4. How to do the Lamp
replacement in a projector? |
|
|
If you have the option to buy a bare
lamp for your projector , you will need a basic technical
knowledge to replace it. By buying just the lamp you do not
get the 'housing' around the lamp and changing it can be a
difficult job, often resulting in damage or difficult to put
all the parts back to the original state. We highly recommend
you send the old lamp module to our local service centre or
distributor if you do not already have extensive technical
knowledge of projectors and/or electrical hardware.

5. What are tips of
extending the lifetime of a lamp? |
|
|
• |
|
Don't keep the projector in
a closed chamber without ventilation, or any circumstance that
makes the projector to become overheated. Excessive heat will
cause the projector a shorter lifetime. |
• |
|
Operate your projector in a clean and
less dust environment. Use air cleaning machine in the room is
also helpful. |
• |
|
Clean air filters regularly. Utilize
the "economy mode" if it is available with your projector
model in the environment. |
• |
|
Turn off the projector to ensure that
the projector has had an adequate cool-down period as stated
in the user manual. |
• |
|
Turn on must be at least 5 minutes
apart if the projector is just off. |
• |
|
Don't shake or vibrate the projector
when the machine is on, especially when the projector is in
the cooling down. The bulb is fragile when the machine is on
and cooling down period. |
• |
|
Lamps are fragile in certain
circumstance. When changing a Lamp, never touch the actual
bulb (or burner) itself. The oils on your fingers may stay on
the bulb causing a heating spot. This may cause it to
explode or burn out faster when the overhead projector is
on. Use a cloth or a tissue to handle the bulb when
installing it in the overhead projector.
