Abstract
A device for resin coating is used for producing an LED package including an LED element covered with resin containing phosphor. In a state in which a trial coating materialis located by a clamp unit, a trial coating of resin applied to the trial coating materialis irradiated with excitation light and light emitted from the phosphor contained in the resin is measured by an emission characteristic measuring unit. A deviation of the measurement result of the emission characteristic measuring unit from a prescribed emission characteristic is determined, and then a proper amount of resin to be applied to the LED element is derived for actual production based on the deviation.
