12 LED PIR IR Night Light Status-LED Brightness Fix

thingiverse

The 12 LED PIR Infrared Stick-On Wardrobe lights from Ali Express are handy. But the status LED's are so bright while charging, or topped-off, that they blind the light detecting photoresistor, causing the unit to not work in AUTO mode correctly. BigClive did a fantastic review/teardown of these. https://youtu.be/GSkzXqkWayg Their price has risen recently so they're not quite as great a deal, but they're still handy well-made lights ....except for the status-LED brightness issue while plugged in. This object fixes that. ...It shields the LED's and also tunnels the light away from the photoresistor so the status can still be seen. It's much nicer at night. And, by keeping it plugged in, the battery can stay charged and be ready to serve as emergency backup lighting. The product page can be found with this search: https://www.aliexpress.com/wholesale?catId=0&SearchText=12+LED+PIR NOTE: Print this in BLACK or a fully-opaque color Supports will be necessary under the LED and wire cavities. You'll need to carefully hand-follow the LED tunnels with a 1/16" drill bit - I just use the hex-shanked type by hand without a drill and with PLA, it cleans the hole out nicely. Just make sure you eyeball the different tunnel angles well before you start drilling each. Installation: Partially unscrew the LED circuit board. Insure the wire paths match the notches. Orient so large square hole goes over photoresistor and mounting holes match the channels. It only fits one way. Slide the back edge of the fix underneath the LED circuit board and pull it towards the LED board until it overlaps it a bit. Verify the sensor PCB mounting holes are centered with the fix's channels. Re-screw in the LED board screw. Put the translucent cover on the lamp first and then put the lip of the opaque cover in first to level it up before pressing down. You may have to hold it while you screw the first two screws in. This is such a random fix. Please let me know if anyone actually uses this! :D
