Description

SIGHT FOR LIGHTING DEVICE

FIELD OF THE INVENTION

The present invention relates to sighting devices intended to be mounted on a lighting device. Particular embodiments relate to a sighting device with compensatory effect with respect to its positioning on the lighting apparatus.

BACKGROUND OF THE INVENTION

Lighting fixtures are an essential part of the urban landscape and illuminate particular areas on vertical or horizontal surfaces. The accuracy of the arrangement of these lighting fixtures is particularly important for highlighting certain public events, such as concerts and sporting or artistic events. However, it is generally noted that it is difficult to position the lighting fixture accurately because the aiming device, which must be mounted on the lighting fixture, introduces orientation errors.

There are several solutions to facilitate the orientation of lighting fixtures. These can however have several drawbacks, for example having to be incorporated into the lighting fixture or by introducing inaccuracies which will have to be compensated for in a subsequent step. At the present time, we are not aware of any aiming device having a compensatory function with regard to their placement on the lighting apparatus by the application of an angular correction, while that would provide a more reliable and easier way to orient the light fixture. In addition, this type of aiming device should be adaptable to the different types of lighting equipment used in demonstrations and should be able to be used repeatedly. To compensate for the installation, an adjustment means should be provided. There is therefore a need for an aiming device intended to be mounted on a lighting device and having a compensating function having these characteristics.

ABSTRACT

The objective of the embodiments of the invention is to provide a sighting device having greater accuracy in use and allowing rapid and easy orientation of the lighting apparatus. More particularly, embodiments of the invention aim to offer a sighting device allowing a simplified orientation of the lighting apparatus.

BE2017 / 5825

According to a first aspect of the invention, an aiming device is proposed. The sighting device intended to be mounted on a lighting device comprises:

- a base designed to be placed on one side of the lighting device, so that the aiming device is retained on the lighting device,

- a pivotally coupled support to a first part of the base,

an adjustment means designed to adjust the angular position of the support with respect to said first part of the base,

- a shooting device provided on the support, and

- a communication module coupled to the shooting device and designed to communicate data, captured by the shooting device, to a display device.

The embodiments of the invention are based inter alia on the notion that a frequent error in the orientation of a lighting apparatus using a sighting device consists in first of all orienting the aiming in a direction parallel to an axis perpendicular to a light emitting side of the lighting device, which can lead to a discrepancy between the orientation of the aiming device and the orientation of the lighting device. By providing a support pivotally coupled to a first part of a base and an adjustment means designed to adjust the angular position of the support relative to said first part of the base, the difference in angle of view can be compensated for by so that the displayed image data corresponds to the orientation of the lighting apparatus in the desired position, thus providing high precision.

By means of the communication module, the shooting device supplies image data to a viewing device in the direction towards which the aiming device is oriented; and this allows a user to easily adjust the orientation of the lighting fixture based on image data received by the display device, for quick and simple positioning of the lighting fixture. The data viewed on the viewing device can be raw image data captured by the camera and / or transformed image data derived from the raw image data and providing additional information, e.g. ex. angular position, distance, visual aids. The display of this transformed image data on the display device further facilitates the orientation process. The base is preferably configured to allow stable positioning of the aiming device on the lighting device to reinforce the precision of the aiming device.

According to an exemplary embodiment, the base is substantially U-shaped, and this substantially U-shaped base comprises, in addition to the first part, a second part opposite to the first part, and a third part connecting the first and the second. part.

BE2017 / 5825

Due to its substantially U-shape, the base is quick to install on one side of the lighting fixture. The U-shape facilitates the introduction and retention of the aiming device on the side of the lighting fixture by naturally preventing excessive lateral movements of the aiming device; in fact, the first part fits into the front face of the lighting fixture, and the second part into the rear face of the lighting fixture. The U-shaped base can be installed on an upper, lower or lateral side of the lighting fixture, preferably centered in relation to the chosen side.

Centering the aiming device by aligning the aiming device substantially orthogonal to an optical center of the light fixture improves the accuracy of the aiming device. In another exemplary embodiment, the aiming device can be placed away from the center of the chosen side of the lighting device and can optionally include an additional adjustment means to further compensate for the position of the aiming device so as to be able to adjust the angular position of the support relative to the base with regard to two different angular parameters.

