Description

efficiency, service life, heat economy and also ignition time for a light source. However, a problem can arise in display applications due to the directional properties of the LED lights, large which can cause uneven light distribution on a lighting object, and / or can therefore also cause glare at such lighting objects, where a person working or otherwise staying under the lighting must look directly in the direction where the lighting with the help of an LED is strongest.

The problem also occurs with both light bulbs and gas-filled lamps. Furthermore, although indirect illumination used to avoid glare actually reduces glare, it also absorbs some of the radiation in a manner which depends on the structure and unevenness of the surface to be illuminated. , and has a lighting-reducing effect. At the time of the priority date of the present invention, the applicant is not aware of any generally known luminaire technology as such with which uniform lighting could be achieved in a controlled manner with high efficiency of the light source in connection with short ignition time of the light source.

Brief Description of the Invention The invention aims to solve or at least reduce the above-related problems in the prior art in order to achieve even lighting indoors and / or outdoors.

The objective is achieved with the help of a reactor in accordance with an independent patent claim that concerns a luminaire in accordance with an independent patent claim that concerns the luminaire. The invention relates to an additional luminaire in accordance with an independent patent claim concerning a luminaire. The invention relates to a further luminaire system in accordance with an independent patent claim concerning a luminaire system. The invention relates to an additional control program of an independent luminaire with respect to the luminaire's control program.

Advantageous embodiments of the invention are presented in dependent claims. Other advantageous embodiments of the invention have also been presented in examples as well as in the description with reference to urer gures. The design features of the invention can be combined to the appropriate extent. In a solution according to the invention, a correction of the direction pattern of a light source is used in such a way that in the directions in which a light source emits radiation more strongly in accordance with its radiation pattern, the light source radiation is reflected further away from the light source. than the directions in which radiation from the light source in accordance with its radiation pattern is weaker. This is accomplished by means of a reactor in accordance with an embodiment of the invention.

By advantageously using, for example, LEDs in a radiation source in a luminaire, to generate light with high efficiency, it is then possible to utilize the fairly strong directional dependence of an LED on the directional pattern even if the directional pattern was narrow. Designing a reactor in accordance with an embodiment of the invention is quite simple for LED-based luminaire solutions and thereby producing them is comparatively uncomplicated.

On the basis of embodiments based on inventive thinking, a person skilled in the art could also apply it to radiation sources with a complicated direction pattern, where on the other hand known ones have a lower efficiency. The design of a reactor would then possibly be more complicated, after which the installation accuracy should also be better than for a luminaire with an LED light source which uses a reactor in accordance with an embodiment of the invention. With the help of LEDs, a simple construction is achieved that is both strong and easy to install and maintain.

Especially in such embodiments of the invention, where LEDs are used as the light source, it is also possible to tone the color of the lighting by using a set of LEDs suitable for color tinting. According to an embodiment of the invention, it is then possible to make corrections to the color reproduction index.

By then using t.o.m. a few, for example, red LEDs, it is possible to significantly change the color rendering index for cold white LEDs. You can therefore correct the color reproduction index when using both outdoor and indoor luminaires. It is also possible, with the aid of the color of a protective glass, which at least partially protects a luminaire and a radiation source, to tone the color of the light of the annature, provided that losses in the protective glass as such do not adversely affect the lighting application. Since LEDs also withstand connection to and from in a completely different way than conventional lamps and fluorescent lamps, it is also possible to supply LEDs by letting their supply current pulsate at sufficiently high frequencies, even fl your kilohertz or even higher, whereby fl always in LEDs is not perceived by the human eye. At the same time as saving energy by influencing the duration of light in a certain segment of an LED by means of the pulse length, it is on the other hand also possible by means of pulsing to instantaneously balance a current source's load of a large set of LEDs. By segmenting the luminaire's LEDs into groups to illuminate at a certain pulse, while others do not illuminate, it is possible to adjust the light intensity as the output of light energy generated by a section is selected individually for the sections so that they are different for sections within the same group. of sections. According to an embodiment of the invention, it is also possible with the aid of LEDs to realize such luminaires which are connected to and / or disconnected according to the movements of people (also animals or machines). Then, for example, an entire street does not need to be illuminated throughout the dark period with full effect. As an example, it is possible to save electricity when a motion detector is used to control a luminaire according to an embodiment of the invention, which luminaire has a reactor in accordance with an embodiment of the invention optimized to utilize a radiation pattern corresponding to a set of LEDs to offer even lighting over an area to be illuminated, e.g. a street. To control the lighting in a sensible way, it is useful to use a control program in the control unit in the luminaire's luminaire system, whereby it is possible to use an individual sensor (or set of sensors) to control one or fl your luminaires to connect them, from and / or tone the color of a luminaire for the most advantageous use of a lighting system. With the help of settings in the control unit, it is also possible to maintain general lighting with low power, whereby a passer-by has an easier time identifying his way during a time of day that would otherwise be dark. By using street luminaires, it is then possible to maintain e.g. a light level of 20%, when no passers-by are present on the street, but, when a passer-by is detected by a motion detector, the light level around the passer-by can be raised at least to a higher level, if not to full effect. In suitable places, it is also possible to switch on / off certain luminaires to a certain brightness.

