LED fluorescent powder brightness detection device

Mode of execution

In order to make the technical means, the creation feature, the achievement object and the effect of the utility model easy to understand, the utility model is further elucidated below in connection with the specific embodiments and the accompanying drawings. Based on the embodiments in the embodiments, other embodiments can be obtained by those skilled in the art without creative efforts, and belong to the protection scope of the present disclosure.

Specific embodiments of the present invention will be described below with reference to the drawings.

As 1-2 shows a LED fluorescent powder brightness detection device, which comprises a base 9, a base 9 is made of plastic material, a cover plate 9 is arranged above the base 8, and two observation barrels 8 are fixedly arranged on the top surface of the base 5.5. The observation lens 4 is fixedly arranged above the bottom surface of the detection post 4 through a fixing rod 2 and a limiting plate 4 fixedly arranged in the bottom surface of the observation cylinder 3 and fixedly connected with the bottom surface of the base plate 3 through a fixing 12 rod. The 17 bottom surface 17 of the detection post is fixedly provided with two 12 1 detection posts 9, and the bottom 9 15 surface of the base 10 is fixedly provided with a plurality of support rods second 9 18 18 second which 9 are fixedly provided with grooves 12 arranged on 16 the bottom surface of the bottom plate of the bottom plate of the base plate.

The bottom of cylinder 8 is fixedly provided with two connecting blocks 13, the bottom of connecting block 13 is vertically fixed with inserting rod 14, and inserting rod 14 and base 9 are inserted into and matched with each other.

The top surface of the cylinder 8 is fixedly provided with a sliding block 6 at the left and right ends, a sliding groove 5 is arranged on the bottom surface of the cover plate 11, and the sliding block 6 is slidably connected in the sliding groove 11.

After insertion, the detection post 12 is fixed, the two eyes are aligned to the top surface LED fluorescent powder of the detection column 12 12, and the LED fluorescent powder and 9 the standard LED fluorescent powder sample obtained by sampling are 15 aligned, and whether 16 the brightness of LED fluorescent powder 12 acquired by sampling accords with a predetermined value or 4 not is determined 12.

By moving the cover plate 11 along the chute 5, the position of the viewing tube 4 can be adjusted so that the top of the detection column 12 is more accurately aligned.

The basic principle, main characteristics and the utility model of the utility model are shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, but is merely a preferred example of the present invention and is not intended to limit the present invention. The scope of the claimed invention is defined by the appended claims and their equivalents.
