Description

Technical Field

[0001] This invention relates to the field of stage lighting technology, and in particular to a breathable and waterproof structure. Background Technology

[0002] Stage lights play a crucial role in creating atmosphere during stage performances. These performances can be indoors or outdoors. Outdoor performances require stage lights to withstand various weather conditions, especially rain, necessitating waterproofing. Currently, many existing waterproof stage lights have a waterproof rating of IP65. However, by designing the lamp housing with a sealed structure, the heat generated by the stage light accelerates the aging of internal components, resulting in high manufacturing and after-sales costs. In practical use, some waterproof stage lights used only occasionally for outdoor performances do not need to meet IP65; IP54 is sufficient. Therefore, there is an urgent need to improve stage lights. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a breathable and waterproof structure, which mainly solves the problems mentioned in the background art.

[0004] This invention proposes a ventilated and waterproof structure, comprising a first baffle and a second baffle. The second baffle is sealed to the wall of a lamp housing. The second baffle includes a convex shell disposed on the side of the second baffle facing away from the wall of the lamp housing. The convex shell and the first baffle are sealed together. The convex shell has a channel inside, which connects the interior of the lamp housing and a through-hole. The through-hole is disposed on the wall of the convex shell and is located between the first baffle and the second baffle. The first baffle includes a first ring and a second ring, and the first ring and the second ring... The surrounding rings are respectively disposed on the side of the first baffle facing the second baffle. The second baffle also includes a third surrounding ring and a fourth surrounding ring, and the third surrounding ring and the fourth surrounding ring are respectively disposed on the side of the second baffle facing the first baffle. The convex shell, the fourth surrounding ring, the second surrounding ring, the third surrounding ring and the first surrounding ring are spaced apart to form a connecting air channel. The connecting air channel connects the through-hole and the external air of the lamp housing. The first baffle between the first surrounding ring and the second surrounding ring is provided with a first drain outlet, and the second baffle between the third surrounding ring and the fourth surrounding ring is provided with a second drain outlet.

[0005] A further improvement is that, along the horizontal direction, the orthographic projections of the fourth ring, the second ring, the third ring, and the first ring partially overlap.

[0006] A further improvement is that, in the vertical direction, the orthographic projection of the first drain outlet does not coincide with the orthographic projection of the third enclosure, and the first drain outlet is close to the first enclosure.

[0007] A further improvement is that a drainage protrusion is provided on the side of the first baffle facing away from the second baffle, and there is a gap between the bottom of the drainage protrusion and the first drain outlet. A drain outlet is provided on the wall of the drainage protrusion, and the drain outlet extends to the wall of the first baffle. The drain outlet and the first drain outlet are connected.

[0008] A further improvement is that the second drain outlet is close to the third enclosure; and in the vertical direction, the orthographic projection of the second drain outlet partially coincides with the orthographic projection of the second enclosure.

[0009] A further improvement is that the first ring is more aligned with the second shield than the second ring, and the fourth ring is more aligned with the first shield than the third ring.

[0010] A further improvement is that one end of the convex shell has an opening that communicates with the interior of the lamp housing, while the other end of the convex shell is a closed structure.

[0011] A further improvement is that the outer side of the wall of the convex shell is provided with a groove, and the groove is a circumferentially arranged concave structure. The groove is provided with a sealing ring, and the convex shell and the first baffle are connected in a sealed manner through the sealing ring.

[0012] A further improvement is that there are multiple through-holes, which are spaced apart circumferentially along the wall of the convex shell.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] This invention connects the internal and external air of the lamp housing through channels, through-holes, and air ducts, reducing the pressure difference between the inside and outside of the lamp housing. At the same time, the first drain outlet is the first waterproofing point, the second drain outlet is the second waterproofing point, and the fourth ring is the third waterproofing point, thus achieving waterproofing function and reaching IP54.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" 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; they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The technical solution of this invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] Reference Figure 1 and Figure 2 In one embodiment, a stage light includes a lamp housing 3, with an LED lamp 5 inside the lamp housing 3. The LED lamp 5 generates light and illuminates the outside of the lamp housing 3. The lamp housing 3 has at least one ventilated and waterproof structure, which is located on the side of the lamp housing 3 with a heat dissipation fan. The common exterior of the ventilated and waterproof structure and the heat dissipation fan is covered by a grille cover 4, which is fixedly connected to the lamp housing 3. The grille cover 4 has an opening and serves a protective function, reducing the risk of damage to the ventilated and waterproof structure and the heat dissipation fan from external objects.

[0028] Reference Figure 1-5In one embodiment, a ventilated and waterproof structure is provided, which includes a first cover 1 and a second cover 2. The second cover 2 is sealed to the wall of the lamp housing 3. For example, the seal can be achieved by a sealing ring 205, and the second cover 2 and the lamp housing 3 can be connected by bolts, or the second cover 2 and the lamp housing 3 can be sealed by glue.

