Description
COMPUTER-IMPLEMENTED METHOD FOR DESIGNING AN OPTICAL UNIT FOR A
LUMINAIRE, AND ASSOCIATED PRODUCTION METHOD
The present invention relates to a computer-implemented method for designing an optical unit for a laminaire, a computer program and system therefor, as well as an associated production method for producing said optical unit.
Methods to design optical unit are readily available and typically comprise the filling out of an extensive list of parameters, optical and geometrical parameters for example. in order to determine the best suited theoretical design of the optical unit for a given lighting site. The list of parameters is usually provided manually by a user of a computer-implemented method using a database of all existing luminaires/optical units. These parameters reflect the optical considerations and the installation possibilities of the lighting site. The user can then iteratively play with the parameters to find out which existing optical unit would best fit his needs. Obtaining such an optical unit design is a time-consuming operation and the computer-implemented method is typically not user- friendly for the non-initiated user. Also, depending on the lighting site, none of the existing optical units may be suitable for the intended use, leading to the expensive design of a complete new optical unit.
The object of embodiments of the invention is to provide a computer-implemented method allowing for a cost-effective design and a modulable optical unit for a luminaire.
According to an aspect of the invention, there is provided a computer-implemented method for designing an optical unit for a luminaire. The optical unit comprises one or more optical matrices.
An optical matrix comprises one or more optical elements. The method comprises the steps of: - receiving data related to a desired light distribution for the optical unit, - providing a database comprising a plurality of optical matrix models, each optical matrix model being associated with an optical matrix and comprising at least one light distribution of that optical matrix for at least one predetermined orientation, and an indication of further possible orientations, - using the database and the received data, determining at least one set of one or more optical matrix models amongst the plurality of optical matrix models for designing the optical unit.
By using a database of optical matrix models, the design of an optical unit for the desired light distribution can be determined at the level of the optical matrices, which improves the overall modularity of the optical unit. The use of a database of optical matrix models taking into account the orientations of the optical matrices increases the number of potential light distributions to be obtained with existing optical matrices, offering thus more possibilities of design. In this way, costs associated with designing an optical unit can be reduced by reusing existing optical matrices but rearranged as new sets. This allows optical matrices to be used for a wider range of applications. Alternatively, for a given application, the cheapest luminaire with an adequate set of one or more optical matrices may be determined. When using the database and the received data, at least one set of one or more optical matrix models amongst the plurality of matrix models may be determined which may meet or approach the desired light distribution.
The optical matrices may be regarded as the building blocks available for building the optical properties of an optical unit. An optical matrix may comprise one or more optical elements and may be regarded as a physical sub-element of an optical unit.
According to a preferred embodiment, determining at least one set of one or more optical matrix models. comprises selecting for each set one or more optical matrix models, and determining for each selected optical matrix model how many optical matrix models need to be included in said set. In this way, sets of different optical matrix models may be determined. By mixing different optical matrix models, a large variety of light distributions can be achieved, increasing thus the modularity of the design.
According to a preferred embodiment, determining at least one set of one or more optical matrix models comprises: - determining a plurality of sets of one or more optical matrix models from the plurality of optical matrix models of the database, - simulating the optical behavior of said plurality of sets of one or more optical matrix models, - selecting at least one set which simulated behavior meets the data related to the desired light distribution with a predetermined tolerance.
In this way, the method performs calculations for multiple sets of optical matrix models in parallel, avoiding the burden of an iterative process, increasing thus the user-friendliness of the design. By simulating the optical behavior is meant producing a computer model of the optical behavior.
When the simulated behavior meets the data related to the desired light distribution with a predetermined tolerance, it means that the computer model calculated approaches a model associated with the desired light distribution on at least one criteria with said predetermined tolerance.
According to a preferred embodiment, the method further comprises receiving a number of optical elements to be used in the optical unit. The number of optical elements to be used in the optical unit is a physical constraint, which may be related among others to a type of luminaire, or a size of a luminaire housing. It is noted that the number of optical elements to be used in the optical unit may be the same as the number of light sources, for instance Leds, used in the the luminaire or may be different in cases where multiple sources, for instances Leds of different colors or color temperatures, are arranged under an optical element.
