Definitions
- the present application relates to high-power LED floodlights and floodlights using them according to the preamble of claim 1.
- lighting class III for general training and recreational sports.
- lighting class III is the most frequently realized in terms of number, since these are lighting systems, as they are very widespread at a variety of regional sports venues. Numerically, these are by far ⁇ times the sports field lighting systems that are created at the highest level of requirements and operated, for example, for stadiums of the soccer Congress.
- the evaluation of sporting events by television broadcasts has completely different requirements for sports venue lighting than the daily operation in relation to a safe training operation or smaller regional competitions requires, which usually do not require medial transmission.
- the German football league (DFL) are here ⁇ license requirements before in terms of floodlighting systems for stadiums the 1st and 2nd Congress.
- a minimum illuminance is defined at a height of 1.5 m above the playing field.
- the corresponding specifications on the required minimum illuminance levels in recent years are changing towards stronger illuminance levels, since high light values are required, in particular due to the increasing demands on the imaging media transmissions, for example with regard to slow-motion rendering.
- lighting requirements for HDTV require a minimum illuminance of 2000 lux.
- Further targets are set by, for example, the European Football Federation (UEFA) and the World Football Federation (FIFA).
- UEFA European Football Federation
- FIFA World Football Federation
- Luminaire also discloses an arrangement on a support frame, wherein a plurality of individual lamp body is to be arranged on a support frame.
- the lamps are arranged angled towards a central beam axis in the edge area, whereby a large-area illumination from ⁇ for example, a sports facility may be possible.
- the inventive concept now goes beyond this state of the art, but at the same time uses the best ⁇ Henden planning requirements in terms of lighting towers. That is, it is attempted to illuminate the sports field more evenly and completely despite the limited opportunities that are given by the six relatively low floodlight poles surrounding the sports field.
- LED floodlights are arranged on the existing or in a similar form newly constructed floodlight poles, which are not designed as a single high-intensity spotlight in the meaning of the prior art, but the LED spotlight with articulated LED spotlights illuminating from a combination of the sports field exist, which are directed in particular in the corners and on the outer lines of the playing field in addition, so as to be able to reach a neces ⁇ sary light intensity in the area, which are only weakly lit in the prior art.
- a corresponding exemplary diagram of the illumination will be explained in more detail later with a view to the drawings.
- the inventive concept of the flood ⁇ lighting system provides that the novel floodlight various ⁇ orientable LED spotlight comprising and fixing points can be arranged at the Flutlichtmast at the usual loading on a common, the individual LED lamps supporting Trä ⁇ substrate structure were. It is essential that these are LED spotlights which have a single high-power LED chip as light source and not a large number of individual LEDs arranged in a planar manner next to one another, as in the prior art, for example, US 2015/0308655 A1 is disclosed. These planar single-LED arrangements used in the prior art also require mat-like arranged plastic lenses or lens arrays, which are assigned to the respective individual LED, or as in the case of US 2015/0308655 Al Fresnel lenses.
- the combination of LED chip and reflector optics has another key advantage, which is especially relevant in the field of floodlighting. Since the floodlighting should enable the usability of the sports field for the active athlete as well as the view of the audience at the edge of the sports field or on stands, it is a key concern to minimize the glare from the floodlights for both groups. Again, the previously widespread planar arrangements of a variety of LEDs with plastic lenses are very disadvantageous, since the parties involved in a look to The floodlights are strongly blinded, since they look directly at the LED bulbs.
- the arrangement according to the invention causes the ext ⁇ rem high-intensity LED chips are arranged reset in the LED spotlight, and so the pre-set reflector optics reduces di ⁇ direct view of the LED light source.
- the pre-set reflector optics reduces di ⁇ direct view of the LED light source.
- deliberate scattering or bundling is deliberately achieved by the choice of a suitable reflector optics , with it being possible to significantly reduce blinding of active persons and spectators.
- each LED floodlight includes 4 LED spotlights, which are formed as described at least from a housing), a heat sink, a reflector optics and a high-power LED chip, the LED spotlights in pairs a support frame with joints are arranged. It forms as an upper LED pair of emitters, which is aligned parallel on a common support member and provided with a Reflektorop ⁇ tik, which causes a narrow beam angle, whereby the light emission of this LED emitter pair strengthened aligned and thus overcome more distances ⁇ to reach the middle area of the sports field.
- the arrangement above the second lower LED emitter pair is deliberately chosen because the lower pair is intended to cover Flutlichtmast regions near and in an arrangement above could not freely radiate ⁇ .
- a lower LED emitter pair is now in contrast to the upper statically parallel aligned pair each mounted on a separately orientable support member and provided with reflector optics, which cause a wide beam angle, whereby the light emission of this LED emitter pair can be aligned separately targeted illumination of the near the floodlight mast near the edge Areas of the sports field. On the other hand is caused by the wide ⁇ ren angle that these areas can be near the mast to the comparatively short distance area ⁇ shines.
- Pair of emitters due to the housing used with reflector optics a narrow beam angle between about 7 ° and 25 ° for the long distance and the LED emitter pair forming the LED spotlight a wide beam angle for the short distance between about 40 ° and 60 °. In this way, the mentioned illumination is specifically possible.
- a cross beam is in this case on an approximately U-shaped base support which is at Flutlichtmast to Fixed To ⁇ gene located which carries a pair Anord ⁇ voltage of two LED floodlight lamps which only about a pivot axis in their viewing angle on the sports field can be changed.
