Definitions

  • Reflector element for an electric lamp and lamp with such a reflector element
  • the invention relates to a reflector element for an electric lamp and an electric lamp with such a reflector element.
  • socket GX53 In known from the prior art flat lamps, a specially developed for these applications socket GX53 is used. Furthermore, lamps with light-emitting diodes as light sources have established themselves on the market, in which a light-emitting diode (LED) module is formed as part of the light. This is connected without the use of a socket-socket system to the electronic driver of the light-emitting diodes and connected in order to dissipate the heat generated in the light-emitting diode chip heat-conducting with the lamp body, which then serves as a heat sink.
  • LED light-emitting diode
  • lamps with a socket-type socket system require a lamp holder and different codings of the socket-socket system are required in order to prevent the insertion of unsuitable lamps into the socket.
  • the lamps are designed to be larger and a complex installation with regard to the lines, their wiring and the attachment of the lamp and the lamp with the socket are required.
  • symmetrical configurations of a luminaire are not feasible. Last but not least is an increased cost of materials required and only a limited light output guaranteed.
  • a flat lamp is understood to mean one which is designed with a flat geometry.
  • the flat lamp is to be understood in that the height of the light source is smaller, in particular substantially smaller than the width and the depth of the light source.
  • flat lamp lamps in which one or more light sources are arranged in a plane, but also those in which a discharge lamp is used and the discharge vessel extends in a plane or, for example, is also slightly conical. Even with a conical shape, however, the dimensions are such that the height of the cone is smaller, in particular much smaller than the radial dimensions.
  • flat lamps may be formed substantially disc-shaped.
  • An inventive reflector element for an electric lamp is constructed so that it is formed at least for photocatalysis and / or color conversion of incident light, in particular emitted by the electric lamp light.
  • a reflector element can be created, which has multi-functionality, whereby the operation of an electric lamp and in particular the lighting properties can be significantly improved.
  • this also allows a flat construction concept to be maintained.
  • the reflector element can be constructed such that it is designed for light scattering and light reflection and for photocatalysis and color conversion of the light.
  • a specifically constructed and / or coated element By a specifically constructed and / or coated element, a multi-functionality can be achieved.
  • a particularly flexible adaptation of the element to the respective lamp or luminaire is thereby possible, so that a very situation-adapted concept formation is achieved with regard to the use of the lamp or the luminaire.
  • a reflector element is understood to mean a component which at least partially reflects light, this meaning both directional reflection according to the optical law with angle of incidence equals the angle of reflection of the light and scattering.
  • the reflector comprises a plate-like carrier, which is made of a transparent material, in particular of plastic or glass, and is coated with an at least partially reflecting layer.
  • the layer may be formed on the side of the carrier facing the light source during operation and / or on the side facing away from the light source.
  • the carrier is formed from at least two different plastics, which have different refractive indices.
  • a particularly suitable embodiment for light generation can be made possible, which, moreover, is also designed to minimize weight.
  • a first plastic PC polycarbonate
  • a second plastic PMMA it is provided that a first plastic PC (polycarbonate) and a second plastic PMMA.
  • the carrier is at least partially made of light formed by transmitting material, so that the interpretation of the light-directing element is given as a partially mirrored reflector with a reflection factor R.
  • the reflector element is preferably coated with TiO 2 .
  • TiO 2 may also be incorporated as material in the at least partially reflecting layer.
  • Such a coating is preferably applied in regions, in particular in edge regions of the reflector element.
  • the reflector element for color conversion of light having a first color temperature is formed in light having a first lower second color temperature and the partially reflecting layer is a wavelength-selective coating, so that the reflector element is formed as a dielectric mirror or as an interference filter. There is then no color conversion layer formed.
  • the reflector element for color conversion of light having a first color temperature is formed in light having a first lower second color temperature and the partially reflecting layer is a color conversion layer.
  • reflected light can have a different color than transmitted light, which opens up new design possibilities and, in particular, enables a better adaptation of the light to illumination scenarios. So, for example often perceived as more pleasing to people of lower color temperature in one direction, while light of a higher color temperature, which is often perceived as cold, is increasingly being delivered in a different direction. Thus, for example, an adequate supply of circadian effective light on the one hand and a pleasant perceived illumination of certain areas on the other hand can be provided. One way to do this would be to illuminate walls or ceiling with light of high color temperature, for example, daylight-like spectrum, while a residence area is illuminated with light lower color temperature by appropriate attachment and interpretation of the reflector element.
  • scattering bodies are formed in the reflector for light scattering, which bodies are at least partially formed as scattering bodies of a phosphor material, in particular of the YAG: Ce type.
  • a phosphor material in particular of the YAG: Ce type.
  • corresponding phosphors are possible in which the element yttrium is partially or completely replaced by one of the rare earth metals.
  • the at least partially reflecting layer is applied to the side of the reflector which faces the lamp during operation. This allows direct reflection to be achieved. However, it can also be provided that this coating is applied to the side facing away from the lamp of the reflector. In such an embodiment, a reflection is made possible only after transmission of the carrier of the reflector layer.
  • the plastic material of the carrier has in particular a corresponding transmittance T.
  • the reflector can thus be adapted to the situation and depending on the size of the reflection factor R and the transmittance T of components or material components of the reflector, light is either almost completely reflected or almost completely transmitted. It can thus be achieved in this regard, a degeneration of the reflector to the cover.
  • the reflector or the cover can also be designed so that they can be used as Konvetechnischsbegrenzer and virtually switch off the convection.
  • corresponding heat-sensitive lamps which are constructed for example on the basis of low-pressure discharge lamps, can also be used in very cold environments, such as in cold stores.
  • the photocatalytic reaction is enabled without the generation of negative ions.
  • the reflector is placed on top of the lamp and the TiO 2 layer is deposited on the inside of the reflector, the air always comes into contact with the TiO 2 coated reflector because of convection. resulting in a high air flow and thus an efficient air purification.
  • the material to which the reflective layer is applied has a light-scattering design and has a scattering power S. If the reflectance is 0 and the transmittance is almost 100% and the scattering power is 1, the reflector degenerates to the diffuser. The scattering power can be used to adjust the glare and these are reduced accordingly.
  • the scattering bodies consist at least partially of a phosphor, in which respect preferably a phosphor is provided which converts blue light, for example mercury lines and parts of the BAM spectrum into longer-wave light, for example in the green-red spectral region with a temperature shift relative to that of the light source ,

  • the side is aligned with a thicker phosphor layer in the direction where less light is to be emitted through the lamp or on the side on which the reflector is to be mounted.
  • the discharge vessel on the side facing the reflector has a thicker phosphor layer than on the side facing away from the same.
