Problems solved by technology

However, this lampshade structure cannot completely eliminate the rib pattern phenomenon, and because the distance between the lampshade and the soft plate is enlarged, the thickness of the light box is large, the volume is large, and raw materials and electric energy are wasted, which is neither economical nor bea

Example Embodiment

[0021] As shown in Figures 1-4, the shading and reflecting device for guiding the light source distribution provided by the present invention is shown. In the drawings, the light source distribution in the guide light box is taken as an example to show the setting of the shading plate and the reflector. However, it can be understood that the present invention is also suitable for guiding the light distribution of general luminaires.

[0022] As shown in Figure 1, a plurality of parallel light tubes 2 are arranged in the width direction of the light box 1, a transparent or translucent screen support plate 7 is arranged in the display direction of the light box, and a reflector 5 is arranged behind the light tube 2, and the light tube faces the display A front light reflector 3 is arranged in the front of the lamp. On the front end of the lamp tube, a number of light tube side reflectors 4 are arranged on both sides of the lamp tube. The two side reflectors 4 can slide in front of t...

Abstract

The invention provides a colored glaze of an illuminator which comprises a lump pipe and a curl reflecting plate behind the lump pipe. It is characterized in that: the end part of the curl reflecting plate arranges lump pipe two sides reflecting sheet; it reflects the light from lump pipe and reflected by the curl reflecting plate to the remote place so that the light can evenly illuminate to the picture support plate.

Description

technical field [0001] The invention relates to a device for shading and reflecting light emitted by a lamp tube in an illuminator, in particular to a light-shielding and reflecting device for guiding the light from a lamp tube in a light box. Background technique [0002] A general interior lighting light box includes a box body, the picture is arranged in front of the box body, and several parallel light tubes are arranged in the box body. There is a certain gap between two adjacent light tubes, which will cause light vacancies. After turning on the light, there will be discontinuous and uneven light on the light box picture, that is, the common rib pattern phenomenon, which seriously affects the effect of the light box and the picture. [0003] In order to reduce the rib pattern phenomenon, it is generally necessary to install a soft plate in front of the light box, and increase the distance between the lampshade and the soft light plate to reduce the illuminance, thereby...
