Festival of the Lights in OSAKA Executive Committee OfficeTel:06-4391-0120(9:00-18:00 / weekdays only)Until January 31, 2025*On the following dates, our hours will be extended and applications will be accepted on Saturdays, Sundays, and national holidays. 10/27 (Sun.) - 11/7 (Thu.), 12/8 (Sun.) - 12/26 (Thur.) 9:00 - 21:00 (also available on weekends and holidays)

This is a large-scale illumination that wraps Midosuji, the symbolic street of Osaka, in a gentle light. The path of light, which fascinates on a global scale, was certified as a world record in January 2015. Please enjoy the landmark lasers, projection mapping, and beautiful illumination that represents the history of Midosuji, the emblem of Osaka.

Rule of thumb: The closer the better, if you want to use the somewhat diffuse nature of the lighting in order to achieve soft illumination!

"Supporters' Trees" are ginkgo trees along Midosuji displayed with the LED message boards of companies and organizations supporting Midosuji Illumination. Come and see many encouraging messages.

"Box of Light," created by public participants at a pre-event workshop will be exhibited as a unique art piece in the ground of Kitamido. Approximately 400 boxes of lights will welcome visitors! Accompanied by music, the shimmering lights at your feet will ripple out like waves, creating a luxurious space that intertwines with the projection mapping and light performances held every 15 minutes. Please come to enjoy this splendid atmosphere. The content of the performance may change if there is another event in the precinct. To participate in the workshop,click here.

Not every "diffuse" light source is truly diffuse. Here a direct comparison of the above-mentioned lighting types. An almost perfect reflection-free illumination is only achieved using dome illumination.

Diffuse light is necessary for many applications, as soon as reflective, polished, glossy or metallic objects must be tested. It is particularly difficult if these surfaces are no longer perfectly flat, but individually shaped, wrinkled, curved or cylindrical.

Midosuji Ave., with its long history dating back to its opening in 1937, has witnessed the growth of Osaka. Midosuji Illumination 2024 unfolds the history that formed the base and the growth of each area of the city to what it is today, and expresses it through lightings.

A portion of your accommodation fee will be donated to the Midosuji Illumination Fund when you purchase “Festival of the lights in OSAKA Hotel Package” or “Midosuji Illumination Hotel Package.” The packages are available during the illumination period at hotels tied up with Osaka Prefecture.Check details here

Diffuse lightingOpenGL

Only a dome light is able to produce truly diffuse light, avoiding reflections on the component to the greatest extent. Due to the homogeneous incidence of light from all spatial directions, irregularities and scratches are also illuminated very softly, uniform material appears homogeneous.

The advantage of this lighting design is the "view" through the light source (in this case the mirror). The image as a whole looks very homogeneous and has only a general linear loss of light, the further the mirror moves away from the lamp. Tip: In order to avoid inhomogeneities, the illumination must be clearly larger than the area to be inspected.

The lights, continuously changing with a gradient of colors, express Osaka's dignified growth toward the Expo and beyond, illuminating the night cityscape.

Coaxial lighting, just like dome lights, must be very close to the object in order that the diffuse stray light can illuminate the surface very homogeneously. The longer the working distance, the more directed is the light; notches, scratches, etc. in the surface become more and more clearly visible again.

The further the light is away, the more the soft illumination by means of the little stray light gets lost and the light becomes more and more directed. Bevels, engravings and errors, etc. which represent a no longer perfectly planar surface are still more emphasised.

Variations of this illumination are only slightly arched lights that can illuminate a much smaller solid angle. Tunnel-like dome illuminations have an elongated dome shape and are ideal for illuminating cylindrical objects.

These images typically appear rather "featureless". Reflections, shadows, surface irregularities, scratches, etc. are suppressed. Up to a surface angle of almost + / - 45 degrees, structures are illuminated uniformly. Other materials and components with different colours are clearly visible only now.

Diffuselight vs direct light

The light performance adds colorful hues to the shadows of people moving through the space. Just by being there, you become a part of the art. Additionally, by scanning a 2D code for AR, you can take special photos with a limited- time photo frame.

This type of lighting couples light into the optical path from the side (coaxially). This is done with the help of a semi-transparent mirror which is illuminated sidewards and casts light downwards on the test object. The object reflects the light which reaches the camera through the semi-transparent mirror.

Coaxial illuminations are perfect for highly reflective materials which have a relatively flat surface. They are very homogeneous, but rather directed and produce contrast at edges and greater curvatures.

If you want to illuminate a test object as diffusely as possible, it is usually necessary to choose a small working distance. With increasing distance, the light source appears more direct. The consequence is a smaller illuminated solid angle. Stronger object curvatures are no longer illuminated.

In the easiest case, a simple incident light illumination can be equipped with a diffuser, e.g. an LED ring light with diffusing panel. In this way, the directed light can be homogenised slightly better. Individual LEDs, for example, are no longer discernible on a reflecting material. The light, however, is still quite strongly directed and mainly comes from the direction of the illumination.
