　　2. Core Teaching Advantages: Tailor-Made for Educational Scenarios

　　2.1 Ultra-Low Noise Operation for Undisturbed Teaching & Learning

　　Equipped with an advanced dual-fan cooling system and optimized air duct design, our 350 Projector achieves ultra-low noise performance. In standard mode, the noise is as low as 28dB, and in eco mode, it drops to 22dB—equivalent to the sound of a quiet library. This ensures that teachers' lectures and students' focus are not distracted by fan noise during long teaching sessions. The silent operation is particularly suitable for small classrooms, tutoring rooms, and language labs where a quiet learning environment is essential for knowledge absorption.

　　2.2 Energy-Saving & Durable Design for Long-Term Teaching Use

　　Adopting a high-efficiency LED light source and intelligent power management technology, the projector significantly reduces power consumption, with ≤35W in eco mode—ideal for all-day teaching use and helping schools reduce electricity costs. The LED light source has a service life of up to 30,000 hours, which means it can be used for 8 hours a day for more than 10 years without replacing the light bulb, minimizing maintenance downtime and operational costs for educational institutions. Additionally, it meets Energy Star and CE energy efficiency standards, aligning with green campus construction requirements.

　　2.3 Eye-Protective & Clear Imaging for Student-Friendly Learning

　　With 350 ANSI lumens brightness and a 3000:1 contrast ratio, the projector delivers clear and vivid images even in moderately lit classrooms. The built-in eye-protective mode reduces blue light emission, effectively alleviating eye fatigue for students who need to watch the screen for long periods. The native 720P HD resolution and support for 1080P/4K input ensure sharp details of teaching materials, such as textbooks, charts, and experimental videos. The DLP technology minimizes color distortion, and the keystone correction function allows easy adjustment to a perfect rectangular image, ensuring all students in the classroom have a clear viewing experience.

　　2.4 Teaching-Oriented Connectivity & Interactive Functions

　　The projector is equipped with rich connectivity options, including 2×HDMI ports, USB port, and wireless connections (Wi-Fi 5, Bluetooth 5.0), enabling seamless connection with teachers' laptops, tablets, smartphones, and U disks storing teaching materials. The built-in Android 11.0 OS supports pre-installation of education-specific apps (e.g., interactive quiz tools, online teaching platforms), allowing teachers to create engaging lessons easily. The wireless screen mirroring function (AirPlay/Chromecast) enables real-time sharing of student homework and group discussion results, fostering interactive teaching and active student participation.

　　2.5 Compact & Portable Design for Multi-Classroom Deployment

　　With a compact size of 220×165×75mm and a weight of only 1.2kg, the projector is highly portable for teachers to carry between different classrooms. The ABS flame-retardant plastic case is durable and scratch-resistant, adapting to frequent transportation and daily teaching use. Its flexible projection design (30-150 inches projection size) is suitable for various classroom sizes, from small tutoring rooms to medium-sized lecture halls, meeting diverse teaching space requirements.

　　3. Typical Educational Application Scenarios