According to an advantageous embodiment of the invention, a radiation source has been arranged in a luminaire to be placed acid-metrically at the middle part of a radiation-dividing point E in the rectum. In accordance with an embodiment of the invention, the lighting can be increased around the edges of an illuminated area by means of additional parts in the transverse direction, but on the other hand a simpler design can be achieved by omitting additional parts. By using additional parts, however, it is also possible to improve the amount of lighting that reaches an illuminated area even if the effects of the radiation source have been reduced.

In the figures, measured values and dimensions are only illustrative examples and therefore do not limit the embodiments of the invention to only the values and / or dimensions in accordance with the mentioned examples. In the fi gures, the same reference numerals have to some extent been used unless otherwise stated. The references then do not necessarily have to be exactly the same, as a person skilled in the art realizes on the basis of the context of the illustrated embodiment.

Detailed Description of the Invention Figure 1 shows a reactor in accordance with an embodiment of the invention as consisting of at least a first section 101 and a second section 102 in direct contact with each other via a discontinuity point E for the curvature in the longitudinal direction AB. The example in the clock also shows curved side sections 10la, 101b, 102a and 102b in order to further equalize the distribution of the light emanating from a light source also in the transverse direction CD, FG. A reactor in accordance with the example of the guru can be manufactured by means of a method known per se, for example by pressing or by using molding by arranging the reactor material (for example plastic) in the mold of the example in fi gur 1 by means of a casting liner. , after which the bearded beard is removed as appropriate. A reactor can also be manufactured by forging and / or grinding or by otherwise forcing it into its shape. A method known per se, which is to be suitable for forming the material selected for the reactor, can then be used for the manufacture of a reactor in accordance with an embodiment of the invention. The numbers 680 and 780 are examples of measurements in millimeters without one being limited only to said measurements or their proportions.

According to Figure 1, a casting / pressing piece comprising a reactor according to an embodiment of the invention has an end 100 formed by a casting beard, and also other end sections 100a illustrating manufacture by means of a casting / pressing process. Although the casting in the example in Figure 1 is square, it is not desirable in the invention to be limited only to one embodiment in accordance with the example in the figure. According to one embodiment of the invention, the sections 100 and 100a of a reactor are removed in connection with the manufacture of a reactor. The edge edge of the flange 100 is indicated in the figure. A straight line de fi nied by its direction and another straight line ltks de fi nied by the edge de fi a plane (leps, ltks) whereby a plane in one direction at a right angle thereto, which runs through a straight line AB while intersecting a piece of reactor at the top of its first section 101 and its second section 102, it ier denies a longitudinal cross-section (AB) and a longitudinal double-curved profile having a similar shape and having a discontinuity point of the curvature at point E. The said point E is a ridge-like formation between said first 101 and second 102 sections. Point E appears to interrupt the curvature of the first section 101, but the shape of the rectifier continues to bend in the area of the second section 102 in accordance with its curvature. According to one embodiment of the invention, sections 101 and 102 are symmetrical with respect to point E, but it is not desirable that the invention be limited to this alone.

