Definitions

  • the present invention relates to a luminaire for lighting purposes, e.g. an indoor or outdoor light, which has LEDs as lighting in at least two different colors.
  • Luminaires with LED light sources ( light emitting diodes, which are also organic light emitting diodes to understand) and a transparent cover of an optically structured or diffusely scattering surface element are often constructed so that the light of the LEDs from the back hits the cover and accordingly the optical properties of the cover, the light is emitted to the light exit side.
  • a luminaire for mixing light colors is from DE 10 2012 213 046 A1 known.
  • a light module is provided, which has the LEDs on two different boards. The boards are arranged so that the LEDs of the two different colors are as close as possible to each other to produce the most homogeneous possible light mixing.
  • Object of the present invention is to provide a luminaire with LED light sources in at least two colors available, which ensures the simplest possible way a good mixing of the light colors, with a flat as possible design of the lamp can be realized.
  • a luminaire for lighting purposes with an array of LED light sources which have at least two groups of spectrally different emitting LEDs, the LEDs of each of the groups are each arranged in a regular grid and the at least two grids intermeshing in the light are arranged in a surface, wherein at a distance from said LED surface, a diffuser element, in particular a diffuser plate or a diffuser film is arranged, so that the light of the LEDs incident on the diffuser element, wherein the LEDs each individually a lens body is associated, which the light emitted by the LED expands so that the LEDs in each case in a grid in their entirety irradiate the diffuser element with a homogeneous intensity distribution, and the intensity distributions of the two grids of LEDs are superimposed on the diffuser element.
  • the lens body which are each assigned to the LEDs individually, the light of the LEDs is expanded even before it impinges on the diffuser element.
  • a homogeneous intensity distribution of each group of LEDs are generated, so that mixes the light of the two colors on the diffuser element such that color differences from human eye can no longer be perceived.
  • a homogeneous intensity distribution in this context means an intensity distribution in which the intensities of the relevant light color on the diffuser element do not differ from the mean value by more than ⁇ 10% between the brightest and the lightest weakest regions on the diffuser element, effects only in the edge region of the diffuser element Disregard diffuser element.
  • each LED of the first grid has as its nearest neighbor in the area one or more LEDs of the second grid.
  • the distance between an LED of the first grid to all nearest neighbors in the second grid can be selected to be the same size.
  • the two LED grids are arranged at an angle between 30 ° and 70 °, in particular offset by 45 ° to each other.
  • the LEDs may be the same distance apart, e.g. in an orthogonal grid.
  • the two grids with LEDs of different colors can each be made the same.
  • other configurations may also include hexagonal grids, in which also each one LED of the first color only has LEDs as nearest neighbors, which have the second color.
  • the LEDs of both grids are arranged on a different board.
  • This embodiment has the advantage that the LEDs of each color can be easily contacted via a common board in order to be able to control the LEDs of the two colors separately from one another.
  • Each of the two grids may also include multiple boards.
  • the blanks of the two grids are preferably arranged intermeshing.
  • the boards can mesh comb-shaped.
  • Other configurations provide sawtooth or serpentine lines as sinkers, each interdigitated.
  • LEDs are arranged in one color only, so that in interlocking boards preferably the nearest neighbors of an LED are again formed by LEDs of the other color.
  • the lens bodies each generate a light distribution of the LED in a sectional plane in which the optical axis of the LED is located (also referred to as C-plane in the lighting art), the two symmetrical maxima in an angular range of ⁇ 40 ° to ⁇ 80 ° , preferably between ⁇ 50 ° and ⁇ 70 °, each measured from the optical axis.
  • a light distribution which is also referred to as batwing distribution ensures good mixing of the light of adjacent LEDs, because the light distribution is relatively wide.
  • batwing distribution ensures good mixing of the light of adjacent LEDs, because the light distribution is relatively wide.
  • the light of adjacent LEDs superimposed already within a comparatively short distance to the LED surface, so that a homogeneous mixing of the light has already taken place when the light strikes the diffuser element.
  • the lens bodies each generate a rotationally symmetrical light distribution.
  • the symmetrical maxima which have been described in a sectional plane according to the previously described embodiment, can form a circulating maximum.
  • the lens bodies are designed as free-form lenses which produce a first light distribution in the main planes C0-C180 and C90-C270 and a second light distribution different from the first in the main planes C45-C225 and C135-C315, wherein in particular the second Light distribution is wider than the first light distribution.
  • the main planes C0-C180 and C90-C270 are two C-planes (ie, cut planes containing the optical axis of the LED and arranged perpendicular to the LED surface) which are at an angle of 90 °.
  • the other main planes C45-C225 and C135-C315 are accordingly defined by two cutting planes which are turned at an angle of 45 ° to the aforementioned planes.
