Detailed Description

The specific implementation contents are described in conjunction with the attached drawings and the application examples of the present invention. As shown in fig. 1 and 2, the light source device based on the different fiber sorting machine includes two groups of lighting devices with the same structure, and the two groups of lighting devices are oppositely installed and respectively installed on the left side and the right side of the detection channel. The two groups of lighting devices can simultaneously meet the requirement that the two linear array cameras collect cotton pictures, so that the occupied space of the two camera light paths is reduced by half.

The lighting device comprises a lamp holder 1, a high-brightness full-spectrum LED lamp tube 2, a background plate 3, a rotatable lamp foot frame 4 and an adjustable support 5. The LED fluorescent lamp comprises a lamp bracket 1 and is characterized in that two high-brightness full-spectrum LED lamp tubes 2 which are vertically arranged are installed on the lamp bracket 1, a background plate 3 is arranged between the two high-brightness full-spectrum LED lamp tubes 2, the high-brightness full-spectrum LED lamp tubes 2 are installed on the lamp bracket 1 through rotatable lamp foot stands 4, and the background plate 3 is installed on the lamp bracket 1 through an adjustable support 5.

The two high-brightness full-spectrum LED lamp tubes 2 are distributed on the upper side and the lower side of the background plate 3 in parallel and used for irradiating the detection channel. The background plate 3 is located between the two high-brightness full-spectrum LED lamp tubes 2 and is close to the high-brightness full-spectrum LED lamp tube on the upper side, the high-brightness full-spectrum LED lamp tube on the upper side is used for supplementing light for the background plate 3, and the brightness of the background plate 3 is changed by rotating the high-brightness full-spectrum LED lamp tubes 2 and adjusting the distance between the background plate 3 and the full-spectrum LED lamp tubes 2. The height of the background plate 3 is adjusted through the adjustable support 5, and then the distance between the background plate 3 and the full-spectrum LED lamp tube 2 can be adjusted.
