摘要:
Color-changing apparatus (12), and an associated method, for a lighting assembly. One or more dichroic filters (34) are selectably positioned in the path of a light beam generated by a light source (14). A positioner (46) supportively positions the dichroic filters (34) and effectuates its translation into and out of the path of the light beam. A set of dichroic filters (34), each separately supported by a separate actuating positioner permits a combination of dichroic filters (34) to be combined to cause the light color of the light beam to be of any desired color.

A lighting system suitable for chromatherapy (10) includes a plurality of light fixtures (12) mounted through walls of a tub basin (16) to project different color light into the water in the tub. The light fixtures (12) are operated by a central control unit (22) and each includes a housing having a concave internal surface. An array of light emitting diodes (78) that project different color light is mounted under a cap (48) covering one end of the housing. A lens (30) is threaded onto the opposite end of the housing from within the tub basin (16) to secure the light fixture (12) to the tub. The concave surface has the different color light projected on it, and reflects light out the light fixture (12) in mixed fashion.

A lighting system comprises a plurality of adjacent light sources of different colors. Each light source has a wide angle beam in a first plane and a narrower angled beam in a substantial perpendicular second plane. As a result, efficient mixing of light is achieved in the first plane.
摘要:
Lighting systems comprising a spectrum former upstream from a reflective pixelated spatial light modulator (reflective SLM), the SLM reflecting substantially all of the light in the spectrum into at least two different light paths, that do not reflect back to the light source or the spectrum former. At least one of the light paths acts as a projection light path and transmits desired light out of the lighting system. The lighting systems provide virtually any desired color(s) and intensity(s) of light, and avoid overheating problems by deflecting unwanted light and other electromagnetic radiation out of the system or to a heat management syste. The systems can be part of another system, a luminaire, or any other suitable light source. The systems can provide virtually any desired light, from the light seen at the break of morning to specialized light for treating cancer or psoriasis, and may change color and intensity at speeds that are perceptually instantaneous.
摘要:
A projector particularly for projecting images in variable dimensions and infinite colors, comprising, on a light beam emitted by a light source (2), a color changer (4) which comprises, for each complementary color, two sectors which have portions which are colored in a complementary color and can be inserted, through motor means, in the light beam.
摘要:
A lamp comprises a support (2) bearing a body (3) from which there is an emission of light, said body (3) containing at least a light-emitting diode or led, preferably a microled, which is associated with a light-filtering means suitable to modify at least partially its color, at least a part of said body (3) being light-transparent, so as to allow the multicolor light rays emitted by the led and filtered by the filtering means to come out, this allowing the use of the lamp for lighting and decorating purposes.
摘要:
A light source includes an array of LEDs in each of a plurality colors such as red, green, and blue in the entrance aperture of a tubular reflector which preferably has convex walls facing the optic axis and flares outward toward the exit aperture, and preferably has a polygonal cross section such as a square. Mixing of colors is further promoted by utilizing a large number of small LEDs with the LEDs of each color being centered on the optic axis.
摘要:
The present invention relates to an illumination apparatus of a microwave oven and a control method thereof by which an illustrated color in a cooking chamber (3) can be changed according to advancement of the cooling process so that a user can ascertain visually how the food is being progressed in the chamber (3). The apparatus comprises a plurality (51) of illumination units (51a,51b,51c) for emitting respectively different colors of light (53a,53b,53c) and a driving unit (57) for driving the plurality of illumination units. The method comprises the steps of inputting a predetermined data for cooking; dividing the input data into mutually different plural color portions according to cooking progressive time steps; reducing the divided data gradually according to the time steps; and lighting up a lamp (51a,51b,51c) of corresponding color (53a,53b,53c) according to the respective progressive time steps by comparing a time progressive reference value for each established step with an actually progressed time.
