摘要： A luminaire includes a lamp barrel having a light source detachably connected with a lens assembly. The lens assembly includes a lens barrel detachably connected with the lamp barrel and a focusing member on the lens barrel. An adjusting assembly includes a rotatable focusing ring, a lens fixing ring and a lens. The focusing ring includes a spiral groove on an inner surface. The lens fixing ring includes a projected rail on an outer surface. The lens barrel includes a bar shaped through hole extending along an axial direction. The projected rail passes through the bar shaped through hole and is mated with the spiral groove by clearance fit. Rotation of the focusing ring acts on the projected rail through the spiral groove and drives the lens fixing ring and the lens forward and backward in the lens barrel to adjust a distance between the lens and the light source.

摘要： A light irradiation device includes a light source, an optical member and a sensor. The light source emits light. The optical member is supported so as to rotate around a rotation axis and includes a prism part that emits detection light based on the light. The sensor receives the detection light and detects a light amount of the detection light. The light amount of the detection light received by the sensor changes depending on a position of the optical member in a rotation direction when the optical member rotates.

摘要： A recessed lighting fixture comprises a generally annular body having a central cavity in the form of a partially spherical socket. There is a lighting support member having a partially spherical exterior portion which is closely fitted within the partially spherical socket of the annular body. The lighting support member is pivotable relative to the annular body, but air flow between the partially spherical socket of the annular body and the partially spherical exterior portion of the lighting support member is substantially restricted. There may be a light source mounted to the lighting support member adjacent a bottom thereof. The light source may be a light-emitting diode.

摘要： LED related lighting methods and apparatus are described. Various features relate to water tight light fixtures. Some of the fixtures are spotlights while other fixture are intended for in ground use. The light fixtures in at least some embodiments include power control features. In spotlight embodiments beam angle and power or light output can be controlled without opening the light assembly or compromising the water tight seals which also protect against dirt. In ground embodiments support tilt angle setting which allow a user to set the light fixture to one or more tilt angles. Beam angle can also be changed in some embodiments as well as power control. Beam angle, power control and tilt angle adjustments are supported in some embodiments but need not be supported in all embodiments with some embodiments using one or more of the described features but not all features.

摘要： A light fixture for waveguided ambient light is described herein. In one embodiment, the light fixture includes an LED light source for emitting light rays, a waveguide optically coupled to the LED light source to receive and guide the emitted light rays from a proximal end of the waveguide to a distal end of the waveguide, a first indirect lighting surface configured to receive a first portion of the emitted light rays and reflect the first portion at a first distribution to produce a first ambient light source, and a second indirect lighting surface configured to receive a second portion of the emitted light rays and reflect the second portion at a second distribution to produce a second ambient light source.

摘要： The invention provides a portable lighting device with an elongated main body that includes a housing with receiver, and a power source positioned within the receiver. An operational mode selector assembly with a switch assembly that is actuated by a user is operatively coupled to the power source. An illumination assembly is electrically coupled to both the operational mode selector and the power source. The illumination assembly has a primary light source with a light emitter that emits light axially along a longitudinal axis of the main body or housing through a lens. A secondary light source with a light emitter emits light substantially perpendicular to the axis to illuminate an indicia located in a side region of the illumination assembly. During operation of the portable lighting device, the components of the illumination assembly are arranged such that: (i) the primary light source does not illuminate the indicia, (ii) the secondary light source does not emit light through the lens, (iii) an appreciable amount of light emitted from the primary light source does not mix with light that is emitted from the secondary light source within the portable lighting device, and (iv) an appreciable amount of light emitted from the secondary light source does not mix with light that is emitted from the primary light source within the portable lighting device.

摘要： A light fixture includes a housing, a light source, and a zoom mechanism. The light source is supported within the housing and emits light. The zoom mechanism selectively varies a beam angle of the light emitted from the light fixture and includes a lens and a movable element. The lens is fixed relative to the light source. The movable element is movable relative to the lens between a first position and a second position. The lens reflects a portion of the light emitted by the light source via internal reflection when the movable element is in the first position. The movable element is closer to at least a portion of the lens when the movable element is in the second position to at least partially frustrate the internal reflection.
