Your remote was designed to use a particular IR LED on its output. If you
were to put in a stronger LED design of the driver circuits for the LED
would have to also be modified to be able to supply the new device. In the
end, I would think this to not be feasible.

Also, there are most likely more efficient IR LED's around, but you would
have to first work out the specs of the origional one, and then search out
for an equivlent replacement that are more efficient. This may avoid any
necessary modifications.

Considering that your TV and remote is very old, you should be considering a
new system, rather than trying to modify it. In both the TV and remote, it
is very probable that some of the components have drifted slightly out of
specs over the years.

I have seen in some places that sell TV's and sound systems, a gadget that
is called a remote control repeater. It is a unit that sees the IR from the
user's remote control, and repeats it on its output. You only have to face
the repeater in the direction where you want the IR beam to go. On the
opposite side, it has a receiver for the user's remote. This also works very
well under the proper conditions.

Apart from cleaning my TV remote control (see other thread) I
would like to put in a more powerful infrared LED

The remote control is about 10 to 15 years old. The spec is
below. Note that I am in the UK.

I would guess I can get an LED nowadays which draws the same power
as the orignal LED but with a noticeably better light output.


Q. What is the spec of the infrared LED I need to get? Here is
one LED I came across. Is it ok? http://tinyurl.com/d3qcp
And here is a list of half a dozen other infrared diodes which I
can get relatively easily: http://tinyurl.com/8heeq

Q. Maybe I can put in a LED which actually draws a bit more power
than the original one?

Q. Is the way to do it to put two LEDS in parallel?

COuld anyone kindly advise me. Thanks.
