[Problem that the idea aims to solve]

However, the above-mentioned reading light emits light downward from above the seat. Because the distance from the light to the seat is long, the light is placed directly below the reading light. Provides illumination not only for those who require illumination, but also for those seated in the surrounding seats who do not require illumination. Sometimes it spread and hit me, making me feel uncomfortable. Especially when this lighting is unnecessary. When a person reclines his or her seat, the light from the reading lamp hits his or her face at a nearly right angle. Because of the brightness, I often experienced glare.

0004 According to the above-mentioned reading light installed in the seat, the above problem can be avoided, but The reading light turns on and generates heat right next to the shoulders of the person sitting in the seat, causing the person sitting in the seat to feel hot. There were times when I felt that way. Also, this reading light emits light from the front of the backrest towards the front. Because of the irradiation, it reflects off the windshield and rearview mirror, causing damage to long-distance bus drivers. They may enter your field of vision, causing glare and impairing the visibility of the front of the bus. there were.

[0005] The purpose of this invention is to solve the above problems and to illuminate only the hands of the seated person who need illumination. The light will not cause discomfort to those around you, and will not cause heat discomfort to those seated in need of illumination. There is no need to worry about light entering the driver's field of vision, especially in vehicles. Our goal is to provide a new seat reading light.
