Abstract

The invention relates to a grid lamp (1, 11) with a plurality of reflector lamps (2, 3, 12, 3) arranged in a grid, each of the reflector lamps (2, 3, 12, 3) comprising a semiconductor lamp (4a-d, 5a-e ) and a reflector shell (6) which can be irradiated by the semiconductor radiator (4a-d, 5a-e) and wherein the semiconductor radiator (4a-d, 5a-b, 5d-e) is eccentric with respect to the reflector shell of at least one reflector radiator (6) is arranged.

Description

  • The invention relates to a grid lamp with a plurality of arranged in a grid reflector radiators, each of the reflector emitter having a semiconductor emitter and a reflector dish which can be irradiated by the semiconductor emitter. The grid light can be used, for example, as a ceiling light or ceiling washer.
  • There are grid lights known as ceiling lights, in which a grid-like reflector structure of fluorescent tubes is backlit. Furthermore, louvre luminaires with light-emitting diodes (LEDs) are known as light sources, the LEDs each being assigned a reflector shell in order to carry out beam shaping. In these reflector radiators, the LEDs are arranged centrally to the reflector shells, and an adjustment of a Lichtabstrahlmusters the grid light can be achieved via a variation of the configurations and / or orientations of the reflector shells.
  • It is the object of the present invention to provide a grid lamp with a light in many ways versatile adjustable Lichtabstrahlmuster.
  • This object is achieved according to the features of the independent claims. Preferred embodiments are in particular the dependent claims.
  • The object is achieved by a grid lamp with a plurality of arranged in a grid reflector lamps, each of the reflector emitter having a semiconductor emitter and an irradiable by the semiconductor reflector reflector dish and wherein the semiconductor emitter of at least one reflector emitter is arranged eccentrically with respect to the reflector dish.
  • This louvre luminaire has the advantage that its light emission pattern can be varied by simple means compared to centrally arranged semiconductor radiators, e.g. with respect to an opening angle and / or an intensity distribution. In particular, can be dispensed with a redesign and / or changed orientation of the reflector shells, which simplifies production.
  • In particular, a semiconductor emitter may be a light-generating unit having at least one (i.e., one or more) semiconductor light source for generating light. The light may include visible light, infrared light and / or ultraviolet light. The at least one semiconductor light source may comprise optics, e.g. a diffuser and / or a lens etc.
  • Preferably, the at least one semiconductor light source comprises at least one light-emitting diode. If several LEDs are present, they can be lit in the same color or in different colors. A color may be monochrome (e.g., red, green, blue, etc.) or multichrome (e.g., white). The light emitted by the at least one light-emitting diode can also be an infrared light (IR LED) or an ultraviolet light (UV LED). Several light emitting diodes can produce a mixed light; e.g. a white mixed light. The at least one light-emitting diode may contain at least one wavelength-converting phosphor (conversion LED). The phosphor may alternatively or additionally be arranged remotely from the light-emitting diode ("remote phosphor"). The at least one light-emitting diode can be in the form of at least one individually housed light-emitting diode or in the form of at least one LED chip. Several LED chips can be mounted on a common substrate ("submount"). The at least one light emitting diode may be equipped with at least one own and / or common optics for beam guidance, e.g. at least one Fresnel lens, collimator, and so on. Instead of or in addition to inorganic light emitting diodes, e.g. based on InGaN or AlInGaP, organic LEDs (OLEDs, for example polymer OLEDs) can generally also be used. Alternatively, the at least one semiconductor light source may be e.g. have at least one diode laser.
  • The reflector shell may in particular have at least one reflection surface which reflects light incident from the semiconductor radiator. The reflected light subsequently emerges through a light exit surface. In most cases, the light of the semiconductor emitter can also emerge from the light exit surface without reflection at the reflection surface.
