Definitions
- the present invention relates to an optical device for a LED luminaire lamp, and in particular for luminaires that have a set of LEDs arranged forming rows and columns on a flat configuration support plate.
- the optical device of the invention is suitable both for an exterior application, such as public roads and for an interior application, such as a home.
- Luminaires are devices designed to provide artificial light by means of a light source consisting of a lamp.
- Luminaires intended for public lighting, and more generally, for external lighting are normally formed by a lamp mounted on a luminaire fixed on the upper end of a mast or support, located at a sufficient height.
- This type of lighting must comply with current regulations regarding lighting quality, and in particular in the part corresponding to the luminous flux, luminescence, surface of the illuminated area, uniformity of the luminescence of said area and glare of the source bright.
- a luminaire intended for to illuminate a public road it must illuminate a substantially rectangular surface on the ground of around 24 by 6 meters, with a level of illumination greater than 10 luxes for example and a relatively homogeneous luminescence of said area.
- Luminaires whose lighting source is formed by one or more incandescent lamps are known.
- luminaires are known whose lamp or lighting source are light emitting diodes, hereinafter referred to as LEDs.
- the LEDs are considered today, as an advantageous alternative in terms of reducing the consumption of electric energy and increasing the life span of these lighting devices.
- LED type luminaires allow to have a precision of the illumination by controlling the amount of the emitted light.
- LEDs provide a great angle of lighting, this means a great diffusion of light and many losses in an application that aims to illuminate an area away from said source of lighting formed by LED.
- the LEDs are generally associated with means of concentration of the light beams in order to unify said light beams in a focus of maximum light intensity and that is oriented towards the area capable of being illuminated.
- Another problem presented by this type of lighting devices refers to the light output of the LEDs, because this light output is relatively weak. For this reason it is necessary to associate several LEDs in order to obtain a light output equivalent to an incandescent lamp, for example. Normally, this association of LEDs is done by grouping in the form of bars or luminous points of three LEDs.
- LED type luminaires are generally used in adjustable lighting applications, so that the light beam can be oriented to illuminate a specific area, such as a lighting spot for reading in a vehicle, or A spotlight used in a theater.
- the lamps are associated with optical devices whose function is to achieve optimum illumination by treating the light beams emitted by each of the LEDs.
- Luminaires of the LED type are known (which they use as a source of LED lighting) intended for public lighting comprising LEDs or LED bars attached on a support that allows the light beam of the LEDs to be oriented in a direction such that lighting or lighting occurs. of a specific area.
- a first lighting or luminaire device is known according to the aforementioned which is described in the patent document number WO-98/33007, comprising several LEDs and means of treatment of the light rays emitted by said LEDs, in order to improve the distribution of the light beams over the area to be illuminated.
- This document proposes an arrangement of the LEDs according to different directions on an inclined support and provides, means of treatment of the light beam, through concentration means and refractive means for each LED.
- a second lighting device comprising several LEDs, a curved support that has a housing for each LED, and means for the treatment of the light rays emitted by LEDs and formed by means of reflection and means of refraction for each LED.
- the orientation of the light rays of the LEDs in the direction of the area to be illuminated is obtained thanks to the arrangement of said LEDs on a support with inclined or curved surfaces, this being relatively complex configuration so that it does not facilitate its realization or its cooling.
- the treatment of the beam of light emitted by each of the LEDs proposed in the documents described above implies a non-homogeneous luminescence on the area to be illuminated, that is, the spot Luminous obtained is formed by several zones of strong luminosity.
- a third device known and described in the patent document number US-2004/0174706 comprises a flat support that has a set of LEDs arranged matrixally and means of treatment of the light beams emitted by the LEDs, said means of Treatment comprises reflection means through slanted slats separating the columns of LED and refractive means superimposed on the reflection means.
- the treatment of the light beams emitted by the LEDs proposed by the lighting device described in US-2004/0174706 does not allow obtaining illumination with homogeneous luminescence since it is a treatment of the orientation of the light beams through LED columns obtaining a light spot composed of bands of varying brightness.
- the present invention relates to an optical device for a luminaire lamp with LEDs for the treatment of the light beams emitted by the LEDs which has a set of LEDs arranged forming rows and columns on a support plate of flat configuration comprising:

- the invention relates to a lamp with optical device for LED luminaire for the treatment of the light beams emitted by the LEDs described above.
- the optical device for LED luminaire of the invention allows to offer a homogeneous brightness of the area to be illuminated, even when the source of illumination is considerably away from the area to be illuminated (for example in cases where used for a luminaire for outdoor lighting).
