4results about How to "Improve visual comfort" patented technology

This invention relates to the field of intelligent control technology and discloses a method and system for adaptive brightness adjustment of a display screen. The method includes: acquiring ambient light intensity data and analyzing its changing trends to determine the directional characteristics of light intensity as the basis for adaptive speed adjustment; inputting the adaptive speed adjustment basis into a visual adaptation model to generate smooth curve parameters adapted to human eye characteristics, generating a brightness transition sequence through discretization sampling, and converting the brightness transition sequence into an adjustment instruction set; obtaining a target reference value from the adjustment instruction set, calculating the deviation between the actual brightness and the target reference value through a feedback mechanism to obtain a corrected brightness value; fusing real-time light intensity and historical data to construct a time series set and predicting the expected light sequence to generate a primary and backup adjustment path, adaptively switching based on the light intensity deviation; extracting the current adjustment instruction and transmitting it to the display driver module to achieve gradual brightness adjustment and a visually comfortable state. This method can achieve precise adaptation between human eye characteristics and display device hardware.

The utility model discloses an assembly lamp, including lamp holder and lamp body, the lamp holder includes at least two splice piece and at least one assembly connecting piece, the adjacent splice piece through the assembly connecting piece mutually detachable connection, the assembly connecting piece includes body and external part, the body and the external part are mutually detachably connected, and the body and the external part are mutually detachably connected through the assembly connecting piece. The external component is arranged on the surface of the body and used for increasing the friction force between the splicing connecting piece and the splicing piece, and the lamp body is arranged on the splicing piece and / or the splicing connecting piece. The branch-shaped assembled decorative lighting can be freely assembled or disassembled according to individual requirements, and is flexible and changeable in style.

The utility model discloses a kind of curtain wall decorative lamps, including lamp shell, light source board, lampshade and adjusting mounting seat, light source cavity inside lamp shell is equipped with asymmetric light-reflecting inclined plane A and light-reflecting inclined plane B, cooperate with the light mixing inclined plane in lampshade, light efficient mixing and uniform light emission are realized jointly, effectively eliminate glare and mottle, light source board adopts double-row lamp pearl of staggered arrangement, each lamp pearl is equipped with flexible convex cover, further eliminate stray light, lamp body bottom connects multiple groups of anti-falling rope, guarantee high-altitude safety, its core is adjusting mounting seat adopts worm gear drive mechanism, by rotating knob, stepless fine adjustment of the pitch angle of lamp body can be realized, and using its inherent self-locking characteristic, ensure that angle adjustment is long-term stable after, windproof and anti-vibration, solve the difficult problem that traditional curtain wall lamp adjustment is complicated, easy to deviate.
