[0021] The following is combined with Figure 1 To the attached Figure 5 The principles and features of the present invention are described, and the examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] An inspection lamp includes a shell 1, a lens group 2 and a control module 3 arranged in the shell 1. The lens group 2 is installed in the shell 1 through a support plate 8. The lens group 2 can be installed near the middle position of the shell 1. The control module 3 is installed on the inner wall of the shell 1.

[0023] The lens group 2 includes a lens barrel 20, an LED lamp bead 21, a spherical lens 22, a plurality of semi-elliptical lenses and a light shield 26, wherein the LED lamp bead 21 is electrically connected to the control module 3. In one embodiment, three semi-elliptical lenses are provided, that is, the lens group 2 includes a lens barrel 20 and an LED lamp bead 21, a spherical lens 22, a first semi-elliptical lens 23, a light shield 26, a second semi-elliptical lens 24, and a third semi-elliptical lens 25 coaxially arranged in the lens barrel 20. Wherein, a light transmission port 27 is provided on the light shield 26. When the light source passes through the first semi-elliptical lens 23, scattered light may occur. The light shield 26 can better prevent astigmatism. In one embodiment, the light transmission port 27 is square. By arranging the spherical lens 22, the light source is focused. By arranging the first semi-elliptical lens 23, the second semi-elliptical lens 24 and the third semi-elliptical lens 25, the light source is defocused, and the illumination area of ​​the LED lamp bead 21 is finally amplified, and the light source passing through the lens group 2 is made uniform and stable. A plurality of heat dissipation slots 28 are further provided on the outer wall of the lens barrel 20 for dissipating heat from the lens barrel 20 .

[0024] The sidewalls of the housing 1 are equipped with a knob 4, a cooling fan 5, a barrel hole 6, and a power socket 7. These knobs, cooling fan 5, and power socket 7 are electrically connected to the control module 3. The knob 4 is used to adjust the light intensity of the LED lamp 21, and the cooling fan 5 is used to check the overall heat dissipation of the lamp. One end of the lens barrel 20 extends out of the housing 1 through the barrel hole 6, with the third semi-elliptical lens 25 positioned closer to the barrel hole 6.

[0025] To accommodate a wider range of usage scenarios, the housing 1 can be configured as either a floor-standing or wall-mounted version. Legs 11 are provided on the bottom wall of the housing 1 for floor-standing use, and wall-mounted components 12 are provided on the side walls of the housing 1 for wall-mounted use.

[0026] The wall-mounting assembly 12 includes a sleeve rod 13, a base 14, an adjustment rod 15, and a sleeve that can be mounted on the sleeve rod 13. The sleeve rod 13 is movably connected to the base 14, and the adjustment rod 15 is threadedly connected to the base 14 for adjusting the height of the sleeve rod 13. When in use, the sleeve is fixedly installed at the location where the inspection light is to be wall-mounted, and then the sleeve rod 13 is inserted into the sleeve.

[0027] In one embodiment, an auxiliary light 9 is further provided on the outer wall of the housing 1 . The auxiliary light 9 is provided adjacent to the cylindrical hole 6 and is used to assist in inspecting defects of the lens assembly 2 .
