I bought another of the PIR LED lamps in my local bayonet cap base style to see if the circuitry was similar to the others I'd looked at.
It's different, but similar. And slightly bizarre that they've felt the need to scrub the number off what is clearly a BISS0001 PIR detector chip.
The listing I bought this lamp from was:-

Hey BG, how are you doing? Trust all is going well, someday I'd like to learn how to reverse engineer things the way that you are able & believe me I have tried but just starting out in electronics it just does not make any sense to me as to where to start & end & all of that. I've tried on a simple, well I thought a simple enough circuit board with 5 Blue LED's, two transistors & 3 resistors with a J1 plug, I think it's called for the power hook up & oh yeah the mic. on the board to flash the LED's with enough noise or music & I'm just unable to figure out even with the schematic as to how to look at the board & figure it out how to reverse that onto paper as you do it, so any advise from an old pro would certainly be well appreciated my friend. I've worked on mainly in the last years of my career as a service tech. on Heat/Air/Refrigeration. Anything that was appliance related I'd work on & repair it so that's why I don't understand as to why I'm unable to figure this out when I've learned so many different things in my lifetime, about 60 now, yeah I know I'm an old buzzard. Sorry to ramble on, happens to me sometimes.
I'll never look at those lights the same way again. Laughed when I saw one at the shop the other day.
bigclivedotcom, just over a year ago you made a review of the Amecal ST-9927T that you had just bought, yet here you are using a ACMECaL ST-9905 instead. Did the old one break, or is this just an extra?
"That's a bit childish" 🙂
what happens on this PIR lamp if you sit on a desk and not move does it closes or there is some timer in it?
Love your videos, and really love that metal screwdriver! Where do you get it from please?
Interesting.
These lights are interesting, but scary to see the very frail wires connected to the mains!
Oh Clive, you know you just needed to have a set, 1 for each hand.
can you explain the zener diodes in parallel a little better? Is there an advantage to adding them vs the way other models do it? I realize they are done in parallel for current capacity, but I don't remember other bulbs having the diodes.
I haven't been through all the comments to see if anyone has suggested this – but is the design of the LED module (eg the use of a 1uF dropper) to provide adequate hold current for the triac that they use?
Thanks Clive. Great video as always. Do you know how long this one stays on before needing to be retriggered?
Thanks Clive, interesting breakdown of that lamp.
