Detailed Description

The detailed features and advantages of the present invention are described in detail in the detailed description, which is sufficient for anyone skilled in the art to understand the technical content of the present invention and to implement the present invention, and the related objects and advantages of the present invention can be easily understood by those skilled in the art from the description, the claims and the accompanying drawings disclosed in the present specification.

First, directional terms such as "upper", "lower", "inner", "outer", "lateral", and "longitudinal" are referred to herein with reference to the normal orientation of the aircraft cabin.

As a first aspect of the present invention, a passenger cabin passenger service unit is provided, see fig. 1a-1c, comprising a passenger cabin passenger service unit panel 1, a floodlight cover 2, a scene lighting source 3 and a closing cover 4. The passenger service unit panel in the passenger cabin is provided with at least one of a reading lamp, a reading lamp switch, a crew calling key and a safety belt indicating lamp, and other components capable of providing service for passengers can be additionally arranged according to actual requirements. The top of passenger cabin passenger service unit panel is installed the closing cap, can close including the main part electrical structure of each part of passenger cabin passenger service unit panel, and floodlight cover is installed in closing cap top and is regarded as the partly of passenger cabin passenger service unit. As shown in fig. 2, the floodlight is of a generally dome-shaped configuration so as to substantially surround the enclosure and the passenger service unit panels of the passenger cabin from above. In fig. 2, the floodlight cover has floodlight plate portions 5 having a step structure on both sides in its transverse direction (which coincides with the transverse direction of the aircraft interior cabin to be installed). Of course, the floodlight cover can also have floodlight panel portions on both sides in its longitudinal direction (which coincides with the longitudinal direction of the aircraft interior cabin to be installed), or both on both sides in its transverse and longitudinal directions. The scenic lighting source is mounted on top of the inside of the floodlight cover and is arranged to illuminate the floodlight portion, the illumination direction a preferably being arranged in a horizontal direction. A gap is arranged between the floodlight cover and the closed cover, a channel for light rays of the scene lighting light source to pass through is formed between the floodlight plate part, the closed cover and the passenger cabin passenger service unit panel, and the light rays of the scene lighting light source are transmitted in a diffuse reflection mode by utilizing the step difference structure of the floodlight plate part.
