Definitions

  • the invention relates to a light module, which provides a directed light output, a light system with the light modules and a lamp with light module or light system.
  • Luminaire arrangements or lighting systems are known from the prior art, which use a sheet-like lighting technology with mostly horizontally extending, large light exit surface and which are mounted high on a column and protrude from this or protrude. This serves to illuminate the working area (eg a table) as homogeneously as possible and at the same time to dazzle the user as little as possible.
  • the standard DIN EN 12.464-1 is particularly relevant for this. Solutions known from the prior art in particular use different light-conducting or -breaking or scattering plastic plates (eg microprism plates, micro-pyramidal optics, light guide plates with structures lasered on one side, lateral coupling in order to be able to construct a flatter design, diffuser plates).
  • the invention relates to a light module having a light source, a light-guiding element for substantially parallel light direction of the light emitted by the illuminant, and an anti-dazzle tube extending substantially parallel in the light emission direction of the light directing element away from the light directing element, through which the directed light is emitted to the outside.
  • the term "substantially parallel” is understood to mean that the directional light is aligned parallel with respect to the main emission direction or the inner wall or outer envelope (possibly also the longitudinal axis / symmetry axis) of the anti-dazzle tube.
  • the light module according to the invention effectively prevents the light of the illuminant from scattering widely (for example, spherically), thereby dazzling a user. Rather, the light module according to the invention causes the light to be directed and preferably exits the light module almost in parallel, so that a glare effect on a user only occurs when it is looking in the axial direction (main emission direction or light emission direction) of the light emitted to the outside of the light module.
  • a less slender, more efficient, and smaller standard-compliant lighting arrangement is provided. This benefits both a more modern design of the light module / luminaire assembly and the costs associated with the light module / luminaire assembly (especially manufacturing and assembly costs).
  • the light module can be designed to be particularly compact and space-saving, whereby a total of smaller (floor) lights can be constructed.
  • the anti-dazzle tube has a light coupling opening on a side facing the light guide element, into which the light directed by the light guide element is coupled into the anti-dazzle tube (ie enters it), and a light discharge opening on a side remote from the light guide element, via which the directed light from the Light module or the lighting arrangement is issued, on.
  • the anti-dazzle tube is thus preferably (circumferentially around the longitudinal axis) circumferentially closed and is seen at its two ends in the longitudinal direction open or has at these ends in each case a corresponding opening.
  • the defibrillation tube thus preferably has a tubular shape.
  • Light coupled into the anti-dazzle tube via the light coupling-in opening can thus be emitted in a targeted manner from the light-emitting opening, so that the light output of the light module can be targeted, for example, at an object to be irradiated.
  • the tube shape is highly effective glare allows, since it is simple in design and in practice (eg. Because of dust, tolerances) can reliably suppress a light emission of non-collimated light components simultaneously.
  • the anti-dazzle tube may have a round (e.g., hollow cylinder) or polygonal, preferably hexagonal or rectangular, cross-section.
  • anti-dazzle tube This provides a deflagration tube which allows a high degree of design freedom.
  • a corresponding anti-dazzle tube is particularly advantageous for its production and its mounting in the light module or the luminaire arrangement by their structural shape caused by the cross-section.
  • anti-dazzle tubes can be created, which can be provided with each other and preferably peripherally without any gaps.
  • the anti-dazzle tube is non-reflective and / or light-absorbing at least on its inner side.
  • the non-reflective property of the inside of the anti-glare tube can prevent the light coupled into the anti-glare tube from being reflected substantially non-parallel (for example to the anti-dazzle tube outer sheath) and striking the inside of the anti-dazzle tube, and subsequently reflected in one axis direction emitted outside the light emitted deviating direction and thus can dazzle a user.
  • the light absorption of the inside that is, the energy of the light striking the inside substantially non-collimated light is converted into heat by heating the inside of the anti-glare tube
  • Light module is discharged to the outside. In any case, the effect of the glare of the light module or the light assembly is thereby increased.
  • the side walls of the anti-dazzle tube may extend substantially parallel to the longitudinal axis of the anti-dazzle tube or the light emission direction (axial direction of the light).
  • the longitudinal axis of the anti-dazzle tube is preferably coaxial with the main emission direction or with the light emission direction or axial direction of the light emitted by the light-directing element.
