1 x Nichia NC4U134 (365nm UV)

1 x selfmade / selfprogramed µcontroller to selsect each colour with one switch
1 x LED Strippe v4 for pwm and battery management
1 x 9 ampere buck for the 24 xp-g
1 x µbuck with 700mA for the red XR-C
1 x selfmade Buck with 700mA with two AMC7135 for the Nichia UV (extreme low drop)

and many other small parts as cable, duo led, glue, aluminium for the seank...

assambling the xp-g to the starst with a heatgun and solder paste

Some details:

switch is included at the poti. switch on/off/on changes mode.
modes are:

- white
- red
- uv
- white beacon

you can dim in every mode. run the light longer then two seconds and it will start from white mode again.
the driver consist one attiny13 that controll three n-chanel fet´s. they do not need any cooling, cause they only switch on and of (no pwm).

the battery management have different modes:
- green > all ok > voltage higher then 14,4 volts
- red > battery voltage lower then 14,4 volts
- red flashing > battery voltage lower then 13,6 volts
- shutdown if the voltage is lower then 11,2 volts

the ampere is a buck controller from pcb components. it can handle 9 ampere. it is testet till 11 ampere. dimming is done via pwm. it gets not very warm. i try to make some detail pictures of the controller stack. it looks not very good, cause there is not much space inside.

the poti knop is only temporary untill i get a adequate one.

Pricelisting in Euro without worktime:
310,- Body
20,- Aluminium for Heatsink
75,- XP-G
70,- XP-C + Stars + optics
113,- Nichia NC4U133 UV LED
30,- PCB Components LED Strippe
31,- PCB Components Ampere
14,- PCB Components µBuck
1,- Reflektor von DX für Nichia UV
56,- AW IMR Akkus
10,- small parts like µC programmer

How did you obtain the nichia UV led?

it takes me a couple of hours. but last i get it direct from nichia germany! end user can´t oder direct here in germany. a friend of mine have a computer hardware store so he tried to order. but they also do not sell the led to him. the statement from nichia: we sell the uv led not for resale. some mails later he gets an offer about one NC4U133B. it coast 113,- Euro. the nichia uv led is absolutely amazing and powerfully.

WOW! Fantastic build!!!
This might be the highest lumen hi-CRI build I've seen. Incorporating red AND UV is simply stunning. Really, really impressive.

I haven't found a source for the UV LED yet. A Google of the model number gave the Nichia site for the data sheets. The advertisers listed on the search page were no good. There are also data sheets for the older single die UV-LED that McGizmo posted almost 7 years ago now.

According to Nichia's web page, model #NC4U134 is a 385nm UV-LED. For someone looking for a UV light for Norland 61 or $100 bills, you need the 365nm LED #'s NC4U133 or NC4U133A. Darkzero said Norland was, "surface hard in less than a 5 sec count!" That was the older single die 365nm UV-LED.

The data sheets say both LED's are the same physical dimension, Vf and current limit. Nichia NC4U133 has a 950mW typical output and NC4U133A is rated 1,200mW. I skimmed though it and can't find any other difference. I wouldn't be surprised if NC4U133A is double the price of NC4U133.;)
