Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tunnel lighting technology, and in particular relates to a dustproof tunnel light. Background Technology
[0002] Tunnel lighting is a core facility for ensuring driving safety, especially in one-way highway tunnels where traffic volume is high and vehicle speeds are fast, generating a lot of dust. This scenario places extremely high demands on the reliability of lighting fixtures. Currently, most mainstream tunnel lighting fixtures adopt a fully sealed structure design, which effectively blocks dust, but severely limits heat dissipation, making the fixtures prone to overheating and damage.
[0003] Therefore, how to improve the heat dissipation efficiency of lamps while maintaining their dustproof function in one-way highway tunnels is a technical problem that urgently needs to be solved by those skilled in the art.
[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0006] In a first aspect, embodiments of this disclosure provide a dustproof tunnel light, comprising:
[0007] A sealed housing, which contains a power supply unit and a light source unit, the power supply unit and the light source unit being connected by a mounting post;
[0008] The outer casing is fitted over the sealed housing;
[0009] The heat dissipation assembly includes several large heat sinks disposed on the outer wall of the sealed housing;
[0010] The outer casing has an air inlet and an air outlet on its front and rear sides, respectively. The air inlets and outlets are positioned correspondingly, and the area of the air inlet is larger than the area of the air outlet.
[0011] The adjacent large heat sinks are arranged in a figure-eight shape, and the gaps formed by the adjacent large heat sinks form an airflow channel with the air inlet and air outlet. The direction of the airflow in the airflow channel is consistent with the driving direction in the tunnel.
[0012] In one optional embodiment, at least one small heat sink is further provided in the airflow channel, the height of the small heat sink being less than the height of the large heat sink.

[0014] In one optional embodiment, the bottom surface of the sealing housing is a transparent ceramic base plate, and the substrate is assembled onto the transparent ceramic base plate by sealing bolts.
[0015] In one alternative embodiment, the side plates on both sides of the housing are detachably mounted to the housing body by locking bolts.
[0016] In one alternative embodiment, a pair of pins are provided on both sides of the sealing housing, and a pin sleeve adapted to the pins is provided on the side plate.
[0017] Secondly, embodiments of this disclosure also provide a dustproof tunnel light, comprising:
[0018] Sealed housing;
[0019] The outer casing is fitted over the sealed housing;
[0020] The heat dissipation assembly includes several large heat sinks disposed on the outer wall of the sealed housing;
[0021] The outer casing has an air inlet and an air outlet on its front and rear sides, respectively, and the air inlets and outlets are positioned correspondingly; and,
[0022] The large heat sink extends along the tunnel's travel direction and forms a gap with each other. This gap, together with the air inlet and air outlet, forms an airflow channel that gradually narrows from the air inlet to the air outlet.
[0023] In one alternative embodiment, adjacent large heat sinks are arranged in a figure-eight pattern to form a directional airflow channel; and,
[0024] The wide opening of the airflow channel is connected to the air inlet, and the narrow opening of the airflow channel is connected to the air outlet.

[0026] The beneficial effects of this utility model are that the power supply and light source of this dustproof tunnel light are set in a sealed housing, which can effectively block dust; the outer wall of the sealed housing is provided with a heat dissipation component, which forms a figure-eight-shaped tapering airflow channel with the air inlet and air outlet on the housing. The tapering airflow channel can accelerate the airflow speed in the channel; in addition, the wind generated by the traffic flow in the tunnel enters the airflow channel, which further accelerates the airflow in the airflow channel, thereby quickly removing the heat emitted by the heat dissipation component and improving the heat dissipation efficiency of the tunnel light.

