A lamp unit includes: a laser light source having a CAN type package; a pedestal having a back surface in contact with a heat sink and a front surface on which the laser light source is mounted; and a pressing member that abuts onto an abutting portion of the laser light source and presses the laser light source in a direction toward the pedestal. The pressing member and the pedestal are fixed to the heat sink by fastening with a common fixing member.

A sintered compact includes a wavelength conversion region containing a phosphor material that performs wavelength conversion of primary light and emits secondary light, and a holding region provided to be in contact with the wavelength conversion region. The wavelength conversion region and the holding region are integrated.

Sintered compact and light emitting device

A vehicle lamp includes a planar light-emitting structure having a substrate on which an organic EL emission element is provided, a framing member that fixes the planar light-emitting structure inside a vehicle-lamp light cabinet, and an elastic member that is interposed between the planar light-emitting structure and the framing member and that fixes the planar light-emitting structure by its biasing force.

Vehicle lamp

A light source module has a heat radiating member that has heat radiating properties and has a through-hole penetrating therethrough, a heat generating component having a heat generating component main body disposed on a side of a first opening of the through-hole, and a pin terminal connected to the heat generating component main body and inserted through the through-hole, an electrically conductive member disposed on a side of a second opening of the through-hole and connected to the pin terminal protruding from the second opening, and a covering material that covers and fixes at least a portion of the electrically conductive member and the heat radiating member. A connection portion of the electrically conductive member with the pin terminal is not covered by the covering material.

A planar light emitting bodyconfigured to emit a first illumination light, and a semiconductor light emitting elementconfigured to emit light toward the planar light emitting bodyare disposed in a lamp chamberdefined by a lamp housinghaving an opening and a coverthat covers the opening. The planar light emitting bodyincludes a transmitting layer through which light is caused to pass, and a control layer configured to irradiate light as a second illumination light by controlling a travelling direction of the light that is emitted from the semiconductor light emitting elementand passes through the transmitting layer.

A vehicle lamp includes a semiconductor laser element configured to emit laser light;

A vehicular lamp includes a planar light emitting member having an organic EL light emitting portion at part of a substrate, and a reflecting member and a half mirror that are disposed so as to face each other so that light emitted from the organic EL light emitting portion is reflected repeatedly while allowing part of the light to be transmitted to the front.

A lamp unit has an organic EL panel in which an organic EL light emission portion is formed on a substrate, the organic EL panel being flexible, and a frame that fixes the light emission device so as to cover a light emission area of the organic EL, panel. The frame has a window or a transparent portion at least in a part of a portion, overlapping the light emission area, of the frame. The frame is formed with recess portions at both ends thereof to house both end portions of the organic EL panel.

Light emission device and lamp unit

A light emission device includes an organic EL panel and a molding resin. In the organic EL panel, an organic EL light emission portion is formed on a substrate. The organic EL panel is flexible. The molding resin shapes the organic EL panel so that the organic EL panel is in a curved state.

A vehicle lamp includes a lamp housing having an opening and a cover attached to the lamp housing and closing the opening to form a lamp chamber, and a lamp unit disposed in an interior of the lamp chamber and including a light source having a plurality of planar light emitting bodies. An outer peripheral portion of each of the planar light emitting bodies is a non-light emitting region, and a portion inside the non-light emitting region of each of the planar light emitting bodies is a light emitting region. At least a portion of the non-light emitting region is formed to be transparent. The transparent portion of the non-light emitting region of the planar light emitting bodies and an outer end portion of the light emitting region of other planar light emitting bodies are superimposed to each other in a thickness direction of the planar light emitting bodies.
