Detailed Description

The present invention will be described in further detail with reference to the following detailed description and accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. Furthermore, the technical features mentioned in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 to 3, a modular structure of a reading lamp for an aircraft cabin is shown, and a modular design concept is adopted, so that assembly errors in a manufacturing process are greatly reduced, the manufacturing efficiency of products can be improved, and time and cost are saved in maintenance and rework of the products. Meanwhile, all modularized parts can be recycled, and the trial service life of the reading lamp in the civil aviation passenger cabin is greatly prolonged.

The reading lamp for the airplane passenger cabin comprises a general light source module 1 and a detachable locating surface ring 2.

The general light source module 1 is provided with a module housing 11, a light source PCB 12, a circuit control board 13, a reflection cup 14, a lens and the like.

The module housing 11 is composed of a housing upper part 111 and a housing lower part 112. The casing upper half 111 and the casing lower half 112 together define a casing inner space. The upper housing half 111 has heat dissipating structures (e.g., fins) that can act as a heat sink. The light source PCB 12 and the circuit control board 13 are accommodated in the housing built-in space. The light source PCB board 12 is fixed to the cover upper half 111 by screws. The bottom surface of the light source PCB 12 is provided with light source LEDs. The top surface of the light source PCB board 12 is in surface contact with the inner surface of the cover case upper half 111. Heat generated when the light source LED operates is conducted to the outside through the cover upper part 111. The housing upper half 111 is formed with a housing through-hole. The wires of the light source PCB 12 and/or the wires of the circuit control board 13 can be extended out from the casing through hole to be connected with an external power supply or an external controller.

The light source LED is provided with a reflector cup 14. The reflector cup 14 is fixed to the upper casing half 111 by a reflector fixing plate.

The detachable locating surface ring 2 has different model specifications. The universal module is selectively assembled with the detachable locating surface ring 2 of one model specification. Specifically, the detachable positioning surface ring 2 has a surface ring bottom wall 21 and a surface ring peripheral wall 22. The face ring bottom wall 21 serves as an appearance panel. The face surrounding wall 22 is formed with a coupling hole. The case lower half 112 is formed with a connected hole corresponding to the connecting hole. A connecting piece 23 is arranged between the connected hole and the connecting hole, so that the cover shell lower half part 112 is fixedly connected with the surface surrounding wall 22.