According to a preferred embodiment, determining a plurality of sets of optical matrix models from the plurality of optical matrix models of the database comprises determining all possible sets of one or more optical matrix models matching the received number of optical elements in the optical unit. In this way, the user may limit the possible sets of optical matrix models to meet the physical constraints of the number of optical elements to be used.
According to a preferred embodiment, selecting at least one set of optical matrix models meeting the data related to the desired light distribution with a predetermined tolerance comprises: - ranking the possible sets of one or more optical matrix models according to a flux associated with each set and derived from each simulation, - selecting among the ranked sets the set of one or more optical matrix models with the lowest flux.
By flux associated with a set is meant the minimum light flux necessary to match the data related to the desired light distribution using that set of one or more optical matrix models. In this way, the most efficient set of optical matrix models can be retrieved, to further improve the reduction of costs when designing a luminaire for a given application. Additionally using the flux as criteria for optimization helps reducing the number of solutions presented to a user to improve his experience.
It is noted that a flux is measured in lumen, while a light distribution is measured in candela lumen. In practice an optical matrix model comprises a light distribution associated with an optical matrix and one orientation of that optical matrix. When simulating the behavior of a set of one or more optical matrix models, a theoretical light distribution for that set may be obtained based on the database of optical matrix models, from which a minimum light flux for that set may be derived in order to match the received data related to the desired light distribution. For instance for a set of asingle optical matrix, the light distribution of that set is equivalent to the light distribution of the single optical matrix. When the data related to the desired light distribution is for instance an illuminance of a lighting norm (in candela per square meters) and at least one installation characteristic of a lighting site (related to physical dimension in meters for instance), a minimum flux (in lumen) necessary with the light distribution (in candela/lumen) of that single optical to match this data can be derived.
According to a preferred embodiment, the method further comprises, using the database and the received data, determining orientations of the one or more optical matrix models of the at least one set of one or more optical matrix models. In this way, a set of optical matrix models with each its respective orientation can be determined, to further increase the modularity of the design.
According to a preferred embodiment, determining orientations of one or more optical matrix model of the least one set comprises determining a rotation around a first axis and/or a tilt around a second axis different form the first axis of each optical matrix model. Alternatively, determining the orientations of the matrix models of the least one set may comprise determining the relative positions of the matrix models with respect to each other. In this way, the orientation of each optical matrix model may be taken into account when designing the optical unit.
According to a preferred embodiment, receiving data related to a desired light distribution for the optical unit comprises receiving any one or more of the following: at least one luminaire installation characteristic, a lighting regulation, a desired light distribution. A lighting site may be characterized by installation characteristics and/or lighting norms. A lighting norm may contain normative values for illuminance, uniformity, glaring index among oters. From these parameters, a desired light distribution may be derived. The desired light distribution may represent the desired light distribution on the ground in the vicinity of the luminaire and/or the desired 3D light distribution of the luminaire around the luminaire. A desired light distribution can be a theoretical value originated from photometry studies or it can be the measured light distribution of an existing luminaire to be used as reference
According to a preferred embodiment, the luminaire installation characteristic comprises any one or more of the following: a pathway width, an interval distance between two neighboring luminaire base supports, a pathway surface material, pathway surface optical properties, a height of a luminaire head of the at least one luminaire, a number of lanes of the pathway, one or more circulation directions of the pathway, a lateral distance between the pathway and the at least one luminaire base support, a lateral dimension of a hard shoulder of the pathway, an arrangement pattern of a group of luminaires including the at least one luminaire along the pathway, a bracket length of the luminaire head of the at least one luminaire, an inclination of the luminaire head of the at least one luminaire, a presence of a base support for a luminaire, a location of the base support respective to the one or more circulation directions, a proximity with a neighboring building, characteristics of the neighboring building, a number of luminaire heads per base support, a presence of a conflict zone in the lighting site, a type of the pathway. 5
According to a preferred embodiment, receiving data related to a desired light distribution for the optical unit further comprises receiving at least one additional parameter from any of the following: a luminaire family, an installation budget, a power consumption per kilometer, a number of luminaires to be installed, a maximum wattage of the at least one luminaire to be installed, an aesthetical consideration, a type of light source, a glaring index, a luminaire managing option, a number of parts of a luminaire design, a lighting uniformity, a lighting intensity, an average illuminance, a total cost of ownership, a lifetime, a method of installation, an operating temperature, a recycling factor, a certificate, a commercial brand, an electrical connection type, a secondary functionality of the luminaire, a dimension of the optical unit. a type of accessory.
