MEMBER FOR CONTROLLING LUMINOUS FLUX, LIGHT-EMITTING DEVICE, AND ILLUMINATION DEVICE |
摘要 |
A member for controlling luminous flux (100) has an incidence surface (110) and an emitting surface (120). The incidence surface (110) is a pyramidal surface having a recessed shape relative to the bottom of the member for controlling luminous flux (100), and having rounded borders between the individual facets. The horizontal cross-section of the incidence surface (110) is substantially similar in shape to that of an n-hedral irradiated surface (410). In the horizontal cross-section of the emitting surface (120), each of the straight lines connecting together adjacent angles of the n angles that correspond to the n angles of the irradiated surface (410) is substantially parallel to the side that corresponds to the horizontal cross-section of the incidence surface (110). The horizontal cross-section of the emitting surface (120) is the same as the n-hedron formed by the straight lines in the cross section, or fits inside the n-hedron. |
