Keksintö koskee rasterivalaisinta, jossa on ainakin kaksi pitkittäisle-vyä, jotka on sijoitettu symmetrisesti valaisimen keskiviivaan nähden kunkin vastaavan, lampun alapuolelle ja joilla on oleellisesti tasainen profiili.The invention relates to a grid luminaire having at least two longitudinal plates arranged symmetrically with respect to the center line of the luminaire below each corresponding lamp and having a substantially flat profile.

Tällaisissa valaisimissa, joissa on kaksi tai useampia lamppuja, on pitkittäislevyt samoin kuin rasterin poikittais levyt sijoitettu pystysuorasti valaisimen asennusasexmosea. Tästä seuraa valon tiheyden epätasainen jakaantuminen, josta on se seuraus, että rasterin ulommat alueet esiintyvät pimeämpi-nä kuin sisemmät. Keksinnön tehtävänä on siksi kehitellä edelleen mainitunlaista valaisinta siten, että saavutetaan valon tiheyden mahdollisimman yhdenmukainen jakaantuminen rasterin sisällä.In such luminaires with two or more lamps, the longitudinal plates as well as the transverse plates of the raster are arranged vertically in the mounting axis of the luminaire. This results in an uneven distribution of light density, with the consequence that the outer areas of the raster appear darker than the inner ones. The object of the invention is therefore to further develop such a luminaire so as to achieve the most uniform distribution of light density within the raster.

Tämän tehtävän keksinnön mukainen ratkaisu tunnetaan mainitunlaisessa rasterivalaisimessa siitä, että pitkittäislevyt muodostavat pystytasojen kanssa alhaalla avoimen, terävän kulman.The solution according to the invention for this object is known in such a raster lamp in that the longitudinal plates form an open, sharp angle at the bottom with the vertical planes.

Keksinnön mukainen vaikutus johtuu siitä, että valovirta, joka heijastuu vinosti asetetusta pitkittäislevystä poikittaislamelleihin, kasvaa pit- kittäislevyn ulkopuolella ja pienenee sen sisäpuolella.The effect according to the invention is due to the fact that the luminous flux reflected from the obliquely placed longitudinal plate to the transverse lamellae increases outside the longitudinal plate and decreases inside it.
