A light source unit includes a substrate and a light source. The light source is mounted on the substrate. At least one sensor is configured to detect the infrared light. The at least one sensor detects a wavelength component of the infrared light in a range of wavelengths from 920 nm to 960 nm better than a wavelength component of the infrared light out of the range. The light source device emits the infrared light having a peak wavelength smaller than 920 nm when the light source has a temperature of 25&#xb0; C. or lower. The peak wavelength of the infrared light emitted from the light source device increases as the temperature of the light source increases from the temperature of 25&#xb0; C.

Light source unit and movable body

A moving-body light-emitting device for a vehicle includes: a light source including a light-emitting element; a substrate on which the light source is provided; a first lens that covers the light-emitting element and includes a curved surface that transmits light emitted from the light-emitting element, the curved surface including a first curved surface and a second curved surface; and a reflective surface that covers the first curved surface of the first lens and reflects the light transmitted through the first lens. The second curved surface of the first lens is not covered with the reflective surface, and transmits the light reflected by the reflective surface.

Light-emitting device, illumination apparatus, and moving body

A lighting apparatus for vehicle use that projects light forward includes a base, a low beam lamp including a low beam light emitter disposed on the base, a first light emitter disposed on the base and a second light emitter. A lighting controller turns on the low beam light emitter, the first light emitter, and the second light emitter, and an optical system reflects light from the first and second light emitters at least above and below the first and second light emitters, to produce a light distribution pattern. Centers of areas illuminated by the light from the first and second light emitters are horizontally spaced from each other.

Lighting apparatus and automobile including the same

A lighting device for use with a mobile object includes a lamp having a through-hole, a lamp mount for fixing a lamp to a vehicle body, and a support that is shaft shaped and supports the lamp in a predetermined attitude relative to the lamp mount. The lamp mount has an insertion hole through which the support is to be inserted. The support includes, at the leading end side in the axial direction, a male threaded section to be inserted in the through-hole and, at the trailing end side in the axial direction, a trunk section having approximately the same diameter as the diameter of the insertion hole. The trunk section includes a communication portion that communicatively connects the leading end side and the trailing end side of the trunk section.

Lighting device, mobile object, and support

A lighting apparatus to be installed on a mobile object includes: a heat dissipator having a first outer surface and a second outer surface different from the first outer surface; a first light-emitting device thermally coupled to the first outer surface of the heat dissipator; a second light-emitting device thermally coupled to the second outer surface of the heat dissipator; a reflector that reflects light emitted from the first light-emitting device; a first lens that is disposed in a path of light reflected by the reflector and that transmits the light from the reflector along a predetermined lighting direction; and a second lens disposed in a path of light from the second light-emitting device.

Lighting apparatus and mobile object including the same

Lighting apparatus for a vehicle includes: night-time low beam light source which mainly illuminates a lower front region in front of the vehicle; and daytime light source which mainly illuminates an overhead region above the lower front region.

A lighting apparatus for vehicle use that projects light forward includes: a base; a first light emitting device disposed on the base; a second light emitting device disposed on the base; a first lens body disposed in front of the first light emitting device; a second lens body disposed in front of the second light emitting device; and a light restrictor adjacent to the first lens body, the light restrictor restricting light emitted by the second light emitting device from entering the first lens body.

A lighting apparatus for vehicle use that projects light forward includes: a base, a low beam lamp including a low beam light emitting device disposed on the base; a first high beam lamp including a first high beam light emitting device disposed on the base; a second high beam lamp including a second high beam light emitting device disposed on the base; and a lighting controller configured to turn on the low beam light emitting device, the first high beam light emitting device, and the second high beam light emitting device when high beams are turned on. A center of an area illuminated by the first high beam lamp and a center of an area illuminated by the second high beam lamp are horizontally spaced apart from each other.

A lighting apparatus for vehicle use that projects light forward includes: a base; a low beam light emitting device disposed on the base; a high beam light emitting device disposed on the base; a lens body disposed in front of the low beam light emitting device and the high beam light emitting device; and a first light restrictor disposed in front of the high beam light emitting device, the first light restrictor restricting light emitted by the high beam light emitting device from traveling downward.

A lighting apparatus includes: a base that is open toward a front and includes a low beam light-distribution pattern forming component; a lens body disposed forward of the base; a first light-emitting device; and a second light-emitting device. Incident light is refracted in a lower portion of the lens body, and the incident light and exiting light travel in substantially same direction in an upper portion of the lens body. The first light-emitting device is disposed behind the lower portion of the lens body, the second light-emitting device is disposed further forward than the first light-emitting device and behind the upper portion of the lens body, and the low beam light-distribution pattern forming component is disposed in front of the first light-emitting device.

A lighting apparatus includes a ring-shaped light guide including ring-shaped light entry and light exit faces; and light-emitting devices arranged in a ring at predetermined intervals, at positions opposite the light entry face. The light guide includes collimating portions that collimate light emitted from the light-emitting devices.

[Problem] To provide a composite film having light-curing property and weather resistance. [Means for solving] A composite film is one that comprises at least a urethane polymer, wherein both an initial b* value of the composite film measured by a spectrocolorimeter (value at an angle of 15 degrees) and a b* value after performing an accelerated weathering test for 120 hours (value at an angle of 15 degrees) are 4.0 or less, and a non-volatile component after heating the composite film at 130&#xb0; C. for two hours is 96% or more.
