Giant DIY light 大型ライトを作りました!

2021-12-20 by David



The downstairs hall is edging closer to completion now, so it's time to deal with those old lights. It used to be a dyeing workshop and then a painting studio, so I guess the bright fluorescent strip lights were adequate task lighting, but they are getting on a bit and so tend to buzz, and they have quite high power usage (320W for eight of them). Worst of all, the light they give off is a white light, which makes the room feel cold. So it's time to change them out....

▲ まずは3Dソフトで形を作ってみました。大引きの位置によって、二つに分けます。3メートルの丸い形に作りたいですが、そんなに大きい丸がないので、30cmずつのレール式にします。


I started this project by designing a large 3 metre diameter chandelier, with 18 retro-style Edison bulbs hanging down around the circumference. I suppose it's more of a rail lighting system than a chandelier, but the lights will be fixed in place. I originally wanted to make this a perfect circle from something like wood, but couldn't find any easy of creating this on a budget.... so I decided to make it out of 30cm straight sections joined together to make something that is close to a true circle.

▲ 最初に全部3Dプリントでしたかったんですが、重かったです。その代わりにDIY店で見つけった鉄レールを30センチ部分に切りました。


I bought several 2m metal rails from the local DIY store. I think they are commonly used as lightweight but strong systems for suspended ceilings, but they suited my purposes well too. So I carefully cut 30 pieces of 30cm length using a cutting blade on my rotary saw. Easy peasy so far!

▲ 作業中で手を切らないように鑢で綺麗にしました。


I then smoothed off any sharp edges with a file, so as not to cut my fingers later on!

▲ 電気配線の穴を開いてから、艶なしの黒でスプレーをしました。


Half of the pieces needed holes drilled in them for wiring, and then I sprayed them all with a matt black spray paint.

▲ 各レール部分を接続するところには3Dプリンターで30個のジョイントをデザインしました。上の写真はすべてのパーツとなっています。多いでしょう?!エジソン電球18個、中国から来たソケット18個、そしてレトロっぽい配線も集めました。


I'd been slowly collecting the various bits I needed for this project, so now I had 18 LED bulbs plus 18 shiny brass sockets, and some retro-style black cabling to match them. The joints between each section of rail were created to fit them exactly, and 3D printed slowly in the preceding days.

▲ 電気スイッチが二つありますので、1個の配線を抜いてライトの作成が半分ずつにしました。まずは天井から下がるところを図ってボルトとナットプレートを入れました。そして、ちょっとずつ各30センチ部分を下がりました。




Time to start fitting the light system, by fixing nut plates to the ceiling at various points. Then I fitted in cut pieces of long bolt, and hanging some custom-made hooks. Then I slowly slid in the short sections of railing, and started to join them together.

▲ 電球を入れて、スイッチの配線につながりました。電球のソケットにも1個ずつのスイッチもありますので、結構便利です。部屋の雰囲気や目的によって光が調整できます。


The next step was to run some cabling on the topside of the rails, and add 9 sockets using the retro-style twist cable. Each of these brass sockets has a separate on/off switch, so it's possible to adjust the light levels to fit whatever you're doing that day.

▲ 最後にレールを平行しました。あっちこっちに接続ジョイントが下がったところもありましたので、細かいプラスチックリボンで天井に付けました。これで平行に調整できましたので、ライトの半分終わりました。


The last thing to be done was to even up the railing. At a few joints the railing has started to droop slightly, because there were only 5 attachment points along the 4 meter circumference, so I added a few extra supports using long zip ties and some extra bits and bobs! This made the whole thing fairly level and even, and worked well enough for me.

▲ 1週間後に残りの半分も同じ風に完成できました!いかがでしょうか?


A week later I went back and completed the second half of the light in the same manner, and at last I had a finished lighting system! The height of the bulbs has been carefully alternated between high and low, just to create some extra interest and give it a more 'crafty' feel.

▲ やっぱり電球色のほうがいいですね!部屋の雰囲気も完全に変わりました!


I absolutely love it! The whole room is now bright and warm, and somehow still super cosy. I think lightbulb-coloured bulbs are such a great improvement on the glaring white light of strips lights.... plus the power consumption is now halved, even with 18 of those bulbs!
