A set of primary colors is a set of colorants or colored lights that can be combined in varying amounts to produce a gamut of colors. This is the essential method used in applications that are intended to elicit the perception of diverse sets of color, e.g. electronic displays, color printing, and paintings. Perceptions associated with a given combination of primary colors are predicted by applying the appropriate mixing model (additive, subtractive, additive averaging, etc.) that embodies the underlying physics of how light interacts with the media and ultimately the retina.

The invention provides a mixed-light-source liquid-crystal projection light engine system. The portable liquid-crystal projection light engine system is composed of a light source module, a polarized light management module, an image signal module and a projection lens, wherein the light source module consists of a high-brightness laser, an incoherent LED (Light-Emitting Diode) solid light source, a fluorescent device and the like. The output brightness of the projection system is greatly increased, the light source module is safe and environmentally friendly, and projected images have bright color and clear quality. The polarized light management module consists of a color-combining prism, a polarization beam splitter (PBS), a polarization color-combining device and the like, and different polarization states of three-primary-color mixed light are integrated into the same polarized light to be emitted to the image signal module. The image signal module is a monolithic reflection type liquid crystal light modulation device, and image signals are loaded to the three-primary-color polarized light in sequence according to the image signals corresponding to primary colors. The projection lens is used for projecting the light carrying the image signals onto a screen.

System and method for controlling multiple beams illuminating projected images

InactiveUS8636367B1ProjectorsColor television detailsProjection imageDisplay device

The power and response curves of one or more beams or primaries of beams of a laser projection system illuminating an image on a viewing surface are controlled to desired characteristics during exhibition by monitoring the scanning beams in real time by using at least part of the horizontal blanking time during the scanning of a motion or still image to project a test pattern with one or more of the beams onto a sensor or sensors. The system and method permits real-time balancing and maintenance of the response curves and power levels of each of the beams, and of primary beams of combined beams, to desired targets so as to produce a display field without artifacts and at desired brightness on the viewing surface.

Integrated Micro LED chip and manufacturing method thereof

ActiveCN113270440AAchieve integrationDoes not affect electrical propertiesSolid-state devicesSemiconductor devicesEngineeringFull color

The invention discloses an integrated Micro LED chip and a manufacturing method thereof, and the method comprises the steps: growing a first color epitaxial layer on a substrate layer, and preparing a first color light-emitting unit in a preset shape; the patterned shading film is deposited on the face, away from the first color epitaxial layer, of the substrate layer, the patterned shading film is etched, the light color conversion layer positioning holes are formed, and due to the fact that the light emitting units and the positioning holes are generated based on the preset shape, the designed light color units can be separated by combining the light emitting units and the positioning holes; mixed color light is automatically filtered, and light crosstalk is prevented; and the light color conversion fluorescent materials are not sprayed in partial areas of the light color conversion layer positioning holes, the light color conversion fluorescent materials of the other two colors except the first color in the three primary colors are respectively sprayed in other areas, and the blue pixel unit, the red pixel unit and the green pixel unit can be respectively obtained, so that the full color is conveniently realized. And the complexity of the epitaxial structure is reduced, and integration of a large number of pixels can be realized without huge transfer.

The invention provides an LED device and a preparation method thereof. The LED device comprises an LED semiconductor chip and a semi-transparent glass body, wherein the semi-transparent glass body is formed by sintering on a light-exiting surface of the LED semiconductor chip; the semi-transparent glass body is formed by coating the light-exiting surface of the LED semiconductor chip with a suspension liquid prepared by mixing nanoscale glass powder and red-yellow primary color fluorescent powder and then naturally drying and sintering the LED semiconductor chip; and the preparation method of the LED device comprises the following steps: mixing the nanoscale glass powder with the red-yellow primary color fluorescent powder to prepare the suspension liquid; coating the LED semiconductor chip with the suspension liquid; and naturally drying and sintering the LED semiconductor chip until a coating layer becomes the transparent glass body. The nanoscale glass powder is prepared by doping titanium dioxide and iron trioxide into a glass formula material, so that a 'rich blue light' emitted from the formed LED device can be effectively blocked and absorbed; the harm of the 'rich blue light' to human eyes is reduced; and the light transmittance is improved.

LED plant growth insecticidal lamp based on mixed spectrum

ActiveCN106857455ASaving energy measuresHorticulture methodsDot matrixMixed spectrum

The invention discloses an LED mixed spectrum plant growth insecticidal lamp and belongs to the field of plant LED illumination. The lamp comprises an LED lamp dot matrix, a single chip microcomputer control system, a shell and an insecticidal power grid. According to the LED mixed spectrum plant growth insecticidal lamp, power distribution of a power source which specific mosquitoes are fond of is obtained by experiments, through a specific algorithm, proportions in a target light source of three primary colors of red, green and blue can be obtained, the duty ratio of three path PWM waves sent by the single chip microcomputer control system is changed, and therefore electric current driven by LED constant current can be changed, the illumination power of an LED is changed correspondingly, and the target light source can be obtained. The technical problems can be solved that a common plant insecticidal lamp is single in color and does certain harm to both beneficial insects and the human body, and certain guidance for pest killing by plants and optimization is provided.
