Adjustable LED base

Adjustable LED base Many people have asked me how I light my lampshades. I just use a red, green and blue LED in offset from each other. My old LED bases are made from wood and are very simple in design. See picture. But now I have made one that can be printed. I also took the liberty to make the distance between the LED’s adjustable. The distance between them can be adjusted by turning the outer ring of the base. The white adjustable one in the pictures has 3W LED’s they come with their own heatsink. They work well, but they get really hot. They must be able to radiate their heat. So I recommend making a hole into the base of your spiral vase mode lamp shade. Otherwise they will melt the plastic. If you are using the 1W LED’s and they have no heatsink, you have to glue them to an aluminum plate with thermal glue. In the picture of the wooden base you can see an example. Most of the photos of my lampshades are with a base that includes 1W LED’s. Then there is the problem that there are a lot of different LED’s you can buy and they are not all the same in voltage and current they use. So the resistors used may vary in resistance and voltage. So it’s very important to use the right resistor. The value of this resistor is defined by the voltage of you power supply, the voltage of the LED and the current the LED will draw. In my case I use an USB power adapter 2.1A and thus 5V. Most RED power LED’s operate at a voltage up to 2.3V Most GREEN and BLUE power LED’s operate at a…
