[0002] A luminaire is an appliance that transmits, distributes, and alters the light distribution of a light source. It is a combination of all components, except the light source itself, required for fixing and protecting the light source, as well as the wiring accessories necessary for connecting to the power supply.
[0003] If moisture enters the interior of a lamp, it may cause problems such as short circuits and component corrosion, which in turn can affect the normal operation of the lamp or even cause damage. Currently, some lamps used for outdoor lighting are prone to damage to circuit boards and LEDs due to water vapor when exposed to rain, snow, or other weather conditions. Therefore, in order to protect key elements such as circuit boards and LEDs from being affected, it is often necessary to install a waterproof shell on the outside of the lamp.
[0004] Since the lifespan of LED chips is often limited, lighting fixtures are often designed with detachable parts to replace the chips when they are damaged. However, since there are often gaps at the detachment points, moisture can more easily enter the lighting fixture through these gaps, affecting its use. Therefore, a waterproof housing structure for lighting fixtures is proposed to solve the above problems. Summary of the Invention

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Referring to Figures 1-3, one embodiment of this utility model is provided: a waterproof housing structure for a lamp, including a housing 1. The housing 1 is conical in shape, and the edge of the housing 1 is provided with an upwardly sloping portion. The shape of the housing 1 ensures that rainwater can slide down the outer wall of the housing 1 to the lowest point of its upper surface. A protective cover 2 is provided in the lower middle part of the housing 1. The protective cover 2 is colorless and transparent or translucent white. The protective cover 2 and the housing 1 are detachably connected by a connecting mechanism 3. When the protective cover 2 is removed, the staff can easily replace the lamp beads. A drain pipe 4 is fixedly connected to the inner wall of the protective cover 2, and rainwater can slide down the drain pipe 4.
[0033] Furthermore, a connecting rod 5 is fixedly connected to the bottom end of the drain pipe 4. Multiple connecting rods 5 are provided at the bottom of each drain pipe 4, and the multiple connecting rods 5 are arranged in a circular array around the axis of the drain pipe 4. The top of the connecting rod 5 is located at the lowest point of the upper surface of the housing 1, and the interior of the connecting rod 5 is connected to the upper surface of the housing 1. An ornamental ball 6 is fixedly connected to the bottom end of the connecting rod 5. The ornamental ball 6 enhances the aesthetics of the device. Multiple drain pipes 4 and multiple ornamental balls 6 are provided, and each drain pipe 4 and ornamental ball 6 corresponds to another. Both drain pipes 4 and ornamental balls 6 are arranged in a circular array around the axis of the housing 1, and the drain pipes 4 and ornamental balls 6 are colorless and transparent. The colorless and transparent design ensures that they do not easily block the light beam.
[0034] Referring to Figures 3-5, the connecting mechanism 3 includes a mounting ring 31, which is annular and has its upper surface fitted to the lower surface of the housing 1. The bottom end of the mounting ring 31 is fixedly connected to the top end of the protective cover 2. A plug ring 32 is fixedly connected to the middle of the top end of the mounting ring 31. The mounting ring 31, plug ring 32, and protective cover 2 are integrally formed. A slot 33 is fixedly connected to the lower surface of the housing 1 near the middle. The slot 33 is annular and has a T-shaped cross-section. An airbag 39 is fixedly connected to the outer wall of the plug ring 32. Multiple airbags 39 are provided and are respectively located on the inner and outer circumferential surfaces of the plug ring 32. The interior of the airbag 39 is connected to the interior of the air chamber 34. A waterproof groove 310 is provided on the inner wall of the housing 1. The cross-section of the waterproof groove 310 is semi-circular. When the plug ring 32 contacts the top inner wall of the slot 33, the waterproof groove 310 is located at the same height as the airbag 39.
[0035] Furthermore, the interior of the mounting ring 31 and the interior of the insertion ring 32 are both provided with a pressure chamber 34. The inner wall of the pressure chamber 34 is piston-connected to a sliding plate 35. The outer wall of the sliding plate 35 fits against the inner wall of the pressure chamber 34. The outer wall of the sliding plate 35 is fixedly connected to a locking block 36. The locking block 36 is cuboid in shape. The inner wall of the pressure chamber 34 is piston-connected to a sliding ring 37. The bottom of the sliding ring 37 is provided with a fixing component 38. The fixing component 38 includes a threaded rod 381. The number of threaded rods 381 is set to multiple, and the multiple threaded rods 381 are arranged in a circumferential array around the axis of the housing 1. The outer wall of the threaded rod 381 passes through and is threadedly connected to the inner wall of the mounting ring 31.
[0036] Working principle: When it rains, the rainwater slides along the upper surface of the housing 1 to the bottom of the upper surface, and then enters the drain pipe 4 and slides down along the inner wall of the drain pipe 4. Therefore, during this process, the rainwater above cannot directly enter the gap at the connection between the housing 1 and the protective cover 2.
[0037] Meanwhile, rainwater from the side enters the connection between the housing 1 and the protective cover 2 and needs to pass through the area where the drain pipe 4 is located. During this process, some rainwater will come into contact with the outer wall of the drain pipe 4 and be blocked.
[0038] In addition, even if the remaining rainwater can move to the connection position between the shell 1 and the protective cover 2 through the gap between the drain pipe 4, it needs to move horizontally and then upwards to enter the gap between the shell 1 and the protective cover 2. During the upward movement, it also needs to pass through the area where the airbag 39 and the waterproof groove 310 are located, so the water is difficult to enter the interior of the shell 1 and the protective cover 2.
[0039] When a light bulb needs to be replaced, the worker rotates the threaded rod 381, causing it to move downwards while rotating.
[0040] When the top of the threaded rod 381 no longer supports the sliding ring 37, the sliding ring 37 moves downward under the action of gravity. Therefore, the air pressure inside the air pressure chamber 34 is relatively low due to the increased space. As a result, the sliding plate 35 moves the locking block 36 towards the direction of entering the air pressure chamber 34 under the action of air pressure. At the same time, the airbag 39 contracts, so the staff can successfully remove the protective cover 2.
[0041] After the LED beads are replaced, the staff first inserts the insertion ring 32 into the slot 33, and then rotates the threaded rod 381. As the threaded rod 381 rotates, it moves upward, which reduces the space above the air chamber 34. Under the action of air pressure, the slide plate 35 moves the locking block 36 towards the top protrusion of the slot 33, and the airbag 39 inflates, thus ensuring that the protective cover 2 is relatively fixed to the shell 1, and that the gaps are occupied by the airbag 39, making it difficult for water to enter.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
