Definitions

  • the present invention relates to an LED module for emitting mixed light, preferably white light, and a method for producing such an LED module.
  • the present invention relates to an LED module that is suitable for lights with small reflector sizes.
  • the present invention finally relates to a lighting device with built-in LED module.
  • LED modules which are suitable for emitting white light, see, for example WO 2013/015058 A1 . WO 2012/165007 A1 . US 2011/0278605 A1 and US 2011/0116252 A1 , These LED modules usually have a light-emitting light field, which is formed by a combination of individual light points. The individual points of light are designed to emit different light spectra. For example, blue light, red light and yellow light generated by a phosphor are emitted from the light spots.
  • Such a known LED module 10 is for example in the Fig. 1a shown.
  • Fig. 1b shows a top view of the same LED module 10.
  • the LED module 10 has a light field 12, which is arranged together with other components 18 on a module plate 17.
  • the light field 12 is formed from a plurality of light spots 13a, 13b, 13c, each of which emits light from another wavelength range, ie a different light spectrum.
  • Each of the light spots 13a, 13b, 13c is, as in FIG Fig. 1b shown assigned at least one LED 16.
  • the light spots 13a, 13b, 13c are generally formed by so-called glob tops (drops of disperse) above the LEDs 16.
  • the known LED module 10 has the disadvantage that it has too large a light field 12 in order to implement lamps with small reflector sizes.
  • the Glob Top method it is not possible to further reduce the diameter of the light field 12.
  • the object of the present invention is to provide an LED module for emitting mixed light, preferably white light, which improves the known state of the art.
  • the present invention relates to an LED module for emitting mixed light, preferably white light, which has a light field which is subdivided into a plurality of regions for emitting different light spectra, wherein the regions of the light field are areal sectors.
  • the light field is a light emitting surface of the LED module according to the invention. Due to the planar sector distribution of the light field, it is possible to significantly reduce the total area of the light field in comparison with the total area of a known LED module containing points of light defined by glob tops. Due to the sector arrangement, the total light emission surface of the light field can in particular be reduced by at least 16%. Such a reduction is not possible with the glob top approach known from the prior art. Due to the significant reduction in area of the light field, the LED module according to the invention is also suitable for lights with small reflector sizes.
  • At least two area sectors are provided for each light spectrum.
  • the LED module according to the invention is designed, for example, to emit three different light spectra. In each case a light spectrum is coupled out of at least two of the area sectors of the light field. As a result, a very homogeneous and color-true mixed light, in particular white light, can be generated by the LED module as a whole.
  • the outer contour of the light field is round. According to the invention, the outer contour of the light field is circular. The circular shape is particularly advantageous for lights that have optics with attached reflector.

  • circular islands may be provided in the light field for outputting at least one other spectrum of light, which are advantageously designed to emit light from the red light spectrum.
  • Both the circular sectors and the circular islands in the light field are area sectors.
  • This advantageous arrangement of the area sectors in the light field for example, an LED module can be formed which emits mixed light of three or more different light spectra and thereby has a particularly small Oblichtabstrahl St. The light field can thus be reduced in area.
  • the light field is suitable for emitting white light of a particularly natural light color temperature.
  • the circular sectors are preferably designed for emitting red, blue light and light from a further light spectrum, which is generated by a phosphor.
  • This further light spectrum can be, for example, light from the green and / or yellow light spectrum.
  • circular islands can be provided for emitting red light, so that in this case no red light would have to be provided by the circular sectors.
  • the light field has a diameter of 16 mm or less.
  • the LED module according to the invention is adapted to implement a lamp with small reflector sizes.
  • the LED module further comprises a light diffusion plate, which is arranged at a distance from the light field in the light emission direction of the light field.
  • the light diffusion plate gives the LED module a more homogeneous color impression, i. the scattering of the light improves the mixing of the different light spectra emitted by the light field.
  • the light diffuser also makes it possible to generate a diffused light and adjust the brightness of the LED module.
  • the light diffusion plate may additionally be provided with a phosphor, for example with an additional phosphor layer or embedded phosphor particles. The diffuser is then suitable for influencing the color or color temperature of the light emitted by the LED module as a whole.

  • the sheet sectors may be a prefabricated component which is mounted on a module plate of the LED module.
  • planar sectors of the light field are separated from one another by dams.
  • the two-dimensional sectors of the light field comprise a transparent potting compound or a potting compound containing a phosphor.
  • the individual sectors of the light field are defined in the LED module by the limiting dams and in the spaces between the dams a potting compound is filled to make the sectors flat.
  • the potting compound may consist of a transparent potting compound with added phosphor, which is present for example as a powder undissolved in it or as a phosphor particle.
  • the potting compound may also contain dissolved phosphors, i. it can be a phosphor potting compound.
  • a phosphor is generally a material that is excitable by light and then emits a secondary spectrum of light.
  • a phosphor may therefore be a light color conversion material.
  • the phosphor is a phosphor or a fluorescent material. Secondary light from the yellow and / or green spectrum is preferably emitted by the phosphor.
  • planar sectors are designed at least for emitting light from the red light spectrum, light from the blue light spectrum or light from a further light spectrum generated by a phosphor.
  • the present invention understands light from the red light spectrum light having a wavelength between about 630 and 790 nm, light from the blue light spectrum light having a wavelength between about 390 to 480 nm, light from the green light spectrum light having a wavelength between about 480 and 560 nm and under light from the yellow light spectrum light of a wavelength between 560 and 630 nm.