- Two other LED spotlights, which independently and independently of the paired LED spotlights in two joint planes are pivotable, so they can be aligned to any point of the sports field.
- Luminaires provided in order to optimize the uniform distribution on the sports field by an advantageous overlap of the light fields formed from the individual emissions.
- An alternative design of the floodlight system provides ⁇ in that special support frame arrangements of the floodlights are pre-designed so that even without later alignment of the individual lights on the support frame, the exact alignment is achieved to the sports field. This is determined by the parameters of the exact arrangement of the floodlight pylons on the lateral edges of the sports field, the height of the arrangement of the floodlights on the corresponding floodlight masts and the basic limitation or size of the sports field itself.
- a significant advantage and thus a compelling aspect to the economic application of LED lighting at sports fields here is that the inventive flood ⁇ light system to the usual in the art loss of Lich tabstrahlung, tet either areas of the sports field illuminated that already are sufficiently illuminated or on the outer edges of the sports field to be illuminated from radiate ⁇ minimized.
- erfin ⁇ tion is provided according to that the different LED spotlights that work together in a floodlight, also can be made up differently in terms of both their light output and in terms of their appearance. Therefore, according to the invention, different reflectors are used in the LED emitters used in common in a floodlight.
- Figure 1 is an arrangement of flood lights on
- FIG. 2 shows a high-performance LED according to the invention.
- FIG. 3 shows a high-performance LED according to the invention.
- Figure 4 shows a support frame of the invention
- FIG. 5 shows a radiation pattern for illuminating a
- the further figures 2 to 4 relate to the high-performance LED floodlight 1 according to the invention and the here ⁇ for newly developed support frame.
- FIGS 2 and 3 show in this case also the mounted LED spotlights, 4 LED spotlights are articulated in this design on the support frame.
- These LED radiators are formed from a rear heat sink 5, to which a housing 6 connects, in which not shown the LED chip ⁇ as this vortex the reflector optics are arranged.
- This structural unit is completed by a front ⁇ disc 7, whereby the LED spotlight can be made completely closed, the heat dissipation from the LED chip but is fully secured by the directly back to this subsequent heat sink.
- LED radiators are now mounted according to the invention on support elements 4 and 4 ⁇ , wherein in the illustrated construction ⁇ form the support member 4 carries two parallel LED emitters and the two other support elements 4 ⁇ each have an LED spotlight, wo- in the support elements 4 ⁇ are formed independently pivotable.
- the support member 4 is in this case laterally hinged to the free ends of a U-shaped base body 3 of the support frame, held in the illustration by screws 10. Accordingly, a pivoting of the first carrier element 4 and the LED emitters arranged thereon can take place about a pivot axis towards the sports field.
- the second Trä ⁇ gerium ⁇ 4 are also on the first support element 4 ge ⁇ leads have, compared to the pivoting movement thereof but further adjustability to two further pivotal axes.
- a support arm 12 which is fastened to the rear side on the first support element, or forms a structural unit with it.
- Trä ⁇ ger Economics 13 are pivotable in the first joint 11 Toggle directed, in the illustrated design by means of bores in the free end of the support arm 12 as well as in the support bodies 13, which are connected by means of a connecting screw to the first Gelenkverbin ⁇ dung. 11
- the two individual LED spotlights on the second support elements 13 have a further pivot axis at a second hinge connection 8 between the second support elements 4 ⁇ and the support bodies 13, which in the illustrated design with respect to the first hinge connection 11 offset by 90 °. This ensures that these two individual LED emitters having from ⁇ reaching degrees of freedom to be able to direct it to a beechi ⁇ ge be illuminated point of the sports field.
- the support elements 4 and 4 have ⁇ rear Boh ⁇ ments to make a wiring of the LED spotlights through the heat sink 5 can.
- the LED spotlight housing 6 can be installed in different designs in a floodlight.
- the Differences 6 ⁇ and 6 ⁇ ⁇ clear that the housing 6 ⁇ ⁇ is built much shorter.
- the reflector used is built much flatter and thus has deviating Abstrahlei ⁇ properties over the reflector, which is installed in housing 6 ⁇ .
- different light emissions can be realized in a floodlight by the choice of different designs of LED spotlights in terms of reflectors, housing and LED chips, which are also still aligned differently, which illustrates the great degree of variability of these flood lights.
- FIG. 5 here shows two opposing centrally arranged lighting towers A and 4 eckennah arranged flood ⁇ lighting towers B. This is arranged in the corners floodlights B this example, with 2 of the OF INVENTION ⁇ to the invention flood lights 1 are respectively fitted, thus contributing a total of 8 LED spotlight 14 .
- 8 LED lamps 14 are according to the invention 2 per emitter pairs 15 parallel angeord ⁇ net and have respective reflector housing that allow radiation over a longer distance by the mutual gain and a closer reflector optics. Because it 2 such pairs 15 on a floodlight mast B in the corner of the square, there are also 2 of this mast B outgoing lan ⁇ ge arrows 17, which emit in the middle of the field and thus illuminate the central field area.
- This lighting scheme illustrates the great strength of the floodlight lighting concept according to the invention, since the light emission can be achieved with a very manageable number of LED high-performance lights, as these individualized are both from their radiation characteristics ago and their orientation on the field and thus It is achieved that no redundancies of the radiation take place in areas in which there is basically already a sufficient quality of light and vice versa not marginal areas and areas are neglected, the same important and should be treated the same, such as the middle of the field.
