Small fluorescent lamps by YASUHIRO from japan

Fluorescent lamp has been changed. Such as the lamp size is slender and the light source is to LED lamp. I thought the relationship between of shade and fluorescent lamps.　The lamp size is slender so the shad is smaller. LED lamps are a surface light source, the directivity is strong(＜180°). The shade loses the function of the reflection of light. The shade will be smaller.
We feel far what we look smaller. The shade lost function of reflection looks smaller, and a ceiling is far from the shade.
We feel more distant the ceiling. we feel a space on a head stretched.
