Welcome to back boss in the video this time
we try to fix the floodlights
are exposed to rain water infiltration
and it has a crusty and total death
how to open it we heat on a hotplate
to open it we heat a few minutes
if I have my Preheat 15 minutes on a hotplate
and then we congkel for the front of
the front, the
glass is only sealed with the aluminum body,
so to open it, just heat it up
and we pry it out
please be careful because the material for the cover is glass, not acrylic, the
condition for the led pcb is very pathetic,
especially in the distribution line power
This IC is for what I don't know
so because the serial code is not visible
So I don't understand what it does?
to treat my curiosity, let
's just check the LED lights that are connected in series,
we use a power supply set to 6 volts DC,
we check one by one it looks like the leds are OK,
then we check using 16 VDC or 16 volt DC
, I measure 3 lights at once This
LED to lift 4 LED lights is not strong
but if to lift 3 LED lights 16 volt DC is STRONG,
so my prediction is that this LED light works at 3-5 volts or the USB voltage
in this PCB has 42 LEDs. For example, multiply the
required voltage around 240 -250 volt DC
if something is wrong, please correct it via comments, boss,
to save time, let's just replace it with a COB
LED lamp or an HPL LED lamp that supports 220 AC, the
price is relatively CHEAP, 20-30 thousand rupiah, some Rp. 25,000
in this video, I use it 50 watt COB LED lamp that supports 220 V AC.
There are two COB LED lights, white and warm white
, the first one I tested
, this one is warm white or yellow
for attaching cob LED lights. to the body so that the heat from the LED COB is evenly distributed
I use DIY glue
so my glue is getting hotter the stickier it is the drier
if the COB LED heats up unevenly to the body it
will easily cause damage to the LED lights
the next step is soldering or connecting the cables to the LED lights The COB is
because there are some parts of this cable that are peeling or to protect the parts
that are subject to voltage, I smear it with UV glue
or this is often used by HP technicians to protect jumpers
to dry these UV lamps, they can be dried in direct sunlight
or we use UV lamps
without UV lamp this glue will not dry
even a day will not dry
Knowledge is limited Your lifespan is limited
