Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an improvement of a recessed indirect lighting fixture for a ceiling surface, etc., which prevents direct projection light from a lamp from entering the eyes.

[Prior art]

Figures 1 and 2 show this type of conventional recessed indirect lighting equipment. The lamp 3 is supported via receivers 2a provided on the edges of the opening of the main body on both inner surfaces, and has gutter-like frames 3a on both outer edges for shielding the direct projection light from the lamp 2. This is a front light projection cover for an interior reflector 4 in which an opening edge 3b is brought into contact with a mounting surface A such as a ceiling surface. Therefore, when the light projection cover is installed, the lamp 2 cannot be viewed directly.
Further, the light emitted from the lamp 2 is configured to exit from the central opening 3c of the light projection cover 3 and illuminate the room.

However, due to the shape of the light projection cover and the mounting position of the interior lamp 2 covered by the gutter-like frame as described above, the projected light from the reflector plate 4 only exits downward from the opening 3c, and the light projected from the reflection plate 4 is directed downward from the mounting surface A. The problem was that the ceiling surface became dark because it could not illuminate the ceiling.

[Summary of the idea]

In order to eliminate these drawbacks, this invention creates a light projection window hole on both outer walls of each gutter-like frame provided in the light-transmitting cover along the opposing internal lamp, and the horizontal direction of the lamp coming out from this window hole is The projector illuminates the mounting surface with projected light, making the entire room brighter, including the ceiling surface.

[Example of idea]

FIG. 3 is a sectional view showing an embodiment of the recessed indirect lighting device of this invention. In the figure, the same or corresponding parts as those in FIG. 1 are designated by the same reference numerals. Front light projection cover 3 of interior reflector 4
The characteristic feature is that both outer walls of each gutter-like frame 3a are provided with window holes 5 for projecting light from the lamps 2 in the horizontal direction. Direct light passes through the window hole 5 and illuminates the surface to which it is attached, such as the ceiling surface.

[Effects of the invention] As described above, the recessed indirect lighting fixture of this invention has a horizontal light projection hole in the outer wall of the gutter-shaped frame that covers each lamp, so that the fixture body is not buried. Since the light from the interior lamp can be irradiated onto the installed surface, for example, the ceiling surface, the ceiling surface becomes brighter, which makes the entire room feel brighter.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) An interior reflector plate having a gutter-like frame on both outer edges thereof, which shields the direct projection light from a lamp, and with the opening edges on the outer periphery in contact with the surface to which it is attached. A recessed indirect lighting fixture, comprising a front light projection cover, and in both outer walls of each of the gutter-like frames, window holes are provided for horizontally projecting light from the interior lamps. (2) The recessed indirect lighting set forth in claim 1 of the utility model registration claim, in which an internal lamp covered by gutter-like frames on both outer edges of the light projection cover protrudes from the mounting surface of the fixture body. utensils.
