Abstract

The present invention relates to an area light source illumination device for elevator car, belonging to the field of elevator technology. It is characterized by that it includes at least one or several LED modules mounted on the car top and/or car wall, said LED light-emitting modules can be driven by drive circuit, and can be used for producing an illumination light source with large-area single color or mixed variable color by means of transmission body or light-mixing body. Said invention also can be used in other public places, such as underground railroad station, underground tunnel and advertising board, etc.

Description

technical field [0001] The invention relates to a surface light source lighting device for an elevator car, which belongs to the category of elevators. technical background [0002] The current elevator car lighting still uses traditional incandescent lamps, fluorescent lamps, halogen lamps and downlights as basic light sources. In order to beautify the elevator car, people can only improve the decoration of the car roof. For example, some point-type or tubular transparent holes are selectively set on the car roof, which can only be partially illuminated. In the case of obtaining the same illuminance of the car, the light intensity on the surface of the light source is relatively large, and the light directly shines on the human eyes, which will make the human eyes very uncomfortable, and even cause damage to the human eyes in severe cases. Moreover, it is difficult to achieve uniform lighting in the car by using ordinary lighting methods. Even if frosted glass or plexigl...
