Assuming you're talking about this front panel or similar (if not, please specify)
Load display is the bar graph on the left hand side with the image of a computer below it. This lights up accordingly to give the user a visual representation of the current load percentage on the UPS. Thus, the user knows if all of the LEDs are lit, the UPS load is very high and should be reduced. If no LEDs are lit, the load is very low. As outlined in the UPS user's guide, each LED represents a particular load percentage. i.e. one LED lit may represent ~15% of load. The user's guide should note this.
Online LED - this indicates the UPS is operating off of mains/utility power. You reference "double conversion" so I assume you're looking at a Smart UPS RT or similar. This means the UPS is not operating on battery power input power but if input power is lost, the UPS would go to battery power.
