Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to a corrosion-resistant LED lamp. Background Technology

[0002] LED floodlights are lighting fixtures that provide higher illuminance to the illuminated surface than the surrounding environment. They are also known as spotlights. Typically, they can be aimed in any direction and have a structure that is unaffected by weather conditions. Almost all large-area outdoor lighting fixtures can be considered floodlights.

[0003] As prior art, Chinese patent CN215061497U proposes an LED floodlight with good corrosion resistance, including an LED floodlight body, a protective layer on the surface of the LED floodlight body, the protective layer including a high temperature resistant layer, a waterproof layer on the surface of the high temperature resistant layer, an aging resistant layer on the surface of the waterproof layer, a corrosion resistant layer on the surface of the aging resistant layer, and a wear resistant layer on the surface of the corrosion resistant layer.

[0004] While the above solution provides some corrosion protection, the protective layer is composed of multiple layers, including a high-temperature resistant layer, a waterproof layer, an aging-resistant layer, a corrosion-resistant layer, and a wear-resistant layer, bonded together. Long-term use in high-temperature or humid environments may lead to the risk of interface peeling. Furthermore, there is no warning or alert when the protective layer is damaged, making it difficult for users to replace it in a timely manner. Therefore, there is still room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a corrosion-resistant LED lamp to solve the problems mentioned in the background art.

[0006] To solve the above technical problems, this utility model adopts the following technical solution: a corrosion-resistant LED lamp, including a lamp housing, the lamp housing having an inner cavity, the inner cavity having LED beads, the surface of the lamp housing having a protective layer, the protective layer including a plurality of longitudinally arranged protective plates 1 and a plurality of transversely arranged protective plates 2, the rear end of the protective plate 2 abutting against the front side of the corresponding protective plate 1; and further including a metal edging strip detachably connected to the protective layer, the metal edging strip being made of a bendable flexible metal material, the metal edging strip connecting and fixing adjacent protective plates 2 and protective plates 1.

[0007] Using the above technical solution, the protective layer is divided into protective sheet one and protective sheet two, which are designed as detachable modules. When a local area is damaged, it can be replaced separately, reducing maintenance costs. A metal edging is set at the connection between protective sheet one and protective sheet two, which increases the overall structural strength of the protective layer while connecting protective sheet one and protective sheet two, thus reinforcing vulnerable parts.

[0008] As a further optimization of this utility model, the rear end of the second protective sheet is provided with a sealing strip, which abuts against the front side of the first protective sheet.

[0009] By adopting the above technical solution, a sealing strip is set to reduce the gap at the connection between the first protective sheet and the second protective sheet, thereby increasing the sealing performance of the protective layer. The sealing strip is made of silicone, which has strong weather resistance.

[0010] As a further optimization of this utility model, the rear side of the second protective sheet is provided with several slots, the periphery of the first protective sheet is provided with several slots, and the metal edging strip is provided with several locking blocks at intervals along the length direction, the locking blocks being able to engage with the slots.

[0011] As a further optimization of this utility model, the surface of the lamp housing is provided with several humidity sensors, and the inner cavity is provided with a controller and a buzzer. The humidity sensors and the buzzer are electrically connected to the controller.

[0012] Using the above technical solution, when the protective layer is damaged, the humidity sensor detects the humidity signal and transmits it to the controller. When the controller detects that the humidity is higher than the preset value, it controls the buzzer to sound, thereby reminding the user.

[0013] As a further optimization of this utility model, the protective layer includes a high-temperature resistant layer, a waterproof layer is disposed on the surface of the high-temperature resistant layer, and an aging-resistant layer is disposed on the surface of the waterproof layer. The material is a high-temperature resistant release film, the waterproof layer is a waterproof and breathable film, the surface of the aging-resistant layer is provided with a corrosion-resistant layer, and the surface of the corrosion-resistant layer is provided with a wear-resistant layer; the corrosion-resistant layer is a polytetrafluoroethylene composite material, and the aging-resistant layer is a TPU material.

