Of course you can't use this is production code, but if you are playing around .. try this Undocumented hack

It uses :

private void setBrightness(int brightness) {
try {
  IHardwareService hardware = IHardwareService.Stub.asInterface(
   ServiceManager.getService("hardware"));
  if (hardware != null) {
    hardware.setScreenBacklight(brightness);
  }
 } catch (RemoteException doe) {          
  }        
 }

Remember that it uses this permission :
