Replacing the bulb
An LED chip, fixed by a socket and thermal paste in the spotlight, serves as the light source. After removing the chip, it
is necessary to remove the residual thermal paste and apply new thermal paste.
How to proceed:
J
Use a leather or textile cloth (for a be
tter grip) to hold the front cap and unscrew it counter
-clockwise.
Gently tap to remove the protection lens, O-ring and reflector from the lamp.
Undo the small screws on the LED chip holder and lift the chip holder up. Then remove the LED chip itself from the
bottom of the housing.
– When lifting up the chip holder, take particular care not to damage the electrical connection.
Apply a small amount of new thermal paste to the bottom of the housing and spread it using a credit card or similar.
The layer of paste on the bottom of the housing must be large enough to cover the entire bottom surface of the new
LED chip when it is in position.
Align the LED chip such that its plus and minus pole make contact with the plus and minus pole of the chip holder.
Assemble the spotlight in the reverse order.
Use the O-ring supplied with the LED chip.
– Ensure that the O-ring sealing surfaces are clean.
Screw on the front cap clockwise as far as possible.
