Definitions
- Lighting device for illuminating objects or buildings
- the invention relates to a lighting device for illuminating objects or buildings, with a circuit for operating at least one lighting element.
- halogen spotlights in which a lighting element, namely the halogen tube or bulb, are introduced into a housing with reflecting elements approximately in the focus of these reflecting elements, in order to illuminate building walls, for example.
- Such halogen lamp devices have the disadvantage that they have a relatively large design and a relatively small size in relation to the size of the design Enable luminosity. Furthermore, such known lighting devices have the disadvantage that they consume a relatively large amount of energy or power.
- a lighting device for illuminating objects or buildings with a circuit for operating at least one lighting element which is further developed in that several lighting elements are combined in one unit.
- This lighting device enables a compact design in which objects or buildings can be illuminated with a high light intensity.
- unit means in particular also holder or assembly.
- the unit preferably comprises more than two lighting elements. Furthermore, the unit preferably comprises more than five lighting elements. The unit further preferably comprises more than fifteen lighting elements.
- the light-emitting elements preferably comprise light-emitting diodes
- a particularly compact design is possible and furthermore energy-saving illumination of objects or buildings.
- a circuit is preferably used which switches the light-emitting diodes in an intermittent light sequence, the fre- frequency is above the frequency that a human eye can resolve.
- the objects or buildings illuminated by the lighting device appear in a uniform light, at the same time further energy being saved.
- light-emitting diodes are also luminescent diodes and are also referred to in particular as LEDs.
- the light-emitting diodes are preferably operated with a higher current than that specified by the respective manufacturer, so that a higher intensity can be achieved.
- light emitting diodes are preferably used which emit an essentially white light.
- a circuit arrangement for operating the light-emitting diodes according to patent application No. 199 30 343.9 by the same applicant is preferably used.
- At least one converging lens is preferably provided per lighting element, so that focusing of the rays emanating from the light-emitting diodes is possible.
- the light-emitting diode with the converging lens is preferably a structural unit.
- the lenses are preferably aspherical. With this measure, a substantially uniform beam of uncharacteristic sti k of the lighting element can be achieved with a non-uniform radiation characteristic of the light-emitting diodes.
- the lens preferably has a focal length of 2.5 cm or 40 diopters.
- the circuit comprises a step-down converter. With this step-down converter, it is easily possible to set the desired brightness.
- the circuit further preferably comprises a step-up converter.
- a step-up converter is particularly useful if the available output voltage is lower than that required to operate the lighting elements and in particular the light-emitting diodes.
- a step-up converter is preferred when using batteries or accumulators, ie primary elements or secondary elements.
- the distances between the lenses and the associated lighting elements can preferably be predetermined.
- the size of the light spot on the objects or buildings can be specified.
- the respective distances are preferably of the same size. Furthermore, the distances between the lenses in the associated lighting elements can preferably be adjusted by means of common facial expressions.
- a rotating element is preferably used, which is in engagement with gearwheels which, for example, moves the lenses via a thread relative to the light-emitting diode or via a 1-axis Mimi k.
- the light-emitting elements are preferably operated by means of a circuit in which a diode is connected in parallel in the opposite direction to the light-emitting elements and in particular in parallel to the light-emitting diodes, and a resistor is also connected in parallel to these two elements.
- chain or series connections of such circuits comprising light-emitting diodes, are provided.
- diodes connected in parallel and resistors connected in parallel are connected in series, with several chains being connected in parallel, so that one A large number of light-emitting diodes or light-emitting elements can be operated uniformly.
- the diodes arranged in parallel serve as protection against overvoltages.
- the resistors serve to provide a uniform voltage across the respective lighting elements. As a result, 3,000 chains with 10 LEDs each can be operated, for example, if the primary circuit is secured with an IOA fuse.
- At least parts of the circuit are preferably cast in a casting resin, an epoxy resin or a polyester resin, so that corresponding lighting devices are very insensitive to impact.
- 1 is a plan view of two different sized lighting devices in a schematic representation 1,
- Fig. 4 is a circuit diagram for several light emitting diodes
- the same or corresponding parts are denoted by the same reference numerals, so that a renewed introduction is dispensed with and only the deviations of the exemplary embodiments illustrated in these figures from the first exemplary embodiment are explained:
- Fig. 1 shows a plan view of two different sized lighting devices in a schematic representation. A slightly smaller lighting device is shown on the left side and a slightly larger lighting device is shown on the right side.
- LEDs with optics 10 are each mounted on a holder 11.
- the holder can be a plexiglass pane, for example.
- 24 LEDs with optics are combined in one unit and on the right side of FIG. 1, 96 LEDs with optics 10 are combined in one unit.
- a flashlight is shown schematically in perspective.
- a rotary handle 13 is attached to a flashlight housing 12.
- Three LEDs with optics 10 are provided on a holder 11.
- a gear is set in motion that is in engagement with holders 16 of the LED with optics 10.
- the distance between the lens 15 of the lighting element 10 and the light-emitting diode 14 can be changed.
- the lens 15 is in firm engagement with the housing 16, as shown schematically in FIG. 3, and the light-emitting diode 14 is designed to be displaceable.
- a light-emitting element is schematically shown that comprises a lens 15 and a light-emitting diode 14.
- the lens 16 is in firm engagement with the housing 16.
- the light-emitting diode comprises an active region 17 of the light-emitting diode and electrical connections 18.
- the light-emitting diode is fastened on the holder 11.
- the housing 16 is, as indicated by the arrows, movably arranged with respect to the light-emitting diode 14. This allows the beam characteristic of the lighting element to be changed.
- the housing 16 can be moved via a toothed rack 19 which is directly or indirectly connected to the rotary handle 13.
- the lighting elements according to FIG. 1 can be operated, for example, with a circuit as shown in FIG. 4.
- a circuit is shown schematically in a circuit diagram in FIG.
- An AC voltage of 230 or 115 volts is transformed by a transformer 20 to a suitable voltage.
- This is converted into a DC voltage by the rectifier, which is indicated by the diodes D1 to D4.
- This is followed by chains of light-emitting diodes D9 to D12, D16 to D18, D22 to D24, D26 and D28 arranged in parallel.
- a diode D5 to D8, D13 to D15, D19 to D21, D25 and D27 are connected in parallel to the respective light-emitting diodes.
- Resistors R2 to R5, R7 to R9, R11 to R13 and R14 and R15 are also connected in parallel.
- the diodes connected in parallel serve to absorb voltage peaks, i.e. as protection against overvoltage.
- the resistors serve to ensure a uniform voltage drop, so that the life of the LEDs is increased.
- the resistors connected in parallel are approximately in the range of 10 kn. The LEDs flicker due to this approximately at the mains frequency. However, this flickering is not visible to the human eye, so that there is an impression of a uniform glow.