According to a preferred embodiment, for determining at least one set of one or more optical matrix models, sequentially the following steps are performed: - Selecting from the database one or more optical matrix models containing the received number of optical elements to be used, simulating the optical behavior of the selected one or more optical matrix models, - If the results of at least one simulation of the selected one or more optical matrix models meet the data related to the desired light distribution with optionally a predetermined tolerance, selecting the optical matrix model associated with that simulation for designing the optical unit, - Otherwise, selecting from the selected database one or more sets of identical optical matrix models, wherein the received number of optical elements is a multiple of the number of optical elements of the optical matrix model of each set, simulating the optical behavior of the selected one or more sets of identical matrix models, - If the results of at least one simulation of the selected one or more sets meet the data related to the desired light distribution with optionally a predetermined tolerance, selecting that set of identical optical matrix models for designing the optical unit.
In this way, an iterative process may be chosen for designing the luminaire, starting with the most standard option and progressively increasing the modularity of the design. A progressive design allows an easy interaction with a non-specialist user, increasing the user-friendliness. By starting with a standard optical matrix, costs may also be mitigated. It is noted that the orientations of identical optical matrix models of a set do not need necessarily to be the same.
According to a preferred embodiment. selecting one or more sets of identical optical matrix models comprises iterativelyy selecting sets of identical optical matrix models containing per optical matrix model a lower number of optical elements than during the previous iteration. In this way, the design may progressively become more complex, using progressively larger sets of smaller optical matrix models.
According to a preferred embodiment, the method further comprises the following steps: - Otherwise, optionally, selecting one or more accessories, simulating the optical behavior of a set of identical optical matrix models including the one or more accessories, - Optionally, if the results of the simulation meet the data related to the desired light distribution with optionally a predetermined tolerance, selecting that set of identical optical matrix models and accessories, - Otherwise, optionally proceeding according to the steps of any of the above embodiments, in particular according to the steps of the previous embodiments.
In this way, accessories may first be added to obtain the desired light distribution before considering mixing optical matrices in a more complex manner. Accessories may be regarded as mechanical part added to an optical element to modify the light distribution associated with that optical element. In an embodiment, one or more other accessories may be provided to the optical matrix, such as reflectors, backlights, prisms, collimators, diffusors, anti-reflection coatings and the like. For example, there may be associated a backlight element with some optical elements or with each optical element of the plurality of optical matrix. Those one or more accessories may be formed integrally with the optical matrix. In other embodiments, those one or more accessories may be mounted to/on/around the optical matrix via e.g. releasable fastening elements. It is noted that accessories may further be oriented/tilted as an additional step.
According to a preferred embodiment, the database further comprises associated with each matrix molding model a number of molding inserts available for producing by molding the optical matrix associated with that optical matrix model, and wherein determining at least one set of one or more optical matrix models amongst the plurality of optical matrix models for designing the optical unit further comprises excluding sets of one or more optical matrix models incompatible with the available molding inserts. By storing in the database the available molding inserts, the molding constraints may be taken into account during the design of the optical unit. In this way, cost constraints may be taken into account right at the beginning of the design of the optical unit.
Indeed creating (additional) molding inserts may be very costly. In this way, the design may take into account the available molding inserts for practically molding the optical unit, reducing costs associated with producing new molding inserts.

Figures 1A and 1B illustrate schematically a luminaire head with an optical unit which may be designed using the exemplary method according to an embodiment.