  • Cx denotes the C-planes commonly used in lighting technology, where x denotes the azimuthal angle.
  • This embodiment has the advantage that, for example, in an orthogonal grid of LEDs, the light distribution over the diffuser element, which already emanates from each individual LED, is more uniform, because a broader light distribution in the plane takes place diagonally between the LEDs in the two grids, while a narrower light distribution in the direction of the next adjacent LED is done.
  • these free-form lenses can produce a homogeneous intensity distribution across the diffuser element for each light color, even considering that the LEDs are still spaced a relatively large distance apart and the diffuser element is relatively close is arranged to the LEDs.
  • the lens bodies of the first LED grid generate a light distribution in a sectional plane, which in each case contains the optical axis of the LED, with two maxima in symmetrical angular ranges and the lens bodies of the second LED grid each generate in a sectional plane which the optical Axis of the LEDs, a light distribution with two maxima in a symmetrical angle ranges, and the LEDs of both grids are arranged at such a distance, and the diffuser element is opposite the surface of the LEDs is arranged at such a distance that the directional beams of two maxima overlap adjacent LEDs in the cutting planes before the light impinges on the diffuser element.
  • This arrangement ensures that the light of adjacent LEDs of different colors already mixes before the light impinges on the diffuser element. This makes it possible to achieve a very homogeneous light distribution on the diffuser element.
  • the person skilled in the art will understand that the distance of the LEDs from one another, the width of the light distributions, ie the angular range in which the maxima are generated, and the distance between the LED surface and the diffuser element interact with one another in order to achieve homogeneous light mixing , In the case of a broader light distribution, for example, the distance of the LEDs from one another may be greater and the distance between the diffuser element and the LED surface may be smaller. With a further distance of the diffuser element from the LED surface, the distance of the LEDs from one another can be selected to be larger or, if necessary, the light distribution which is generated by the lens bodies can also be selected to be narrower.
  • an optically structured, transparent element is arranged on the side of the diffuser element facing away from the LEDs.
  • a prism plate or a disk provided with lenticular elevations can be arranged opposite the diffuser element.
  • This optically structured, transparent element can produce desired effects by refraction of light, in particular serve to glare the lamp. It should be understood that the mixing of the light already largely takes place in the diffuser element, while the optically structured, transparent element serves to direct the light of the already mixed-in light.
  • the distance between the diffuser element and the optically structured, transparent element can be between 1 ⁇ m and 0.5 ⁇ m, according to one embodiment.
  • the distance between the diffuser element and the optically structured, transparent element which is preferably designed in the form of an air gap, is advantageous for the properties the light control through the optically structured, transparent element to improve. If the optically structured transparent element were connected directly to the diffuser element, u. U. the refraction of light when entering the light in the optically structured, transparent element is not sufficient to achieve the desired light control. In the case of an air gap, it is ensured that, when the light enters the optically structured, transparent element, there is an optical transition from the optically thinner to an optically denser medium with the corresponding refraction of light.
  • the distance between the diffuser element and the optically structured, transparent element can also be increased.
  • an air gap between 15 mm to 30 mm may be provided. This arrangement has the advantage that the light mixing after exiting the diffuser element and before entering the optically structured, transparent element even better.
  • the distance (air gap) between the diffuser element and the optically structured, transparent element is between 0.5 mm and 20 mm.
  • the lamp has an approximately square housing, of which a sectional view FIG. 1 only a section of the bottom side 2 can be seen.
  • a number of LEDs 4 and 6 are mounted on a board (not shown).
  • the LEDs 4 and 6 each form an orthogonal grid, wherein the gratings are arranged at an angle of 45 ° to each other.
  • LEDs 4 and 6 emit light of different spectral color.
  • the luminaire is designed so that the light colors of the LEDs are mixed so well that the observer can not perceive the color difference between the LEDs on a diffuser element from the outside.
  • the diffuser element 8 is arranged, which is formed in the embodiment shown as a lens.
  • the diffuser 8 has frosted surfaces, so that the light passing through the diffuser 8 is evenly distributed.
  • FIG. 1 As in the sectional drawing FIG. 1 can be seen, a lens element 10 is arranged above each LED 4 and 6, respectively.
  • the lens element 10 influences the light distribution of each individual LED.
  • the light distributions of the LEDs are shown schematically by dashed lines. It can be seen that, contrary to the normal beam characteristic of an LED, namely as a Lambert radiator, the light distribution in the illustrated section is wider and has two symmetrical maxima.
  • the light distribution of an LED is shown in the C0-C180 plane of the luminaire.
  • the light distribution has two symmetrical maxima at ⁇ 63 °.
  • the lens body 10 are rotationally symmetrical.
