As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its role in the solution of the utility model.

[0034] Example 1

[0035] like Figure 1 As shown, an integrated linear light source system includes a linear light source 1, a controller 2 and a copper busbar 3.

[0036] The line light source 1 includes a plurality of LED light panels 11. The light emitted by the line light source 1 can be irradiated to the inspected object for defect detection. Furthermore, the length of the line light source 1 can reach 2-6m to meet the inspection requirements of long and large products.

[0037] The controller 2 is fixed to one end of the line light source 1. In this embodiment, the controller 2 is fixed to the bottom surface of the line light source 1. The controller 2 may be integrated with a DC power supply, and the line light source 1 may be directly powered by the controller 2. Furthermore, the controller 2 may also be integrated with a control panel, a drive panel, etc.

[0038] One end of the copper bar 3 is connected to the controller 1, and the other end of the copper bar 3 extends along the length direction of the linear light source 1 and is connected to the plurality of LED light boards 11. That is, the copper bar 3 can simultaneously connect the plurality of LED light boards 11.

[0039] Therefore, by setting the copper busbar 3 along the length direction of the linear light source, the controller 2 can directly supply power to the linear light source 1, so that the light source installation site is improved from many cables to one power line, which is safe and reliable. By setting the copper busbar 3 along the length direction of the linear light source, the multiple LED light panels 11 can be connected to the power supply through the copper busbar 3, which can solve the problem of lamp bead pressure difference and ensure that the brightness consistency from the first lamp bead to the last lamp bead reaches more than 90% uniformity, providing a guarantee for obtaining consistent image brightness.

[0040] In a preferred embodiment, the copper busbar 3 can be connected to all the LED lamp boards 11, thereby further reducing the voltage difference of all LED lamp beads.

[0041] In a preferred embodiment, the copper busbar 3 can be arranged along the length direction of the linear light source 1, and the length range of the copper busbar 3 can cover the length range of the linear light source 1, so that the LED light panels 11 can be connected to the power supply through the copper busbar 3, thereby further reducing the voltage difference of all LED lamp beads.

[0042] In a preferred embodiment, the copper busbar 3 is connected to the LED light board 11 through a wire, so as to realize the electrical connection between the LED light board 11 and the copper busbar 3. Figure 3 In other embodiments, the copper busbar 3 may also directly contact the positive and negative contact blocks of the LED lamp board 11 .

[0043] In a preferred embodiment, the number of the copper bars 3 is two, one of which is connected to the positive electrode of the power supply, and the other is connected to the negative electrode of the power supply, that is, the positive copper bar 31 and the negative copper bar 32. Figure 2 shown.

[0044] In a preferred embodiment, the line light source 1 further includes a Fresnel lens plate 12, which is arranged on the light-emitting side of the line light source 1, and the light emitted by the LED light board 11 is emitted to the Fresnel lens plate 12. The use of the Fresnel lens 12 can greatly improve the light-emitting efficiency of the line light source and increase the illumination of the working surface to a maximum of 10 million LUX.

[0045] Furthermore, the line light source 1 may further include a light modifier 13, the Fresnel lens plate 12 and the light modifier 13 are sequentially arranged on the light-emitting side of the line light source 1, and the light emitted by the LED light board 11 sequentially reaches the Fresnel lens plate 12 and the light modifier 13 and then exits. By arranging the light modifier 13, the control capability of the light can be further improved, thereby meeting different detection light requirements.

[0046] like Figure 4 As shown, in some implementations, the light modifier 13 is a single polarization light modifier, which can achieve unidirectional deflection of light, thereby meeting the corresponding detection scene requirements.

[0047] like Figure 5 As shown, in some implementations, the light modifier 13 is a dual-polarization light modifier, which can achieve bidirectional deflection of light, thereby meeting the requirements of corresponding detection scenarios.

[0048] Furthermore, the linear light source 1 may further include a radiator to meet the heat dissipation requirements of the light source. The radiator may be water-cooled or air-cooled.

[0049] Example 2

[0050] like Figure 6As shown, the difference between this embodiment and embodiment 1 is that the controller 2 in this embodiment is fixed to the side of the linear light source 1 .

[0051] Example 3

[0052] A detection system includes an image acquisition device and an integrated line light source system as described in Example 1 or Example 2.

[0053] The utility model provides a detection system, which can obtain relatively consistent image brightness by setting the above-mentioned integrated line light source system, thereby improving the efficiency of defect detection.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