Figure 1A shows a luminaire 10 comprising a luminaire head 30 on a pole 20. Inside the luminaire head 30, there is provided an optical unit 40 positioned over light sources, preferably LED lights, to provide a predetermined light distribution. The optical characteristics of the optical unit influence the light distribution created by the light sources.
In Figure 1B, the optical unit 40 may be a lens plate comprising a plurality of optical elements 60, in particular optical lenses, arranged in a plurality of rows 51-54 of optical elements 60 and a frame
70 for holding the optical elements 60 and affixing the optical unit 40 to the rest of the luminaire head 30.
Figures 2A-2E illustrate examples of optical matrices for use in an exemplary method according to an embodiment.
For designing an optical unit, manufacturers may maintain a database comprising a plurality of optical matrix models M;, j being an integer higher than one, each optical matrix model M; being associated with an optical matrix 80;, and comprising at least one light distribution of that optical matrix 80; for at least one predetermined orientation, and an indication of further possible orientations. lt is noted that the indication may well contain the information that no other orientations are envisaged. For example, an optical matrix model M; associated with an optical matrix 80; as shown in Figure 2A may comprise a light distribution of that optical matrix 80 for an orientation of zero degrees, and an indication that the optical matrix 801 may also be used in a second orientation, in which for instance the optical matrix is turned by 180 degrees around an axis perpendicular to the plane of the optical matrix 80;. Alternatively a separate optical matrix model
Mj may be created for each orientation of each optical matrix 80.
The optical matrices 80; may be regarded as the building blocks available for building the optical properties of an optical unit 40. An optical matrix 80; may comprise one or more optical elements 60 and may be regarded as a physical sub-element of an optical unit 40. An optical matrix 80; may be any one or a combination of the following: an individual optical element 60 as illustrated in
Figure 2C, a row of identical optical elements 60 as illustrated in Figure 2B, a row of different optical elements 60, an array of identical optical elements 60 as illustrated in Figures 2D and 2E, an array of different optical elements 60 as illustrated in Figure 2A.
Figures 2D and 2E illustrate how an optical matrix 80,4 may have more than one orientation. The frame 70 may be used as a reference point on the optical matrix 80,4 to locate a privileged direction of lighting, illustrated by an arrow in the Figures 2D and 2E. The orientations of an optical matrix 80; may be related to a rotation around a first axis and/or a tilt around a second axis different form the first axis of each optical matrix. The optical matrix 804 of Figure 2E is rotated 180 degrees with respect to the optical unit 40b of Figure 2D around an axis A perpendicular to the plane of the optical matrix 804. In such cases, a model M4 may be stored in the database associated with the optical matrix 804, the model Ma comprising a light distribution of that optical matrix 804 in the orientation of zero degrees as shown in Figure 2D, and an indication that an orientation of 180 degrees is also possible for that optical matrix 804. Alternatively, multiples models for each orientation of each optical matrix may be stored in the database.
Figures 3A and 3B illustrate different installations configurations for a luminaire and their effect on the associated light distributions of the luminaire. As is well known in the art, when designing a luminaire, a desired light distribution may be derived from an installation configuration comprising luminaire installation characteristics related to the lighting site. A luminaire installation characteristic may correspond to an optical characteristic of the environment of the lighting site to be illuminated, and/or to dimensions relevant for the installation of a luminaire. The lighting site corresponds to the location for installing a luminaire 10, comprising at least one luminaire head 30, optionally combined with an associated luminaire head bracket, on a base support 10 of the lighting site, e.g. a luminaire pole.
Figure 3A illustrates how a first light distribution Da may be derived from a first installation configuration ConfigA, corresponding to lighting site with two pedestrian sidewalks and two vehicle lanes with given dimensions, while Figure 3B illustrates how a second light distribution Dg may be derived from a second installation configuration ConfigB, corresponding to lighting site with only two vehicles’ lanes with given dimensions.
