Definitions

  • the illustrated in the figures embodiment of the LED device according to the invention 1 has 81 LEDs 2, which are relatively densely packed in a stable but in both Surface directions stretchable rubber layer 3 are embedded. This is in Figs. 1 and 3 for the spot position of the embodiment of the LED device 1 according to the invention shown.
  • the 81 LEDs 2 provide a lamp with approximately circular Periphery, as can be seen from Fig. 3.
  • the rubber pad 3 serves as elastic support for the LEDs 2.
  • the rubber base 3 with the LEDs 2 embedded therein is clamped in a frame 5.
  • This frame 5 also receives a mushroom-shaped punch 4, which of the radiation direction the LEDs 2 side facing away by means of a wing nut 6 against the rubber pad 3 can be pressed (see Fig. 2).
  • each LED 2 is approximately 10 °.
  • the LEDs 2 are arranged so close together that their individual light cone already very close strongly overlap at the LED device 1 and to a total cone of relatively high light intensity add. This is shown in Fig. 4.
  • the radiation angle of the total light cone is in spot position about 10 °.
  • the punch 4 by means of the thumbscrew 6 from below (see Fig. 2) against the rubber pad 3, the rubber pad 3 begins to buckle. This leads to to the fact that the LEDs 2 no longer radiate all in the same direction.
  • the beam angle of the total light cone increases.
  • it is illuminated on a surface unit attributable proportion of the embodiment of the LED device according to the invention 1 emitted light compared with the proportion in spot position less, i. the light intensity decreases.
  • the reason for this is that the light cone of each LEDs 2 no longer overlap as much as they do in the spot position.
  • Embodiment of the LED device 1 according to the invention reaches its flooding position.
  • the flood position the superimposition of the light cone of the individual LEDs 2 is largely eliminated and by a simple, i. non - overlapping, spatial complement of the single LED light cone replaced. This is illustrated schematically in FIG. 5.
  • Fig. 7 shows a corresponding comparison the emission angle of the total light cone of the embodiment of the invention LED device 1 in spot position and in flood position.
  • LED device acts as an elastic support the rubber base 3.
  • the elastic backing is not necessarily made of rubber must exist. Rather, any other elastically deformable material is suitable for this purpose.
