  • Light source device
    Patent number: 10845010
    Abstract: The light source device of the present invention has a light source unit having a plurality of LED elements; a first optical system that collimates each of light emitted from the light source unit; and a second optical system that collects a plurality of light emitted from the first optical system. At least one of the light source unit and the first optical system is provided with an adjustment mechanism for adjusting a positional relationship between the light source unit and the first optical system relative to each other.
    Type: Grant
    Filed: January 17, 2017
    Date of Patent: November 24, 2020
    Assignee: USHIO DENKI KABUSHIKI KAISHA

  • Linear light source apparatus
    Patent number: 8905591
    Abstract: A linear light source includes an LED, an LED drive circuit substrate disposed on a frame, a flexible substrate on which an electric supply pattern is formed and to which the LED is attached at one end and the LED drive circuit is attached at the other end, a linear light guide and a heat sink. The one end of the flexible substrate is attached to the heat sink. A face of the heat sink covered by the LED and a face of the one end of the flexible substrate are perpendicular to the light guide and to a substrate face of the LED drive circuit substrate, while a face of the other end of the flexible substrate is parallel to the light guide and a substrate face of the LED drive circuit substrate. A bent portion is formed between the two ends of the flexible substrate.
