摘要:
A light emitting apparatus (180) is supported by a second support supported by a first support laterally relative to the first support alongside an imaging apparatus (190), and emits light (300) to be detected by the imaging apparatus (190). The light emitting apparatus (180) includes a light source (120) that emits the light (300) and a lens (130) on which the light (300) emitted from the light source (120) is incident and that transmits the light (300) incident on the lens (130). The lens (130) includes a part provided with a dimmer (400) that at least partially reduces light (301) to be emitted to the first support out of the light (300) incident on the lens (130).
摘要:
To provide an illumination apparatus including an LED, a first lens unit provided above the LED and a cylindrical lens provided above the first lens unit, in which the first lens unit receives light from the LED and emits the light toward the cylindrical lens, and the cylindrical lens emits the light to the outside.
摘要:
An illumination apparatus (130), including: multiple LEDs (101); and a lens unit (103) that is placed correspondingly to the respective LEDs (101), wherein the lens unit (103) includes a transmission lens (104), a first total-reflection lens (105), and a second total-reflection lens (115), wherein an incidence surface and an emission surface of the transmission lens (104), as well as incidence surfaces, emission surfaces and total-reflection surfaces of the first total-reflection lens (105) and the second total-reflection lens (115) are two-axis anamorphic aspherical surfaces, a microlens array (116) is formed on at least one of the incidence surface and the emission surface of the transmission lens (104), a microlens array (116) is formed on at least one of the emission surfaces, the total-reflection surfaces and the incidence surfaces of the first total-reflection lens (105) and the second total-reflection lens (115), and the microlens arrays (116) each have a structure in which microlenses are periodically arrayed, and are arrayed along the vertical and horizontal directions of the illumination apparatus (130).
