Description

The invention relates to a structural component for a patio roof and / or a conservatory with at least one integrated lighting device comprising at least three series circuits each having a plurality of light emitting diodes each emitting a light of the same color, at least one power supply and at least one multiplex switch, wherein the light emitting diodes the three series circuits each emit a light of a different color, wherein the three series circuits are connected in parallel.

Furthermore, the invention relates to a patio roof or conservatory with such a structural component.

Such structural components are known for installation in conservatories, patio roofs, vertical and horizontal shading. A disadvantage of the known structural components, however, is that the lighting operation is energy intensive and require the necessary elements for the lighting device much space.

The object of the invention is to improve a structural component of the type mentioned and in particular to increase the energy efficiency of the lighting device.

This object is achieved by a structural component according to claim 1. Advantageous developments of the invention are specified in the dependent claims.

Particularly advantageous in a structural component having at least one integrated illumination device, the at least three series circuits each having a plurality of light emitting diodes, each emit a light of the same color, at least one power supply and at least one multiplex switch, wherein the light emitting diodes of the three series circuits each a light of another Emit color and wherein the three series circuits are connected in parallel, it is that the series circuits are operated in the on state of the lighting device of a single power supply, the series circuits by means of a single multiplex switch with the power provided by the power supply within a defined Wiederholintervalls in Form of a sequence of the same length of time sections are controlled such that within a single time section each of the series circuit / s with a light of the same color emitting LEDs is driven / who the.

The color of the light also includes white, warm white and cold white light. The term of driving in the context of the energization of the series circuits to understand.

A repeat interval consists of equal time periods. In particular, the repeat interval is defined such that the human eye can only perceive a difference between the successive defined repeat intervals, but not a difference between the individual time periods within the defined repeat interval.

Preferably, the duration of the defined repetition interval is 1/30 second or less. The defined repetition interval may in particular consist of 16 or 32 equal time periods. The duration of a time period is then 1/480 seconds or 1/960 seconds less.

By such a determination of the duration of the defined Wiederholintervalls and the duration derived therefrom a period of time, it is ensured that no single controls individual LED rows are visible to the human eye, but only the mixed color thus produced by the human eye is perceptible.

According to the invention, the lighting device is controlled in such a way that within a repetition interval the three series circuits whose LEDs emit a light of a different color are driven in the form of a sequence of segments of equal length and within a single time segment the series circuit is illuminated by a light emitting the same color. so that a light is created for the human eye. In other words, during a single time period within a repetition interval, only the light emitting diodes which emit light of the same color are driven. Of course, the at least three series circuits of the illumination device for mixing the individual light colors to a specific color, in particular a mixed color, arranged in spatial proximity to each other, preferably within a light emitting device and / or within a single LED strip with a plurality of light emitting diodes.

By the term of driving is meant that the individual series circuits are energized. This means in the context of the invention that a controlled series connection of light-emitting diodes is energized. During the duration of the drive thus a DC voltage greater than zero volts is applied with a current greater than zero amps, whereas in times in which a particular series of light-emitting diodes is not driven, accordingly no voltage is applied to this series of light-emitting diodes.

In order to maintain the light of the particular color, in particular of a mixed color, the control is always repeated in the form of the sequence of equal intervals of the repetition interval. The effect is exploited that the human eye in a sufficiently short defined Repeat interval respectively with sufficiently short periods of time can not distinguish between the light colors of the individual series circuits, but a light of a single color, in particular a mixed color perceives. As a result, it is possible to display a large spectrum of light colors without adapting the electrical energy to be supplied and / or simultaneously controlling them without series connections with light emitting diodes emitting different light colors. In this way, the energy efficiency of the lighting device is increased and it only needs the arrangement of a single power supply and a multiplex switch.

The number of series connections of the lighting device is not limited to three. Further series circuits can be arranged, wherein the light emitting diodes of the further series circuits can emit both a light of a different color and a light of the same color as the at least three series circuits. However, a particularly preferred embodiment is designed such that it has three series circuits each having a plurality of light-emitting diodes, each of which emits a light of the same color. In this case, the arrangement of the series circuits, each with a plurality of light emitting diodes, the possibility of generating any mixed colors given the least installation effort.

