Claims (11)
該発光素子から照射光軸に対して所定角度より小さい角度で発せられた光を射出する第1の射出面、前記発光素子から前記照射光軸に対して前記所定角度より大きい角度で発せられた光を反射する反射面、および前記第1の射出面の周囲に形成され、前記反射面で反射した光を射出する第2の射出面を有する光学部材とを有し、
前記第2の射出面は、前記照射光軸から最も離れた部分が、該照射光軸に最も近い部分よりも照射光軸方向における前記発光素子とは反対方向に突出した形状を有することを特徴とする発光装置。 A light emitting element;
A first emission surface for emitting light emitted from the light emitting element at an angle smaller than a predetermined angle with respect to the irradiation optical axis, and emitted from the light emitting element at an angle larger than the predetermined angle with respect to the irradiation optical axis A reflection surface that reflects light, and an optical member that is formed around the first emission surface and has a second emission surface that emits light reflected by the reflection surface;
The second emission surface has a shape in which a portion farthest from the irradiation optical axis protrudes in a direction opposite to the light emitting element in the irradiation optical axis direction than a portion closest to the irradiation optical axis. A light emitting device.
入射光軸が通るように形成され、入射した光を前記受光素子に向かわせる第1の入射面、該第1の入射面の周囲に形成された第2の入射面、および前記第2の入射面から入射した光を前記受光素子に向けて反射する反射面を有する光学部材とを有し、
前記第2の入射面は、前記入射光軸から最も離れた部分が、該入射光軸に最も近い部分よりも入射光軸方向における前記受光素子とは反対方向に突出した形状を有することを特徴とする受光装置。 A light receiving element;
A first incident surface formed so as to pass an incident optical axis and directing incident light to the light receiving element; a second incident surface formed around the first incident surface; and the second incident surface An optical member having a reflection surface that reflects light incident from the surface toward the light receiving element;
The second incident surface has a shape in which a portion farthest from the incident optical axis protrudes in a direction opposite to the light receiving element in the incident optical axis direction than a portion closest to the incident optical axis. The light receiving device.