According to a preferred embodiment, the adjustment means comprises:

a mobile part mounted between the support and the base and capable of assuming a plurality of different positions corresponding to the different angular positions of the support relative to the base, and

- A coupling means designed to hold the support against the mobile part in the different positions of the mobile part.

In this way, the adjustment made using the adjustment means is more exact in its definition of an angular position. Indeed, a movable means mounted between the support and the base allows progressive adjustment of the angular position of the support relative to the base. In an exemplary embodiment, the movable means can push the support to increase the angular position.

However, for the mobile means to be effective, a coupling means must be provided to keep the mobile part in contact with the support or the base. In addition, the coupling means makes it possible to increase or reduce the separation between the support and the base so that, associated with the pivoting coupling of the support and the base, it defines an angular modification.

According to an exemplary embodiment, the mobile part and / or the coupling means comprise a curved part in contact with the support or the base.

BE2017 / 5825

This allows a less discontinuous adjustment of the angular position of the support relative to the base. Indeed, a curved part of the movable part and / or of the coupling means creates a better transition between the plurality of different positions to ensure a more fluid contact point. In addition, due to the continuity of the contact, the steps existing between at least two of the different positions among the plurality of different positions can be reduced to infinitesimal small.

According to a preferred embodiment, the adjustment means further comprises an actuation means making it possible to actuate the mobile part so as to be able to change the surface in contact with the curved part.

This allows adjustment of the adjustment means which is simpler and more accessible to a user by means of the manipulation of an actuating means.

According to an exemplary embodiment, the actuating means comprises a wheel.

This gives rise to an actuating means which is more practical to handle.

According to a preferred embodiment, the actuating means comprises a substantially angular scale to indicate the angular position of the support relative to the base.

The angular position can thus be adjusted more reliably. In addition, the addition of an angular scale allows more precise positioning of the actuating means and can be more easily associated with the desired position of the lighting apparatus and with the position of the aiming device present on the lighting fixture.

According to an exemplary embodiment, the mobile part is fixed to the support or to the base by means of a screw.

Thus, the movable part can change position continuously, under the effect of a screwing or unscrewing, which gives rise to a continuous change in the angular position of the support relative to the base. This allows for greater accuracy angular compensation.

According to a preferred embodiment, the actuating means is arranged so that it can rotate the screw.

BE2017 / 5825

The actuating means thus has a direct action on the mobile part.

According to an exemplary embodiment, the aiming device further comprises a support means provided on the base, said support means being designed to support the display device.

In this way, a display device can be supported on the base of the sighting device and increases the freedom of use of the sighting device for the user.

According to a preferred embodiment, the support means comprises a mount designed to receive the display device, such as a smartphone, a tablet or any other display device.

The display device is thus retained more securely, in particular in the case of a smartphone or a tablet. In other embodiments, the display device can be worn by the operator. The display device can be a “wearable” type device, eg. ex. a connected watch or connected glasses.

According to an exemplary embodiment, the aiming device further comprises a clamping means intended to clamp the base on the lighting apparatus.

In this way, the base can be held more securely on the side of the lighting fixture, by applying additional pressure to the lighting fixture.

According to a preferred embodiment, the tightening means comprises a bolt having a first end acting as a support leg exerting pressure against the lighting apparatus and a second end having a head capable of being turned by a user, said user bolt cooperating with a hole present in the second part of the base.

Thus, the clamping means is more easily usable and offers a reliable and simple means for retaining the aiming device.

According to an exemplary embodiment, the first and / or second part of the base are pivotally coupled to the third part, and the third part of the base can be extendable.

BE2017 / 5825

In this way, the base can be adapted and more easily fixed to a wide variety of shapes and dimensions on the side of the luminaire.

Those skilled in the art will understand that the technical considerations and advantages relating to the embodiments of the lighting apparatus also apply, mutatis mutandis, to the embodiments of a corresponding method described below.