In the case of the arrangement of a plurality of series circuits with light-emitting diodes which emit a light of the same color, a plurality of series circuits with light-emitting diodes which emit a light of the same color can thus simultaneously be activated within a single time interval.

In this case, only the series circuit (s) which have a light of the same color emitting light-emitting diodes are / is activated within a time segment.

As a result, energy is saved on the one hand during operation of the lighting device, since during a time period only the series circuit / s is driven, which is a light of the same color having emitting LEDs. In particular, only a single series circuit is driven during a period of time. Characterized a simultaneous control of series circuits with a light of different color emitting LEDs and thus an increased energy consumption can be avoided.

On the other hand space and cost savings, since only a single power supply and a single multiplex switch are arranged. By supplying the series circuits by means of the single power supply space is saved. By saving space, a slimmer construction of the structural component is made possible. In addition, the manufacturing cost can be reduced because only one power supply is required.

By controlling the series circuits by means of the single multiplex switch also space can be saved, so that a slimmer construction of the structural component is made possible. In addition, the manufacturing cost can also be reduced, since only a multiplex switch is required. In particular, the multiplexing switch is a demultiplexing switch which forwards the power provided by the power supply to the individual series circuits.

The structural component for a patio roof and / or a winter garden may be a support or post or rafter. Furthermore, it may be gutters or wall connections or Wandanschiussprofile or vertical elements or frame or connecting rails. Due to the fact that, according to the invention, only one power supply and only one multiplex switch must be arranged to control the at least three series connections of light-emitting diodes, the lighting device can also be integrated in very slim structural components and in particular profiles for a wide variety of applications and installation situations.

In particular, the structural component for a patio roof and / or a winter garden is designed as a profile and in particular as a hollow chamber profile, which is particularly suitable for receiving a shading device.

In particular, the structural component can be used for installation in conservatories, patio roofs, vertical and horizontal shading as a support, support posts, beams, eaves, rafters, guide rail, housing in particular for horizontal or vertical or oblique installation , By forming the structural component for a patio roof and / or a winter garden as a hollow chamber profile, one or more cable ducts and / or sewers and / or inserted or inserted reinforcement elements can furthermore be integrated into the structural component. In a preferred embodiment, the structural component has one or more cable channels and / or sewers and / or inserted or inserted reinforcing elements. Furthermore, the structural component may be formed in one piece or in several pieces as a profile.

In a preferred embodiment, of the at least three series connections, a first series circuit comprises red or magenta-colored light-emitting light emitting diodes, a second series circuit green or yellow light emitting light emitting diodes, and a third series circuit blue or cyan light emitting light emitting diodes. The light-emitting diodes of the at least three series circuits preferably form complementary colors with one another. By means of such a combination of the series connections, a large color spectrum of the light to be emitted can be represented by the above-described generation of mixed colors.

In particular, the individual series circuits each have light-emitting diodes which emit a light of one of the primary colors red, green or blue (RGB).

Preferably, of the three series circuits, a first series circuit comprises a light having a wavelength between 599 and 781 nm emitting light emitting diodes, a second series circuit a light having a Welfenlänge between 490 and 600 nm emitting LEDs and a third series circuit a light having a wavelength between 379 and 489 nm emitting LEDs on

The control of the series circuits is preferably pulse-modulated, in particular pulse width modulated (PWM) and / or pulse duration modulated (PDM). By means of a pulse-width-modulated control, a current signal of a very precise current intensity can be imaged. By means of a pulse-duration modulated control, a current signal of a very precise duration can be imaged.

In a preferred embodiment, the three series circuits are each driven with different relative turn-on durations within the respective time segment. The term of the relative duty cycle is understood as meaning a portion of the time segment during which the respective series circuits are actually activated. By means of such a control, it is possible to adapt the intensity of the respective light color to the perception of the human eye, since the human eye perceives different colors with different intensity. Furthermore, this makes it possible to lower the energy requirement of the illumination device since the activation of the respective series circuits does not take place during the entire time segment.

For example, the human eye perceives the light of the red color more intense than the light of the blue color. In this way, the relative duty of the red color light versus the blue duty light duty cycle can be shortened without the human eye perceiving a difference between the different durations of duty.

In particular, the different relative switch-on durations can be realized by means of a pulse-duration-modulated control.

