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

[0029] Continue to refer to Figure 1-5 The second blocking cover 2 includes a convex shell 20, which is arranged on the side of the wall of the second blocking cover 2 facing away from the lamp housing 3. The convex shell 20 and the first blocking cover 1 are sealed and connected. A channel 201 is provided inside the convex shell 20, and the channel 201 communicates with the interior of the lamp housing 3 and the through-opening 202. The through-opening 202 is provided on the wall of the convex shell 20 and the through-opening 202 is located between the first blocking cover 1 and the second blocking cover 2. The first blocking cover 1 includes a first enclosure 11 and a second enclosure 12, and the first enclosure 11 and the second enclosure 12 are respectively arranged on the side of the first blocking cover 1 facing the second blocking cover 2. The second blocking cover 2 also includes a third enclosure 21 and a fourth enclosure 22, and the third enclosure 21 and the fourth enclosure 22 are respectively arranged on the side of the second blocking cover 2 facing the first blocking cover 1. The convex shell 20, the fourth enclosure 22, the second enclosure 12, the third enclosure 21 and the first enclosure 11 are spaced apart to form a connecting airway. The LED lamp 5 is prone to heat while generating light, and the temperature can be as high as 80-90℃. At this time, since the interior of the lamp housing 3, the channel 201, the through-hole 202, the air connection channel and the external air of the lamp housing 3 are interconnected, heat exchange can be carried out with the external air to reduce the internal temperature of the lamp housing 3 and the pressure difference between the inside and outside of the lamp housing 3, so as to reduce the probability of rainwater being pumped into the interior of the lamp housing 3. At the same time, the first baffle 1 between the first enclosure 11 and the second enclosure 12 is provided with a first drain port 13, and the second baffle 2 between the third enclosure 21 and the fourth enclosure 22 is provided with a second drain port 23. When it rains outside, the first drain port 13 is the first waterproof part, which can discharge a large amount of rainwater and reduce the amount of rainwater entering the second drain port 23. The second drain port 23 is the second waterproof part, which can discharge the splashing rainwater through the second drain port 23. At this time, in conjunction with the third waterproof part, that is, the fourth enclosure 22, rainwater is further prevented from entering the interior of the lamp housing 3, and it has been tested to reach IP54. This embodiment connects the air inside the lamp housing 3 with the air outside the lamp housing 3 through the channel 201, the through-hole 202, and the connecting air 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 waterproof point, the second drain outlet 23 is the second waterproof point, and the fourth circle 22 is the third waterproof point, thereby realizing the waterproof function and reaching IP54.
