Comparison of Technical Routes
Xenon Lamps: Occupy the high-end medical market relying on high radiant energy and 5800K daylight color temperature. However, they have shortcomings such as short lifespan (only 500 hours), low temperature limit (150°C), and high starting voltage, leading to a continuous decline in penetration rate in small and medium-sized equipment.
LED Light Sources: Four-color/five-color multispectral types have become the mainstream choice in mid-to-low-end medical, industrial, and security fields. Their power consumption is only 1/3 of that of xenon lamps, and they support precise dimming, which can meet the low-light imaging needs of sensors like OV2740.
Market Growth
In 2024, the global fluorescent rigid endoscope market reached a scale of 3.9 billion US dollars with a growth rate of 24.3%, directly driving the explosive demand for fluorescent LED light sources;
Driven by China’s hierarchical medical system policy, the procurement volume of endoscope equipment in primary medical institutions has increased by 15% annually, significantly boosting the sales of LED light sources in the 20-50W power range.
Medical Field
Hyperspectral LEDs: Can capture the spectral characteristics of tissues, reducing the missed diagnosis rate by 60%, and are suitable for scenarios such as Helicobacter pylori detection with gastroscopes and laryngeal tumor screening with laryngoscopes;
Miniaturized Design: Patch-type LEDs with a diameter of <3mm, when combined with the OV2740 sensor, can realize the integrated design of pediatric endoscopes with a size of ≤6mm, solving the contradiction between "small size and high brightness".
Industrial/Security Fields
Industrial LEDs: Equipped with additional high-temperature protective coatings, they can withstand humid environments at 60°C, with a lifespan 3 times longer than that of xenon lamps, suitable for scenarios such as pipeline detection and engine block detection;
Security LEDs: Integrated with intelligent dimming algorithms, they can automatically adjust brightness according to monitoring distance, reducing glare interference by 40%, and are suitable for scenarios such as narrow-gap monitoring and equipment compartment detection.
Medical Field
Core Requirements: Color rendering index Ra≥95, support for precise dimming;
Mainstream Light Sources: Five-color LEDs, 300W xenon lamps;
Adapted Equipment: Electronic gastroscopes, laparoscopes, otoscopes;
Compliance/Performance Thresholds: Must meet the FDA IEC 60601-1 medical standards.
Industrial Field
Core Requirements: Temperature resistance of -20~80°C, lifespan ≥10,000 hours;
Mainstream Light Sources: Industrial-grade monochromatic LEDs;
Adapted Equipment: Pipeline endoscopes, engine detection scopes;
Compliance/Performance Thresholds: Must meet the IP67 waterproof rating and have electromagnetic interference resistance.
Security Field
Core Requirements: Low power consumption, anti-glare;
Mainstream Light Sources: Zoomable LED arrays;
Adapted Equipment: Narrow-gap monitoring endoscopes, equipment compartment detectors;
Compliance/Performance Thresholds: Flicker-free supplementary lighting, compatible with 1080P@60FPS imaging requirements.
Technical Compatibility Issue: There is spectral conflict between light sources and sensors (e.g., OV2740) → Launch an "integrated light source-sensor calibration solution", customize 405nm/635nm dual-band LEDs to match the spectral response curve of CMOS sensors.
Balance Between Cost and Lifespan: Xenon lamps have high unit price (over 2,000 yuan) and short lifespan (500 hours), resulting in high replacement costs for small and medium-sized hospitals → Promote 200W quasi-xenon LEDs in the mid-end market, with color temperature close to 5800K, lifespan up to 20,000 hours, and unit price reduced to less than 800 yuan.
Insufficient Disinfection Resistance: 20% of medical light sources experience lampshade cracking and dimming failure after high-temperature and high-pressure disinfection → Adopt quartz glass lampshades + silicone gaskets, which can withstand 134°C steam disinfection for 50 times without performance degradation.
