[0040] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0041] Reference Figure 1 and Figure 2 As shown, the present invention provides a lighting device for a port, including a lamp housing 001 with an internal seal, the lamp housing 001 is a detachable structure up and down, which is convenient for placing and installing components such as a lamp panel, and a cover plate 002 installed on the lamp housing 001 and made of a round transparent material; the light generated by the components in the lamp housing 001 after being powered on can be emitted from the cover plate 002 and illuminate the ground or facilities, which is a well-known technology and will not be described in detail;

[0042] The difference is that, Figure 1 , Figure 3 and Figure 5 As shown, it also includes a ventilation pipe 100 of a tubular structure with two ends opened. The ventilation pipe 100 can be a copper heat exchange pipe, which is used to conduct the heat generated inside the lamp housing 001 to the outside of the lamp housing 001 to form a heat exchange and heat dissipation effect; the ventilation pipe 100 is horizontally inserted into the interior of the lamp housing 001, and multiple ventilation pipes 100 are distributed around the circumference; the multiple ventilation pipes 100 are perpendicular to the central axis of the lamp housing 001, and the multiple ventilation pipes 100 are located at the intersection inside the lamp housing 001 to form a mutually connected state (such as Figure 5 As shown), in order to enhance the heat dissipation effect of the lamp housing 001, the number of the circumferentially distributed ventilation pipes 100 can be added at will without limitation; the pipe opening of the ventilation pipe 100 is located outside the lamp housing 001;

[0043] When in use: When the lamp housing 001 is used for a long time, a lot of heat will be generated inside it. Due to the interlaced arrangement of multiple ventilation pipes 100, most of the heat at different positions in the lamp housing 001 is discharged to the external environment through the ventilation pipes 100 made of heat exchange material, thereby forming an efficient and uniform heat dissipation effect inside the lamp housing 001;

[0044] At the same time, similar to this type of lamp housing 001 installed in an outdoor environment, such as Figure 4 As shown, when natural wind is formed in the surrounding environment, it will blow toward the lamp housing 001 from different directions, and the multiple ventilation pipes 100 distributed in the circumferential direction of the lamp housing 001 will form a pipe opening of at least one ventilation pipe 100 to receive the natural wind, and the multiple ventilation pipes 100 are interconnected, so that the natural wind forms a flow when passing through the ventilation pipes 100, which can accelerate the dissipation of heat inside the lamp housing 001 through the flow of gas, and further improve the heat dissipation effect of the lamp housing 001;

[0045] Moreover, with the provision of the ventilation duct 100, the lamp housing 001 as a whole can be completely sealed, making it waterproof, dustproof, and anti-corrosive, and the ventilation duct 100 dissipates heat inside the lamp housing 001, making it very suitable for outdoor lighting and industrial environments.

[0046] Reference Figure 4 As shown, further, the opening of the ventilation pipe 100 located outside the lamp housing 001 is beveled;

[0047] When in use: by setting the bevel angle, the air inlet area of ​​the opening of the ventilation duct 100 can be increased, the amount of natural wind entering can be increased, and the heat dissipation effect of the ventilation duct 100 on the lamp housing 001 can be improved.

[0048] Reference Figure 4 As shown, further, the bevel angles of the two pipe openings of the same ventilation pipe 100 are in opposite directions;

[0049] When in use: when the crosswind in the air blows toward the lamp housing 001, it is ensured that the air passes through the pipe opening of at least one ventilation pipe 100 located outside the lamp housing 001, and the pipe opening of the ventilation pipe 100 opposite to the air inlet is located on the other side of the lamp housing 001, that is, the air outlet;

[0050] This setting can ensure that the airflow will only pass through one pipe opening on this ventilation duct 100. At this time, the two pipe openings of the ventilation duct 100 form an in-and-out effect, ensuring that the airflow entering the ventilation duct 100 will not interfere, thereby improving the flow effect, thereby enhancing the ability of the airflow to form heat exchange with the inner wall of the ventilation duct 100 located in the lamp housing 001, thereby enhancing the heat dissipation of different areas in the lamp housing 001 and improving the heat dissipation effect.