  • The reflection surface typically tapers from the light exit surface in the direction of the semiconductor radiator. The reflection surface may have in the profile, for example, a spherical, a parabolic, a hyperbolic or a free-form, etc. shape. A peripheral contour of the reflection surface in the area of the light exit surface may be e.g. be rectangular and / or curved, for example, square or circular. The reflection surface may also change the shape of its peripheral contour from the light exit surface toward the semiconductor radiator, e.g. from an at least substantially rectangular shape on the light exit surface to a round or oval shape on the other side, e.g. at a base opening (see below).
  • The reflector shell can also have in particular a base opening, through which light of the semiconductor radiator is incident on the reflector shell or through which the semiconductor emitter is inserted into the reflector dish. The base opening may, in particular, be located at a lower area of the reflector shell (while the light exit area represents an upper area).
  • The fact that the semiconductor emitter is arranged eccentrically with respect to the reflector dish may in particular mean that the semiconductor emitter is arranged eccentrically with respect to the reflection surface of the reflector dish. An eccentric arrangement may in particular be an arrangement in which the semiconductor radiator is offset laterally to an axis of symmetry of the reflection surface. An eccentric arrangement may also be an arrangement in which the semiconductor emitter is laterally offset from an optical axis of the reflection surface. In particular, an optical axis of the semiconductor emitter may then be laterally offset with respect to the optical axis of the reflection surface.
  • In the event that the semiconductor emitter has a plurality of semiconductor light sources, in particular a center of gravity of the semiconductor light sources can be arranged off-center.
  • The reflector shells or at least their reflection surfaces can in particular be of a similar design, which simplifies manufacture.
  • It is an embodiment that the reflector dish has a base opening and the semiconductor emitter is arranged eccentrically with respect to the base opening of the reflector dish. This allows a particularly simple installation.
  • It is still an embodiment that the semiconductor radiators are arranged eccentrically differently from at least two reflector radiators. Under a diverse eccentric arrangement, in particular an arrangement can be understood, in which the semiconductor emitters of at least two reflector emitters have a different distance or offset and / or are arranged eccentrically in a different direction or offset. This embodiment enables a particularly diverse adjustment of the Lichtabstrahlmusters.
  • It is yet another embodiment that the semiconductor emitter of at least one reflector emitter is arranged centrally with respect to the reflector dish. It can therefore be used together eccentrically arranged and centrally arranged semiconductor emitters. This embodiment allows an even more varied adjustment of the Lichtabstrahlmusters.
  • It is a further embodiment that the grid is a matrix-shaped grid. The matrix-shaped grid can have, for example, m rows and n columns of reflector shells (m × n grid).
  • It is also an embodiment that the semiconductor radiators of at least one or a few reflector radiators are offset in a direction of a next edge of the raster (for example a raster of an associated subgroup, as described in more detail below) and / or the raster lamp. In particular, semiconductor emitters (only) arranged near the reflector reflector can be offset in a direction of the next edge of the grid. Thereby, a beam cone of this reflector radiator with respect to the grid lamp can be directed more inward than outward, and consequently a Lichtabstrahlmuster the grid lamp with a comparatively small opening angle and a high luminance can be generated. A reflector emitter arranged at the edge can also be a reflector emitter arranged at the edge with respect to a subgroup (as explained below).
  • It is also an embodiment that the semiconductor radiators of at least one or a few reflector radiators are offset against a direction of a next edge of the raster (for example a raster of an associated subgroup, as described in more detail below) and / or the raster lamp. In particular, semiconductor radiators arranged close to the reflector reflector can be offset against a direction of the next edge of the grid. Thereby, a beam cone of this reflector radiator with respect to the grid lamp can be directed more outward than inward, and consequently a Lichtabstrahlmuster the grid lamp can be generated with a relatively large aperture angle and a lower luminance.
  • It is also an embodiment that the reflector radiators can be divided into subgroups with jointly activatable semiconductor radiators and the semiconductor radiators of different subgroups of reflector radiators have different emission characteristics. As a result, different light emission patterns can be generated with a grid light optionally.
