And combines the floodlight cover 30 having a curved portion 32 for transmitting the light of the LED 23 to the intermediate plate 20,
Expanded on the upper portion of the floodlight cover 30 to form a downward inclined expansion inclined portion 31 so that the light reflected from the curved portion 32 can be irradiated backward through the expansion inclined portion 31,
An extension 11 is formed at the lower end of the housing 10, and a plurality of light transmission grooves 12 are formed in an annular shape on the extension 11 so that light passing through the expansion inclination portion 31 passes through the light transmission groove 12. ) So that it can be irradiated backward through
The concave lens 41 is formed by rotating the rotating plate 40 by rotatably installing a ring-shaped rotating plate 40 at the lower end of the housing 10 in which a plurality of concave lenses 41 and convex lenses 42 are alternately installed. Or convex lens 42 is positioned in the light-transmitting groove 12 so as to spread the light irradiated to the rear or to gather in one place,
LED illuminating device that can be used as a lantern or indoor light, characterized in that formed on the edge of the intermediate plate 20 to support the rotating plate 40 rotatably protruding outwardly. 삭제delete
