Description

The present invention relates to a method for automatically arranging interior lamps, and more particularly to a method for appropriately designing lighting and providing recommended arrangement lamps by analyzing parameters related to various interior spaces and furniture.

Lighting is indispensable to the lives of modern people. A lighting design with just the right brightness and an appropriate light source position arrangement can optimize the usage efficiency of each space, leading to an improvement in the texture of the interior design. Therefore, lighting design is indispensable for indoor space planning. For now, many large commercial facilities, exhibition spaces, public spaces and other buildings are assigned a professional lighting designer, who participates in the design of the entire interior space and provides suitable lighting design for the entire space. The expression can have a better effect.

Generally speaking, there are many space setting parameters that lighting designers should consider when designing lighting, such as the size of the space, the layout of the room, the setting of the function of using the space, the installation position of furniture, and the main. It includes parameters related to the user's age, solar intensity, etc., and these parameters also include a plurality of sub-parameters.

After the evaluation of the space setting parameters is completed, the appropriate item and number of lamps can be determined by comparing with the parameters of various commercially available lamps. The parameters of these lamps are the manufacturer name of the lamp, the fixture type, the illuminance at 1 meter (lux at 1 meter), the illuminance (lux), the lumen, the beam angle, and the color temperature. (Color temperature), color description of sunshine, color rendering index, tilt feature of lamp holder or adjustment of projection angle (tilt feature), dimming and expression (dimming), lighting equipment Includes fixture color, installation height of the lamp, installation diameter of the lamp, and so on.

Lighting designers usually select the appropriate lamp item and number based on the evaluation results of the spatial setting parameters, but may need to adjust the lamp position and brightness settings according to the needs of a special lighting plan. .. For example, in the case of a gallery, it is necessary to concentrate the light on the picture and darken other parts of this space, and in the case of a baby room, relatively dark and soft lighting is required. Even if more or brighter luminaires can be provided in the luminaire, the lighting designer still has to arrange the appropriate luminaires according to the needs of the special project.

After the lamp placement plan is completed, the lighting designer will perform a 2D and 3D rendering simulation with a computer program on the result of the plan to verify whether the lamp placement plan meets the set usage needs of this space. It can also be made to meet the set usage needs by readjusting the item, position or number of luminaires if there are unresponsive parts. However, such programs for 2D and 3D rendering simulations can reach 95% or more fidelity and have high resolution, but the technical hurdles are quite high, so they are specialized. The house has to do the work, and it takes more than a few hours to complete the 3D rendering simulation. For example, when it comes to programs such as 3D Max and Rhino that are often used in recent years, the essential operating conditions are as follows: (1) Since the fidelity of such programs is quite close to the actual situation, The demand for hardware standards is very high
(2) It takes time for the operator to set various parameters, and the parameter setting process is complicated. If one parameter is set incorrectly, an incorrect simulation result may be obtained.
(3) The operator is required to have specialized knowledge in related fields such as lighting design and IES.

Such a technique cannot be simulated for the general small and medium-sized interior design company or the general public about the effect of actually arranging the lamp before installing the lamp, and is evaluated based on the experience of the designer or the general public. And I have no choice but to imagine. Therefore, it is easy to bring about the result that the usability of the entire space is affected due to the improper arrangement of the lamps, or that some or all of the lamps must be replaced due to the wrong lamp selection.

An object of the present invention is to provide a method for automatically arranging lamps in a room.

According to one embodiment of the present invention, a method of arranging a lamp in an indoor space is provided, and the steps of the lamp arranging method of the present invention are as follows: (a) setting a first parameter set. The first parameter set relates to the space setting and function of the indoor space; (b) the second parameter set is set, and the second parameter set generation is the home appliances to be installed in the indoor space and / Or it is based on the characteristics and standards of the furniture; (c) the first parameter set and the second parameter set are analyzed, and the relative position in the indoor space where the home appliances and / or furniture are not installed and The area is calculated and a third parameter set is generated; and (d) the lighting parameter is generated by analyzing the relative relationship between the first parameter set, the second parameter set, and the third parameter set. .. Lighting parameters include lamp placement position, quantity, and recommended placement lamp illuminance, solar angle, and solar characteristics. Based on the generated lighting parameters, the method compares the values of the various lamps online or in the system database, i.e. the fourth parameter set, to the types of lamps in the recommended arrangement in the room space. A list of numbers or positions can be generated, as well as a 2D lighting layout map or a 3D lighting simulation diagram.

