Description

The disclosed embodiments relate to bathroom lighting devices.

In recent years, LEDs have come to be used as light sources for lighting devices, but compared to conventional incandescent lamps and fluorescent lamps, LEDs have strong directivity and narrow irradiation ranges. In order to solve this problem, there has been proposed a lighting fixture that distributes light in a plurality of directions other than the LED irradiation direction (see, for example, Patent Document 1).

JP 2010-192388 A

However, when the above-described technique is used, light is emitted in both vertical directions from the lighting fixture, so that the upper and lower surfaces of the lighting fixture transmit light. For this reason, for example, when a user enters a room without turning on the lighting in order to clean the bathroom during the daytime, when looking at the lighting equipment, external light coming in from the top surface of the lighting equipment will directly flow to the bottom surface. Since the shadow is removed, the shadow of the internal parts such as the LED substrate can be seen, resulting in a problem that the design of the lighting fixture is deteriorated when the lighting is off.

One aspect of the embodiments has been made in view of the above, and an object thereof is to provide a lighting device for a bathroom that can suppress deterioration in designability due to shadows of internal parts being visible.