[0014] Using the above technical solutions, the existing technology's corrosion-resistant layer, made of polytetrafluoroethylene (PTFE) film, has low mechanical strength and may be damaged by friction or impact after long-term use. The aging-resistant layer, made of PVC, has poor environmental friendliness and may release harmful substances at high temperatures. The corrosion-resistant layer is replaced with a PTFE composite material, balancing corrosion resistance and mechanical strength. The aging-resistant layer uses TPU material to prevent the release of harmful substances at high temperatures.

[0015] The beneficial effects of this utility model are as follows: the protective layer is divided into a protective sheet one and a protective sheet two, and is designed as a detachable module, which can be replaced separately when a local part is damaged, thus reducing maintenance costs; a metal edging is set at the connection between the protective sheet one and the protective sheet two, which increases the overall structural strength of the protective layer while connecting the protective sheet one and the protective sheet two, thus reinforcing the vulnerable parts. When the protective layer is damaged, the humidity sensor detects the humidity signal and transmits it to the controller. When the controller detects that the humidity is higher than the preset value, it controls the buzzer to sound, thereby reminding the user. Attached Figure Description

[0018] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0019] See appendix Figure 1-3 The present embodiment of this utility model further includes: a corrosion-resistant LED lamp 12, comprising a lamp housing 1, an inner cavity 11, an LED lamp 12 bead, and a protective layer on the surface of the lamp housing 1. The protective layer includes a plurality of longitudinally arranged protective plates 21 and a plurality of transversely arranged protective plates 22. The rear end of the protective plate 22 abuts against the front side of the corresponding protective plate 21. Furthermore, a sealing strip 5 is provided at the rear end of the protective plate 22, and the sealing strip 5 abuts against the front side of the protective plate 21. It also includes a metal edging strip 3 that is detachably connected to the protective layer. The metal edging strip 3 is made of flexible metal material that can be bent. The metal edging strip 3 connects and fixes the adjacent second protective sheet 22 and the first protective sheet 21. Specifically, the second protective sheet 22 has several slots 41 on its rear side and the first protective sheet 21 has several slots 41 on its periphery. The metal edging strip 3 has several locking blocks 42 spaced along its length. The locking blocks 42 can engage with the slots 41. The surface of the lamp housing 1 is provided with several humidity sensors 8, and the inner cavity 11 is provided with a controller 6 and a buzzer 7. The humidity sensors 8 and the buzzer 7 are electrically connected to the controller 6. Furthermore, the protective layer includes a high-temperature resistant layer 91, a waterproof layer 92 is disposed on the surface of the high-temperature resistant layer 91, and an aging-resistant layer 93 is disposed on the surface of the waterproof layer 92. The materials used are a high-temperature resistant release membrane, a waterproof layer 92 made of a waterproof and breathable membrane, a corrosion-resistant layer 94 on the surface of the aging-resistant layer 93, and a wear-resistant layer 95 on the surface of the corrosion-resistant layer 94. The corrosion-resistant layer 94 is made of polytetrafluoroethylene (PTFE) composite material, and the aging-resistant layer 93 is made of TPU. In existing technologies, the corrosion-resistant layer 94 using PTFE membrane has low mechanical strength and may break due to friction or impact after long-term use. The aging-resistant layer 93 using PVC material has poor environmental friendliness and may release harmful substances at high temperatures. Therefore, the corrosion-resistant layer 94 is changed to PTFE composite material, balancing corrosion resistance and mechanical strength. The aging-resistant layer 93 uses TPU material to prevent the release of harmful substances at high temperatures.

[0020] The principle of this utility model is as follows: the protective layer is divided into a first protective sheet 21 and a second protective sheet 22, which are designed as detachable modules. When a part is damaged, it can be replaced separately, reducing maintenance costs. Metal edging is provided at the connection between protective sheet 1 21 and protective sheet 22 to increase the overall structural strength of the protective layer while connecting the two sheets, thus reinforcing vulnerable parts; sealing strip 5 is provided to reduce the gap at the connection between protective sheet 1 21 and protective sheet 22 and increase the sealing performance of the protective layer. The sealing strip 5 is made of silicone, which has strong weather resistance. When the protective layer is damaged, the humidity sensor detects the humidity signal and transmits it to the controller 6. When the controller 6 detects that the humidity is higher than the preset value, it controls the buzzer 7 to sound, thereby reminding the user.

[0021] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
