Abstract:
A light emitting device comprising:a disc-like globe including a light permeable first wall, a second wall disposed opposite said first wall, and a circumferential side wall disposed between said first and second walls, and a plurality of light source devices secured within said globe and arranged along a peripheral portion thereof, each of said light source devices comprising: a light-permeable cap having opposing top and bottom surfaces, opposing first and second surfaces located between said top and bottom surfaces, opposing third and fourth surfaces located between said top and bottom surfaces and between said first and second surfaces, said bottom surface having a concave portion extending toward said top surface; and a light emitting diode accommodated and secured in said concave portion so that a part of light emitted from said diode is projected toward said top surface; said top surface being a flat surface oriented at such an angle that the light projected toward said top surface is reflected thereon and is redirected toward said first surface, each of said light source devices being disposed so that a light from said first surface of each of said light source devices is projected outwardly from said globe through said light-permeable first wall.
