Description

Technical Field

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

[0002] Against the backdrop of energy conservation and environmental protection, LED lighting fixtures are increasingly used in residential and commercial lighting due to their high light output efficiency and good light focusing performance. In commercial lighting, some applications require waterproofing, such as cold storage environments where high waterproofing levels are required. Typically, waterproof LED lights for ceiling lighting consist of a metal lamp holder, lampshade, circuit board, end cap, and driver. During manufacturing, the metal lamp holder connects to the lampshade to form the lamp body, and the connection points require waterproofing. The lamp body is also connected to the end cap and waterproofed. The driver is usually located in a layer behind the metal lamp holder. These fixtures using metal lamp holders are not only heavy but also require numerous sealed connections, resulting in high costs and less than ideal waterproofing performance. Therefore, it is necessary to develop a low-cost, high-waterproof LED waterproof light for ceiling lighting. Summary of the Invention

[0031] The following detailed description of specific embodiments of the present invention is based on the accompanying drawings. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0032] like Figures 1-8 As shown, the LED waterproof lamp of this embodiment includes a strip lamp holder 100, a strip circuit board 200 with an LED chip disposed on the strip lamp holder 100, and a lampshade 500 that is sealed to the strip lamp holder 100 to form a hollow lamp cavity 400. At least one of the mounting ports 401 at both ends of the hollow lamp cavity 400 is sealed by a terminal cover 300. Terminal covers 300 can be provided on both ends of the mounting port 401 of the hollow lamp cavity 400. In this embodiment, only one end uses a terminal cover 300, while the other end uses a general waterproof end cover 600. The waterproof end cover 600 includes an outer cover 601 and an inner cover 602.

[0033] There are many ways to connect the strip lamp holder 100 and the lampshade 500. Currently, the commonly used sealing connection method is to fill the connection position with sealant. This is not only cumbersome to assemble, but also results in a large weight and high manufacturing cost for the metal strip lamp holder 100. In this embodiment, the strip lamp holder 100 and the lampshade 500 are manufactured using two-color co-extrusion. The strip lamp holder 100 is opaque, while the lampshade 500 is translucent. Therefore, two-color co-extrusion can produce a circumferentially closed hollow lamp cavity 400, which is convenient to manufacture and has good waterproof performance. Two-color co-extrusion is a plastic profile extrusion processing method that refers to the process of feeding two different colored materials (which may be of different materials) through different flow channels to the extrusion equipment to produce a product with two different colors.

[0034] In this embodiment, the terminal cover 300 includes a power box 301 that is sealed to the mounting port 401 and a plug 302 that is sealed to the power box 301. Integrating the power box 301 into the terminal cover 300 can greatly simplify the lamp body structure and reduce manufacturing costs.

[0035] There are many ways to connect and seal the power supply box 301 to the mounting port 401. In this embodiment, the power supply box 301 includes: an outer box body 3011, a power circuit board 3013, an annular sealing groove 3015, and a sealing cavity 3014. The outer box body 3011 is open on one side facing the mounting port 401 and has a plug-in section 3012 extending into the mounting port 401; the power circuit board 3013 is disposed in the outer box body 3011; the annular sealing groove 3015 is disposed on the plug-in section 3012; the sealing cavity 3014 is disposed in the outer box body 3011 and has a first opening 3019 that abuts against the power circuit board 3013 and a second opening 3016 that communicates with the outer wall of the outer box body 3011. The output end of the plug-in 302 passes through the second opening 3016 and the first opening 3019 and connects to the power circuit board 3013. In this embodiment, the sealing structure of the terminal cover 300 is integrated into the power supply box 301, making the lamp body structure simpler and easier to manufacture. The plug section 3012 is similar in shape to the hollow lamp cavity 400 and fits against the inner wall of the hollow lamp cavity 400, thereby forming a sealing cavity between the inner wall of the hollow lamp cavity 400 and the annular sealing groove 3015.

[0036] Furthermore, the insertion section 3012 includes a rear insertion section 3112 and a front insertion section 3212. The rear insertion section 3112 extends from the outer casing 3011 toward the mounting port 401. The front insertion section 3212 is provided with the annular sealing groove 3015, with one end extending into the mounting port 401 and the other end extending into the rear insertion section 3112. This structure is easier to manufacture.

[0037] Furthermore, the front insertion section 3212 and the rear insertion section 3112 are snap-fitted together on their inner walls. Specifically, the rear insertion section 3112 has a slot 3312 on its inner side, and the front insertion section 3212 has locking blocks 3412 on both sides that engage with the slot 3312, making connection convenient and assembly easy.

[0038] Furthermore, the injection port 3017 of the annular sealing groove 3015 is located on the power supply box 301. This allows it to easily share an injection port 3017 with the sealing cavity 3014. Furthermore, the injection port 3017 is also connected to the sealing cavity 3014. Furthermore, the injection port 3017 is positioned abutting against the mounting port 401.

[0039] To improve the sealing effect, in this embodiment, the second opening 3016 is provided with a sealing element 3018, and the input end of the plug 302 passes through the sealing element 3018.

[0040] To ensure more complete glue injection and a better sealing effect, in this embodiment, the groove depth of the annular sealant groove 3015 in the region away from the glue injection port 3017 is greater than the groove depth near the glue injection port 3017. Since the glue is less likely to fill the region further away from the glue injection port 3017, this arrangement allows the glue to more easily fill the region away from the glue injection port 3017. Furthermore, the annular sealant groove 3015 includes a bottom 3113, two side portions 3213, and a top 3313, with the glue injection port 3017 located at the top 3313, and the bottom 3113 having the greatest groove depth.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions or improvements within the spirit of the present invention are covered within the scope of the claims of the present invention.
