As the title suggests, it was time again to build a dining table lamp for the living room. It should be a LED light, clear. In the relevant trade, however, there was not what we had imagined. Designer pieces are usually prohibitive … Most of these fixtures work with HighPower LEDs and moderate cooling. A further shortcoming of many luminaires: the LEDs only radiate in one direction downwards. As a result, the ceiling is dark, which reminds me of a poker table.
HetongDIY will show you how to make a table lamp and the materials are quite simple:
- Aluminum profiles
- LED-Flexband warmwhite
- Power supply / dimmer
- And a suitable holder
The latter is the biggest challenge for self-construction and is only possible to a limited extent professionally. In this respect, a finished module was purchased from a lighting manufacturer. More on that later. Here is the result:
The luminaire itself consists of 2 aluminum profiles placed on top of each other.These profiles have 3 grooves / covers for flex tape.Since the profile for the table is only 1m long, you can use 3m flex tape.To the top, only 2m flex tape was laid.This should be sufficient for indirect lighting.
The Flexband has 120 LEDs / m each with approx. 8lm.One has so a total of about 450 lumens of light output.Despite 14.4W / m (altogether 72W) I have only used a 60W power supply.The reason for this is of course the space and the measurement of the power consumption, which despite center feed is not more than 60W.Apart from this one will get the full performance rarely.As a dimmer, we use a desktop device, which controls the receiver in the housing by radio.There were no problems with the shielding through the metal housing.
The fixture was used by a luminaire to be purchased (WoFi fixtures). These can be found in the construction market. The height adjustment is done with a counterweight. Here I was lucky that I could remove 2 metal weights and then had almost perfect counterbalance. The mechanical construction was then still quite tight and somewhat difficult. For safety, ventilating holes were added. It fits everything just in the case.
The tension is transmitted over the wire ropes. Therefore, the two brackets on the luminaire had to be fixed in isolation. The laying of the cables and the assembly were tight, but ultimately everything fit as I had imagined. We are quite satisfied with the result.
