Even if the light source 3 is provided, since the light source 3 is surrounded by the translucent frame 4 that refracts the path of the light from the light source 3 so as to be substantially parallel to the lower surface of the ceiling 1, the light shielding angle is increased to prevent glare. Can be prevented. Moreover, since the translucent frame 4 is formed in the prism shape so that the path of the light from the light source 3 is substantially parallel to the lower surface of the ceiling 1, the translucent frame 4 refracts the light. The light can illuminate the ceiling brightly.

The locking spring 12 is fitted into the opening 2 of the ceiling 1 from below.
It is fixed by. The light source 3 is formed by providing the lamp 11 in the translucent globe 15.
The light source 3 is mounted in the main body case 8 so that the lamp 11 thereof projects from the opening on the lower surface of the main body case 8 to the lower side of the ceiling 1. Further, a flange 13 is provided on the lower end edge of the main body case 8 so as to horizontally extend outward and is fixed to the lower surface of the flange 13 with a screw 14 so that the light transmitting frame 4 surrounds the light source 3. Is provided on the lower surface of the ceiling 1. The light-transmitting frame 4 is made of glass, transparent plastic, or the like in a ring shape, and light from the light source 3 is transmitted through the light-transmitting frame 4.
When the light is incident on and is transmitted through the light-transmitting frame, light is refracted so that the light travels substantially parallel to the lower surface of the ceiling 1, and the inner peripheral shape and the outer peripheral shape are formed to function as a prism (lens). Is done.

果も発揮されるものである。In the illumination device formed as described above, the lamp 1 of the light source 3 has an optical path indicated by an arrow in FIG.
When the light from 1 is incident on the translucent frame 4, the light travels substantially parallel to the lower surface of the ceiling 1. Therefore, the path a of the light passing through the translucent frame 4 and the lamp 11 of the light source 3 to the translucent frame 4 The light-shielding angle θ with respect to the path b between the light and the light directly entering the room without being incident on the room becomes a large angle substantially equal to the angle θ'between the path a of the light and the lower surface of the ceiling 1, which is uncomfortable. It is possible to prevent the occurrence of such glare. Further, when the light from the lamp 11 of the light source 3 is incident on the translucent frame 4 in this way, the light travels substantially parallel to the lower surface of the ceiling 1, so that the illumination of the ceiling part is performed by this light. By illuminating the ceiling brightly, you can feel the liveliness when you look inside the store from the outside. Moreover, since the translucent frame 4 is illuminated by the light source 3, an appropriate feeling of glittering is produced, and the effect of attracting customers to the store is also exhibited.

明することができるものである。As described above, according to the present invention, the light source is provided so as to project downward from the opening of the ceiling, and the translucent frame is attached to the lower surface of the ceiling so as to surround the light source, and the translucent frame is provided with the light from the light source. Since the path of is formed in the shape of a prism that refracts so as to be substantially parallel to the lower surface of the ceiling, even if a light source is provided so as to project downward from the opening in the ceiling, the light-shielding frame surrounding this light source will block the light-shielding angle. To prevent glare from occurring, and the light from the light source that enters the translucent frame travels almost parallel to the lower surface of the ceiling to illuminate the ceiling with this light. The ceiling can be illuminated brightly.