A straight line CD has also been plotted in Figure 1, through which a plane at right angles to a plane (leps, ltks) defines a transverse curvature of a first section 101 by means of a cross section through the rectum. Correspondingly, in Fig. 1 a straight line FG has been drawn at the position of the apex through which line a plane at right angles to a plane (leps, ltks) de . Although it is shown that the curvatures in the example in Figure 1 in the transverse direction are almost the same with the accuracy that the reading allows, it is not desirable that in the embodiments of the invention the limits are limited to the same curvatures, and the curvatures can be different, even very different. from each other to provide a different illumination of an area, which is illuminated by section 101, than by an area illuminated by section 102. Longitudinal curvatures of sections 101 and 102 need not be the same either, even though the example of fi guren so indicates. Although it is shown that a longitudinal curvature deviates from a transverse curvature for sections 101 and 102 in Figure 1, it is not desirable to limit the invention only to the example shown, and according to one embodiment of the invention these may be the same or almost the same. likadana.

The side sections 10a and 10b may, as appropriate, be pairwise symmetrical on either side of the first section 101 in the transverse direction CD. The side sections 102a and 102b may, as appropriate, be pairwise symmetrical on each side of the second section 102 in the transverse direction FG. According to one embodiment of the invention, there is a discontinuity point between the side section 10la, 101b and the section 101 (also correspondingly between the section 102 and the side section 102a, 102b). According to another embodiment of the invention, said discontinuity point is rounded and according to one of its variations has been made to blend into the curvatures of sections 101 and side sections 10la, 101b (corresponding also to section 102 and side sections 10a2a, 102b) to change the light distribution in correspondingly.

The curvatures of the side sections in the embodiments of the invention are not limited to those shown in Figure 1, and they may also be different to the extent applicable.

According to one embodiment of the invention, radiation sources can be installed at the point of discontinuity to generate illumination.

According to an embodiment of the invention, the longitudinal curvature in the longitudinal direction AB and / or the transverse curvature in the transverse direction CD, FG has one of the following shapes: the shape of a conical section, the shape of an exponential curve, the shape of a logarithmic curve, the shape of a progressive variable arc in which the curvature of the arc increases or decreases according to the position between the ends of the arc. The curvature as such is inversely proportional to the radius of curvature. According to one embodiment of the invention, the curvature in the longitudinal direction and / or the curvature in the transverse direction, and thereby the corresponding curve radii, are determined by the shape of the area to be illuminated, the radiation source directional pattern and the height of the plant.

According to an alternative embodiment of the invention, the first and second sections of the reector are collectively integrated in a common shape of a half torus in which the discontinuity point E forms a conformal tip which acts as a center of rotation, as a cross-sectional curve of the longitudinal (AB) profile rotates about a right line passing through a discontinuity point E and thereby forming a half torus. A reflector is then better suited as a component in luminaires, which are used for illumination of round areas, than a reflector according to Figure 1. A radiation source is then advantageously also rotationally symmetrical without, however, being limited only to this. A reactor, or a section thereof according to an embodiment of the invention, is made of a material comprising the reactor material, by means of a design method known per se to give a certain shape to a product of a thin material, the raw material thickness is significantly small compared to other dimensions. Thus, as applicable examples of embodiments, one can consider e.g. extrusion, injection molding and / or molding and vacuum forming to a suitable extent, as well as mechanical pressing against a mold, without being limited in itself to these or any combination thereof. In such embodiments it is meant that a material is thin when its material thickness according to one embodiment is less than 10%, but in another less than 5% and according to a third less than 1% of the longest dimension they fi denied by a plane in the reflector (leps , ltks) measured across the same.

According to one embodiment of the invention, a section of the reflector is coated with a light source which glows with a wavelength within visible light but which receives the required energy from radiation of shorter wavelength, which is emitted from a radiation source.

The coating can then be very thin to reduce losses and to maximize the net benefit of the lighting increase that can be achieved.

