccant assembly according to another exemplary embodiment of the present disclosure;
[0021] Figure 4 This is a cross-sectional view illustrating the structure of a replaceable desiccant assembly according to another exemplary embodiment of the present disclosure. Detailed Implementation
[0022] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. In this specification, identical or similar components are indicated by identical or similar reference numerals. The following description of embodiments of this disclosure with reference to the accompanying drawings is intended to explain the overall concept of this disclosure and should not be construed as a limitation thereof.
[0023] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of embodiments of the present disclosure. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.
[0024] Figures 1 to 4 A replaceable desiccant assembly 10 is schematically shown according to an exemplary embodiment of the present disclosure. Figure 2 This is a schematic diagram illustrating a lamp device with a replaceable desiccant assembly according to an exemplary embodiment of the present disclosure. Figure 2 As shown, the replaceable desiccant assembly 10 is disposed on the back side of the lamp device 20 opposite to the lens emission direction 30. In some embodiments, the main body of the replaceable desiccant assembly 10 is located outside the lamp device 20, thereby achieving better dehumidification without occupying internal space of the lamp device.
[0025] Figure 1 This is an exploded view schematically illustrating a replaceable desiccant assembly according to an exemplary embodiment of the present disclosure. Figure 1 As shown, the replaceable desiccant assembly 10 includes a housing 110 configured with an opening and a cavity for containing desiccant. The housing 110 is detachably attached to the housing of the lamp device. The replaceable desiccant assembly 10 also includes a cover 130 that covers the opening of the housing and is configured to include at least one hole 132 communicating with the interior of the lamp device. After being attached to the lamp device housing, the main body of the desiccant-containing cavity is located outside the lamp device and directly contacts and dehumidifies the air inside the lamp device through the hole 132 communicating with the interior of the lamp device. In some embodiments, such as Figure 1 As shown, the replaceable desiccant assembly 10 also includes a sealing element 120, which is disposed at the attachment structure of the housing to the housing of the lamp device. The sealing element may be, for example, a sealing ring, so that the housing can be sealed to the housing of the lamp device 10.
[0026] The receiving housing 110 of the replaceable desiccant assembly 10 includes one or more partitions 114 configured such that a desiccant can be attached to its surface. The partitions 114 increase the area within the receiving housing where a desiccant pack can be attached. In some embodiments, the desiccant is a packaged desiccant, which is adhered to the inner surface of the receiving housing and the surfaces of the partitions. In some embodiments, the receiving housing 110 is integrally formed with one or more partitions 114. Figure 1The illustration shows a housing 110 containing a partition 114. In some embodiments, multiple partitions 114 may be included to increase the area available for attaching desiccant packets. In some embodiments, the partitions 114 are arranged perpendicular to the opening plane of the housing to maximize the area available for attaching desiccant packets.
[0027] Those skilled in the art should understand that the dehumidification efficiency of desiccant is related to the contact area between the desiccant and the gas to be dehumidified. Therefore, the arrangement of the partition 114 allows more desiccant packets to be laid flat on both sides of the partition, significantly increasing the dehumidification efficiency of the removable desiccant assembly. Of course, the arrangement of the desiccant is not limited to this; any desiccant, with or without packaging, can be placed in the housing.
[0028] Figure 3 This is an exploded view schematically illustrating a replaceable desiccant assembly according to another exemplary embodiment of the present disclosure. Figure 4 This is a cross-sectional view illustrating the structure of a replaceable desiccant assembly according to another exemplary embodiment of the present disclosure.
[0029] like Figure 3 As shown, one or more partitions 218 are detachably mounted on the housing 1. Correspondingly, the housing 210 is configured to include a mounting structure 217 that mates with the partitions 218, which may be, for example, a slot. According to the above embodiment, the partitions can be selectively installed / removed to meet different desiccant / desiccant pack installation and dehumidification requirements. Figure 4 As shown, the mounting structure 217 is spaced apart from the bottom plane of the housing, thereby leaving space at the bottom of the housing to accommodate the desiccant pack attached to the bottom of the housing, so as to maximize the use of all the space of the housing 210 of the removable desiccant assembly 10.
[0030] Embodiments of this disclosure also provide motor vehicles that include replaceable desiccant assemblies or lighting devices as described in any of the foregoing embodiments.
[0031] Although this disclosure has been described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to illustrate preferred embodiments of this disclosure and should not be construed as limiting the disclosure. The dimensions in the drawings are merely illustrative and should not be construed as limiting the disclosure.
[0032] While some embodiments of the general concept of this disclosure have been shown and described, those skilled in the art will understand that changes may be made to these embodiments without departing from the principles and spirit of the general concept of this disclosure, the scope of which is defined by the claims and their equivalents.
