Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, and more specifically to a lightweight stage lamp with a waterproof and breathable window. Background Art

[0002] As a performance application product, stage lighting needs to adapt to various weather conditions. However, the existing outdoor stage lights with good waterproof performance are expensive, and the indoor stage lights that are not waterproof cannot meet the requirements of outdoor use. Usually, stage lights are not installed and used outdoors in extreme weather such as heavy rain, so stage lights that are occasionally used outdoors do not need a high waterproof level. Therefore, it is urgent to design a lamp that has a certain waterproof level and costs less than a high waterproof stage light. Utility Model Content

[0003] In order to overcome at least one defect of the above-mentioned prior art, the utility model provides a lightweight stage lamp with a waterproof and breathable window. In performance occasions where a high waterproof level is not required, the waterproof level required by the venue can be guaranteed, and the use of expensive metal materials such as aluminum alloy is avoided, thereby reducing the overall weight of the stage lamp and meeting the requirements for waterproofness, weight, price and other aspects of stage lamps.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a lightweight stage lamp with a waterproof and breathable window, including a lamp head, a light source is provided in the lamp head, and also includes a lamp shell wrapping the outer periphery of the lamp head, the lamp shell includes a left supporting side panel and a right supporting side panel arranged opposite to each other, and also includes a front shell and a rear shell on both sides respectively interlocked with the left supporting side panel and the right supporting side panel, an inner cavity is formed inside the lamp shell, and a ventilation through hole is provided on the front shell and / or the rear shell, characterized in that a first waterproof circuit is provided on the periphery of the ventilation through hole, the first waterproof circuit is located outside the inner cavity, a waterproof baffle is further provided outside the inner cavity corresponding to the ventilation through hole, a second waterproof circuit is provided on the side of the waterproof baffle close to the ventilation through hole, and the first waterproof circuit and the second waterproof circuit are staggered to form a maze waterproof ventilation structure.

[0005] By opening ventilation holes in the left shell and / or the right shell, a way can be provided for the gas flow exchange between the inner cavity of the lamp shell and the outside world, so that the cold air from the outside world can enter the inner cavity to dissipate the heat of the components of the lamp, thereby meeting the heat dissipation requirements of the lamp, and a waterproof cover is arranged corresponding to the ventilation holes, a first waterproof circuit is arranged around the ventilation holes, and a second waterproof circuit is arranged on the waterproof cover. The first waterproof circuit and the second waterproof circuit are staggered to form a maze waterproof ventilation structure, which can prevent rainwater caused by rain or other extreme conditions from directly pouring into the interior of the lamp. The multiple superposition and staggering make it difficult for external water to penetrate into the interior of the lamp, meeting certain waterproof requirements.

[0006] Furthermore, both the left support side plate and the right support side plate are made of metal, and both the front shell and the rear shell are made of plastic. The left support side plate and the right support side plate made of metal have higher strength and can better support the lamp head. Making the front shell and the rear shell with plastic material can well reduce the overall weight of the stage light, and the plastic material has a lower cost than the metal material, enabling the stage light to be lighter in weight and lower in price.

[0007] Furthermore, the outer side surface of the lamp shell has a depression, the first waterproof circuit is located in the depression, at least two fixing columns are arranged in the depression, the waterproof cover is connected to the fixing columns by screws, and the outer side surface of the waterproof cover is flush with the surface of the lamp shell, with a smooth transition. After the waterproof cover is fixed to the fixing columns, its outer side surface can have a smooth transition with the lamp shell, making the appearance more beautiful.

[0008] Furthermore, the first waterproof circuit includes a first waterproof rib, and at least one of the first waterproof ribs is provided with a water-blocking bend on the side away from the inner cavity;

[0009] The second waterproof circuit includes a second waterproof rib, and at least one of the second waterproof ribs is provided with a water-blocking bend on the side close to the inner cavity;

[0010] The first waterproof rib and the second waterproof rib are arranged in an interleaved manner. The more the first waterproof rib and / or the second waterproof rib, the more waterproof layers can be stacked, thereby increasing the waterproof level. The water-blocking bend can prevent the water accumulated on the first waterproof rib and / or the second waterproof rib from directly flowing into the inner cavity or the next layer of the first waterproof rib and / or the second waterproof rib from the edge of the movable side.

[0011] Furthermore, the first waterproof rib and the second waterproof rib provided with the water-blocking bend are arranged adjacent to each other in an interleaved manner. The adjacent superposition of two first waterproof ribs and second waterproof ribs with water-blocking bends can further enhance the waterproof property.

[0012] Furthermore, the first waterproof rib provided with the water-blocking bend is located on the outermost side of the first waterproof circuit;

[0013] The second waterproof rib provided with the water-blocking bend is located on the outermost side of the second waterproof circuit. The closer to the outside, the greater the amount of water. Setting the first waterproof rib and / or the second waterproof rib provided with the water-blocking bend on the outermost side can block most of the water from entering the first waterproof circuit and / or the second waterproof circuit from the source, thereby greatly avoiding the possibility of water entering the inner cavity.

[0014] Furthermore, the first waterproof circuit is provided with a drainage notch. By providing the drainage notch, the water accumulated on the first waterproof circuit can flow away from the drainage notch, avoiding the accumulated water from entering the inner cavity.

[0015] Further, the outer side surface of the lamp housing has a depression, the first waterproof circuit is located in the depression, the lamp housing is provided with a drain hole, and the drain hole is arranged corresponding to the drain notch. The water flowing out of the drain notch can help accelerate the outflow from the depression surface of the first waterproof circuit through the drain hole, so that water will not accumulate on the depression surface.

[0016] Further, the innermost side of the first waterproof circuit further includes a continuous annular waterproof boss, and the top end of the annular waterproof boss is higher than the height of the first waterproof circuit. The height of the annular waterproof boss being higher than that of the first waterproof circuit can receive the water that has passed through the first waterproof circuit and prevent the water from directly flowing into the inner cavity. The continuous annular shape can prevent the water from flowing through the drain notch and directly flowing into the inner cavity.

[0017] Further, an annular sealing strip is fixed to the annular waterproof boss on the side away from the inner cavity. The outer edge of the annular sealing strip protrudes from the annular waterproof boss. A pressing frame for fixing the annular sealing strip to the annular waterproof boss is also included, and there is a gap between the pressing frame and the waterproof cover. By providing the annular sealing strip, it can further prevent the water accumulated on the annular waterproof boss from directly flowing into the inner cavity from the edge on the movable side. The pressing frame can make the annular sealing strip always abut and be fixed to the annular waterproof boss. The gap between the pressing frame and the waterproof cover allows the outside air to enter the inner cavity through the gap.

[0018] Further, the annular waterproof boss is provided with an inner groove, and the annular sealing strip has a sealing rib corresponding to the inner groove, and the sealing rib is in close fit with the inner groove. This further strengthens the connection tightness between the annular waterproof boss and the annular sealing strip. Description of the Drawings