The lighting site may correspond to any space to be illuminated with a location for installing at least one luminaire. The lighting site typically comprises a pathway that can be taken by vehicles and/or pedestrians. The pathway may be a pathway on a lighting site suitable for outdoor luminaires. By lighting site for outdoor luminaires, it is meant roads, tunnels, industrial plants, stadiums, airports, harbors, rail stations, campuses, parks, cycle paths, pedestrian paths, or pedestrian zones for example, and outdoor luminaires can be used notably for the lighting of an outdoor area, such as roads and residential areas in the public domain, private parking areas and access roads to private building infrastructures, etc. In other embodiments according to the invention, the pathway may be located indoors, such as in a warehouse or an industry hall.
In the context of a computer-implemented method for designing the optical unit of at least one luminaire, receiving data related to a desired light distribution may thus amount to receiving at least one luminaire installation characteristic and/or a lighting regulation. The at least one laminaire installation characteristic and/or a lighting regulation may be received from a user via input means, for instance via a keyboard, a touchscreen or a mouse, or extracted from other input data.
The installation characteristic may comprise any one or more of the following: a pathway width, an interval distance between two neighboring laminaire base supports, a pathway surface material,
pathway surface optical properties, a height of a luminaire head of the at least one luminaire, a number of lanes of the pathway, one or more circulation directions of the pathway, a lateral distance between the pathway and the at least one luminaire base support, a lateral dimension of a hard shoulder of the pathway, an arrangement pattern of a group of luminaires including the at least one luminaire along the pathway, a bracket length of the luminaire head of the at least one laminaire, an inclination of the laminaire head of the at least one luminaire, a presence of a base support for a luminaire, a location of the base support respective to the one or more circulation directions, a proximity with a neighboring building, characteristics of the neighboring building, a number of luminaire heads per base support, a presence of a conflict zone in the lighting site, a type of the pathway. The conflict zone may be defined as a zone where there is an increased potential for collision between road users, e.g., entry or exit lanes to the highway, crossroads, roundabouts, pedestrian crossings, etc.
A lighting regulation may be a public road lighting standard or recommendations such as EN 13201, EN 13032, IES RP-8, CIE 115, CIE 140 respective to the environment of the lighting site, thereby allowing for an illumination giving a visibility above a predetermined level for users of the lighting site, as well as giving a predetermined illumination safety, e.g., illumination intensity below a blinding intensity, light emitted within a certain arc to avoid glaring angles, illuminance and uniformity among others.
There further may be provided a regulation database which may be a nation-wide database, a region-wide database, a city-wide database, or a local-wide database. In an embodiment, the obtaining of the lighting regulation may be based on the geo-coordinates of the lighting site.
Additionally or alternatively, the obtaining of the lighting regulation may be at least partially based on the extracted installation characteristic, e.g., the number of lanes of the pathway. In an embodiment, the obtaining of the lighting regulation may be followed by a manual correction or confirmation of the lighting regulation associated to the lighting site.
Also, the obtaining of the lighting regulation may be achieved by a manual entry.
In addition, receiving data related to a desired light distribution for the optical unit may further comprise receiving at least one additional parameter from any of the following: a luminaire family, an installation budget, a power consumption per kilometer, a number of luminaires to be installed, a maximum wattage of the at least one luminaire to be installed, an aesthetical consideration, a type of light source, a glaring index, a luminaire managing option, a number of parts of a luminaire design, a lighting uniformity, a lighting intensity, an average illuminance, a total cost of ownership, a lifetime, a method of installation, an operating temperature, a recycling factor, a certificate, a commercial brand, an electrical connection type, a secondary functionality of the luminaire, a dimension of the optical unit, a type of accessory.
Figure 4 illustrates the steps of an exemplary method according to an embodiment.
A computer-implemented method for designing an optical unit for a luminaire of an embodiment may comprise: - step 401 for receiving data related to a desired light distribution for the optical unit, - step 402 providing a database comprising a plurality of optical matrix models, each optical matrix model being associated with an optical matrix and comprising at least one light distribution of that optical matrix for at least one predetermined orientation, and an indication of further possible orientations - and step 403 for using the database and the received data, determining at least one set of one or more optical matrix models amongst the plurality of optical matrix models for designing the optical unit.
According to an embodiment, determining at least one set of one or more optical matrix models, comprises selecting for each set one or more optical matrix models, and determining for each optical matrix model how many optical matrix models need to be included in said set.
