Description
Technical Field
[0001] The present application relates to the technical field of street lamps, and in particular to a ventilated cross-type external heat dissipation LED street lamp. Background Art
[0002] LED street lights are gradually coming into people's view with their advantages such as directional light emission, fast response speed, long service life and green environmental protection.
[0003] Some existing LED street lamps are mainly composed of a lamp pole, a bracket, a shell and a light-emitting component. When in use, the heat generated by the light-emitting component will be transferred outward through the shell, and then heat will be exchanged with the air to achieve the heat dissipation operation of the street lamp.
[0004] However, in the above process, since the street lamp transfers the heat generated by the light-emitting components only by means of natural heat dissipation, the street lamp is prone to poor heat dissipation during long-term use, resulting in a problem of reduced service life of the light-emitting components. Summary of the invention
[0005] The present application proposes a ventilated cross-type external heat dissipation LED street lamp, which has the advantage of increasing heat dissipation means, and is used to solve the problem that the street lamp has a single heat dissipation means, which leads to poor heat dissipation.
[0006] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: a ventilated cross-type external heat dissipation LED street lamp, comprising: a lamp pole, a bracket is fixedly installed on one side of the lamp pole, a lamp housing is fixedly installed on the end of the bracket facing away from the lamp pole, a light-emitting component is fixedly installed inside the lamp housing, a collecting cavity is equidistantly provided inside the lamp housing and located outside the light-emitting component, the opening of the collecting cavity is on the upper side of the lamp housing, and an air guide hole is provided on the outer side of the lamp housing and corresponding to the position of the collecting cavity, and the air guide hole connects the external environment with the collecting cavity.
[0007] Furthermore, a deflection plate is provided inside the collecting chamber, and the lower end of the deflection plate is inclined in the direction of the light-emitting component, and the lower end of the deflection plate is in sealed rotational connection with the bottom wall of the collecting chamber, and the upper end of the deflection plate is in sealed sliding contact with the inner wall of the collecting chamber, and the side of the deflection plate facing away from the air guide hole and the inner wall of the collecting chamber together form a water collecting chamber, and the water collecting chamber is connected with the opening of the collecting chamber, and a through hole is opened through the interior of the deflection plate, and the through hole is located at the upper position of the deflection plate, and a baffle is fixedly installed on the upper inner wall of the collecting chamber and close to the opening of the collecting chamber, and the minimum distance between the lower side of the baffle and the bottom wall of the collecting chamber is less than the length of the deflection plate, and the number of air guide holes corresponding to the collecting chamber is two, and the two air guide holes are arranged in an upper and lower distribution.
[0008] Furthermore, a rotating table is fixedly installed at the center position of the upper side surface of the lamp housing, and cross fan blades are rotatably installed above the rotating table. A protrusion is fixedly installed on the side of the deflection plate facing away from the light-emitting component, and the through hole is smoothly opened inside the deflection plate and inside the protrusion. The end of the protrusion facing away from the deflection plate is an arc-shaped end, and the arc-shaped end of the protrusion extends from the upper air guide hole to the external environment. A lever is fixedly installed on the lower side of the cross fan blades, and the lever is located outside the lamp housing. The minimum distance between the lever and the outer side surface of the lamp housing is less than the protruding length of the arc-shaped end of the protrusion.
[0009] Furthermore, the protrusions and the through holes are both arranged horizontally.
[0010] Furthermore, a cone ring is fixedly mounted on the upper side surface of the lamp housing and located outside the rotating platform, and the inner side of the upper side surface of the cone ring is arranged at a downwardly inclined angle.
[0011] Furthermore, the cone ring and the upper side of the lamp housing together form a groove, the opening of the collecting chamber is located above the bottom of the groove and is connected to the groove, and air holes are provided inside the cone ring and at positions corresponding to the openings of the collecting chamber, the inner ends of the air holes are connected to the groove, and the outer ends of the air holes are connected to the external environment.
[0012] Furthermore, the opening of the collecting chamber is parallel to the bottom surface of the groove.
[0013] Furthermore, the inner end of the vent hole is arranged at a downwardly inclined angle.
[0014] This application has the following beneficial effects:
[0015] The present application provides a ventilated cross-type external heat dissipation LED street lamp, which allows external air to enter the collecting chamber through the through hole and take away the heat generated by the light-emitting component through the arrangement of the collecting chamber, the deflection plate and the through hole. In addition, when it rains, part of the rainwater will enter the cavity surrounded by the collecting chamber and the deflection plate, so that the rainwater can be retained for a certain period of time. Afterwards, the rainwater is used to absorb the heat generated by the light-emitting component. Through the above-mentioned actions, the heat dissipation means are increased, making it less likely for the street lamp to have poor heat dissipation problems.
