    Control ANY Light With Philips Hue

    Hi William-George, I guess you just had some BC107 lying around .. ;-) I prefer to use SMD power fets and attach them to the daughterboard. This is nice solution for the PT4115 GU5.3 lamps I have .. anyway I've attached the picture of my Hue part number and looks like identical to yours but the last digit 0== E27? and 1==B22? .. so everyone look for the SILVER text and the Model:929001137xB ...

    Control ANY Light With Philips Hue

    HI CaiusTitus, I saw your private mail .. same as this so thought I'd reply so others can read.Regards getting the correct B22 (only UK market) .. this is very much unpredicatable. I bought 4x B2 so far a twin pack from Amazon UK and Argos UK. Both sets have the daughterboard. I've have to check the Hue part numbers later but were bought in last 5 months. I've only opened 1 of the euro E27's and this had the large board that 0xFred shows. I guess it depends which country you are in .. will change outcome.The wiring is easy and you need 3 connections. (1) 4v-25v DC supply (2) Ground (3) PWM 3.3v.The main issue is that this 3.3v signal is quite low and not enough for driving the power fet that W-G used, and output will be inverted. This looks like an FDH5500 ( https://www.ebay.co.uk/sch/...

This looks like an FDH5500 ( https://www.ebay.co.uk/sch/i.html?_nkw=fdh5500 ) but not 100% sure. There are many power fet's you can use, just depends on your current / voltage loads and with / without heatsink. I used a IRF540N ( https://www.ebay.co.uk/sch/i.html?_nkw=fdh5500 ) in my tiny lamp control box shown below.As for NPN, then this looks like BC107 or something like that. It's too big for me so I use a small fet and mounted on the back of the daughterboard (see description below).

    Hi Trev1969, regards the ON/OFF on the daughterboard, to be honest I haven't looked to see where it is .. as I was only interested in the PWM signal. The SSR you mention may not work from 3.3v as it may not turn the SSR LED fully on. You'd need some fet to boost the 3.3v signal with pullup to 5v-12v etc. Oh, and pushing up the supply voltage to the daughterboard is no good as the ULDO drops it back to 3.3v internally.

    Hi Tim2309, depends which hue pcb you have. If it's the same as Fred mentions there maybe the same small FET as on the white hue PCB I use. Anyway looking at the LDD data sheet it looks almost identical to the PT4115 dimmers I've been using, so you only need an open drain FET to drive this LDD signal .. either the one on the board or an additional one in parallel!

    Control ANY Light With Philips Hue

    Hi OleU1. Wow sorry I didn't see your imediate response, just checked back and seen your long reply. Danke!Anyway I've had much the same ideas as you and of course you are right regards the non-standard colours. For me I can't bear to pay for e27 colour hue bulb to cut up and try, when I've got a Philips lightstrip, I'll eventually but a 2nd and use the controller for my RGBcW+wW strips and add the 2m of redundant "strip" to my original lightstrip (save any colour conflicts in one room).In the meantime I've been slowly adding more Hue Zigbee boards to my various non standard LED in the house. I have a high power FET switching version and low power version to control the many GU5.3 PT4115 dimmable lamps. I have lots of these lamps I bought cheap like you they have the PT4115 c...

I have a high power FET switching version and low power version to control the many GU5.3 PT4115 dimmable lamps. I have lots of these lamps I bought cheap like you they have the PT4115 contollers inside and very very easy to dim with an open drain FET. http://www.simonsdialogs.com/2017/09/jansjo-readi...All I did was add a small 2N7002 to the Zigbee board and switch many of these PT4115 .. easy!When I have time, the next major issue is time shifting the PWM duty cycle. The current PWM duty goes from 4% to 100%, because this is tuned to the LED "current" controller. The arduino solution is too big for me, and I'm thinking of an 8 pin SOIC PIC device, this should fit quite well to the back of the Zigbee hue board. http://www.microchip.com/wwwproducts/en/PIC16F153... This will allow me to adjust the non-linearity of the 1%-100% APK control to match a better visible control curve.BTW the picture is of an EMPTY hue bulb (i.e. no zigbee board) and it now lives in the small black box with a power FET. It switches 5/6A easily so not quite as powerful as William-George's, but in a tiny box!

    Control ANY Light With Philips Hue

    Hi OleU1 .. I like your PDF and RGBW MOSFET controller! I tried using the Philips lightstrip+ controller which works perfectly with my RGBcW+wW strips. But decided that I need to find a cheaper solution. Trying the color E27 hue bulb could be good, but am concerned they use non standard colors so PWM levels will be a little wrong. At the moment I've rigged up one white hue zigbee controller just to dim my cW+wW arrays, this works really well. I can swap this out once I've got a full RGBcW+wW solution sorted.As for the GU5.3, these still have some active dimmer controller inside, and will conflict with the 1khz? Tradfri control. I've given up with these DC dimming bulbs and remove all these active controllers from the led bulbs now.
