Description

The The invention relates to a desk lamp with a base and a light source having a light head.

at such a desk lamp is a floor lamp, with their footprint, e.g. placed on the table top of a desk or the like becomes. The luminous head is connected to the base by means of a column element connected. This pillar element may be rigid or yielding to adjust the light head as desired to be able to.

such Desk lamps are available in a variety of different designs on the market.

Of the Invention is based on the object, a desk lamp of above-mentioned way of creating a new, elegant shape has.

These The object is achieved by the Features of claim 1, i. solved by the fact that with the stand the head connected by means of a housing body is that as curved rigid pillar with a square outer contour is formed, wherein the light head is integrated into the housing seamlessly and the light source provided in the light source by touching the Housing body (touch function) can be switched on and off.

The inventive desk lamp has So no on / off switch. The curved rigid pillar is expediently surface finish. In this surface refinement it can be e.g. act around a chrome plating, so that is a elegant design results.

at the desk lamp according to the invention has the curved Column preferably a concave arcuate curved palm and a convex arcuate curved Outer surface and two plane connecting the inner and outer surface faces on. Here is the curvature the inner surface preferably greater than the curvature of the Outer surface. The curvature the inner surface and the curvature the outer surface can each have one constant radius of curvature own, i. the arcuate palm and the arcuate outer surface are then so circular arc curved. The centers of curvature in such a way designed inner and outer surface fall not together; the center of curvature the outer surface is located below the center of curvature the inner surface and is laterally offset against this.

When has appropriate it turned out, if at the footprint of the desk lamp according to the invention an anti-slip coating is provided.

The inner end face of the base of the curved column can with the center of curvature the arched one Inner surface, i.e. the perpendicular through this center of curvature, congruent be provided, and the center of curvature the circular arc Outside surface is located laterally outside these perpendiculars and - like already executed has been under the center of curvature the circular arc Inner surface.

At the outer surface of the curved Pillar is preferably in the vicinity of the stand a connection socket for a Plug provided a power supply.

When has appropriate it is the desk lamp according to the invention proven when the light head is a circuit board with a the light source having forming LED. Such a LED has a very low Energy consumption with an extremely long service life. The light intensity or luminance the LED is for illuminating the workplace, for example one Desk adequate.

When has appropriate it turned out, when the case or the luminous head has a light opening, attached to the one of the light source associated lens is. This light panel can be assigned to the light source central transparent surface area and at least one surrounding translucent surface area exhibit. Appropriately it may be, if at the central transparent surface area a first translucent area and on these outside a second translucent surface area adjoins, wherein the translucency of the second surface area is smaller than the translucency of the first surface area. The / each translucency can be affected by a corresponding turbidity or Roughening the light panel be realized.

Further Details, features and advantages will be apparent from the following Description of an embodiment shown in the drawing the desk lamp according to the invention.

It demonstrate:

1 in a side view of an embodiment of the desk lamp, which is shown cut open in the region of its head, and

2 in sections, a view in the direction of arrow II in 1 ,

1 shows a side view of an embodiment of the desk lamp 10 standing between her stand 12 and her light head 14 a housing body 16 has, as a curved rigid column 18 is formed, which has a quadrangular outer contour throughout its entire longitudinal extent. This outer contour is characterized by a concave arcuate inner surface 20 and by a convex arcuate outer surface 22 and through two the surfaces 20 and 22 connecting flat side surfaces 24 (see also 2 ) certainly. The curvature of the inner surface 20 is greater than the curvature of the outer surface 22 , The center of curvature of the circular arc-shaped inner surface 20 is in 1 with M1 and the center of curvature of the circular outer surface 22 is designated M2.

The desk lamp 10 is designed such that the inner edge 26 the stand area 12 and the center of curvature M1 of the inner surface 20 in the vertical lines represented by a dashed line 28 aligned with each other. Of course, the stand space 12 be larger, to further minimize the risk of tipping over.

The center of curvature M2 is below the center of curvature M1, which is indicated by the arrow 30 is indicated, and laterally outside the vertical 28 , what by the arrow 32 is indicated. Of course, it is also possible with respect to the center of curvature M2 to position it differently. Of importance is only that the desk lamp 10 with their stand space 12 has sufficient stability.

At the booth 12 the desk lamp 10 is an anti-slip coating 34 intended.

On the outer surface 22 the curved column 18 is in the neighborhood of the stand area 12 a connection socket 36 provided for a plug of a power supply unit. The connection socket 36 is with one in the light head 14 isolated circuit board 38 electrically connected. The corresponding connection line is with the reference numeral 40 designated. On the board 38 is as a light source 42 an LED 44 intended. By touching the desk lamp 10 (Touch function) it can be switched on and off.

The housing body 16 ie the curved column 18 , is at her from the stand area 12 distant end with a light aperture 46 formed, at the one of the light source 42 associated light disk 48 (see also 2 ) is attached. As the 2 further clarified, the light-emitting pane 48 one of the light source 42 associated central transparent surface area 50 , one to the central transparent surface area 50 adjacent first translucent surface area 52 and a second translucent surface area adjoining this on the outside 54 on, wherein the translucency of the second surface area 54 is smaller than the translucency of the first surface area 52 ,

The detachable fastening of the light panel 48 at the light opening 46 of the housing body 16 For example, by threaded pins 56 putting one in the lens 48 sunken screw head 58 exhibit.