  • the line on which the maxima of the light distribution are approximately at the level of the diffuser element, are in the FIG. 2 shown as dashed circles.
  • a homogeneous intensity distribution is to be understood as a distribution whose intensity maxima and intensity minima do not fluctuate more than ⁇ 10%. Due to the wide expansion of the light distribution of each individual LED, the mixing of the light within the distance h can be achieved. Compared to a lamp without lens body, which contains no expansion of the light distribution, therefore, the diffuser element 8 can be mounted at a much closer distance h to the lights. Without the lens elements 10, the diffuser element would have to be attached to the LEDs at a much greater distance h to produce a homogeneous intensity distribution because the emitted light would require a longer distance for mixing.
  • the LEDs in the plane 2 are each arranged in an orthogonal grid, wherein the two gratings are in one another.
  • the distance to the next neighbor along the orthogonal main axes a and b are the same size.
  • the grids are therefore offset by 45 ° to each other. This corresponds to a preferred embodiment.
  • hexagonal structures for example, may also be used. Even with these grids, it is possible that the next neighbor of each LED forms a spectrally different emitting LED, while the neighbor next neighbor again forms a spectrally gleichabstrahlende LED.
  • the lens elements generate a rotationally symmetric light distribution about the optical axis of the LED.
  • a deviating light distribution can be generated.
  • the orthogonal grating of this embodiment for example, a light distribution which is wider in the axes diagonal to the main axes of the orthogonal grating than that parallel to the main axes of the orthogonal grating is preferable.
  • the dashed circles are approximately one square.
  • the homogeneity of the intensity distribution on the diffuser element can be further improved for a given grating spacing a or b and for a given distance h.
  • the lens bodies of this embodiment produce a broader light distribution in the main planes C45-C225 and C135-C315 than in the main planes C0-C180 and C90-C270.
  • FIG. 4 For the realization of the two telescoped orthogonal gratings of LEDs of different colors, a circuit arrangement as in FIG. 4 shown selected according to an embodiment of the invention.
  • a plurality of LEDs of the same color are arranged comb-shaped in a circuit and pushed together with a same arrangement of LEDs of the other spectral color.
  • the LEDs 4 and 6 may each be arranged on a separate board, which mesh with each other like a comb.
  • This type of electrical contacting has the advantage that the LEDs of the two colors can be controlled differently from each other. By different dimming of the two LED grid can therefore produce different mixed colors with the lamp. Since each group of LEDs already produces an approximately homogeneous light distribution on the diffuser element 8, each mixed color is distributed homogeneously on the diffuser element, so that the viewer always perceives a lamp in a uniform color.
  • each board strip comprises only one group of LEDs each having the same spectral light emission.
  • FIG. 7 which represents a further embodiment of the invention, corresponds to the illustration in FIG. 1 ,
  • an optically structured, transparent element 12 is provided on the side of the diffuser element 8 facing away from the LEDs.
  • the optically structured, transparent element 12 has a prism structure on the light exit side, which in the FIG. 7 in the sectional drawing in the direction perpendicular to the longitudinal extent of the prisms can be seen. These prisms ensure refraction of the light due to refraction of light, because the diffusely emitted light of the diffuser element is deflected by refraction of light to the prisms. Preference is given to a light emission with a shield above a critical angle, for example between 50 ° and 70 ° with respect to the surface normal of the light exit surface.
  • the optically structured, transparent element according to another embodiment may also have lenticular elevations instead of prisms.
  • cones or prisms or truncated cones or prisms are also possible, e.g. to create a shield in two orthogonal directions.
  • the optically structured, transparent element 12 of FIG. 7 is arranged at a distance c from the diffuser element 8. This distance, which is formed in the form of an air gap, is preferred so that the light which enters the optically structured, transparent element already undergoes a refraction of light from an optically thinner to an optically denser medium. If the optically structured, transparent element 12 were mounted directly adjacent to the diffuser element 8, the effectiveness of this element 12 would be reduced because the refraction of light at the interface between air and the material of the transparent element 12 is eliminated.
  • FIG. 8 shows a further variant of the embodiment according to FIG. 7
  • the distance d between the diffuser element 8 and the optically structured, transparent element 12 is increased.
  • This embodiment has the advantage that in the region between the diffuser element 8 and the optically structured, transparent element 12 remains a greater distance in which a further light mixing can take place.
  • a distance-optimized arrangement between the diffuser element 8 and the optically structured, transparent element 12, an air gap between 0.5 mm to 20 mm is formed.
  • the invention is not limited to orthogonal gratings, but other regular grating types may be provided (especially hexagonal).
  • the invention is not limited to two groups of different spectrally radiating LEDs. According to an alternative embodiment, three or more groups of different spectrally emitting LEDs may also be used.
