Description

Technical field

The technical solution generally relates to a method of generating a change in the illumination intensity distribution in the space by online remote adjustment of the luminous intensity curve of controlled LED light sources. The technical solution also concerns the design of the light module itself designed for this purpose. The technical solution generally falls within the lighting technology.

BACKGROUND OF THE INVENTION

In the state of the art, space lighting systems are generally known. surfaces either by individual light sources or by distributed light sources. Usually, the lighting of the interior is subject to constant requirements, which are met by the installation of individual light sources already in the construction of buildings or interior furnishing. This means that the permanently installed light source had no variability in the illumination of the work area or space. It was only possible to dim the illumination by dimming but equally throughout the room.

It has not been possible to change the position of the light spot on the desktop in a conference room, for example.

Especially in the field of cultural events, for example when lighting a theater scene, the light spot can be changed on the surface or in the space by way of directing the reflectors in several axes or by shading these reflectors or controlled dimming of whole groups of reflectors.

A disadvantage of the lighting systems described above is that they are not suitable for lighting in particular in the interior of offices or homes.

The aforementioned drawbacks have prompted to propose such a method of creating a variation in the illumination intensity distribution in the space and a light module, where the desired effect would be achieved by simply constructing the luminaire. This effort results in a method of generating a change in the illumination intensity distribution in space and a light module further described in this technical solution.

The essence of the technical solution

The aforementioned drawbacks are substantially eliminated by the method of creating a variation in the illumination intensity distribution in the space according to the present invention, which consists in that it is achieved by controlling the emission intensity of individual or groups of LED lamps with symmetrical and asymmetrical reflectors. This means that the light output from the reflectors as optical systems is influenced by controlling individual groups of LED light sources. By controlling individual groups of light sources different light outputs are obtained from groups of symmetrical and asymmetrical reflectors. The optical symmetrical reflector system creates a deep luminous intensity curve. The optical array of asymmetric reflectors creates an asymmetric luminous intensity curve. The interaction of the deep luminous curves with the asymmetrical luminous curves changes the distribution of the illumination in the space and thus on the illuminated surface. The transition from a deep symmetrical luminance curve to an asymmetrical luminance curve can be smooth, stepped or precisely defined by the user. The luminance curve (LIDC) changes when the groups of LED light sources gradually dim.

The above method of generating a variation in the illumination intensity distribution in a space is carried out by means of a light module according to the invention, which consists of at least one LED light source with a symmetrical reflector and at least one LED light source with an asymmetric reflector. The number of LED lamps with a symmetrical reflector and the number of lamps with an asymmetrical reflector depend on the type of luminaire and the requirements imposed on it, such as the power, size and shape of the illuminated area. For the implementation of luminaires where undesirable glare would occur when looking directly into the reflectors, the LED light sources can be equipped with satin Gaussian diffusers.

In a light module for generating a change in the illumination intensity distribution in a space according to the invention, the at least one asymmetric reflector can be oriented with its asymmetric surface in the axis of the LED light arrangement and / or can be oriented perpendicular to the axis of the LED light arrangement. The variability of this arrangement is great because it allows one part of the asymmetrical reflectors by its asymmetric surface to be oriented in the axis of the LED light arrangement and / or the other part of the asymmetric reflectors by its asymmetric surface to be oriented perpendicular to the axis of the LED light arrangement. The asymmetric reflector is a rectangular structure with four walls, where its first and second opposing asymmetric surfaces are formed into center-center circles with different radii. High variability is also permitted for the LED light source itself, which consists of at least one light emitting member. For the purposes of this invention, the light emitting members used in the LED light source are all prior art LEDs, LED chips, LED multicips, LED modules, and similar light emitting members in all prior art constructions. Preferably, the LED light source comprises four light-emitting members. Such a quadruple can be fitted with two light-emitting members with a warm white color of light into one diagonal and two light-emitting members with a cold white color of light into a second diagonal. In this case, the light module comprises an arrangement of LED light sources which can be arranged in groups side by side and / or in groups one behind the other. The light module for generating a change in the illumination intensity distribution in the space according to the invention is characterized by a construction where LED light sources are placed on a carrier with symmetrical reflectors, asymmetrical reflectors and satin Gaussian diffuser as well as connectors for connection of controlled current sources. LED lamps are fitted with a heat sink as required.

Alternative solutions of the light module allow it also to include current sources connected via inputs to LED light sources, or possibly a control block for the control of current sources. As far as the construction permits, the light module may also include the remote control receiving circuitry for the control of the power supply and possibly the power supply itself or the power supply input from the central mains.

Advantages of the method of creating a variation in the illumination intensity distribution in the space according to the present invention and the light module itself are that by controlling the intensity of the individual LED light sources and using a geometrically defined optical system, it achieves the desired variation in the illumination intensity distribution.
