  • the openings 2033 are preferably evenly arranged along the rotation axis of the rotating disk 203, for example, they may be arranged symmetrically along the axis of the stator 201, or they may be arranged symmetrically along the center of the stator 201, and there is no specific limitation.
  • the limiting member 3 is detachably arranged on one of the lamp housing 1 and the lamp shade 2 and after the lamp shade 2 is installed on the lamp housing 1, it is abutted and limited against the other of the lamp housing 1 and the lamp shade 2 to prevent the lamp shade 2 from rotating relative to the lamp housing 1, thereby achieving an anti-slip effect, which is safer and more reliable during daily maintenance and replacement and repair operations on the lighting fixture.

Abstract

Ensemble lampe (10) et appareil d'éclairage (100). L'ensemble lampe (10) comprend un boîtier de lampe (1), un abat-jour (2) situé sur le côté inférieur du boîtier de lampe (1) et un élément de limitation (3). Une partie d'encliquetage est disposée sur l'un du boîtier de lampe (1) et de l'abat-jour (2), et une partie d'accouplement d'encliquetage est disposée sur l'autre du boîtier de lampe (1) et de l'abat-jour (2) ; l'abat-jour (2) peut tourner par rapport au boîtier de lampe (1) et est monté sur le boîtier de lampe (1) au moyen d'un encliquetage entre la partie d'encliquetage et la partie d'accouplement par encliquetage ; l'élément de limitation (3) est agencé de manière amovible sur l'un du boîtier de lampe (1) et de l'abat-jour (2), et vient en butée contre et limite l'autre du boîtier de lampe (1) et de l'abat-jour (2) après que l'abat-jour (2) est monté sur le boîtier de lampe (1) de manière à empêcher l'abat-jour (2) de tourner par rapport au boîtier de lampe (1). Par rapport à une structure de fixation commune, la structure de montage par encliquetage rotative de l'abat-jour (2) et du boîtier de lampe (1) est plus facile à démonter, à assembler et à entretenir. Après que l'abat-jour (2) est monté sur le boîtier de lampe (1), l'élément de limitation (3) peut venir en butée contre et limiter l'autre du boîtier de lampe (1) et de l'abat-jour (2) de manière à empêcher l'abat-jour (2) de tourner par rapport au boîtier de lampe (1). L'élément de limitation (3) peut empêcher un couvercle d'être libéré avec le boîtier de lampe (1) en raison d'une force externe de manière à obtenir un effet anti-prise, de sorte que des opérations de maintenance quotidienne et de remplacement et de réparation de la lampe sont plus sûres et plus fiables.
