Abstract:
An indicator light is disclosed herein. The indicator light can include a housing having at least one wall, where the at least one wall forms a cavity, and where the housing has a first length. The indicator light can also include a light guide disposed within the housing at a distal end of the housing, where the light guide has a second length that is less than the first length. The indicator light can further include a light source disposed adjacent to the light guide. The housing and the light guide can form a flame path therebetween.
Abstract:
A light fixture includes a housing defining a recessed cavity. The housing has a top, a first side, and a second side each extending at an angle from a first end of the housing to a second end of the housing, the first end being substantially orthogonal relative to a first plane. One or more lamp units are positioned in the housing to emit light therefrom, wherein the emitted light is prevented from leaving the housing in a direction parallel to the first plane.
Abstract:
A system for growing a plant includes an inwardly reflective enclosure and preferably a top. A plurality of LEDs, preferably controlled by a control unit, selectively emit light onto predetermined portions of the plant. The control unit controls the growing conditions inside the enclosure with the use of air vents and air flow, an optional heater, and feedback from light intensity and color sensors. The inwardly reflective enclosure can be formed of inner and outer walls with a reflective film sandwiched in between. If desired, a recycling collar can be used with any of the LEDs to increase the intensity of the light ray. The top cover can be formed of a plurality of panels rotatable about their longitudinal axis between a closed position and open position. In another embodiment, pair of inwardly reflective enclosures share a common, reflective wall with holes. The two enclosures are operated tlirough light and dark cycles so as to exchange oxygen and carbon dioxide alternately with one another
Abstract:
An optical system comprising a non-specular ceramic reflector surrounding one or more electrode-less bulbs containing a fill that forms a light-emitting plasma when excited, to be used in a fixture for illuminating subjects, for the purpose of high output lighting. This ceramic reflector generates a uniform lambertian reflection specifically evening out the light emission from the electrode-less bulb producing a uniform beam of light with a spread between about 1 to about 300 degrees; the ceramic reflector greatly increases the amount of light falling on a given subject. The beam of light created by this optical system may then be altered by the fixture by using a combination of further- optical elements including but not limited to one or more lenses, reflectors, mirrors and filter materials, which may be mounted inside or outside of the light fixture. The lenses and/or filters can be adjusted in distance from the light elements.
Abstract:
A light modifier for an LED producing light about a central axis is provided. The light modifier includes a lens defining an indentation. The indentation is angled relative to the central axis by an amount less than a complementary angle of a critical angle of the lens along the indentation. The lens can reduce the appearance of a bright spot created by the LED.