The method may further comprise receiving a number of optical elements to be used in the optical unit. A user may input the number of light sources to be used in the luminaire 10 and thus the number of optical elements 60 to be used in the optical unit 40. This physical constraints may be related to an additional parameter from any of the following : a luminaire family, an installation budget, a power consumption per kilometer, a number of luminaires to be installed, a maximum wattage of the at least one luminaire to be installed, an aesthetical consideration, a type of light source, a glaring index, a luminaire managing option, a number of parts of a luminaire design, a lighting uniformity, a lighting intensity, an average illuminance, a total cost of ownership, a lifetime, a method of installation, an operating temperature, a recycling factor, a certificate, a commercial brand, an electrical connection type, a secondary functionality of the luminaire, a dimension of the optical unit, a type of accessory.
According to an embodiment, step 403 may comprise the following steps: - Selecting from the database one or more optical matrix models containing the received number of optical elements to be used, simulating the optical behavior of the selected one or more optical matrix models,
- If the results of at least one simulation of the selected one or more optical matrix models meet the data related to the desired light distribution with optionally a predetermined tolerance, selecting the optical matrix model associated with that simulation for designing the optical unit, - Otherwise, selecting from the selected database one or more sets of identical optical matrix models, wherein the received number of optical elements is a multiple of the number of optical elements of the optical matric model of each set, simulating the optical behavior of the selected one or more sets of identical matrix models, - Ifthe results of at least one simulation of the selected one or more sets meet the desired light distribution with optionally a predetermined tolerance, selecting that set of identical optical matrix models for designing the optical unit.
It is noted that the orientations of identical optical matrix models of a set do not need necessarily to be the same.
Incase the results of the above simulation still do not meet the data related to the desired light distribution, step 403 may then comprise: - optionally, selecting one or more accessories, simulating the optical behavior of a set of identical optical matrix models including the one or more accessories, - optionally, if the results of the simulation meet the data related to the desired light distribution with optionally a predetermined tolerance, selecting that set of identical optical matrix models and accessories,
In case the results of the above simulation still do not meet the data related to the desired light distribution, steps 403 may then further operate according to Figure 5 illustrating the steps of an exemplary method according to another embodiment.
The method of Figure 5 may comprise: - step 501: providing a database as in step 402 - step 502: receiving data related to a desired light distribution as in step 401. - step 503: determining a plurality of sets of one or more optical matrix models from the plurality of optical matrix models of the database, - step 504: simulating the optical behavior of said plurality of sets of one or more optical matrix models, - and step 505: selecting at least one set of one or more optical matrix models meeting the data related to the desired light distribution, optionally with a predetermined tolerance.
It is noted that steps 501 and 502, respectively 401, 402 may be performed in any order, depending on user preferences.
It is further noted that if none of the results of step 504 meet the data related to the desired light distribution with optionally a predetermined tolerance, the method may provide a request to update the database triggering the addition of at least one new optical matrix model, derived from the closest set.
Step 501 may comprise accessing a locally stored database or one or more databases available on servers of luminaire producers, to obtain optical matrix models of optical matrices from one or more producers. A model of an optical matrix may contain all optical characteristics of that optical matrix necessary for simulating the optical behavior of that optical matrix in terms of light distribution in any installation configuration.
Step 502 may further comprise receiving the number of optical elements to be used in the optical anit. The number of optical elements to be used in the optical unit may be a physical constraint and may be related among others to a type of luminaire, or a size of a luminaire housing. In this way, the user may limit the possible sets of one or more optical matrix models to meet other physical constraints of the optical unit design. Step 502 may then comprise determining all possible sets of one or more optical matrix models matching the received number of optical elements in the optical unit.
Step 504 may further comprise: - ranking the possible sets of one or more optical matrix models according to a flux associated with each set and derived from each simulation, - selecting among the ranked sets the set of one or more optical matrix models with the lowest flux.
By simulated flux of a set is meant the minimum light flux necessary to obtain the desired light distribution using that set of optical matrix models. In this way, the most efficient set of optical matrix models can be retrieved. In an embodiment, the flux may be used as criteria for optimization to help reduce the number of solutions presented to a user to improve his experience.
