    • A moveable or relocatable structure for providing an optical effect includes casing and an apparatus for providing an optical effect mounted in the casing. The apparatus is preferably a flame effect fire. The apparatus is mounted in an aperture of the casing and a gap is defined between the apparatus and the casing front wall to define an air flow path for entry of air into the apparatus, for example to supply a heater. A frame is provided in front of the apparatus to shield the gap from the normal view of a user. The frame is spaced forwardly from the apparatus and the casing front wall to allow an air flow path between the frame and the casing front wall which communicates with the gap defined between the apparatus and the casing front wall.
    • 用于提供光学效果的可移动或可重定位的结构包括壳体和用于提供安装在壳体中的光学效应的装置。 该装置优选是火焰效果火。 该装置安装在壳体的孔中,并且在装置和壳体前壁之间限定间隙以限定用于进入装置的空气的空气流动路径,例如供应加热器。 在设备前面设置一个框架,以将间隙与用户的正常视图进行屏蔽。 框架与设备和壳体前壁向前间隔开,以允许框架和壳体前壁之间的空气流动路径与与设备和壳体前壁之间限定的间隙连通。
