1. Physical cornerstone: perfect control of total reflection effect The core magic of the light guide plate comes from the total reflection effect of light at the interface of transparent media. When light is emitted from a high refractive index medium (such as PMMA, refractive index ≈1.49) to a low refractive index medium (such as air, refractive […]
It is in this context that the innovative material PV Light Guiding Film has emerged like the light of dawn. It does not directly participate in the photoelectric conversion, but like a shrewd “light guide”, it optimizes the journey of light in the battery through a unique physical structure, thereby doubling the energy capture efficiency. 1. Breaking […]
1 Technological evolution, a leap from halogen to LED Traditional halogen lamps were once regarded as the “gold standard” for surgical lighting, but their limitations are becoming increasingly prominent. Halogen lamps have a lifespan of only 500-1000 hours, and the light source needs to be replaced every 1-2 months. In addition, high heat radiation accelerates the […]
Today, when liquid crystal display (LCD) technology dominates the visual world, it is the hero behind the scenes – the backlight source that gives it a fresh life. When the traditional cold cathode fluorescent lamp (CCFL) gradually becomes history, LED backlight completely reshapes the display rules with its excellent performance. Understanding its precise working principle is the […]
For a long time, the lights in the operating room have been like silent dancers, and their projection direction and brightness determine the clarity of the surgeon’s vision. From flickering candlelight to dazzling halogen lamps, to efficient LEDs, surgical lighting has undergone a long evolution. However, the inherent limitations of overhead light sources – inevitable […]
Human-computer collaboration significantly improves medical efficiency and resource accessibility Telemedicine breaks the geographical cage: Video consultation and remote monitoring technology enable high-quality medical care to transcend mountain barriers. According to the World Health Organization report, telemedicine can increase the coverage of medical services in resource-poor areas by more than 30%, so that remote patients no longer lose […]
1. materialegrundlag: fremragende ydeevne for gennemsigtige materialer af optisk kvalitet Lyslederplade er på ingen måde et almindeligt gennemsigtigt legeme. Det kræver, at materialet har ekstremt høj lystransmission (normalt >92%), lav spredningshastighed og fremragende mekanisk stabilitet. Polymethylmethacrylat (PMMA) og polycarbonat (PC) er blevet mainstream. PMMA har en lystransmission på op til [...].
1. Revolution inden for lyskilder: Grøn overgang fra CCFL til LED Den centrale strømkilde i baggrundsbelysningssystemet har gennemgået en grundlæggende forandring. Selv om de tidlige koldkatode-lysstofrør (CCFL) havde en fremragende lysstyrke, er deres høje energiforbrug og store størrelse blevet en teknisk hæmsko. Lysdioder med hvidt lys har fuldstændig ændret industristandarderne med [...].
1. Stigningen i multimodal interaktionsteknologi: en omfattende opgradering fra touch til hjerne-computer-interface Traditionel touch-teknologi er stadig mainstream for HMI (tegner sig for mere end 60% af det globale marked), men penetrationsgraden for stemme, gestus og hjerne-computer-interface er steget markant. I 2025 tegner disse tre sig tilsammen for 25% af [...]
Abstrakt Som en kernekomponent i moderne skærmteknologi konverterer lysstyringspladen (LGP) linjelyskilde til ensartet overfladelyskilde gennem præcist optisk design og bruges i vid udstrækning i LCD-skærme, reklamelysbokse, medicinsk udstyr og intelligent belysning. Dens kerneprincip er baseret på lysets brydning, refleksion og diffusion, kombineret [...].
