Luminaire louvre for an elongated lamp

摘要

In a luminaire louvre for a luminaire having elongated lamps, in particular a specular louvre, two mutually inclined, parabolic reflector plates 2 are connected at right angles by louvre webs 1 which have a V-shaped cross-section and are plugged through perforations 21, matched in shape, in the reflector plates 2. In the upper edge region of their limbs 11 and 12, the louvre webs 1 have incisions 17 into which projections 21e on the upper edges of the perforation 21 engage. Likewise provided at the apex 13 of each louvre web 1 is an incision 18 into which the lower edge 21c of the perforation 21 engages in each case. The outer sections 171 of the web limbs 11 and 12 are offset in this case up to their incision 17 with respect to the upper edge 11 or 121. The connection between the louvre webs and the outer reflectors is improved in this way. <IMAGE>
