<p>An illuminator is disposed in an air path of a ventilation blower disposed above the ceiling of an elevator cage. An illumination shielding device is disposed below the illuminator and also in the air path. The illumination shielding device includes a plurality of spaced apart parallel rectangular plates, where the lower portions of the plates are inclined toward the elevator cage sidewalls. One or more such combinations of illuminator and illumination shielding device can be used in an elevator cage. Preferably, illuminators and illumination shielding devices are disposed at corners of the elevator cage ceiling, in order to maximize elevator cage capacity. A reflective plate can be mounted to the elevator cage ceiling.</p> |
