Traditional ordinary lamps are difficult to meet the complex needs of nuclear power plants in terms of light source stability, radiation resistance and safety protection level. Therefore, linear LED lights, as an advanced lighting solution, have gradually taken a dominant position in nuclear environments such as nuclear power plants. This type of LED lamp not only has significant advantages such as high efficiency and energy saving, long life, and adjustable light color, but more importantly, they can be customized for the special environment of nuclear power plants to meet the high standards for protection performance, installation convenience and maintenance efficiency.

[0037] In order to solve the problem that the single lamp in the prior art cannot be quickly assembled and the irradiation range of the light source is limited, the present invention provides a spliced ​​strip LED lamp.

[0038] To achieve the above-mentioned purpose, the present invention proposes a spliced ​​strip LED lamp, which includes a plurality of LED lamp modules.

When more than two LED lamp modules 1 are provided, the outer ends of the two outermost LED lamp modules 1 are provided with a junction box 3, and the LED lamp modules 1 in the middle are electrically connected to each other through the connector 2.

Figure 2As shown, the LED lamp module 1 further includes a light source mounting plate 103, a light source 104, a mounting port 105 and a power module 106 arranged inside the housing 101. Mounting ports 105 are provided on the inner walls at both ends of the housing 101, and both sides of the light source mounting plate 103 are mounted in the two mounting ports 105. Two light sources 104 are obliquely arranged on the light source mounting plate 103, and the oblique directions of the two light sources 104 are arranged crosswise; the power module 106 can be a battery, which is arranged in the housing 101 and on the lower side of the light source mounting plate 103, and is used to supply power to the light source 104. The connecting piece 102 is located on the upper end surface of the shell 101, and two slide grooves 107 are provided on both sides of the shell 101. The connecting piece 102 is arranged in a door shape as a whole. The two free ends of the connecting piece 102 are bent inward to form an arc portion, and the arc portion is arranged in the slide groove 107, so that the connecting piece 102 can slide along the length direction of the shell 101, which is convenient for adjusting the position of the connecting piece 102. Bolt holes are provided on the connecting piece 102, which is convenient for connecting with external structural parts through bolts, facilitating maintenance and replacement, and preventing the LED lamp module 1 from falling.

The two side shells 201 have the same structure, and the two side shells 201 are connected to the two housings 101 of the adjacent LED lamp modules 1. The two side shells 201 can be quickly connected through the rotary joint 203, thereby realizing a quick assembly and rotation between two adjacent LED lamp modules 1. By rotating the rotary joint 203, the rotary joint 203 is allowed to enter the two side shells 201, and then the two side shells 201 are fixed again through the clamping mechanism 202 on the side of the side shell 201, so that the connection between the two side shells 201 is more stable and will not become loose or shaken due to vibration.

[0046] The rotary joint 203 includes a rotating plate 206 and connecting columns 207 and clamping blocks 208 on both sides thereof.

The two fixed blocks 211 are centrally symmetrical about the center of the circular hole. When the side shell 201 is connected to the rotary joint 203, the fixed blocks 211 can pass through the avoidance opening and then enter the clamping groove 209 by rotation.

Two side plates 216 are provided on the clamping plate 213, one end of the hinge 214 is rotatably connected to the two side plates 216, and mounting holes are provided on the two side plates 216. The two free ends of the hinge 214 are provided in the two mounting holes, and the other end of the hinge 214 is rotatably connected to the mounting seat 215. One end of the clamping plate 213 is provided with a second clamping portion 218, and the second clamping portion 218 cooperates with the first clamping portion 217. The two free ends of the hinge 214 can rotate in the mounting hole, and the other end of the hinge 214 can rotate relative to the mounting seat 215. The first clamping portion 217 and the second clamping portion 218 are both L-shaped, and the corners of the first clamping portion 217 and the second clamping portion 218 are arc-shaped, which facilitates the mutual engagement or separation between the first clamping portion 217 and the second clamping portion 218. By rotating the clamping plate 213, the clamping plate 213 rotates along a specific trajectory under the action of the hinge 214, and then drives the second clamping portion 218 to engage with the first clamping portion 217, so as to further fix the two side shells 201 and avoid loosening or shaking during vibration.

[0048] As a preferred embodiment, the connector 2 further includes a sealing ring 212, which is disposed on both sides of the rotary joint 203, and can achieve sealing between the rotary joint 203 and the two side shells 201, and can achieve a buffering effect.
