Why decreasing the curing tip diameter does not lead to an increase in irradiance in dental light curing units?

Logically, using a smaller diameter light curing tip should increase the irradiance of an LCU. In reality when measured, an LCU unit with a smaller tip diameter will generate a nearly 5x decreased...
