Applications/Examples of results

By using lighting devices that utilize LEDs, such as those represented by machine vision, and by confirming the design performance of lighting equipment like streetlights and indoor lights, it is possible to shorten the prototyping process. With user-friendly operability, it can also be used by non-optical engineers who do not utilize specialized design software.

Detailed information

• 

  General lighting and simulation of indoor downlights. Nine white LEDs are used as the light source, efficiently focusing light with reflectors and Fresnel lenses, and the illuminance distribution is analyzed over a range of 3 meters at a distance of about 2 meters. By changing the performance of the reflectors and lenses, we can verify and examine the content through simulation. The left side shows the illuminance distribution designed with a beam angle of 45 degrees, while the right side shows the illuminance distribution designed with a beam angle expanded to 55 degrees. In addition to quantitative analysis, we can also visually indicate the spread and brightness of the spots by aligning the peak illuminance in this manner.

• 

  Simulation of ring lighting in the inspection/measurement equipment field. The outer 24 LEDs and the inner 16 LEDs are arranged in a ring shape. Using the API module of the software option, a 10mm square illuminated surface is placed at a distance of 70mm, and a Gaussian distribution with more than 50% illuminance value in a 5mm area is confirmed. Furthermore, a 3D CAD model to be used as a workpiece can be placed to examine in advance where the areas of low illumination are.

• 

  This is a simulation to confirm the state of imaging with a camera using lenses in the field of machine vision. First, as STEP:1, we will create and examine a model of a flat light source with no unevenness in the lighting section. We will arrange 25 LEDs in an array, and the light rays, including reflections inside the box, will ultimately be emitted through a diffusion plate. The diffusion plate will be analyzed using a goniophotometer to graph the scattered data, and the parameters calculated from the fitted graph will be used as the simulation model. We will conduct a luminance simulation to check whether the diffused surface lighting examined here is uniformly illuminated over the area of the work being inspected, and we will verify this with the luminance distribution.

• 

  This is a simulation using the diffuse surface lighting modeled in STEP1, consisting of four models: diffuse surface lighting, the workpiece, the lens, and the receiving surface. The workpiece and the receiving surface have a relationship between the subject and the image plane. By using a lens, it becomes possible to simulate and check the appearance as if it were captured by a camera.

• 

  This is a simulation model that uses the infrared light emitted by a halogen lamp as a heat source to heat the workpiece. The model created in 3D CAD is evaluated, and by changing the contents of the reflector and halogen light source, the uniformity of the radiation intensity distribution is checked. The spectral characteristics of the light source can be specified from 100 nm to 10,000 nm, allowing for the observation of light behavior even in wavelength ranges outside the visible spectrum, which are difficult to confirm visually.

• 

  This is an example of examining a UV curing irradiation device. It involves arranging multiple UV LEDs in combination with mirrors to enhance uniformity on the irradiation surface. In the initial examination, considering versatility, a completely diffused light source is used first, comparing illuminance distribution while varying the pitch of the LEDs to determine the optimal spacing. Then, simulations are conducted using the Ray files of the actual LEDs to inform adjustments in subsequent prototypes. Additionally, a workpiece created with 3D CAD is arranged, and irradiation uniformity is checked in advance through simulations.