[0051] Reference Figure 1 , Figure 2 and Figure 3 As shown, a liquid guide hopper 101 with a wide upper opening and a narrow lower opening is installed above the lamp housing 001, and a filter screen (not shown in the figure) is laid at the wide opening of the liquid guide hopper 101 to prevent external debris from falling into the liquid guide hopper 101; a connecting pipe 102 is also installed at the narrow lower opening of the liquid guide hopper 101; the connecting pipe 102 passes through the lamp housing 001 and is connected with the junction of the plurality of ventilation pipes 100;

[0052] When in use: In rainy weather, the liquid guide hopper 101 can receive rainwater in the air, so that the rainwater is slowly introduced into a plurality of interconnected ventilation pipes 100 from the connecting pipe 102, and flows out from the pipe opening of the ventilation pipe 100 located outside the lamp housing 001, in this process, the heat exchange and cooling effect of the ventilation pipe 100 is improved;

[0053] At the same time, there is air flow inside the ventilation duct 100 during use, which causes dust in the air to adhere to the inner wall of the ventilation duct 100. After excessive accumulation, a heat insulation layer will be formed to a certain extent, which will hinder the internal temperature of the lamp housing 001 from transferring heat to the outside, resulting in a decrease in the overall heat dissipation effect of the lamp housing 001. Rainwater enters the ventilation duct 100 from the liquid guide bucket 101 and the connecting pipe 102 and cleans the inner wall of the ventilation duct 100 during the discharge process, so that the dust attached to the inner wall can be removed, ensuring that the inner wall of the ventilation duct 100 is relatively clean, thereby enhancing the heat exchange and cooling effect of the ventilation duct 100 on the heat in the lamp housing 001.

[0054] Reference Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, each ventilation pipe 100 is provided with a plurality of interconnected cross pipes 103; the cross pipe 103 is composed of vertical pipes and horizontal pipes interconnected with each other, which can be Figure 8 As shown; wherein, the two ends of the vertical tube are opened, one of which is connected to the inside of the lamp housing 001, and the other is connected to the inside of the ventilation pipe 100; the two ends of the horizontal tube are blocked; a slider 104 is installed in the horizontal tube to fit its inner wall; a heat dissipation mesh port 105 is opened through the slider 104, which is specifically composed of a heat dissipation port and a filter, wherein the filter structure is not shown, which is specifically installed at the hole at the bottom of the heat dissipation mesh port 105 and forms a trajectory consistent with the arc-shaped side of the slider 104, and its main function is to isolate air and dust from entering the interior of the lamp housing 001, and the central axis of the heat dissipation mesh port 105 is parallel to the central axis of the vertical tube; a heat expansion member 106 and a connecting spring 107 are also installed in the horizontal tube, which are located on both sides of the slider 104; the two ends of the connecting spring 107 are respectively fixed to the slider 104 and the inner wall of the horizontal tube; wherein, under the action of the connecting spring 107, the end of the slider 104 away from the connecting spring 107 is always in contact with the heat expansion member 106;

[0055] It should be added that the heat expansion member 106 can be a heat expansion strip or a heat expansion airbag-like component. As for the thermal expansion coefficient or the expansion temperature range, the corresponding material can be selected by the user, and no further details will be given.

[0056] When using: Figure 6 and Figure 7 As shown, the cross tube 103 is preferably installed at the top of the ventilation tube 100, so that when the liquid in the liquid guide bucket 101 is introduced into the ventilation tube 100 in rainy weather, it will not penetrate into the cross tube 103 or transition into the lamp housing 001 through it;

[0057] Meanwhile, the present invention provides a plurality of ventilation pipes 100 to ensure the heat dissipation in the lamp housing 001. However, when the lamp is used for a long time or in hot summer weather, the internal heat will not be dissipated in time, and the heat dissipation effect is poor, which affects the service life of the internal components.

[0058] To this end, the present invention also cooperates with the cross tube 103 and other structures, when the heat in the lamp housing 001 is high, such as Figure 8 As shown, the temperature rise inside the lamp housing 001 will cause the heat expansion member 106 to expand due to the heat, thereby pushing the slider 104 to move right and squeezing the connecting spring 107 to compress. At this time, the heat dissipation mesh port 105 will form a conductive state with the vertical pipe during the movement of the slider 104 to the right (when the slider 104 moves to the right to the maximum stroke, the central axis of the heat dissipation mesh port 105 on it overlaps with the central axis of the vertical pipe). At this time, the heat inside the lamp housing 001 can enter the ventilation pipe 100 from the vertical pipe of the cross pipe 103 and the heat dissipation mesh port 105, thereby cooperating with the ventilation pipe 100 to enhance the heat dissipation effect;