According to a preferred embodiment, a method is proposed making it possible to orient a lighting device using a sighting device comprising a shooting device. This process includes the following steps:

- adjustment of the sighting device in order to compensate for a difference existing between a first optical axis of the shooting device and a second axis perpendicular to a light emitting side of the lighting apparatus,

- mounting the aiming device on one side of the lighting device, so that the aiming device is retained on the lighting device,

- capture of image data and display of data arising from the image data captured on a display device, and

- adjustment of the orientation of the lighting device as a function of the data displayed on the display device.

For quick mounting, a sighting device is placed on one side of a lighting fixture. Due to this mounting position, the first optical axis of the shooting device does not correspond to the second axis associated with the lighting fixture. The second axis associated with the lighting fixture may be an axis perpendicular to a light emitting side of the lighting fixture, or may be the optical axis of the lighting fixture. Depending on the separation between the first and second axes, and the distance from the area to be illuminated by the lighting device and aimed by the aiming device, a compensation angle will be set on the sighting device to allow greater accuracy. Once this is adjusted, the sighting device can be mounted. It will be noted that the order of the first two stages of this process can be reversed, but that the adjustment of the sighting device can be carried out before mounting for practical reasons. The mounting can preferably be carried out in a substantially centered manner with respect to the side chosen, for a more rigorous aim. In another exemplary embodiment, the mounting can be carried out in an offset manner relative to the chosen side of the lighting apparatus and the adjustment of the aiming device can optionally include an adjustment of the compensation angle according to two angular parameters to further improve aiming accuracy. After editing, image data

BE2017 / 5825 will be captured and displayed on a display device to easily assess the situation of the effective aiming direction of the aiming device. The displayed data can be raw image data as it was captured or transformed image data in order to be more easily usable. The orientation of the light fixture will be adjusted so that the displayed image data matches the desired position of the light fixture.

According to an exemplary embodiment, the method further comprises:

- removal of the sighting device from the lighting device.

In this way, the sighting device can be reused. In other embodiments, multiple viewing devices and / or aiming devices can be used at the same time.

Figure 4 shows a side view of another embodiment of the sighting device according to the present invention. The sighting device 100 comprises a U-shaped base 110, a shooting device 140 and a communication module 150. The communication module 150 is coupled to the shooting device 140 with a wireless or wired connection, and is adapted to communicate image data captured by the shooting device 140 to a viewing device (not shown). The display device is viewed by a user and can be a computer device.

The base 110 makes it possible to place the sighting device on one side 210 of a lighting device 200 and to retain it on the lighting device 200. The U-shaped base 110 can be installed on an upper side, lower or lateral of the lighting fixture 200, preferably centered relative to the chosen side, being centered on the upper side 210 of the lighting fixture 200 in the exemplary embodiment of Figure 4. The centering of the aiming device 100 carried out by aligning the aiming device 100 in a manner substantially orthogonal with respect to an optical center of the lighting apparatus 200 improves the accuracy of the aiming device 100. In another exemplary embodiment , the sighting device 100 may be disposed at a certain distance from the center of the chosen side of the lighting apparatus 200 and may include an additional adjustment means designed to compensate even more for the p osition of the sighting device 100 so that the angular position of the support 120 relative to the base 110 can be adjusted with respect to two different angular parameters.

The lighting fixture 200 emits light in a direction parallel to the optical axis of the lighting fixture 200. The light emitted is projected onto a surface 300, eg. ex. sports field. The imaging device 140 captures image data in a direction parallel to a first optical axis 303 of the imaging device 140.

It is possible that the lighting device 200 must illuminate a specific area of the surface 300. A sighting point 302 associated with the area to be lit can be visually marked on the surface 300. It may be desirable for the sighting point 302 corresponds to a second position 304a of a second axis 304 associated with the lighting fixture 200 when the latter is projected onto the surface 300. The aiming point 302 can correspond to a desired orientation of the lighting fixture lighting 200. The second axis 304 associated with the lighting device 200 may be an axis crossing the center of a light emitting side of the lighting device 200 and perpendicular to said light emitting side. The second axis 304 can also be the optical axis of the lighting device 200.

