Abstract

The invention relates to a control cabinet light for illuminating a control cabinet interior, wherein the control cabinet light comprises a light base member which holds an illuminating means of the control cabinet light and a transparent illuminating means cover mounted at the light base member, said cover transparently surrounding the illuminating means, characterized in that the illuminating means cover has two transparent separated parallel sides between which the illuminating means is disposed when the illuminating means cover is placed on the light base member, wherein the illuminating means comprises a flat illuminating means plate on which a plurality of individual illuminating means, in particular LEDs or OLEDs, are distributed, and wherein the illuminating means plate extends parallel or at an angle of more than 0°, in particular less than an angle of about 45°, relative to the parallel sides of the illuminating means cover.

First claim

The invention claimed is:

1. A control cabinet light for illuminating a control cabinet interior, wherein the control cabinet light comprises a light base member which holds an illuminating means of the control cabinet light and an illuminating means cover mounted at the light base member, said cover transparently surrounding the illuminating means, wherein the illuminating means cover is designed to be U-shaped in cross section perpendicular to the longitudinal direction thereof, with two transparent separated parallel sides between which the illuminating means is disposed when the illuminating means cover is placed on the light base member, and with a further side connecting the separated parallel sides, wherein the illuminating means cover is configured to be mounted in two positions on the light base member, the positions being rotated relative to one another by 180° about an axis transverse to the longitudinal direction, wherein the illuminating means comprises a flat illuminating means plate on which a plurality of individual LEDs or OLEDs, are distributed, and wherein the illuminating means plate extends parallel to the parallel sides of the illuminating means cover, wherein a reflector extends along the inside or the outside of one of the two parallel separated sides, so that the reflector has a different orientation relative to the illuminating means in the two positions of the illuminating means cover which are rotated by 180° relative to one another, whereby light emitted from the illuminating means is reflected back into the control cabinet interior by the reflector.

2. The control cabinet light according to claim 1 , in which the light guide extends parallel to the side associated therewith and thus perpendicular to the rotation plane or is at an angle relative to the side associated therewith.

3. The control cabinet light according to claim 1 , in which the the illuminating means cover is connected to the light base member by way of a fastener, designed as a tongue and groove connector, at each of the free longitudinal edges of the parallel sides of the illuminating means cover by way of which the illuminating means cover is placed onto the light base member.

4. The control cabinet light according to claim 1 , in which the transparent illuminating means cover, in particular at least one of the two parallel sides is designed at least in sections as a planar-convex lens or a Fresnel lens, wherein a convex side of the planar-convex lens or a stepped structure of the Fresnel lens is designed at an inside of the illuminating means cover facing the illuminating means.

5. The control cabinet light according to claim 4 , wherein at least one of the separated parallel sides of the illuminating means cover can be designed as the planar-convex lens or the Fresnel lens, wherein the at least one separated parallel side with the planar-convex lens or Fresnel lens is designed as planar and/or unstructured on an outside of the illuminating means cover which faces away from the illuminating means.

6. The control cabinet light according to claim 4 , wherein the illuminating means can be a directed light source, in particular a light source comprising a plurality of LEDs and/or OLEDs, so that the transparent illuminating means cover, which is designed at least in sections as a planar-convex lens or a Fresnel lens, is a diverging lens.
