Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a lighting device, and provides a lighting device that allows lighting effects such as direct lighting, side lighting, and indirect lighting to be freely and steplessly obtained with one light source section. The invention relates to lighting equipment.

[Conventional technology]

Conventionally, two lighting devices capable of direct lighting, indirect lighting, and side lighting have been proposed, such as the one described in Japanese Patent Publication No. 8881/1981. In this device, the first lighting section mainly provides direct illumination and the second lighting section provides indirect illumination. and the second lighting section, the structure is fixed in common between the first lighting section and the second lighting section.

Each light source of the second lighting section was selectively turned on to obtain the desired lighting effect.

[Problem to be solved by the invention]

In this way, the conventional method of obtaining direct lighting and indirect lighting using individual lighting equipment was to have a dedicated structure for each lighting section, so if you wanted to obtain the same effect with the same light quality,
Each had to have their own dedicated lighting section. Furthermore, since the light source and the reflecting plate are fixed, the irradiation direction is limited. For this reason, it has been impossible to freely change the irradiation direction and obtain a desired lighting effect, for example, even if one wanted to obtain illumination mainly from side illumination, it was not possible.

This invention was made to solve the above-mentioned problems, and provides a lighting fixture that can steplessly and freely provide illumination in irradiation directions such as direct illumination, side illumination, and indirect illumination with one light source. The purpose is to

[Means for solving problems]

The lighting device of the present invention has a reflective shade that is rotatably configured to rotate around the lamp around the axis of the lamp, and a transparent part that is integrally configured over the entire length of the lamp. By providing a cover body and transmitting the rotational force from the drive source that rotates the cover body via the drive transmission unit, the direction of the light-transmitting part can be freely changed by rotating the cover body, allowing direct lighting, side In addition, lighting effects such as indirect lighting can be obtained steplessly.

[Effect]

The lighting equipment of the present invention has a structure in which the cover body, which integrally constitutes the reflective shade and the transparent part, rotates around the lamp, so the irradiation direction is not limited and can be easily set to the desired irradiation direction. can be changed to easily obtain the desired lighting effect.