Figure 2 illustrates the use of a reflector according to an embodiment of the invention in a luminaire and at the same time the function of the reflector. A reactor with a longitudinal cutting profile taken in the direction of the straight line AB has been illustrated, the side sections being excluded from the illustration for the sake of simplicity. The first section 101 and the second section 102 of a reactor are connected at the discontinuity point E of the curvature below which (observed in the normal direction from which a curve is read) the radiation source 210 itself is located to generate illumination.

For example, a connection and mounting member 213 for attaching a radiation source to the mounting foot 214 may also include a control unit 400 and / or an energy source 402 with associated connections. An installation part may also contain a cooling device for the radiation source, for example a passive heating radiator or even a fan, which on the other hand consumes electricity. Although it is directly apparent from the dimensions in Figure 2 that the luminaire has a short foot in relation to the dimensions of the rectifier (suitable for, for example, the dimensions of a table lamp and / or floor lamp, but also for the dimensions of an outdoor lamp with a short foot), it is not desirable that the embodiment of the invention is limited only to dimensions in the example shown or to indoor luminaires. One skilled in the art will appreciate from what is shown in Figure 2 that the mounting foot 214 and the height h2 of the luminaire from the mounting base (ground surface / floor surface / other level, also including the wall of another embodiment) can be dimensioned to correspond to the dimensions of a street lamp.

As such, the dimensions of the mounting foot can be a known standard dimension that can be applied to the dimensions of an outdoor nature. In order to use the luminaire also elsewhere than indoors, the luminaire can be equipped in accordance with such an embodiment, which is to be used outdoors. According to one embodiment, a module, which consists of a reactor and a radiation source (in an embodiment with its cooling device), is equipped to be installed for both indoor and outdoor use. To the extent applicable, the equipment may be adapted to local standards according to the intended use. A luminaire in accordance with an embodiment of the invention can also be used as outdoor lighting, although nothing in itself prevents a luminaire according to an embodiment of the invention from being used as an indoor luminaire, even though the luminaire is equipped to be suitable for outdoor use. Suspension luminaire solutions are suitable, for example, for both indoor storage spaces and outdoor areas.

The radiation source 210 in fi gur 2 is at a distance hl from a discontinuity point E in the curvature (hereinafter also the point E).

The set illustrates a set of light beams, one of which is emitted in the direction of the arrow 212a and is reflected from the section 102, the arrow 212b, in the direction shown by the arrow, far away from the light source. An even illumination is then achieved by using a light source with a direction pattern according to fi figure 7, even though the light source is not ideal according to example 2. The direction 0 ° in fi figure 7 is indicated in the fi figure with a thin arrow. One of the light beams has been shown as directed in the direction of the arrow 2l, reflected from section 101 and continued in the direction illustrated by the arrow 211b in the vicinity of the light source. Some light rays have been drawn differently for sections 101 and 102 for illustrative purposes, but in practice the use of a radiation source with a symmetrical directional pattern (fi figure 7) creates an area of action, as a symmetrical curvature exists between the reactor sections in also symmetrical reflection and even lighting within armature. According to an embodiment of the invention, it is therefore possible, by choosing shapes of the reactor sections 101 and 102 so that their longitudinal curvatures are not symmetrical with respect to point E, to produce a different lighting distribution in the area of section 101. than in the area for section 102, which deviates from the relationship when the longitudinal curvatures were symmetrical with respect to point E. The point Ei in Figure 2 is a curve according to fi figure 1, at the point where sections 101 and 102 are joined.

Figures 3a-3f illustrate annaturations (300, 301, 302), according to an embodiment of the invention, containing a reactor according to an embodiment of the invention.

The figures also illustrate mounting variations for luminaires according to embodiments, to be placed on a wall, in a ceiling, on a floor / a street. According to a set of variations, a luminaire (300, 301, 302) has been manufactured to be mounted on a surface, while a luminaire (300, 301, 302) has been manufactured according to another set of variations to be fitted either completely or partially in applicable extent in a mounting base. In a set of embodiments, it may then be necessary to mechanically protect the reflector itself in the luminaire and / or the light source with a protective disc or in some cases even by casting the light source and the reflector in one piece as a luminaire module. A luminaire module can then be ready or for certain application purposes even somewhat diffuse or otherwise scattering. It is obvious to a person skilled in the art that connections should be provided for an energy source to be connected to the appropriate extent. According to an embodiment of the invention, a luminaire module can also be hollow to the applicable extent, and manufactured by means of a method known per se, other than casting.

