Leucht-Bäume

After first tests 3 days ago I optimized the LED modules a bit and built a few more. I currently have 14 of them. That seems to me to be a little bit less, for what I intend to do. All of them were in use that night and I could have used a few more ... Photos of the current light modules can be found at the bottom of this page.

Today I am in the same place as three days ago.

A row of trees along the way

There I placed a module with four LEDs on each of the small trees. Alternating one tree red, the next tree green.

I lit the trunk of the big tree with a module in yellow, and the branches with four modules, each with four blue LEDs. That could have been a few more, but here I ran out of material.

Illuminated Tree

The high brightness of the sky and foreground comes from the moonlight. Here is two nights before the full moon. That's why you can't see many stars.

Panoramas

Okay, so much for the preparation. So now we come to the panoramas.

Here is the first panorama of the night. The battery in the front red tree is already weakening a little ... (it is somewhat defective, the other batteries last considerably longer. Will be replaced soon.)

Panorama 1

Shot on April 5th, 2020 at about 11:30 pm.

Camera data:
Canon EOS 6D (Mark I)
Focal length: 16 mm
Aperture: f / 2.8
ISO: 1250
Exposure time: 20 s
17 Pictures

Panorama resolution: 16000 x 8000

Bightness Moon: ca. 93%

This was the second test of my LED lamps. But there is still a lot to optimize.

Here is the second panorama. Here I also illuminated a small bush / tree in white.

Panorama 2

Third panorama. Here I replaced the battery for the front red tree with the battery of the white LEDs. Now it lights up red at least properly.

Panorama 3

For the fourth panorama I then removed the batteries from the red tree on the back right and used them for the white LEDs. So far, I like the overall picture the best. (But it would be nice if the tree on the right also glowed red ...)

Panorama 4

A few more photos of the night

illuminated row of trees

I got two LensBalls for a birthday from two great friends (60 mm and 90 mm). The 90mm LensBall was used for the first time this night. Here is my favorite:

However, there is still room for improvement here. The lens ball would have to be placed higher so that I can easily take pictures from below. Then you would see more sky and less meadow in the ball. Unfortunately, my equipment is still somewhat limited here. I had already installed the camera as low as possible on my tripod (extra-short legs and maximum spread). Well, the main thing is that the dragon looks good. :-)

Here is a photo of the row of trees from this low perspective.

Finally, an overview of the overall situation. Since this photo is taken from the other side, the trees here do not shine so beautifully. They are only illuminated from one side.

LED lighting

I have now soldered the LEDs to pin headers so that they always have good contact with the socket headers. Since the LED legs are thinner than the pins of the pin headers, there were constant loose contacts during the last attempt. This has now been fixed. The shrink tube pieces ensure that less stray light e.g. the blades of grass illuminate in the area. But that was only provisional now. Actually, I want to install LED holders here. I don't have these yet.

LED-Module current LED module

So far I've made 14 of these LED modules. In addition, two boxes from old shipping boxes. Packed in it, the modules can be easily transported in a backpack.
