Description

  The present invention relates to a ceiling-mounted LED lighting structure.

  With the practical application of white LEDs, various attempts have been made to use LEDs for indoor and outdoor lighting.

  However, since the light emitted from the light source of the LED has directivity, it may be a problem in the illumination using the LED that it is not a problem in the illumination with the fluorescent lamp.

  As one of such problems, according to a straight tube fluorescent lamp installed on a ceiling surface in a store or an office, light is emitted in all directions orthogonal to the longitudinal direction of the fluorescent lamp. Therefore, it is possible to illuminate a wide area indoors, but when the illumination by a group of LED light sources arranged in a straight line in the horizontal direction is installed on the ceiling, it is orthogonal to the line direction due to the directivity of each LED light source. Therefore, in the lighting design, it is necessary to determine the mounting position of the LED lighting on the ceiling surface at a specific position suitable for each property, However, if the layout of furniture such as desks and shelves is changed, there may be a problem that lighting suitable for the changed layout is not performed.

  In view of the above-described problems, the present invention can facilitate the design of the mounting position of the LED lighting mounted on the ceiling surface, and can be illuminated appropriately even if the layout is changed. An object of the present invention is to provide a ceiling-mounted LED lighting structure that can be used.

  The above-described problem is provided with a group of LED light sources for illumination arranged in a straight line in the horizontal direction, and the group of LED light sources can be rotated around an axis parallel to the line direction. This is solved by the ceiling-mounted LED illumination structure characterized in that the direction of light emission from the LED light source can be changed by turning (first invention).

  In this structure, the light emission direction from the LED light source can be changed by rotating the group of LED light sources around an axis parallel to the line direction. Even if the mounting position of the LED is about in relation to the way the room is illuminated, the group of LED light sources can be rotated around an axis parallel to the line direction during construction to make the room illuminated suitable for the room. Therefore, it is possible to easily design the mounting position of the LED lighting, and to change the layout in the room so that it is illuminated appropriately.

  In addition, the above problem is that one or a plurality of LED light sources for illumination is set as a set, and a plurality of sets are arranged in a straight line shape in the horizontal direction, and each set has an axis line parallel to the line direction. The ceiling-mounted type is characterized in that the radiation direction of the light from the LED light source can be changed in units of a pair by rotating. The LED lighting structure (second invention) can be similarly solved.

  In particular, in the structure of the second invention, each group constituting the line can be individually changed in the light emission direction, so that it is a straight line shape, and finer adjustments are made as necessary. It is possible to make the illumination more suitable for the room and the layout change in the room.

  Since the ceiling-mounted LED lighting structure of the present invention is as described above, the design of the mounting position of the LED lighting mounted on the ceiling surface can be facilitated, and it is suitable even if the layout is changed. It can be illuminated.