[0029] Continue to refer to Figure 1-5 The second baffle 2 includes a convex shell 20, which is disposed on the side of the second baffle 2 facing away from the lamp housing 3. The convex shell 20 and the first baffle 1 are sealed together. The convex shell 20 has a channel 201 inside, which connects the interior of the lamp housing 3 and the through-hole 202. The through-hole 202 is disposed on the wall of the convex shell 20 and is located between the first baffle 1 and the second baffle 2. The first baffle 1 includes a first ring 11 and a second ring 12, which are respectively disposed on the side of the first baffle 1 facing the second baffle 2. The second baffle 2 also includes a third ring 21 and a fourth ring 22, which are respectively disposed on the side of the second baffle 2 facing the first baffle 1. The convex shell 20, the fourth ring 22, the second ring 12, the third ring 21, and the first ring 11 are spaced apart to form a connecting air passage. The LED lamp 5 generates heat while producing light, and the temperature can reach as high as At 80-90℃, since the interior of the lamp housing 3, the channel 201, the through-hole 202, the air duct, and the external air of the lamp housing 3 are interconnected, heat exchange can occur with the external air, lowering the internal temperature of the lamp housing 3 and reducing the pressure difference between the inside and outside of the lamp housing 3, thus reducing the probability of rainwater being pumped into the lamp housing 3. At the same time, the first baffle 1 between the first ring 11 and the second ring 12 is provided with a first drain outlet 13, and the second baffle 2 between the third ring 21 and the fourth ring 22 is provided with a second drain outlet 23. When it rains outside, the first drain outlet 13 acts as the first waterproofing point, which can drain a large amount of rainwater, reducing the amount of rainwater entering the second drain outlet 23. The second drain outlet 23 acts as the second waterproofing point, which can drain splashed rainwater through the second drain outlet 23. At this time, in conjunction with the third waterproofing point, namely the fourth ring 22, it further prevents rainwater from entering the interior of the lamp housing 3. The test results show that it reaches IP54. In this embodiment, the internal and external air of the lamp housing 3 are connected through the channel 201, the through-hole 202, and the air connection channel, thereby reducing the pressure difference between the inside and outside of the lamp housing 3. At the same time, the first drain outlet 13 is the first waterproofing point, the second drain outlet 23 is the second waterproofing point, and the fourth ring 22 is the third waterproofing point, thus achieving waterproofing function and reaching IP54.

[0030] Preferably, the first ring 11, the second ring 12, the third ring 21 and the fourth ring 22 are respectively a regular structure or an irregular structure that completely encloses the entire circle. The regular structure includes a ring structure or a square structure.

[0031] Preferably, the number of the first drain outlet 13 and the second drain outlet 23 is not less than one, and can be one, two, three or four, etc.

[0032] Preferably, the number of convex shells 20 is not less than one, and can be one, two or three, etc.

[0033] In one embodiment, along the horizontal direction, the orthographic projections of the fourth enclosure 22, the second enclosure 12, the third enclosure 21, and the first enclosure 11 partially overlap, thus serving to isolate rainwater.

[0034] In one embodiment, the orthographic projection of the first drain outlet 13 does not coincide with the orthographic projection of the third enclosure 21 in the vertical direction, and the first drain outlet 13 is close to the first enclosure 11, thereby accelerating the discharge of rainwater from the first drain outlet 13.

[0035] In one embodiment, a drainage protrusion 14 is provided on the side of the first baffle 1 facing away from the second baffle 2. There is a gap between the bottom of the drainage protrusion 14 and the first drain outlet 13. A drain outlet 15 is provided on the wall of the drainage protrusion 14 to play the role of directional drainage. The drain outlet 15 extends to the wall of the first baffle 1 and is connected to the first drain outlet 13 to prevent rainwater from accumulating in the first baffle 1.

[0036] In one embodiment, the second drain outlet 23 is close to the third enclosure 21, so that the third enclosure 21 can play the role of blocking rainwater; in the vertical direction, the orthographic projection of the second drain outlet 23 partially coincides with the orthographic projection of the second enclosure 12, widening the position of the second drain outlet 23, so as to further discharge splashed rainwater through the second drain outlet 23.

[0037] In one embodiment, the first ring 11 is more toward the second shield 2 than the second ring 12, and the fourth ring 22 is more toward the first shield 1 than the third ring 21, to further prevent rainwater from entering the lamp housing 3.

[0038] In one embodiment, one end of the convex shell 20 is provided with an opening 203, which communicates with the interior of the lamp housing 3. The other end of the convex shell 20 is a closed structure, which reduces the connection points between the lamp housing 3 and the external air, and provides directional connection and directional waterproofing.

[0039] In one embodiment, in order to reduce the connection between the interior and exterior air of the lamp housing 3, and to achieve directional connection and directional waterproofing, the outer side of the wall of the convex shell 20 is provided with a groove 204, and the groove 204 is a circumferentially arranged concave structure. The groove 204 is provided with a sealing ring 205, and the convex shell 20 and the first baffle 1 are sealed together by the sealing ring 205.

[0040] In one embodiment, there are multiple through-holes 202, which are spaced apart circumferentially along the wall of the convex shell 20, thereby increasing the number of through-holes 202 and accelerating the connection between the interior and exterior air of the lamp housing 3.

[0041] The positional relationships described in the figures are for illustrative purposes only and should not be construed as limiting the invention. Clearly, the above embodiments of the invention are merely examples to clearly illustrate the invention and are not intended to limit the implementation of the invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the invention should be included within the scope of protection of the claims of this invention.
