An illuminating device comprises a base, a light source and at least one first layer, wherein said light source is assembled on said base to emit a first color temperature light, while first layer is located on the base along the first light irradiation path. The first light is passed through the first layer to react with said first layer to form a second color temperature light for emission, wherein said first color temperature is ranged from 2800K to 20000K, while excitation wavelength range of said first layer is mainly beyond the wavelength of ultraviolet lights for further adjusting the second color temperature range.

An illuminator for a high energy remote lighting system includes a light source for generating light energy and a selectively positionable light output modifying apparatus having a plurality of light output modifying elements, each element corresponding to a predetermined position of at least a portion of the apparatus. At least some of the light output modifying elements of the apparatus are configured to filter light energy to provide either dimmed or colored light. The illuminator can be implemented in a system having a plurality of area control panels, each control panel generating a control signal indicative of a corresponding light characteristic, the illuminators each being coupled to a corresponding one of the area control panels to receive the control signal and to output a particular type of light in response thereto.

A white light emitting luminaire includes a plurality of LEDs in each of the colors red, green, and blue with a separate power supply for each color and a photodiode arranged to measure the light output of all the LEDs. The light output of each color is measured by an electronic control circuit which turns off the LEDs for the colors not being measured in a sequence of time pulses. The measured light output for each color is compared to a desired output, which may be determined by user inputs, and corrections to the current for each color are made accordingly.

A color light emitting device comprises a casing, six tubular light sources within the casing, and a reflecting surface. The casing has a bottom surface portion and a side surface portion extending from a peripheral edge of the bottom surface portion. The reflecting surface is provided on each of the bottom surface portion and the side surface portion. The six light sources are arrayed substantially in parallel with the bottom surface in the order of red, green, blue, red, green and blue. The outer-peripheral surface of the red color light source at one end faces the side surface portion. The reflecting surface has a colored portion that is in the proximity of the red color light source at one end. The colored portion is colored to have a blue color which is not a green color disposed near the red color light source at one end, of the green color and blue color. As a result, in the proximity of the red color light source at one end, the amount of red color light decreases and the amount of blue color light increases. For this reason, the luminance balance in the proximity of the side surface portion at one end becomes uniform as at the central part, whereby color unevenness is suppressed.

A color adjustable light conducting apparatus is disclosed for use in combination with a standard fiberoptic illuminator having a light output port. The apparatus includes an elongate, light transmitting fiberoptic cable or other type of conductor. A fitting and a color adjuster is carried by a distal end of the cable. The color adjuster may include a filter wheel that is rotated to position a selected color filter in the cable. A fitting and a second color adjuster may be attached to a first end of the cable for interengaging the fiberoptic illuminator.

A lighting device includes a thin transparent plate in which a plurality of micro-lenses arranged in a matrix are integrated. A second thin transparent plate is supported so as to be movable relative to the first plate by means of at least one pair of flexures. A plurality of micro-lenses arranged in a matrix are also integrated in the second plate.

A method for producing a luminous beam uses a chromatic element which can be shifted with respect to the beam axis. The chromatic element is arranged in a precise point inside the optical equipment for which the element is designed. The chromatic element or filter is arranged in an optical zone called the "pupil" and consists of plurality of circular sectors which are equal to each other, for instance each sector may occupy 120 degrees. The sectors each have different colors. The so-obtained filter is thus positioned in the pupil zone in such a way that the filter may be shifted orthogonally to the optical axis in order to choose and/or use or select an infinite range of colors or chromatic or luminous intensities.

A compact and efficient theatrical light that includes four mirrors, a gobo apparatus a colorchanger/dowser/diffusion system, and a lens system. The light beam is reflected four times, each time by 90 degrees. The second reflection is perpendicular to the plane formed by the initial path of the beam and the path after the first reflection. The gobo, the lens system and the colorchanger/dowser/diffusion system are located between the second and the third mirrors. This achieves a very compact, but fully capable light which may be attached to and protected by a truss system when in use and when in transport. Also discussed is a simple color changer/dowser/diffusion system with color glass panels mounted to tracks and moveable into and out of the optical path by cables connected to each panel.

A transparency intended for use in a high intensity light beam projector for stage lighting purposes, comprises a glass substrate (10) having selected areas (11) thereof coated with a multi-layer dielectric coating forming a dichroic color filter. Selective coating is effected either by removing parts of an overall multi-layer coating through a mask, or by applying the multi-layer coating selectively through a mask.