In an embodiment, the method may further comprise, using the database and the received data, determining orientations of the one or more optical matrix models of the at least one set of one or more optical matrix models. In particular determining orientations of the matrix models of the least one set may comprise determining a rotation around a first axis and/or a tilt around a second axis different form the first axis of each optical matrix model.
Figure 6 illustrates a computer-controlled system for implementing the computer-implemented methods of the embodiments of the present invention, in particular as illustrate din Figures 4 and 5.
The system 600 may comprise data input means 601 adapted to receive data related to a desired light distribution for the optical unit, a memory 602 configured to store a database comprising a plurality of optical matrix models, a display 604, and a processor 603 coupled the data input means 601, the memory 602 and the display 604. The processor 603 is contigured for performing the steps of the computer- implemented method of the previous embodiments and outputting the at least one set of one or more optical matrix models Mj amongst the plurality of optical matrix models Mj for designing the optical unit 40 to a user via the display 604.
Figure 7 shows possible results obtained with an exemplary method according to an embodiment, for a family of luminaires. Using the computer-implemented method of the previous embodiments it is for instance possible to design multiple optical units 40,-40p for a family of luminaires A-D to be installed for a large project covering a plurality of different lighting sites, like for instance a highway with tunnels, bridges, four lanes’ sections, tollgates etc. The optical units 404-40p are modular combinations of one or more optical matrices 80,-80F depending on the lighting site associated which each sort of luminaire. The computer-implemented method may enable to reuse existing optical matrices like optical matrix 80a of optical unit 40a in combination with other existing optical matrices 805-80, to build up a whole range of lighting solutions depending on the needs of the project.
According to another aspect, Figures 8A-8C deal with molding consideration which may be taken into account in the computer-implemented method according to another embodiment. According to an embodiment, the database of Figures 4-6 may further comprise, associated with each optical matrix model, a number of molding inserts available for producing by molding the optical matrix associated with a respective optical matrix model. Step 403 of the computer-implemented method for designing an optical unit of Figure 4 may then further comprise excluding sets of one or more optical matrix models incompatible with the available molding inserts. For example, should the computer-implemented method determine that a set of a given number, x, of identical optical matrix models would meet the data related to the desired light distribution, but the database contains the information that there not enough molding inserts available, i.e. less available molding inserts than the given number x, associated with that optical matrix model, then that set would be excluded from the final solution proposed by the computer-implemented method. In this way the investment in new molding inserts may be reduced to the strict minimum when for instance no solution could be retrieved using existing molding inserts.
According to an aspect of the invention, a first method for producing an optical unit may be provided comprising the method of any of the previous embodiments. After determining using the exemplary computer-controlled method a determined at least one set of optical matrix models, a production method may comprise generating/collecting at least one set of one or more optical matrices by molding the optical unit using molding inserts associated with the determined at least one set of one or more optical matrix models.
Figures 8A and 8B show exploded perspective views of a molding system for molding an optical unit with four rows of five optical elements (similar to the optical matrix disclosed in Figures 2D and 2E). Figure 8C shows a side view of the molding system of Figures 8A and 8B. The molding system may comprise a plurality of molding inserts 90 and 95 comprising a plurality of female molding inserts 90 (only one, element 90: associated with a theoretical optical matrix 80: is represented), a plurality of male molding inserts 95 (only one, element 95: associated with the theoretical optical matrix 802 is represented), a first frame 100 for receiving the plurality of female molding inserts 90 and a second frame 105 for receiving the plurality of female molding inserts 90.
In the example shown, the male and female molding inserts 90; and 95; would, if taken in isolation, form together a mold to produce by molding an optical matrix 80; using known molding techniques. In the example an optical matrix 80: comprising a row of five identical optical lenses/lenses has been represented. Yet a different number/arrangement of optical elements may be envisaged by a skilled person without departing from the concept behind the invention. By arranging a plurality of male and female molding inserts associated with a plurality of optical matrices inside the respective frames 100 and 105, an optical unit composed of a set of optical matrices may be produced by molding. The optical unit produced in this manner (not represented) may then be an integral element in which material is molded in between the male/female molding inserts 90 and 95 and the frames 1001 and 105 to form a single optical unit plate. The frame 100 and the molding inserts 90 may represent a female side of a mold, while the frame 105 and the molding inserts 95 may represent a male side of a mold. Between the female and male sides of such a mold, molding material may be injected to obtain by molding an optical unit.
