DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 8 As shown, the utility model provides the following technical solutions:

[0024] A device for adjusting the width of the light-emitting surface of a strip light source includes a lighting component for illuminating an object to be detected, the lighting component is symmetrically rotated toward one side of the object to be detected and is connected to two shielding components, and two motors 7 are fixedly connected to the lighting component, the output ends of the two motors 7 are respectively connected to the two shielding components, and a lighting area for light to pass through is formed between the two shielding components.

[0025] Through the above technical solution, when personnel need to install the device, the lighting component is fixed at the position required by the personnel, so that the lighting component is above the object to be detected. When personnel need to detect the object, the two motors 7 are used to drive the two shielding components to rotate respectively, and then the angles of the two shielding components are adjusted, thereby adjusting the area where the lighting component emits light. The lighting component works and then allows the lighting component to emit light to illuminate the object, thereby assisting personnel in detecting the object.

[0026] Specifically, in one embodiment, regarding the above-mentioned lighting element, as Figure 1-Figure 2 and Figure 5 As shown, the lighting component includes a housing 1 , the bottom of the housing 1 is recessed to form a mounting groove 16 , and a strip LED light 15 is fixedly connected inside the mounting groove 16 .

[0027] In this embodiment, after the housing 1 is fixed at the position required by the personnel, the strip LED light 15 is installed through the installation groove 16 on the housing 1. The strip LED light 15 emits light to fill in the object, thereby assisting the personnel in inspecting the object.

[0028] Specifically, in one embodiment, regarding the above-mentioned shielding member, as Figure 1-Figure 2 , Figure 4 , Figure 6-Figure 8 As shown:

[0029] The shielding member includes shading plates 8 , and two shading plates 8 are symmetrically rotatably connected to the bottom of the housing 1 .

[0030] In this embodiment, when personnel need to adjust the lighting surface, the motor 7 drives the shading plate 8 to rotate, thereby adjusting the angle of the shading plate 8, and the shading plate 8 blocks the light emitted by the strip LED light 15, thereby adjusting the light emitting area of ​​the strip LED light 15.

[0031] In addition, in the present invention, when the shading plate 8 blocks the light emitted by the lighting element, in order to prevent light leakage, Figure 7-Figure 8 As shown, the tops of the two shading plates 8 are both bonded with foldable soft covers 5 , and the tops of the foldable soft covers 5 are bonded to the top of the housing 1 .

[0032] In this embodiment, when the sunshade 8 rotates, the foldable soft cover 5 is simultaneously stretched, so that the foldable soft cover 5 is unfolded, thereby shielding the sunshade 8 around and preventing light from leaking from around the sunshade 8.

[0033] In order to adjust the width of the light-emitting surface of the strip LED lamp 15 in real time, Figure 1-Figure 2 As shown, the outer shell 1 is fixedly connected to side panels 12 on both symmetrical sides, the bottoms of the two side panels 12 are rotatably connected to rotating rods 11, the free ends of the rotating rods 11 are fixedly connected to the ball head 6, one side of the ball head 6 is rotatably connected to a connecting head 10, and the side of the connecting head 10 away from the ball head 6 is fixedly connected to a detection camera 9.

[0034] In this embodiment, when it is necessary to adjust the width of the light-emitting surface of the strip LED lamp 15, the connecting head 10 is pulled to rotate the connecting head 10 relative to the ball head 6, and then the rotating rod 11 is rotated relative to the side panel 12, and then the position of the detection camera 9 is adjusted. The light-emitting effect of the strip LED lamp 15 is adjusted by the detection camera 9 in real time, and the image information is transmitted to the system control unit (not shown in the figure). The system control unit analyzes the image information to determine whether the current light-emitting surface width meets the requirements. If the width needs to be adjusted, the system control unit sends an instruction to the motor 7, and the motor 7 drives the shading plate 8 to rotate, thereby changing the light-emitting surface width of the strip LED lamp 15.

[0035] In addition, in the present invention, when the strip-shaped LED lamp 15 generates heat during operation, in order to improve the heat dissipation efficiency of the strip-shaped LED lamp 15, as shown in FIG. Figure 1-Figure 3 As shown, a heat conducting plate 14 and two mounting plates 3 are fixedly connected to the top of the housing 1, the heat conducting plate 14 is located between the two mounting plates 3, a through-type mounting cavity 4 is provided on the mounting plate 3, a guide fan 2 is installed inside the mounting cavity 4, a through-type guide hole 13 is provided on the heat conducting plate 14 along the blowing direction of the guide fan 2, and the bottom of the heat conducting plate 14 extends to the inside of the mounting groove 16.

[0036] In this embodiment, when the strip LED lamp 15 generates heat during operation, the heat is conducted through the heat conducting plate 14, and the guide fan 2 is supported by the mounting plate 3. The guide fan 2 works to guide the airflow through the mounting cavity 4, so that the airflow blows toward the guide holes 13 on the heat conducting plate 14, thereby accelerating the heat dissipation of the heat conducting plate 14, thereby accelerating the heat dissipation performance of the strip LED lamp 15.
