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.

The present invention relates to a dummy element, in particular a dummy vehicle, comprising a dummy body having an illumination area which simulates an illumination device to be simulated of an element to be simulated, in particular a vehicle, the illumination area having on its surface graphic contours which reproduce a frame of the illumination device to be simulated, and an illuminant, wherein the dummy body comprises, in the illumination area, an opening in which the illuminant is arranged.

Provided is a refrigerator and control method for refrigerator and method for opening a refrigerator door. While a user is holding an object in both hands, a door may be automatically and additionally opened using another part of a body other than hands.

An oven having an illumination device for illuminating an oven cavity, the illumination device may include a light source having a printed circuit board (PCB) arranged exterior to the oven cavity, a light guide extending from the PCB to direct light into the oven cavity via an inlet defined in the frame, and a metal cylinder surrounding the light guide at the inlet to protect the module against microwave leakage.

A lighting device disclosed in an embodiment of the invention includes a substrate; a plurality of light emitting devices on the substrate; a first reflective layer on the substrate; a resin layer on the first reflective layer and including a first surface from which light emitted from the light emitting device is extracted; a second reflective layer on the resin layer; and a light extraction layer on the first surface of the resin layer, wherein the first surface of the resin layer has a convex portion having a convex exit surface facing to each of the light emitting devices, and concave portions between the convex portions, and the light extraction layer may include a first extraction portion having protrusions on each exit surface, and second extraction portions concave between the plurality of protrusions.

The invention discloses an illuminant flowerpot. The illuminant flowerpot comprises a first barrel, a second barrel and a light source. The first barrel is provided with a first bottom plate and a first circumferential side plate, and the first bottom plate and the first circumferential side plate enclose a first accommodation cavity opened upwards. The second barrel is provided with a second bottom plate and a second circumferential side plate, and the second bottom plate and the second circumferential side plate enclose a second accommodation cavity opened upwards. The second barrel is accommodated in the first accommodation cavity, a mounting gap is kept between the second bottom plate and the first bottom plate, and a light guide gap is kept between the second circumferential side plate and the first circumferential side plate.

The present disclosure provides a flexible LED light-emitting lamp strip including a long strip-shaped flexible circuit substrate as well as a plurality of light-emitting units arranged in a length direction of the circuit substrate and welded to the circuit substrate. The plurality of light-emitting units are connected in parallel with one another, and each of the plurality of light-emitting units includes a front light-emitting LED lamp bead, a first side light-emitting LED lamp bead and a second side light-emitting LED lamp bead. A light-emitting direction of the front light-emitting LED lamp bead is perpendicular to the length direction of the circuit substrate, and a light-emitting direction of the first side light-emitting LED lamp bead and a light-emitting direction of the second side light-emitting LED lamp bead are parallel to a width direction of the circuit substrate and are opposite to each other, wherein the front light-emitting LED lamp bead, the first side light-emitting LED lamp bead and the second side light-emitting LED lamp bead are connected in series with one another.

A light fixture includes a housing configured to be secured to a support surface. The housing includes a first end, a second end, and a first and a second side extending between the first end and the second end. A control component is positioned in the housing. A reflector assembly is positioned in the housing. A light emitter is connected to the reflector assembly. A door assembly is releasably connected to the housing. The door assembly has a frame bordering a central opening, a lens, positioned over the central opening, and a gasket positioned between the lens and the frame.

A cordless, battery powered lighting device is disclosed which is configured to be removably installed on a distal end portion of a handheld electrosurgical instrument, and once the lighting device is installed on the distal end portion of the instrument, light automatically projects from the lighting device along the longitudinal axis of the surgical instrument.
