Definitions

  • the invention relates to an LED lamp with continuously adjustable radiation angle according to the preamble of claim 1.
  • Replacement lamps for AR 111 halogen lamps for example, which have 6 individual LEDs as standard, in front of which arranged on a lens array individual lenses are arranged. These replacement lamps are usually supplied with a defined beam angle in different stages (usually 10'Grad, 25 degrees, 30 degrees, 40 degrees), which can not be changed by the customer. An adjustment of the beam angle would be quite reasonable and desired by the customer.
  • the font WO 2004/034748 A1 discloses an LED-based modular lamp which employs superior optics to focus the light.
  • This optics consists of arranged in a plane single lenses, which are arranged corresponding to the individual LED and are arranged in a guide frame which engages with clips in corresponding receptacles on the lamp. It is a sliding one slidable arrangement to model (modulate?) the light beam.
  • a disadvantage of this solution is that the optics is designed to be plugged only on the lamp, which on the one hand an exact focusing is difficult, since a linear force applied in the direction of the light axis for shifting the optics and thus this is difficult to set exactly. Furthermore, it can easily come to an unintentional adjustment of the desired values when a pressure is applied to this plugged optics, or if they accidentally removed from the lamp. There is thus a lack in the solution on the one hand on the exact adjustability and on the backup of the adjusted focus.
  • a Lampertsystem which also has a number of LED bulbs, which is associated with a lens array.
  • Lens array is in this case set on an adjustable to adjust the distance between the illuminant plane and lens plane, lying in the light axis of the lamp carrier, which acts centrally on the underside of the lens array and is also guided centrally through the illuminant array.
  • the change in the distance between the lens array and the illuminant array is achieved here by a rotation of this carrier and the lens arrays arranged therein.
  • the individual lenses guided out of the lens array are thus not supplied to the lighting means in a linear movement, but are themselves brought in rotation to the lighting means. It is intended in the application to be able to achieve effects similar to those of a disco lamp by changing the lenses in their position to the bulbs.
  • an LED lamp with continuously adjustable beam angle wherein a plurality of LEDs are arranged on a support plate and an adjustable in their distance to this support plate lens plate this is prefixed, with a simple and permanent setting of Radiation angle is structurally possible.
  • the lamp should allow a homogeneous light emission despite the use of multiple LEDs, in which the individual light sources are no longer recognizable.
  • a flashlight is to be created, which also allows a simple and permanent adjustment of the beam angle constructive while realizing a good heat dissipation of the LEDs
  • the first object is achieved with an LED lamp with the features of the main claim 1.
  • the dependent claims 2 to 8 have advantageous embodiments of the LED lamp to the subject.
  • the LED lamp according to the invention in this case has a combination of features, the interaction of which cause adjustability and a luminous power, which comes very close to, for example, an original AR-111 halogen lamp.
  • a lamp with 9 LEDs is proposed, which are arranged on an LED carrier plate in a plane. Associated with these LEDs is provided in a parallel plane, a lens array in the form of a Fresnel lens array, as this one Even light emission is achieved even when using a large number of individual LEDs on a circuit board.
  • the individual LEDs in each case a Fresnel lens of the array is assigned directly independent of each selected. Angle.
  • the Fresnellinsenarray is guided adjustably in its distance from the LED level, this is achieved by a special mechanism consisting of a lens plate supporting retaining ring, which is guided by at least two vertically engaging in this guide pin so that only a vertical displacement of this lens-bearing retaining ring is possible.
  • the retaining ring enclosing a guide ring with internal thread is now arranged closed around this retaining ring, the retaining ring engages with its outer contour in the steeply formed guide thread of the guide ring, and thus upon rotation of the guide ring in an outer fixing ring of the retaining ring with the lens a vertical displacement to the LED Board towards or away from this, depending on the direction of rotation of the guide ring, takes place, wherein the respective LEDs associated Fresnel lenses of the array maintain their position on the LEDs, so the lens array does not rotate.
  • the distance between the Fresnel lens array and LED support plate is selected so that radiation angles between about 10 ° and 60 ° are infinitely adjustable. These are radiation angles, the application of which is frequent, so that the LED lamp according to the invention in a design as a radiator can replace various types of halogen radiators, which have hitherto only been offered with a fixed radiation angle.
  • defined stages of the emission angles between approximately 10 ° and 60 ° are indicated by markings on the guide ring.
  • markings on the guide ring In the change made by turning the guide ring change the beam angle of this adjusted by reading the marks accurately and subsequently easily controlled.
  • defined stages of the emission angles between approximately 10 ° and 60 ° can be predetermined by latching positions of the guide ring.
  • the guide ring engages in the rotation, for example, with corresponding projections in recesses of the retaining ring, wherein the Vetiefept each indicate a defined stage of the radiation angle.
