Triangular USB table lamp with teddy bear theme

Beschreibung

I bring another night lamp with triangular shape , the parts are compatible with the other models that I have uploaded like this one. It's the LED that gives the color to the lamp!!! This time only the part "2-Bear-Background-Bear.stl" is printed in two colors, the rest is one color. For the PINK LED I put the following 1W(pack of 10LEDS) by Aliexpress: https://es.aliexpress.com/item/32986117559.html As it is USB powered you must lower the voltage from 5v from the USB to the 3.3v of the LED or it will burn out the LED. To lower the voltage I used two different ways, the first (and that uses 100% of LED capacity) is with a voltage regulator to 3.3v, although this way makes the LED very hot, and if you can get to overheat the plastic as to modify the lamp. The regulator I bought is the following: https://es.aliexpress.com/item/1005005772146981.html The other way to lower the voltage is to use a resistor in series with the LED, I used a 1/2W of 10ohm ~1% value, so the LED consumes between 0.8 and 0.9W of its capacity, so its luminosity decreases a little, but the temperature drops quite a bit.
