IR transmitter module power

I've bought one of these sets of IR transmitter and receiver modules.
I have the transmitter module connected to an ESP8266 dev board and am sending codes to my LG TV with success.

But i am finding that my TV only detects the codes sent by the module if the module is within about 3 feet of the TV.
I have the sensor connected to the dev board's 5v pin, not the 3.3v pin.

I assumed this transmitter module contains some type of driver circuitry to ensure the diode gets plenty of milliamps but now am wondering if that is true.

This pic of the transmitter module shows 3 SMD components and the IR diode.
Can anyone tell me whether this is a driver circuit that allows plenty of power to the IR diode?

No, its passive with 220 ohm series resistor for the IR emitter and a 1k series resistor for the little LED.
That means less than 20mA for the emitter. Decent emitters can handle 100mA with 1A peaks, so I suspect
the emitter is a boring ordinary IR emitter, which are cheaper.

For high power IR emitter you'd normally expect a series resistor of a few ohms, a transistor or MOSFET
driver, and a suitably large decoupling capacitor.

Thanks for confirming what i suspected.
I'll Google for a suitable active driver cicuit.

You also need to make sure that the IR modulation frequency matches that of the TV remote. Usually 38 kHz, but often 40 or 50 kHz.

I have used [something like this](http://"I have used Infrared 5mm Water Clear LED - 15deg - 1100mCd – Kitronik Ltd") to send the signal for remotes that use the typical protocols with 38Khz, you can find them as Infrared 5mm Water Clear LED -1100mCd. Also some IR senders described as "5mm INFRARED EMITTING DIODE BLUE-TRA 940nm" may work.

These are cheap, and you can use them as you need in a breadboard or your own setup.

Do you use any active driver circuit or just power them directly from a GPIO pin?

I've just ordered 4 Super-bright 5mm IR LEDs and an N-channel power MOSFET and hope these will enable me to build my 'smart remote'.