[0016] By setting the deflection plate, the protrusion, the cross blades and the lever, the rotating cross blades are used to drive the lever to rotate and contact the protrusion, so that the protrusion intermittently pushes the deflection plate to rotate. Afterwards, when the lever leaves the protrusion, the deflection plate and the protrusion are affected by their own gravity and reset, and this reciprocating process accelerates the air flow rate in contact with the position of the light-emitting component facing away from the windward side, thereby improving the heat dissipation effect of the street lamp. In addition, during the reciprocating rotation of the above-mentioned deflection plate, when there is rainwater in the cavity surrounded by the collecting cavity and the deflection plate, the reciprocatingly rotating deflection plate will intermittently squeeze the rainwater, causing the contact area between the rainwater and the inner wall of the collecting cavity to increase intermittently, thereby improving the heat dissipation effect of the street lamp.
[0017] By setting the deflection plate, the protrusion and the through hole, in the process of the deflection plate reciprocating and squeezing the rainwater, the protrusion will tilt as the deflection plate squeezes the rainwater, so that the rainwater whose liquid level rises due to the squeezing can rise to a height exceeding the through hole without flowing out. Through the above action, the use time of rainwater is extended and the heat dissipation effect of the street lamp is improved.
[0018] Through the setting of the collecting chamber and the ventilation holes, when the deflection plate squeezes the rainwater at a faster speed, part of the rainwater in the collecting chamber will flow to the upper side wall of the lamp housing. At this time, the air passing through the ventilation holes will come into contact with the rainwater, causing the rainwater to evaporate quickly and absorb the heat generated by the light-emitting component, thereby improving the heat dissipation effect of the street lamp.

DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0030] Example 1: Please refer to Figure 1 and Figure 4 A ventilated cross-type external heat dissipation LED street lamp comprises a lamp pole 1, a bracket 2 is fixedly installed on one side of the lamp pole 1, a lamp housing 3 is fixedly installed on the end of the bracket 2 facing away from the lamp pole 1, a light-emitting component 4 is fixedly installed inside the lamp housing 3, a collecting cavity 5 is equidistantly provided inside the lamp housing 3 and located outside the light-emitting component 4, the opening of the collecting cavity 5 is located on the upper side of the lamp housing 3, an air guide hole 6 is provided on the outer side of the lamp housing 3 and corresponding to the position of the collecting cavity 5, and the air guide hole 6 connects the external environment with the collecting cavity 5.
[0031] When in use, outside air can enter the collecting chamber 5 through the air guide hole 6 and take away the heat generated by the light-emitting component 4 (part of the heat generated by the light-emitting component 4 is transferred to the collecting chamber 5). In addition, when it rains (this device can be used in rainy cities), part of the rainwater will enter the collecting chamber 5, so that the rainwater can be retained for a certain period of time. After that, the rainwater is used to absorb the heat generated by the light-emitting component 4. Through the above-mentioned actions, the heat dissipation means are increased, making it less likely for the street lamp to have poor heat dissipation problems.
[0032] See also Figure 1-Figure 7A deflection plate 7 is arranged inside the collecting chamber 5, and the lower end of the deflection plate 7 is inclined toward the direction of the light-emitting component 4. The lower end of the deflection plate 7 forms a sealed rotating connection with the bottom wall of the collecting chamber 5, and the upper end of the deflection plate 7 forms a sealed sliding contact with the inner wall of the collecting chamber 5. The side of the deflection plate 7 facing away from the air guide hole 6 and the inner wall of the collecting chamber 5 together form a water collecting chamber, and the water collecting chamber is connected with the opening of the collecting chamber 5. A through hole 8 is opened through the interior of the deflection plate 7, and the through hole 8 is located in the upper position of the deflection plate 7. A baffle 9 is fixedly installed on the upper inner wall of the collecting chamber 5 and close to the opening of the collecting chamber 5. The minimum distance between the lower side of the baffle 9 and the bottom wall of the collecting chamber 5 is less than the length of the deflection plate 7, and the number of air guide holes 6 corresponding to the collecting chamber 5 is two, and the two air guide holes 6 are arranged in an upper and lower distribution.