  • the adjustability remains stepless, the detent positions serve only for orientation and securing the once set position.
  • One possible design provides for an approximately half-shell-shaped heat sink on which the LED board rests. It is a flat and aesthetic design that allow use of the spotlight in already known form.
  • Another design has an elongated approximately cylindrical heat sink, in which the cooling fins are arranged one above the other in the longitudinal direction of the radiator.
  • This design is characterized by particularly good cooling of the LED board, which can therefore also have a greater number and density of LEDs.
  • a good protection of this wiring is realized.
  • FIG. 1 shows an embodiment of the invention in the form of an LED spot, which has the structure of the invention.
  • a representation form is selected in which the individual structural components are shown one above the other in unassembled form. In the following, the components are described from top to bottom.
  • the upper component is the retaining ring 1, on whose outer surface at least one circumferential projection can be seen, which engages in the internal thread of the guide ring 2.
  • the guide ring 2 is shown below the retaining ring 1 and can be seen in a perspective view of the quite steep internal thread.
  • This guide ring 2 is seated in a fixing ring 3, in which the guide ring 2 engages positively.
  • the Fresnel lens array 4 is shown, which is mounted in mounted form on the underside of the retaining ring 1 in the lens ring 5, which is shown below the Fersnellinsenarrays 4.
  • the lens ring 5 in this case has two oppositely arranged holes 6, in which two below of the lens ring 5 shown vertical guide pin 7 engage to secure the only vertical displacement of the lens ring 5 with attached retaining ring 1. Below this guide pin 7, the LED board 8 is shown, are arranged on the in the illustrated embodiment, nine individual LEDs 16 at a uniform distance from each other.
  • This LED board 8 is in turn placed on an LED board holding plate 10, which in turn is held in a mounting ring 11. Finally, these assembled components are inserted into a heat sink 12 to dissipate the thermal energy released during the Lichabstrahlung.
  • FIGS. 2 and 3 is now a section through the LED spot according to the invention shown, which is a type of construction, which is composed of the components described above.
  • the uppermost component here is the retaining ring 1, which has on its underside the Fresnel lens array 4, which is held in the lens ring. It is clearly in FIG. 2 recognizable that the retaining ring 1 is applied to the lens body 4 at an upper stop of the guide ring 2, and thus the maximum distance between the LED board 8 and the Fresnel lens array 4 is taken.
  • the steeply extending internal thread of the guide ring 2 can be seen below the Fresnel lens array 4, the steeply extending internal thread of the guide ring 2 can be seen. Left and right of the retaining ring 1 are also the vertically arranged guide pin 7 can be seen, which prevents rotation of the arranged on the Fresnel lens array 4 single lenses with respect to the underlying individual LED's 16.
  • the guide ring 2 is arranged so that it can be easily rotated with your fingers. He is in this case held in the below fixing ring 3, which makes the connection between the heat sink 12 and the guide ring 2. On the underside of the LED spot, the connection contacts 15 to the power source, mounting rivets 14 and a cover plate 13 are also shown.
  • FIGS. 4 shows another design, in which a cylindrically constructed heat sink 12 is used with superposed cooling fins with the advantages already described. Within the heat sink extends vertically through a continuous bore, which serves to connect the LED board 8.
  • FIG. 5 shows a flashlight according to the invention, which has an LED lamp according to the invention as the light source, wherein between the battery compartment of the flashlight and the LED support plate 8, the heat sink 12 is arranged exposed. In this way, it is ensured that the heat generated during operation can be dissipated easily and that the lamp can not overheat.
  • FIG. 5 illustrates here that this embodiment of the lamp as a flashlight with a rod-shaped battery compartment has the basic structural components that allow the adjustment of the radiation angle, namely the retaining ring 1, on which the lens array 4 is fixed and the outer guide ring 2 in its distance to LED support plate 8 is variable.
  • the number of LEDs 16 on the support plate 8 is variable depending on the application and size of the flashlight.
  • FIGS. 6 and 7 show a different design, in which case the actual lamp has the described structure. Again, in this design, the lens array 4 of the Fresnel lenses without rotation relative to the LEDs 16 can be adjusted. This is especially the case FIG. 6 in which the components are shown above each other.
  • FIGS. 8-15 represent further designs of the LED lamp according to the invention, wherein the FIGS. 8-11 a design as a replacement for lamp designs of the PAR30 and the headlights Figures 12-15 represent a LED lamp according to the invention as a replacement of the headlights PAR38.
  • the basic structure also corresponds to the previously described LED lamps in these designs.
  • the displacement is effected by the rotational movement on the frontal guide ring 2.
  • the now present design also has an LED driver 19 which is arranged in an LED driver housing 20 below the heat sink 12.
