LED for Nikon Labophot Dual View (Teaching) head

#1 Post by cmug » Wed Mar 25, 2020 7:32 am

Here my upgrade for a Nikon Labophot Dual View (Teaching) head
The original lamp for the arrow pointer was missing so I made a LED lamp myself.
Anyone who can work with a lathe can make it
Here a few building tips
Start with an aluminum cylinder from 18 mm length and a diameter from 17 mm.
Drill a 11.0 mm hole and then a thread from M12 x1.5
Make 2 grooves for O-rings. Check whether the size is correct for proper clamping
Place a piece of acrylic round at the front, diameter 17 mm and 3 mm thick.
Place a PG7 cord strain relief . And adhesive on the acrylic round at the top.
As a lamp I used IKEA USB lamp of 5V 0.3 Watt

Nice to have and be able to use a lathe.

Am curious as to why you included an acrylic washer between the LED and the aluminum rod, given that in all the designs I have seen the use of an aluminum rod is to dissipate heat.
Zeiss Standard WL (somewhat fashion challenged) & Wild M8
Olympus E-P2 (Micro Four Thirds Camera)

You are absolutely right. Using the aluminum can here as a heat sink is much better.
The reason I didn't do it is that there was no heat sink in the IKEA LED either. So it seemed unnecessary to me
I bought the LED for around € 3.- So that's low.
You can find the LED I used easy if you Google for: JANSJÖ Led-lamp USB

If you have not an lathe just put the original IKEA lamp in the opening (it fits nearly, use some black duck tape for the a finish)

Soon I will report about my Wild M20 microscope with conversion from 6V / 15 Watt bulb to LED. There I did use aluminum as a heat sink