Figure 3a illustrates a luminaire 300, according to an embodiment of the invention, with a radiation source 210 at a distance h1 from the point E between the reactor sections 101 and 102. For the sake of simplicity, no other parts of the luminaire have been shown. In the luminaire example, the luminaire is a hanging luminaire, which is arranged to be hung, for example, in a ceiling or in a wall bracket by means of a chain, a rod or a combination of the like. The lighting is intended to be displayed in the direction of the text "Figure Sa". Figure 3b shows a luminaire which otherwise resembles to the applicable extent the figure in Figure 3a, except that the illumination direction is opposite, in order to provide indirect illumination.

Figure 3c illustrates a recessed luminaire 301, which to the applicable extent otherwise resembles the luminaire 300 shown in Figure 3a, except that it is made to be mounted either recessed or as a surface mount. According to an embodiment of a luminaire 301, the mounting method can be selected when a mounting module has been made to enable either flush mounting or surface mounting. According to one embodiment of the invention, a mounting module comprises a reactor and a radiation source according to an embodiment of the invention to be attached thereto to provide a luminaire in accordance with an embodiment of the invention. Figure 3d illustrates a luminaire that is otherwise similar to that of Figure 3c, except that it has a luminaire 302 arranged for indirect illumination, a primary illumination direction from the radiation leaving the reflector being illustrated as directed away from the text Figure 3d.

Figure 3e illustrates a luminaire 300 intended to be mounted at the top of a post T, by means of a beam 01, 02. The luminaire 300 may be a luminaire intended to be mounted immovably at the beam 01 or intended to be mounted in suspended geometry at the beam 02 with using a bar, a spoon or a combination of these. Although the example in the har gure has two beams, it is not desirable in the embodiments of the invention to be limited to an example in accordance with only two beams, and the number of beams may instead in some other embodiments be one, three or even larger. While the beams have been drawn horizontally, or perpendicular to a post, it is not desirable that in the embodiments of the invention be limited only to a mutual placement of a beam and a post in accordance with an example. By selecting the height h3 so that it is suitable for the intended use, it is possible to achieve heights which are suitable for different embodiments in order to offer both indoor and outdoor lighting.

Figure 3f illustrates a type of luminaire intended for surface mounting on the ground, on a street and / or on a floor.

Although a luminaire in Figures 3a-3f is illustrated by marking it by means of a dashed line in accordance with an embodiment of the invention, it is also possible to illustrate the contour of a luminaire module with a dashed line without 10 15 20 25 30 13 is limited to a cross section in the form of a right-angled quadrilateral which is itself shown in accordance with the example.

Figure 4 illustrates an outdoor lighting to be realized by means of a luminaire according to an embodiment of the invention. A lighting system according to an embodiment of the invention has at least one luminaire 300 according to an embodiment of the invention. A street lamp with the luminaire 300, 301, 302 has been illustrated by means of a post T and an oblique beam O. A street lamp can also be of a type shown in Figure 2. Figure 4 has the mounting foot of the street lamp in a lighting system. according to an embodiment of the invention, a control unit 400 is connected to the post. Another arm mounting foot for a street lamp in a lighting system according to an embodiment of the invention has an energy source 402 connected to the pole. Arrows with dashed lines illustrate the control offered by a control unit for certain street lamps 300, 401. A street lamp 300C in fi gur 4 is color-toned using a set of colored LEDs to tone the color among a set of other LEDs in a radiation source. Similar color toning can also be used in indoor luminaires according to an embodiment of the invention. While Figure 4 illustrates an exemplary system, designed solely to show luminaires according to an embodiment of the invention, it is not desirable to exclude from the embodiments of the invention such lighting systems which also have conventional street lamps in addition to street lamps according to embodiments of the invention.

