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.

An electronic device including elements arranged on a substrate, each of the elements including an insulating layer, a first electrode, a functional layer, and a second electrode in mentioned order starting from a side closer to the substrate. The insulating layer has an inclined portion that is inclined relative to the substrate. The first electrode has a first portion positioned on the inclined portion and a second portion in contact with the functional layer. The second portion has a smaller inclination angle relative to the substrate than the first portion. A thickness of the functional layer positioned on the first portion in a direction normal to a functional layer surface in contact with the first portion is smaller than a thickness of the functional layer positioned on the second portion in a direction normal to a functional layer surface in contact with the second portion.

The present invention provides a lamp comprising: an LED light source; a lens comprising an incident surface and an emergent surface, the incident surface defining a first cavity, and the emergent surface comprising an annular protuberance thereon; and a light filter device accommodated within a space defined by the annular protuberance of the lens, wherein, the LED light source is situated within or proximate to the first cavity, to enable light emitted from the LED light source entering the lens from the incident surface and exiting the lens from the emergent surface to be at least partially transmitted through the light filter device.

Various embodiments herein relate to electrochromic devices and electrochromic device precursors, as well as methods and apparatus for fabricating such electrochromic devices and electrochromic device precursors. In certain embodiments, the electrochromic device or precursor may include one or more particular materials such as a particular electrochromic material and/or a particular counter electrode material. In various implementations, the electrochromic material includes tungsten titanium molybdenum oxide. In these or other implementation, the counter electrode material may include nickel tungsten oxide, nickel tungsten tantalum oxide, nickel tungsten niobium oxide, nickel tungsten tin oxide, or another material.

A light source device, a projector, and a chromaticity adjustment method, which are resistant to a change in the color of emitted light even if used for a long period of time, includes: an excitation light source that emits excitation light; a phosphor wheel that is irradiated with excitation light to convert a part of excitation light into fluorescent light and that emits mixed color light including the fluorescent light and a remaining part of excitation light; motor that rotates phosphor wheel; and an adjustment unit that adjusts the rotational frequency of motor so that the chromaticity of mixed color light emitted from phosphor wheel becomes a predetermined value.

A baby monitor assembly includes an emitter unit and a receiver unit, wherein the emitter unit includes means for sound detection, such as a microphone, means for communication with the receiver unit, a generally flat housing, having a peripheral slit, and a source of light. The receiver unit includes means for communication with the emitter unit, and signalizing means. The emitter unit is suitable and configured for placing under a crib, and is capable of detecting sounds and sending information to the receiver unit upon detection of predetermined type of noise. The receiver unit is configured for receiving information from the emitter unit and notifying the parent, such as using light, sound or vibration signals. A slit in the housing allows for emitting a light beam selectively essentially parallel to the floor, so that it neither shines directly nor reflects into the eyes of the baby and the user.
