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. Fondasi material: performa yang sangat baik dari bahan transparan kelas optik Pelat pemandu cahaya sama sekali bukan bodi transparan biasa. Ini memerlukan material yang memiliki transmisi cahaya yang sangat tinggi (biasanya> 92%), tingkat hamburan yang rendah dan stabilitas mekanis yang sangat baik. Polimetil metakrilat (PMMA) dan polikarbonat (PC) telah menjadi arus utama. PMMA memiliki transmisi cahaya hingga [...]
1. Revolusi sumber cahaya: Transisi hijau dari CCFL ke LED Sumber daya inti sistem lampu latar telah mengalami perubahan mendasar. Meskipun lampu fluoresen katoda dingin (CCFL) awal memiliki kecerahan yang istimewa, namun konsumsi energinya yang tinggi dan ukurannya yang besar, telah menjadi belenggu teknis. LED cahaya putih telah sepenuhnya membentuk kembali standar industri dengan [...]
1. Munculnya teknologi interaksi multimodal: peningkatan komprehensif dari sentuhan ke antarmuka otak-komputer Teknologi sentuh tradisional masih menjadi arus utama HMI (menyumbang lebih dari 60% dari pasar global), tetapi tingkat penetrasi suara, gerakan, dan antarmuka otak-komputer telah meningkat secara signifikan. Pada tahun 2025, ketiganya bersama-sama menyumbang 25% dari [...]
Abstrak Sebagai komponen inti dari teknologi tampilan modern, pelat pemandu cahaya (LGP) mengubah sumber cahaya garis menjadi sumber cahaya permukaan yang seragam melalui desain optik yang presisi, dan banyak digunakan dalam layar LCD, kotak lampu iklan, peralatan medis, dan pencahayaan cerdas. Prinsip intinya didasarkan pada pembiasan, refleksi, dan difusi cahaya, dikombinasikan [...]