It is a flowchart of a preferable embodiment of this invention. FIG. 5 is a plan view of an unfurnished bedroom in a preferred embodiment of the present invention. FIG. 5 is a plan view of a furnished bedroom in a preferred embodiment of the present invention. It is a figure which shows the lamp arrangement in a preferable example of this invention.

It is a standard lighting arrangement database in a preferred embodiment of the present invention. It is a system lamp database in a preferred embodiment of the present invention.

The contents, features, functions and effects of the above and other techniques of the present invention will be clarified by the detailed description in the following preferred embodiments based on the accompanying drawings. It should be noted that the terms for the directions referred to in the following examples, such as up, down, left, right, front, back, etc., are merely the directions of the attached drawings. Therefore, the terminology used is only for explaining the present invention and not for limiting the present invention.

The present invention relates to a method in which a lamp can be automatically arranged in a room, obtains a lighting parameter range of a recommended arrangement by calculating and analyzing a plurality of types of parameters related to the arrangement of the lamp, and obtains the lighting parameter range and the present invention. By comparing with the lighting parameters of the standard arrangement data built into the method, the initial recommended arrangement method, that is, "where and how bright the lighting should be arranged in the indoor space", recommended arrangement Obtain the number of lamps and then compare them with the parameters of each manufacturer's lamps online or in a separate database to generate recommended placement lamp items, individual unit prices, and total prices.

The basic steps of the method according to the invention are as follows.

(A) First, the first parameter set is set, and the first parameter set relates to the space setting and function of the indoor space where the lamp arrangement is to be performed;
(B) Subsequently, a second parameter set is set for the features and standards of home appliances and / or furniture to be installed in the interior space;
(C) The first and second parameter sets are analyzed, the relative positions and areas in the room space where home appliances and / or furniture are not installed are calculated, and the third parameter set is generated. At this time, in this method, the relative relationship between the first parameter set, the second parameter set, and the third parameter set can be automatically analyzed, and the illumination parameters of the recommended arrangement can be generated. The contents of the lighting parameters include items such as the recommended placement position, number, and recommended usage brightness, solar radiation angle, and solar radiation characteristics.

Based on the generated lighting parameters, the method compares the values of the various lamps online or in the system database, i.e. the fourth parameter set, to the types of lamps in the recommended arrangement in the room space. A list of numbers or positions can be generated, as well as a 2D lighting layout map or a 3D lighting simulation diagram.

The first parameter set includes other parameters relating to the size, shape, height, function of use, position of columns or beams or doors / windows, and the characteristics of the interior space in which the lighting fixtures are arranged. Input of parameters such as size, shape, height, pillar and beam and door / window position of the indoor space is for calculating the required light intensity and average lighting arrangement position, and the setting of the function to be used is for the entire lighting. It is a way of expressing brightness and lighting. For example, a living room and a bedroom may have the same size of space and different functions, so that the method and number of lamp arrangements should be different.

In addition to the above parameters, the first parameter set may further include items such as user condition settings, sunshine, brightness, and contrast. The setting of user conditions refers to items such as the age, gender, occupation, and usage habits of the user, the sunshine represents the original distribution of natural light in the space, and the brightness and contrast are the space of the user. It expresses the expected feeling for the whole.

The second parameter set relates to furniture and home appliances installed indoors and includes the size, height, color of the home appliances and / or furniture, orientation or installation position with respect to the indoor space. For example, if you have a wall-mounted wooden wardrobe in your bedroom and the bed is located on the other side of the wooden wardrobe, increase the brightness near the wardrobe and decrease the brightness of the bed position when arranging the lights. You may. Alternatively, if a three-seat sofa is attached to the wall in the living room, a picture is installed above the wall surface, and the TV is installed on the other side facing the sofa, the brightness of the TV and the sofa should be used in the lighting design. You can increase the contrast of the light by increasing the brightness and decreasing the brightness between the TV and the sofa, and by creating the contrast in this way, you can add more visual layering to the entire space. You can also have it.