Preferably, the duty ratio of a series circuit comprising red or magenta colored light-emitting LEDs is between 70 and 84%, in particular 76% of the time segment. By means of such a control, it is possible to adapt the intensity of the respective color to the perception of the human eye. Furthermore, at the same time the energy requirement of the lighting device is lowered, as the Control of the series circuit, the red or magenta-colored light-emitting light-emitting diodes, not carried out during the entire period.

In a preferred embodiment, the duty cycle of a series circuit comprising green or yellow light-emitting LEDs is between 85 and 98%, in particular 94% of the time segment. By means of such a control, it is possible to adapt the intensity of the respective color to the perception of the human eye. Furthermore, at the same time the energy requirement of the lighting device is lowered, since the driving of the series circuit having green or yellow light-emitting LEDs does not occur during the entire time period.

Preferably, the duty ratio of a series circuit comprising blue or cyan light emitting diodes is 100% of the time.

In a preferred embodiment, the power supply supplies the illumination device with a constant current. In particular, the constant current intensity can be realized by means of a pulse-width-modulated control. By means of the supply with a constant current intensity can be emitted by means of the series circuits, a light of a color which is located on the outer edge of the color wheel. Thus, the clearest and purest colors of the light to be emitted are made possible. Furthermore, energy is saved since the power supply supplies the lighting device with a constant current and not with a constant voltage. Thus, voltage losses that can occur when the illumination device is supplied with a constant voltage are avoided, as a result of which the energy efficiency of the illumination device additionally increases.

The power supply unit preferably supplies the lighting device with a current intensity between 500 mA and 1000 mA, in particular with a current intensity of 700 mA.

In a preferred embodiment, the power supply unit supplies the illumination device with a constant frequency, in particular with a frequency of 4 kHz.

Preferably, the series circuits are driven within a defined repetition interval in the form of a sequence of 16 or 32 or generally (n * 16) equal time periods, where n ≥ 1. The greater the number of segments of the same length within the defined repetition interval, the greater the spectrum of light colors which can be imaged by means of the illumination device. In other words, the greater the number of equal length sections within the defined repeat interval, the greater the number of different feasible blends.

In a preferred embodiment, the structural component has one or more chips / s, on each of which a light-emitting diode of one of the three series circuits is arranged. Accordingly, at least one chip is preferably formed, on each of which a light-emitting diode from each one of the three series circuits is arranged. In particular, such a chip in each case has an LED which emits a light of one of the three primary colors red, green and blue. The arrangement of such chips enables a particularly simple installation of the illumination device. In particular, all the LEDs of the illumination device are arranged on such chips.

Preferably, at least one light-emitting diode has an electronic circuit assigned to the light-emitting diode, which is designed and suitable for detecting an interruption of the series connection behind the light-emitting diode in the forward direction of the light-emitting diode and firing the circuit behind the light-emitting diode by means of the electronic circuit. Such a circuit allows a reduction of the pure circuits according to the installation dimensions. Thus, the series circuits can be adapted to the requirements.

By arranging such an electronic circuit, by means of which an interruption of the series circuit is detected behind the light emitting diode and then bridged by the closing of the circuit, it is thus possible to cut off the light emitting diode band behind the light emitting diode, which is associated with the electronic circuit and by closing the circuit by means of the electronic circuit to restore the operational readiness of the shortened LED strip immediately.

Preferably, the electronic circuit is adapted to detect an interruption of the series connection immediately behind the light emitting diode in the forward direction of the light emitting diode and to close by means of the electronic circuit, the circuit in the forward direction of the light emitting diode immediately behind the light emitting diode.

The term immediate is a position behind the corresponding light-emitting diode, which is associated with the circuit and referred to before the next in the forward direction subsequent light-emitting diode.

This makes it possible to shorten the LED strip between these two LEDs, d. H. cut off, it being ensured on the basis of the light emitting diode before the section associated circuit that the light emitting diode band can be operated to cut further, as by means of the circuit of the separate circuit is immediately closed.

Furthermore, the invention relates to a patio roof or conservatory with such a structural component. By means of such a patio roof or winter garden, the lighting is provided in the area of the patio roof or winter garden in an energy-efficient and space-saving manner. Furthermore, it is possible to ensure the illumination by means of a light from a large color spectrum.