  • It is a further development that at least one reflector emitter belongs to only one subgroup. It is still a development that at least one reflector emitter belongs to several subgroups. A reflector element belonging to several subgroups may have only one semiconductor emitter or may have different semiconductor emitters which can be activated for different subgroups.
  • In particular, each of the subgroups can each be configured as described above. For example, in one subgroup, the semiconductor emitters of reflector emitters arranged peripherally with respect to this subgroup may be offset in one direction of a next edge of the (sub) grid of this subgroup and in another subgroup contrary to a direction of a next edge of the (sub) grid be offset to another subgroup. Also, the semiconductor emitters of different subgroups may, for example, emit light of different color to meet different color requirements of a user. The subgroups can therefore differ, for example, in the emission characteristic of the semiconductor emitters and / or in the type of off-center arrangement.
  • It is still an embodiment that a subgroup of reflector emitters has warm white light radiating semiconductor emitter and another subset of reflector emitters has cold white light emitting semiconductor emitters. In particular, the subgroups or their semiconductor radiators can be activated independently of one another, e.g. such that only cold-white light-emitting reflector radiators, only warm-white light-emitting reflector radiators or both types of white-light radiating reflector radiators are activated together.
  • It is also an embodiment of a grid lamp with a matrix-shaped grid, that the sub-groups of reflector lamps are arranged in strips. Under a strip-shaped arrangement can be understood in particular an arrangement in which a subset of one or more strips (entire columns or rows) is constructed of reflector emitters.
  • It is still an embodiment that strips of reflector emitters of a common subgroup are formed identically.
  • It is also an embodiment that a number of reflector radiators different subgroups of reflector emitters may be different. This allows a Lichtabstrahlmuster be set even more flexible. For example, a raster luminaire configured in a (m × n) raster may have a first subset of (m '× n') reflector radiators arranged in matrix form and a second subgroup of (m "× n") reflector radiators, wherein, purely by way of example, m '= m' ', but n'> n '' and furthermore m = m '= m' 'and n = n' + n ''.
  • It is a preferred application that the grid light is a ceiling light and / or a ceiling washer or represents a part thereof.
  • The above-described characteristics, features, and advantages of this invention, as well as the manner in which they will be achieved, will become clearer and more clearly understood in connection with the following schematic description of exemplary embodiments which will be described in detail in conjunction with the drawings. In this case, the same or equivalent elements may be provided with the same reference numerals for clarity.
  • 1 shows in plan view a grid lamp according to a first embodiment with a matrix-shaped arrangement of reflector radiators;
  • 2 shows the grid lamp according to the first embodiment as a sectional view in side view a;
  • 3 shows a sectional view in side view of a grid lamp according to a second embodiment with a matrix-shaped arrangement of reflector radiators.
  • 1 shows in plan view a grid lamp 1 in the form of a ceiling light with a matrix-like arrangement of m = 12 columns and n = 9 rows of reflector radiators 2 . 3 , 2 shows the grid lamp 1 as a sectional view in side view.
  • Each of the reflector emitters 2 has a semiconductor emitter in the form of a first LED 4a . 4b . 4c respectively. 4d on, and each of the reflector emitters 3 has a semiconductor emitter in the form of a second LED 5a . 5b . 5c . 5d respectively. 5e , Each of the reflector emitters 2 . 3 has one by means of the associated LED 4a -D or 5a -E irradiable, similarly constructed reflector shell 6 on. The reflector shell 6 Here, purely by way of example for the simple description of the invention, has a box-shaped basic shape with a frontal light exit surface 7 and a rear base opening 8th on. An inside of the lateral surface provides a reflection surface 9 represents.