After the first parameter set and the second parameter set are set, the complete spatial arrangement is almost fixed, and the area in this space where furniture / home appliances (hereinafter referred to as "free space") are not installed and The position, that is, the third parameter described above, is also determined at the same time. In this method, the reason why the free area is also an option for analysis and reference is based on the ratio of the area between the free area and the entire space and the comparison between the free area and the relative position and area where the furniture / home appliances are installed. This is because it is necessary to finely adjust the contents such as the illumination arrangement position, the light intensity, the illumination light angle, and the light contrast. If the user adjusts the value of any one parameter in the first parameter set or the second parameter set at this stage, the third parameter is modified accordingly.

The method also includes a built-in database to provide corresponding standard lighting arrangement data for spatial settings of different functions used. This method sets data for allocating lighting (light) on average for a space where furniture and home appliances are not installed, based on the different functions used individually. Therefore, when furniture is not installed in a certain space, this method is used. Now, select the standard lighting arrangement data to be used based on the function of the space, and adjust the data proportionally based on the size of the actual space with the reference reference value dedicated to the space. can do. In other words, after the user inputs the function and magnitude of the space, the method automatically generates an exclusive reference reference value, and the lighting arrangement of this reference reference value is assigned to the space on average. ..

The built-in database in this method provides the corresponding lighting arrangement data as reference values for different furniture / home appliances. After the user inputs parameters such as furniture and home appliance layout, this method automatically analyzes the first parameter set, second parameter set, and third parameter set and compares them with the standard layout data to identify them. The lighting parameters can be obtained, and the information contained in them is "what specific position and how much brightness, solar radiation angle, solar radiation characteristics, light irradiation angle, light irradiation characteristics should be placed", and , The number of individual recommended placements. At the same time, in this method, a 2D plan view of furniture and lighting arrangement is generated based on the parameters of the first parameter set and the second parameter set set by the user, and a 3D simulation lighting effect diagram is generated based on this. It can also be generated for user reference.

In addition, in order to improve the efficiency of the simulation and to improve the problem that it takes a long time to complete the simulation like the conventional online 3D simulation program, in this method, the resolution in the simulation effect diagram is lowered. In particular, it reduces the resolution of elements that are not directly related to the lighting arrangement, such as furniture, home appliances, wall / ground shaping or color, but the size ratio of space and each furniture / home appliance, the effect that the lighting expresses, and the lighting arrangement. Leave the resolution etc. of other elements directly related to. For example, when simulating the arrangement of lighting fixtures in the living room, the 3D simulation diagram shows the installation position of the lighting fixtures, the area directly irradiated with light, the area not directly irradiated with light, indirect lighting, the shaded area, the color temperature, and the like. By doing so, it is possible to show information on the effect of arranging the lighting equipment; it is possible to express the size, orientation and effect of light irradiation of the entire arrangement with respect to the installation part in the room. The color of the wall / floor and the size and position of the hanging decoration are shown, but the pattern of the wall / floor and the color of the hanging decoration are not shown accurately; or by showing the position and size (large and small) of the sofa, the sofa The relative position and ratio between the light and the space appears, but it does not indicate that the material of the sofa is cloth or leather. With such a setting, the time required for the 3D rendering simulation can be shortened from several hours to several seconds, and the accuracy of placement and effect can be maintained, which is convenient and effective for the user.

In this method, after the extension function is further included and the lighting parameter is generated, the lighting parameter is compared with the information in the product information (brand, etc.) or the lighting related database published online. A fourth parameter set can be generated. The range of the fourth parameter set is lamp type, installation position, number, standard, manufacturer name, unit price range, total price, lighting type (fixture type), illuminance (lux calculation), beam angle (beam angle), beam angle. Bean angle range, color temperature, color description of sunshine, color rendering index, tilt feature of lamp holder or tilt feature, Includes parameters related to the standard or nature of the lamp, such as dimming, fixture color, installation height of the lamp, and installation diameter of the lamp. Not limited to. The user can freely select or rearrange the accepted lamp standard, manufacturer name, lamp, unit price range, or total price range of the information in the fourth parameter set, but of the lamp. When trying to modify items such as position and effect, the related settings can be changed by changing the first parameter set and the second parameter set.

In this method, input of a plurality of types of parameters is provided, and the user can freely select what kind of information is to be input. The more detailed the parameters entered, the closer the simulation effect is to the actual situation. This method may be used as an online system (platform) or may be used by individual computers as an offline system. Further, in order to achieve the above-mentioned object, a preferred embodiment according to the present invention will be described later.

Hereinafter, the structure and effect of preferred embodiments of the present invention will be described in detail with reference to the drawings.
