1、 Technical hard power: parameter compliance is only the foundation, extreme scenario verification is the key
1. Optoelectronic parameters must cover harsh working conditions
Taking the UV sterilization scenario as an example, the UVC band (255-280nm) needs to reach50-100mW optical powerOnly then can efficient virus inactivation be achieved. The TO-46 model of Tianshi Optoelectronics has a measured optical power of 85mW in the 265nm band (the industry average is only 60mW), and supports forward current up to 100mA, which can meet the continuous operation requirements of medical grade water treatment equipment.
Practical recommendations：
Request suppliers to provideSpectral and Color Separation Detection ReportFocus on wavelength deviation (within ± 2nm is optimal) and optical power attenuation rate (annual attenuation<3%);
Compare the heat dissipation performance of different specifications: for example, TO-39 and TO-46 have thermal resistances as low as 8 ℃/W and 5 ℃/W, respectively, in the 850nm infrared band. The latter is preferred for high-power scenarios.
2. Limit parameters determine product lifespan
A certain automotive electronics manufacturer once caused the failure of car lights at -30 ℃ due to the use of ordinary LEDs, while the TO-56 model of Tianshi Optoelectronics passed the test-55 ℃~125 ℃ wide temperature testIn the extremely cold region of Northeast China, the actual lifespan has exceeded 80000 hours (industry standard of 50000 hours). Its metal base adoptsCopper nickel plating processThe thermal conductivity reaches 200W/m · K, which is three times more efficient than plastic packaging in terms of heat dissipation.
Practical recommendations：
Priority selection throughISO9001 Quality System CertificationThe manufacturer ensures that the entire process from wafer to packaging is controllable;
Request to provideHigh Temperature and High Humidity Test (HAST) ReportVerify moisture resistance performance (standard is 1000 hours without failure).
2、 Service soft power: From supply to after-sales, the response speed of the entire chain determines the value of cooperation
1. Customization ability to distinguish between top and ordinary manufacturers
A medical equipment company needs to develop a product by 2025415nm Blue LEDFor dental curing, Tianshi Optoelectronics completed wavelength tuning and lens design in just 15 days, while a certain international manufacturer had a quotation cycle of up to 45 days. The secret lies inModular R&D platformIt can quickly match customers' special requirements for emission angle (7 ° -80 °) and half wave width (<15nm).
Practical recommendations：
Check if the manufacturer has the capabilityFully automatic color separation systemThis is the foundation for achieving small batch customization;
Request to provideBOM List Traceability ServiceEnsure that the source of key materials (such as gold wire, fluorescent powder) is traceable.
