Technical Field

[0001] The present invention relates to the technical field of light source simulation, and particularly to a light efficiency simulation method for a lamp. Background Art

[0002] In the current market, the requirements for lamps are no longer limited to lighting. Lamps that can simulate outdoor natural ambient light are gradually favored by the market and are widely used in indoor lighting such as homes, office buildings, shopping malls, stadiums, stations, airports, etc. These lamps can simulate various scenarios, such as light in multiple scenarios like simulated morning light and sunset.

[0003] Currently, during the design stage, when debugging such lamps, it is usually necessary to first write a program and then burn it. During this process, various operations such as unified marking of color positions and brightness are required, and problems can only be discovered during the lighting test, which takes a relatively long time overall.

[0004] In view of this, it is indeed necessary to provide a light efficiency simulation method for lamps to make the efficiency higher during the design and debugging stage. Summary of the Invention

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Here, it should be noted that in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution of the present invention are shown in the drawings, and other details less related to the present invention are omitted.

[0030] In addition, it should also be noted that the term "comprises", "comprising" or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0031] The present invention provides a simulation method for lighting, and the method will be described below in conjunction with the specific embodiments.

[0032] The simulation method for lighting specifically includes the following steps:

[0033] In the simulation software, an initial light source model 100 is established according to the positions of the light-emitting units in the lamp. The light source model 100 is as Figure 2 shown. The light source model 100 includes a plurality of simulation modules 110 corresponding to the positions of the light-emitting units;

[0034] Import the preset spectra into each simulation module 110 of the initial light source model 100 to establish a light source model, including: importing each preset spectrum corresponding to two or more colors into the same simulation module;

[0035] Input the scene to be simulated; and obtain the light effect simulation result according to the scene to be simulated and the light source model 100, including: adjusting the brightness value of the simulation module 110 at the corresponding position in the light source model 100 according to the scene to be simulated to obtain the light effect simulation effect;

[0036] Judge whether the light effect simulation result meets the standard according to the scene to be simulated; when the light effect simulation result does not meet the standard, adjust the brightness value of the simulation module 110 at the corresponding position in the light source model 100 again;

[0037] When the light effect simulation result meets the standard, end the simulation.

[0038] In the simulation method of the lighting of the present invention, the preset spectra corresponding to different colors are directly imported onto the simulation module 110 in the light source model 100, as Figure 4 shown. Then, directly adjust the brightness values of the preset spectra of different colors to be displayed in each simulation module 110, and compare the display effect of the adjusted light source model 100 with the scene to be simulated, and the similarity between the scene display effect of the light source model 100 and the scene to be simulated can be determined. Compared with the traditional simulation method, the simulation method of the lighting of the present invention is more efficient and convenient. By using the spectra corresponding to various colors measured in the lamp to be simulated as the preset spectra and substituting them onto the light source model 100 in the simulation software, the final presented display effect is closer to the display effect of the lamp to be simulated, with a higher reduction degree, and steps such as program burning can be omitted, greatly improving the efficiency of the simulation test of the lamp.

[0039] In this embodiment, importing the preset spectra into each simulation module 110 of the initial light source model to establish the light source model 100 further includes: importing different preset spectra between at least two of the simulation modules 110 in each simulation module 110. For example, the simulation module A imports spectrum 1 and spectrum 2, and the simulation module B imports a spectrum different from spectrum 1 and / or spectrum 2, which can achieve a richer and more flexible scene effect.

[0040] In this embodiment, there are four preset spectra corresponding to four different colors imported into the simulation module 110. Specifically, the preset spectra corresponding to at least two colors among white, green, blue, and red are imported into the same simulation module. The combination of the above four colors can make the color of the displayed light more abundant and the light mixing effect better. In some other embodiments, according to the actual situation of the spectra measured in the lamp to be simulated, preset spectra of other quantities or colors can also be imported, and the present invention places no limitation thereon.

[0041] As Figure 3 shown, in this embodiment, the simulation module 110 includes a first simulation module 111 and a second simulation module 112. The preset spectra corresponding to the two colors of red and green are respectively imported into two sub-modules in the first simulation module 111, and the preset spectra corresponding to the two colors of white and blue are imported into two sub-modules in the second simulation module 112. The first simulation module 111 and the second simulation module 112 are arranged alternately in sequence, and the preset spectra of two different colors in two adjacent first simulation modules 111 are distributed in reverse. Similarly, the preset spectra of two different colors in two adjacent second simulation modules 112 are also distributed in reverse. By alternately distributing different types of simulation modules 110 and reversing the distribution of the same type of simulation modules 110, the light color displayed on the light source model 100 can be made more uniform, and at the same time, the effects of multiple different scenarios can be simulated.

[0042] To facilitate the rapid adjustment of the brightness values of each simulation module containing preset spectra of different colors, in this embodiment, the simulation modules 110 on the light source model 100 are divided into multiple modules. Specifically, the complete permutation and combination between the first simulation module 111 and the second simulation module 112 is divided into one module, and according to the selected scenario to be simulated, the brightness values of each simulation module or each sub-module in the module at the corresponding position are adjusted. Each module includes spectra of all colors, that is, each module includes sub-modules of the four colors of white, green, blue, and red, which can effectively improve the efficiency of simulation testing. The positions of the simulation modules 110 in each module are distributed in at least one of the forms of horizontal, vertical, array, and ring.

