Abstract: A grille lighting system includes a light emitting lamp that includes one or more walls defining an inner space isolated from outside, a light emitting material disposed in the inner space and configured to emit light when the light emitting material contacts air, and a shutter disposed on the one or more walls, wherein the shutter is configured to be opened to allow introduction of outside air to the inner space from outside and further configured to be closed to block introduction of outside air to the inner space. The system further includes a controller configured to control operation of the shutter and cause the shutter to be opened and closed such that when the shutter is opened, the outside air is introduced to contact the light emitting material, which causes the light emitting material to emit light.