Figure 5 illustrates a control offered by a control unit 400, as well as a control unit construction. According to an embodiment of the invention, the control unit 400 has at least one connection for one of the following control devices: ~ a clock (501) arranged for time control, - a light sensor 502 arranged for control according to lighting, - a motion detector 503 arranged for motion-based control , - slave control equipment 504 for operating according to external control, - control output (505) for offering external control, - control input (507) for offering external control, 10 15 20 25 30 14 - a controller that controls the charging of an energy source control the energy source for a luminaire, - a maintenance port 506 for making changes to a software corresponding to the control criteria for a control unit 400, and - a transmitter / receiver equipment 508 for communicating control settings with certain other luminaires, for controlling light production according to ambient light levels .

According to an embodiment of the invention, a control unit comprises a set of control devices, which set comprises the devices for offering time control 511, the devices for providing light control 512, the devices for providing motion control and the devices for offering slave control according to external control.

A microprocessor uP controls the operation of the control unit by means of a control program stored in a memory, which the processor has access to and which can be updated via the maintenance port 506. According to an embodiment of the invention, the maintenance port can be controlled by means of the transmitter-receiver equipment 508. To the extent possible. these be wired or also wireless. A control unit can then be arranged to be updated by means of radio frequency transmission by utilizing radio frequencies according to a technique known per se for utilizing these. A number of control units can then be updated while others can selectively be kept updated. According to one embodiment of the invention, each control unit in a set of control units has been named digitally.

It is then also possible to utilize a digital signal in a manner known per se in order to update control units in a manner specific to individual control units in order to control at least one luminaire. The luminaires can also be named, after which a control unit can specify a specific luminaire and command it to be switched on / off according to the settings in a control program. The control output is an output for an output signal. The control input is an input for an incoming control signal. The control input has in the example been isolated from the slave control, because the control that the control output according to an embodiment offers is for example arranged to have a regional effect (for example in a district) and thus be in a sense general, after which each luminaire can be configured to offer light. to its own individual location, but at the same time taking into account deviations in nearby local circumstances for an annature on the basis of the sensors in its own 10 15 20 25 30 15 control unit. You can then also save electricity. In the example, on the other hand, the slave control switches the lamps controlled by the control unit to operate unconditionally in accordance with a slave control signal. I / O illustrates a control device, which regulates input and output signals in a control unit according to the functions of the microprocessor, for controlling the lighting and / or for updating the control unit. HIC illustrates a control device for switching voltages and / or currents in the strong current range in accordance with the needs of the luminaires. The components of the control unit can be integrated to the appropriate extent. At least some of the control unit components may include programmed components.

An energy source in a luminaire according to an embodiment of the invention is illustrated in Figure 6. The luminaire then contains an energy source 402 connected thereto which comprises at least one of the following: - an accumulator 601, - a solar cell 602, - a fuel cell 603, - a wind generator 604 , - a mains connection 605, - one of those mentioned in a combination to generate lighting.

It is then possible, by using LEDs as radiation sources, to provide lighting in order to achieve high efficiency, whereby even a solar cell is in some cases suitable to be used as an energy source for charging accumulators at times when the luminaire is disconnected. In particular, if a surface of a reflector could be made of solar cell material, one could then use a reflector surface which is intended to be non-reflective in luminaires which illuminate in one direction, but not to the same extent in double luminaires with two opposite luminaires 300 intended to illuminate in opposite directions. In some cases it may also be possible to use wind to power a generator and thereby charge the accumulators in a street lamp during the day. A fuel cell can also be useful in certain special situations for generating electricity according to one embodiment. For example, a fuel cell and / or a generator set, which comprises an explosion engine, may be advantageous as a reserve energy source in the event of a power failure, to illuminate objects with a critical need for lighting in applicable luminaires. An energy source according to an embodiment can also be a conventional mains line or a three-phase line, but also another electrical line specially designed for LEDs.

Figure 7 illustrates a symmetrical light distribution curve for a radiation source.

Figure 8 illustrates a radiation source 210 applicable to an embodiment of the invention. It has a radiation source 210 as an example, with LEDs 803, 805.

