摘要： In one method of and apparatus for varying the luminosity of illumination, each of a plurality of light sources has an on state in which it emits light and an off state in which it does not emit light. Each of the plurality of light sources is switched cyclically between the on state and the off state in a sequence over a cycle period. The switching sequence is selected such that the number of said light sources that are on is uniform over the cycle. The luminosity of the illumination is varied by varying the proportion of each cycle for which each light source is switched on.

摘要： A heat sink for an LED downlight utilizes tilted fins forming helical air passages that can enhance thermal performance by 30% over conventional fins. To overcome the thermal challenge of installation within the stagnant hot air of insulated ceiling cans, a heat sink has an integral electrostatic air pump on its exterior, to move hot air downwards and drain the stagnant air from the can by establishing a chimney-like circulation up through the heat sink and back down around the outside of the heat sink. The air mover can be powered by a compact high-voltage, low-current power supply similar to those of neon signs. An embodiment of the heat sink is also revealed that is suitable for cooling an LED replacement for standard screw-in or equivalent light bulbs. This device can perform well in variety of orientations (horizontal, vertical, etc.) and fixtures.

摘要： A general method is disclosed of designing two-component dichroic short-pass filters operable for incidence angle distributions over the 0-30° range, and specific preferred embodiments are listed. The method is based on computer optimization algorithms for an N-layer design, specifically the N-dimensional conjugate-gradient minimization of a merit function based on difference from a target transmission spectrum, as well as subsequent cycles of needle synthesis for increasing N. A key feature of the method is the initial filter design, upon which the algorithm proceeds to iterate successive design candidates with smaller merit functions. This initial design, with high-index material H and low-index L, is (0.75 H, 0.5 L, 0.75 H)̂m, denoting m (20-30) repetitions of a three-layer motif, giving rise to a filter with N=2m+1.

摘要： In greenhouses and other stuctures an excessive amount of sunlight on a hot day may cause overheating or may cause uneven lighting. A sheet is provided which is normally transparent but which becomes white and light-reflective at a predetermined temperature to help keep the structure cooled or help keep its lighting at a constant level. This color is reversible so that the sheet becomes transparent when the temperature falls. In one embodiment, the sheet consists of a unitary transparent plastic resin structure formed with elongated cells which are filled with a thick and viscous gel containing poly (vinyl methyl ether) or other suitable "cloud point" material. The gel helps prevent loss of water through the cell walls and prevents gaps which may occur from migration over repeated cycles of precipitation of the cloud point material, i.e., it helps keep the mixture homogeneous. In another embodiment the sheet comprises a plastic resin film which is coated with a liquid mixture including bentonite and a water solution of poly (vinyl methyl ether) and the mixture is dried and later re-wetted at the assembly site.

摘要： A passive electro-optical tracker uses a two-band IR intensity ratio to discriminate high-speed projectiles and obtain a speed estimate from their temperature, as well as determining the trajectory back to the source of fire. In an omnidirectional system a hemispheric imager with an MWIR spectrum splitter forms two CCD images of the environment. Three methods are given to determine the azimuth and range of a projectile, one for clear atmospheric conditions and two for nonhomogeneous atmospheric conditions. The first approach uses the relative intensity of the image of the projectile on the pixels of a CCD camera to determine the azimuthal angle of trajectory with respect to the ground, and its range. The second calculates this angle using a different algorithm. The third uses a least squares optimization over multiple frames based on a triangle representation of the smeared image to yield a real-time trajectory estimate.

摘要： A lighting device has a light source, a reflector dish with a central opening facing the light source, and a lens between the light source and the reflector dish. The lens is so arranged that light emitted from the source towards the central opening of the reflector dish is diffracted away from the central opening. The reflector dish is arranged to reflect light received from the source through the lens back past the lens and source.

摘要： An embodiment of a collimating downlight has front-mounted blue LED chips facing upwards, having a heat sink on the back of the LED chips exposed in ambient air. The LED chips are mounted in a collimator that sends their blue light to a remote phosphor situated near the top of the downlight can. Surrounding the remote phosphor is a downward-facing reflector that forms a beam from its stimulated emission and reflected blue light. The phosphor thickness and composition can be adjusted to give a desired color temperature.