[0059] Moreover, when the cross wind blows into the ventilation pipe 100, since the vertical pipe of the cross pipe 103 is arranged vertically and connected to the ventilation pipe 100, and the pipe opening is located in the ventilation pipe 100, the cross wind airflow entering the ventilation pipe 100 in the process will accelerate the airflow at the pipe opening of the vertical pipe in the ventilation pipe 100, thereby accelerating the extraction of heat in the lamp housing 001 and improving the heat dissipation effect inside the lamp housing 001;

[0060] On the contrary, when the temperature inside the lamp housing 001 tends to a relatively normal value, Figure 8As shown, the heat expansion member 106 shrinks and resets, and the compressed connecting spring 107 can also push the slider 104 to move to the left during the reset process. At this time, the heat dissipation mesh port 105 on the slider 104 will be in a state of being in contact with the inner wall of the horizontal tube after the reset movement (in the heat dissipation state, the heat dissipation mesh port 105 and the vertical tube form a conductive state), that is, the heat dissipation mesh port 105 is not connected to the vertical tube portion of the cross tube 103 at this time (which means that the ventilation pipe 100 is not connected to the inside of the lamp housing 001). The above situation is that the lamp is not in the lighting state, or in rainy weather, and its internal heat is at a relatively normal value. At this time, the ventilation pipe 100 is not connected to the inside of the lamp housing 001, so that external moisture will not enter the inside of the lamp housing 001 from the ventilation pipe 100, preventing its internal components from being damaged by moisture, so that the lamp housing 001 has the effect of moisture and dustproof.

[0061] At the same time, as the slider 104 moves to the left, the filter screen (not shown in the figure) at the bottom hole of the heat dissipation mesh port 105 will scrape against the end of the junction of the horizontal pipe and the vertical pipe, thereby scraping off the dust and impurities blocked on the filter screen and cleaning it;

[0062] In summary, when the internal temperature of the lamp housing 001 is at a relatively normal value, the ventilation duct 100 is used to dissipate the heat inside the lamp housing 001, so that it has the ability to be moisture-proof and dust-proof; when the internal temperature of the lamp housing 001 exceeds the normal value, the cross tube 103 and the ventilation duct 100 are connected under the transition of the heat dissipation mesh port 105, and cooperate with the ventilation duct 100 to enhance the dissipation of the internal temperature of the lamp housing 001 and improve the heat dissipation effect.

[0063] Reference Figure 2 , Fig. 9 and Fig.10 As shown, the lamp housing 001 is also radially mounted with a support beam 200 located below it; the support beam 200 is provided with a rubber strip 201 that is tightly fitted with the cover plate 002; the cover plate 002 and the lamp housing 001 are connected in a rotating seal; wherein, when the surface of the cover plate 002 needs to be cleaned, it can rotate around its own axis and continuously contact with the rubber strip 201 to wipe and clean; it should be noted that the support beam 200 and the rubber strip 201 have a small shielding area for the cover plate 002, which will not affect the emission of light, and the support beam 200 and the rubber strip 201 can both be made of transparent materials, and the two can be made of transparent acrylic and transparent rubber respectively;

[0064] When in use: when dust, flying insects and other debris adhere to the transparent cover plate 002 and need to be cleaned, the cover plate 002 can be rotated around its own axis. During the rotation, the cover plate 002 will continuously contact and wipe the rubber strip 201 that is tightly attached to its surface, thus forming a self-cleaning process;

[0065] Compared with the prior art, the difference is that during cleaning, the cover plate 002 continuously rotates around its own axis, and the overall position of the rubber strip 201 as a cleaning member is stationary. On the one hand, the rubber strip 201 is forced to contact the cover plate 002 during the rotation process, so as to clean the attachments on the surface of the cover plate 002; on the other hand, during the cleaning process, since the rubber strip 201 will not form a position change, the light irradiated on the ground will not form light and shadow and shake, so as to have a better lighting effect and realize the cleaning of the cover plate 002; furthermore, the cover plate 002 forms a dynamic change process during the rotation process, which can interfere with the flight trajectory of the flying insects or make it difficult for them to attach to the cover plate 002 for a long time, reduce the problem of the flying insects covering the cover plate 002 and blocking the light, and ensure the light transmission effect of the cover plate 002.