LED 803 is a colored LED to achieve color toning. According to one embodiment of the invention, all LEDs in a section of a radiation source are the same within the limits of a certain manufacturing tolerance. According to one embodiment of the invention, a radiation source has only one section, but according to another embodiment, there are at least two or two. The set of 804 colored LEDs 803 is illustrated by a dashed line. If necessary, the set can be controlled by means of a control device in a control unit, per se independent of other LEDs and / or the sections they form.

The LED sections 801 and 802 can likewise be switched on or off according to control provided by a control device in the control unit. It is not desirable that the amount of radiation sources and / or LED sections be limited solely in accordance with the example shown, nor the placement of individual LEDs relative to each other or within a section, nor that the shape of the LED set be solely in accordance with the example shown. A set of LEDs can also be rotationally symmetrical. According to one embodiment, LEDs in a functional section can be distributed as sections of other, different sections, for example in connection with color toning. According to one embodiment, some sections may be slightly spaced apart. According to one embodiment, LEDs in a section have been distributed in a random or semi-arbitrary manner in a set of LEDs. According to an embodiment of the invention, a set of LEDs in a luminaire has been divided into sections. According to an embodiment of the invention, the sections can be the same size, classified according to the number of LEDs or according to power, but also be arranged to generate different brightnesses with a luminaire, as some sections are supplied with electricity to generate light energy with a luminaire according to settings in a control unit. 10 15 20 25 30 17 Example 1 A luminaire according to an embodiment of the invention is arranged as a street lamp. With the aid of a control unit it is then possible to intentionally connect a radiation source 210 to and from even a frequency of one kilohertz, whereby the human eye does not notice fl always in the light. Pulse length and / or distance to the following pulse, the work cycle, can be adjusted to suit. The pulses can also be directed to certain sections of a radiation source by means of control emitted by a control unit. With a pulsed current source to generate lighting, it is possible to use different LED sections in a radiation source in turn, whereby the effect of individual LEDs with impaired function is evened out, even though this is also otherwise insignificant. At the same time, it is possible to balance differences between LEDs. The electricity consumption and the instantaneous load on the power source can then also be made to approach the average value.

Not all LEDs are needed in summer for lighting, even if they are needed during the winter. On the basis of a signal emitted by a light sensor, it is possible to measure the brightness and adjust the lighting accordingly by means of control. With the help of a clock in a control unit for a luminaire in a luminaire system, it is possible to adjust in such a way that lighting is switched on for a certain time, for example in winter in Helsinki from 15:00 to 9:00, but during in summer, the lighting is instead switched on from 23:30 to 3:30. Correspondingly, north of the Arctic Circle in Rovaniemi there is no need for lighting at night during a certain period in the summer, while in winter it is possible to switch the lighting on during the day at a brightness suitable for the dark time period in the polar region. This can be achieved when, with the aid of the clock in the control unit, a suitable calendar function has also been realized, but also by using a certain lighting limit value for the light sensor below which the lighting is switched on, but above which it is not. You can even use gräns your limit values according to an embodiment to provide lighting in fl your steps. A set of criteria for the realization of lighting can be arranged with the aid of logical conditions in successive gates, whereby only a combination that meets all the conditions gives a command in the control unit that makes the annature shine. According to one embodiment, a motion detector has been arranged to observe movement of an object of at least a small pedestrian size in the detection zone of the detector and to emit a control signal to the control unit, which switches on a section of the radiation source in a street lamp luminaire if i) is the right time of day, ii) is the right lighting for the surroundings, iii) is the right time of year and / or (iv) is there sufficient available supply current in the luminaire's power source. A luminaire can then be left switched on for a certain period of time with the help of a timer. A control unit can then also offer control to other nearby street lights that will be switched on when a pedestrian passes. You can identify a pedestrian's direction of movement with the help of motion detectors and you can then disconnect unnecessary street lights in the direction of arrival after a certain predetermined time, provided that the motion detector does not detect other movement in the area.