[0033] Outside air can enter the water collecting chamber through the through hole 8 and take away the heat generated by the light-emitting component 4. In addition, when it rains, part of the rainwater will enter the water collecting chamber, so that the rainwater can be retained for a certain period of time. Later, when there is strong wind and there is still rainwater in the water collecting chamber, the deflection plate 7 corresponding to the windward side will be pushed by the air entering the collecting chamber 5 from the air guide hole 6, thereby causing the deflection plate 7 to rotate and continuously squeeze the rainwater in the water collecting chamber, so that the rainwater contacts the inner wall of the collecting chamber 5 (the inner wall of the collecting chamber 5 corresponding to the light-emitting component 4). The enlarged area improves the heat dissipation effect of the street lamp. At the same time, when the deflector plate 7 squeezes the rainwater at a faster speed (and there is still a lot of rainwater in the water collecting chamber), part of the rainwater in the collecting chamber 5 will flow to the upper wall of the lamp housing 3, so that the air at the upper side of the lamp housing 3 will contact this part of the rainwater, prompting this part of the rainwater to evaporate quickly and absorb the heat generated by the light-emitting component 4, thereby improving the heat dissipation effect of the street lamp. Finally, when the wind force decreases or disappears, the deflector plate 7 on the windward side is affected by its own gravity (and the gravity of the remaining rainwater) and then rotates and resets.
[0034] Example 2: Please refer to Figure 1-Figure 7 This embodiment is a further improvement of the first embodiment, and the improvement lies in that: a rotating table 10 is fixedly installed at the center position of the upper side of the lamp housing 3, a cross blade 11 is rotatably installed above the rotating table 10, a protrusion 12 is fixedly installed on the side of the deflection plate 7 facing away from the light-emitting component 4, and the through hole 8 is smoothly opened inside the deflection plate 7 and inside the protrusion 12, and the end of the protrusion 12 facing away from the deflection plate 7 is an arc-shaped end, and the arc-shaped end of the protrusion 12 extends from the upper air guide hole 6 to the external environment, and a lever 13 is fixedly installed on the lower side of the cross blade 11, and the lever 13 is located at the outer side of the lamp housing 3, and the minimum distance between the lever 13 and the outer side of the lamp housing 3 is less than the extension length of the arc-shaped end of the protrusion 12.
[0035] The cross blades 11 and the lever 13 are driven to rotate by wind force, so that the lever 13 contacts the protruding end of the leeward side protrusion 12, prompting the protrusion 12 to intermittently push the deflection plate 7 to rotate. Afterwards, when the lever 13 leaves the protrusion 12, the deflection plate 7 and the protrusion 12 on the leeward side are reset by their own gravity, and this reciprocating process accelerates the air flow rate contacted by the inner wall of the collecting chamber 5 located on the leeward side of the light-emitting component 4, thereby improving the heat dissipation effect of the street lamp. In addition, during the reciprocating rotation of the deflection plate 7 on the leeward side, when there is rainwater in the water collecting chamber, the reciprocatingly rotating deflection plate 7 will intermittently squeeze the rainwater, prompting the contact area between the rainwater and the inner wall of the collecting chamber 5 (the inner wall of the collecting chamber 5 corresponding to the light-emitting component 4) to intermittently increase, thereby improving the heat dissipation effect of the street lamp.
[0036] The bump 12 and the through hole 8 are both arranged horizontally.
[0037] In the process of the deflection plate 7 reciprocating and squeezing the rainwater, the protrusion 12 and the through hole 8 will be inclined as the deflection plate 7 squeezes the rainwater, so that the rainwater whose liquid level rises due to the squeezing can rise to a height exceeding the opening of the through hole 8 on the deflection plate 7 without flowing out. Through the above action, the use time of the rainwater is extended and the heat dissipation effect of the street lamp is improved.
[0038] See also Figure 1-Figure 7 A cone ring 14 is fixedly mounted on the upper side of the lamp housing 3 and located outside the rotating platform 10 , and the inner side of the upper side of the cone ring 14 is arranged at a downwardly inclined angle.
[0039] By disposing the cone ring 14, rainwater falling onto the upper side of the lamp housing 3 will be blocked by the cone ring 14 and then flow into the water collecting chamber, so that the water collecting chamber collects rainwater faster.
[0040] See also Figure 1-Figure 7 The cone ring 14 and the upper side of the lamp housing 3 together form a groove 15. The opening of the collecting chamber 5 is located above the bottom of the groove 15 and is connected to the groove 15. The opening of the collecting chamber 5 is parallel to the bottom of the groove 15. Ventilation holes 16 are provided inside the cone ring 14 and at positions corresponding to the openings of the collecting chamber 5. The inner ends of the ventilating holes 16 are connected to the groove 15, and the outer ends of the ventilating holes 16 are connected to the external environment. The inner ends of the ventilating holes 16 are arranged at a downwardly inclined angle.
[0041] When the deflection plate 7 squeezes the rainwater at a faster speed (and there is still a lot of rainwater in the water collecting chamber), part of the rainwater in the collecting chamber 5 will flow to the groove 15. At this time, the air passing through the ventilation hole 16 will come into contact with the rainwater in the groove 15, causing the part of the rainwater to evaporate quickly and absorb the heat generated by the light-emitting component 4, thereby improving the heat dissipation effect of the street lamp. By setting the groove 15, the air passing through the ventilation hole 16 can be prevented from blowing the rainwater away.
