Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides the following technical solutions: the utility model provides a show lighting device for exhibition, which comprises an outer shell 1, the internally mounted of shell 1 has bulb 12, annular slope 10 is installed to the inner wall of shell 1, spout 71 has been seted up to the bottom of annular slope 10, lens 6 is installed to the below of annular slope 10, slide bar 7 is installed to one side of lens 6, shell 1 one side is run through to the one end of slide bar 7, limiting plate 4 is installed to slide bar 7 one end, the top of limiting plate 4 is connected with pull rod 2, annular slope 10 need be the transparence, annular slope 10 is used for preventing that the insect corpse from gluing on the lateral wall, lens 6 are provided with four altogether, limiting plate 4 is used for restricting slide bar 7.

Further, pivot 9 is installed to the bottom of shell 1, is connected with light screen 8 in the pivot 9, installs reflector layer 81 on the light screen 8, and pivot 9 is the annular shape, and light screen 8 rotates through pivot 9, and reflector layer 81 is used for reflecting the light that bulb 12 came out.

Furthermore, the upper limiting block 3 is installed above the limiting plate 4, the lower limiting block 5 is installed below the limiting plate 4, the limiting plate 4 is limited on the outer wall of the shell 1 by the upper limiting block 3 and the lower limiting block 5, and the pull rod 2 penetrates through the upper limiting block 3 and is connected with the limiting plate 4.

Specifically, the shell 1 is internally provided with a reflecting cup 11, the bulb 12 penetrates through the reflecting cup 11, and the reflecting cup 11 is used for concentrating light rays to be emitted to a lamp opening.
