Sir.
I want to make high power led ON/OFF by an IR sensor interfaced with 89s52.
how to do that? I know interfacing normal led but i need info on high power led.
 

Here you have explanation how to :

Relay interface to MCS 51 family MCU (like 89S52)

DNA TECHNOLOGY - Interfacing Relay to Microcontroller


You can use the output transistor as power led driver too
Check that transistor Ic is high enought to drive your load.
or connect an additional transistor stage, for increasing output current.
For higher load currents use relay contact, it gives galvanic isolation for
load / MCU circuits.

Thank you sir.