  • The LEDs 4a -D are all eccentric with respect to the respective reflector shell 6 arranged, that is, a lateral offset with respect to an axis of symmetry L of the reflection surface 9 the reflector shell 6 which simultaneously corresponds to the optical axis. These are the LEDs 4a -D here at the edge of the base opening 8th , and therefore arranged off-center. More precisely, the LEDs are 4a and 4b on the one hand and the LEDs 4c and 4d on the other hand, arranged differently off-center so as to be offset in different directions. And that's the LEDs 4a and 4b shifted to the left towards their nearest edge Rl1, while the LEDs 4c and 4d are offset to the right in the direction of their next right edge Rr1. Under the edge Rl1 and Rr1 here becomes an edge of the reflector emitters 2 Understood. The edges of the reflector emitters 3 are arranged further out and drawn in as left edge Rl2 and as right edge Rr2. The left edge Rl2 and the right edge Rr2 here correspond to the edge of the grid of both reflector emitters 2 and 3 or the grid lamp 1 ,
  • The LEDs 5a . 5b . 5d and 5e are also off-center with respect to their associated reflector shell 6 arranged, and analogous to the LEDs 4a -D so that the LEDs 5a . 5b . 5d and 5e are shifted in the direction of their nearest edge Rl2 or Rr2. The middle LED 5c , which has an equal distance to both edges Rl2, Rr2, however, is centered with respect to their reflector shell 6 arranged.
  • The LEDs 4a -D and the LEDs 5a -E differ here purely by way of example essentially only in their color, the LEDs 4a -D warm white lights and the LEDs 5a -E shine cold-white. The LEDs 4a -D and the LEDs 5a -E are independently activatable in groups, in particular individually or together. The reflector emitters 2 and 3 Consequently, they can functionally be divided into subgroups with mutually activatable LEDs 4a -D or LEDs 5a -E be split. The subgroup of reflector lamps 2 consists of (m = 12 × n = 4) = 48 reflector emitters 2 corresponding to columns n = 2, 4, 6 and 8. The subgroup of reflector lamps 3 consists of (m = 12 × n = 5) = 60 reflector emitters 3 corresponding to columns n = 1, 3, 5, 7 and 9. The number of reflector emitters 3 is therefore greater than the number of reflector emitters 2 , The subgroups can therefore be activated independently of each other and can thus be viewed independently of each other
  • When operating the subgroup of reflector lamps 2 generate these, as shown by the dashed lines contours K of the individual reflector emitters 2 indicated, due to the edge-oriented offset of the LEDs 4a -D a light cone of the louvre lamp 1 which has a comparatively small opening and a high brightness in the middle. Thus, image positions B1 and B2 are slightly outside and opposite to an edge Rl1 or Rr1 of this subgroup substantially only by an LED 4a respectively. 4d illuminated while the center M through all four LEDs 4a to 4d is illuminated.
  • A likewise rather narrow light cone of the louvre lamp 1 is also in an operation of the subgroup of the reflector radiator 3 generated, and therefore also in a joint operation of both types of reflector emitters 2 and 3 ,
  • 3 shows a sectional view in side view of a grid lamp 11 according to a second embodiment with a matrix-shaped arrangement of reflector radiators 12 and 3 , The grid lamp 11 is similar to the grid lamp 1 constructed and uses reflector spotlights 12 instead of the reflector emitter 2 , The reflector emitters 12 differ from the reflector emitters 2 in that the inner two LEDs 4b and 4c are offset against the direction of their next edge Rl1 or Rr1 this subgroup and the two outer LEDs 4a and 4d are arranged centrally. As a result, a wider beam of light this subgroup of the grid lamp 11 achieved, which reaches a relatively uniform brightness distribution. Thus, the image positions B1, B2 and M here each of two LEDs 4a . 4b ; 4b . 4c respectively. 4c . 4d illuminated.
  • Although the invention has been further illustrated and described in detail by the illustrated embodiments, the invention is not so limited and other variations can be derived therefrom by those skilled in the art without departing from the scope of the invention.
  • Thus, the reflector shells of the reflector radiators can generally also be designed differently, e.g. depending on the offset and / or the color or brightness of the associated semiconductor emitter.
  • Also, alternatively, e.g. some or all of the reflectors belong to both sub-groups and like to e.g. have both warm white and cold white LEDs, possibly with a different offset.
  • Also, the reflector radiators of the subgroups may not be arranged in a matrix-like raster, but e.g. cruciform, etc.