Figure 8D shows an enlarged view of a frame 105 for receiving a plurality of male molding inserts 95, like for instance the molding insert 95.. The frames 100, respectively 105, may be specific to a set of molding inserts 90, respectively 95, and a stock of available frames may be at the disposition of a user. In an embodiment, a frame 105 may comprise guiding elements 110 and 120 meant to interact with the molding insert 952 when inserted in a given orientation. The guiding elements 110 and 120 may avoid that a user may insert the molding insert 95: in a orientation not intended with respect to the frame 105. The position and number of guiding elements 110, 120 may be specific to a set of molding inserts 95 associated with a set of optical matrices 80, associated in turn with a determined set of one or more optical matrix models M obtained according to the previous exemplary method. The frame 105 may further comprise a recess 130 for inserting a molding insert (not represented) for labelling the final optical unit. Similar considerations concerning guiding elements and labelling options, may apply to the other frame 100 for receiving the female molding inserts 90. The molding inserts 95, or 90, may optionally comprise a labelling area for labelling the associated optical matrix.
Figure 9 illustrates an embodiment where an optical unit is produced by molding using a set of molding inserts determined according to an exemplary method according to an embodiment. The optical unit 40A of Figure 9 may be produced by molding using the molding inserts 90, 95 and frame parts 100 and 105 as illustrated in Figures 8A-8D. In the example of Figure 9, the optical unit 40A may have been produced using a molding system comprising three types of male/female molding inserts 90, 95 (one type for the two male/female molding inserts in the center of the array, two different types of male/female molding inserts on the sides of the array). The frames 100 and 105 may then be configured to guide the molding inserts 90, 95 to insure the correct orientation of the optical elements. Optionally accessories may also be taken into account when molding the optical unit by inserting additional molding parts for molding said accessories.
According to another aspect of the invention, a second method for producing an optical unit may be provided comprising the method of any of the previous embodiments. After determining using a computer-controlled system a determined at least one set of optical matrix models, a production method may comprise collecting a plurality of optical matrices associated with the determined at least one set of optical matrix models from a stock of available optical matrices and forming the optical unit with the collected optical matrices.
Figure 10 illustrates an embodiment where an optical unit 40g is produced by assembling a set of one or more optical matrices 80 mold separately, the set being determined according to an exemplary method according to any of the previous embodiments. In an example, after determining using a computer-controlled system a determined at least one set of optical matrix models M, a production method may comprise collecting at least one set of optical matrices 80» corresponding with the determined at least one set of optical matrix models M: from a stock of available optical matrices 80 and forming the optical unit 40g with the collected optical matrices 80.
In an example, the production method may further comprise collecting a frame 70; for holding the collected optical matrices 80: from a stock of available frames 70. Forming the optical unit 40g with the collected optical matrices 80 may comprise connecting together the collected optical matrices 802 and the collected frame 70s. Connecting together the collected optical matrices 802 and the collected frame 70s may comprise placing the collected optical matrices 802 on the collected frame 70g according to determined orientations of the one or more optical matrix models
Mb. Connecting the collected optical matrices 80; on the collected frame 708 may further comprise attaching the collected optical matrices 802 on said frame 70g by any one of the following methods: welding, gluing, snap-fitting or any other known suitable technique. Alternatively, collected optical matrices 80 may be attached directly a printed circuit board holding the light sources. In another alternative, the collected optical matrices 80 may be attached together by known techniques.
During the production, additional steps may include attaching accessories to the collected optical matrices 80 to the optical matrices and/or the frame.
Whilst the principles of the invention have been set out above in connection with specific embodiments, it is understood that this description is merely made by way of example and not as a limitation of the scope of protection which is determined by the appended claims.