  • the anti-glare tube widens substantially constantly away from the light guide element, the side walls of the anti-glare tube having an angle with the longitudinal axis of the anti-dazzle tube or the light emission direction at an angle relative to the distance of the surface to be illuminated (preferably at the same angle as the flared light bundle). ;
  • a surface to be illuminated is arranged very close to the anti-dazzle tube in order to create a coherent total light area when using multiple anti-dazzle tubes, as will also be described below. The closer the surface of the anti-dazzle tube to be illuminated is, the more preferably the beam can be dispensed in an expanded manner.
  • the ratio of the mean diameter of the anti-dazzle tube to its length is preferably at least 1: 2, particularly preferably at least 1: 5.
  • average diameter is understood to mean that diameter which, viewed in the radial direction, results in averaged around the longitudinal axis of the anti-dazzle tube and over the length of the anti-dazzle tube.
  • a particularly good glare of the light module or the luminaire arrangement has been found in practice. Basically, the glare reduction is better, the longer the anti-dazzle tube, whereby this effect is improved only slightly from a ratio of 1: 5 with further increasing length.
  • the light-directing element may be a reflector, such as a parabolic reflector, and / or a lens optic.
  • a reflector means On the side of the luminous means facing the anti-dazzle tube, a reflector means can be provided, which is designed and arranged in such a way to control the light components of the light emitted by the illuminant (without the presence of the light source) Reflector means) not directly on the reflector (would) meet, to redirect so that this proportion of light is directed to the reflector for the directed light output.
  • the lighting means may be an LED, in particular a high-power LED, wherein the LED has a single LED or an LED cluster.
  • the LEDs used preferably have a size or a typical diameter of about 2 to 40 mm.
  • the anti-dazzle tube has a minimum diameter which corresponds at least to the size or the diameter of the luminous means or of the luminous means module.
  • the diameter of the anti-dazzle tube is not or not substantially greater than the light source itself.
  • “Not or not essential” means that the diameter of the anti-dazzle tube preferably has at least one diameter at which the light module according to the invention can be operated according to the function, but particularly preferably in diameter is not greater than the required for (desired) operation minimum diameter.
  • These bulbs are particularly suitable for the light module or the light assembly, since they are both inexpensive and efficient, especially in terms of cost and lumens per watt.
  • the light-guiding element is formed integrally with the luminous means as a luminous element, in particular as an LED module.
  • the integral and in particular modular design causes a reduction of the assembly cost of the light module or the lamp assembly, which in turn benefits the cost.
  • the invention relates to a lighting system (also referred to herein as a light assembly), comprising at least two light modules according to the preceding embodiments.
  • the advantages described above with regard to the individual light module are transferred to a corresponding system with which In a simple way, a large area with maximum glare emission or can be illuminated.
  • a system consisting of a plurality of small “point light sources” is provided, which by the sum of the "point light sources” is suitable for illuminating a surface.
  • the individual light modules are, for example, independently controllable (for example, dimmable or operable).
  • At least two, several or all of the light modules are preferably arranged in the lighting system in such a way that the directional light of these lighting arrangements is emitted essentially parallel to one another or emerges at an angle in dependence on the distance of the surface to be illuminated, ie it is emitted slightly divergently.
  • the corresponding axial directions or light emission directions or main emission directions are preferably aligned parallel to one another.
  • the light modules can be arranged such that the directed light is imaged on an object to be irradiated as a homogeneous contiguous total light area.
  • the depicted homogeneously coherent total light area on the object to be irradiated results in particular in a visually appealing - da evenly illuminated and large-area illumination of the object to be irradiated with maximum glare reduction.
  • the light modules are arranged such that the directed light of each of the light modules is imaged on an object to be irradiated as a single light surface, wherein the individual light surfaces are imaged directly adjacent to each other, so that the individual light surfaces do not substantially overlap.
  • the term "substantially non-overlapping” is understood to mean that the light surfaces preferably lie directly adjacent to one another, so that no dark zones are formed, with illumination that forms "just no dark zones any longer" (due to the geometric shape of the light spots). resulting overlaps can form a corresponding overlap.
  • the light surfaces and / or the total light surface may have the shape of a polygonal, in particular a quadrangle or hexagon, and / or circle.
  • the light areas and / or the total light area of the cross-sectional shape may correspond to the respective anti-dazzle tube.
  • the already existing structure of the anti-dazzle tube can thus be used to form the light surfaces and / or correspondingly coherent total light area.
