Definitions
- the present invention relates to an LED luminaire and at least one associated system of such luminaires for illuminating inner and outer surfaces, in particular of industrial plants or surfaces with improved lighting efficiency.
- High brightness LEDs also allow outdoor or industrial lighting in high halls, warehouses, sports halls, etc.
- an LED lighting element which has a homogeneous light distribution to the target and in which an elongate lamp element includes a plurality of LEDs arranged along a longitudinal direction, wherein above each light source is preferably arranged a lens, so that these as diffused radiators act.
- luminaires are used which, in addition to the lowest possible heat generation and thus energy savings, also guarantee a high luminous efficacy, a long service life and a uniform radiation angle which is sufficient for the specific application.
- the object of the invention is to develop an improved LED lamp or a lighting system, which causes an improvement, the lighting efficiency and at the same time by low installation costs can be realized.
- the object of the invention is achieved by a luminaire or a luminaire system, which is characterized in that the radiation sources are LEDs, which are constructed as a 3-chip LED and the adjacent chips are in each case so twisted to each other that they asymmetric abstrah- compensation of a 3-chip LED.
- the 3 LED chips are each arranged nearly 90 ° to each other, as can be seen from Fig. 2.1. In the luminance image of Fig. 2.2, the 3 LED chips can be seen.
- the 3 LED chips are not necessarily symmetrical on the. LED arranged. Since the distances in the overall system should be very short and compact, this must be taken into account in the additional optics to be used.
- optical elements which consists of at least one lens plate.
- the single lens is an aspheric that sits centrally above the LED.
- the lens formations are on the opposite side to the LED top.
- An example embodiment of this arrangement is shown in FIG. 1 remove.
- the asymmetrical arrangement of the 3-chip LEDs must be taken into account in the spacing and adapted accordingly.
- Fig. 3.1 shows a section of an arrangement of the LEDs, with the mutually rotated arranged 3-chip LEDs can be seen.
- each row of the LEDs has the same orientation from left to right (in the x-direction), but has an offset in the y-direction.
- 0 ° is the basic orientation (chamfered edge lower right).
- next row of LEDs begins a 90 ° rotation (see chamfered edge) counterclockwise over the entire x-direction (horizontal) of the board.
- next row is 180 ° rotated to the ground state. Accordingly, then the next row is rotated by 270 °.
- the successive LED row then starts again at 0 ° and then on the same principle.
- the repetition of this series is arbitrary and dependent on the size of the respective lens plate or the lighting system.
- the reason for the LED rotation is the asymmetric 3-chip arrangement within the LED. If you would not turn the LED's, then the entire light would be extremely "squinting" .That means the spot actually generated on the ground is no longer in the Lot but drifts away from the Center. The aim of the invention was also precisely to avoid this and to increase the lighting efficiency.
- Fig. 4 in turn, a detail as a side view of the lens array at a beam angle of 60 ° and the underlying board is exemplified.
- the rotation of the 3-chip LEDs is represented by the different design.
- Fig. 5 shows an exemplary single lens. In this figure, the rotationally symmetrical contour of the single lens to the lens array can be seen.
- the distance of the lens plate to the LED top (luminous area) is 0.5 mm in this embodiment.
- the lens plate in this case is 3.5 mm thick.
- the lens sits centrally over the LED.
- the minimum thicknesses of the lenses in one embodiment are 2.0 mm. 392 LEDs were processed.
- FIG. 6.1 shows a section of the exemplary lens array.
- FIGS. 6.2 again show an example of a lens plate from different views (side view tilted and top view).
- the modular character of the lens plate is clearly visible. This makes it possible in an advantageous manner to adapt the requirements according to the surfaces to be illuminated and modular.
- This exemplary optic consists of hexagonally arranged lenses.
- the lens plate is made of a suitable plastic (polycarbonate, PMMA etc.).
- these lens plates is at least one recess for space-saving supply or implementation of terminals and lines of or to Board provided (see in Fig. 6.2, left side of
- the solution provides uniform light distribution with fewer LEDs than known prior art solutions and with less glare.
- Fig. 7 shows from the result of a simulation of the emission of such a 60 ° - light.
- Glare At 50 ° the intensity has dropped to 2% of the central light intensity.
- Luminous flux in the range> 50 ° F b i e n d 61 Im.
- Fig. 8.1 shows the section through the radiation distribution with an angular distribution of a 60 ° optic.
- Fig. 8.2 shows the iso-candela plot of the radiation distribution.
- the demands on the light distribution and the glare can be realized according to the invention with the 3-chip LED and the additional optics.
- a central light intensity of 5600 cd is achieved at a half-angle of 58 ° (measurement 5100 cd at 55 °).
- the task of the invention is realized with the 3-chip LED and the additional optics. With 396 LEDs, each operated with 24 Im, a central light intensity of 8600 cd is achieved at a half angle of 59 ° (measurement 5100 cd at 55 °). In the angular range beyond the 50 °, there is still a luminous flux of 60 Im. This corresponds to 0.7% of the total luminous flux in the distribution. In the measurement it is 600 Im out of a total of 5300 Im (11.3%). The glare is thus significantly reduced.
- the inventive lights can also be used as lighting systems.
- the special effect of the luminaires is that the modular design is suitable for optimal illumination in rooms with different heights and
- a further preferred embodiment relates to an improved LED lamp for generating an elliptical or oval illumination surface.
- individual lenses are used that consist of biconical surfaces.
- the single lens consists of a biconical surface, which is designed elliptical due to the trimming in height.
- FIG. 9.1 shows a biconcave single lens as a side view and in FIG. 9.2 as a detail from the top of the lens array with a beam angle of 30/60 °.
- the distance of the lens plate to the LED top (luminous area) is 0.5 mm.
- the lens plate is 5.5 mm thick.
- the basic thickness of the plate is 2.0 mm.
- On the LED side facing the lens plate is no optics,
- the individual lenses are arranged longitudinally (narrow side in x-direction, or 30 °) to the horizontal (x-direction) above the LED 1 s
- the long drawn spot ensures that only the useful light flux in the target plane (long narrow aisle warehouse) really arrives and is therefore illuminated.
- FIG. 10.1 each depict a section of an exemplary lens array with biconcave single lenses.
- this image one recognizes the oval contour of the single lens to the lens array. This oval contour creates an oval spot on the surface to be illuminated.
- the beam angle (half width) is, as shown, over the narrow side (x-direction) 30 ° and over the long side (y-direction) 60 °.
- FIG. 10.2 again shows, analogously to FIG. 1, an example of an arrangement using lens arrays with biconcave individual lenses.
- FIG. 11 shows the result of a simulation
- FIG. 12 shows the iso-candela plot of the radiation distribution of the angular distribution of the 30/60 ° lamp.
- the Einzellinse / n can be located on a lens plate or form a lens array in its entirety, which in turn can represent lens plates Mödulbauweise.
