  • it is provided in the center of the annular portion 61. It is good also as what attaches to the state which locked the opening edge 31a of the glare cut cap 30 by the fixing nail
  • the mounting jig 60 is supported between the stepped portion 46 formed on the inner periphery of the casing 40 and the distal end of the insertion portion 51 formed on the upper end of the cone 50.
  • the fixing method of the mounting jig 60 in the casing 40 is limited to the above example.
  • various modifications such as forming the lower end portion of the casing 40 to be receivable on the upper end side of the cone 50 are possible.

Abstract

La présente invention se rapporte à un chapeau anti-éblouissement et à un équipement d'éclairage équipé du chapeau anti-éblouissement, qui utilisent efficacement la lumière directe régulière provenant d'une source de lumière qui a été interrompue de manière classique par le chapeau anti-éblouissement comme lumière d'éclairage. Un chapeau anti-éblouissement (30) se compose d'un matériau de transmission de lumière et est façonné selon une forme pour servir de lentille ou de prisme afin de commander la lumière qui entre à l'intérieur du chapeau anti-éblouissement par une ouverture (31) par diffusion, convergence, dispersion et/ou réfraction de la lumière dans un état prescrit lorsque la lumière le traverse. Le chapeau anti-éblouissement (30) est monté sur la partie d'extrémité d'une source de lumière (10) dans un équipement d'éclairage (1) qui comprend la source de lumière (10), et un réflecteur (20) qui réfléchit la lumière provenant de la source de lumière (10) afin d'émettre la lumière vers l'avant, de sorte qu'un bord d'ouverture (31a) soit positionné sur une ligne (γ) qui s'étend depuis une extrémité supérieure (β) sur la surface intérieure d'un cône (50) de manière à être en contact avec la surface extérieure d'un élément émetteur de lumière (α) dans la source de lumière (10).
