Automatic maximum brightness color matching realizing method for color lamp and color modulation method and system

ActiveCN109496035ATake advantage ofColor matching is faster and more accurateElectrical apparatusElectric light circuit arrangementGamutDimmer
The invention relates to the technical field of color lamp illumination, and in particular relates to an automatic maximum brightness color matching realizing method for a color lamp and a color modulation method and system. When the color lamp has three or more than three primary colors, multiple feasible solutions are provided for realizing a certain point in a color gamut space. According to the invention, the maximum brightness color matching algorithm is used to efficiently and accurately calculate the brightness formula of each primary color for the color lamp to realize the coordinate point of a certain color in the color gamut space; the brightness of the color lamp reaches the maximum after color matching; through the maximum brightness color matching algorithm, the brightness formula of a common target color in the color gamut space of the color lamp is calculated; the formulas are stored in a control unit of the lamp; a dimmer can easily call the desired color mixing formulaby adjusting a color matching channel on a console; automatic, fast and precise color mixing is realized with one button; and the maximum brightness is realized after color mixing, so that the brightness resources of the color lamp can be fully utilized.

Vehicle information statistics-based intelligent control method and system for tunnel lighting

The invention discloses a vehicle information statistics-based intelligent control method and system for tunnel lighting. The method comprises the following control steps of counting basic information and traffic flow information of vehicles which pass through a tunnel within representative 12 days in every quarter and determining period partition reference time according to the time spent by the vehicle with the minimum speed for passing in and out of the tunnel; defining a period through a comparison result of a time interval at which the adjacent vehicles enter the tunnel and the period partition reference time; and then making different intelligent control schemes for tunnel lighting during the day and at night separately. A segmentation node of day and night is found out according to the statistical result of the tunnel vehicle information, and different control schemes are adopted for a lighting system in the tunnel in two periods, so that the stability of the lighting system is ensured and the service life of the lighting system of the tunnel is prolonged on the basis of reducing energy consumption.

Economical direct-type backlight assembly

An economical direct-type backlight assembly comprises a back plate, a reflecting plate, a backlight source, and two to four diffusion sheets. The diffusion sheets are formed by diffusion-type diffusion sheets or light-collecting diffusion sheets in a single or mixed assembly mode; the two faces of the diffusion-type diffusion sheets are each of a regular polygonal groove structure and a lenticular bulge correspondingly for diffusing light rays for multiple times, and thus the light brightness and brightness uniformity are improved; the light-collecting diffusion sheets are each of an ABA structure, one of the outer layer faces on the two sides of each light-collecting diffusion sheet is a pattern face and smooth face, and the other outer layer face is a circular-arc-shaped strip bulge ora triangular strip bulge, a middle layer is composed of a transparent matrix and a light diffusion agent, thus the light ray brightness is further increased while light rays are evenly diffused by thelight-collecting diffusion sheets, and the brightness uniformity of the light source is ensured while the production cost of the direct-type backlight assembly is lowered; and by arranging the relative number of the diffusion-type diffusion sheets and the light-collecting diffusion sheets, the using requirements of the backlight assembly for different brightness are met.