You can then save electricity, especially during times when few people are moving, ie. from evening to early morning. Since a street lamp according to an embodiment of the invention has a luminaire according to an embodiment of the invention, and in it a reflector according to an embodiment of the invention, even lighting of the street is provided during the time the pedestrian needs, and since a radiation source for a luminaire has a set of LEDs, these work immediately and achieve full brightness in a fraction of a second. Connecting individual LEDs to and from sections can be controlled in the control unit through which a street lamp is controlled. The color of the lighting can be tinted and you can even change the tinting with the help of a single luminaire.

Color tinting can be particularly beneficial indoors, for example, to create atmosphere through the lighting.

According to one embodiment of the invention, the movement of a person walking on a street is predicted by means of a control unit in a lighting system which regulates luminaires to a higher light level in an estimated direction of travel.

Although a street lamp is described above as an example among the embodiments of the invention, the example can also be used in indoor luminaires to the applicable extent. Especially also in pet and warehouse buildings. But also in alarm equipment and systems, which switch lighting on and / or off. 10 15 20 25 30 19 In some situations, a conventional street lamp fitted with a gas-filled lamp would not even have time to switch on properly before it should already be switched off / regulated to a certain light level after a pedestrian has already passed. A conventional street lamp would also suffer from recurring connection and disconnection operations and its lamp would be kept in working order for a much shorter time than those used continuously on, while an LED-based radiation source simply endures being continuously switched on and off by a great deal. better and does not need a special igniter. In addition, the lighting from a luminaire according to an embodiment of the invention can be made more uniform than by using a conventional street lamp in its lighting area.

Example 2 A radiation source in a luminaire according to an embodiment of the invention is in an ideal case almost point-like, whereby it is possible to divide light from the position of the point E by a symmetrical reflector according to an embodiment of the invention to each point in the area to be illuminated. , which in itself can be achieved. A luminaire according to an embodiment of the invention is then operated to illuminate an area where all the points of the area receive light from the light source in the luminaire, whereby the influence of individual LEDs is equalized within the lighting for the area. Color toning with the help of colored light sources is then also directed at an entire area which is thereby illuminated with colored light without having deviated spots or arms deviating to a harmful extent caused by dense light sources in an illuminated area. An ideal case according to an embodiment of the invention can in practice almost be achieved by using a suitable radiation source with symmetry around the point E in its radiation distribution. The symmetry may be mirror symmetry, but, especially in an alternative embodiment, also rotational symmetry without being limited only to said embodiments as such. According to an embodiment of the invention, it is then possible to place sections and / or parts of them in the geometry of the radiation source in such a way that conditions within the illuminated area can be achieved with sufficient accuracy in accordance with an ideal case.

Color toning can then be realized with such sufficient accuracy that the human eye does not perceive that the color toning would cause an area illuminated by a light source to be perceived as deviating in color from other sections in the same area. On the other hand, it is also possible in some embodiments to use an asymmetric radiation source to influence the emphasis of the color tone in certain parts of an illuminated area, as the division into sections and the placement of colored light sources in it are made correspondingly. The position of the sections can thus be used to achieve modifiable lighting to a certain extent.

According to an alternative embodiment of the invention, the curvature of a first section is different from the curvature of a second section of the rectum. One can then in the sub-sections of an illuminated area, which receives its light mainly from either the first or the second section, provide lighting which in itself has different light levels. Local uniformity in the illumination of the illuminated area and / or in parts thereof can be further affected by a coating of the reflecting surface of a reflector. By leaving certain parts of a surface of a reflecting section of a reactor uncoated, or by otherwise treating them so that they react differently, it is then possible to bring about variations to some extent in the illuminated area of a reflector. luminaires that use such a reactor. According to an embodiment of the invention, it is also possible to influence the shape of an illuminated area with the shape of appended sections, whereby it is also possible, by using additional components symmetrically in transverse directions, to create a symmetrically illuminated area, but by changing the symmetry and / or omit certain additional parts, it is also possible to correspondingly affect the symmetry of an illuminated area.

It is obvious to those skilled in the art that the basic idea of the invention can be realized in many different ways as the technology develops. Thus, the invention and its embodiments are not limited to the examples described above and they may vary within the scope of the claims.