BE2017 / 5825

The role of the aiming device 100 is to orient the second projection position 304a of the second axis 304 on the aiming point 302 while taking into account the angular correction necessary to compensate for the positioning of the aiming device 100 on the side 210 of the lighting fixture.

The aiming of the aiming device 100 is deemed satisfactory if a first projection position 303a of the first optical axis 303 of the shooting device 140 is within a predetermined radius of the aiming point 302 when it seeks to correspond to the second position projection 304a of the second axis 304.

Figure 5 is a schematic illustration of an exemplary embodiment of a method for orienting a lighting apparatus using an aiming device according to the present invention. The method 50 includes adjusting the aiming device 51, mounting the aiming device 52, capturing image data 53, displaying the image data 54, adjusting the orientation of the camera. lighting 55 and possibly the removal of the sighting device 56.

The sighting device 100 includes a shooting device 140. It is possible that the position of the lighting apparatus 200 must be adjusted in order to be located in a desired position, so as to be able to illuminate a specific area of a surface 300 using the lighting device 200. The specific area targeted by the aiming device 100 can be visually marked so that an axis 304 perpendicular to a light emitting side of the lighting 200 and passing through the center of said light emitting side, when it is projected onto the illuminated surface 300, corresponds to the center of the specific area at the desired position, ie. a sighting point 302.

The aiming device 100 can be used to orient the lighting device 200 on this specific area. The aiming device 100 can be mounted on one side 210 of the lighting apparatus 200. The aiming device 100 can be mounted on an upper side, a lower side or a lateral side. The capture device 140 captures image data (see step 53 of FIG. 5). However, the optical axis 303 of the shooting device 140 does not correspond to the axis 304 associated with the lighting device 200 due to its mounting position. To compensate for the difference between the two axes 303, 304, a prior adjustment of the aiming device (step 51 in Figure 5) can be undertaken.

The distance between the two optical axes 303, 304 at their respective point of origin, the distance separating the aiming point 302 and the camera 140, and the distance separating the aiming point 302 and the camera lighting 200 define an angle between the two axes 303, 304, so that the two axes 303, 304 meet at the aiming point 302. The defined angle is corrected on the aiming device (see step 51 in Figure 5).

BE2017 / 5825

The aiming device is mounted (see step 52 in Figure 5) on the lighting device 200. A U-shaped base 110 included in the aiming device 100 allows the aiming device 100 to be retained on the side 210 of the lighting device 200. It will be noted that the steps of adjusting the aiming device 51 and mounting the aiming device 52 can be reversed. The shooting device 140 provided on the aiming device 100 captures image data facing the aiming device 100. However, given the angular difference existing between the optical axis 303 of the aiming device and the axis 304 associated with the lighting fixture, the image data may only partially cover the area targeted by the lighting fixture 200 when the lighting fixture 200 is not in the desired position.

The image data is transferred to a display device in order to be displayed (see step 54 in Figure 5), via a communication module 150 coupled to the shooting device 140. A user view the displayed image data (see step 54). The display device can consist of a tablet, a smartphone or a screen connected, via the communication module 150, to the shooting device 140. The display device can be mounted on the base 110 of the sighting device 100 , p. ex. using a mount, so that the sighting device 100 is simple to operate. The displayed data may consist of raw image data as it has been captured or transformed image data providing additional information to the user, eg. ex. angular position, distance, modified visualization.

The orientation of the lighting fixture 200 is adjusted according to the image displayed (see step 55). If the aiming device (step 51 in Figure 5) is adjusted within accepted tolerances, the lighting device (step 55 in Figure 5) can be adjusted by adjusting the orientation of the lighting fixture so that the displayed image is aimed at aiming point 302.

The lighting fixture setting (step 55 in Figure 5) is deemed satisfactory if a first projection position 303a of the optical axis 303 of the shooting device and a second projection position 304a of the axis associated with the lighting apparatus on the surface 300 are located within a predetermined distance according to tolerances of lighting intensity.

The aiming device 100 can be removed 56 before being reused to orient another lighting device 200.