[0042] Research has revealed the shortcomings of existing technologies: Currently, most mainstream tunnel lighting fixtures adopt a fully sealed structure design, which effectively blocks dust but severely limits heat dissipation capacity, making the fixtures prone to overheating and damage.
[0043] Based on the above research, this disclosure provides a dustproof tunnel light that uses a sealed housing to block dust and a heat dissipation component to form an airflow channel. The airflow generated by the traffic flow in the tunnel is introduced into the airflow channel to quickly remove the heat from the heat dissipation component, thereby preventing the light from overheating and being damaged.
[0044] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.
[0045] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0046] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0047] See Figure 1 This disclosure provides a dustproof tunnel light, including: a sealed housing 100, within which a power supply unit 110 and a light source unit 120 are disposed. The power supply unit 110 and the light source unit 120 are connected by a mounting post 130. A power cord interface is pre-embedded on the side of the sealed housing 100, and the power supply unit 110 is connected to an external power source through the power cord interface. The power supply unit 110 and the light source unit 120 are the core components of the light fixture, and their placement within the sealed housing 100 can block dust.
[0048] See Figure 1 and Figure 2 The sealed housing 100 is fitted with an outer shell 200, and the front and rear sides of the outer shell 200 are respectively provided with an air inlet 210 and an air outlet 220. A heat dissipation assembly 300 is also provided on the outer wall of the sealed housing 100. The heat dissipation assembly 300 includes several large heat dissipation fins 310 disposed on the outer wall of the sealed housing 100. Adjacent large heat dissipation fins 310 are arranged in a V-shape, and the gaps formed by adjacent large heat dissipation fins 310, together with the air inlet 210 and the air outlet 220, form an airflow channel 400. The airflow channel 400 formed by the V-shaped arrangement of large heat dissipation fins 310 is gradually narrowing. When the airflow passes through this gradually narrowing airflow channel 400, it can accelerate its flow speed, thereby quickly carrying away the heat on the large heat dissipation fins 310. Preferably, the direction of airflow within the airflow channel 400 is consistent with the direction of vehicle traffic within the tunnel, such as... Figure 2 As indicated by the arrows: F1 represents the airflow direction within airflow channel 400, and F2 represents the vehicle travel direction within the tunnel. The wind generated by the traffic flow within the tunnel enters airflow channel 400, further accelerating airflow and improving the heat dissipation efficiency of the tunnel lights.
[0049] See Figure 1 and Figure 2 In some embodiments, at least one small heat sink 320 is also provided in the airflow channel 400. The height of the small heat sink 320 is less than the height of the large heat sink 310, so that the three sides of the small heat sink 320 can fully contact the air in the airflow channel 400, thereby increasing the heat exchange area between the sealed housing 100 and the outside air.
[0050] See Figure 3 In some embodiments, the light source 120 includes a substrate 121 and a plurality of lamp beads 122. The lamp beads 122 are arranged in an array on the substrate 121 so that the heat emitted by the lamp beads 122 is evenly transferred to the heat sink, avoiding heat concentration in one place and causing local overheating.
[0051] See also Figure 3 In some embodiments, the bottom surface of the sealed housing 100 is a transparent ceramic base plate 140, and the substrate 121 is assembled onto the transparent ceramic base plate 140 by sealing bolts 141. Compared with ordinary tempered glass, the transparent ceramic base plate 140 has stronger thermal conductivity, which is beneficial to improving the overall heat dissipation efficiency of the tunnel light.
[0052] See Figure 4In some embodiments, the side plates 230 on both sides of the outer casing 200 are detachably mounted to the outer casing 200 housing via locking bolts 231. A pair of pins 150 are provided on both sides of the sealing casing 100, and pin sleeves 232 adapted to the pins 150 are provided on the side plates 230. During tunnel light installation, simply insert the pins 150 into the pin sleeves 232 to fix the sealing casing 100 in the outer casing 200, then tighten the locking bolts 231 to fix the side plates 230 to both sides of the outer casing 200, thus completing the installation; the operation is simple.
[0053] See Figure 1 and Figure 2 This disclosure also provides a dustproof tunnel light, including: a sealed housing 100; an outer shell 200, which is sleeved on the outside of the sealed housing 100; and a heat dissipation assembly 300, including a plurality of large heat dissipation fins 310 disposed on the outer wall of the sealed housing 100. The outer shell 200 has an air inlet 210 and an air outlet 220 respectively disposed on its front and rear sides, with the air inlet 210 and air outlet 220 being positioned correspondingly. The large heat dissipation fins 310 extend along the tunnel's driving direction, and adjacent large heat dissipation fins 310 form gaps, which, together with the air inlet 210 and air outlet 220, form an airflow channel 400, which gradually narrows from the air inlet 210 to the air outlet 220.
[0054] See Figure 1 and Figure 2 In some embodiments, adjacent large heat sinks 310 are arranged in a figure-eight shape to form a directional airflow channel 400; the wide opening of the airflow channel 400 is connected to the air inlet 210, and the narrow opening of the airflow channel 400 is connected to the air outlet 220.
[0055] In summary, this dustproof tunnel light houses the power supply unit 110 and the light source unit 120 within the sealed housing 100, effectively blocking dust. The outer wall of the sealed housing 100 is equipped with a heat dissipation component 300, which, together with the air inlet 210 and air outlet 220 on the outer housing 200, forms a V-shaped, tapering airflow channel 400. This tapering airflow channel 400 accelerates the airflow within the channel. Furthermore, the wind generated by the traffic flow within the tunnel enters the airflow channel 400, further accelerating airflow and quickly carrying away the heat emitted by the heat dissipation component 300, thus improving the heat dissipation efficiency of the tunnel light.
[0056] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0057] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0058] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0059] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0060] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