[0043] The simulation modules 110 in the established light source model 100 are arranged regularly. Specifically, the simulation modules 110 can be distributed in any one of the forms of multiple concentric circles, multiple loop-shaped distributions, and array distributions. The arrangement mode of the simulation modules 110 is consistent with the arrangement mode on the lamp to be simulated to improve the reduction degree of the simulation. In some other embodiments, according to the actual situation of the lamp to be simulated as needed, the above-mentioned simulation modules 110 can also be distributed in other shapes, and the present invention places no limitation thereon.

[0044] As Figure 2As shown, in this embodiment, the simulation modules 110 are arranged in the form of multiple concentric circles, and the number of simulation modules 110 in each circle is a multiple of 6 or 7 or 8. Specifically, the number of simulation modules 110 in each concentric circle needs to be determined according to the voltage of the light-emitting units on the lamp to be simulated and the driving voltage of the lamp.

[0045] Specifically, there are Ri circles of simulation modules 110 arranged in the light source model 100, where Ri≥2. It is preset that the number of simulation modules 110 in the first R1 circle is N, then the number of simulation modules 110 in the second R2 circle is 2N, and so on until the number of simulation modules 110 in the Ri circle is i*N. The total number of simulation modules 110 in the light source model 100 is (1 + i)*i*N.

[0046] In this embodiment, when grouping the simulation modules 110 in the light source model 100, N simulation modules 110 in each circle are set as a module, that is, the first circle is 1 module, the second circle is 2 modules, and so on until the i-th circle is i modules. Then all the simulation modules 110 on the light source model 100 are divided into (1 + i)*i / 2 modules in total, which is equivalent to being able to adjust (1 + i)*i / 2 groups of light beams. At the same time, since the preset spectral data corresponding to four different colors are imported into the simulation modules 110, the sub-modules with the same preset spectral data in each module are adjusted in brightness simultaneously, that is, a total of 4*(1 + i)*i / 2 areas can be adjusted in terms of various colors and brightness. By adjusting the brightness values of each sub-module in each module, various changes in light can be achieved. According to the actually selected scene, the proportion of the spectra of the four colors in each module is adjusted, and the adjusted display effect is compared with the scene to be simulated.

[0047] The simulation modules 110 in each module are distributed horizontally or vertically or in an array or in a ring. In some other embodiments, they can also be distributed in other custom shapes.

[0048] The scenes to be simulated at least include sunset, sunrise, dusk, and the scenes of spring, summer, autumn, and winter. However, the selection of scenes in the lighting simulation method of the present invention is not limited to the above-listed several scenes. Using the four spectra of white, green, blue, and red, the effects of various more different scenes can be simulated more realistically, such as complex scenes like the bright moon rising over the sea, etc., which are not enumerated one by one in the specification.

[0049] In this embodiment, the lighting simulation method is mainly operated through SolidWorks software. In other embodiments, other simulation software can also be selected, and the present invention does not limit this.

[0050] In some embodiments, considering the uniformity of the overall display effect of the light source model 100 and the grouping of colors, the complete permutations and combinations between the first simulation module 111 and the second simulation module 112 are divided into a module, and each module can have an overall brightness value. As Figure 3 shown, in this embodiment, each module includes two first simulation modules 111 and two second simulation modules 112. Two spectra, red and green, are imported onto the first simulation module 111, and two spectra, blue and white, are imported onto the second simulation module 112. The first simulation module 111 and the second simulation module 112 are horizontally distributed, and the first simulation module 111 and the second simulation module 112 are staggered, and the spectra on two spaced-apart first simulation modules 111 or second simulation modules 112 are distributed in reverse.

[0051] As Figure 2 shown, in this embodiment, a total of 448 simulation modules 110 are arranged on the established light source model 100. The numbers of simulation modules 110 from the inner circle to the outer circle are 16, 32, 48, 64, 80, 96, and 112 in sequence. That is, in this embodiment, the 448 simulation modules 110 on the light source substrate 120 are divided into 28 modules. By adjusting the brightness values of the simulation modules 110 in each module, the simulation results can be obtained quickly.

[0052] In some embodiments, after establishing the initial light source model, a brightness uniformity test is performed on the initial light source model. According to the brightness uniformity test value, the positions of the simulation modules are adjusted. For example, when the simulation modules are arranged in multiple concentric circles, the spacing between the simulation modules in each circle is adjusted until the brightness uniformity test value of the initial light source model is not lower than 85%. The brightness uniformity test value is the ratio of the lowest brightness value measured on the light source model to the highest brightness value.

[0053] To further improve the accuracy of the simulation results, after determining that the simulation results meet the standards, on the lamp that actually needs to be simulated, a lighting operation is performed according to the brightness values of the respective simulation modules 110 on the light source model 100 in the simulation software, and the actual effect of the lamp after lighting is compared with the scene effect in the simulation software to compare the differences between the two, and whether to adjust the brightness values of each group of simulation modules 110 is determined according to the comparison results.

[0054] In summary, for the lighting simulation method of the present invention, according to the actual situation of the lamp to be simulated, a light source model 100 is established in the simulation software. Each simulation module 110 on the light source model 100 is arranged according to a preset rule. The preset spectral data corresponding to the four colors of white, green, blue, and red measured in the lamp are directly imported into the simulation module 110. By directly adjusting the brightness values of the preset spectral data in each simulation module 110 in the simulation software, the simulation effect of the light source model 100 can be visually observed. At the same time, because all the actual spectra of the lamp are substituted into the light source model 100 in the simulation software, the similarity between the simulation result and the display effect of the real lamp is better, improving the accuracy of the simulation result and greatly improving the efficiency of the simulation test of the lamp.

[0055] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
