Claims

[Claim for Utility Model Registration] In a louver structure in which a plurality of flat horizontal louvers are inserted orthogonally and locked into a vertical louver with a V-shaped cross section, the vertical louver is V-shaped with horizontal louvers inserted at multiple locations at the bottom. a lower slit, and a pair of upper slits formed along the extension line of the lower slit at two locations apart from both ends of the lower slit, with the horizontal louver at the top and the vertical louver extending from both ends of the lower slit. An inverted trapezoidal notch is fitted up to the upper end of the upper slit, and a notch protrudes integrally from both ends of this notch and slides on the outer surface between the lower slit and the upper slit of the vertical louver to deform the vertical louver compressively and elastically. 1. A louver structure for a lighting device, comprising a pair of locking claws that are inserted into and engaged with a pair of upper slits.
