発光ダイオード2から放射された可視光は、透光性のグローブ5に入射し、グローブ5を透過して拡散シート6に入射する。 Visible light emitted from the light emitting diode 2 is incident on the globe 5 of the translucent, is incident on the diffusion sheet 6 passes through the globe 5. 拡散シート6に入射した可視光の一部は、拡散シート6を透過して外方に出射される。 Part of the visible light incident on the diffusion sheet 6 is emitted outwardly through the diffusion sheet 6. また、拡散シート6に入射した可視光のうち、酸化チタン(TiO )やシリカ(SiO )などの光拡散性微粒子に当たった可視光は、当該微粒子により乱反射される。 Further, of the visible light incident on the diffusion sheet 6, the visible light impinging on the light diffusing fine particles such as titanium oxide (TiO 2) and silica (SiO 2) is diffusely reflected by the particles. ここで、拡散シート6は、グローブ5の外表面5aに密着するように被着されていて、その形状は略半球状となっているので、前記乱反射の可視光がグローブ5の外表面5aの略全域に反射される。 Here, the diffusion sheet 6 is being applied so as to be in close contact with the outer surface 5a of the globe 5, since the shape has a substantially hemispherical shape, visible light of the diffused reflection of the outer surface 5a of the globe 5 It is reflected in the substantially entire region. こうして、複数個の発光ダイオード2から放射された可視光は、それぞれグローブ5の外表面5a側において拡散される。 Thus, the visible light emitted from the plurality of light emitting diode 2 is diffused on the outer surface 5a side of the globe 5, respectively. そして、外部からグローブ5を視認すると、グローブ5の外表面5aの略全域が明るく見え、当該全域が光っているように見える。 When viewing the globe 5 from the outside, looks bright substantially the entire area of ​​the outer surface 5a of the globe 5, it appears to the whole area glowing. これにより、グローブ5で略均一な輝度が得られる。 Thus, a substantially uniform luminance in the globe 5 is obtained. そして、拡散光は、グローブ5の外表面5aの略全域側から外方側に出射される。 The diffused light is emitted outward side from substantially the entire region side of the outer surface 5a of the globe 5.

このように、グローブ5で略均一な輝度が得られるので、グローブ5側から出射される発光ダイオード2からの放射光が人に眩しさや不快感を与えにくくすることができる。 Thus, since the substantially uniform luminance in the globe 5 is obtained, it is possible to light emitted from the light-emitting diode 2 which is emitted from the globe 5 side is less likely to give glare and discomfort to the person. そして、複数個の発光ダイオード2を備えるので、発光ダイオード2からの放射光の全光束が多くなって、グローブ5からの出射光により明るく照明することができる。 Since comprises a plurality of light emitting diodes 2, increasingly total flux of light emitted from the light-emitting diode 2 can be brightly illuminated by the light emitted from the globe 5.

そして、グローブ5で略均一な輝度を得るために、拡散シート6をグローブ5の外表面5aの略全域に被着する簡素な構成であるので、LED電球1を安価に形成することができる。 Then, in order to obtain a substantially uniform luminance in the globe 5, since a simple configuration depositing a diffusion sheet 6 in a substantially entire region of the outer surface 5a of the globe 5, the LED light bulb 1 can be formed inexpensively.
