Definitions

  • This invention relates to the field of lighting elements.
  • the invention refers in general to a lighting system with light-emitting diodes which enables the distribution of the light emitted by the diodes to be controlled. It has uses in all kinds of lighting facilities for both domestic and industrial or public use.
  • US patent application US 2008/0231162 A1 relates to a lighting device which includes a light source designed as a strip of light-emitting diodes and at least two panels on which, alternately, the respective transparent areas and areas made up of the respective different-coloured phosphors are defined, with the panels being designed to move relative to each other and also relative to the light source, either in a linear direction or rotating direction, in order to gradually overlap the transparent areas and areas with different phosphors of the respective panels.
  • This enables the radiation spectrum, that is to say the colour, to be varied and more specifically the colorimetric properties of the light source, taking advantage, so to speak, of the principle of additive synthesis for the generation of colours.
  • an RGB model is created which is similar to that used in colour television and enables a wide range of colours to be synthesised; but all this without mentioning the possibility of modifying the light distribution pattern of the beams generated by the LEDs.
  • Patent application WO 2005/093319 A1 relates to a lighting system comprising a means for generating a convergent light beam with a central axis and a lens situated substantially around the central axis, as well as a means to move the lens in relation to the light generation means.
  • a lens for example, a plano-concave lens moves along the aforementioned central axis, the width of the light beam can be changed and when a lens, for example, a bi-concave lens moves perpendicular to the central axis, the exit angle of the light beam is varied.
  • the possibility of grouping together several lenses with different light distribution patterns in order to change alternately between various types of light beam distribution patterns is not considered here.
  • patent application ES 2339209 A1 in the name of the applicant, relates to an optical system made up of a panel of electro-luminous diodes (LEDs) arranged longitudinally and equidistant from each other and a single mobile optical part made up of a periodic strip, with a period equal to the distance between the LEDs, formed by sequences of lenses with different light distribution patterns.
  • LEDs electro-luminous diodes
  • this system by means of a longitudinal movement of the mobile optical part in relation to the LEDs, the type of lens that collects the light from the LED is selected and, consequently, it is possible to vary the width and distribution of the resulting light beam with the appropriate choice of lens.
  • This system is adapted to linear lighting and is designed as a single optical stage implemented by a single lens, but does not enable its use in floodlight-type circular optics systems.
  • the objective set is to develop a system of the type indicated which initially enables the problems of the above technique to be solved.
  • the system is made up of a panel of LEDs with a plurality of individual light-emitting diodes and an optical device with a plurality of individual optical structures forming groups with different patterns for different light distributions which are repeated sequentially in each group.
  • the optical device is arranged so as to move in relation to the LED panel in such a way that its respective light beams fall on the optical structures of each group with a particular common light distribution pattern.
  • the system is characterised as follows:
  • the main advantages of this device include, but are not limited to, the following:
  • the lighting system according to the invention in general referred to under reference number (1), is essentially made up of an LED panel (2) and an optical device (4) which is arranged so as to rotate in relation to the LED panel.
  • the LED panel (2) consists of a plurality of individual light-emitting diodes (3), whilst the optical device (4) is equipped with a plurality of individual optical structures (5) which form groups (6) of different optical structures for different light distribution patterns which are repeated sequentially, as will be explained in further detail below.
  • the optical device (4) occupies an operating position such as that shown in figure 2
  • the light beams of each individual LED (3) fall on optical structures (5) of the groups (6) which have a common first light distribution pattern, in this case an intensive light pattern which is shown in the figure with barely diverging arrows; however, when the optical device (4) turns and moves to occupy another operating position as is shown in figure 3 , the light beams of each LED fall on other optical structures (5) of the groups (6) with a different second common light distribution pattern, in this case an extensive light pattern which is shown in the figure with arrows which noticeably diverge.
  • each of the individual LEDs (3) is equipped with its respective reflector/lens (7) in order to control and direct its light beam in a normal direction to the LED panel (2).
  • the LED panel (2) is designed as a circular panel with a plurality of individual light-emitting diodes (3) which are distributed so as to occupy their respective circumferences concentric to the centre Op of each panel in positions Rpi-Apj, which are angularly equidistant, where Rpi is the radius of a respective circumference in the panel and Apj is the angular coordinate of a polar system which originates in the aforementioned centre of the panel.
  • each group (6) are distributed so as to occupy their respective circumferences concentric to the centre Od of the disc in positions Rdl-Adm, which are angularly equidistant, where Rdl is the radius of a respective circumference in the disc and Adm is the angular coordinate of a polar system which originates in the aforementioned centre of the disc, these positions matching the positions occupied by the associated individual LEDs (3) of the LED panel (2).
  • the individual optical structures (5) of each group (6) are arranged with the same angular separation Bh, and that this separation is angular, sufficient for only one of the optical structures (5) of each group (6) to collect the light beam of the associated individual LED (3) when the optical device is turned to an operating position; nevertheless, even though the separation between optical structures (5) of each group is not shown, it may be adapted so that adjacent optical structures may partially collect the light beam coming from a single individual LED (3).
  • the optical device (4) essentially has the shape of a disc and is designed to turn around an axis E which extends between the geometric centre OP of the LED panel (2) and the geometric centre OD of the rotating disc (4). It can therefore move between a plurality of discreet operating positions separated angularly such as those shown in figures 2 and 3 .
  • the LED panel (2) can be designed with three circumferences of individual LEDs (3), the optical device being arranged with three circumferences of individual optical structures (5) and each respective group (6) consisting of only two individual optical structures for two different light distribution patterns, for example an intensive distribution pattern and an extensive distribution pattern.
  • the number of circumferences occupied by the LEDs and the individual optical structures may be chosen on a discretionary basis according to the chosen lighting application.
  • the number of optical structures of each group (6) may be two or more, with the light distribution patterns consisting of one intensive pattern and another extensive pattern, and some even having other light distribution patterns; the only important thing according to the invention is that the sequence of light distribution patterns must be repeated in the same order for each group (6).
  • the optical device (4) in the shape of a disc is mounted on a guide support (8) with an annular guide groove (80).
  • driving means (9) can be designed which are adapted to move the optical device (4) either progressively/continuously or discontinuously/step by step between the operating positions in which the light beam of each individual LED (3) of the LED panel (2) either falls only on the individual optical structures (5) of the groups (6) which have a certain common light distribution pattern or the light beam of the associated individual LED (3) falls on two or more adjacent optical structures (5) of each group (6).
  • the driving means (9) are symbolically shown as being associated with axis of rotation E of the optical support in order to show that their function is to rotate the optical device (4), however, they may be arranged in the system (1) in any other technically appropriate manner.
  • the individual optical structures (5) can be designed as lenses to shape the light beams, for example with intensive or extensive patterns.
  • concave lenses of the type shown in figure 8A could be used; however, it would also be possible to use convex lenses which provide intensive or extensive distributions, cylindrical or prismatic surfaces, not shown, which can offer distributions without rotational symmetry such as elliptical light patterns, conical lenses which have annular patterns, or Fresnel lenses which produce a specific pattern, which are not shown.
  • the optical structures (5) can be respectively designed as matrix groupings of concave, convex, cylindrical, prismatic, conical or pyramidal micro-lenses (50), which provide similar optical characteristics in a limited space.
