Definitions

  • the invention relates to a lamp, according to the preamble of claim 1, as well as its production and a corresponding method.
  • the invention particularly relates to lights in the form of wall or ceiling lights for assembly or self-assembly - often referred to as permanent installation - as these occur very frequently in the private and commercial sectors, especially indoors.
  • the new light can also be used as a pendant light.
  • ecology is also playing an increasingly important role. The production of light itself has improved significantly with the advent of LEDs in terms of ecology, but the lights themselves and their production in terms of ecology - especially with regard to the materials used - made little progress, if not even regression.
  • WO 17/029147, CN 212430635 or AT 14025 U1 show various known lights, which, however, all have very complex structured light bodies made of many materials, which are complex to manufacture and also have a poor ecological footprint.
  • CN 208720015 U shows a round ceiling light that can be opened or closed in a slot by sliding the lampshade sideways.
  • the assembly of the luminaire during production and/or assembly at the customer's site is also often complex and expensive.
  • the object of the present invention is therefore to create a lamp that does not have the aforementioned disadvantages and is associated in particular with an improved ecological footprint and lower CO2 emissions with otherwise good lighting properties and sufficient stability and yet with distinctive individuality.
  • a large amount of recycling material should also be used, preferably in the form of available semi-finished products.
  • a simple customization of color and design is also a special task in order to reduce the necessary production variety.
  • a lamp is provided.
  • a lamp for (fixed) mounting on a ceiling or a wall for example a ceiling lamp or a wall lamp for (residential/work) room lighting, which is firmly and permanently mounted on a wall or ceiling, for example screwed.
  • functional lights such as emergency lights, emergency exit lights, etc. can also be designed according to the invention.
  • the lamp has a flat LED lamp insert, which emits visible light, preferably white but optionally also colored light, for example with an intensity of 100 to 5,000 lumens, so that it can be used for room lighting.
  • This can, for example, be formed with a plurality of LEDs distributed in one plane, such as a PCB (printed circuit board) equipped with LEDs or one or more LED strips (LED strips, LED light strip, flex LED) glued to a carrier plate -Strips, LED bar, LED brick), or in another embodiment also a holder for at least one standard/norm light source.
  • the light insert can also have an internal or (eg as a transformer module) external electronic control circuit for operating the LEDs on a supply voltage.
  • the supply voltage can in particular be a mains voltage, with the lighting insert being equipped with appropriate protection against accidental contact for mains voltage-carrying parts, but also a low voltage, for which protection against accidental contact is not absolutely necessary.
  • the lamp can alternatively be designed as a mobile lamp rather than a permanently installed one, optionally also with a battery or a rechargeable battery to provide the supply voltage, so that the lamp can also be used independently of the presence of electrical wiring and/or temporarily at several locations .
  • the control circuit can also have a switching or/dimmer device, optionally via a radio connection (e.g. ZigBee, Bluetooth, WLAN, etc.) or bus connection (e.g. installation tion bus, etc.) so that the light can be controlled individually or in a group without additional/special wiring.
  • a radio connection e.g. ZigBee, Bluetooth, WLAN, etc.
  • bus connection e.g. installation tion bus, etc.
  • the lamp also has a lamp body, e.g. in the form of a lamp cover.
  • the lamp body provides an improved, e.g. glare-free, homogeneous, etc. light distribution, protects the lamp insert and provides an aesthetic appearance of the lamp, which is preferably flexible or even individually designable/adaptable to the environment.
  • the lamp body can be designed in such a way that it encloses the lamp insert in the installed state, preferably completely, or forms a closed volume with the lamp insert, e.g. so that no insects or dirt can penetrate the lamp.
  • the lamp body is designed with a lamp frame, which in the mounted state preferably completely surrounds the lamp insert, and is connected to a translucent lamp pane, which is arranged on the lamp frame and is preferably permanently mounted in one piece with the lamp frame.
  • the light from the light insert can be radiated or distributed outwards with the light disc, preferably according to a desired emission characteristic of the light, for example essentially homogeneously over a defined angular range or according to another application-specific directional characteristic, glare-free, etc.
  • the light disc is preferably an opaque, opal or satined lamp pane (colloquially also referred to as "frosted glass").
  • the lamp pane When the lamp body is mounted on the lamp insert, the lamp pane is essentially parallel and spaced (eg a few millimeters to a few centimeters) from the lamp insert.
  • the lamp pane is preferably arranged within the lamp frame, ie, for example, the edges of the lamp pane are completely surrounded by the lamp frame, so that these two form a single piece in a safe and stable manner are connected or, after production, are inextricably connected to one another, at least for the user, preferably without the use of adhesives.
  • the lamp pane with the lamp frame can form a closed shell as the lamp body, in particular as a cavity open on one side (towards the lamp insert).
  • the lamp body and the lamp insert are designed in such a way that the lamp frame encloses the lamp insert in the assembled state, or is closed by the lamp insert.
  • the lamp frame is made from cardboard or cardboard, for example from wrapping cardboard, preferably from recycled cardboard/cardboard, for example from at least 60% or 80% or almost 100% or 100% recycled cardboard.
  • the lamp can be manufactured easily and sustainably and its CO2 balance or ecological footprint can be improved.
  • each lamp is unique, since recycled cardboard is never completely identical throughout its production due to the wide variety of starting materials. This also leads to an individual light emission. With good lighting quality, a major contribution to environmental protection can be made, among other things, because the luminaire itself consists of many parts from recyclable material, which can also be easily separated from each other and thus directly recycled. For example, at the end of the service life, the end customer can press the lamp cover out of the lamp frame and separate recycling is possible.
  • the outer surface (and the front side and the area of the inside visible from the outside up to the groove) of the cardboard tube can be left as a raw cardboard surface, which creates an obvious impression and is a visible sign of ecology. In addition, it is antistatic and therefore does not get dusty much compared to plastic.
  • the material according to the invention also opens up a simple and varied approach Possibility of designing the cardboard surface by the producer, dealer or end user, in any artistic design, from monochrome to photo motifs, which can be printed or glued on.
  • Another advantage here is that simple, environmentally friendly paints such as watercolors, dispersion, felt-tip pens, wax crayons, colored pencils, ink, etc. can be used, and the final coloring can also be done after the lamp has been produced. This means that, for example, despite the variety, warehousing for the lights can be simplified.
  • the lamp frame can be formed as a section of a wound cardboard or cardboard tube, such as by sawing or cutting off a cardboard tube, a shipping tube, etc., i.e. a tube made of cardboard or cardboard in the shape of a general cylinder with round, oval, square or almost any basic shape, in particular a polygon, preferably a vertical cylinder.
  • a preferred shape which will be discussed further below as an example, is a round, preferably circular, cardboard tube, i.e. in the shape of a vertical circular cylinder, since this shape is widely available and easy to produce - for the lamp pane and lamp frame.
  • the lamp can be produced easily, quickly and without a great deal of energy expenditure and waste or waste, in particular from a wide range of semi-finished products already available on the market and/or with standard machines, without the complex production and operation of injection moulds, stamping and bending molds, as in the prior art etc (carbon footprint).
  • Preferred embodiments of the lamp frame have, for example, an inner diameter of at least 100 mm or 200 mm, at most up to a maximum of 1200 mm, and/or a wall thickness of between 3 mm and 10 mm.

  • the lamp frame height can be between 2 and 15 cm, preferably around 5 to 8 cm.
