In addition, according to the dome-shaped heat ray detector of the present invention, the annular plate portion and the cover portion of the worm penetration preventing member have an effect of preventing the insect from entering the lens from the hole and power connector for fixing the base member to the ceiling.

An embodiment of the present invention described above and illustrated in the drawings should not be construed as limiting the technical idea of the present invention. The protection scope of the present invention is limited only by the matters described in the claims, and those skilled in the art can change and change the technical idea of the present invention in various forms. Therefore, such improvements and modifications will fall within the protection scope of the present invention, as will be apparent to those skilled in the art.