The structural component for installation in conservatories, patio roofs, vertical and horizontal shading can be used as a support, support posts, beams, eaves, Rafters, guide rail, housing are used in particular for horizontal or vertical or oblique installation.

In this case, three series circuits 3, 3 'and 3 "connected in parallel, namely a first series circuit 3 with the red light emitting LEDs LR1, LR2, LR3, LR4, LR5, a second series circuit 3' with the green light emitting LEDs LG1, LG2, LG3, LG4, LG5 and a third series circuit 3 "with the blue light-emitting LEDs LB1, LB2, LB3, LB4, LB5.

All of the three parallel connected series circuits 3, 3 'and 3 "are connected to the single power supply unit 2 and are supplied with a constant current from the power supply unit 6. The arrangement of only one power supply unit 2 saves installation space and costs, without Functional restrictions of the lighting device to have to accept.

Furthermore, all of the three series circuits 3, 3 'and 3 "connected in parallel are connected to the single multiplexing switch, which is designed as a demultiplexing switch 4. The demultiplexing switch 4 passes the pulse-width-modulated current signal of the power supply 2 to the respective series connection the predetermined Wiederholintervalls in the form of a sequence of equal periods of time such that within a single time period in each case a series circuit 3, 3 'or 3 "driven, ie is energized. Depending on the procurement of the given repetition interval, a light of a mixed color can be generated.

Furthermore, in FIG. 2 possible cutting lines 100, 200, 300, 400 drawn in order to shorten the series connections. Each of the light-emitting diodes LB1-LB4, LG1-LG4, LR1-LR4 is assigned an electronic circuit, by means of which the severance at one of the cut lines 100, 200, 300, 400 is detected and by switching over of the respective light-emitting diode LB1-LB4, LG1.

As a result, the series circuits are still controllable. The representation according to FIG. 2 is only schematic in nature and greatly simplified, since only the light emitting diodes LR1 - LR4 associated electronic circuits in the form of the transistors TR1 - TR4 and the ohmic resistors RR1 - RR4 are located. The other LEDs LB1 - LB4, LG1 - LG4 are each assigned identical electronic circuits, which are not shown for reasons of simplicity. As a result, the series connections can be shortened and the length can be adapted to the installation situation in the respective structural component.

In the Ratio column, the distribution between the colors R, G and B is given according to the configuration of the drive.

In the following Table 1, those of the respective configurations of the drive according to FIG FIG. 3 resulting light colors indicated. For a better overview, the configurations 2 - 8, 10 - 16, 18 - 24, 26 - 32 and 34 - 48 have been summarized as they each represent transition areas between two light colors. Line acc. Fig. 3 light color a Cold white b White c Warm white 1 red 2-8 Transition red-green 9 yellow 10-16 Transition red-green 17 green 18-24 Transition green-blue 25 cyan 26-32 Transition green-blue 33 blue 34-48 Transition blue-red

By means of the lines 1 to 48 after FIG. 3 specified drives of the individual series circuits are the different basic colors and furthermore different mixed colors on the color wheel representable.

By way of example, the configuration 9 according to line 9 of the left-hand column will be correspondingly described below FIG. 3 described to produce the light color yellow. This configuration requires according to FIG. 3 in that, within the defined repetition interval, the series circuit is driven for a total of eight time periods, has the red-emitting light-emitting diodes, and the series circuit, which has green-emitting light-emitting diodes, is driven in total for a total of eight time periods. It is irrelevant in which order the series connection with the red light-emitting LEDs for eight time periods long and the series connection with the green light emitting LEDs are driven for eight periods of time. Only the total number of time periods within the defined repetition interval during which the two series circuits are activated is significant for the color of the light which is perceived by the human eye. To maintain the light color, the repeat interval is always repeated as per configuration 9.

At a sufficiently short repetition interval, the human eye perceives a light of yellow color in the example described. In this case, the individual series circuits are not controlled simultaneously, but within a time interval one of the series circuits, so that the energy requirement of the lighting device is kept low. According to the in the FIG. 3 given control modes can be a total of 51 light colors and thus represent a large color spectrum of the light.

To produce the mixed colors, it is not the exact in Fig. 3 specified order of the control of the individual rows, but only to the ratio of the different primary colors within a Wiederholintervalls each other to produce the desired mixed color.
