Indirected illuminating system concurrently in charge of air exhausting pass of elevator

Abstract

Provided is a lighting system doubling as an air supply passage for an elevator, and capable of sending air discharged from the upper part of the elevator, and of preventing light emitted from a luminaire in the upper part from being directly radiated to a user. This lighting system is used for indirectly radiating light of each luminaire 40 such as a fluorescent lamp or an incandescent lamp in an elevator. The lighting system is installed below a vent hole 20 for sending air discharged from an air blower 10 installed on the upper part of the ceiling of the elevator to the inside of the elevator, and includes: an illumination shading appliance composed by arranging multiple long rectangular tilting plates 32 tilting toward a wall surface of the elevator as they approach the lower side; and the luminaire 40 installed between the illumination shading appliance and the ceiling so as to be shaded by the illumination shading appliance. The air discharged from the vent hole is supplied to the inside of the elevator by sequentially passing the luminaire and the illumination shading appliance; dust and the like are prevented from being accumulated on the illumination shading appliance by the air; and the light emitted from the luminaire is radiated toward the wall surface of the elevator through the tilting plates of the illumination shading appliance, whereby the illumination light is prevented from being directly radiated to the elevator user.

Description

technical field [0001] The present invention relates to an indirect lighting system which doubles as an elevator exhaust channel, especially an indirect lighting system which guides wind from the top of the elevator car while avoiding the strong light from the top from directly hitting passengers. Background technique [0002] Usually, the lighting inside the elevator car adopts direct lighting system, indirect lighting system or a combination of both. figure 1 The previous indirect lighting system is illustrated. exist figure 1 Among them, a light source 1 such as a fluorescent lamp, an incandescent lamp, etc. is fixed on the top of an elevator car, and a translucent shading plate 3 is placed under the light source. As shown in the figure, in most of the current elevators, the wind source 10 and the exhaust passage are placed at the upper corners of the elevator car respectively, so the airflow from the fan bypasses the light source and enters the interior of the elevator...
