A lens includes an incident surface through which outgoing light enters the lens, the incident surface being formed at a portion opposed to a light source, and an emission surface through which incident light incident on the incident surface exits from the lens. The incident surface refracts outgoing light in a direction away from an optical axis of outgoing light, along a direction orthogonal to the optical axis. The emission surface refracts incident light in a direction away from a centerline of incident light, along a direction orthogonal to the centerline.

An LED lighting device includes a transparent cover member arranged at an exterior member or an interior member and covering an LED element and a light emitting surface of the LED element mounted on a substrate, and a light transmission member receiving emission light from the light emitting surface of the LED element at a light inlet end and operating as a light transmission path. The light transmission member is integrated with the LED element mounted on the substrate together with the cover member using a transparent resin by insertion molding.

A replacement lighting apparatus for automobiles is slim and includes an industry-leading footprint to fit into modern headlamps' minimal housing space. The lighting apparatus employs chip scale package light emitting diodes (CSP LEDs), flexible metal heat sinks, an improved collar having a watertight seal formed with an elastomeric gasket and the use of at least one, if not multiple, set screws, a wire harness with a nylon braided sleeve, and a solid-state design for maximum performance, long life, and superior scientifically proven heat mitigation.

A lighting element includes a circuit board defining a longitudinal axis and including at least one illuminator thereon, a housing having at least one flexible element in the optical pathway of the at least one illuminator and in register with the at least one illuminator on the circuit board, and with opposing axial ends.

Provided is an internal pressure adjustment member to be attached to an outer surface of a housing, the member having high air permeability even when a differential pressure that can be generated between the inside and the outside of a housing to which the internal pressure adjustment member is attached is small, and inhibiting damage to the member and a reduction in the air permeability of the member due to coming soil and mud. The internal pressure adjustment member includes: a filter portion including a net-like or mesh-like support layer and first and second porous polytetrafluoroethylene (PTFE) membranes laminated on the support layer such that the support layer is interposed therebetween, the first porous PTFE membrane being exposed on one surface of the filter portion, the second porous PTFE membrane being exposed on another surface of the filter portion; and an adhesive portion, formed on the one surface of the filter portion, for attaching the filter portion to the outer surface of the housing. The first porous PTFE membrane and the second porous PTFE membrane each have an average pore diameter of 2.0 μm or more, the filter portion has a thickness of 140 μm or less, and the filter portion has a density of 0.60 g/cm.sup.3 or less.

The present disclosure discloses an automotive LED headlight and manufacturing process. The automotive LED headlight includes a radiator integrally formed and a PCBA board, wherein a hole is arranged in the center of the radiator and used for accommodating an end portion of the PCBA board, and the end portion of the PCBA board is tightly connected with the radiator. The present disclosure has the advantages of good heat dissipation effect, simple processing technology, and low material and manufacturing costs.

A ventilation member is attached to a through hole of a housing. The ventilation member includes: a support body in which a ventilation path that forms a flow path for gas between the interior and the exterior of the housing; a sealing member that seals between the support body and the housing; a ventilation membrane that is provided on the ventilation path to prevent a liquid and a solid from passing through and to allow gas to pass through; and a surrounding portion that is provided to the support body and is formed with a uniform height to surround an end portion opening of the ventilation path.

A vehicle luminaire according to an embodiment includes: a socket including a mounting portion and a plurality of bayonets provided on an outer surface of the mounting portion; and a light-emitting module provided inside a first recess of the mounting portion which opens on one end of the mounting portion. The light-emitting module includes a board, a wiring pattern provided on a surface of the board, and a light-emitting element electrically connected to the wiring pattern. The mounting portion includes at least one second recess that opens on a bottom surface of the first recess. When viewed from a direction along a central axis of the vehicle luminaire, the second recess is provided between a side of the board and an inner wall of the first recess that faces the side.

A lighting system is disclosed that may be used for marine applications. The lighting system comprises a light strip support structure, a first light strip comprising a first plurality of lighting elements, including light elements of different colors, a second light strip comprising a second plurality of lighting elements, the second light strip positioned above the first light strip and configured to emit only white light, a light element controller electrically connected to the first light strip, wherein the light element controller is configured to control the illumination of the first plurality of lighting elements and not the second plurality of lighting elements and a connector configured to mate with a watercraft stern connector.