[0066] Reference Fig. 9 and Fig.10 As shown, further, the length of the rubber strip 201 located below the cover plate 002 is not less than the radius of the cover plate 002;

[0067] During use: the length of the contact portion between the rubber strip 201 and the cover plate 002 is not less than the radius of the circular cover plate 002. This arrangement allows the end of the rubber strip 201 to wipe and clean all surfaces of the cover plate 002 once the cover plate 002 rotates one circle. Although the contact / shielding area of ​​the rubber strip 201 on the cover plate 002 is small, all surfaces can still be cleaned during the rotation of the cover plate 002.

[0068] Reference Fig.12 and Fig.13 As shown, specifically, in order to realize that the cover plate 002 can rotate around its own axis; for this purpose, the cover plate 002 is also covered with a gear ring 202 arranged concentrically therewith; a motor is also installed on the side of the lamp housing 001, which is shown in the figure but not numbered; a gear 1 203 is installed on the output shaft of the motor; the gear 1 203 is meshed with the gear ring 202;

[0069] When in use: When the cover plate 002 needs to be cleaned, the motor can be actively controlled or equipped with a timer switch to control the motor action;

[0070] That is, when the motor is in operation, its output shaft can drive gear 203 to rotate, gear 203 can drive the gear ring 202 meshing therewith to rotate, and the gear ring 202 can drive the cover plate 002 fixed thereto to rotate in the same direction on the lamp housing 001 (the cover plate 002 and the lamp housing 001 are connected in a rotating seal), that is, through the arrangement of the above structure, the cover plate 002 can be realized to rotate around its own axis.

[0071] Reference Fig.11 , Fig.12 and Fig.13As shown, the rubber strip 201 is connected end to end and tightly sleeved on the support beam 200; both ends of the support beam 200 are equipped with rotating rods for supporting the rubber strip 201; the top of the rotating rod located outside the lamp housing 001 is also equipped with a gear 204, and the gear 204 is meshed with the gear 1 203;

[0072] When in use: on the basis of the motor driving the gear 1 203 to move, the gear 1 203 can also drive the gear 2 204 meshing therewith to rotate, and the gear 2 204 can drive the rotating rod to rotate synchronously. Since the rubber strip 201 is connected end to end and tightly sleeved on the two rotating rods and the support beam 200, the rotation of the rotating rod can make the rubber strip 201 form a conveying effect on the support beam 200;

[0073] However, when the rubber strip 201 wipes and cleans the surface of the cover plate 002, some impurities such as dust and flying insects that fall off the cover plate 002 will adhere to the end of the rubber strip 201, which may cause secondary pollution and have a counterproductive effect during the next cleaning. In addition, such attachments may solidify, thereby affecting the wiping and cleaning effect of the rubber strip 201 on the cover plate 002.

[0074] To this end, the present invention provides the rubber strip 201 with the ability to transport and move on the support beam 200, thereby preventing the cover plate 002 from always contacting the same end of the rubber strip 201 when rotating. By switching the ends of the rubber strip 201 at different and relatively clean positions to contact the surface of the cover plate 002, the effect of the rubber strip 201 wiping and cleaning the cover plate 002 is improved. At the same time, the rubber strip 201 with the transporting ability can throw off the attachments on its end during the movement, thereby ensuring the cleaning effect for the next use.

[0075] Reference Fig.12 and Fig.13 As shown, a scraper 205 is also installed on the side of the lamp housing 001; the end of the scraper 205 is always in contact with the side of the rubber strip 201;

[0076] During use: the impurities cleaned off the surface of the cover plate 002 by the rubber strip 201 will adhere to the end of the rubber strip 201, and the rubber strip 201 can form a circular conveyor on the support beam 200. During this process, the impurities attached to the end of the rubber strip 201 can be scraped and cleaned in conjunction with the setting of the scraper 205, ensuring that the end of the rubber strip 201 is relatively clean after contacting the scraper 205, so that the cover plate 002 can always contact the clean end of the rubber strip 201 during the continuous rotation process, thereby improving the contact and wiping effect of the rubber strip 201 on the surface of the cover plate 002.

[0077] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
